+ While this was already possible through the GLContext machinary, this simply
+ request an alpha channel by default and fallback if this is not possible. This
+ obsolete some RPi Dispmanx hack, since this is near equivalent will allow see
+ through when playgin WebM Alpha or other transparent files.
+ Application are still free to pass their own EGLContext attribute, this is
+ specially for the case the application let GStreamer chose (e.g. gst-launch).

+ gl: add support for A420 conversion
+ A420 is a four planar format similar to I420 but with an extra buffer
+ for alpha values.
+ A common use of the gl stack is for GPU format conversions using
+ shaders, in which case one can use glupload, glcolorconvert and
+ gldownload elements to upload their buffer to the GPU context, perform
+ the conversion on the GPU itself and then retrieve the data to CPU
+ context.
+ A420 was not supported. This patch adds said support mainly by adding
+ the corresponding shader to perform the conversion and updating the
+ supported caps.
+ Both A420->RGBA and RGBA->A420 conversions are supported.

+
+ * ext/gl/gstglcolorbalance.c:
+ glcolorbalance: Error out on unsupported texture target types
+ The issue can be reproduced on a computer with a Radeon graphics card
+ when trying to force GStreamer Editing Services to use GL for video
+ mixing in GESSmartMixer, instead of the GstCompositor that smart mixer
+ would normally use. This change causes the resulting video stream to
+ have "video/x-raw(memory:GLMemory) ... texture-target: 2D" caps (instead
+ of "video/x-raw ..." caps). At the PlaySink stage of the pipeline, a
+ GstGLImageSinkBin is plugged, with a GstGLColorBalance on it. For some
+ reason that is still to be debugged (and out of the scope of this
+ patch), gst_gl_filter_set_caps() is never called on that color balance
+ element, leaving filter->in_texture_target set to its default
+ GST_GL_TEXTURE_TARGET_NONE value. The incomplete _create_shader() logic
+ does the rest and silently generates a shader code that doesn't build.
+ This is the command I use to reproduce the issue (I'm not sure if I
+ would be able to isolate the issue in a simple pipeline, though):

+ Fix this by using gst_video_format_info_component() introduced in 1.18 for

+ should not be used to reference to types outside that.
+ Since C has no notion of member functions it makes little sense to

+ I found a rather reproducible race in a WebKit LayoutTest when a player
+ was intantiated and a VP8/9 video was loaded, then torn down after
+ getting the video dimensions from the caps.
+ The crash occurs during the handling of the first frame by gstvpxdec.
+ The following actions happen sequentially leading to a crash.
+ (MT=Main Thread, ST=Streaming Thread)
+ MT: Sets pipeline state to NULL, which deactivates vpxdec's srcpad,
+ which in turn sets its FLUSHING flag.
+ ST: gst_vpx_dec_handle_frame() -- which is still running -- calls
+ gst_video_decoder_allocate_output_frame(); this in turn calls
+ gst_video_decoder_negotiate_unlocked() which fails because the
+ srcpad is FLUSHING. As a direct consequence of the negotiation
+ failure, a pool is NOT set.
+ gst_video_decoder_negotiate_unlocked() still assumes there is a
+ pool, crashing in a critical in gst_buffer_pool_acquire_buffer()
+ a couple statements later.
+ This patch fixes the bug by returning != GST_FLOW_OK when the
+ negotiation fails. If the srcpad is FLUSHING, GST_FLOW_FLUSHING is
+ returned, otherwise GST_FLOW_ERROR is used.

+ gl/dispmanx: fix deadlock triggered by `set_render_rectangle`
+ When the gstglimagesink is started with the option `glimagesink
+ render-rectangle="<0,0,1920,1080>"`, the pipeline reaches a deadlock.
+ The reason the deadlock occurs is that the
+ `gst_gl_window_set_render_rectangle` takes locks on the window, in
+ addition it calls `window_class->set_render_rectangle(...)` which
+ executes the `_on_resize` function. Since the `_on_resize` function also
+ takes locks on the window the deadlock is achieved.
+ By scheduling the adjustment of the render rectangle through an async
+ message for `gst_gl_window_dispmanx_set_render_rectangle`, the actual
+ resize happens in another context and therefore doesn't suffers from the
+ lock taken in `gst_gl_window_set_render_rectangle`.
+ This solution follows the same approach as gl/wayland. The problem was
+ introduced by b887db1. For the full discussion check #849.

+ tagdemux currently creates a sub-buffer whenever a buffer pulled

+ * gst-libs/gst/video/gstvideoaggregator.c:
+ videoaggregator: Pop out old buffers on timeout
+ This situation happens in the situation where an input stream has a framerate
+ exceeding the timeout latency (Ex: 1fps with a latency of 500ms) and an input
+ stream greater than output framerate (ex: 60fps in, 30 fps out).
+ The problem that would happen is that we would timeout, but then buffers from
+ the fast input stream would only be popped out one by one.... until a buffer
+ reaches the low-framerate input stream at which point they would quickly be
+ popped out/used. The resulting output would be "slow ... fast ... slow ... fast"
+ of that input fast stream.
+ In order to avoid this situation, whenever we detect a late buffer, check if
+ there's a next one and re-check with that one.

+ The second one is about EOS being posted on the bus *before* the

+ * gst-libs/gst/audio/gstaudiobasesrc.c:
+ audiobasesrc: always acquire if not acquired in _setcaps
+ audiobasesrc's setcaps contains an optimization that makes it not re-
+ acquire the ringbuffer if the caps have not changed. However, it doesn't
+ check if it has successfully acquired it or not. It's possible to have
+ the caps set but not having ringbuffer acquired if the previous attempt
+ to acquire fails.
+ This commit replaces the caps existence check with whether the
+ ringbuffer is acquired or not. There's no need to check for caps
+ existence because 1.) it's unlikely to be NULL if the ringbuffer is
+ acquired, and 2.) _setcaps shouldn't be called with a NULL caps.
+ This should also let the element retry on acquiring ringbuffer after an
+ error by re-setting the element's state to READY and back to PLAYING.
+ Whether this behavior is correct is up for debate.

+ video-converter: Skip input lines where possible.
+ There is a case where there are no lines in the temp cache, and
+ it's possible to skip straight to the request line and not generate
+ intermediate ones. This is really only beneficial when doing
+ nearest-neighbour downscaling, as other methods generally require
+ all input lines sequentially to generate the output. In that case,
+ this change has no effect and all lines are generated and cached
+ as before.
+ As a side effect however, this fixes corruption when downscaling
+ using nearest-neighbour, as interactions with the pass_alloc flag
+ and reuse of temporary lines causes the unecessarily-generated
+ cache lines to overwrite the final output.

Major new features and changes
Noteworthy new features and API
-Instant playback rate changes
-
-Changing the playback rate as quickly as possible so far always required
-a flushing seek. This generally works, but has the disadvantage of
-flushing all data from the playback pipeline and requiring the demuxer
-or parser to do a full-blown seek including resetting its internal state
-and resetting the position of the data source. It might also require
-considerable decoding effort to get to the right position to resume
-playback from at the higher rate.
-
-This release adds a new mechanism to achieve quasi-instant rate changes
-in certain playback pipelines without interrupting the flow of data in
-the pipeline. This is activated by sending a seek with the
-GST_SEEK_FLAG_INSTANT_RATE_CHANGE flag and start_type = stop_type =
-GST_SEEK_TYPE_NONE. This flag does not work for all pipelines, in which
-case it is necessary to fall back to sending a full flushing seek to
-change the playback rate. When using this flag, the seek event is only
-allowed to change the current rate and can modify the trickmode flags
-(e.g. keyframe only or not), but it is not possible to change the
-current playback position, playback direction or do a flush.
-
-This is particularly useful for streaming use cases like HLS or DASH
-where the streaming download should not be interrupted when changing
-rate.
-
-Instant rate changing is handled in the pipeline in a specific sequence
-which is detailed in the seeking design docs. Most elements don’t need
-to worry about this, only elements that sync to the clock need some
-special handling which is implemented in the GstBaseSink base class, so
-should be taken care of automatically in most normal playback pipelines
-and sink elements.
-
-See Jan’s GStreamer Conference 2019 talk “Changing Playback Rate
-Instantly” for more information.
-
-You can try this feature by passing the -i command line option to
-gst-play-1.0. It is supported at least by qtdemux, tsdemux, hlsdemux,
-and dashdemux.
-
-Google Transport-Wide Congestion Control
-
-rtpmanager now supports the parsing and generating of RTCP messages for
-the Google Transport-Wide Congestion Control RTP Extension, as described
-in:
-https://tools.ietf.org/html/draft-holmer-rmcat-transport-wide-cc-extensions-01.
-
-This “just” provides the required plumbing/infrastructure, it does not
-actually make effect any actual congestion control on the sender side,
-but rather provides information for applications to use to make such
-decisions.
-
-See Håvard’s “Google Transport-Wide Congestion Control” talk for more
-information about this feature.
-
-GstTranscoder: a new high-level transcoding API for applications
-
-The new GstTranscoder library, along with transcodebin and
-uritranscodebin elements, provides high level API for applications to
-transcode media files from one format to another. Watch Thibault’s talk
-“GstTranscoder: A High Level API to Quickly Implement Transcoding
-Capabilities in your Applications” for more information.
-
-This also comes with a gst-transcoder-1.0 command line utility to
-transcode one URI into another URI based on the specified encoding
-profile.
-
-Active Format Description (AFD) and Bar Data support
-
-The GstVideo Ancillary Data API has gained support for Active Format
-Description (AFD) and Bar data.
-
-This includes various two new buffer metas: GstVideoAFDMeta and
-GstVideoBarMeta.
-
-GStreamer now also parses and extracts AFD/Bar data in the h264/h265
-video parsers, and supports both capturing them and outputting them in
-the decklink elements. See Aaron’s lightning talk at the GStreamer
-Conference for more background.
-
-ONVIF trick modes support in both GStreamer RTSP server and client
-
-- Support for the various trick modes described in section 6 of the
- ONVIF streaming spec has been implemented in both gst-rtsp-server
- and rtspsrc.
-- Various new properties in rtspsrc must be set to take advantage of
- the ONVIF support
-- Examples are available here: test-onvif-server.c and
- test-onvif-client.c
-- Watch Mathieu Duponchelle’s talk “Implementing a Trickmode Player
- with ONVIF, RTSP and GStreamer” for more information and a live
- demo.
-
-GStreamer Codecs library with decoder base classes
-
-This introduces a new library in gst-plugins-bad which contains a set of
-base classes that handle bitstream parsing and state tracking for the
-purpose of decoding different codecs. Currently H264, H265, VP8 and VP9
-are supported. These bases classes are meant primarily for internal use
-in GStreamer and are used in various decoder elements in connection with
-low level decoding APIs like DXVA, NVDEC, VAAPI and V4L2 State Less
-decoders. The new library is named gstreamer-codecs-1.0 /
-libgstcodecs-1.0 and is not yet guaranteed to be API stable across major
-versions.
-
-MPEG-TS muxing improvements
-
-The GStreamer MPEG-TS muxer has seen major improvements on various
-fronts in this cycle:
-
-- It has been ported to the GstAggregator base class which means it
- can work in defined-latency mode with live input sources and
- continue streaming if one of the inputs stops producing data.
-
-- atscmux, a new ATSC-specific tsmux subclass
-
-- Constant Bit Rate (CBR) muxing support via the new bitrate property
- which allows setting the target bitrate in bps. If this is set the
- muxer will insert null packets as padding to achieve the desired
- multiplex-wide constant bitrate.
-
-- compliance fixes for TV broadcasting use cases (esp. ATSC). See
- Jan’s talk “TV Broadcast compliant MPEG-TS” for details.
-
-- Streams can now be added and removed at runtime: Until now, any
- streams in tsmux had to be present when the element started
- outputting its first buffer. Now they can appear at any point during
- the stream, or even disappear and reappear later using the same PID.
-
-- new pcr-interval property allows applications to configure the
- desired interval instead of hardcoding it
-
-- basic SCTE-35 support. This is enabled by setting the scte-35-pid
- property on the muxer. Sending SCTE-35 commands is then done by
- creating the appropriate SCTE-35 GstMpegtsSection and sending them
- on the muxer.
-
-- MPEG-2 AAC handling improvements
+- this section will be filled in in due course
New elements
-- New qmlgloverlay element for rendering a QtQuick scene over the top
- of a video stream. qmlgloverlay requires that Qt support adopting an
- external OpenGL context and is known to work on X11 and Windows.
- Wayland is known not to work due to limitations within Qt. Check out
- the example to see how it works.
-
-- The clocksync element is a generic element that can be placed in a
- pipeline to synchronise passing buffers to the clock at that point.
- This is similar to identity sync=true, but because it isn’t
- GstBaseTransform-based, it can process GstBufferLists without
- breaking them into separate GstBuffers. It is also more discoverable
- than the identity option. Note that you do not need to insert this
- element into your pipeline to make GStreamer sync to the pipeline
- clock, this is usually handled automatically by the elements in the
- pipeline (sources and sinks mostly). This element is useful to feed
- non-live input such as local files into elements that expect live
- input such as webrtcbin.`
-
-- New imagesequencesrc element to easily create a video stream from a
- sequence of JPEG or PNG images (or any other encoding where the type
- can be detected), basically a multifilesrc made specifically for
- image sequences.
-
-- rpicamsrc element for capturing raw or encoded video (H.264, MJPEG)
- from the Raspberry Pi camera. This works much like the popular
- raspivid command line utility but outputs data nicely timestamped
- and formatted in order to integrate nicely with other GStreamer
- elements. Also comes with a device provider so applications can
- discover the camera if available.
-
-- aatv and cacatv video filters that transform video ASCII art style
-
-- avtp: new Audio Video Transport Protocol (AVTP) plugin for Linux.
- See Andre Guedes’ talk “Audio/Video Bridging (AVB) support in
- GStreamer” for more details.
-
-- clockselect: a pipeline element that enables clock selection/forcing
- via gst-launch pipeline syntax.
-
-- dashsink: Add new sink to produce DASH content. See Stéphane’s talk
- or blog post for details.
-
-- dvbsubenc: a DVB subtitle encoder element
-
-- microdns: a libmicrodns-based mdns device provider to discover RTSP
- cameras on the local network
-
-- mlaudiosink: new audio sink element for the Magic Leap platform,
- accompanied by an MLSDK implementation in the amc plugin
-
-- msdkvp9enc: VP9 encoder element for the Intel MediaSDK
-
-- rist: new plugin implementing support for the Video Services Forum’s
- Reliable Internet Stream Transport (RIST) TR-06-1 Simple Profile.
- See Nicolas’ blog post “GStreamer support for the RIST
- Specification” for more details.
-
-- rtmp2: new RTMP client source and sink elements with fully
- asynchronous network operations, better robustness and additional
- features such as handling ping and stats messages, and adobe-style
- authentication. The new rtmp2src and rtmp2sink elements should be
- API-compatible with the old rtmpsrc / rtmpsink elements and should
- work as drop-in replacements.
-
-- new RTP source and sink elements to easily set up RTP streaming via
- rtp:// URIs: The rtpsink and rtpsrc elements add an URI interface so
- that streams can be decoded with decodebin using rtp:// URIs. These
- can be used as follows: ``` gst-launch-1.0 videotestsrc ! x264enc !
- rtph264pay config-interval=3 ! rtpsink uri=rtp://239.1.1.1:1234
-
- gst-launch-1.0 videotestsrc ! x264enc ! rtph264pay config-interval=1
- ! rtpsink uri=rtp://239.1.2.3:5000 gst-launch-1.0 rtpsrc
- uri=rtp://239.1.2.3:5000?encoding-name=H264 ! rtph264depay !
- avdec_h264 ! videoconvert ! xvimagesink
-
- gst-launch-1.0 videotestsrc ! avenc_mpeg4 ! rtpmp4vpay
- config-interval=1 ! rtpsink uri=rtp://239.1.2.3:5000 gst-launch-1.0
- rtpsrc uri=rtp://239.1.2.3:5000?encoding-name=MP4V-ES ! rtpmp4vdepay
- ! avdec_mpeg4 ! videoconvert ! xvimagesink ```
-
-- svthevcenc: new SVT-HEVC-based H.265 video encoder
-
-- switchbin: new helper element which chooses between a set of
- processing chains (paths) based on input caps, and changes the
- active chain if new caps arrive. Paths are child objects, which are
- accessed by the GstChildProxy interface. See the switchbin
- documentation for a usage example.
-
-- vah264dec: new experimental va plugin with an element for H.264
- decoding with VA-API using GStreamer’s new stateless decoder
- infrastructure (see Linux section below).
-
-- v4l2codecs: introduce an V4L2 CODECs Accelerator supporting the new
- CODECs uAPI in the Linux kernel (see Linux section below)
-
-- zxing new plugin to detect QR codes and barcodes, based on libzxing
-
-- also see the Rust plugins section below which contains plenty of new
- exciting plugins written in Rust!
+- this section will be filled in in due course
New element features and additions
-GStreamer core
-
-- filesink: Add a new “full” buffer mode. Previously the default and
- full modes were the same. Now the default mode is like before: it
- accumulates all buffers in a buffer list until the threshold is
- reached and then writes them all out, potentially in multiple
- writes. The new full mode works by always copying memory to a single
- memory area and writing everything out with a single write once the
- threshold is reached.
-
-- multiqueue: Add stats property and
- current-level-{buffers, bytes, time} pad properties to query the
- current levels of the corresponding internal queue.
-
-Plugins Base
-
-- alsa: implement a device provider
-
-- alsasrc: added use-driver-timestamp property to force use of
- pipeline timestamps (and disable driver timestamps) if so desired
-
-- audioconvert: fix changing the mix-matrix property at runtime
-
-- appsrc: added support for segment forwarding or custom GstSegments
- via GstSample, enabled via the handle-segment-change property. This
- only works for segments in TIME format for now.
-
-- compositor: various performance optimisations, checkerboard drawing
- fixes, and support for VUYA format
-
-- encodebin: Fix and refactor smart encoding; ensure that a single
- segment is pushed into encoders; improve force-key-unit event
- handling.
-
-- opusenc: Add low delay option (audio-type=restricted-lowdelay) to
- disable the SILK layer and achieve only 5ms delay.
-
-- opusdec: add stats property to retrieve various decoder statistics.
-
-- uridecodebin3: Let decodebin3 do its stream selection if no one
- answers
-
-- decodebin3: Avoid overriding explicit user selection of streams
-
-- playbin: add flag to force use of software decoders over any
- hardware decoders that might also be available
-
-- playbin3, playbin: propagate sink context
-
-- rawvideoparse: Fix tiling support, allow setting colorimetry
-
-- subparse: output plain utf8 text instead of pango-markup formatted
- text if downstream requires it, useful for interop with elements
- that only accept utf8-formatted subtitles such as muxers or closed
- caption converters.
-
-- tcpserversrc, tcpclientsrc: add stats property with TCP connection
- stats (some are only available on Linux though)
-
-- timeoverlay: add show-times-as-dates, datetime-format and
- datetime-epoch properties to display times with dates
-
-- videorate: Fix changing rate property during playback; reverse
- playback fixes; update QoS events taking into account our rate
-
-- videoscale: pass through and transform size sensitive metas instead
- of just dropping them
-
-Plugins Good
-
-- avidemux can handle H.265 video now. Our advice remains to
- immediately cease all contact and communication with anyone who
- hands you H.265 video in an AVI container, however.
-
-- avimux: Add support for S24LE and S32LE raw audio and v210 raw video
- formats; support more than 2 channels of raw audio.
-
-- souphttpsrc: disable session sharing and cookie jar when the cookies
- property is set; correctly handle seeks past the end of the content
-
-- deinterlace: new YADIF deinterlace method which should provide
- better quality than the existing methods and is LGPL licensed;
- alternate fields are supported as input to the deinterlacer as well
- now, and there were also fixes for switching the deinterlace mode on
- the fly.
-
-- flvmux: in streamable mode allow adding new pads even if the initial
- header has already been written. Old clients will only process the
- initial stream, new clients will get a header with the new streams.
- The skip-backwards-streams property can be used to force flvmux to
- skip and drop a few buffers rather than produce timestamps that go
- backward and confuse librtmp-based clients. There’s also better
- handling for timestamp rollover when streaming for a long time.
-
-- imagefreeze: Add live mode, which can be enabled via the new is-live
- property. In this mode frames will only be output in PLAYING state
- according to the negotiated framerate, skipping frames if the output
- can’t keep up (e.g. because it’s blocked downstream). This makes it
- possible to actually use imagefreeze in live pipelines without
- having to manually ensure somehow that it starts outputting at the
- current running time and without still risking to fall behind
- without recovery.
-
-- matroskademux, qtdemux: Provide audio lead-in for some lossy formats
- when doing accurate seeks, to make sure we can actually decode
- samples at the desired position. This is especially important for
- non-linear audio/video editing use-cases.
-
-- matroskademux, matroskamux: Handle interlaced field order (tff, bff)
-
-- matroskamux:
-
- - new offset-to-zero property to offset all streams to start at
- zero. This takes the timestamp of the earliest stream and
- offsets it so that it starts at 0. Some software (VLC,
- ffmpeg-based) does not properly handle Matroska files that start
- at timestamps much bigger than zero, which could happen with
- live streams.
- - added a creation-time property to explicitly set the creation
- time to write into the file headers. Useful when remuxing, for
- example, but also for live feeds where the DateUTC header can be
- set a UTC timestamp corresponding to the beginning of the file.
- - the muxer now also always waits for caps on sparse streams, and
- warns if caps arrive after the header has already been sent,
- otherwise the subtitle track might be silently absent in the
- final file. This might affect applications that send sparse data
- into matroskamux via an appsrc element, which will usually not
- send out the initial caps before it sends out the first buffer.
-
-- pulseaudio: device provider improvements: fix discovery of
- newly-added devices and hide the alsa device provider if we provide
- alsa devices
-
-- qtdemux: raw audio handling improvements, support for AC4 audio, and
- key-units trickmode interval support
-
-- qtmux:
-
- - was ported to the GstAggregator base class which allows for
- better handling of live inputs, but might entail minor
- behavioural changes for sparse inputs if inputs are not live.
- - has also gained a force-create-timecode-trak property to create
- a timecode trak in non-mov flavors, which may not be supported
- by Apple but is supported by other software such as Final Cut
- Pro X
- - also a force-chunks property to force the creation of chunks
- even in single-stream files, which is required for Apple ProRes
- certification.
- - also supports 8k resolutions in prefill mode with ProRes.
-
-- rtpbin gained a request-jitterbuffer signal which allows
- applications to plug in their own jitterbuffer implementation such
- as the threadsharing jitterbuffer from the Rust plugins, for
- example.
-
-- rtprtxsend: add clock-rate-map property to allow generic RTP input
- caps without a clock-rate whilst still supporting the max-size-time
- property for bundled streams.
-
-- rtpssrcdemux: introduce max-streams property to guard against
- attacks where the sender changes SSRC for every RTP packet.
-
-- rtph264pay, rtph264pay: implement STAP-A and various aggregation
- modes controled by the new aggegrate-mode property: none to not
- aggregate NAL units (as before), zero-latency to aggregate NAL units
- until a VCL or suffix unit is included, or max to aggregate all NAL
- units with the same timestamp (which adds one frame of latency). The
- default has been kept at none for backwards compatibility reasons
- and because various RTP/RTSP implementions don’t handle aggregation
- well. For WebRTC use cases this should be set to zero-latency,
- however.
-
-- rtpmp4vpay: add support for config-interval=-1 to resend headers
- with each IDR keyframe, like other video payloaders.
-
-- rtpvp8depay: Add wait-for-keyframe property for waiting until the
- next keyframe after packet loss. Useful if the video stream was not
- encoded with error resilience enabled, in which case packet loss
- tends to cause very bad artefacts when decoding, and waiting for the
- next keyframe instead improves user experience considerably.
-
-- splitmuxsink and splitmuxsrc can now handle auxiliary video streams
- in addition to the primary video stream. The primary video stream is
- still used to select fragment cut points at keyframe boundaries.
- Auxilliary video streams may be broken up at any packet - so
- fragments may not start with a keyframe for those streams.
-
-- splitmuxsink:
-
- - new muxer-preset and sink-preset properties for setting
- muxer/sink presets
- - a new start-index property to set the initial fragment id
- - and a new muxer-pad-map property which explicitly maps
- splitmuxsink pads to the muxer pads they should connect to,
- overriding the implicit logic that tries to match pads but
- yields arbitrary names.
- - Also includes the actual sink element in the fragment-opened and
- fragment-closed element messages now, which is especially useful
- for sinks without a location property or when finalisation of
- the fragments is done asynchronously.
-
-- videocrop: add support for Y444, Y41B and Y42B pixel formats
-
-- vp8enc, vp9enc: change default value of VP8E_SET_STATIC_THRESHOLD
- from 0 to 1 which matches what Google WebRTC does and results in
- lower CPU usage; also added a new bit-per-pixel property to select a
- better default bitrate
-
-- v4l2: add support for ABGR, xBGR, RGBA, and RGBx formats and for
- handling interlaced video in alternate fields interlace mode (one
- field per buffer instead of one frame per picture with both fields
- interleaved)
-
-- v4l2: Profile and level probing support for H264, H265, MPEG-4,
- MPEG-2, VP8, and VP9 video encoders and decoders
-
-Plugins Ugly
-
-- asfdemux: extract more metadata: disc number and disc count
-
-- x264enc:
-
- - respect YouTube bitrate recommendation when user sets the
- YouTube profile preset
- - separate high-10 video formats from 8-bit formats to improve
- depth negotiation and only advertise suitable input raw formats
- for the desired output depth
- - forward downstream colorimetry and chroma-site restrictions to
- upstream elements
- - support more color primaries/mappings
-
-Plugins Bad
-
-- av1enc: add threads, row-mt and tile-{columns,rows} properties for
- this AOMedia AV1 encoder
-
-- ccconverter: implement support for CDP framerate conversions
-
-- ccextractor: Add remove-caption-meta property to remove caption
- metas from the outgoing video buffers
-
-- decklink: add support for 2K DCI video modes, widescreen NTSC/PAL,
- and for parsing/outputting AFD/Bar data. Also implement a simple
- device provider for Decklink devices.
-
-- dtlsrtpenc: add rtp-sync property which synchronises RTP streams to
- the pipeline clock before passing them to funnel for merging with
- RTCP.
-
-- fdkaac: also decode MPEG-2 AAC; encoder now supports more
- multichannel/surround sound layouts
-
-- hlssink2: add action signals for custom playlist/fragment handling:
- Instead of always going through the file system API we allow the
- application to modify the behaviour. For the playlist itself and
- fragments, the application can provide a GOutputStream. In addition
- the sink notifies the application whenever a fragment can be
- deleted.
-
-- interlace: can now output data in alternate fields mode; added field
- switching mode for 2:2 field pattern
-
-- iqa: Add a mode property to enable strict mode that checks that all
- the input streams have the exact same number of frames; also
- implement the child proxy interface
-
-- mpeg2enc: add disable-encode-retries property for lower CPU usage
-
-- mpeg4videoparse: allow re-sending codec config at IDR via
- config-interval=-1
-
-- mpegtsparse: new alignment property to determine number of TS
- packets per output buffer, useful for feeding an MPEG-TS stream for
- sending via udpsink. This can be used in combination with the
- split-on-rai property that makes sure to start a new output buffer
- for any TS packet with the Random Access Indicator set. Also set
- delta unit buffer flag on non-random-access buffers.
-
-- mpegdemux: add an ignore-scr property to ignore the SCR in
- non-compliant MPEG-PS streams with a broken SCR, which will work as
- long as PTS/DTS in the PES header is consistently increasing.
-
-- tsdemux:
-
- - add an ignore-pcr property to ignore MPEG-TS streams with broken
- PCR streams on which we can’t reliably recover correct
- timestamps.
- - new latency property to allow applications to lower the
- advertised worst-case latency of 700ms if they know their
- streams support this (must have timestamps in higher frequency
- than required by the spec)
- - support for AC4 audio
-
-- msdk - Intel Media SDK plugin for hardware-accelerated video
- decoding and encoding on Windows and Linux:
-
- - mappings for more video formats: Y210, Y410, P012_LE, Y212_LE
- - encoders now support bitrate changes and input format changes in
- playing state
- - msdkh264enc, msdkh265enc: add support for CEA708 closed caption
- insertion
- - msdkh264enc, msdkh265enc: set Region of Interest (ROI) region
- from ROI metas
- - msdkh264enc, msdkh265enc: new tune property to enable low-power

- - msdkh265enc: add support 12-bit 4:2:0 encoding and 8-bit 4:2:2
- encoding and VUYA, Y210, and Y410 as input formats
- - msdkh265enc: add support for screen content coding extension
- - msdkh265dec: add support for main-12/main-12-intra,
- main-422-10/main-422-10-intra 10bit,
- main-422-10/main-422-10-intra 8bit,
- main-422-12/main-422-12-intra, main-444-10/main-444-10-intra,
- main-444-12/main-444-12-intra, and main-444 profiles
- - msdkvp9dec: add support for 12-bit 4:4:4
- - msdkvpp: add support for Y410 and Y210 formats, cropping via
- properties, and a new video-direction property.
-
-- mxf: Add support for CEA-708 CDP from S436 essence tracks. mxfdemux
- can now handle Apple ProRes
-
-- nvdec: add H264 + H265 stateless codec implementation nvh264sldec
- and nvh265sldec with fewer features but improved latency. You can
- set the environment variable GST_USE_NV_STATELESS_CODEC=h264 to use
- the stateless decoder variant as nvh264dec instead of the “normal”
- NVDEC decoder implementation.
-
-- nvdec: add support for 12-bit 4:4:4/4:2:0 and 10-bit 4:2:0 decoding
-
-- nvenc:
-
- - add more rate-control options, support for B-frame encoding (if
- device supports it), an aud property to toggle Access Unit
- Delimiter insertion, and qp-{min,max,const}-{i,p,b} properties.
- - the weighted-pred property enables weighted prediction.
- - support for more input formats, namely 8-bit and 10-bit RGB
- formats (BGRA, RGBA, RGB10A2, BGR10A2) and YV12 and VUYA.
- - on-the-fly resolution changes are now supported as well.
- - in case there are multiple GPUs on the system, there are also
- per-GPU elements registered now, since different devices will
- have different capabilities.
- - nvh265enc can now support 10-bit YUV 4:4:4 encoding and 8-bit
- 4:4:4 / 10-bit 4:2:0 formats up to 8K resolution (with some
- devices). In case of HDR content HDR related SEI nals will be
- inserted automatically.
-
-- openjpeg: enable multi-threaded decoding and add support for
- sub-frame encoding (for lower latency)
-
-- rtponviftimestamp: add opt-out “drop-out-of-segment” property
-
-- spanplc: new stats property
-
-- srt: add support for IPv6 and for using hostnames instead of IP
- addresses; add streamid property, but also allow passing the id via
- the stream URI; add wait-for-connection property to srtsink
-
-- timecodestamper: this element was rewritten with an updated API
- (properties); it has gained many new properties, seeking support and
- support for linear timecode (LTC) from an audio stream.

- camera sources that support this interface (mostly Logitech C920s)
-
-- wpe: Add software rendering support and support for mouse scroll
- events
-
-- x265enc: support more 8/10/12 bits 4:2:0, 4:2:2 and 4:4:4 profiles;
- add support for mastering display info and content light level
- encoding SEIs
-
-gst-libav
-
-- Add mapping for SpeedHQ video codec used by NDI
-
-- Add mapping for aptX and aptX-HD
-
-- avivf_mux: support VP9 and AV1
-
-- avvidenc: shift output buffer timestamps and output segment by 1h
- just like x264enc does, to allow for negative DTS.
-
-- avviddec: Limit default number of decoder threads on systems with
- more than 16 cores, as the number of threads used in avdec has a
- direct impact on the latency of the decoder, which is of as many
- frames as threads, so a large numbers of threads can make for
- latency levels that can be problematic in some applications.
-
-- avviddec: Add thread-type property that allows applications to
- specify the preferred multithreading method (auto, frame, slice).
- Note that thread-type=frame may introduce additional latency
- especially in live pipelines, since it introduces a decoding delay
- of number of thread frames.

Plugin removals
The following elements or plugins have been removed:
-- The yadif video deinterlacing plugin from gst-plugins-bad, which was
- one of the few GPL licensed plugins, has been removed in favour of
- deinterlace method=yadif.
-
-- The avdec_cdgraphics CD Graphics video decoder element from
- gst-libav was never usable in GStreamer and we now have a cdgdec
- element written in Rust in gst-plugins-rs to replace it.
-
-- The VDPAU plugin has been unmaintained and unsupported for a very
- long time and does not have the feature set we expect from
- hardware-accelerated video decoders. It’s been superseded by the
- nvcodec plugin leveraging NVIDIA’s NVDEC API.
+- this section will be filled in in due course
Miscellaneous API additions
-GStreamer core
-
-- gst_task_resume(): This new API allows resuming a task if it was
- paused, while leaving it in stopped state if it was stopped or not
- started yet. This can be useful for callback-based driver workflows,
- where you basically want to pause and resume the task when buffers
- are notified while avoiding the race with a gst_task_stop() coming
- from another thread.
-
-- info: add printf extensions GST_TIMEP_FORMAT and GST_STIMEP_FORMAT
- for printing GstClockTime/GstClockTimeDiff pointers, which is much
- more convenient to use in debug log statements than the usual
- GST_TIME_FORMAT-followed-by-GST_TIME_ARGS dance. Also add an
- explicit GST_STACK_TRACE_SHOW_NONE enum value.
-
-- gst_element_get_current_clock_time() and
- gst_element_get_current_running_time(): new helper functions for
- getting an element clock’s time, and the clock time minus base time,
- respectively. Useful when adding additional input branches to
- elements such as compositor, audiomixer, flvmux, interleave or
- input-selector to determine initial pad offsets and such.
-
-- seeking: Add GST_SEEK_FLAG_TRICKMODE_FORWARD_PREDICTED to just skip
- B-frames during trick mode, showing both keyframes + P-frame, and
- add support for it in h264parse and h265parse.
-
-- elementfactory: add GST_ELEMENT_FACTORY_TYPE_HARDWARE to allow
- elements to advertise that they are hardware-based or interact with
- hardware. This has multiple applications:
-
- - it makes it possible to easily differentiate hardware and
- software based element implementations such as audio or video
- encoders and decoders. This is useful in order to force the use
- of software decoders for specific use cases, or to check if a
- selected decoder is actually hardware-accelerated or not.
- - elements interacting with hardware and their respective drivers
- typically don’t know the actually supported capabilities until
- the element is set into at least READY state and can open a
- device handle and probe the hardware.
-
-- gst_uri_from_string_escaped(): identical to gst_uri_from_string()
- except that the userinfo and fragment components of the URI will not
- be unescaped while parsing. This is needed for correctly parsing
- usernames or passwords with : in them .
-
-- paramspecs: new GstParamSpec flag GST_PARAM_CONDITIONALLY_AVAILABLE
- to indicate that a property might not always exist.
-
-- gst_bin_iterate_all_by_element_factory_name() finds elements in a
- bin by factory name
-
-- pad: gst_pad_get_single_internal_link() is a new convenience
- function to return the single internal link of a pad, which is
- useful e.g. to retrieve the output pad of a new multiqueue request
- pad.
-
-- datetime: Add constructors to create datetimes with timestamps in
- microseconds, gst_date_time_new_from_unix_epoch_local_time_usecs()
- and gst_date_time_new_from_unix_epoch_utc_usecs().
-
-- gst_debug_log_get_lines() gets debug log lines formatted in the same
- way the default log handler would print them
-
-- GstSystemClock: Add GST_CLOCK_TYPE_TAI as GStreamer abstraction for
- CLOCK_TAI, to support transmission offloading features where network
- packets are timestamped with the time they are deemed to be actually
- transmitted. Useful in combination with the new AVTP plugin.
-
-- miscellaneous utility functions: gst_clear_uri(),
- gst_structure_take().
-
-- harness: Added gst_harness_pull_until_eos()
-
-- GstBaseSrc:
-
- - gst_base_src_new_segment() allows subclasses to update the
- segment to be used at runtime from the ::create() function. This
- deprecates gst_base_src_new_seamless_segment()
- - gst_base_src_negotiate() allows subclasses to trigger format
- renegotiation at runtime from inside the ::create() or ::alloc()
- function
-
-- GstBaseSink: new stats property and gst_base_sink_get_stats() method
- to retrieve various statistics such as average frame rate and
- dropped/rendered buffers.
-
-- GstBaseTransform: gst_base_transform_reconfigure() is now public
- API, useful for subclasses that need to completely re-implement the
- ::submit_input_buffer() virtual method
-
-- GstAggregator:
-
- - gst_aggregator_update_segment() allows subclasses to update the
- output segment at runtime. Subclasses should use this function
- rather than push a segment event onto the source pad directly.
- - new sample selection API:
- - subclasses should now call gst_aggregator_selected_samples()
- from their ::aggregate() implementation to signal that they
- have selected the next samples they will aggregate
- - GstAggregator will then emit the samples-selected signal
- where handlers can then look up samples per pad via
- gst_aggregator_peek_next_sample().
- - This is useful for example to atomically update input pad
- properties in mixer subclasses such as compositor.
- Applications can now update properties with precise control
- of when these changes will take effect, and for which input
- buffer(s).
- - gst_aggregator_finish_buffer_list() allows subclasses to push
- out a buffer list, improving efficiency in some cases.
- - a ::negotiate() virtual method was added, for consistency with
- other base classes and to allow subclasses to completely
- override the negotiation behaviour.
- - the new ::sink_event_pre_queue() and ::sink_query_pre_queue()
- virtual methods allow subclasses to intercept or handle
- serialized events and queries before they’re queued up
- internally.
-
-GStreamer Plugins Base Libraries
-
-Audio library
-
-- audioaggregator, audiomixer: new output-buffer-duration-fraction
- property which allows use cases such as keeping the buffers output
- by compositor on one branch and audiomixer on another perfectly
- aligned, by requiring the compositor to output a n/d frame rate, and
- setting output-buffer-duration-fraction to d/n on the audiomixer.
-
-- GstAudioDecoder: new max-errors property so applications can
- configure at what point the decoder should error out, or tell it to
- just keep going
-
-- gst_audio_make_raw_caps() and gst_audio_formats_raw() are
- bindings-friendly versions of the GST_AUDIO_CAPS_MAKE() C macro.
-
-- gst_audio_info_from_caps() now handles encoded audio formats as well
-
-PbUtils library
-
-- GstEncodingProfile:
- - Do not restrict number of similar profiles in a container
- - add GstValue serialization function
-- codec utils now support more H.264/H.265 profiles/levels and have
- improved extension handling
-
-RTP library
-
-- rtpbasepayloader: Add scale-rtptime property for scaling RTP
- timestamp according to the segment rate (equivalent to RTSP speed
- parameter). This is useful for ONVIF trickmodes via RTSP.
-
-- rtpbasepayload: add experimental property for embedding twcc
- sequencenumbers for Transport-Wide Congestion Control (gated behind
- the GST_RTP_ENABLE_EXPERIMENTAL_TWCC_PROPERTY environment
- variable) - more generic API for enabling this is expected to land
- in the next development cycle.
-
-- rtcpbuffer: add RTPFB_TYPE_TWCC for Transport-Wide Congestion
- Control
-
-- rtpbuffer: add
- gst_rtp_buffer_get_extension_onebyte_header_from_bytes()``, so that one can parse theGBytes`
- returned by gst_rtp_buffer_get_extension_bytes()
-
-- rtpbasedepayload: Add max-reorder property to make the
- previously-hardcoded value when to consider a sender to have
- restarted configurable. In some scenarios it’s particularly useful
- to set max-reorder=0 to disable the behaviour that the depayloader
- will drop packets: when max-reorder is set to 0 all
- reordered/duplicate packets are considered coming from a restarted
- sender.
-
-RTSP library
-
-- add gst_rtsp_url_get_request_uri_with_control() to create request
- uri combined with control url
-
-- GstRTSPConnection: add the possibility to limit the Content-Length
- for RTSP messages via
- gst_rtsp_connection_set_content_length_limit(). The same
- functionality is also exposed in gst-rtsp-server.
-
-SDP library
-
-- add support for parsing the extmap attribute from caps and storing
- inside caps The extmap attribute allows mapping RTP extension header
- IDs to well-known RTP extension header specifications. See RFC8285
- for details.
-
-Tags library
-
-- update to latest iso-code and support more languages
-
-- add tags for acoustid id & acoustid fingerprint, plus MusicBrainz ID
- handling fixes
-
-Video library
-
-- High Dynamic Range (HDR) video information representation and
- signalling enhancements:
-
- - New APIs for HDR video information representation and
- signalling:
- - GstVideoMasteringDisplayInfo: display color volume info as
- per SMPTE ST 2086
- - GstVideoContentLightLevel: content light level specified in
- CEA-861.3, Appendix A.
- - plus functions to serialise/deserialise and add them to or
- parse them from caps
- - gst_video_color_{matrix,primaries,transfer}_{to,from}_iso():
- new utilility functions for conversion from/to ISO/IEC
- 23001-8
- - add ARIB STD-B67 transfer chracteristic function
- - add SMPTE ST 2084 support and BT 2100 colorimetry
- - define bt2020-10 transfer characteristics for clarity:
- bt707, bt2020-10, and bt2020-12 transfer characteristics are
- functionally identical but have their own unique values in
- the specification.
- - h264parse, h265parse: Parse mastering display info and content
- light level from SEIs.
- - matroskademux: parse HDR metadata
- - matroskamux: Write MasteringMetadata and Max{CLL,FALL}. Enable
- muxing with HDR meta data if upstream provided it
- - avviddec: Extract HDR information if any and map bt2020-10, PQ
- and HLG transfer functions
-
-- added bt601 transfer function (for completeness)
-
-- support for more pixel formats:
-
- - Y412 (packed 12 bits 4:4:4:4)
- - Y212 (packed 12 bits 4:2:2)
- - P012 (semi-planar 4:2:0)
- - P016_{LE,BE} (semi-planar 16 bits 4:2:0)
- - Y444_16{LE,BE} (planar 16 bits 4:4:4)
- - RGB10A2_LE (packed 10-bit RGB with 2-bit alpha channel)
- - NV12_32L32 (NV12 with 32x32 tiles in linear order)
- - NV12_4L4 (NV12 with 4x4 tiles in linear order)
-
-- GstVideoDecoder:
-
- - new max-errors property so applications can configure at what
- point the decoder should error out, or tell it to just keep
- going
-
- - new qos property to disable dropping frames because of QoS, and
- post QoS messages on the bus when dropping frames. This is
- useful for example in a scenario where the decoded video is
- tee-ed off to go into a live sink that syncs to the clock in one
- branch, and an encoding and save to file pipeline in the other
- branch. In that case one wouldn’t want QoS events from the video
- sink make the decoder drop frames because that would also leave
- gaps in the encoding branch then.
-
-- GstVideoEncoder:
-
- - gst_video_encoder_finish_subframe() is new API to push out
- subframes (e.g. slices), so encoders can split the encoding into
- subframes, which can be useful to reduce the overall end-to-end
- latency as we no longer need to wait for the full frame to be
- encoded to start decoding or sending out the data.
- - new min-force-key-unit-interval property allows configuring the
- minimum interval between force-key-unit requests and prevents a
- big bitrate increase if a lot of key-units are requested in a
- short period of time (as might happen in live streaming RTP
- pipelines when packet loss is detected).
- - various force-key-unit event handling fixes
-
-- GstVideoAggregator, compositor, glvideomixer: expose
- max-last-buffer-repeat property on pads. This can be used to have a
- compositor display either the background or a stream on a lower
- zorder after a live input stream freezes for a certain amount of
- time, for example because of network issues.
-
-- gst_video_format_info_component() is new API to find out which
- components are packed into a given plane, which is useful to prevent
- us from assuming a 1-1 mapping between planes and components.
-
-- gst_video_make_raw_caps() and gst_video_formats_raw() are
- bindings-friendly versions of the GST_VIDEO_CAPS_MAKE() C macro.
-
-- video-blend: Add support for blending on top of 16 bit per component
- formats, which makes sure we can support every currently supported
- raw video format for blending subtitles or logos on top of video.
-
-- GST_VIDEO_BUFFER_IS_TOP_FIELD() and
- GST_VIDEO_BUFFER_IS_BOTTOM_FIELD() convenience macros to check
- whether the video buffer contains only the top field or bottom field
- of an interlaced picture.
-
-- GstVideoMeta now includes an alignment field with the
- GstVideoAlignment so buffer producers can explicitly specify the
- exact geometry of the planes, allowing users to easily know the
- padded size and height of each plane. Default values will be used if
- this is not set.
-
- Use gst_video_meta_set_alignment() to set the alignment and
- gst_video_meta_get_plane_size() or gst_video_meta_get_plane_height()
- to compute the plane sizes or plane heights based on the information
- in the video meta.
-
-- gst_video_info_align_full() works like gst_video_info_align() but
- also retrieves the plane sizes.
-
-MPEG-TS library
-
-- support for SCTE-35 sections
-
-- extend support for ATSC tables:
-
- - System Time Table (STT)
- - Master Guide Table (MGT)
- - Rating Region Table (RRT)
+- this section will be filled in in due course
Miscellaneous performance, latency and memory optimisations
-As always there have been many performance and memory usage improvements
-across all components and modules. Some of them have already been
-mentioned elsewhere so won’t be repeated here.
-
-The following list is only a small snapshot of some of the more
-interesting optimisations that haven’t been mentioned in other contexts
-yet:
-
-- caps negotiation, structure and GValue performance optimizations
-
-- systemclock: clock waiting performance improvements (moved from
- GstPoll to GCond for waiting), especially on Windows.
-
-- rtpsession: add support for buffer lists on the recv path for better
- performance with higher packet rate streams.
-
-- rtpjitterbuffer: internal timer handling has been rewritten for
- better performance, see Nicolas’ talk “Revisiting RTP Jitter Buffer
- Timers” for more details.
-
-- H.264/H.265 parsers and RTP payloaders/depayloaders have been
- optimised for latency to make sure data is processed and pushed out
- as quickly as possible
-
-- video-scaler: correctness and performance improvements, esp. for
- interlaced formats and GBRA
-
-- GstVideoEncoder has gained new API to push out subframes
- (e.g. slices), so encoders can split the encoding into subframes,
- which can be useful to reduce the overall end-to-end latency as we
- no longer need to wait for the full frame to be encoded to start
- decoding or sending out the data.
-
- This is complemented by the new GST_VIDEO_BUFFER_FLAG_MARKER which
- is a video-specific buffer flag to mark the end of a video frame, so
- elements can know that they have received all data for a frame
- without waiting for the beginning of the next frame. This is similar
- to how the RTP marker flag is used in many RTP video mappings.
-
- The video encoder base class now also releases the internal stream
- lock before pushing out data, so as to not block the input side of
- things from processing more data in the meantime.

Miscellaneous other changes and enhancements
-- it is now possible to modify the initial rank of plugin features
- without modifying the source code or writing code to do so
- programmatically via the GST_PLUGIN_FEATURE_RANK environment
- variable. Users can adjust the rank of plugin(s) by passing a
- comma-separated list of feature:rank pairs where rank can be a
- numerical value or one of NONE, MARGINAL, SECONDARY, PRIMARY, and
- MAX. Example: GST_PLUGIN_FEATURE_RANK=myh264dec:MAX,avdec_h264:NONE
- sets the rank of the myh264dec element feature to the maximum and
- that of avdec_h264 to 0 (none), thus ensuring that myh264dec is
- prefered as H264 decoder in an autoplugging context.
-
-- GstDeviceProvider now does a static probe on start as fallback for
- providers that don’t support dynamic probing to make things easier
- for users
-
-WebRTC
-
-- webrtcbin now contains initial support for renegotiation involving
- stream addition and removal. There are a number of caveats to this
- initial renegotiation support and many complex scenarios are known
- to require some work.
-
-- webrtcbin now exposes the internal ICE object for advanced
- configuration options. Using the internal ICE object, it is possible
- to toggle UDP or TCP connection usage as well as provide local
- network addresses.
-
-- Fix a number of call flows within webrtcbin’s GstPromise handling
- where a promise was never replied to. This has been fixed and now a
- promise will always receive a reply.
-
-- webrtcbin now exposes a latency property for configuring the
- internal rtpjitterbuffer latency and buffering when receiving
- streams.
-
-- webrtcbin now only synchronises the RTP part of a stream, allowing
- RTCP messages to skip synchronisation entirely.
-
-- Fixed most of the webrtcbin state properties (connection-state,
- ice-connection-state, signaling-state, but not ice-gathering-state
- as that requires newer API in libnice and will be fixed in the next
- release series) to advance through the state values correctly. Also
- implemented DTLS connection states in the DTLS elements so that
- peer-connection-state is not always new.
-
-- webrtcbin now accounts for the a=ice-lite attribute in a remote SDP
- offer and will configure the internal ICE implementation
- accordingly.
-
-- webrtcbin will now resolve .local candidate addresses using the
- system DNS resolver. .local candidate addresses are now produced by
- web browsers to help protect the privacy of users.
-
-- webrtcbin will now add candidates found in the SDP to the internal
- ICE agent. This was previously unsupported and required using the
- add-ice-candidate signal manually from the application.
-
-- webrtcbin will now correctly parse a TURN URI that contains a
- username or password with a : in it.
-
-- The GStreamer WebRTC library gained a GstWebRTCDataChannel object
- roughly matching the interface exposed by the WebRTC specification
- to allow for easier binding generation and use of data channels.
-
-OpenGL integration
-
-GStreamer OpenGL bindings/build related changes
-
-- The GStreamer OpenGL library (libgstgl) now ships pkg-config files
- for platform-specific API where libgstgl provides a public
- integration interface and a pkg-config file for a dependency on the
- detected OpenGL headers. The new list of pkg-config files in
- addition to the original gstreamer-gl-1.0 are gstreamer-gl-x11-1.0,
- gstreamer-gl-wayland-1.0, gstreamer-gl-egl-1.0, and
- gstreamer-gl-prototypes-1.0 (for OpenGL headers when including
- gst/gl/gstglfuncs.h).
-
-- GStreamer OpenGL now ships some platform-specific introspection data
- for platforms that have a public interface. This should allow for
- easier integration with bindings involving platform specific
- functionality. The new introspection data files are named
- GstGLX11-1.0, GstGLWayland-1.0, and GstGLEGL-1.0.
-
-GStreamer OpenGL Features
-
-- The iOS implementation no longer accesses UIKit objects off the main
- thread fixing a loud warning message when used in iOS applications.
-
-- Support for mouse and keyboard handling using the GstNavigation
- interface was added for the wayland implementation complementing the
- already existing support for the X11 and Windows implementations.
-
-- A new helper base class for source elements, GstGLBaseSrc is
- provided to ease writing source elements producing OpenGL video
- frames.
-
-- Support for some more 12-bit and 16-bit video formats (Y412_LE,
- Y412_BE, Y212_LE, Y212_BE, P012_LE, P012_BE, P016, NV16, NV61) was
- added to glcolorconvert.
-
-- glupload can now import dma-buf’s into external-oes textures.
-
-- A new display type for EGLDevice-based systems was added. It is
- currently opt-in by using either the GST_GL_PLATFORM=egl-device
- environment variable or manual construction
- (gst_gl_display_egl_device_new*()) due to compatibility issues with
- some platforms.
-
-- Support was added for WinRT/UWP using the ANGLE project for running
- OpenGL-based pipelines within a UWP application.
-
-- Various elements now support changing the GstGLDisplay to be used at
- runtime in simple cases. This is primarily helpful for changing or
- adding an OpenGL-based video sink that must share an OpenGL context
- with an external source to an already running pipeline.
-
-GStreamer Vulkan integration
-
-- There is now a GStreamer Vulkan library to provide integration
- points and helpers with applications and external GStreamer Vulkan
- based elements. The structure of the library is modelled similarly
- to the already existing GStreamer OpenGL library. Please note that
- the API is still unstable and may change in future releases,
- particularly around memory handling. The GStreamer Vulkan library
- contains objects for sharing the vkInstance, vkDevice, vkQueue,
- vkImage, VkMemory, etc with other elements and/or the application as
- well as some helper objects for using Vulkan in an application or
- element.
-
-- Added support for building and running on/for the Android and
- Windows systems to complement the existing XCB, Wayland, MacOS, and
- iOS implementations.
-
-- XCB gained support for mouse/keyboard events using the GstNavigation
- API.
-
-- New vulkancolorconvert element for converting between color formats.
- vulkancolorconvert can currently convert to/from all 8-bit RGBA
- formats as well as 8-bit RGBA formats to/from the YUV formats AYUV,
- NV12, and YUY2.
-
-- New vulkanviewconvert element for converting between stereo view
- layouts. vulkanviewconvert can currently convert between all of the
- single memory formats (side-by-side, top-bottom, column-interleaved,
- row-interleaved, checkerboard, left, right, mono).
-
-- New vulkanimageidentity element for a blit from the input vulkan
- image/s to a new vulkan image/s.
-
-- The vulkansink element can now scale the input image to the output
- window/surface size where that information is available.
-
-- The vulkanupload element can now configure a transfer from system
- memory to VulkanImage-based memory. Previously, this required two
- vulkanupload elements.
+- this section will be filled in in due course
Tracing framework and debugging improvements
-- gst_tracing_get_active_tracers() returns a list of active tracer
- objects. This can be used to interact with tracers at runtime using
- GObject API such as action signals. This has been implemented in the
- leaks tracer for snapshotting and retrieving leaked/active objects
- at runtime.
-
-- The leaks tracer can now be interacted with programmatically at
- runtime via GObject action signals:
-
- - get-live-object returns a list of live (allocated) traced
- objects
- - log-live-objects logs a list of live objects into the debug log.
- This is the same as sending the SIGUSR1 signal on unix systems,
- but works on all operating systems including Windows.
- - activity-start-tracking, activity-get-checkpoint,
- activity-log-checkpoint, activity-stop-tracking: add support for
- tracking and checkpointing objects, similar to what was
- previously available via SIGUSR2 on unix systems, but works on
- all operating systems including Windows.
-
-- various GStreamer gdb debug helper improvements:
-
- - new ‘gst-pipeline-tree’ command
- - more gdb helper functions: gst_element_pad(), gst_pipeline() and
- gst_bin_get()
- - support for queries and buffers
- - print more info for segment events, print event seqnums, object
- pointers and structures
- - improve gst-print command to show more pad and element
- information
+- this section will be filled in in due course
Tools
-gst-launch-1.0
-
-- now prints the pipeline position and duration if available when the
- pipeline is advancing. This is hopefully more user-friendly and
- gives visual feedback on the terminal that the pipeline is actually
- up and running. This can be disabled with the --no-position command
- line option.
-
-- the parse-launch pipeline syntax now has support for presets:
- use@preset=<preset-name>" after an element to load a preset.
-
-gst-inspect-1.0
-
-- new --color command line option to force coloured output even if not
- connected to a tty
-
-gst-tester-1.0 (new)
-
-- gst-tester-1.0 is a new tool for plugin developers to launch
- .validatetest files with TAP compatible output, meaning it can
- easily and cleanly be integrated with the meson test harness. It
- allows you to use gst-validate (from the gst-devtools module) to
- write integration tests in any GStreamer repository whilst keeping
- the tests as close as possible to the code. The tool transparently
- handles gst-validate being installed or not: if it is not installed
- those integration tests will simply be skipped.
-
-gst-play-1.0
-
-- interactive keyboard controls now also work on Windows
-
-gst-transcoder-1.0 (new)
-
-- gst-transcoder-1.0 is a new command line tool to transcode one URI
- into another URI based on the specified encoding profile using the
- new GstTranscoder API (see above).
+- this section will be filled in in due course
GStreamer RTSP server
-- Fix issue where the first few packets (i.e. keyframes) could
- sometimes be dropped if the rtsp media pipeline had a live input.
- This was a regression from GStreamer 1.14. There are more fixes
- pending for that which will hopefully land in 1.18.1.
-
-- Fix backpressure handling when sending data in TCP interleave mode
- where RTSP requests and responses and RTP/RTCP packets flow over the
- same RTSP TCP connection: The previous implementation would at some
- point stop sending data to other clients when a single client
- stopped consuming data or did not consume data fast enough. This
- obviously created problems for shared media, where the same stream
- from a single producer pipeline is sent to multiple clients. Instead
- we now manage a backlog in the server’s stream-transport component
- and remove slow clients once this backlog exceeds a maximum duration
- (which is currently hardcoded).
-
-- Onvif Streaming Specification trick modes support (see section at
- the beginning)
-
-- Scale/Speed header support: Speed will deliver the data at the
- requested speed, which means increasing the data bandwidth for
- speeds > 1.0. Scale will attempt to do the same without affecting
- the overall bandwidth requirement vis-a-vis normal playback speed
- (e.g. it might drop data for fast-forward playback).
-
-- rtspclientsink: send buffer lists in one go for better performance
+- this section will be filled in in due course
GStreamer VAAPI
-- A lot of work was done adding support for media-driver (iHD), the
- new VAAPI driver for Intel, mostly for Gen9 onwards.
-
-- Available color formats and frame sizes are now detected at run-time
- according to the context configuration.
-
-- Gallium drivers have been re-enabled in the allowed drivers list
-
-- Improved the mapping between VA formats and GStreamer formats by
- generating a mapping table at run-time since even among different
- drivers the mapping might be different, particularly for RGB with
- little endianness.
-
-- The experimental Flexible Encoding Infrastructure (FEI) elements
- have been removed since they were not really actively maintained or
- tested.
-
-- Enhanced the juggling of DMABuf buffers and VASurface metas
-
-- New vaapioverlay element: a compositor element using VA VPP blend
- capabilities to accelerate overlaying and compositing. Example
- pipeline:
-
- gst-launch-1.0 -vf videotestsrc ! vaapipostproc ! tee name=testsrc ! queue \
- ! vaapioverlay sink_1::xpos=300 sink_1::alpha=0.75 name=overlay ! vaapisink \
- testsrc. ! queue ! overlay.
-
-vaapipostproc
-
-- added video-orientation support, supporting frame mirroring and
- rotation
-
-- added cropping support, either via properties (crop-left,
- crop-right, crop-bottom and crop-top) or buffer meta.
-
-- new skin-tone-enhancenment-level property which is the iHD
- replacement of the i965 driver’s sink-tone-level. Both are
- incompatible with each other, so both were kept.
-
-- handle video colorimetry
-
-- support HDR10 tone mapping
-
-vaapisink
-
-- resurrected wayland backend for non-weston compositors by extracting
- the DMABuf from the VASurface and rendering it.
-
-- merged the video overlay API for wayland. Now applications can
- define the “window” to render on.
-
-- demoted the vaapisink element to secondary rank since libva
- considers rendering as a second-class feature.
-
-VAAPI Encoders
-
-- new common target-percentage property which is the desired target
- percentage of bitrate for variable rate control.
-
-- encoders now extract their caps from the driver at registration
- time.
-
-- vaapivp9enc: added support for low power mode and support for
- profile 2 (profile 0 by default)
-
-- vaapih264enc: new max-qp property that sets the maximum quantization
- value. Support for ICQ and QBVR bitrate control mode, adding a

GStreamer Editing Services and NLE
-- Added nested timelines and subproject support so that GES projects
- can be used as clips, potentially serializing nested projects in the
- main file or referencing external project files.
-
-- Implemented an OpenTimelineIO GES formatter. This means GES and
- GStreamer can now load and save projects in all the formats
- supported by otio.
-
-- Implemented a GESMarkerList object which allow setting timed
- metadata on any GES object.
-
-- Fixed audio rendering issues during clip transition by ensuring that
- a single segment is pushed into encoders.
-
-- The GESUriClipAsset API is now MT safe.
-
-- Added ges_meta_container_register_static_meta() to allow fixing a
- type for a specific metadata without actually setting a value.
-
-- The framepositioner element now handles resizing the project and
- keeps the same positioning when the aspect ratio is not changed .
-
-- Reworked the documentation, making it more comprehensive and much
- more detailed.
-
-- Added APIs to retrieve natural size and framerate of a clip (for
- example in the case of URIClip it is the framerate/size of the
- underlying file).
-
-- ges_container_edit() is now deprecated and GESTimelineElement gained
- the ges_timeline_element_edit() method so the editing API is now
- usable from any element in the timeline.
-
-- GESProject::loading was added so applications can be notified about
- when a new timeline starts loading.
-
-- Implemented the GstStream API in GESTimeline.
-
-- Added a way to add a timeoverlay inside the test source (potentially
- with timecodes).
-
-- Added APIs to convert times to frame numbers and vice versa:
-
- - ges_timeline_get_frame_time()
-
- - ges_timeline_get_frame_at()
-
- - ges_clip_asset_get_frame_time()
-
- - ges_clip_get_timeline_time_from_source_frame()

-- Added ges_layer_set_active_for_tracks() which allows muting layers
- for the specified tracks
-
-- Deprecated GESImageSource and GESMultiFileSource now that we have
- imagesequencesrc which handles the imagesequence “protocol”
-
-- Stopped exposing ‘deinterlacing’ children properties for clip types
- where they do not make sense.

GStreamer validate
-- Introduced the concept of “Test files” allowing to implement “all
- included” test cases, meaning that inside the file the following can
- be defined:
-
- - The application arguments
- - The validate configurations
- - The validate scenario
-
- This replaces the previous big dictionary file in
- gst-validate-launcher to implement specific test cases.
-
- We set several variables inside the files (as well as inside
- scenarios and config files) to make them relocatable.
-
- The file format has been enhanced so it is easier to read and write,
- for example line ending with a coma or (curly) brackets can now be
- used as continuation marker so you do not need to add \ at the end
- of lines to write a structure on several lines.
-
-- Support the imagesequence “protocol” and added integration tests for
- it.
-
-- Added action types to allow the scenario to run the Test Clock for
- better reproducibility of tests.
-
-- Support generating tests to check that seeking is frame accurate
- (base on ssim).
-
-- Added ways to record buffers checksum (in different ways) in the
- validateflow module.
-
-- Added vp9 encoding tests.
-
-- Enhanced seeking action types implementation to allow support for
- segment seeks.
-
-- Output improvements:
-
- - Logs are now in markdown formats (and bat is used to dump them
- if available).
- - File format issues in scenarios/configs/tests files are nicely
- reported with the line numbers now.

GStreamer C# Bindings
-- Bind gst_buffer_new_wrapped() manually to fix memory handling.
-
-- Fix gst_promise_new_with_change_func() where bindgen didn’t properly
- detect the func as a closure.
-
-- Declare GstVideoOverlayComposition and GstVideoOverlayRectangle as
- opaque type and subclasses of Gst.MiniObject. This changes the API
- but without this all usage will cause memory corruption or simply
- not work.
-
-- on Windows, look for gstreamer, glib and gobject DLLs using the MSVC
- naming convention (i.e. gstvideo-1.0-0.dll instead of
- libgstvideo-1.0-0.dll).
-
- The names of these DLLs have to be hardcoded in the bindings, and
- most C# users will probably be using the Microsoft toolchain anyway.
-
- This means that the MSVC compiler is now required to build the
- bindings, MingW will no longer work out of the box.

-
-gst-build is based on Meson and replaces the old autotools
-gst-uninstalled script.
-
-- The ‘uninstalled’ target has been renamed to ‘devenv’
-
-- Experimental gstreamer-full library containing all built plugins and
- their deps when building with -Ddefault_library=static. A monolithic
- library is easier to distribute, and may be required in some
- environments. GStreamer core, GLib and GObject are always included,
- but external dependencies are still dynamically linked. The
- gst-full-libraries meson option allows adding other GStreamer
- libraries to the gstreamer-full build. This is an experiment for now
- and its behaviour or API may still change in future releases.

-- Several recipes can now be buit with Visual Studio instead of MinGW.
- Ported to meson: opus, libsrtp, harfbuzz, cairo, openh264, libsoup,
- libusrsctp. Existing build system: libvpx, openssl.
-- Support building using Visual Studio for 32-bit x86. Previously we

-- Fixed annoying msgmerge popups in the middle of cerbero builds
-- Added configuration options vs_install_path and vs_install_version
- for specifying custom search locations for older Visual Studio
- versions that do not support vswhere. You can set these in

- decoding are H.264, H.265, VP8, and VP9, and zero-copy operation
- should be supported in combination with the new d3d11videosink. See
- Seungha’s blog post “Windows DXVA2 (via Direct3D 11) Support in
- GStreamer 1.17” for more details.

-- Microsoft Media Foundation plugin for hardware-accelerated video
- encoding on Windows using native Windows APIs rather than per-vendor
- SDKs. Formats supported for encoding are H.264, H.265 and VP9. Also
- includes audio encoders for AAC and MP3. See Seungha’s blog post
- “Bringing Microsoft Media Foundation to GStreamer” for some more
- details about this.
-
-- new mfvideosrc video capture source element using the latest Windows
- APIs rather than ancient APIs used by ksvideosrc/winks. ksvideosrc
- should be considered deprecated going forward.

- be meaningless in themselves, only the rate of increase matters).
-
-- toolchain specific plugin registry: the registry cache is now named
- differently for MSVC and MinGW toolchains/packages, which should
- avoid problems when switching between binaries built with a
- different toolchain.
-
-- new wasapi2 plugin mainly to support UWP applications. The core
- logic of this plugin is almost identical to existing wasapi plugin,
- but the main target is Windows 10 and UWP. This plugin uses WinRT
- APIs, so will likely not work on Windows 8 or older. Unlike the
- existing wasapi plugin, this plugin supports automatic stream
- routing (auto fallback when device was removed) and device level
- mute/volume control. Exclusive streaming mode is not supported,
- however, and loopback features are not implemented yet. It is also
- only possible to build this plugin with MSVC and the Windows 10 SDK,
- it can’t be cross-compiled with the MingW toolchain.

- frei0r, as well as tracer plugins.
-
-- for more info, check out Thibault’s “GStreamer Documentation”
- lightning talk from the 2019 GStreamer Conference.
-
-- new API for plugins to support the documentation system:
-
- - new GParamSpecFlag GST_PARAM_DOC_SHOW_DEFAULT to make
- gst-inspect-1.0 (and the documentation) show the paramspec’s
- default value rather than the actually set value as default
- - GstPadTemplate getter and setter for “documentation caps”,
- gst_pad_template_set_documentation_caps() and
- gst_pad_template_get_documentation_caps(): This can be used in
- elements where the caps of pad templates are dynamically
- generated and/or dependent on the environment, to override the
- caps shown in the documentation (usually to advertise the full
- set of possible caps).
- - gst_type_mark_as_plugin_api() for marking types as plugin API,
- used for plugin-internal types like enums, flags, pad
- subclasses, boxed types, and such.
+- this section will be filled in in due course
Possibly Breaking Changes
-- GstVideo: the canonical list of raw video formats (for use in caps)
- has been reordered, so video elements such as videotestsrc or
- videoconvert might negotiate to a different format now than before.
- The new format might be a higher-quality format or require more
- processing overhead, which might affect pipeline performance.
-
-- mpegtsdemux used to wrongly advertise H.264 and H.265 video
- elementary streams as alignment=nal. This has now been fixed and
- changed to alignment=none, which means an h264parse or h265parse
- element is now required after tsdemux for some pipelines where there
- wasn’t one before, e.g. in transmuxing scenarios (tsdemux ! tsmux).
- Pipelines without such a parser may now fail to link or error out at
- runtime. As parsers after demuxers and before muxers have been
- generally required for a long time now it is hoped that this will
- only affect a small number of applications or pipelines.
-
-- The Android opensles audio source and sink used to have hard-coded
- buffer-/latency-time values of 20ms. This is no longer needed with
- newer Android versions and has now been removed. This means a higher
- or lower value might now be negotiated by default, which can affect
- pipeline performance and latency.
