02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library.

Modules * Fixed pixel format for VP8/VP9 streams in `avformat` producer. * Fixed `yuva422p` pixel format in `avformat` producer. * Added `MLT_AVFORMAT_HWACCEL` & `MLT_AVFORMAT_HWACCEL_DEVICE` environment variables to `avformat` producer. * Updated `decklink` module for recent hardware and drivers. * Added `colorspace` and `color_trc` (including HDR) properties to the `decklink` consumer. * Fixed silencing extra audio channel (e.g. 6 => 8) in `decklink` consumer. * Fixed 5.1 C/LFE channels swapped over HDMI in `decklink` consumer. * Fixed text outline had sharp angles in `kdenlivetitle` producer. * Fixed default gamma to be Rec. 709 for 10-bit Y'CbCr from `movit` module. * Added support for HLG gamma to `movit` module (requires ddennedy/movit fork). * Fixed `opencv_tracker` filter should require multiple keyframes to be ready. * Fixed OpenCV crash on `rect` <= 1 pixel in `opencv_tracker` filter. * Fixed aspect ratio in `qtblend` filter and transition. * Fixed `QT_QPA_PLATFORM=offscreen` not working in qt and glaxnimate modules. * Improved preview scaling in `qtblend` filter. * Fixed requesting huge images on multiple `qtblend` filters or transitions. * Fixed `sdl2` consumer on macOS. * Fixed the `strobe` filter not working with `movit`. * Fixed color and gamma using `timeremap` link with `movit`. * Fixed consumer properties (e.g. `channels`) missing on `qglsl` consumer injected by the `xml` producer. Version 7.30.0 Framework * Fixed `Mlt::Producer::set_creation_time()` not exported on i686. * Fixed `Mlt::Properties::set(int64_t)` symbol version. * Fixed `mlt_factory_init()` on Linux/BSD may fail to initialize when compiled with `-DRELOCATABLE`. * Added generic non-drop-frame timecode in `mlt_property.c`. Previously, it was only done for 30000/1001 and 60000/1001 frame rates, but 24000/1001 is especially important as well. * Added support for MLT XML embedded in chains. This, along with `xml-clip` producer handles mismatching frame rate between parent and child producers and facilites time-affecting links on the child. * Added `mlt_image_full_range(const char *color_range)` where any of the following strings return true (1): `full`, `jpeg`, `pc`. Modules * Added `xml-clip` producer. * Fixed link `in` and `out` properties arenot serialized in the `xml` consumer. * Added `hslprimaries` and `hslrange` filters to the `plus` module. * Added a `gradientmap` filter to the `plus` module. * Fixed `avfilter` audio filters with FFmpeg 7. * Fixed incorrect frame rate for AVCHD (and possibly others) in `avformat`. * Fixed `window_id` property in consumer `sdl2` by using `SDL_CreateWindowFrom()`, especially important for embedding in GTK+ or Qt. * Fixed text not rendering in transition `vqm` since Qt 6. * Added `decimals` keyword to `gpstext` filter and move `RAW` keyword check. * Fixed `time_offset` property handling in `gpstext` filter. * Fixed reading and writing SRT files with unicode in the path. * Fixed `subtitle_feed` filter on producers with an in point > 0. * Fixed opaque alpha channels become translucent in `luma` transition. * Fixed a crash in the `mix` transition with `consumer` producer. * Fixed `freeze` filter freezing too much. * Fixed `avfilter.fillborders` with preview scaling. * Fixed non-proportional scaling in `qtblend` transition and filter. * Fixed `avfilter` color distortion with `mlt_image_rgb` and `mlt_image_rgba`. * Extended support for `colorspace=2020` consumer propeerty and the BT.2020 colorspace in the `avformat` producer and consumer. This does not imply HDR, which is signaled through a `color_trc` property. * Added support for `mlt_image_yuv420p10`, `mlt_image_yuv444p10`, and `mlt_image_yuv422p16` in `avfilter`, `swscale`, and `rescale` filters. This facilitates using these pixel formats end-to-end when using only FFmpeg producers, certain avfilters, and `avformat` consumer. This means it is possible to do 10-bit end-to-end on the CPU when being careful to select compatible components and options to avoid conversions. One can pass-through HDR; however, you must set the `color_trc` and `pix_fmt` properties on the `avformat` consumer (see `ffmpeg -h full` for these values). The `avformat` consumer automatically converts MLT `colorspace` (integer value) to FFmpeg's `colorspace` and `color_primaries` (unless explicit) options.

Version 6.2.0 - April 20, 2016 There are no framework changes in this release. The major announcement is the introduction of support for libavfilter! This is still a work-in-progress. It is limited to FFmpeg 2.3 and up, and there are a number of filters that are black-listed because they are known to not integrate with MLT, which is not a full libav* environment or simple wrapper for it. There are likey avfilters that are not yet black-listed but might not work because they have not been completely tested. Also, they do not support MLT's keyframable property animation nor its frame-threaded parallelism due to architectural or integration limitations. However, some avfilters are slice-threaded (internal parallelism), and that works. Finally, libavfilter filtergraph syntax is not supported either. All of the supported libavfilters are exposed as MLT filters beginning with the prefix "avfilter." All of the avfilter parameters are exposed as MLT properties with the "av." prefix to prevent clashes with MLT properties. You can run `melt -query filters` to see the new avfilters, and `melt -query filter=avfilter.rotate`, for example, to view generated documentation for an individual filter.

Melt * Added '-query profile' option. * Added '-query formats', '-query audio_codecs' and '-query video_codecs'. The recommended version of FFmpeg for use with this release is 0.6.1. Version 0.7.0 - March 27, 2011 This is a major new release due to significant additions to API, framework, and build. Build * Added support for Windows via MinGW. * Enabled linsys module by default. * Disabled VDPAU by default and added --avformat-vdpau to enable it. * Added support for swfdec 0.7. Framework: * Added parallelism to mlt_consumer when 'real_time' > 1 or < -1. * Added mlt_deque_insert() and mlt_deque_peek(). * Added mlt_profile parameter to mlt_producer_new(). * Let transitions with no out point run forever. * Added mlt_frame_unique_properties(). * Added mlt_frame_set_image() and mlt_frame_set_alpha(). * Added mlt_image_format_size() and mlt_audio_format_size(). * Added mlt_filter_get_length() and mlt_transition_get_length(). * Added mlt_filter_get_progress(), mlt_transition_get_progress(), and mlt_transition_get_progress_delta(). * Added mlt_filter_get_position() and mlt_transition_get_position(). * Added mlt_properties_lock() and mlt_properties_unlock(). Modules * Added rotoscoping filter. * Improve libavdevice support (V4L2, ALSA, libdc1394). * Added support for new FFmpeg metadata API. * Various fixes, refactoring, and improvements. The recommended version of FFmpeg for use with this release is 0.6.1. Version 0.6.2 - January 23, 2011 This is just a minor release to address a few things prior to introducing major changes from other branches. * Added force_aspect_ratio property to pixbuf and qimage producers. * Added opacity handling in geometry property of the affine filter and transition. * Added use_normalised property to affine filter. * Added always_active property to affine transition. * Fix building on NetBSD. The recommended version of FFmpeg for use with this release is 0.6.1. Version 0.6.0 - January 1, 2011 The recommended version of FFmpeg for use with this release is 0.6.1. There were quite a few enhancements and changes including a minor interface change. Therefore, this release gets a jump in the versioning. Framework * mlt_profile - Added (Y'CbCr) colorspace attribute. - Added mlt_profile_clone(). * Added mlt_consumer_position() and Mlt::Consumer::position(). * Added Mlt::Properties::wait_for(string). * Added a version API: mlt_version_get_int() and others. * Added Mlt::Producer::pause(). * Added mlt_frame_write_ppm() for debugging. Melt * Added automatic detection of profile from first input when profile not specified. * Now exits with error result when consumer fails fatally. Modules * Added swfdec producer for Flash files including variables support. (Does not support audio.) * Added consumer for Blackmagic Design DeckLink SDI and Intensity HDMI. * Added Y'CbCr colorspace conversion and option to use full luma range. * Added (de)serialization of profile to XML. * Added support for #frame# variable to the data_show filter. * Added support for frei0r string parameters. * Make FFmpeg formats and codecs available as properties (not just stderr). * Try to load .xml file as MLT XML. * Added a consumer-sdl-paused event to sdl_preview. * Added a consumer-fatal-error event to avformat. * Change composite transition to default to progressive rendering; field- based rendering available only explicitly. Version 0.5.10 - September 13, 2010 This is a quick followup to the 0.5.8 release to address an issue I want to address immediately. I noticed an extra unconditional colorspace conversion to and from RGB was added for all YCbCr (YUV) video sources. In addition, I have enabled the avcolor_space filter on OS X since it works now. Version 0.5.8 - September 12, 2010 The recommended version of FFmpeg for use with this release is 0.6. This is a maintenance release to address some bugs that appeared thus far in the 0.5.x series. Beyond that is a few enhancements: * Added EXIF-based auto-rotation of images to pixbuf and qimage producers. * Improved quality of libswscale-based image conversion and scaling. * Added channelswap and panner audio filters; panner also does balance. * Improve audio waveform and add audiowave video filter. * Enhanced luma filter to work with animated filters such as affine. * Automatically crop 8 bottom lines of 1088 source in a 16:9 project (common in Canon EOS digital cameras). * Added support for inline images in kdenlivetitler. Version 0.5.6 - June 20, 2010 The recommended version of FFmpeg for use with this release is 0.6. This is a maintenance release to address some bugs that appeared this far in the 0.5.x series. Beyond that it a few enhancements: * Added interpolation to the affine transition and filter. * Added multi-track audio encoding to avformat consumer. * Added interlaced field rendering to kdenlivetitle producer. Version 0.5.4 - April 19, 2010 The recommended version of FFmpeg for use with this release is SVN r21322. This is another maintenance release to address some bugs that appeared this far in the 0.5.x series. Beyond that it adds two things that only very specific users will see: * Added C# (ECMA CLR) binding (not enabled by default). * Linsys SDI consumer now configures itself from MLT profile. Version 0.5.2 - March 10, 2010 The recommended version of FFmpeg for use with this release is SVN r21322. This is a minor maintenance release, but it is interesting because it now enables usage of libswscale as the default choice for image scaling, image format conversion, and color space conversion. That gives better quality and performance. In addition, there are some improvements in the sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other things: * Fixed mlt++/MltFilteredProducer * Fixed playing to the end in Kdenlive (mantis bug 1207) * Fixed crash load uncompressed video * Fixed compiling yadif for non-sse2 builds Version 0.5.0 - February 15, 2010 The recommended version of FFmpeg for use with this release is SVN r21322.

In particular, this adds support for VDPAU, YADIF, and HD-SDI technologies! configure: added --disable-sse2 framework: * mlt_cache: added mlt_cache_set_size() * mlt_filter: added data property "service" - set when attached * mlt_frame: - added Doxygen docs - added "previous frame" and "next frame" data properties - available when its producer has _need_previous_next=1 * mlt_playlist: added support for negative out point same as length-1 * mlt_service: - added mlt_service_cache_purge() - added "_need_previous_next" handling in mlt_service_get_frame() - added firing event "service-changed" in mlt_service_attach() modules: * avformat producer: - added decoding H.264 with NVIDIA VDPAU Requires FFmpeg built with vdpau. This is automatically detected and enabled. You can disable this by setting environment variable MLT_NO_VDPAU=1 or property novdpau=1. - added caching of FFmpeg contexts and decoded images This allows large numbers of clips in a project avoiding limitations with number of threads and file descriptors permitted per process. You can disable image caching with property noimagecache=1. - added variant of producer named avformat-novalidate - restored support for video4linux(2) * avformat consumer: added apre, fpre, and vpre preset properties * crop filter: added center_bias integer property * deinterlace filter: added the excellent YADIF as a method * kdenlivetitle producer: added text outlining * linsys/sdi consumer: - added support for HD-SDI - changed name from "linsys_sdi" to just "sdi" * oldfilm filter: added "uneven development" effect * xml producer: add support for unspecified out points profiles: * added several missing ATSC (HD) profiles * change descriptions from using Hz to fps Version 0.4.10 - December 8, 2009 The recommended version of FFmpeg for use with this release is SVN r19873.

This document provides a quick reference for the minimal configuration, build and installation of MLT. See the `docs/` directory for usage details. See the [website](https://www.mltframework.org/docs/) for development details and a [contributing](https://www.mltframework.org/docs/contributing/) guide. Configuration ------------- Configuration is triggered by running: cmake . More information on usage is found by viewing `CMakeLists.txt` and the [cmake man page](https://cmake.org/cmake/help/latest/manual/cmake.1.html). Compilation ----------- Once configured, it should be sufficient to run: cmake --build . to compile the system. Alternatively, you can run `cmake` with `-G Ninja` and use ninja to compile. Testing ------- To execute the mlt tools without installation, or to test a new version on a system with an already installed mlt version, you should run: . setenv NB: This applies to your current shell only and it assumes a bash or regular bourne shell is in use. Installation ------------ The install is triggered by running: cmake --install .

Also, please create clips clip1.dv, clip2.dv, clip3.dv, clip1.mpeg, clip2.mpeg, clip3.mpeg, and music1.ogg. Please make sure clips are at least 500 frames duration. These notes explain the the concepts presented in each demonstration and what details to look for. First, a note on consumers. When you start the script, the main menu asks you to choose a consumer. A consumer is like a viewer, but it could also write to a stream/file. The "SDL" consumer is the popular Simple DirectMedia Layer audio and video output. The "xml" consumer generates an XML representation of the service network. That can be played directly due to the XML producer plugin. See https://mltframework.org/docs/mltxml/ for more information. These examples assume the numeric locale LC_NUMERIC decimal separator is a period. Therefore, the demo script sets LC_NUMERIC=C for you, but if you are running these manually or learning from them, remember to use the appropriate separator for your locale. And now the demos... All clips Simply builds a playlist containing each video clip, and you can transport between them using j and k keys. Filter in/out A video filter can be applied to a portion of a producer (clip, playlist, or multitrack). This examples shows the greyscale filter. Watermark A graphic can overlay video in realtime with support for alpha channel. This example uses a PNG file with an alpha channel. Distortion is explicitly enabled here so the otherwise circular graphic is scaled to fill the compositing region. By default, compositing honours the aspect ratio of the overlay. My name is... Titles are very easy to overlay in realtime. The titler uses Pango with the FreeType2 rendering backend. This means it supports high quality scalable font rendering with anti-aliasing, unicode (UTF-8), and Pango markup capabilities. The compsiting here respects the aspect ratio of the rendered title in the first two title pieces but distorts the final one. This demo also shows the motion and scaling capabilities of the compositor in conjunction with honouring aspect. The compositor is doing field-based rendering. So, when displayed non-progressively with SDL, you can see motion artifacts during animation. An overlay transition The affine transition also handles video over video as demonstrated in this usage of affine to create a special transition. This demonstration also crossfades the audio during the transition! Progressive rendering is explicitly enabled on the compositor due to the poor results that would otherwise occur due to scaling an interleaved video frame and moving the video in a reverse direction horizontally. Fade in and out A simple series of transitions between 3 clips using dissolves and audio crossfades. This is easy :-). Clock in and out Wipe transitions are very easy and highly extensible as they are generated using a very convenient lookup table based upon the luma of an image. This image can be a 16 bit PGM (grayscale bitmap) or the luma channel of any video producer. A number of high quality wipes can be downloaded from http://mlt.sf.net/. It also performs field rendering. The second wipe demonstrates the ability to control the direction of the wipe as well. Audio Stuff A music bed sound track can be mixed with a video. The sound track of the video clip has a "floating" amplitude normalisation filter applied. Typically, audio normalisation applies a constant gain factor across the entire duration of an audio segment from a single source where the gain factor is automatically determined by anaylsing the maximum "power" or peak levels. However, in news production, a popular requirement is to to dynamically boost the amplitude in soft areas and reduce the amplitude in louder areas. Thus, the gain analysis is performed using a "sliding window" approach. This example also applies a constant gain factor of 0.5 (50%) to the normalised audio of the video clip (to get a nicer mix level). Audio and Video Levels Audio can be normalised by setting a target amplitude level in decibels. A gamma curve can be applied to the luma channel of video. Shadowed Title and Watermark Two instances of the titler are used to create a shadow effect. The aspect ratio of the watermark in this example is not distorted. Since the original image is a circle with square pixels--a computer-generated image--and ITU BT.601 video is not composed of square samples. Therefore, the compositor normalises the pixel aspect ratio of the overlay to the destination image, and the circular image remains circular on the analog video output. Finally, a greyscale filter is applied to the watermark while its opacity is set at 30%. Station Promo into Story? Here is fun demo that might show using a still graphic with some music to introduce a show. A luma wipe with an audio crossfade transitions from the show title or station promotional material. Voiceover 2 clips with title A common news production requirement to have a "voiceover" audio track to a clip or even multiple clips as demonstrated here. Likewise, it is common to place a title caption on the video at the same time! This demo has a little fun with the titler at the sake of practicality :-) The foreground of the title is transparent while the opacity of the background is reduced to blend with the video. Meanwhile, the compositor stretches the image to fill the bottom slice of the video--not suitable for overscan displays ;-) Also, pay close attention to the mixing levels of the audio tracks. The audio of the video fades out as the voiceover track (just music in this demo) fades in. Then, the voiceover remains mixed with the ambient audio at a 60% level. Finally, the voiceover fades out smoothly from the 60% level to nothing. GJ-TTAvantika title This demo requires a special TrueType font called Avantika. If you have the font, register it with fontconfig using the fc-cache utility. This demonstrates i18n capabilities of the titler and the alignment capabilities of both the titler and the compositor. The titler centre aligns the two lines of text, and the compositor centre aligns the title horizontally on the frame. Title over graphic You can superimpose a title over a graphic over video! Also, you can apply a luma wipe to the compositor! Slideshow This demo requires any number of JPEG images with the extension ".jpg" in a subdirectory named "photos." Bouncy, Bouncy The "watermark" filter encapsulates the compositor, and you have full control over the compositor properties. Who says a watermark can not also be a video?! Bouncy, Bouncy Ball A variation on the above Bouncy, Bouncy demo that applies a shape, or alpha producer, to the the compositing region. Breaking News This demonstrates layout capabilities of the compositor. Squeeze Transitions This demonstrates a distorting barndoor-like wipe. J Cut A J cut is an edit where the audio cuts before the video. It gets its name from the way it looks on a NLE timeline user interface. When the audio cuts over, it does an audio crossfade over the duration of one frame. This makes the audio cut slightly less abrupt and avoids any "click" due to mismatched sample levels at the edit point. The video edit is a hard cut. L Cut An L cut is an edit where the video cuts before the audio. It gets its name from the way it looks on a NLE timeline user interface. This demo shows a very quick dissolve over 5 frames for a soft video cut. Like the J Cut demo, an audio crossfade for the duration of one frame makes an audio edit nearly instantaneous while being slightly softened and avoiding aberrations. Fade from/to black/silence Of course, it is possible using MLT to fade from black on video and silence on audio as well fade to black and silence. Push wipe A push wipe is a somewhat fancier transition than most standard wipes because it involves motion. The new video clip "pushes" the old video clip off one edge. If you can preview on an analog monitor you will notice how smooth the motion is due to field-based rendering. Ticker tape A very minimal reverse crawling title neard the bottom of the screen. The goal of the demo is show fluid motion of the field-based rendering of the compositor when viewed on an analog monitor using a DV or BlueFish444 consumer. The demo also shows the potientional for using and extending the existing set of services for a full blown news ticker implementation. Pango Keyframed Markup You can create timed text and subtitles using a .mpl file, which is a properties format file. A properties file contains key=value pairs on separate lines. For .mpl the key is a frame number and the value is Pango Markup Language. A tilde is interpreted as a new line. This example also demonstrates using the watermark and the alignment properties of its encapsulated transition where halign is the horizontal, valign is the vertical, c is for center, and m is for middle. mlt-7.32.0/demo/circle.png000664 000000 000000 00000012167 15006761523 015266 0ustar00rootroot000000 000000 ‰PNG  IHDR,,y}ŽusBIT|d.IDATxśíÝa°\eyŔń˙˝×$0BbĂ$”(HDef ĄĄkÇi;ĄN?8µ˘ťV«ťvô›ŽÎtŞ3Nż´úˇVeTŔ©Ž #&ŕ@'VB 4$&!q’÷Ţ~xö&››Ý˝gwĎ9ď9g˙ż™göĆ{÷śGö=ĎĽď»ďyĎŇéÎÖ‹%­/™őó"ŕ `0ż Ú^ÇŁŔËŔńÖëĚĎÇ€CŔ~ŕĹÖkűĎ€ť­K'ŚĄN@IŚ—«ZŻ«3S%6ËQŕIŕi`wëuđ8đ0ť*1ĄaÁjľĄŔeŔ[Ú^×Rť˘4¨ŁŔvŕQŕ‘¶×R&ĄbY°šgđ.`#p-p~ŇlĘ÷ p/° ř đ\Ňl”+ Vý-6´b#1÷¤“vĹks+öĄMGĂ°`ŐĎbŕN¨µř9f5M #g Ř}Äżj†^}cŔ DqÚ¬#ľÓ𦀭DńÚÜŤůŇ@Ö_ö‘Q|ěmý7_—áó‘FŢJŕSŔc¤żxG=k}+{~bŇ9 ¸ř10Iú Ő85&[źÍ-­ĎJ9ŔőŔ׀äż(Ťlq¸ő™]ßú ĄF»řÎK5!ö¶>Ë‹‘fp;ůš“­ĎÖ‰zŐŢzŕ‡Ä×ç©/,ŁŘj}Öë‘jć:bmOę‹ČH›‰6 UÖp°…ôŚQŤŘB´ h«2&€ŰHŐŚmDń›E%3ř °ô„QŹŘA´™yH%ÚHl$—ú0ę»6$ę<ŕŇ7xŁqѦ¤\Í#î+;BúFn4+ŽmËa˘rq-±‡Rę†m4;¶mMČrŕë¸čÓ(/¦6·)Ł ŕŁŔAŇ7`c4ă Ń]ˇž®"v LÝ` cšh‹W!Í2ř,˙ŚęĹŃ6ť”Wpňˇś†QŐx‚h«a&Č™ş1F–8J´YŤ…Ŕ·Hß cřцGÎ(ŢEľŽřŔW§NDÂ“Ä Ő[S'R¦QűÚôV˘X-Kť4¤ß!n¤>üOÚT”·EŔwHß•7Ś"â;DoĽQ^IôŞ.LťT §!â©)R“‡„cŔǀۀĄ‰s‘Š¶ř ŕ% |˛äsJ*ĆZ`%.u(sHx1oĺŢVRs#ćł.ăde¬…Dö¦f©yv Ŕ źĎ*kHřeŕú’Î%©\K§ď|żč•ŃĂşŠŘŚ/ő"UIĹ™"6ýŰRäIŠ.XŔωů+IÍö0đv`˛¨=$ĽřË‚Ď!©Î^¤ŔUđEö°–Ź ň!Ňč8Ľxľ9ŻôĎX¬¤Qł¸ö QTëZ`SÇ—T]ÓŔFŕŢĽ\DA™ü‚¸«[Ňhú%đVŕ•<ZĤűßRŔq%ŐÇRŕ·Ä’¦ÜäÝĂ:Ź¨¬ŻÍů¸’ęç·ÄHëŮĽ÷¤ű±XI Ż%jBnňěa˝‡xđ˘$µ»řQĘ«`Ť7@ş?»¤Ůž"6>ö@y oÁb%©ł ‰1´ĂCtÁ$© ž%özN-XK™µćA’*`qoó)CÂËŇä"I=ť¨Míë- ‘¤ąś¨Mö°$Uť=,Iµq˘6ÍLşO‡3“¤#IÝÎ&gzX«±XIަ3‰ubHř¦tąHŇśŢ' ÖŞ„‰HŇ\VÁÉ‚uAş<$iN€=,Iő`KRm\'—5ĽD|m(IUtX8śCëĆBIŞ°Ąă´mÝ Ivţ8đúÔYHRŻ–¤ÎB’2X2NĚaIRŐťcKR],±`IŞ ‡„’jĂ!ˇ¤ÚX2Ľ.u’”ÁëĆ©ł¤ X°$ŐĹ‚q`~ę,$)ů,Iu1ß!ˇ¤şpH(©6揯Ď%”¤*›źűo$©Ćă©“¤ ŽŹ/§ÎB’2xŮ–¤ş°‡%©6^¶`IŞ ‡„’jă¸KR]¦ÎB’288ěOť…$e°x1u’”Á‹ö°$ŐĹ~ –¤şpH(©6JŞŤýăŔŢÔYHR{Ç'?ż:IšĂұÖ/g§ĚD’z8 ,śŮqô鄉HŇ\ž†ŘqôÄ?$©˘ž†“kwş<$iN»Á–¤zxěaIއSzXżJ$ÍĺW3Ë&Ż ĎL–Ž$uv”XvuâAŞ“ŔötůHRWۉEű“źM“‹$őt˘6µ¬G$"Is9Q›ěaIŞşµi¬í\ ě+?Ięi­ Ú{X/Ď&IG’:{–¶ÝdĆgýrsąąHRO§Ô¤ŮkS‰‰HŇ\N©Icł~ůJŞŽó€_Ďücvë×ŔÎRÓ‘¤ÎvŇV¬ŕô‚ %UĂiµ¨SÁrâ]RśV‹fĎaA¬yxľËď$© ÓŔrf­ íÔĂÚ‡7BKJk;˛w*Xŕ<–¤´:Ö nËy,I)u¬AÝć©Ëá' KG’:›$îm>0űÝzX€‡‹ĚH’şxĹ ş,pX()Ť®µ§WÁş§€D$i.]kOŻµVŻž#ÖeIRö+€W;ý˛WëUŕ¶"2’¤.nŁK±‚Ţ ŕkůć"I=ő¬9Ynży X›O.’ÔŐvŕÍ˝ţ`®Ŕć“‹$ő4g­ÉŇĂZ ÇĹ ňYü9AlIÇ’ÔLŹłÉ|ß`'yěÓ> |>‡ăHj®Ď3d±‚ünŻ'nŠľ0§ăIjŽ§›ś§†=P^O™nÍéX’šĺVr(V~„;9H:ŐťDmČEŢ;.śüxmÎÇ•T?ż.žÍë€y¨ĺ1±v]ÎÇ•T?ź~ç‹ŘÓj±ôŇŽ-©~I,}%ĎńřůW€Ź0ä1Iµ5MÔ€\‹S° ¶ŹřfAÇ–Tmߤ í§ŠÜćx9°XTŕ9$UË!ŕŤŔóE<ďI÷vGo ŢSŕ9$UË'MEĽčIL?®(ř<’Ň{x;9Ü‚ÓMQsX3&ż&§U®’*kŠ¸Ö +VP|Á‚Ř•ô«%śGR:_%®őB•őlÁ…Äł ×”t>IĺŮIĽBާ€uÄ ÎI¤Ăjw糤:™·JV¬ ÝV»˙%&ďÜŐAŞ®ŹßMťDę!a»;€÷ĄNBŇiîţ(uP­‚5ř>ŔBŞ’{»S^NťT«`ś l&¤IJë!`p8u"3ŞV°–÷ăÎRJ;«}©iWĹ‚° x87u"ŇÚ¬v§Nd¶ÔËşŮM|kô+Ti"®˝Ę+¨nÁŘü!îˇ%•ĺqÍmKťH7U.X÷JÁűDKb’¸ÖîKťH/UX8:—Äć7ĄNDj°ßHťÄ\ęP° ľ^ť"ľb•”ŻĎ_LťDu)X?–ďHťÔ ˙ üCę$˛ŞSÁ¸ XAÜ1.i8_>L§N$«ş¬ibĂ{‡‡Ňp>|‚+¨_ÁšńSbqŰŤT˙›N©J&‰ öZĚYÍVŐ•îYÝ |8#u"R #–.$ß&fPu/X×űK/JťTa‡Eˇ•^g5—&,€Ë὇R'{Űm*»‚=«¦,¦ďĆ]¤v;¨č˝ýjŇ„őnb;Ś‡R'"UÄCÄ5ŃbÍ*X{÷l vI”FŮ=ĵP©ý¬†Ő´‚±;âŤŔ÷R'"%ň=â¨ĚNˇyibÁxx/đ7ř1ŤŽăD›/q 4N“&Ý»ąř>¬UÍöńÜŔS'R¤¦ö°Ú=HÜ{x{ęD¤‚ÜN´ńF«Qt+±ÚwÚ0Ç6=2FaH8Ű:b¸:u"Ňž$†€[S'R¦Qζ•xîá·S'" čŰD©bĄ¸ký(é»ö†‘%ŽmV#ě ŕ Ň7FĂčOmUbđYbcŔÔ Ó0ÚcŠh›ófąŠHÝH cšh‹W!ő0|8HúkŚf$Ú`]wVËŻă0Ń(/¦6·i@×ŰIߍfÇv˘­IC›| 8Bú†m4+ŽmËIuĺî<ŕŇ7rŁqѦ¤Bmv‘ľÁőŚ]D’J3ř °ô€QŹŘA´‡Jf‚¸ ué/Łš±Ťh#.SPeŚ7[HŐ-D›Ĺ]QT#×›IÁib3ѤZYüźŽBLµ>ëőH57łEó$é/,#ßääĹRŁ\ |ŘKú Í.ö¶>Ë‹‘n¸řńě¸Ôź‘-·>łëń?Ť¨ł€[€㱊1Ůúlni}V’ZV÷•=Fú uÔă±Ög±˛ç'& IÜ/á|W™±·őßÜ ôŠrA[őŤ7÷žm .¦Q|ÚQ¦]=7›€»‰ÂĄŠ˛`ŐĎbŕ˘xmÖâçŐ4±ďÔ&˘HÝHš‘úbCŻżeDńš)`kҦS9;9Y 6űҦŁaX°šgđ.˘x] śź4›ň=ÜK©źĎ%ÍFą˛`5ßRŕ2ŕ-mŻk3S&•ŁÄđîQŕ‘¶×R&ĄbY°FÓ±Bűŕ"ŕ`Uëu5Ő)fG'§Ý­×]Ŕăś|ř­FKťśCĚ…-–´ţ˝dÖĎ‹€3€ŔüV,h{' ÎËŔńÖëĚĎÇ€CŔ~ŕĹÖkűĎą§‹ţ?ŞzůK¸„ˇ8eÇIEND®B`‚mlt-7.32.0/demo/circle.svg000664 000000 000000 00000000125 15006761523 015270 0ustar00rootroot000000 000000 mlt-7.32.0/demo/consumers.ini000664 000000 000000 00000000376 15006761523 016035 0ustar00rootroot000000 000000 SDL Default sdl2 SDL Half D1 sdl2:360x288 rescale=nearest resize=1 SDL High Latency sdl2 buffer=12 rescale=none SDL Progressive sdl2 progressive=1 XML to Terminal xml XML to File xml: DeckLink decklink DeckLink Prog LL decklink progressive=1 buffer=1 mlt-7.32.0/demo/demo000775 000000 000000 00000004020 15006761523 014156 0ustar00rootroot000000 000000 #!/bin/bash export MLT_PROFILE=dv_ntsc export LC_NUMERIC=C function show_consumers( ) { awk -F '\t' '{ printf( "%d. %s\n", ++ i, $1 ); }' < consumers.ini } function get_consumer( ) { option=$1 [ "$option" != "" ] && [ $option -gt 0 ] && sed 's/\t\+/\t/g' < consumers.ini | cut -f 2 | head -n $option | tail -n -1 } function show_menu( ) { sed 's/\t\+/\t/g' < demo.ini | awk -F '\t' '{ printf( "%2d. %-30.30s", ++ i, $2 ); if ( i % 2 == 0 ) printf( "\n" ); } END { if ( i % 2 == 1 ) printf( "\n" ); }' } function check_dependencies( ) { option=$1 if [ $option -gt 0 ] then deps=`sed 's/\t\+/\t/g' < demo.ini | cut -f 3 | head -n $option | tail -n -1` if [ "$deps" != "" ] then echo "$deps" | tr ',' '\n' | while read dep do ls $dep > /dev/null 2>&1 val=$?

 * Special case here: The multitrack must be used in a conjunction with a downstream
 * tractor-type service, ie:
 *
 * Producer1 \
 * Producer2 - multitrack - { filters/transitions } - tractor - consumer
 * Producer3 /
 *
 * The get_frame of a tractor pulls frames from it's connected service on all tracks and
 * will terminate as soon as it receives a test card with a last_track property. The
 * important case here is that the mulitrack does not move to the next frame until all
 * tracks have been pulled.
 *
 * Reasoning: In order to seek on a network such as above, the multitrack needs to ensure
 * that all producers are positioned on the same frame. It uses the 'last track' logic
 * to determine when to move to the next frame.
 *
 * Flaw: if a transition is configured to read from a b-track which happens to trigger
 * the last frame logic (ie: it's configured incorrectly), then things are going to go
 * out of sync.
 *

The logic is complex here. A transition is typically applied to frames on the a and b tracks specified in the connect method above and only if both contain valid info for the transition type (this is either audio or image). However, the fixed a_track may not always contain data of the correct type, eg: 
	+---------+                               +-------+
	|c1       |                               |c5     | <-- A(0,1) <-- B(0,2) <-- get frame
	+---------+                     +---------+-+-----+        |          |
	                                |c4         |       <------+          |
	         +----------+-----------+-+---------+                         |
	         |c2        |c3           |                 <-----------------+
	         +----------+-------------+
During the overlap of c1 and c2, there is nothing for the A transition to do, so this results in a no operation, but B is triggered. During the overlap of c2 and c3, again, the A transition is inactive and because the B transition is pointing at track 0, it too would be inactive. This isn't an ideal situation - it's better if the B transition simply treats the frames from c3 as though they're the a track. For this to work, we cache all frames coming from all tracks between the a and b tracks. Before we process, we determine that the b frame contains something of the right type and then we determine which frame to use as the a frame (selecting a matching frame from a_track to b_track - 1). If both frames contain data of the correct type, we process the transition. This method is invoked for each track and we return the cached frames as needed. We clear the cache only when the requested frame is flagged as a 'last_track' frame. * \private \memberof mlt_transition_s * \param service a service * \param[out] frame a frame by reference * \param index 0-based track index * \return true on error */ static int transition_get_frame(mlt_service service, mlt_frame_ptr frame, int index) { int error = 0; mlt_transition self = service->child; mlt_properties properties = MLT_TRANSITION_PROPERTIES(self); int accepts_blanks = mlt_properties_get_int(properties, "accepts_blanks"); int a_track = mlt_properties_get_int(properties, "a_track"); int b_track = mlt_properties_get_int(properties, "b_track"); mlt_position in = mlt_properties_get_position(properties, "in"); mlt_position out = mlt_properties_get_position(properties, "out"); int always_active = mlt_properties_get_int(properties, "always_active"); int type = mlt_properties_get_int(properties, "_transition_type"); int reverse_order = 0; // Ensure that we have the correct order if (a_track > b_track) { reverse_order = 1; a_track = b_track; b_track = mlt_properties_get_int(properties, "a_track"); } a_track = a_track < 0 ?

You can get a lot of information about how to encode with FFmpeg all over the web including FFmpeg's web site. With melt, you simply need to add "-consumer avformat:output.file" to the command line followed by the encoding parameters by translating ffmpeg's '-option value' syntax to melt's 'option=value' syntax. Not all ffmpeg options are supported. Some are very specific to avconv/ffmpeg, the command line utility, and not an "AVOption" used in the libraries. In some cases, there are ffmpeg options that are not AVOptions but which closely resemble an existing MLT property. In that case, MLT supports the ffmpeg option name. For example, ffmpeg's "-ac" is equivalent to the MLT "channels" property. Therefore, the avformat consumer also supports the "ac" property. Complete details are below. Please note that the exact options depend on the version of libavformat and libavcodec on your system.

and/or video file using FFmpeg. notes: > This is basically the same as the avformat producer, but it does not validate that FFmpeg can open and read the resource. This is primarily useful in a composition (e.g. XML) that was constructed after it was validated. Since validation also determines the length property, you should set that yourself on this producer after having learned it from the normal avformat producer.

Not only does it save on RAM usage, but kernels enforce maximum open file handles and threads per process. Without caching, large projects could easily run into these limits. The default producer cache size is in mlt_cache at size 4. When using mlt_multitrack, the size is adjusted automatically to be the number of tracks plus one if at least 4. This makes it rather dynamic and automatic; however, there are some service graph configurations or authoring scenarios that do not exclusively use the multitrack for multi-layer operations and may need a larger avformat producer cache size. One can set the environment variable MLT_AVFORMAT_PRODUCER_CACHE to a number to override and increase the size of this cache (or to lower it for limited use cases and seeking to minimize RAM). One can set the environment variables MLT_AVFORMAT_HWACCEL and MLT_AVFORMAT_HWACCEL_DEVICE to affect the usage of hwaccel decoding globally. Hardware decoding gracefully falls back to software decoding. bugs: - Audio sync discrepancy with some content. - Not all libavformat supported formats are seekable. - > Seeking is not always accurate.

If you set the property meta.swap_fields=1 on the producer, then this filter swaps the fields of an interlaced frame in addition to any field order correction by shifting the image. mlt-7.32.0/src/modules/core/filter_gamma.c000664 000000 000000 00000005440 15006761523 020351 0ustar00rootroot000000 000000 /* * filter_gamma.c -- gamma filter * Copyright (C) 2003-2014 Meltytech, LLC * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public * License as published by the Free Software Foundation; either * version 2.1 of the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The encapsulated producer can be modified to change the speed (faster/slower) or direction (forward/reverse) In addition to the parameters listed below, this producer inherits all parameters of the encapsulated producer. The encapsulated producer parameters can be accessed directly (without any prefix) by getting and setting those parameters on the timewarp producer. In addition to modifying the speed of the video, the audio is also slowed down or sped up to match the video. parameters: - identifier: resource title: Speed and Resource type: string argument: yes description: | The speed factor and the producer resource in the form: [speed:resource] The speed can be any decimal number between 20 and 0.01. Negative speed values cause the file to be played backwards. The resource can be a file name or any producer service name. The resource will be passed to the loader to create the encapsulated producer. Examples: File opened for 2x speed forward: "2.0:example.mp4" File opened for 2x speed reverse: "-2.0:example.mp4" File opened for 1x speed reverse: "-1.0:example.mp4" File opened for 0.25x speed (slow motion) forward: "0.25:example.mp4" The most common use for this producer is to change the speed of a file.

The value 1 enables the internal keyer, the value 2 enables the external keyer, and the value 0 disables it. readonly: no required: no mutable: no default: 0 minimum: 0 maximum: 2 - identifier: keyer_level title: Key Opacity type: float description: > This controls the level of blending between the key and the input video. 1 is fully opaque and something near 0 is transparent.

If the filename begins with "+" the pango producer interprets the filename as pango text. This is a shortcut to embed titles in melt commands. For MLT XML, it is recommended that you embed the title text in the property value. Pango has builtin scaling. It will rescale the originally rendered title to whatever the consumer requests. Therefore, it will lose its aspect ratio if so requested, and it is up to the consumer to request a proper width and height that maintains the image aspect. Environment variable MLT_PANGO_PRODUCER_CACHE could be used to override and increase the size of cached converted images of simultaneous use. Fontset used by pango producer loaded once. That behavior prevents using new fonts till process used pango producer been restarted. To force fontmap reload you need to send signal "fontmap-reload" to pango producer: { mlt_profile profile = mlt_profile_init("dv_pal"); mlt_producer producer = mlt_factory_producer(profile, "pango", NULL); mlt_events_fire(mlt_producer_properties(producer), "fontmap-reload", NULL ); mlt_producer_close(producer); mlt_profile_close(profile); }; parameters: - identifier: resource title: File type: string description: | A text file containing Pango markup, see: https://developer.gnome.org/pango/stable/PangoMarkupFormat.html requires xml-like encoding special chars from: <, >, & -to- <, >, & readonly: no argument: yes mutable: no widget: fileopen - identifier: markup title: Markup type: string description: | A string containing Pango markup see: http://developer.gnome.org/doc/API/2.0/pango/PangoMarkupFormat.html requires xml-like encoding special chars from: <, >, & -to- <, >, & readonly: no argument: yes mutable: yes widget: textbox - identifier: fgcolour title: Foreground color type: string description: > A color value is a hexadecimal representation of RGB plus alpha channel as 0xrrggbbaa.

Mathematically speaking, it is a bit unusual to look at gamma as a color, but it works pretty well in practice. The classic formula is: output = (gain * (x + lift * (1-x)))^(1/gamma). The lift is actually a case where we actually would _not_ want linear light; since black by definition becomes equal to the lift color, we want lift to be pretty close to black, but in linear light that means lift affects the rest of the curve relatively little. Thus, we actually convert to gamma 2.2 before lift, and then back again afterwards.

First pass performs analysis and stores the result in a property. Parallel processing (real_time < -1 or > 1) is not supported for the first pass. Second pass simply applies the results to the image. If no analysis result is found, the filter does its best to work in real time. To analyse clip, you can use with melt, use 'melt ... -consumer xml:output.mlt all=1 real_time=-1'. Analysis data is stored in a "results" property. For the second pass, you can use output.mlt as the input. parameters: - identifier: rect title: Target Rect type: string description: > The rectangle defining the object to be followed (from the 1st frame of the filter). required: no readonly: no mutable: yes default: 0 0 50 50 - identifier: shape title: Shape type: integer description: > The shape to be drawn around tracked object. 0 for a rectangle, 1 for an ellipse, 2 for an arrow. readonly: no required: no minimum: 0 maximum: 5 default: 0 mutable: yes - identifier: shape_width title: Shape Width type: integer description: > Decide if we want to display a shape around followed object during playback. 0 means no display, -1 means a filled shape and > 0 determines the border width. readonly: no required: no minimum: -1 maximum: 100 default: 1 mutable: yes - identifier: shape_color title: Shape Color type: color description: > The color used to paint the shape around target object. readonly: no required: no default: 0xffffffff mutable: yes - identifier: blur title: Blur type: integer description: > Decide if we want to blur selected object. 0 means no blur, > 0 means blur intensity. readonly: no required: no minimum: 0 maximum: 100 default: 0 mutable: yes - identifier: blur_type title: Blur Type type: integer description: > Decide which blur method is used. 0 for median blur, 1 for gaussian blur, 2 for pixelate, 3 for opaque fill. readonly: no required: no minimum: 0 maximum: 100 default: 0 mutable: yes - identifier: algo title: Tracker Algorithm type: string description: > The algorithm used for tracking (OpenCV name).

The elements * are singly linked for minimum space and pointer manipulation overhead at * the expense of O(n) removal for arbitrary elements. New elements can be * added to the list after an existing element or at the head of the list. * Elements being removed from the head of the list should use the explicit * macro for this purpose for optimum efficiency. A singly-linked list may * only be traversed in the forward direction. Singly-linked lists are ideal * for applications with large datasets and few or no removals or for * implementing a LIFO queue. * * A singly-linked tail queue is headed by a pair of pointers, one to the * head of the list and the other to the tail of the list. The elements are * singly linked for minimum space and pointer manipulation overhead at the * expense of O(n) removal for arbitrary elements.

The elements are doubly linked * so that an arbitrary element can be removed without a need to * traverse the list.

Mathematically speaking, it is a bit unusual to look at gamma as a color, but it works pretty well in practice. The classic formula is: output = (gain * (x + lift * (1-x)))^(1/gamma). The lift is a case where we actually would _not_ want linear light; since black by definition becomes equal to the lift color, we want lift to be pretty close to black, but in linear light that means lift affects the rest of the curve relatively little.

While some avformat properties can accept a "k" suffix, this consumer requires "muxrate" but does not understand the "k" suffix; so, specify the value in bytes per second. The stream is always output to STDOUT at this time. You can rewrite and insert table sections into the transport stream. If you choose to rewrite the PMT sections, then you need to know how libavformat sets the PIDs on the elementary streams. Currently, the video stream is 256 (0x100) and audio streams start at 257, incrementing from there. There are conventions for property names to pass the .sec files to the consumer. The conventions are: si.
.file= si.
.pid= si.
.time=
is really anything, but typically: pat, sdt, nit, eit, etc. "pat," "pmt," and "sdt" are special such that when supplied, they cause libavformat's corresponding sections to be filtered out and replaced with yours. You should always use PID 16 for NIT, 17 for SDT, and of course, 0 for PAT; PMT may be anything, but libavformat uses 4095 (0xfff).

If a keyword can't produce valid data it will print "--". Keywords returning numeric values can use the extra word "decimals" to forcefully set a specific number of decimals (0-9). Example: #gps_speed decimals 3#. Time-based keywords can include a strftime format string to customize the output and a number (representing seconds) preceeded by '+' or '-' which will offset the actual time. For example, "#gps_datetime_now %I:%M:%S %p +3600#" shows only the time in 12-hour format, offset by 1 hour. The speed keyword can have an extra "vertical" or "3D" word as a format to show vertical speed, and 3D speed (takes into account altitude). Speed and distance keywords may include an extra format keyword to convert the value to metric/imperial units. Default is meters and km/h respectively. Supported formats, distance: m|meter, km|kilometer*, mi|mile*, ft|feet, nm|nautical*; speed: ms|m/s|meter, km|km/h|kilo, mi|mi/h|mile, ft|ft/s|feet, kn|nm/h|knots, mmin|m/min, ftmin|ft/min. Computed values are calculated since beginning of GPS file or since "gps_processing_start_time" property, if set.

The following flags can be OR'ed together to allow a client to make changes to the default stream behavior: - \e RTAUDIO_NONINTERLEAVED: Use non-interleaved buffers (default = interleaved). - \e RTAUDIO_MINIMIZE_LATENCY: Attempt to set stream parameters for lowest possible latency. - \e RTAUDIO_HOG_DEVICE: Attempt grab device for exclusive use. - \e RTAUDIO_ALSA_USE_DEFAULT: Use the "default" PCM device (ALSA only). - \e RTAUDIO_JACK_DONT_CONNECT: Do not automatically connect ports (JACK only). By default, RtAudio streams pass and receive audio data from the client in an interleaved format. By passing the RTAUDIO_NONINTERLEAVED flag to the openStream() function, audio data will instead be presented in non-interleaved buffers. In this case, each buffer argument in the RtAudioCallback function will point to a single array of data, with \c nFrames samples for each channel concatenated back-to-back. For example, the first sample of data for the second channel would be located at index \c nFrames (assuming the \c buffer pointer was recast to the correct data type for the stream). Certain audio APIs offer a number of parameters that influence the I/O latency of a stream. By default, RtAudio will attempt to set these parameters internally for robust (glitch-free) performance (though some APIs, like Windows DirectSound, make this difficult). By passing the RTAUDIO_MINIMIZE_LATENCY flag to the openStream() function, internal stream settings will be influenced in an attempt to minimize stream latency, though possibly at the expense of stream performance. If the RTAUDIO_HOG_DEVICE flag is set, RtAudio will attempt to open the input and/or output stream device(s) for exclusive use. Note that this is not possible with all supported audio APIs. If the RTAUDIO_SCHEDULE_REALTIME flag is set, RtAudio will attempt to select realtime scheduling (round-robin) for the callback thread. If the RTAUDIO_ALSA_USE_DEFAULT flag is set, RtAudio will attempt to open the "default" PCM device when using the ALSA API. Note that this will override any specified input or output device id. If the RTAUDIO_JACK_DONT_CONNECT flag is set, RtAudio will not attempt to automatically connect the ports of the client to the audio device. */ typedef unsigned int RtAudioStreamFlags; static const RtAudioStreamFlags RTAUDIO_NONINTERLEAVED = 0x1; // Use non-interleaved buffers (default = interleaved). static const RtAudioStreamFlags RTAUDIO_MINIMIZE_LATENCY = 0x2; // Attempt to set stream parameters for lowest possible latency. static const RtAudioStreamFlags RTAUDIO_HOG_DEVICE = 0x4; // Attempt grab device and prevent use by others. static const RtAudioStreamFlags RTAUDIO_SCHEDULE_REALTIME = 0x8; // Try to select realtime scheduling for callback thread. static const RtAudioStreamFlags RTAUDIO_ALSA_USE_DEFAULT = 0x10; // Use the "default" PCM device (ALSA only). static const RtAudioStreamFlags RTAUDIO_JACK_DONT_CONNECT = 0x20; // Do not automatically connect ports (JACK only). /*! \typedef typedef unsigned long RtAudioStreamStatus; \brief RtAudio stream status (over- or underflow) flags.
