Merge gstreamer-sys into the main repository

Browse source 
More often than not both need to be modified in sync and they share the
gir-files subdirectory anyway. As such it's easier to keep them inside
the same repository.

# How to update the bindings
* Take the updated .gir files (e.g. from your gst-build checkout) and put
them in the gir-files directory
* In the gir-files directory, run ./fix.sh
* In the GstVideo-1.0.gir file, the `GST_VIDEO_BUFFER_FLAG_ONEFIELD` and
`GST_VIDEO_FRAME_FLAG_ONEFIELD` flags are twice. This is a gir bug. Delete
the second one.
* If there is a new GStreamer version: Manually update `gst*/Cargo.toml` and
`gst*/build.rs` files. generator.py will mess these up.
* Run generator.py
* `git checkout gst*/Cargo.toml gst*/build.rs`
* Investigate the diff and fix any mess-ups

[GStreamer](https://gstreamer.freedesktop.org/) FFI bindings for Rust.
These bindings are providing unsafe FFI API that can be used to interface with
GStreamer. Generally they are meant to be used as the building block for
higher-level abstractions like:
* Bindings for GStreamer applications and plugins: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs
* Various GStreamer plugins written in Rust: https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs
The bindings are autogenerated with [gir](https://github.com/gtk-rs/gir/)
based on the [GObject-Introspection](https://wiki.gnome.org/Projects/GObjectIntrospection/)
API metadata provided by the GStreamer project.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html),
specifically the [variant used by Rust](http://doc.crates.io/manifest.html#the-version-field).
## [0.9.1] - 2020-09-08
### 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.
## [0.9.0] - 2020-07-05
### 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.
### Changed
- Minimum supported GStreamer version is 1.8 now.
- The `system-deps` crate is now used for declaring the dependency on the C
libraries instead of directly using `pkg-config`.
### Fixed
- Various missing version markers were added, which should allow compilation
against GStreamer 1.8 on Windows again. On Windows missing symbols are
apparently an error even if they're not used.
- `AUDIO/VIDEO_FORMATS_ALL` are ignored now as they're endian-dependent.
## [0.8.1] - 2019-12-16
### Added
- GStreamer RTP bindings
### Changed
- Update minimum supported Rust version to 1.36
- Update introspection data to GStreamer 1.16.2 release
## [0.8.0] - 2019-06-24
### Added
- GstGLDisplayX11 and GstGLDisplayWayland were added to gstreamer-gl-sys in
addition to GstGLDisplayEGL that existed before
### Changed
- Updated to GStreamer 1.16.0 .gir files, plus backported fixes
- Updated to latest gir
- Run all code through rustfmt after code generation
## [0.7.0] - 2019-02-22
### Added
- GstGL (OpenGL/GLES) bindings
### Changed
- Switch to Rust 1.31 as minimum supported version
- Generate GstVideoOverlayFormatFlags as flags type instead of enum
- Updates GstMpegts with various annotation fixes from GStreamer git master
## [0.6.1] - 2018-11-10
### Added
- GstCheck and GES (gstreamer editing services) bindings
### Changed
- Updated .gir files to 1.14.4 release
- All references were updated from GitHub to freedesktop.org GitLab
- Various functions take \*const instead of \*mut as parameters now
### Fixed
- Various functions and structs having pointer-of-array parameters/fields have
now fixed types. They were previously flat arrays instead of
pointer-of-arrays.
- Set gstreamer-webrtc-sys minimum version to 1.14. It did not exist before
that
## [0.6.0] - 2018-09-08
### Changed
- Updated everything to GStreamer 1.14.2
- Various fixes to how the code generator is used
- Regenerate with latest GIR code generator
### Fixed
- WebRTCICETransport and WebRTCDTLSTransport have the correct parent class
struct
- gstreamer-webrtc-sys correctly depends/links to gstreamer-sys
- Removed unneeded dependencies from the code generator configuration files
## [0.5.0] - 2018-03-20
### Changed
- Updated everything to GStreamer 1.14.0
### Added
- GstSdp, GstRtsp, GstRtspServer and GstWebRTC bindings
### Fixed
- Use external_libraries feature of gir to require less manual editing
- Remove some unused crates from dependencies
- Disale print_system_libs in calls to pkg-config to work better with
non-system installs of GStreamer
## [0.4.1] - 2018-02-18
### Fixed
- Fix native library name of GstNet bindings
## [0.4.0] - 2017-12-23
### Added
- GstNet bindings
- Debug impls for basically every type
- Script to automatically regenerate everything
### Changed
- gst_player_[sg]et_multiview_mode() argument types were changed from
GstMultiviewMode to GstMultiviewFramePacking, which is the correct subset
of the former that is allowed here
- gst_plugin_add_dependency() takes *mut *mut c_char as argument type instead
of *mut *const c_char
## [0.3.0] - 2017-11-26
### Added
- GstMpegTs bindings
### Changed
- GstDebugColorFlags from an enum to a bitfield
- Updated to bitflags 1.0
- Added support for the "dox" feature to generate documentation for all
possible versions
- Depend on glib-sys/gobject-sys 0.5
### Fixes
- GstStackTraceFlags, gst_flow_combiner_ref/unref are only available since
1.12 and 1.12.1 respectively
- All C enums are represented as integers + constants now to prevent undefined
behaviour when out-of-range values are received
## [0.2.1] - 2017-09-10
### Changed
- Add README.md to all crates directly
### Fixed
- Fix various compiler warnings
- Fix versioning/feature mess. Now each library has features for all major
versions and for the correct minor versions that added API.
- Removed Cargo.lock from GIT
## [0.2.0] - 2017-08-28
### Added
- Add GstPlayer bindings
### Changed
- Depend on bitflags 0.9
- Update GIR files to 1.12.1 release
- Fix various errors in the GIR files, backported from GStreamer GIT master
- Depend on gobject-sys/glib-sys 0.4.0 for various improvements
- Regenerated everything with latest GIR
## [0.1.1] - 2017-05-10
### Added
- Add GstTag and GstApp bindings
- Add lots of missing fields to all the structs thanks to GIR improvements
### Changed
- Update GIR files to 1.12.0 release
- Depend on gobject-sys/glib-sys 0.3.4 release for more complete structs
- Regenerated everything with latest GIR
## 0.1.0 - 2017-04-09
- Initial release of the autogenerated GStreamer FFI bindings.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html),
specifically the [variant used by Rust](http://doc.crates.io/manifest.html#the-version-field).
## [0.9.1] - 2020-09-08
### 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.
## [0.9.0] - 2020-07-05
### 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.
### Changed
- Minimum supported GStreamer version is 1.8 now.
- The `system-deps` crate is now used for declaring the dependency on the C
libraries instead of directly using `pkg-config`.
### Fixed
- Various missing version markers were added, which should allow compilation
against GStreamer 1.8 on Windows again. On Windows missing symbols are
apparently an error even if they're not used.
- `AUDIO/VIDEO_FORMATS_ALL` are ignored now as they're endian-dependent.
## [0.8.1] - 2019-12-16
### Added
- GStreamer RTP bindings
### Changed
- Update minimum supported Rust version to 1.36
- Update introspection data to GStreamer 1.16.2 release
## [0.8.0] - 2019-06-24
### Added
- GstGLDisplayX11 and GstGLDisplayWayland were added to gstreamer-gl-sys in
addition to GstGLDisplayEGL that existed before
### Changed
- Updated to GStreamer 1.16.0 .gir files, plus backported fixes
- Updated to latest gir
- Run all code through rustfmt after code generation
## [0.7.0] - 2019-02-22
### Added
- GstGL (OpenGL/GLES) bindings
### Changed
- Switch to Rust 1.31 as minimum supported version
- Generate GstVideoOverlayFormatFlags as flags type instead of enum
- Updates GstMpegts with various annotation fixes from GStreamer git master
## [0.6.1] - 2018-11-10
### Added
- GstCheck and GES (gstreamer editing services) bindings
### Changed
- Updated .gir files to 1.14.4 release
- All references were updated from GitHub to freedesktop.org GitLab
- Various functions take \*const instead of \*mut as parameters now
### Fixed
- Various functions and structs having pointer-of-array parameters/fields have
now fixed types. They were previously flat arrays instead of
pointer-of-arrays.
- Set gstreamer-webrtc-sys minimum version to 1.14. It did not exist before
that
## [0.6.0] - 2018-09-08
### Changed
- Updated everything to GStreamer 1.14.2
- Various fixes to how the code generator is used
- Regenerate with latest GIR code generator
### Fixed
- WebRTCICETransport and WebRTCDTLSTransport have the correct parent class
struct
- gstreamer-webrtc-sys correctly depends/links to gstreamer-sys
- Removed unneeded dependencies from the code generator configuration files
## [0.5.0] - 2018-03-20
### Changed
- Updated everything to GStreamer 1.14.0
### Added
- GstSdp, GstRtsp, GstRtspServer and GstWebRTC bindings
### Fixed
- Use external_libraries feature of gir to require less manual editing
- Remove some unused crates from dependencies
- Disale print_system_libs in calls to pkg-config to work better with
non-system installs of GStreamer
## [0.4.1] - 2018-02-18
### Fixed
- Fix native library name of GstNet bindings
## [0.4.0] - 2017-12-23
### Added
- GstNet bindings
- Debug impls for basically every type
- Script to automatically regenerate everything
### Changed
- gst_player_[sg]et_multiview_mode() argument types were changed from
GstMultiviewMode to GstMultiviewFramePacking, which is the correct subset
of the former that is allowed here
- gst_plugin_add_dependency() takes *mut *mut c_char as argument type instead
of *mut *const c_char
## [0.3.0] - 2017-11-26
### Added
- GstMpegTs bindings
### Changed
- GstDebugColorFlags from an enum to a bitfield
- Updated to bitflags 1.0
- Added support for the "dox" feature to generate documentation for all
possible versions
- Depend on glib-sys/gobject-sys 0.5
### Fixes
- GstStackTraceFlags, gst_flow_combiner_ref/unref are only available since
1.12 and 1.12.1 respectively
- All C enums are represented as integers + constants now to prevent undefined
behaviour when out-of-range values are received
## [0.2.1] - 2017-09-10
### Changed
- Add README.md to all crates directly
### Fixed
- Fix various compiler warnings
- Fix versioning/feature mess. Now each library has features for all major
versions and for the correct minor versions that added API.
- Removed Cargo.lock from GIT
## [0.2.0] - 2017-08-28
### Added
- Add GstPlayer bindings
### Changed
- Depend on bitflags 0.9
- Update GIR files to 1.12.1 release
- Fix various errors in the GIR files, backported from GStreamer GIT master
- Depend on gobject-sys/glib-sys 0.4.0 for various improvements
- Regenerated everything with latest GIR
## [0.1.1] - 2017-05-10
### Added
- Add GstTag and GstApp bindings
- Add lots of missing fields to all the structs thanks to GIR improvements
### Changed
- Update GIR files to 1.12.0 release
- Depend on gobject-sys/glib-sys 0.3.4 release for more complete structs
- Regenerated everything with latest GIR
## 0.1.0 - 2017-04-09
- Initial release of the autogenerated GStreamer FFI bindings.

# NOTE: The canonical repository for gstreamer-sys has moved to [freedesktop.org GitLab](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys)!
# gstreamer-sys [![crates.io](https://img.shields.io/crates/v/gstreamer-audio-sys.svg)](https://crates.io/crates/gstreamer-audio-sys) [![pipeline status](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/badges/master/pipeline.svg)](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/commits/master)
[GStreamer](https://gstreamer.freedesktop.org/) (Audio library) FFI bindings for Rust.
These bindings are providing unsafe FFI API that can be used to interface with
GStreamer. Generally they are meant to be used as the building block for
higher-level abstractions like:
* Bindings for GStreamer applications and plugins: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs
* Various GStreamer plugins written in Rust: https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs
The bindings are autogenerated with [gir](https://github.com/gtk-rs/gir/)
based on the [GObject-Introspection](https://wiki.gnome.org/Projects/GObjectIntrospection/)
API metadata provided by the GStreamer project.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html),
specifically the [variant used by Rust](http://doc.crates.io/manifest.html#the-version-field).
## [0.9.1] - 2020-09-08
### 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.
## [0.9.0] - 2020-07-05
### 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.
### Changed
- Minimum supported GStreamer version is 1.8 now.
- The `system-deps` crate is now used for declaring the dependency on the C
libraries instead of directly using `pkg-config`.
### Fixed
- Various missing version markers were added, which should allow compilation
against GStreamer 1.8 on Windows again. On Windows missing symbols are
apparently an error even if they're not used.
- `AUDIO/VIDEO_FORMATS_ALL` are ignored now as they're endian-dependent.
## [0.8.1] - 2019-12-16
### Added
- GStreamer RTP bindings
### Changed
- Update minimum supported Rust version to 1.36
- Update introspection data to GStreamer 1.16.2 release
## [0.8.0] - 2019-06-24
### Added
- GstGLDisplayX11 and GstGLDisplayWayland were added to gstreamer-gl-sys in
addition to GstGLDisplayEGL that existed before
### Changed
- Updated to GStreamer 1.16.0 .gir files, plus backported fixes
- Updated to latest gir
- Run all code through rustfmt after code generation
## [0.7.0] - 2019-02-22
### Added
- GstGL (OpenGL/GLES) bindings
### Changed
- Switch to Rust 1.31 as minimum supported version
- Generate GstVideoOverlayFormatFlags as flags type instead of enum
- Updates GstMpegts with various annotation fixes from GStreamer git master
## [0.6.1] - 2018-11-10
### Added
- GstCheck and GES (gstreamer editing services) bindings
### Changed
- Updated .gir files to 1.14.4 release
- All references were updated from GitHub to freedesktop.org GitLab
- Various functions take \*const instead of \*mut as parameters now
### Fixed
- Various functions and structs having pointer-of-array parameters/fields have
now fixed types. They were previously flat arrays instead of
pointer-of-arrays.
- Set gstreamer-webrtc-sys minimum version to 1.14. It did not exist before
that
## [0.6.0] - 2018-09-08
### Changed
- Updated everything to GStreamer 1.14.2
- Various fixes to how the code generator is used
- Regenerate with latest GIR code generator
### Fixed
- WebRTCICETransport and WebRTCDTLSTransport have the correct parent class
struct
- gstreamer-webrtc-sys correctly depends/links to gstreamer-sys
- Removed unneeded dependencies from the code generator configuration files
## [0.5.0] - 2018-03-20
### Changed
- Updated everything to GStreamer 1.14.0
### Added
- GstSdp, GstRtsp, GstRtspServer and GstWebRTC bindings
### Fixed
- Use external_libraries feature of gir to require less manual editing
- Remove some unused crates from dependencies
- Disale print_system_libs in calls to pkg-config to work better with
non-system installs of GStreamer
## [0.4.1] - 2018-02-18
### Fixed
- Fix native library name of GstNet bindings
## [0.4.0] - 2017-12-23
### Added
- GstNet bindings
- Debug impls for basically every type
- Script to automatically regenerate everything
### Changed
- gst_player_[sg]et_multiview_mode() argument types were changed from
GstMultiviewMode to GstMultiviewFramePacking, which is the correct subset
of the former that is allowed here
- gst_plugin_add_dependency() takes *mut *mut c_char as argument type instead
of *mut *const c_char
## [0.3.0] - 2017-11-26
### Added
- GstMpegTs bindings
### Changed
- GstDebugColorFlags from an enum to a bitfield
- Updated to bitflags 1.0
- Added support for the "dox" feature to generate documentation for all
possible versions
- Depend on glib-sys/gobject-sys 0.5
### Fixes
- GstStackTraceFlags, gst_flow_combiner_ref/unref are only available since
1.12 and 1.12.1 respectively
- All C enums are represented as integers + constants now to prevent undefined
behaviour when out-of-range values are received
## [0.2.1] - 2017-09-10
### Changed
- Add README.md to all crates directly
### Fixed
- Fix various compiler warnings
- Fix versioning/feature mess. Now each library has features for all major
versions and for the correct minor versions that added API.
- Removed Cargo.lock from GIT

- Regenerated everything with latest GIR
## [0.1.1] - 2017-05-10
### Added
- Add GstTag and GstApp bindings
- Add lots of missing fields to all the structs thanks to GIR improvements
### Changed
- Update GIR files to 1.12.0 release
- Depend on gobject-sys/glib-sys 0.3.4 release for more complete structs
- Regenerated everything with latest GIR
## 0.1.0 - 2017-04-09
- Initial release of the autogenerated GStreamer FFI bindings.

# NOTE: The canonical repository for gstreamer-sys has moved to [freedesktop.org GitLab](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys)!
# gstreamer-sys [![crates.io](https://img.shields.io/crates/v/gstreamer-base-sys.svg)](https://crates.io/crates/gstreamer-base-sys) [![pipeline status](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/badges/master/pipeline.svg)](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/commits/master)
[GStreamer](https://gstreamer.freedesktop.org/) (Base library) FFI bindings for Rust.
These bindings are providing unsafe FFI API that can be used to interface with
GStreamer. Generally they are meant to be used as the building block for
higher-level abstractions like:
* Bindings for GStreamer applications and plugins: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs
* Various GStreamer plugins written in Rust: https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs
The bindings are autogenerated with [gir](https://github.com/gtk-rs/gir/)
based on the [GObject-Introspection](https://wiki.gnome.org/Projects/GObjectIntrospection/)
API metadata provided by the GStreamer project.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html),
specifically the [variant used by Rust](http://doc.crates.io/manifest.html#the-version-field).
## [0.9.1] - 2020-09-08
### 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.
## [0.9.0] - 2020-07-05
### 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.
### Changed
- Minimum supported GStreamer version is 1.8 now.
- The `system-deps` crate is now used for declaring the dependency on the C
libraries instead of directly using `pkg-config`.
### Fixed
- Various missing version markers were added, which should allow compilation
against GStreamer 1.8 on Windows again. On Windows missing symbols are
apparently an error even if they're not used.
- `AUDIO/VIDEO_FORMATS_ALL` are ignored now as they're endian-dependent.
## [0.8.1] - 2019-12-16
### Added
- GStreamer RTP bindings
### Changed
- Update minimum supported Rust version to 1.36
- Update introspection data to GStreamer 1.16.2 release
## [0.8.0] - 2019-06-24
### Added
- GstGLDisplayX11 and GstGLDisplayWayland were added to gstreamer-gl-sys in
addition to GstGLDisplayEGL that existed before
### Changed
- Updated to GStreamer 1.16.0 .gir files, plus backported fixes
- Updated to latest gir
- Run all code through rustfmt after code generation
## [0.7.0] - 2019-02-22
### Added
- GstGL (OpenGL/GLES) bindings
### Changed
- Switch to Rust 1.31 as minimum supported version
- Generate GstVideoOverlayFormatFlags as flags type instead of enum
- Updates GstMpegts with various annotation fixes from GStreamer git master
## [0.6.1] - 2018-11-10
### Added
- GstCheck and GES (gstreamer editing services) bindings
### Changed
- Updated .gir files to 1.14.4 release
- All references were updated from GitHub to freedesktop.org GitLab
- Various functions take \*const instead of \*mut as parameters now
### Fixed
- Various functions and structs having pointer-of-array parameters/fields have
now fixed types. They were previously flat arrays instead of
pointer-of-arrays.
- Set gstreamer-webrtc-sys minimum version to 1.14. It did not exist before
that
## [0.6.0] - 2018-09-08
### Changed
- Updated everything to GStreamer 1.14.2
- Various fixes to how the code generator is used
- Regenerate with latest GIR code generator
### Fixed
- WebRTCICETransport and WebRTCDTLSTransport have the correct parent class
struct
- gstreamer-webrtc-sys correctly depends/links to gstreamer-sys
- Removed unneeded dependencies from the code generator configuration files
## [0.5.0] - 2018-03-20
### Changed
- Updated everything to GStreamer 1.14.0
### Added
- GstSdp, GstRtsp, GstRtspServer and GstWebRTC bindings
### Fixed
- Use external_libraries feature of gir to require less manual editing
- Remove some unused crates from dependencies
- Disale print_system_libs in calls to pkg-config to work better with
non-system installs of GStreamer
## [0.4.1] - 2018-02-18
### Fixed
- Fix native library name of GstNet bindings
## [0.4.0] - 2017-12-23
### Added
- GstNet bindings
- Debug impls for basically every type
- Script to automatically regenerate everything
### Changed
- gst_player_[sg]et_multiview_mode() argument types were changed from
GstMultiviewMode to GstMultiviewFramePacking, which is the correct subset
of the former that is allowed here
- gst_plugin_add_dependency() takes *mut *mut c_char as argument type instead
of *mut *const c_char
## [0.3.0] - 2017-11-26
### Added
- GstMpegTs bindings
### Changed
- GstDebugColorFlags from an enum to a bitfield
- Updated to bitflags 1.0
- Added support for the "dox" feature to generate documentation for all
possible versions
- Depend on glib-sys/gobject-sys 0.5
### Fixes
- GstStackTraceFlags, gst_flow_combiner_ref/unref are only available since
1.12 and 1.12.1 respectively
- All C enums are represented as integers + constants now to prevent undefined
behaviour when out-of-range values are received
## [0.2.1] - 2017-09-10
### Changed
- Add README.md to all crates directly
### Fixed
- Fix various compiler warnings
- Fix versioning/feature mess. Now each library has features for all major
versions and for the correct minor versions that added API.
- Removed Cargo.lock from GIT
## [0.2.0] - 2017-08-28
### Added
- Add GstPlayer bindings
### Changed
- Depend on bitflags 0.9
- Update GIR files to 1.12.1 release
- Fix various errors in the GIR files, backported from GStreamer GIT master
- Depend on gobject-sys/glib-sys 0.4.0 for various improvements
- Regenerated everything with latest GIR
## [0.1.1] - 2017-05-10
### Added
- Add GstTag and GstApp bindings
- Add lots of missing fields to all the structs thanks to GIR improvements
### Changed
- Update GIR files to 1.12.0 release
- Depend on gobject-sys/glib-sys 0.3.4 release for more complete structs
- Regenerated everything with latest GIR
## 0.1.0 - 2017-04-09
- Initial release of the autogenerated GStreamer FFI bindings.

# NOTE: The canonical repository for gstreamer-sys has moved to [freedesktop.org GitLab](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys)!
# gstreamer-check-sys [![crates.io](https://img.shields.io/crates/v/gstreamer-check-sys.svg)](https://crates.io/crates/gstreamer-check-sys) [![pipeline status](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/badges/master/pipeline.svg)](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/commits/master)
[GStreamer](https://gstreamer.freedesktop.org/) (Check library) FFI bindings for Rust.
These bindings are providing unsafe FFI API that can be used to interface with
GStreamer. Generally they are meant to be used as the building block for
higher-level abstractions like:
* Bindings for GStreamer applications and plugins: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs
* Various GStreamer plugins written in Rust: https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs
The bindings are autogenerated with [gir](https://github.com/gtk-rs/gir/)
based on the [GObject-Introspection](https://wiki.gnome.org/Projects/GObjectIntrospection/)
API metadata provided by the GStreamer project.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html),
specifically the [variant used by Rust](http://doc.crates.io/manifest.html#the-version-field).
## [0.9.1] - 2020-09-08
### 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.
## [0.9.0] - 2020-07-05
### 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.
### Changed
- Minimum supported GStreamer version is 1.8 now.
- The `system-deps` crate is now used for declaring the dependency on the C
libraries instead of directly using `pkg-config`.
### Fixed
- Various missing version markers were added, which should allow compilation
against GStreamer 1.8 on Windows again. On Windows missing symbols are
apparently an error even if they're not used.
- `AUDIO/VIDEO_FORMATS_ALL` are ignored now as they're endian-dependent.
## [0.8.1] - 2019-12-16
### Added
- GStreamer RTP bindings
### Changed
- Update minimum supported Rust version to 1.36
- Update introspection data to GStreamer 1.16.2 release
## [0.8.0] - 2019-06-24
### Added
- GstGLDisplayX11 and GstGLDisplayWayland were added to gstreamer-gl-sys in
addition to GstGLDisplayEGL that existed before
### Changed
- Updated to GStreamer 1.16.0 .gir files, plus backported fixes
- Updated to latest gir
- Run all code through rustfmt after code generation
## [0.7.0] - 2019-02-22
### Added
- GstGL (OpenGL/GLES) bindings
### Changed
- Switch to Rust 1.31 as minimum supported version
- Generate GstVideoOverlayFormatFlags as flags type instead of enum
- Updates GstMpegts with various annotation fixes from GStreamer git master
## [0.6.1] - 2018-11-10
### Added
- GstCheck and GES (gstreamer editing services) bindings
### Changed
- Updated .gir files to 1.14.4 release
- All references were updated from GitHub to freedesktop.org GitLab
- Various functions take \*const instead of \*mut as parameters now
### Fixed
- Various functions and structs having pointer-of-array parameters/fields have
now fixed types. They were previously flat arrays instead of
pointer-of-arrays.
- Set gstreamer-webrtc-sys minimum version to 1.14. It did not exist before
that
## [0.6.0] - 2018-09-08
### Changed
- Updated everything to GStreamer 1.14.2
- Various fixes to how the code generator is used
- Regenerate with latest GIR code generator
### Fixed
- WebRTCICETransport and WebRTCDTLSTransport have the correct parent class
struct
- gstreamer-webrtc-sys correctly depends/links to gstreamer-sys
- Removed unneeded dependencies from the code generator configuration files
## [0.5.0] - 2018-03-20
### Changed
- Updated everything to GStreamer 1.14.0
### Added
- GstSdp, GstRtsp, GstRtspServer and GstWebRTC bindings
### Fixed
- Use external_libraries feature of gir to require less manual editing
- Remove some unused crates from dependencies
- Disale print_system_libs in calls to pkg-config to work better with
non-system installs of GStreamer
## [0.4.1] - 2018-02-18
### Fixed
- Fix native library name of GstNet bindings
## [0.4.0] - 2017-12-23
### Added
- GstNet bindings
- Debug impls for basically every type
- Script to automatically regenerate everything
### Changed
- gst_player_[sg]et_multiview_mode() argument types were changed from
GstMultiviewMode to GstMultiviewFramePacking, which is the correct subset
of the former that is allowed here
- gst_plugin_add_dependency() takes *mut *mut c_char as argument type instead
of *mut *const c_char
## [0.3.0] - 2017-11-26
### Added
- GstMpegTs bindings
### Changed
- GstDebugColorFlags from an enum to a bitfield
- Updated to bitflags 1.0
- Added support for the "dox" feature to generate documentation for all
possible versions
- Depend on glib-sys/gobject-sys 0.5
### Fixes
- GstStackTraceFlags, gst_flow_combiner_ref/unref are only available since
1.12 and 1.12.1 respectively
- All C enums are represented as integers + constants now to prevent undefined
behaviour when out-of-range values are received
## [0.2.1] - 2017-09-10
### Changed
- Add README.md to all crates directly
### Fixed
- Fix various compiler warnings
- Fix versioning/feature mess. Now each library has features for all major
versions and for the correct minor versions that added API.
- Removed Cargo.lock from GIT

### Added
- Add GstPlayer bindings
### Changed
- Depend on bitflags 0.9
- Update GIR files to 1.12.1 release
- Fix various errors in the GIR files, backported from GStreamer GIT master
- Depend on gobject-sys/glib-sys 0.4.0 for various improvements
- Regenerated everything with latest GIR
## [0.1.1] - 2017-05-10
### Added
- Add GstTag and GstApp bindings
- Add lots of missing fields to all the structs thanks to GIR improvements
### Changed
- Update GIR files to 1.12.0 release
- Depend on gobject-sys/glib-sys 0.3.4 release for more complete structs
- Regenerated everything with latest GIR
## 0.1.0 - 2017-04-09
- Initial release of the autogenerated GStreamer FFI bindings.

# gstreamer-sys [![crates.io](https://img.shields.io/crates/v/gstreamer-audio-sys.svg)](https://crates.io/crates/gstreamer-audio-sys) [![pipeline status](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/badges/master/pipeline.svg)](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/commits/master)
[GStreamer](https://gstreamer.freedesktop.org/) (Audio library) FFI bindings for Rust.
These bindings are providing unsafe FFI API that can be used to interface with
GStreamer. Generally they are meant to be used as the building block for
higher-level abstractions like:
* Bindings for GStreamer applications and plugins: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs
* Various GStreamer plugins written in Rust: https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs
The bindings are autogenerated with [gir](https://github.com/gtk-rs/gir/)
based on the [GObject-Introspection](https://wiki.gnome.org/Projects/GObjectIntrospection/)
API metadata provided by the GStreamer project.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html),
specifically the [variant used by Rust](http://doc.crates.io/manifest.html#the-version-field).
## [0.9.1] - 2020-09-08
### 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.
## [0.9.0] - 2020-07-05
### 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.
### Changed
- Minimum supported GStreamer version is 1.8 now.
- The `system-deps` crate is now used for declaring the dependency on the C
libraries instead of directly using `pkg-config`.
### Fixed
- Various missing version markers were added, which should allow compilation
against GStreamer 1.8 on Windows again. On Windows missing symbols are
apparently an error even if they're not used.
- `AUDIO/VIDEO_FORMATS_ALL` are ignored now as they're endian-dependent.
## [0.8.1] - 2019-12-16
### Added
- GStreamer RTP bindings
### Changed
- Update minimum supported Rust version to 1.36
- Update introspection data to GStreamer 1.16.2 release
## [0.8.0] - 2019-06-24
### Added
- GstGLDisplayX11 and GstGLDisplayWayland were added to gstreamer-gl-sys in
addition to GstGLDisplayEGL that existed before
### Changed
- Updated to GStreamer 1.16.0 .gir files, plus backported fixes
- Updated to latest gir
- Run all code through rustfmt after code generation
## [0.7.0] - 2019-02-22
### Added
- GstGL (OpenGL/GLES) bindings
### Changed
- Switch to Rust 1.31 as minimum supported version
- Generate GstVideoOverlayFormatFlags as flags type instead of enum
- Updates GstMpegts with various annotation fixes from GStreamer git master
## [0.6.1] - 2018-11-10
### Added
- GstCheck and GES (gstreamer editing services) bindings

[GStreamer](https://gstreamer.freedesktop.org/) (Editing Services) FFI bindings for Rust.
These bindings are providing unsafe FFI API that can be used to interface with
GStreamer. Generally they are meant to be used as the building block for
higher-level abstractions like:
* Bindings for GStreamer applications and plugins: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs
* Various GStreamer plugins written in Rust: https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs
The bindings are autogenerated with [gir](https://github.com/gtk-rs/gir/)
based on the [GObject-Introspection](https://wiki.gnome.org/Projects/GObjectIntrospection/)
API metadata provided by the GStreamer project.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html),
specifically the [variant used by Rust](http://doc.crates.io/manifest.html#the-version-field).
## [0.9.1] - 2020-09-08
### 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.
## [0.9.0] - 2020-07-05
### 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.
### Changed
- Minimum supported GStreamer version is 1.8 now.
- The `system-deps` crate is now used for declaring the dependency on the C
libraries instead of directly using `pkg-config`.
### Fixed
- Various missing version markers were added, which should allow compilation
against GStreamer 1.8 on Windows again. On Windows missing symbols are
apparently an error even if they're not used.
- `AUDIO/VIDEO_FORMATS_ALL` are ignored now as they're endian-dependent.
## [0.8.1] - 2019-12-16
### Added
- GStreamer RTP bindings
### Changed
- Update minimum supported Rust version to 1.36
- Update introspection data to GStreamer 1.16.2 release
## [0.8.0] - 2019-06-24
### Added
- GstGLDisplayX11 and GstGLDisplayWayland were added to gstreamer-gl-sys in
addition to GstGLDisplayEGL that existed before
### Changed
- Updated to GStreamer 1.16.0 .gir files, plus backported fixes
- Updated to latest gir
- Run all code through rustfmt after code generation
## [0.7.0] - 2019-02-22
### Added
- GstGL (OpenGL/GLES) bindings
### Changed
- Switch to Rust 1.31 as minimum supported version
- Generate GstVideoOverlayFormatFlags as flags type instead of enum
- Updates GstMpegts with various annotation fixes from GStreamer git master
## [0.6.1] - 2018-11-10
### Added
- GstCheck and GES (gstreamer editing services) bindings
### Changed
- Updated .gir files to 1.14.4 release
- All references were updated from GitHub to freedesktop.org GitLab
- Various functions take \*const instead of \*mut as parameters now
### Fixed
- Various functions and structs having pointer-of-array parameters/fields have
now fixed types. They were previously flat arrays instead of
pointer-of-arrays.
- Set gstreamer-webrtc-sys minimum version to 1.14. It did not exist before
that
## [0.6.0] - 2018-09-08
### Changed
- Updated everything to GStreamer 1.14.2
- Various fixes to how the code generator is used
- Regenerate with latest GIR code generator
### Fixed
- WebRTCICETransport and WebRTCDTLSTransport have the correct parent class
struct
- gstreamer-webrtc-sys correctly depends/links to gstreamer-sys

non-system installs of GStreamer
## [0.4.1] - 2018-02-18
### Fixed
- Fix native library name of GstNet bindings
## [0.4.0] - 2017-12-23
### Added
- GstNet bindings
- Debug impls for basically every type
- Script to automatically regenerate everything
### Changed
- gst_player_[sg]et_multiview_mode() argument types were changed from
GstMultiviewMode to GstMultiviewFramePacking, which is the correct subset
of the former that is allowed here
- gst_plugin_add_dependency() takes *mut *mut c_char as argument type instead
of *mut *const c_char
## [0.3.0] - 2017-11-26
### Added
- GstMpegTs bindings
### Changed
- GstDebugColorFlags from an enum to a bitfield
- Updated to bitflags 1.0

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html),
specifically the [variant used by Rust](http://doc.crates.io/manifest.html#the-version-field).
## [0.9.1] - 2020-09-08
### 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.
## [0.9.0] - 2020-07-05
### 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.
### Changed
- Minimum supported GStreamer version is 1.8 now.
- The `system-deps` crate is now used for declaring the dependency on the C
libraries instead of directly using `pkg-config`.
### Fixed
- Various missing version markers were added, which should allow compilation
against GStreamer 1.8 on Windows again. On Windows missing symbols are
apparently an error even if they're not used.
- `AUDIO/VIDEO_FORMATS_ALL` are ignored now as they're endian-dependent.
## [0.8.1] - 2019-12-16
### Added
- GStreamer RTP bindings
### Changed
- Update minimum supported Rust version to 1.36
- Update introspection data to GStreamer 1.16.2 release
## [0.8.0] - 2019-06-24
### Added
- GstGLDisplayX11 and GstGLDisplayWayland were added to gstreamer-gl-sys in
addition to GstGLDisplayEGL that existed before
### Changed
- Updated to GStreamer 1.16.0 .gir files, plus backported fixes
- Updated to latest gir
- Run all code through rustfmt after code generation
## [0.7.0] - 2019-02-22
### Added
- GstGL (OpenGL/GLES) bindings
### Changed
- Switch to Rust 1.31 as minimum supported version
- Generate GstVideoOverlayFormatFlags as flags type instead of enum
- Updates GstMpegts with various annotation fixes from GStreamer git master
## [0.6.1] - 2018-11-10
### Added
- GstCheck and GES (gstreamer editing services) bindings
### Changed
- Updated .gir files to 1.14.4 release
- All references were updated from GitHub to freedesktop.org GitLab
- Various functions take \*const instead of \*mut as parameters now
### Fixed
- Various functions and structs having pointer-of-array parameters/fields have
now fixed types. They were previously flat arrays instead of
pointer-of-arrays.
- Set gstreamer-webrtc-sys minimum version to 1.14. It did not exist before
that
## [0.6.0] - 2018-09-08
### Changed
- Updated everything to GStreamer 1.14.2
- Various fixes to how the code generator is used
- Regenerate with latest GIR code generator
### Fixed
- WebRTCICETransport and WebRTCDTLSTransport have the correct parent class
struct
- gstreamer-webrtc-sys correctly depends/links to gstreamer-sys
- Removed unneeded dependencies from the code generator configuration files
## [0.5.0] - 2018-03-20
### Changed
- Updated everything to GStreamer 1.14.0
### Added
- GstSdp, GstRtsp, GstRtspServer and GstWebRTC bindings
### Fixed
- Use external_libraries feature of gir to require less manual editing
- Remove some unused crates from dependencies
- Disale print_system_libs in calls to pkg-config to work better with
non-system installs of GStreamer
## [0.4.1] - 2018-02-18
### Fixed
- Fix native library name of GstNet bindings
## [0.4.0] - 2017-12-23
### Added
- GstNet bindings
- Debug impls for basically every type
- Script to automatically regenerate everything
### Changed
- gst_player_[sg]et_multiview_mode() argument types were changed from
GstMultiviewMode to GstMultiviewFramePacking, which is the correct subset
of the former that is allowed here
- gst_plugin_add_dependency() takes *mut *mut c_char as argument type instead
of *mut *const c_char
## [0.3.0] - 2017-11-26
### Added
- GstMpegTs bindings
### Changed
- GstDebugColorFlags from an enum to a bitfield
- Updated to bitflags 1.0
- Added support for the "dox" feature to generate documentation for all
possible versions
- Depend on glib-sys/gobject-sys 0.5
### Fixes
- GstStackTraceFlags, gst_flow_combiner_ref/unref are only available since
1.12 and 1.12.1 respectively
- All C enums are represented as integers + constants now to prevent undefined
behaviour when out-of-range values are received
## [0.2.1] - 2017-09-10
### Changed
- Add README.md to all crates directly
### Fixed
- Fix various compiler warnings
- Fix versioning/feature mess. Now each library has features for all major
versions and for the correct minor versions that added API.

- Regenerated everything with latest GIR
## [0.1.1] - 2017-05-10
### Added
- Add GstTag and GstApp bindings
- Add lots of missing fields to all the structs thanks to GIR improvements
### Changed
- Update GIR files to 1.12.0 release
- Depend on gobject-sys/glib-sys 0.3.4 release for more complete structs
- Regenerated everything with latest GIR
## 0.1.0 - 2017-04-09
- Initial release of the autogenerated GStreamer FFI bindings.

# NOTE: The canonical repository for gstreamer-sys has moved to [freedesktop.org GitLab](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys)!
# gstreamer-sys [![crates.io](https://img.shields.io/crates/v/gstreamer-mpegts-sys.svg)](https://crates.io/crates/gstreamer-mpegts-sys) [![pipeline status](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/badges/master/pipeline.svg)](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/commits/master)
[GStreamer](https://gstreamer.freedesktop.org/) (MPEGTS library) FFI bindings for Rust.
These bindings are providing unsafe FFI API that can be used to interface with
GStreamer. Generally they are meant to be used as the building block for
higher-level abstractions like:
* Bindings for GStreamer applications and plugins: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs
* Various GStreamer plugins written in Rust: https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs
The bindings are autogenerated with [gir](https://github.com/gtk-rs/gir/)
based on the [GObject-Introspection](https://wiki.gnome.org/Projects/GObjectIntrospection/)
API metadata provided by the GStreamer project.
