Merge gstreamer-sys into the main repository

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

+
+[GStreamer](https://gstreamer.freedesktop.org/) (App 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

+
+[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
+
+## [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

+
+[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

+  pointer-of-arrays.
+- Set gstreamer-webrtc-sys minimum version to 1.14. It did not exist before
+  that
+

+- 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

+
+### 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

+
+[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

+
+### 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

+
+[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
+
+## [0.2.0] - 2017-08-28
+### Added
+- Add GstPlayer bindings
+
+### Changed
+- Depend on bitflags 0.9

+- 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

+
+[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
+- 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

+
+[GStreamer](https://gstreamer.freedesktop.org/) (OpenGL 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

+
+[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.
