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 +- 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. - -[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 +- this section will be filled in shortly ### 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. - -[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 +- 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. +- this section will be filled in shortly ## 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. +- this section will be filled in shortly ## Contributors -Aleix Conchillo Flaque, Alejandro G.
