The old API is available as `make_with_name()`. - Builders for `Bin` and `Pipeline` as well as a `Default` trait implementation to simplify object construction. - Builders for `appsrc` and `appsink`, which allow type-safe construction of both elements while also allowing to easily set all their properties at construction time. - Builders for the GStreamer-specific fraction/array param/property specs. - Infrastructure for casting between `gst::Memory` subtypes/supertypes, and make use of it for GL memory. - Bindings for the `gstreamer-allocator` library with support for file descriptor-based and DMABUF memory. - Complete bindings for `gst_video` `Navigation` events. - Constructors for error/warning/info messages with a pre-built `glib::Error`. This also leads to some minor simplification of the existing API. - Accessors for static pads of various base classes for making accessing them cheaper and less error-prone than getting them by name. - Builder for pad templates. - Static PTP clock API for statistics, initialization and deinitialization. - New `gstreamer-utils` crate that currently contains only a `StreamProducer` API. This allows building 1:N bridges between live pipelines via `appsink` / `appsrc` elements. - Bindings for the new `gstreamer-play` library that was added in 1.20. - `gst::Caps::new_empty_simple()` to create caps without fields and just a name. - `gst_audio::AudioCapsBuilder` and `gst_video::VideoCapsBuilder` for building (possibly) unfixed raw audio/videos caps with typed setters for the various fields. This makes it impossible to mix up types and e.g. use an `u32` instead of an `i32` for the width of video caps. - `gst::Buffer::ptr_eq()` to compare buffers by pointer instead of doing a deep comparison, and also `ptr_eq()` on all other miniobject types. - Accessors for `gst_webrtc::WebRTCICECandidateStats` fields. - Bindings for the `gstreamer-validate` API. - Subclassing bindings for `gst_audio::AudioVisualizer` base class for easily writing audio visualization elements. - `gst_pbutils::EncodingProfile` API for element properties. - Support for returning buffer lists from `BaseSrc` / `PushSrc` subclasses. - Support for implementing `gst::Bin::do_latency()`. - Minimal bindings for the `gstreamer-mpegts` library. ### Fixed - Signature for `gst_base::Aggregator::connect_samples_selected()` to remove unnecessary generic parameter and make it straightforward to use. - Various APIs had optional parameters/return types corrected to match the C API more closely. - Logging does not evaluate its arguments anymore if the debug category is not enabled or below the current threshold. - Registering custom metas is now possible without transform function. - `gst::subclass::ElementImpl::request_new_pad()` signature uses a `&str` instead of an owned `String` now. ### Removed - `fragile` dependency and instead use the same functionality from `glib`. - `gst_audio::AudioAggregator` `ignore_inactive_pads` property, which was duplicated from the `Aggregator` base class. ### Changed - Compatible with the 0.16 gtk-rs release. - Updated minimum supported GStreamer version from 1.8 to 1.14. - Updated to the latest GStreamer 1.22 APIs while still supporting up to GStreamer 1.14. Any new 1.22 APIs might still change until the stable 1.22 release. - Updated minimum supported Rust version to 1.63. - In `EventView` / `QueryView`, getters that return references now return references that can outlive the view and are only bound by the lifetime of the corresponding event/query. - In addition `Query`, `Event` and `Message` views are implemented more consistently now, which makes them easier to use and as a side effect allows to pass e.g. more strongly typed queries to functions that only accept a single query type. - Various improvements to `gst::ClockTime`, `gst::format::Bytes`, `gst::format::Signed` and related types and their usage in the API, which should make its use from applications easier and less error-prone. Check the `gst::format` module-level documentation for details. - `gst::StreamsSelected` event builder takes the selected streams as iterator instead of slice. - For consistency with other macros the `gst` prefix of the logging macros was also removed. - Various iterator implementations were added and the existing ones were optimized by implementing more specialized traits and custom implementations for a couple of iterator functions. - GStreamer initialization safety checks were optimized. - `gst::Bus::post()` takes ownership of the passed messages like the C API. - Better and easier to read `Debug` impls for `Caps`, `TagList`, `Structure` and `Promise`. - `ser_de` feature was renamed to `serde`. - `gst::Tracer` implementations get result enums passed as `Result`s now instead of single enums. - `gst::Pad`, `ProxyPad`, `GhostPad` default functions are all associated functions instead of methods now to avoid conflicts between multiple types with the same method. - `Pad` tasks are catching panics from the task function and if the parent of the pad is an element then the panic is converted into an error message and the task is simply stopped. Otherwise the panic is rethrown. ## [0.18.8] - 2022-04-26 ### Added - Bindings for `RTPBasePayload` and `RTPBaseDepayload`. - Accessors for `RTPBuffer` buffer. - Bindings for `RTPBuffer` length calculation API. - More complete `gst::Task` bindings. ### Fixed - Export `gst::subclass::TaskPoolFunction`. ## [0.18.7] - 2022-04-04 ### Added - Bindings for `VideoAggregator` and the `VideoAggregatorPad`s. - Bindings for `AudioAggregator` and the `AudioAggregatorPad`s. - Bindings for `TaskPool`. - Various helper functions for `VideoFormatInfo`, `VideoInfo` and `VideoFrame`. ## [0.18.6] - 2022-03-08 ### Fixed - Require `Send` and not `Sync` for the values of an `gst::Array` / `gst::List`. ### Changed - Simplify and speed up log message string construction ## [0.18.5] - 2022-02-20 ### Changed - Require GStreamer 1.20.0 at least when building with `v1_20`. Earlier versions were already going to fail due to API mismatches before. ### Added - `gst::BufferPool` subclassing support. - `Debug` impl for `gst::MiniObject`. - `gst_rtsp_server::RTSPOnvifServer` and related API, including subclassing support. ### Fixed - Handle empty slices correctly at the FFI layer. - `MiniObjectRef::downcast_ref()` and similar functions return the correct type now. While this is an API change, the previous API would've never worked. ## [0.18.4] - 2022-02-04 ### Changed - Update gir files to GStreamer 1.20.0 release. ### Added - `gst_video::VideoCodecFrame::input_buffer_owned()` for getting an owned reference. ### Fixed - All documentation links in the `README.md`s are correct again. ## [0.18.3] - 2022-01-31 ### Added - `Default` implementation for `gst_video::VideoOverlayComposition` when targeting GStreamer 1.20. - `gst_video::VideoOverlayComposition::add_rectangle()` in addition to the addition of all rectangles via an iterator during construction. - Subclassing support for `gst_rtp::RTPHeaderExtension`. - `gst_webrtc::WebRTCError` for programmatically handling WebRTC errors. ### Fixed - `gst_rtp::RTPHeaderExtension` has `gst::Element` set as parent class now. - Global functions are re-exported from the `gst_rtp` crate root. ### Changed - GIO-style async operations in GES no longer need `Send`-able closures. ### Removed - `fragile` is no longer a dependency and instead the corresponding GLib API is used. ## [0.18.2] - 2022-01-24 ### Added - `glib::FromValue` for mini object references. - Bindings for `gst::DebugCategory::get_line()`. ## [0.18.1] - 2022-01-18 ### Fixed - `Message::view()` also handles the redirect message now. - `Message` and `Query` view variants that return references now borrow again from the underlying query and not the view enum, allowing to use them in a wider scope. ### Changed - All miniobjects, `VideoTimeCode`, `Structure` and `CapsFeatures` are marked as `#[repr(transparent)]` now to ensure that their memory representation is exactly the underlying raw pointer. ## [0.18.0] - 2022-01-16 ### Added - `gst_rtp::RtpHeaderExtension::read()` and `write()`. - `gst::ElementMetadata` has a `const` constructor now. - `gst_rtp::RtpBuffer` API works on buffer references instead of plain buffers for statically enforcing writability and usage in more places. - `gst_video::VideoCodecAlphaMeta` and `gst::CustomMeta`. - `gst::MiniObject` for generically passing around mini objects instead of their concrete types. - `gst_app::AppSink` `new-event` callback and `pull_object()` function. - `gst_pbutils::PbUtilsCapsDescriptionFlags` and `pb_utils_get_caps_description_flags()`. - `gst_rtp::RtpBuffer::remove_extension_data()`. - `gst_video::VideoDecoder` subframe API. - `gst_webrtc::WebRTCSCTPTransport`. - `gst::ElementFactory` `create_with_properties()` / `make_with_properties()`. - `gst_video::VideoContentLightLevel` and `VideoMasteringDisplayInfo` for HDR signalling. - Lots of missing `GES` API. - `gst::AllocationParams` and support in the allocation query. - `propose_allocation()` and `decide_allocation()` support in the various base classes. - `Iterator` implementation for `gst_video::VideoOverlayComposition`. - `Extend`, `IntoIterator` and `FromIterator` implementations for `Buffer`, `Caps`, `BufferList`, `CapsFeatures`, `StreamCollection` and `Structure` for more natural Rust APIs. - `instant-rate-change` events/messages bindings. - Support for arithmetic operations on `Option` and related types. - `gst_video::ColorBalance`. - `gst::MetaFlags`. - `gst_base::Aggregator::set_position()`. - Convenience getters for `gst::ElementFactory` and `gst::DeviceProviderFactory` metadata. - `gst_rtp::RtpBuffer::set_padding()`, `get_padding()` and `payload_mut()`. - `#[must_use]` to many types and functions. - `gst::Event`, `gst::Message` and `gst::Structure` `has_name()`. - `gst_video::Navigation` subclassing support and API improvements. - `gst::Structure` and `gst::Caps` `foreach()`, `map_in_place()` and `filter_map_in_place()`. - `gst_gl::GLBufferPool` and various GL constants and functions. - `gst_pbutils` codec utils APIs. ### Fixed - `gst_base::BaseTransform::prepare_output_buffer()` correctly reflects buffer writability. ### Changed - Compatible with the 0.15 gtk-rs release. - Updated to the latest GStreamer 1.20 APIs while still supporting up to GStreamer 1.8. Any new 1.20 APIs might still change until the stable 1.20 release. - Update all code to the Rust 2021 edition. This causes no user-facing changes. - `gst::Sample::segment()` returns a reference instead of a copy of the segment. - `gst::Object::set_property_from_str()` returns a `Result` now instead of silently failing like the C version. - Allow handling passed in buffers in `gst_base::PushSrc::create`. - Allow passing in `None` in `gst_player::Player::set_uri()`. - Use `[[f32; 4]; 4]` instead of `[f32; 16]` for affine transformation matrix. - `gst::Pad::sticky_event()` statically gets the event of the requested type instead of requiring to match on it afterwards. - Clean up `gst_pbutils` `EncodingProfile` API to be harder to misuse and less confusing. - Various `gst::Array`, `gst::List`, `gst::IntRange` and `gst::Fraction` API improvements that should reduce some friction. - Directly generate `NUL`-terminated C strings in debug log API instead of having multiple allocations per message. - Various functions return `glib::SList` and `glib::List` now to avoid copying into a `Vec` if only iteration is needed. - `gst::ChildProxy` API is more consistent with object property API. - Improved `gst::Buffer::foreach()`, `gst::Pad::sticky_events_foreach()` and `gst::BufferList::foreach()` APIs. - Don't post error messages from `propose_allocation()` and `decide_allocation()`. ## [0.17.4] - 2021-09-13 ### Added - Add constructor for device provider metadata. ## [0.17.3] - 2021-08-23 ### Fixed - `gst::Value::deserialize()` takes the target type as parameter now. This is technically an API change but the function would've never worked previously. ### Added - The release date-time parameter to `gst::plugin_define!` is optional now like in the C version of the macro. - Bindings to `gst::Tracer` and `gst::TracerFactory` for allowing to implement custom tracers in Rust. - Bindings for the new `gst::Value::deserialize_with_psec()` function from GStreamer 1.20. - serde `Serialize`/`Deserialize` impls for `gst::PadDirection`, `gst::PadPresence`, `gst::URIType` and `gst::Rank`. ## [0.17.2] - 2021-08-05 ### Fixed - Various new clippy warnings. - Compilation of `gstreamer-audio` on big-endian platforms. ### Added - Support for 1.20 `Gap` event `GapFlags`. - Support for 1.20 `Structure::serialize()` / `Caps::serialize()`. ## [0.17.1] - 2021-07-13 ### Fixed - Store 1.19 as plugin version when building plugins with `v1_20`. Otherwise plugins fail to load with GStreamer versions below 1.20.0. - Fix documentation for `gst::Element::request_pad_simple()` to actually show up. ## [0.17.0] - 2021-06-28 ### Fixed - Use `#[repr(transparent)]` where it is more correct and remove unneeded `#[repr(C)]` annotations. - Don't provide direct access to the logged object in logging functions as the object might currently be finalized and might be unsafe to access. - Moved X11/EGL/Wayland-specific GL APIs into their own crates instead of having them inside gstreamer-gl and behind feature flags. This simplifies conditional usage of them in applications. - Various nullability issues: parameters and return values that should've been or shouldn't have been nullable were fixed. - Print source object correctly in `gst::Message` `Debug` impl. - `gst_rtsp_server::RTSPServer::attach()` is fallible. - `gst::ElementFactoryListType` is a proper bitflags type now instead of generic `u64`. - `gst::PluginFeature::load()` returns the same type as the one passed in. - Value returned by `gst::PromiseFuture` can no longer be freed while still in scope. - Only assign to `GError**`s in subclassing code if they're not `NULL`. ### Added - Bindings for the GStreamer Controller library and the corresponding core API. - Subclassing support for `gst_player::PlayerVideoRenderer`. - `gst::PARAM_FLAG_CONTROLLABLE` and related bindings. - `gst_video::VideoOrientation` and `VideoOrientationMethod` bindings. - Support for removing pad probes from inside the pad probe callback. - `gst_check::Harness::pull_until_eos()` bindings. - `ges::TransitionClip` and `OperationClip`. - Bindings for `gst_gl::GLMemory` and related APIs. - Subclassing support for `gst_gl::GLFilter` and `gst_gl::BaseSrc`. - `gst::TagList::remove()`. - `gst::CapsFeatures` and `gst::Structure` API based on `glib::Quark`s instead of strings. - Subclassing support for `gst_video::VideoFilter`. - Bindings for various new 1.20 APIs: `gst_app::LeakyType`, `gst_video::VideoDecoderRequestSyncPointFlags`, `gst_rtp::RTPHeaderExtension`, `gst_audio::AudioLevelMeta`, `gst_webrtc::WebRTCKind` and various other new flags/enum types. - Subclassing support for `gst_rtsp_server::RTSPMountPoints`. ### Removed - Deprecated APIs in 0.16. - Don't declare that `gst_app::AppSink` and `AppSrc` inherit from `gst_base::BaseSink` and `BaseSrc` to avoid exposing API that is meant for subclasses to applications. - `gst_app::AppSrc` and `AppSink` signals that are also covered by the callbacks. The callbacks are more flexible and have lower overhead. - Duplicated getters/setters for `gst_base::BaseSink` and `BaseTransform` properties. ### Changed - Compatible with the 0.14 gtk-rs release. - Updated to the new GStreamer 1.20 APIs while still supporting up to GStreamer 1.8. Any new 1.20 APIs might still change until the stable 1.20 release. - FFI and safe high-level bindings are in the same repository now and use the same version numbers. - The .gir files are shared with gtk-rs and the GStreamer-specific ones are in a separate git submodule. - Update all code to the Rust 2018 edition. As part of this, most macros lost their `gst_` prefix. - Re-export dependency crates from the different preludes. - Getter functions don't have a `get_` prefix anymore and GObject property accessors don't include the `_property_` part in the middle of their function names anymore. Applications developers should use [`fix-getters-calls`](https://crates.io/crates/fix-getters-calls) to ease migration of their applications. Use [`fix-getters-def`](https://crates.io/crates/fix-getters-def) if you also want your `get` functions definition to comply with the API standards applied in this release. - Lots of changes to the subclassing API. Check the various elements in [gst-plugins-rs](https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs) for examples. - Major improvements to the documentation infrastructure and generated documentation. - `gst::ClockID` bindings are refactored to use different types for single-shot and periodic clock ids, which makes misuse harder. - `gst::ProxyPad` extension trait uses trait functions instead of associated functions now for usability reasons. - Use `Result` for overriding flow returns from pad probes. - `gst_video::VideoInfo::align()` returns a `Result` instead of a `bool`. - Use actual error types instead of `()` in `gst_sdp` APIs. - `Display` impl for `gst::ClockTime` provides better human-readable strings. - `gst::Element::link_filtered()` and `link_pads_filtered()` takes a non-optional caps now. That's easier to use and for not providing caps the non-filtered variants of the functions exist. - Replace various manual bindings with auto-generated ones. - `gst::Element::get_request_pad()` is replaced by `request_pad_simple()` as a simpler version of `request_pad()` and in accordance with the deprecation in GStreamer 1.20. - `gst::ClockTime` and APIs working on it were changed to make possibility of using `GST_CLOCK_TIME_NONE` expressed in the type system. `Option` can be `None` while `gst::ClockTime` is always a valid time. ## [0.16.7] - 2021-02-13 ### Fixed - Usage of the logging system with a GStreamer library with the logging system compiled out does not crash any longer. - Double-free in `gst_video::VideoTimeCode` API when converting between validated and unvalidated timecodes. ### Added - `gst::Element::get_current_state()` and `get_pending_state()` convenience APIs. - `gst_audio::AudioConverterConfig` for setting the configuration on e.g. the `audiomixer` element. The low-level `AudioConverter` API is still not included in the bindings. ## [0.16.6] - 2020-12-20 ### Fixed - `VideoTimeCodeInterval`'s `Ord` and `PartialEq` implementations compare against the correct fields now. - `SDPMessage::medias_mut()` iterator does not crash any longer. ### Added - `PartialEq` and `Eq` implementations on `VideoAlignment`. - Alignment API for `VideoMeta` and `get_plane_height()` / `get_plane_size()`. - `VideoInfo::align_full()`. ## [0.16.5] - 2020-11-23 ### Fixed - Make sure to use `$crate` in more macros to allow them to work without anything special in scope already. - Update documentation location. - Don't panic if C code stores invalid seqnums in events and the seqnum is used directly or via the `Display` impl. - Fix docs build for some crates on docs.rs. - Fix `Debug` impl for `gst_video::VideoTimeCode` to print the correct type name. - Fix plugin version to be 1.18 instead of 1.17 when compiling a plugin with `v1_18`. ### Added - Event handling support in pad probes, that is returning `PadProbeReturn::Handled` for events. - `EventRef::get_structure_mut()` getter that allows changing the events' structures. ### Changed - Remove unnecessary `PhantomData` markers and use `repr(transparent)` instead of `repr(C)` where it is more correct. ## [0.16.4] - 2020-10-09 ### Fixed - Correctly implement `ExactSizeIterator` on the `AudioFormat` and `VideoFormat` iterators. Previously they returned the overall size instead of the remaining size, and they didn't implement `Iterator::size_hint()`. - Don't implement `ExactSizeIterator` on the buffer `gst::Meta` iterator. The overall length is not known easily and the implementation would've simply panicked in the past. ### Added - `gst::ClockID::wait_async_stream()` for async integration for clock waiting. - `From` / `TryFrom` impls for converting between `gst::ClockTime` and `std::time::Duration`. ## [0.16.3] - 2020-09-08 ### Fixed - Reset vfuncs if calling `BaseTransformClass::configure()` multiple times. - Fix `gst::debug_remove_default_log_function()` to actually remove the default log function. ### Added - Some more new APIs added in 1.18. - API for getting an owned buffer from a readable `gst_video::VideoFrame` / `VideoFrameRef`. ### Changed - Updated bindings to 1.18.0. This stabilized GStreamer 1.18 support and any API behind the "v1_18" feature is considered stable now. - Factor out some common code from `gst::Pad::ProbeInfo` code. This reduces the code generated for each pad probe considerably. - Update paste dependency to 1.0 and pretty-hex to 0.2. ## [0.16.2] - 2020-07-27 ### Fixed - Use correct pointer for the plane data in `gst_audio::AudioBuffer`. ### Added - Add `gst::GhostPad` convenience constructors that take a target pad, similar to the ones that existed in 0.15 and before. - Add `gst::parse_bin_from_description_with_name` that allows setting a name for the created bin without having to use unsafe code in application code. ## [0.16.1] - 2020-07-10 ### Fixed - Allow calling `gst::DebugCategory::new()` before `gst::init()` again. ## [0.16.0] - 2020-07-06 ### Added - Updated bindings to 1.17.2, adding experimental 1.18 support. This can be opted-in via the "v1_18" feature flag but there might still be API changes in the newly added API. - `gst::MemoryRef::dump()` for dumping contents of a memory. - `gst::Bus::stream()` instead of a custom constructor on the `BusStream`. - Use more accurate types for `Seqnum`, `GroupId` and `MetaSeqnum`. These are now proper wrapper types instead of plain integers, which makes misuse harder. - Provide `TryFrom` impls for conversion between `glib::DateTime` and `gst::DateTime`. - Add `get_allocator()` functions to `gst_base::{Aggregator, BaseTransform, BaseSrc}`, and allow overriding `BaseSrc::alloc()`. - Add subclassing bindings for `gst_base::PushSrc`. - Add new `gst::BufferCursor` API that allows to handle a buffer as `Read`, `Write` and `Seek` and accesses the underlying memories of the buffer individually without mapping them all together. - Add `gst::Plugin::get_plugin_name()`. - Support for `gst_video::VideoAFDMeta` and `VideoBarMeta`. - API for getting all / iterating over all `gst_audio::AudioFormat` and `gst_video::VideoFormat`. - Bindings and subclassing bindings for `gst_video::VideoSink`. - `gst::Pad` can be constructed via the builder pattern and `gst::PadBuilder` now, which allows to safely set the pad functions and various other fields during construction. The `PadBuilder` works on any `gst::Pad` subclass and also has special support for `GhostPad`s by allowing to set pad functions of the proxy pad. - `gst::Message`, `gst::Event` and `gst::Query` type constructors are now on the specific target type instead of various `new_XXX()` functions on the basic type. E.g. `gst::message::Eos::new()`. - Support for overriding `gst_audio::AudioSrc/Sink::reset()`. - Support for overriding `gst_base::BaseParse::stop()`. - Support for overriding `gst::Element::post_message()`. - Added bindings for `gst::BufferList::foreach()` and `foreach_mut()`. - Added bindings for `gst::Buffer::foreach_meta()` and `foreach_meta_mut()`. ### Fixed - Allow using any `glib::Object` as target object for logging instead of just `gst::Object`. - Remove restriction API from `gst_pbutils::EncodingContainerProfile`. They are supposed to be used only with the other encoding profiles. - Return `&'static str` for various `gst::StructureRef` functions where the string is backed by a `glib::Quark`. - Fix various `gst::DateTime` functions to actually return `Option`s. - Add support for filling in a buffer passed to the `gst::Pad` getrange function, allow passing one in into `get_range()` and `pull_range()` and provide the corresponding API on `gst_base::BaseSrc` too. - Allocator in audio/video `Decoder` base classes is optional and can return `None`. - `gst_video::ValidVideoTimeCode::add_interval()` always returns a valid timecode again. - Allow resolving a `gst::Promise` with `None` and also handle that correctly in the callback. This is allowed by the API. - Allow calling various debugging related functions before `gst::init()`. - Various enum/function versions were fixed to only show up if the corresponding version feature is enabled. - `gst::Pad` function setters are marked unsafe now as changing the functions is not thread-safe. - Remove `gst::Object::set_name()` as changing the name after construction generally causes problems and is potentially unsafe. - Remove `gst::Pad::set_pad_template()` as changing the pad template after construction is generally unsafe. - `gst::Pad::stream_lock()` borrows the pad now instead of taking a new reference. - Unimplemented `Jitter` and `Buffer` queries were removed from the bindings. These are not implemented in C and only have a type registered. - Various `LAST`, `NONE` variants of enums and flags were removed as these only make sense in C. - Call the parent impl of various vfuncs that were omitted before to not require further subclasses of them to implement them but automatically call the parent ones. ### Changed - Use `NonZeroU64/U32` for various ID types to allow further optimizations. - Use `thiserror` crate for deriving error types. - Switch from `lazy_static` to `once_cell`. - Change various miniobject functions like `gst::Caps::append()` from taking the object by value to modifying it internally. This makes them easier to use and only applies to functions that are defined on the non-reference type and take ownership of the values passed in. - Use `mem::ManuallyDrop` instead of `mem::forget()` everywhere. - Replace most `mem::transmute()` calls with safer alternatives. - `gst:StreamCollection` API was changed to the builder pattern for construction as the collection must not be changed after construction. - `gst::ProxyPad` default functions are plain functions on `ProxyPad` now instead of trait functions to allow easier usage of them. - Use proper error types in various `TryFrom` impls. - `gst_video::VideoMeta::add()` returns a `Result` now instead of panicking. - Various constructors were renamed from `new_with_XXX()` and `new_from_XXX()` to the more idiomatic `with_XXX()` and `from_XXX()`. - Miniobject bindings are simplified now and there is no `gst::GstRc` type anymore, instead everything is directly implemented on the concrete types. As part of this the `gst::MiniObject` trait was also removed as it was unneeded now. ## [0.15.7] - 2020-06-08 ### Fixed - Allow multiple filter types per process with `gst::Iterator::filter()`. - Check that `VideoInfo` is valid when creating a `VideoFrame`. - Don't potentially dereference a `NULL` pointer when getting the format from an invalid `VideoInfo` or `AudioInfo`. - Don't unmap borrowed `VideoFrameRef`s. ### Added - `gst::ProtectionMeta`, `gst_video::VideoAffineTransformationMeta`, `VideoCropMeta` and `VideoRegionOfInterestMeta` bindings. - Various new `gst_rtp::RTPBuffer` methods. - `gst_audio::audio_buffer_truncate()`, `AudioMeta` and `AudioBuffer` bindings. ## [0.15.6] - 2020-05-28 ### Fixed - Assert that the data passed to `VideoCaptionMeta::add()` is not empty. - Don't store strong references to the object in the bus, appsink and appsrc futures `Stream` / `Sink` adapters. This would keep them alive unnecessarily and would prevent the `Stream` / `Sink` to ever "finish" on its own. - Handle receiving a `None` reply in the change function of `gst::Promise`. This is apparently valid. For backwards compatibility reasons this is currently replaced with an empty structure but in 0.16 the API will explicitly handle `None`. ### Added - `gst::Stream::debug()` and `gst::StreamCollection::debug()` for converting into a structured string with the actual contents of each. - `gst::Structure::from_iter()` and `gst::Caps::from_iter()` to create structures/caps from iterators. - `gst::Event` support for getting/setting the `gst::Stream` in the `StreamStart` event. - `gst_video::calculate_display_ratio()` and `::guess_framerate()`. - Various video related `gst::CapsFeatures` in `gst_video`. - `TryFrom`/`From` impls for converting between `gst::Structure` and `gst_video::VideoConverterConfig`. - Various `glib::Value` trait impls for `SDPMessage`, `StructureRef`, `CapsFeatureRef` and all borrowed variants of miniobjects to be able to work with the borrowed, non-owned variants when handling `glib::Value`s. ## [0.15.5] - 2020-05-03 ### Fixed - Revert: Allow logging any `glib::Object` and not just `gst::Object`. This broke API in subtle ways and needs to wait until 0.16 - Replace `%` in log output with `%%` to prevent accidental C formatting - Add missing manual traits to the documentation ### Added - `BufferRef::peek_memory_mut()` to give a mutable reference to a given memory - Different iterators for iterating over the memories of a buffer - Support for `gst_audio::AudioClippingMeta` - `gst::Plugin::get_plugin_name()` was added - `gst::Element::get_current_clock_time()` and `gst::Element::get_current_running_time() helper functions - `gst::State` and `StateChange` API for calculating next/previous state and convert from/to the components of a state change ### Changed - Use `mem::ManuallyDrop` instead of `mem::forget` everywhere ## [0.15.4] - 2020-03-09 ### Fixed - Allow logging any `glib::Object` and not just `gst::Object` - Fix floating reference handling in `RTSPMedia::take_pipeline()` - Hold `GMutex` guards for the remainder of the function and warn if they're directly dropped - Work around empty/any caps handling bugs in `Caps::fixate()` ### Added - Add `BaseTransform::prepare_output_buffer()` subclassing support - `RTSPServer`, `RTSPClient`, `RTSPMedia` and `RTSPMediaFactory` subclassing support - Handle panicking in `appsrc`/`appsink` callbacks by posting an error message instead of killing the process ## [0.15.3] - 2020-02-15 ### Fixed - `UniqueFlowCombiner::clear()` should take a mutable reference. - `AudioStreamAlign` doesn't require mutable references for getters anymore. - Don't use bool return value of `gst_video_info_set_format()` and `gst_video_info_align()` with GStreamer < 1.11.1 as it returned void back then. We'd otherwise use some random value. - Make `VideoInfo::align()` is available since 1.8. - Fix changing/clearing of `AppSrc`, `AppSink` callbacks and `Bus` sync handler. Before 1.16.3 this was not thread-safe and caused crashes. When running with older versions changing them causes a panic now and unsetting the bus sync handler has not effect. With newer versions it works correctly. ### Added - Add `Clone` impls for `BufferPoolConfig` and `PlayerConfig`. - Add `VideoConverter` bindings. - Add `Future`s variant for `gst::Promise` constructor. - Add `Future`s variant for `gst_video::convert_sample_async()`. - Add `submit_input_buffer()`, `generate_output()`, `before_transform()`, `copy_metadata()` and `transform_meta()` virtual method support for `BaseTransform`. - Add `AppSink` `Stream` adapter and `AppSrc` `Sink` adapter for integrating both into Rust async contexts. ### Changed - More generic implementations of `VideoFrame` / `VideoFrameRef` functions to allow usage in more generic contexts. ## [0.15.2] - 2020-01-30 ### Fixed - Fix another race condition in the `gst::Bus` `Stream` that could cause it to not wake up although a message is available. ## [0.15.1] - 2020-01-23 ### Added - Use static inner lifetime for `VideoCodecState` so that it can be stored safely on the heap. - Getters/setters for `BinFlags` on `gst::Bin`. - `gst::Caps::builder_full()` for building caps with multiple structures conveniently. - `gst::Element::call_async_future()` for asynchronously spawning a closure and returning a `Future` for awaiting its return value. ### Fixed - Various clippy warnings. - Getters/setters for `PadFlags` on `gst::Pad` now provide the correct behaviour. - Take mutex before popping messages in the `gst::Bus` `Stream` to close a small race condition that could cause it to not be woken up. - `gst::ChildProxy` implementers do not have to provide `child_added()` and `child_removed()` functions anymore but these are optional now. - Manually implement `Debug` impls for various generic types where to `Debug` impl should not depend on their type parameters also implementing `Debug`. ## [0.15.0] - 2019-12-18 ### Added - `StructureRef::get_optional()` for returning `None` if the field does not exist instead of `Err` - Bindings for `gstreamer-rtp` library, mostly `RTPBuffer` - Support for writing `Preset`, `TagSetter`, `Clock`, `SystemClock` subclasses - Bindings for `Typefind::get_length()` - Bindings for `BaseSrcImpl::get_times()` - Bindings (incl. subclassing) for `AudioSink` and `AudioSrc` - Missing `Send`/`Sync` impl for various types ### Fixed - Cleanup of cargo features/dependencies to improve build times - Serde serialization with optional values. Attention: This changes the format of the serialization! - `VideoEncoder`/`VideoDecoder` `proxy_getcaps()` can't return `None` - Use non-panicking UTF8 conversion in log handler. We don't want to panic just because some C code printed a non-UTF8 string - Re-rexport all traits from the crate level and also ensure that all traits are actually included in the preludes - Actually export `is_video_overlay_prepare_window_handle_message()` function - Use `FnMut` for the `appsink` callbacks instead of `Fn` - `Promise` change function returns the actual reply to the promise now instead of just passing the promise itself - Memory leak in `Iterator::filter()` - `BinImpl::add()` takes ownership of floating references - `DeviceImpl::create_element()` preserves floating flag - `BinImpl::remove()` takes a strong reference of the element now as the last reference might be owned by the bin and otherwise we would potentially have a use-after-free afterwards - `BaseParseFrame` and `VideoCodecFrame` take a `&mut self` now for various functions that actually change the frame ### Changed - Minimum supported Rust version is 1.39 - Allow passing `None` to `VideoEncoder::finish_frame()` - Various `to_string()` methods were moved into the `Display` trait impl and for some types `to_str()` was added to return a `&'static str` - .gir files were updated to 1.16.2 release - `Sample` constructor uses the builder pattern now - `VideoMeta::add_full()` is simplified and requires parameters - `BasetransformImpl::set_caps()` returns a `Result` instead of `bool` - SDP data type getters for strings return an `Option` now as these can be `None` in practice although not allowed by the SDP spec - Various functions returning `Option`s were changed to return `Results` if `None` actually signalled an error instead of just a missing value ### Removed - "subclassing" and "futures" cargo features. These are enabled by default now ## [0.14.5] - 2019-09-17 ### Added - Support subclassing of `gst::Device`, `gst::DeviceProvider`, `gst_audio::AudioDecoder` and `::AudioEncoder` - Support for `Element::set_clock` and `::provide_clock` virtual methods - `ElementClass::add_metadata` was added - `gst_video::VideoDecoder` and `::VideoEncoder` got support for `get_caps`, `negotiate`, `src/sink_query/event` and the `drain` virtual methods - `Element::num_pads`, `::num_src_pads` and `::num_sink_pads` functions - `gst_video::VideoDecoder` and `::VideoEncoder` got `get_allocator` bindings - `gst::Iterator` implements `IntoIterator` now for providing `std::iter::Iterator>` adapter - Error macros for audio/video decoder subclasses to handle decoding errors more gracefully and only actually error out after many consecutive errors ### Fixed - Macros now also work in Rust 2018 edition without `#[macro_use]` but explicit imports - The log handler unit test runs reliable in parallel with other tests - Manually implement `Debug` for `gst::Iterator` to allow it for any `T` instead of `T: Debug` - `Device::create_element` has correct reference count handling now - Return `NotNegotiated` in the video codec base classes if setting the output state fails instead of `Error` ## [0.14.4] - 2019-08-14 ### Added - Bindings for adding/removing custom log functions - Bindings for `calculate_linear_regression()` - Constants for base class custom flow returns ### Fixed - Ownership of pad in `Element::release_pad()` virtual method implementations ## [0.14.3] - 2019-07-16 ### Added - `Buffer::unset_flags()` for unsetting specific buffer flags - `VideoBufferFlags` flags type and `VideoBufferExt::set_video_flags()`, `unset_video_flags()` and `get_video_flags()` for working with video buffer flags from safe code. ### Fixed - Setting buffer flags does not override arbitrary other flags anymore but only sets the flags in question. This is necessary to not override extension buffer flags like `gst_video::VideoBufferFlags`. ## [0.14.2] - 2019-07-15 ### Added - Support for `ReferenceTimestampMeta` ## [0.14.1] - 2019-07-06 ### Added - Various new WebRTC enum types from 1.14.1/1.16.0 ### Fixed - Correctly generate interlaced `VideoInfo` by using `gst_video_info_set_interlaced_format()` instead of the generic function. - serde serialization unit tests for `gst::format` succeed again now. ### Changed - `Debug` impls for `VideoFormatInfo` and `AudioFormatInfo` now print all the details of the format instead of only the name, and the `Debug` impls for `VideoInfo` and `AudioInfo` also print the format now. ## [0.14.0] - 2019-06-24 ### Added - Bindings for `GLSyncMeta`. - Bindings for setting/getting `TagScope` on a `TagList` - Bindings for `GLDisplayWayland` and `GLDisplayX11` in addition to the already existing `GLDisplayEGL` - Bindings for `Bus::pop_filtered()` and related functions - Bindings for getting/setting `Object`, `Element`, `Bin`, `Pipeline` and `Plugin` flags - Bindings for `VideoCaptionMeta` - `Debug` impl of `Buffer` now also shows the metas of the buffers - Expose flow return in `PadProbeInfo` for overriding the return value - Bindings for `VideoDecoder` and `VideoEncoder`, including subclassing support - Bindings for `Memory`, `Allocator` and `VideoBufferPool` - Bindings for `VideoFormatInfo::pack` and `::unpack` for format conversion - Bindings for `BaseParse`, including subclassing support - Various new arithmetic operation impls for fractions, formatted values and `ClockTime` - Bindings for `VideoInfo::align()` ### Changed - The `SDPMessage` and `SDPMedia` bindings were completely rewritten as they were broken before and caused crashes in various usages. As part of this there's also some more convenience API available on these types, like iterators for example, and API to modify the `SDPMedia` contained in a `SDPMessage`. - Update to GStreamer 1.16. - Regenerate with latest gir. - Run all autogenerated code through rustfmt after generation too. - Updated to latest versions of GLib/GIO/etc crates. - Updated to futures 0.3 / `std::future` - `ProxyPad` default functions moved to an extension trait instead of plain functions on `ProxyPad`, making them more in sync with the default `Pad` functions - GStreamer plugins are now exporting the new 1.14+ plugin symbols if they were configured for GStreamer 1.14+ - Arithmetic operations on formatted values and `ClockTime` do overflow checks now and replace the result with the `NONE` value on overflow - `TryFrom`/`TryInto` traits are used in various places now instead of the previous ad-hoc implementations of them. - Registering element/typefind/device monitor factories requires passing a value of `gst::Rank` now instead of an arbitrary `u32` ### Fixed - Use correct type for destroying pad task closure data. This was previously using the wrong type, causing crashes at runtime. - `DeviceAdded`/`DeviceRemoved` message getters are transfer full so we don't need to take an additional reference that would be leaked. - `AppSink` callbacks are correctly marked as `Send` instead of `Send+Sync`, allowing a wider range of closures to be used for them. - Handle `PadProbeReturn::Handled` return values from pad probes more correctly. - `ToOwned::to_owned()` on miniobjects has to create copies instead of only increasing the reference count. Otherwise it was possible to create multiple mutable and immutable references to the same object at the same time. - Various functions take references to owned miniobjects instead of borrowed references as it was otherwise possible to create multiple mutable or immutable references to the same object at the same time. - `URIHandler::set_uri` does not accept `None` anymore as this is not allowed by the C function. - Comparisons and addition of `TypeFindProbability` and `Rank` work correctly now - Various `Display` implementations were fixed to not cause a stack overflow due to infinite recursion anymore - Various `::to_string()` functions don't take ownership of C strings anymore that they do not own, which caused double frees before ### Removed - MIKEY related bindings from the SDP library. The bindings were broken and until someone needs them these are not available anymore. ## [0.13.0] - 2019-02-22 ### Added - Subclassing infrastructure was moved directly into the bindings, making the `gst-plugin` crate deprecated. This involves many API changes but generally cleans up code and makes it more flexible. Take a look at the `gst-plugins-rs` crate for various examples. - Bindings for GStreamer GL library - Bindings for `CapsFeatures` and `Meta` - Bindings for `ParentBufferMeta, `VideoMeta` and `VideoOverlayCompositionMeta` - Bindings for `VideoOverlayComposition` and `VideoOverlayRectangle` - Bindings for `VideoTimeCode` - Bindings for `NetAddressMeta` - Bindings for registering custom tags - `UniqueFlowCombiner` and `UniqueAdapter` wrappers that make use of the Rust compile-time mutability checks and expose more API in a safe way, and as a side-effect implement `Sync` and `Send` now - `Bus::add_watch_local()` and `gst_video::convert_frame_async_local()` that allows to use a closure that does not implement `Send` but can only be called from the thread owning the main context. - More complete bindings for `Allocation` `Query` - `pbutils` functions for codec descriptions - `TagList::iter()` for iterating over all tags while getting a single value per tag. The old `::iter_tag_list()` function was renamed to `::iter_generic()` and still provides access to each value for a tag - `Bus::iter()` and `Bus::iter_timed()` iterators around the corresponding `::pop*()` functions - Getters for `VideoColorimetry` to access its fields - `Debug` impls for various missing types. - serde serialization of `Value` can also handle `Buffer` now - Extensive comments to all examples with explanations - Transmuxing example showing how to use `typefind`, `multiqueue` and dynamic pads - basic-tutorial-12 was ported and added ### Changed - Rust 1.31 is the minimum supported Rust version now - Update to latest gir code generator and glib bindings - Functions returning e.g. `gst::FlowReturn` or other "combined" enums were changed to return split enums like `Result` to allow usage of the standard Rust error handling. - Various functions and callbacks returning `bool` or `Option<_>` were changed to return a `Result<_, glib::BoolError>` or `Result<_, gst::LoggableError>` or `Result<_, gst::ErrorMessage>` for better integration with Rust's error handling infrastructure. - Some infallible functions returning `bool` were changed to return `()`. - `MiniObject` subclasses are now newtype wrappers around the underlying `GstRc` wrapper. This does not change the API in any breaking way for the current usages, but allows `MiniObject`s to also be implemented in other crates and makes sure `rustdoc` places the documentation in the right places. - `BinExt` extension trait was renamed to `GstBinExt` to prevent conflicts with `gtk::Bin` if both are imported - `Buffer::from_slice()` can't possible return `None` ### Fixed - `gst::tag::Album` is the album tag now instead of artist sortname - Return `0` for the channel mask corresponding to negative `AudioChannelPosition`s. - `PartialOrd` and related traits are implemented via pointer equality on `ClockId` instead of using the compare function. Two clock ids with the same timestamp are not necessarily the same. - Various functions that are actually fallible are now returning an `Option<_>`. - Various `clippy` warnings ## [0.12.2] - 2018-11-26 ### Fixed - PTP clock constructor actually creates a PTP instead of NTP clock ### Added - Bindings for GStreamer Editing Services - Bindings for GStreamer Check testing library - Bindings for the encoding profile API (encodebin) - VideoFrame, VideoInfo, AudioInfo, StructureRef implements Send and Sync now - VideoFrame has a function to get the raw FFI pointer - From impls from the Error/Success enums to the combined enums like FlowReturn - Bin-to-dot file functions were added to the Bin trait - gst_base::Adapter implements SendUnique now ### Changed - All references were updated from GitHub to freedesktop.org GitLab - Fix various links in the README.md - Link to the correct location for the documentation - Remove GitLab badge as that only works with gitlab.com currently ## [0.12.1] - 2018-09-21 ### Added - More complete bindings for the gst_video::VideoOverlay interface, especially gst_video::is_video_overlay_prepare_window_handle_message() ## [0.12.0] - 2018-09-08 ### Added - Bindings for the GStreamer SDP and WebRTC libraries - Generic API for working with tags that is based on string tag names and glib::Value for the tag values - Bindings for Aggregator and AggregatorPad - Bindings for BaseTransform/BaseSrc::get_buffer_pool() - Optional serde implementations for the basic GStreamer data flow and metadata types ### Changed - Use ptr::NonNull in various places - Updated to muldiv 0.2, num-rational 0.2 - Bus::create_watch() can't return None - Remove CallbackGuard as unwinding across FFI boundaries is not undefined behaviour anymore but will directly cause a panic - Changed from the futures to the futures-preview crate as an optional dependency - Various Caps operations take a &CapsRef instead of &Caps - "deep-notify" signal takes the whole ParamSpec as parameter instead of only the signal name - Some structs were changed from empty struct to empty enums - Pad probe code does not take an additional reference to the data anymore, potentially passing writable events/buffers into the probe - ValueExt::compare() is implemented around std::cmp::Ordering now instead of a custom enum that was basically the same ### Fixed - Pad::add_probe() can return None if an IDLE probe was already called and removed in the meantime - Various compiler and clippy warnings ### Removed - std::Iterator impl for gst::Iterator. It was awkward to use because the gst::Iterator could fail at each iteration ## [0.11.6] - 2018-08-27 ### Fixed - Build with NLL/two-phase borrows - Explicitly define [bin] section for discoverer example to fix a cargo warning ### Added - Add unsafe gst::deinit() function - Ord/PartialOrd impls on gst::Seqnum - Getter for current pad mode - gst::Pad::sticky_events_foreach() for iterating over all sticky events in a thread-safe way ## [0.11.5] - 2018-07-24 ### Fixed - `gst::Bus`'s sync handler must unref every message if `gst::BusSyncReply::Drop` is returned, otherwise they are all leaked ## [0.11.4] - 2018-07-19 ### Fixed - `gst::Caps::subtract()` does not leak its arguments anymore - `gst::Caps::get_structure()` gracefully returns `None` if the index is out of bounds instead of a `g_return_val_if_fail()` - `gst::Structure::new()` has to give away ownership of the info structure but didn't. For 0.11 we internally copy, in 0.12 it will take the info structure by value - Typefind tests don't fail anymore if the system has typefind factories without caps ### Added - An additional assertion that ensures that miniobjects are actually writable before creating a mutable reference ## [0.11.3] - 2018-06-08 ### Added - `gst::Bus::remove_watch()` is now available to remove a bus watch again - `fmt::Debug` impls for `AudioInfo` and `VideoInfo` were added - `fmt::Debug` impls for mini objects also print the pointer value now to make it easier to track them in debug logs - `PlayerVisualization` has accessors for the name and description fields now, without which there is no sensible way to use them or to set a player visualization ## [0.11.2] - 2018-05-09 ### Fixed - Work-around various floating reference handling changes between 1.12 and 1.14 to be able to run with both versions without memory leaks or other reference count problems. This affects NetTimeProvider, BufferPool, DeviceMonitor, Stream, StreamCollection, and Player, NetClientClock, NetClock, PtpClock which were already previously fixed. ### Changed - Change the appsrc need-data and all appsink callbacks to not require the Sync bound anymore and change from Fn to FnMut. They can only be called from a single thread at a time. This change is only done for the corresponding callbacks, not the signals. ## [0.11.1] - 2018-04-07 ### Fixed - Fix Structure::to_string() to not run into an infinite recursion but call the method on the contained StructureRef instead of on itself ## [0.11.0] - 2018-03-20 ### Changed - Updated everything to GStreamer 1.14.0 - Event, Message and Query types were refactored to improve usability. Especially newly constructed queries allow to directly use the type-specific functions to be used without first creating a view - VideoFrameRef::copy_to_ref() and ::copy_plane_to_ref() are gone now and the original functions work with refs instead of full frames - PadProbeId and NotifyIds are not Copy/Clone anymore and are taken by value - GstPlayer has GstObject as parent class now ### Added - GstPbutils, GstSdp, GstRtsp and GstRtspServer bindings - GstPromise, GstAudioStreamAlign and various other 1.14 API - GstVideoFilter and GstBufferPool bindings - Element::call_async() - Debug impl For Toc and TocEntry - Various new examples (RTP FEC, RTSP server, tag usage, ...) ### Fixed - Memory leak in gst_video::convert_sample_async() ## [0.10.2] - 2018-02-18 ### Fixed - Fix building of messages with custom fields for types that don't have a GstStructure ### Added - VideoFrameRef::copy_to_ref() and ::copy_plane_to_ref(), which work with VideoFrameRefs instead of full VideoFrames - Getters for the BaseSrc/Sink/Transform configured segment - Document the gstreamer-player-1.0 dependency in the README.md ## [0.10.1] - 2018-01-03 ### Fixed - Don't require &mut self for TagSetterExtManual::add() ### Added - A TagSetter example application - Bindings for gst_video::convert_sample() and ::convert_sample_async() - Bindings for gst_video::VideoRectangle - Debug impl for Sample and ::with_buffer_list() constructor - A borrowing version of VideoFrame: VideoFrameRef - Bindings for GstVideoFilter ### Changed - Deprecated Sample::get_info() in favour of ::get_structure() - Player has gst::Object as another parent class now ## [0.10.0] - 2017-12-22 ### Fixed - Various clippy warnings - Memory leak of the tag list in Toc::merge_tags() - Property getters use Values of the correct type - Event::get_structure(), Message::get_structure() and Query::get_structure() can return None for the structure - Various other nullability fixes all over the API, changing functions to accept Option<> or returning Option<>, or only plain types - Functions taking paths/filenames now actually take Paths instead of &strs - Element::remove_pad() is not giving away a new reference to the pad anymore, which caused a memory leak of all pads ever removed - Precision handling in ClockTime's Display impl - Video/AudioInfo are only Send, not Sync ### Added - Various enums now also derive useful traits like Copy, Clone and Hash in addition to PartialEq, Eq and Debug - TagList::merge() and insert() for combining tag lists - EventType gained many useful functions to work with event types and a PartialOrd impl to check expected event order of event types where it matters - MessageRef/EventRef/QueryRef implement ToOwned - Bindings for Registry and PluginFeature - Event::set_running_time_offset() for adjusting the offset while events pass through the pipeline - Event/Message GroupIds and Seqnums now have a newtype wrapper around u32 instead of the plain value, making usage of them slightly more typesafe. Also add an "invalid" value for both, as exists in latest GStreamer now. - FormattedValue, GenericFormattedValue and related types were implemented now, which allows more convenient and type-safe usage of formatted values (time, bytes, etc) - Bindings for force-keyunit and still-frame events were added - MappedBuffer/BufferMap now implement various other useful traits, including AsRef<[u8]>, AsMut, Deref, DerefMut, Debug, PartialEq and Eq - Add VideoMultiviewFramePacking enum, and use it in Player - Bindings for the GStreamer Net library, including PTP/NTP/network client clocks and the GStreamer NetClock provider for network synchronization of pipelines - IteratorError implements std::error:Error - Plugin::add_dependency() and ::add_dependency_simple() was added - Rank and TypeFindProbability implement PartialOrd/Ord now - Bindings for TypeFind, TypeFindFactory and the typefind helpers - StreamCollection::iter() for iterating over all contained streams - ErrorMessage type that can be used e.g. in a Result for passing an error message from somewhere to upper layers to then be posted on an element the same way gst_element_error!() would've done ### Changed - Sample::new(), TagList::add(), Structure::set() and similar functions take the values (ToSendValue impls) by reference instead of value. They were not consumed by the function before. - The Debug impls of various types, including Event/Buffer/Message/Query/Structure were improved to print all the fields, similar to what GST_PTR_FORMAT would do in C - Switched to lazy_static 1.0 - Gap event and Duration tag are using ClockTimes now, as well as various Player signals - Segment is now based on a generic type FormattedSegment that can take any format (time, bytes, etc) or a GenericFormattedValue for more type-safety and convenience. Also functions for "casting" between a generic segment and a segment with a specific format exist on this now - AppSrc and AppSink now have a builder for the callbacks, making it unnecessary to always provide all callbacks even if only one is actually needed - Various functions that returned bool for errors, are now returning a Result - Player configuration is now a custom type with more convenient API - Player VideoInfo uses a Fraction instead of (u32,u32) for the framerate and pixel-aspect-ratio - VideoFrame API has more consistent API between writable and read-only variants - Buffer::copy_into() was added, and ::copy_region() now takes a BufferCopyFlags parameter instead of always using the default flags - ChildProxy::set_child_property() takes a &ToValue now to follow the API of Object::set_property() and improve usability - Proxy/GhostPad default pad functions use the correct specific pad type now instead of a generic Pad - Bus::add_signal_watch_full() takes a Priority for the priority instead of u32 - Clock::(un)adjust_with_calibration() takes no clock parameter anymore ### Removed - FormatValue was removed in favour of GenericFormattedValue and the connected traits and specific format impls ## [0.9.1] - 2017-11-26 ### Fixed - Export `FlowError`/`FlowSuccess`, `ClockError`/`ClockSuccess`, `PadLinkError`/`PadLinkSuccess` too ## [0.9.0] - 2017-11-26 ### Added - Bindings for (outputting to) the GStreamer logging system - Bindings for the GStreamer base library - Bindings for all the `Pad` functions to override pad behaviour, and pad task functions - Bindings for `StaticCaps` and `StaticPadTemplate` - Bindings for `deep-notify` signal on `Object` - Support for directly creating `Error`/`Warning`/`Info` `Messages` and posting them from an element with context information (file, line, module, etc.) similar to the C `GST_ELEMENT_ERROR` macro - Support for setting custom fields in `Messages`/`Events` during construction - Support for creating Buffers out of anything that is `AsRef<[u8]>` or `AsMut<[u8]>` - Support for using the `Read` trait on `Adapter` - Functions for getting all sink/src/all pads of an `Element`, and all children of a `Bin` - Builder for `Caps` and `Structures` in addition to the existing functions - `AppSrc`/`AppSink` implement `BaseSrc`/`BaseSink` and `URIHandler` - Rust ports of the basic tutorials 1 to 8 from https://gstreamer.freedesktop.org/documentation/tutorials/ - "Getting started" and "Installation" sections to the README.md - "dox" feature for generating documentation for all available configurations ### Fixed - `StackTraceFlags` are only available since 1.12 - Worked around macOS requiring a `NSRunLoop` running on the main thread in all examples and tutorials, to be able to show a window or anything else ### Changed - `ClockTime` is now a wrapper around `Option` to handle the `CLOCK_TIME_NONE` case better. This wrapper implements all the arithmetic and other traits as needed and ensures that no accidental calculations with `CLOCK_TIME_NONE` can happen - "Values with format", like in `Duration`/`Position`/`Convert` queries or `Seek` events now return a `FormatValue` type. This contains the actual `Format` together with the value and does any required conversions. This also makes it harder to accidentally mix e.g. values in bytes and time - `PadProbeId` does not implement `Clone`/`Copy` anymore - Property notify watches return a custom type instead of ulong - `Error`/`Warning`/`Info` `Messages` can only be created with specific kinds of `glib::Error` now. Using arbitrary ones does not work - `Iterator` bindings were completely rewritten and provide the item type as a generic type parameter now, greatly simplifying its usage - All `glib::Values` are now `glib::SendValue` instead, e.g. in `Caps` and `Structures`, as their content must be possible to send to different threads safely - `Message::get_src()` can return `None` - Allow `None` as `Caps` in `AppSrc`/`AppSink` - Allow everything implementing `Into>` to be used as a pad name - Moved `copy()` from `GstRc` directly to `MiniObject` - Success/Error enums (like `FlowReturn`, `PadLinkReturn`, `StateChangeReturn`) now implement an `into_result()` function that splits them into a `Result` with the good and bad cases. Also mark them as `#[must_use]` to make it harder to accidentally ignore errors. - Error enums implement the `Error` trait - Many examples use the `failure` crate for error handling now, cleaning up the error handling code quite a bit - Lots of other code cleanup, compiler/clippy warning cleanup, etc. ## [0.8.2] - 2017-11-11 ### Fixed - Implement StaticType of BufferRef instead of Buffer. Buffer aka GstRc already implements StaticType if BufferRef does, and without this it was not possible to use Buffers in GValues. - Free memory of the appsink/appsrc callbacks with the correct type. It was crashing because of using the wrong type before. - Fix documentation URLs in Cargo.toml. ### Added - Installation instructions and links to documentation for getting started to README.md. ## [0.8.1] - 2017-09-15 ### Added - Implement Send+Sync for Query, Message and Event, and their corresponding Ref types. ### Fixed - Constructor for gst_player::Player now works properly with GStreamer 1.12 when passing a video renderer or signal dispatcher. There was a reference counting bug. - Instead of returning &'static references from functions, return references with a generic, unbound lifetime instead. See https://github.com/rust-lang/rust/pull/42417#issue-233404573 - Various "unused external crate" warnings and clippy warnings everywhere. ### Changed - Remove Cargo.lock from GIT, it's not very useful for library crates. - Run everything through latest rustfmt-nightly. - Use while-let (instead of loop and if-let) and CLOCK_TIME_NONE (instead of u64::MAX) in the examples. ## 0.8.0 - 2017-08-31 - Initial release of the autogenerated GStreamer bindings. Older versions (< 0.8.0) of the bindings can be found [here](https://github.com/arturoc/gstreamer1.0-rs). The API of the two is incompatible.
