+- this section will be completed shortly
## Major new features and changes
### Noteworthy new API
-- The video library gained support for a number of new video formats:
-
- - `GBR_12LE`, `GBR_12BE`, `GBRA_12LE`, `GBRA_12BE` (planar 4:4:4 RGB/RGBA, 12 bits per channel)
- - `GBRA_10LE`, `GBRA_10BE` (planar 4:4:4:4 RGBA, 10 bits per channel)
- - `GBRA` (planar 4:4:4:4 ARGB, 8 bits per channel)
- - `I420_12BE`, `I420_12LE` (planar 4:2:0 YUV, 12 bits per channel)
- - `I422_12BE`,`I422_12LE` (planar 4:2:2 YUV, 12 bits per channel)
- - `Y444_12BE`, `Y444_12LE` (planar 4:4:4 YUV, 12 bits per channel)
- - `VYUY` (another packed 4:2:2 YUV format)
-
-- The high-level `GstPlayer` API was extended with functions for taking video
- snapshots and enabling accurate seeking. It can optionally also use the
- still-experimental `playbin3` element now.
+- this section will be filled in shortly
### New Elements
-- msdk: new plugin for Intel's Media SDK for hardware-accelerated video encoding
- and decoding on Intel graphics hardware on Windows or Linux. This includes
- an H.264 encoder/decoder (`msdkh264dec`, `msdkh264enc`),
- an H.265 encoder/decoder (`msdkh265dec`, `msdkh265enc`),
- an MJPEG encoder/encoder (`msdkmjpegdec`, `msdkmjpegenc`),
- an MPEG-2 video encoder (`msdkmpeg2enc`) and a VP8 encoder (`msdkvp8enc`).
-
-- `iqa` is a new Image Quality Assessment plugin based on [DSSIM][dssim],
- similar to the old (unported) videomeasure element.
-
-- The `faceoverlay` element, which allows you to overlay SVG graphics over
- a detected face in a video stream, has been ported from 0.10.
-
-- our `ffmpeg` wrapper plugin now exposes/maps the ffmpeg Opus audio decoder
- (`avdec_opus`) as well as the GoPro CineForm HD / CFHD decoder (`avdec_cfhd`),
- and also a parser/writer for the IVF format (`avdemux_ivf` and `avmux_ivf`).
-
-- `audiobuffersplit` is a new element that splits raw audio buffers into
- equal-sized buffers
-
-- `audiomixmatrix` is a new element that mixes N:M audio channels according to
- a configured mix matrix.
-
-- The `timecodewait` element got renamed to `avwait` and can operate in
- different modes now.
-
-- The `opencv` video processing plugin has gained a new `dewarp` element that
- dewarps fisheye images.
-
-- `ttml` is a new plugin for parsing and rendering subtitles in Timed Text
- Markup Language (TTML) format. For the time being these elements will not
- be autoplugged during media playback however, unless the `GST_TTML_AUTOPLUG=1`
- environment variable is set. Only the EBU-TT-D profile is supported at this
- point.

+- this section will be filled in shortly
### New element features and additions
-- `x264enc` can now use multiple x264 library versions compiled for different
- bit depths at runtime, to transparently provide support for multiple bit
- depths. A new configure parameter `--with-x264-libraries` has been added to
- specify additional paths to look for additional x264 libraries to load.
- Background is that the libx264 library is always compile for one specific
- bit depth and the `x264enc` element would simply support the depth supported
- by the underlying library. Now we can support multiple depths.
-
-- `x264enc` also picks up the interlacing mode automatically from the input
- caps now and passed interlacing/TFF information correctly to the library.
-
-- `videoscale` and `videoconvert` now support multi-threaded scaling and
- conversion, which is particularly useful with higher resolution video.
- This has to be enabled explicitly via the `"n-threads"` property.
-
-- `videorate`'s new `"rate"` property lets you set a speed factor
- on the output stream
-
-- `splitmuxsink`'s buffer collection and scheduling was rewritten to make
- processing and splitting deterministic; before it was possible for a buffer
- to end up in a different file chunk in different runs. `splitmuxsink` also
- gained a new `"format-location-full"` signal that works just like the existing
- `"format-location"` signal only that it is also passed the primary stream's
- first buffer as argument, so that it is possible to construct the file name
- based on metadata such as the buffer timestamp or any GstMeta attached to
- the buffer. The new `"max-size-timecode"` property allows for timecode-based
- splitting. `splitmuxsink` will now also automatically start a new file if the
- input caps change in an incompatible way.
-
-- `fakesink` has a new `"drop-out-of-segment"` property to not drop
- out-of-segment buffers, which is useful for debugging purposes.
-
-- `identity` gained a `"ts-offset"` property.
-
-- both `fakesink` and `identity` now also print what kind of metas are attached
- to buffers when printing buffer details via the `"last-message"` property
- used by `gst-launch-1.0 -v`.
-
-- multiqueue: made `"min-interleave-time"` a configurable property.
-
-- video nerds will be thrilled to know that `videotestsrc`'s snow is now
- deterministic. `videotestsrc` also gained some new properties to make the
- ball pattern based on system time, and invert colours each second
- (`"animation-mode"`, `"motion"`, and `"flip"` properties).
-
-- `oggdemux` reverse playback should work again now. You're welcome.
-
-- `playbin3` and `urisourcebin` now have buffering enabled by default, and
- buffering message aggregation was fixed.
-
-- `tcpclientsrc` now has a `"timeout"` property
-
-- `appsink` has gained support for buffer lists. For backwards compatibility
- reasons users need to enable this explicitly with `gst_app_sink_set_buffer_list_support()`,
- however. Once activated, a pulled `GstSample` can contain either a buffer
- list or a single buffer.
-
-- `splitmuxsrc` reverse playback was fixed and handling of sparse streams, such
- as subtitle tracks or metadata tracks, was improved.
-
-- `matroskamux` has acquired support for muxing G722 audio; it also marks all
- buffers as keyframes now when streaming only audio, so that `tcpserversink`
- will behave properly with audio-only streams.
-
-- `qtmux` gained support for ProRes 4444 XQ, HEVC/H.265 and CineForm (GoPro) formats,
- and generally writes more video stream-related metadata into the track headers.
- It is also allows configuration of the maximum interleave size in bytes and
- time now. For fragmented mp4 we always write the `tfdt` atom now as required
- by the DASH spec.
-
-- `qtdemux` supports FLAC, xvid, mp2, S16L and CineForm (GoPro) tracks now, and
- generally tries harder to extract more video-related information from track
- headers, such as colorimetry or interlacing details. It also received a
- couple of fixes for the scenario where upstream operates in TIME format and
- feeds chunks to qtdemux (e.g. DASH or MSE).
-
-- `audioecho` has two new properties to apply a delay only to certain channels
- to create a surround effect, rather than an echo on all channels. This is
- useful when upmixing from stereo, for example. The `"surround-delay"` property
- enables this, and the `"surround-mask"` property controls which channels
- are considered surround sound channels in this case.
-
-- `webrtcdsp` gained various new properties for gain control and also exposes
- voice activity detection now, in which case it will post `"voice-activity"`
- messages on the bus whenever the voice detection status changes.
-
-- The `decklink` capture elements for Blackmagic Decklink cards have seen a
- number of improvements:
-
- - `decklinkvideosrc` will post a warning message on "no signal" and an info
- message when the signal lock has been (re)acquired. There is also a new
- read-only `"signal"` property that can be used to query the signal lock
- status. The `GAP` flag will be set on buffers that are captured without
- a signal lock. The new `drop-no-signal-frames` will make `decklinkvideosrc`
- drop all buffers that have been captured without an input signal. The
- `"skip-first-time"` property will make the source drop the first few
- buffers, which is handy since some devices will at first output buffers
- with the wrong resolution before they manage to figure out the right input
- format and decide on the actual output caps.
-
- - `decklinkaudiosrc` supports more than just 2 audio channels now.
-
- - The capture sources no longer use the "hardware" timestamps which turn
- out to be useless and instead just use the pipeline clock directly.
-
-- `srtpdec` now also has a readonly `"stats"` property, just like `srtpenc`.
-
-- `rtpbin` gained RTP bundle support, as used by e.g. WebRTC. The first
- rtpsession will have a `rtpssrcdemux` element inside splitting the streams
- based on their SSRC and potentially dispatch to a different rtpsession.
- Because retransmission SSRCs need to be merged with the corresponding media
- stream the `::on-bundled-ssrc` signal is emitted on `rtpbin` so that the
- application can find out to which session the SSRC belongs.
-
-- `rtprtxqueue` gained two new properties exposing retransmission
- statistics (`"requests"` and `"fulfilled-requests"`)
-
-- `kmssink` will now use the preferred mode for the monitor and render to the
- base plane if nothing else has set a mode yet. This can also be done forcibly
- in any case via the new `"force-modesetting"` property. Furthermore, `kmssink`
- now allows only the supported connector resolutions as input caps in order to
- avoid scaling or positioning of the input stream, as `kmssink` can't know
- whether scaling or positioning would be more appropriate for the use case at
- hand.
-
-- `waylandsink` can now take DMAbuf buffers as input in the presence
- of a compatible Wayland compositor. This enables zero-copy transfer
- from a decoder or source that outputs DMAbuf.
+- this section will be filled in shortly
-- `udpsrc` can be bound to more than one interface when joining a
- multicast group, this is done by giving a comma separate list of
- interfaces such as multicast-iface="eth0,eth1".
-
-### Plugin moves
-
-- `dataurisrc` moved from gst-plugins-bad to core
-
-- The `rawparse` plugin containing the `rawaudioparse` and `rawvideoparse`
- elements moved from gst-plugins-bad to gst-plugins-base. These elements
- supersede the old `videoparse` and `audioparse` elements. They work the
- same, with just some minor API changes. The old legacy elements still
- exist in gst-plugins-bad, but may be removed at some point in the future.
-
-- `timecodestamper` is an element that attaches time codes to video buffers
- in form of `GstVideoTimeCodeMeta`s. It had a `"clock-source"` property
- which has now been removed because it was fairly useless in practice. It
- gained some new properties however: the `"first-timecode"` property can
- be used to set the inital timecode; alternatively `"first-timecode-to-now"`
- can be set, and then the current system time at the time the first buffer
- arrives is used as base time for the time codes.
+### Plugin and library moves
+- this section will be filled in shortly
### Plugin removals
-- The `mad` mp1/mp2/mp3 decoder plugin was removed from gst-plugins-ugly,
- as libmad is GPL licensed, has been unmaintained for a very long time, and
- there are better alternatives available. Use the `mpg123audiodec` element
- from the `mpg123` plugin in gst-plugins-ugly instead, or `avdec_mp3` from
- the `gst-libav` module which wraps the ffmpeg library. We expect that we
- will be able to move mp3 decoding to gst-plugins-good in the next cycle
- seeing that most patents around mp3 have expired recently or are about to
- expire.
-
-- The `mimic` plugin was removed from gst-plugins-bad. It contained a decoder
- and encoder for a video codec used by MSN messenger many many years ago (in
- a galaxy far far away). The underlying library is unmaintained and no one
- really needs to use this codec any more. Recorded videos can still be played
- back with the MIMIC decoder in gst-libav.
+- this section will be filled in shortly

## Miscellaneous API additions
-- Request pad name templates passed to `gst_element_request_pad()` may now
- contain multiple specifiers, such as e.g. `src_%u_%u`.
-
-- [`gst_buffer_iterate_meta_filtered()`][buffer-iterate-meta-filtered] is a
- variant of `gst_buffer_iterate_meta()` that only returns metas of the
- requested type and skips all other metas.
-
-- [`gst_pad_task_get_state()`][pad-task-get-state] gets the current state of
- a task in a thread-safe way.
-
-- [`gst_uri_get_media_fragment_table()`][uri-get-fragment-table] provides the
- media fragments of an URI as a table of key=value pairs.
-
-- [`gst_print()`][print], [`gst_println()`][println], [`gst_printerr()`][printerr],
- and [`gst_printerrln()`][printerrln] can be used to print to stdout or stderr.
- These functions are similar to `g_print()` and `g_printerr()` but they also
- support all the additional format specifiers provided by the GStreamer
- logging system, such as e.g. `GST_PTR_FORMAT`.
-
-- a `GstParamSpecArray` has been added, for elements who want to have array
- type properties, such as the `audiomixmatrix` element for example. There are
- also two new functions to set and get properties of this type from bindings:
- - gst_util_set_object_array()
- - gst_util_get_object_array()
-
-- various helper functions have been added to make it easier to set or get
- GstStructure fields containing caps-style array or list fields from language
- bindings (which usually support GValueArray but don't know about the GStreamer
- specific fundamental types):
- - [`gst_structure_get_array()`][get-array]
- - [`gst_structure_set_array()`][set-array]
- - [`gst_structure_get_list()`][get-list]
- - [`gst_structure_set_list()`][set-list]
-
-- a new ['dynamic type' registry factory type][dynamic-type] was added to
- register dynamically loadable GType types. This is useful for automatically
- loading enum/flags types that are used in caps, such as for example the
- `GstVideoMultiviewFlagsSet` type used in multiview video caps.
-
-- there is a new [`GstProxyControlBinding`][proxy-control-binding] for use
- with GstController. This allows proxying the control interface from one
- property on one GstObject to another property (of the same type) in another
- GstObject. So e.g. in parent-child relationship, one may need to call
- `gst_object_sync_values()` on the child and have a binding (set elsewhere)
- on the parent update the value. This is used in `glvideomixer` and `glsinkbin`
- for example, where `sync_values()` on the child pad or element will call
- `sync_values()` on the exposed bin pad or element.
-
- Note that this doesn't solve GObject property forwarding, that must
- be taken care of by the implementation manually or using GBinding.
-
-- `gst_base_parse_drain()` has been made public for subclasses to use.
-
-- `gst_base_sink_set_drop_out_of_segment()' can be used by subclasses to
- prevent GstBaseSink from dropping buffers that fall outside of the segment.
-
-- [`gst_calculate_linear_regression()`][calc-lin-regression] is a new utility
- function to calculate a linear regression.
-
-- [`gst_debug_get_stack_trace`][get-stack-trace] is an easy way to retrieve a
- stack trace, which can be useful in tracer plugins.
-
-- allocators: the dmabuf allocator is now sub-classable, and there is a new
- `GST_CAPS_FEATURE_MEMORY_DMABUF` define.
-
-- video decoder subclasses can use the newly-added function
- `gst_video_decoder_allocate_output_frame_with_params()` to
- pass a `GstBufferPoolAcquireParams` to the buffer pool for
- each buffer allocation.
-
-- the video time code API has gained a dedicated [`GstVideoTimeCodeInterval`][timecode-interval]
- type plus related API, including functions to add intervals to timecodes.
-
-- There is a new `libgstbadallocators-1.0` library in gst-plugins-bad, which
- may go away again in future releases once the `GstPhysMemoryAllocator`
- interface API has been validated by more users and was moved to
- `libgstallocators-1.0` from gst-plugins-base.

### GstPlayer
-New API has been added to:
-
- - get the number of audio/video/subtitle streams:
- - `gst_player_media_info_get_number_of_streams()`
- - `gst_player_media_info_get_number_of_video_streams()`
- - `gst_player_media_info_get_number_of_audio_streams()`
- - `gst_player_media_info_get_number_of_subtitle_streams()`
-
- - enable accurate seeking: `gst_player_config_set_seek_accurate()`
- and `gst_player_config_get_seek_accurate()`
-
- - get a snapshot image of the video in RGBx, BGRx, JPEG, PNG or
- native format: [`gst_player_get_video_snapshot()`][snapshot]
-
- - selecting use of a specific video sink element
- ([`gst_player_video_overlay_video_renderer_new_with_sink()`][renderer-with-vsink])
-
- - If the environment variable `GST_PLAYER_USE_PLAYBIN3` is set, GstPlayer will
- use the still-experimental `playbin3` element and the `GstStreams` API for
- playback.

+- this section will be filled in shortly
## Miscellaneous changes
-- video caps for interlaced video may contain an optional `"field-order"` field
- now in the case of `interlaced-mode=interleaved` to signal that the field
- order is always the same throughout the stream. This is useful to signal to
- muxers such as mp4mux. The new field is parsed from/to `GstVideoInfo` of course.
-
-- video decoder and video encoder base classes try harder to proxy
- interlacing, colorimetry and chroma-site related fields in caps properly.
-
-- The buffer stored in the `PROTECTION` events is now left unchanged. This is a
- change of behaviour since 1.8, especially for the mssdemux element which used to
- decode the base64 parsed data wrapped in the protection events emitted by the
- demuxer.
-
-- `PROTECTION` events can now be injected into the pipeline from the application;
- source elements deriving from GstBaseSrc will forward those downstream now.
-
-- The DASH demuxer is now correctly parsing the MSPR-2.0 ContentProtection nodes
- and emits Protection events accordingly. Applications relying on those events
- might need to decode the base64 data stored in the event buffer before using it.
-
-- The registry can now also be disabled by setting the environment variable
- `GST_REGISTRY_DISABLE=yes`, with similar effect as the `GST_DISABLE_REGISTRY`
- compile time switch.
-
-- Seeking performance with gstreamer-vaapi based decoders was improved. It would
- recreate the decoder and surfaces on every seek which can be quite slow.
-
-- more robust handling of input caps changes in videoaggregator-based elements
- such as `compositor`.
-
-- Lots of adaptive streaming-related fixes across the board (DASH, MSS, HLS). Also:
-
- - `mssdemux`, the Microsoft Smooth Streaming demuxer, has seen various
- fixes for live streams, duration reporting and seeking.
-
- - The DASH manifest parser now extracts MS PlayReady ContentProtection objects
- from manifests and sends them downstream as `PROTECTION` events. It also
- supports multiple Period elements in external xml now.
-
-- gst-libav was updated to ffmpeg 3.3 but should still work with any 3.x
- version.
-
-- GstEncodingProfile has been generally enhanced so it can, for
- example, be used to get possible profiles for a given file
- extension. It is now possible to define profiles based on element
- factory names or using a path to a `.gep` file containing a
- serialized profile.
-
-- `audioconvert` can now do endianness conversion in-place. All other
- conversions still require a copy, but e.g. sign conversion and a few others
- could also be implemented in-place now.
-
-- The new, experimental `playbin3` and `urisourcebin` elements got many
- bugfixes and improvements and should generally be closer to a full
- replacement of the old elements.
-
-- `interleave` now supports > 64 channels.
+- this section will be filled in shortly
### OpenGL integration
-- As usual the GStreamer OpenGL integration library has seen numerous
- fixes and performance improvements all over the place, and is hopefully
- ready now to become API stable and be moved to gst-plugins-base during the
- 1.14 release cycle.
-
-- The GStreamer OpenGL integration layer has also gained support for the
- Vivante EGL FB windowing system, which improves performance on platforms
- such as Freescale iMX.6 for those who are stuck with the proprietary driver.
- The `qmlglsink` element also supports this now if Qt is used with eglfs or
- wayland backend, and it works in conjunction with [gstreamer-imx][gstreamer-imx]
- of course.
-
-- various `qmlglsrc` improvements
-
-[gstreamer-imx]: https://github.com/Freescale/gstreamer-imx
+- this section will be filled in shortly
## Tracing framework and debugging improvements
-- New tracing hooks have been added to track GstMiniObject and GstObject
- ref/unref operations.
-
-- The memory leaks tracer can optionally use this to retrieve stack traces if
- enabled with e.g. `GST_TRACERS=leaks(filters="GstEvent,GstMessage",stack-traces-flags=full)`
-
-- The `GST_DEBUG_FILE` environment variable, which can be used to write the
- debug log output to a file instead of printing it to stderr, can now contain
- a name pattern, which is useful for automated testing and continuous
- integration systems. The following format specifiers are supported:
-
- - `%p`: will be replaced with the PID
- - `%r`: will be replaced with a random number, which is useful for instance
- when running two processes with the same PID but in different containers.
+- this section will be filled in shortly
## Tools
-- `gst-inspect-1.0` can now list elements by type with the new `--types`
- command-line option, e.g. `gst-inspect-1.0 --types=Audio/Encoder` will
- show a list of audio encoders.
-
-- `gst-launch-1.0` and `gst_parse_launch()` have gained a new operator (`:`)
- that allows linking all pads between two elements. This is useful in cases
- where the exact number of pads or type of pads is not known beforehand, such
- as in the `uridecodebin : encodebin` scenario, for example. In this case,
- multiple links will be created if the encodebin has multiple profiles
- compatible with the output of uridecodebin.
-
-- `gst-device-monitor-1.0` now shows a `gst-launch-1.0` snippet for each
- device that shows how to make use of it in a `gst-launch-1.0` pipeline string.
+- this section will be filled in shortly
## GStreamer RTSP server
-- The RTSP server now also supports Digest authentication in addition to Basic
- authentication.
-
-- The `GstRTSPClient` class has gained a `pre-*-request` signal and virtual
- method for each client request type, emitted in the beginning of each rtsp
- request. These signals or virtual methods let the application validate the
- requests, configure the media/stream in a certain way and also generate error
- status codes in case of an error or a bad request.
+- this section will be filled in shortly
## GStreamer VAAPI
-- GstVaapiDisplay now inherits from GstObject, thus the VA display logging
- messages are better and tracing the context sharing is more readable.
-
-- When uploading raw images into a VA surfaces now VADeriveImages are tried
- fist, improving the upload performance, if it is possible.
-
-- The decoders and the post-processor now can push dmabuf-based buffers to
- downstream under certain conditions. For example:
-
- `GST_GL_PLATFORM=egl gst-play-1.0 video-sample.mkv --videosink=glimagesink`
-
-- Refactored the wrapping of VA surface into gstreamer memory, adding lock
- when mapping and unmapping, and many other fixes.
-
-- Now `vaapidecodebin` loads `vaapipostproc` dynamically. It is possible to
- avoid it usage with the environment variable `GST_VAAPI_DISABLE_VPP=1`.
-
-- Regarding encoders: they have primary rank again, since they can discover,
- in run-time, the color formats they can use for upstream raw buffers and
- caps renegotiation is now possible. Also the encoders push encoding info
- downstream via tags.
-
-- About specific encoders: added constant bit-rate encoding mode for VP8 and
- H265 encoder handles P010_10LE color format.
-
-- Regarding decoders, flush operation has been improved, now the internal VA
- encoder is not recreated at each flush. Also there are several improvements
- in the handling of H264 and H265 streams.
-
-- VAAPI plugins try to create their on GstGL context (when available) if they
- cannot find it in the pipeline, to figure out what type of VA Display they
- should create.
-
-- Regarding `vaapisink` for X11, if the backend reports that it is unable to
- render correctly the current color format, an internal VA post-processor, is
- instantiated (if available) and converts the color format.

## GStreamer Editing Services and NLE
-- Enhanced auto transition behaviour
-
-- Fix some races in `nlecomposition`
-
-- Allow building with msvc
-
-- Added a UNIX manpage for `ges-launch`
-
-- API changes:
- - Added ges_deinit (allowing the leak tracer to work properly)
- - Added ges_layer_get_clips_in_interval
- - Finally hide internal symbols that should never have been exposed
+- this section will be filled in shortly
## GStreamer validate
-- Port `gst-validate-launcher` to python 3
-
-- `gst-validate-launcher` now checks if blacklisted bugs have been fixed on
- bugzilla and errors out if it is the case
-
-- Allow building with msvc
-
-- Add ability for the launcher to run GStreamer unit tests
+- this section will be filled in shortly
-- Added a way to activate the leaks tracer on our tests and fix leaks
+## GStreamer Python Bindings
-- Make the http server multithreaded
-
-- New testsuite for running various test scenarios on the DASH-IF test vectors
+- this section will be filled in shortly
## Build and Dependencies
-- Meson build files are now disted in tarballs, for jhbuild and so distro
- packagers can start using it. Note that the Meson-based build system is not
- 100% feature-equivalent with the autotools-based one yet.
-
-- Some plugin filenames have been changed to match the plugin names: for example
- the file name of the `encoding` plugin in gst-plugins-base containing the
- `encodebin` element was `libgstencodebin.so` and has been changed to
- `libgstencodebin.so`. This affects only a handful of plugins across modules.
-
- **Developers who install GStreamer from source and just do `make install`**
- **after updating the source code, without doing `make uninstall` first, will**
- **have to manually remove the old installed plugin files from the installation**
- **prefix, or they will get 'Cannot register existing type' critical warnings.**
-
-- Most of the docbook-based documentation (FAQ, Application Development Manual,
- Plugin Writer's Guide, design documents) has been converted to markdown and
- moved into a new gst-docs module. The gtk-doc library API references and
- the plugins documentation are still built as part of the source modules though.
-
-- GStreamer core now optionally uses libunwind and libdw to generate backtraces.
- This is useful for tracer plugins used during debugging and development.
-
-- There is a new `libgstbadallocators-1.0` library in gst-plugins-bad (which
- may go away again in future releases once the `GstPhysMemoryAllocator`
- interface API has been validated by more users).
-
-- `gst-omx` and `gstreamer-vaapi` modules can now also be built using the
- Meson build system.
-
-- The `qtkitvideosrc` element for macOS was removed. The API is deprecated
- since 10.9 and it wasn't shipped in the binaries since a few releases.
+- this section will be filled in shortly
## Platform-specific improvements
### Android
-- androidmedia: add support for VP9 video decoding/encoding and Opus audio
- decoding (where supported)
+- this section will be filled in shortly
-### OS/X and iOS
+### macOS and iOS
-- `avfvideosrc`, which represents an iPhone camera or, on a Mac, a screencapture
- session, so far allowed you to select an input device by device index only.
- New API adds the ability to select the position (front or back facing) and
- device-type (wide angle, telephoto, etc.). Furthermore, you can now also
- specify the orientation (portrait, landscape, etc.) of the videostream.
+- this section will be filled in shortly
### Windows
-- `dx9screencapsrc` can now optionally also capture the cursor.
