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. + +[dssim]: https://github.com/pornel/dssim + +### 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. + +- `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 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. + +## 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. + +[timecode-interval]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstvideo.html#gst-video-time-code-interval-new +[buffer-iterate-meta-filtered]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstBuffer.html#gst-buffer-iterate-meta-filtered +[pad-task-get-state]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstPad.html#gst-pad-task-get-state +[uri-get-fragment-table]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstUri.html#gst-uri-get-media-fragment-table +[print]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html#gst-print +[println]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html#gst-println +[printerr]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html#gst-printerr +[printerrln]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html#gst-printerrln +[get-array]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstStructure.html#gst-structure-get-array +[set-array]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstStructure.html#gst-structure-set-array +[get-list]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstStructure.html#gst-structure-get-list +[set-list]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstStructure.html#gst-structure-set-list +[dynamic-type]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstDynamicTypeFactory.html +[proxy-control-binding]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-libs/html/gstreamer-libs-GstProxyControlBinding.html +[calc-lin-regression]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstUtils.html#gst-calculate-linear-regression +[get-stack-trace]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstUtils.html#gst-debug-get-stack-trace + +### GstPlayer + +New API has been added to: + + -

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. + +[snapshot]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-libs/html/gst-plugins-bad-libs-gstplayer.html#gst-player-get-video-snapshot +[renderer-with-vsink]: https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-libs/html/gst-plugins-bad-libs-gstplayer-videooverlayvideorenderer.html#gst-player-video-overlay-video-renderer-new-with-sink + +## 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. + +### 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 + +## 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. + +## 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. + +## 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. + +## 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 + +## 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 + +- Added a way to activate the leaks tracer on our tests and fix leaks + +- Make the http server multithreaded + +- New testsuite for running various test scenarios on the DASH-IF test vectors + +## 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. + +## Platform-specific improvements + +### Android + +- androidmedia: add support for VP9 video decoding/encoding and Opus audio + decoding (where supported) + +### OS/X 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. + +### Windows + +- `dx9screencapsrc` can now optionally also capture the cursor. + +## Contributors + +Aleix Conchillo Flaque, Alejandro G.
