 Major new features and changes
 
-Noteworthy new API
+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
+
+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.
 
--   FIXME
+-   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

+    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!
 
 New element features and additions
 
--   FIXME
+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
+        mode
+    -   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.
+
+-   uvch264src now comes with a device provider to advertise available
+    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 and library moves
 
--   FIXME
+-   There were no plugin moves or library moves in this cycle.
+
+-   The rpicamsrc element was moved into -good from an external
+    repository on github.
 
 Plugin removals
 
-The following plugins have been removed from gst-plugins-bad:
+The following elements or plugins have been removed:
 
--   FIXME
+-   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.
 
-Miscellaneous API additions
+-   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.
 
--   FIXME
+Miscellaneous API additions
 
-Miscellaneous performance and memory optimisations
+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)
+
+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
@@ -69,63 +1073,654 @@ The following list is only a small snapshot of some of the more
 interesting optimisations that haven’t been mentioned in other contexts
 yet:
 
--   FIXME
+-   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.
 
-GstPlayer
+-   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.
 
--   FIXME
+-   webrtcbin now exposes a latency property for configuring the
+    internal rtpjitterbuffer latency and buffering when receiving
+    streams.
 
-Miscellaneous changes
+-   webrtcbin now only synchronises the RTP part of a stream, allowing
+    RTCP messages to skip synchronisation entirely.
 
--   FIXME
+-   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
 
--   FIXME
+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.
 
 Tracing framework and debugging improvements
 
--   FIXME
+-   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
 
 Tools
 
--   FIXME
+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).
 
 GStreamer RTSP server
 
--   FIXME
+-   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
 
 GStreamer VAAPI
 
--   FIXME
+-   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
+    quality-factor property for these modes. Support baseline profile as
+    constrained-baseline
+
+-   vaapih265enc:
+
+    -   support for main-444 and main-12 encoding profiles.
+    -   new max-qp property that sets the maximum quantization value.
+    -   support for ICQ and QBVR bitrate control mode, adding a
+        quality-factor property for these modes.
+    -   handle SCC profiles.
+    -   num-tile-cols and num-tile-row properties to specify the number
+        of tiles to use.
+    -   the low-delay-b property was deprecated and is now determined
+        automatically.
+    -   improved profile selection through caps.
+
+VAAPI Decoders
+
+-   Decoder surfaces are not bound to their context any longer and can
+    thus be created and used dynamically, removing the deadlock
+    headache.
+
+-   Reverse playback is now fluid
+
+-   Forward Region-of-Interest (ROI) metas downstream
+
+-   GLTextureUploadMeta uses DMABuf when GEM is not available. Now
+    Gallium drivers can use this meta for rendering with EGL.
+
+-   vaapivp9dec: support for 4:2:2 and 4:4:4 chroma type streams
+
+-   vaapih265dec: skip all pictures prior to the first I-frame. Enable
+    passing range extension flags to the driver. Handle SCC profiles.
+
+-   vaapijpegdec: support for 4:0:0, 4:1:1, 4:2:2 and 4:4:4 chroma types
+    pictures
+
+-   vaapih264dec: handle baseline streams as constrained-baseline if
+    possible and make it more tolerant when encountering unknown NALs
 
 GStreamer OMX
 
--   FIXME
+-   omxvideoenc: use new video encoder subframe API to push out slices
+    as soon as they’re ready
+
+-   omxh264enc, omxh265enc: negotiate subframe mode via caps. To enable
+    it, force downstream caps to video/x-h264,alignment=nal or
+    video/x-h265,alignment=nal.
+
+-   omxh264enc: Add ref-frames property
+
+-   Zynq ultrascale+ specific video encoder/decoder improvements:
+
+    -   GRAY8 format support
+    -   support for alternate fields interlacing mode
+    -   video encoder: look-ahead, long-term-ref, and long-term-freq
+        properties
 
 GStreamer Editing Services and NLE
 
--   FIXME
+-   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()
+
+        Quite a few validate tests have been implemented to check the
+        behavior for various demuxer/codec formats
+
+-   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.
+
+-   Added support for simple time remapping effects
 
 GStreamer validate
 
--   FIXME
+-   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 Python Bindings
 
--   FIXME
+-   Python 2.x is no longer supported
 
-GStreamer C# Bindings
+-   Support mapping buffers without any memcpy:
+
+    -   Added a ContextManager to make the API more pythonic
 
--   FIXME
+            with buf.map(Gst.MapFlags.READ | Gst.MapFlags.WRITE) as info:
+                info.data[42] = 0
 
-GStreamer Rust Bindings
+-   Added high-level helper API for constructing pipelines:
 
--   FIXME
+    -   Gst.Bin.make_and_add(factory_name, instance_name=None)
+    -   Gst.Element.link_many(element, ...)
 
-GStreamer Rust Plugins
+GStreamer C# Bindings
 
--   FIXME
+-   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

+GStreamer Rust Bindings and Rust Plugins
+
+The GStreamer Rust bindings are released separately with a different
+release cadence that’s tied to gtk-rs, but the latest release has
+already been updated for the new GStreamer 1.18 API, so there’s
+absolutely no excuse why your next GStreamer application can’t be
+written in Rust anymore.
+
+gst-plugins-rs, the module containing GStreamer plugins written in Rust,
+has also seen lots of activity with many new elements and plugins.
+
+What follows is a list of elements and plugins available in
+gst-plugins-rs, so people don’t miss out on all those potentially useful
+elements that have no C equivalent.
+
+Rust audio plugins
+
+-   audiornnoise: New element for audio denoising which implements the
+    noise removal algorithm of the Xiph RNNoise library, in Rust
+-   rsaudioecho: Port of the audioecho element from gst-plugins-good
+    rsaudioloudnorm: Live audio loudness normalization element based on
+    the FFmpeg af_loudnorm filter
+-   claxondec: FLAC lossless audio codec decoder element based on the
+    pure-Rust claxon implementation
+-   csoundfilter: Audio filter that can use any filter defined via the
+    Csound audio programming language
+-   lewtondec: Vorbis audio decoder element based on the pure-Rust
+    lewton implementation
+
+Rust video plugins
+
+-   cdgdec/cdgparse: Decoder and parser for the CD+G video codec based
+    on a pure-Rust CD+G implementation, used for example by karaoke CDs
+-   cea608overlay: CEA-608 Closed Captions overlay element
+-   cea608tott: CEA-608 Closed Captions to timed-text (e.g. VTT or SRT
+    subtitles) converter
+-   tttocea608: CEA-608 Closed Captions from timed-text converter
+-   mccenc/mccparse: MacCaption Closed Caption format encoder and parser
+-   sccenc/sccparse: Scenarist Closed Caption format encoder and parser
+-   dav1dec: AV1 video decoder based on the dav1d decoder implementation
+    by the VLC project
+-   rav1enc: AV1 video encoder based on the fast and pure-Rust rav1e
+    encoder implementation
+-   rsflvdemux: Alternative to the flvdemux FLV demuxer element from
+    gst-plugins-good, not feature-equivalent yet
+-   rsgifenc/rspngenc: GIF/PNG encoder elements based on the pure-Rust
+    implementations by the image-rs project
+
+Rust text plugins
+
+-   textwrap: Element for line-wrapping timed text (e.g. subtitles) for
+    better screen-fitting, including hyphenation support for some
+    languages
+
+Rust network plugins
+
+-   reqwesthttpsrc: HTTP(S) source element based on the Rust
+    reqwest/hyper HTTP implementations and almost feature-equivalent
+    with the main GStreamer HTTP source souphttpsrc
+-   s3src/s3sink: Source/sink element for the Amazon S3 cloud storage
+-   awstranscriber: Live audio to timed text transcription element using
+    the Amazon AWS Transcribe API
+
+Generic Rust plugins
+
+-   sodiumencrypter/sodiumdecrypter: Encryption/decryption element based
+    on libsodium/NaCl
+-   togglerecord: Recording element that allows to pause/resume
+    recordings easily and considers keyframe boundaries
+-   fallbackswitch/fallbacksrc: Elements for handling potentially
+    failing (network) sources, restarting them on errors/timeout and
+    showing a fallback stream instead
+-   threadshare: Set of elements that provide alternatives for various
+    existing GStreamer elements but allow to share the streaming threads
+    between each other to reduce the number of threads
+-   rsfilesrc/rsfilesink: File source/sink elements as replacements for
+    the existing filesrc/filesink elements

+    documentation module built with hotdoc (also see “Documentation
+    improvements” section below). Distributors should use the
+    documentation release tarball instead of trying to package hotdoc
+    and building the documentation from scratch.
+
+-   gst-plugins-bad now includes an internal copy of libusrsctp, as
+    there are problems in usrsctp with global shared state, lack of API
+    stability guarantees, and the absence of any kind of release
+    process. We also can’t rely on distros shipping a version with the
+    fixes we need. Both firefox and Chrome bundle their own copies too.
+    It is still possible to build against an external copy of usrsctp if
+    so desired.
+
+-   nvcodec no longer needs the NVIDIA NVDEC/NVENC SDKs available at
+    build time, only at runtime. This allows distributions to ship this
+    plugin by default and it will just start to work when the required
+    run-time SDK libraries are installed by the user, without users
+    needing to build and install the plugin from source.
+
+-   the gst-editing-services tarball is now named gst-editing-services
+    for consistency (used to be gstreamer-editing-services).
+
+-   the gst-validate tarball has been superseded by the gst-devtools
+    tarball for consistency with the git module name.
+
+gst-build
+
+gst-build is a meta-module and serves primarily as our uninstalled
+development environment. It makes it easy to build most of GStreamer,
+but unlike Cerbero it only comes with a limited number of external
+dependencies that can be built as subprojects if they are not found on
+the system.
+
+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.
+
+-   Add glib-networking as a subproject when glib is a subproject and
+    load gio modules in the devenv, tls option control whether to use
+    openssl or gnutls.
+
+-   git-worktree: Allow multiple worktrees for subproject branches
+
+-   Guard against meson being run from inside the uninstalled devenv, as
+    this might have unexpected consequences.
+
+-   our ffmpeg and x264 meson ports have been updated to the latest
+    stable version (you might need to update the subprojects checkout
+    manually though, or just remove the checkouts so meson checks out

 Cerbero

 on platforms where dependencies are not readily available, such as
 Windows, Android, iOS and macOS.
 
-Cerbero has seen a number of improvements:
+General improvements
+
+-   Recipe build steps are done in parallel wherever possible. This
+    leads to massive improvements in overall build time.
+-   Several recipes were ported to Meson, which improved build times
+-   Moved from using both GnuTLS and OpenSSL to only OpenSSL
+-   Moved from yasm to nasm for all assembly compilation
+-   Support zsh when running the cerbero shell command
+-   Numerous version upgrades for dependencies
+-   Default to xz for tarball binary packages. bz2 can be selected with
+    the --compress-method option to package.
+-   Added boolean variant for controlling the optimization level:
+    -v optimization
+-   Ship .pc pkgconfig files for all plugins in the binary packages
+-   CMake and nasm will only be built by Cerbero if the system versions
+    are unusable
+-   The nvcodec variant was removed and the nvcodec plugin is built by
+    default now (as it no longer requires the SDK to be installed at
+    build time, only at runtime)
+
+macOS / iOS
+
+-   Minimum iOS SDK version bumped to 11.0
+-   Minimum macOS SDK version bumped to 10.11
+-   No longer need to manually add support for newer iOS SDK versions
+-   Added Vulkan elements via MoltenVK
+-   Build times were improved by code-signing all build tools
+-   macOS framework ships all gstreamer libraries instead of an outdated
+    subset
+-   Ship pkg-config in the macOS framework package
+-   fontconfig: Fix EXC_BAD_ACCESS crash on iOS ARM64
+-   Improved App Store compatibility by setting LC_VERSION_MIN_MACOSX,
+    fixing relocations, and improved bitcode support
+
+Windows
+
+-   MinGW-GCC toolchain was updated to 8.2. It uses the Universal CRT
+    instead of MSVCRT which eliminates cross-CRT issues in the Visual
+    Studio build.
+-   Require Windows 7 or newer for running binaries produced by Cerbero
+-   Require Windows x86_64 for running Cerbero to build binary packages
+-   Cerbero no longer uses C:/gstreamer/1.0 as a prefix when building.
+    That prefix is reserved for use by the MSI installers.
+-   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
+    only supported building for 32-bit x86 using the MinGW toolchain.
+-   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
+    ~/.cerbero/cerbero.cbc where ~ is the MSYS homedir, not your Windows
+    homedir.
+-   New Windows-specific plugins: d3d11, mediafoundation, wasapi2
+-   Numerous compatibility and reliability fixes when running Cerbero on
+    Windows, especially non-English locales
+-   proxy-libintl now exports the same symbols as gettext, which makes
+    it a drop-in replacement
+-   New mapping variant for selecting the Visual Studio CRT to use:
+    -v vscrt=<value>. Valid values are md, mdd, and auto (default). A
+    separate prefix is used when building with either md (release) or
+    mdd (debug), and the outputted package will have +debug in the
+    filename. This variant is also used for selecting the correct Qt
+    libraries (debug vs release) to use when building with -v qt5 on
+    Windows.
+-   Support cross-compile on Windows to Windows ARM64 and ARMv7
+-   Support cross-compile on Windows to the Universal Windows Platform
+    (UWP). Only the subset of plugins that can be built entirely with
+    Visual Studio will be selected in this case. To do so, use the
+    config/cross-uwp-universal.cbc configuration, which will build
+    ARM64, x86, and x86_64 binaries linked to the release CRT, with
+    optimizations enabled, and debugging turned on. You can combine this
+    with -v vscrt=mdd to produce binaries linked to the debug CRT. You
+    can turn off optimizations with the -v nooptimization variant.
+
+Windows MSI installer
+
+-   Require Windows 7 or newer for running GStreamer
+-   Fixed some issues with shipping of pkg-config in the Windows
+    installers
+-   Plugin PDB debug files are now shipped in the development package,
+    not the runtime package
+-   Ship installers for 32-bit binaries built with Visual Studio
+-   Ship debug and release “universal” (ARM64, X86, and X86_64) tarballs
+    built for the Universal Windows Platform
+-   Windows MSI installers now install into separate prefixes when

+-   opensles: Remove hard-coded buffer-/latency-time values and allow
+    openslessink to handle 48kHz streams.
+
+-   photography interface and camera source: Add additional settings
+    relevant to Android such as: Exposure mode property, extra colour
+    tone values (aqua, emboss, sketch, neon), extra scene modes
+    (backlight, flowers, AR, HDR), and missing virtual methods for
+    exposure mode, analog gain, lens focus, colour temperature, min &
+    max exposure time. Add new effects and scene modes to Camera
+    parameters.
 
 macOS and iOS
 
--   FIXME
+-   vtdec can now output to Vulkan-backed memory for zerocopy support
+    with the Vulkan elements.
 
 Windows
 
--   toolchain upgrade
+-   d3d11videosink: new Direct3D11-based video sink with support for
+    HDR10 rendering if supported.
+
+-   Hardware-accelerated video decoding on Windows via DXVA2 /
+    Direct3D11 using native Windows APIs rather than per-vendor SDKs
+    (like MSDK for Intel or NVCODEC for NVidia). Plus modern Direct3D11
+    integration rather than the almost 20-year old Direct3D9 from
+    Windows XP times used in d3dvideosink. Formats supported for
+    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.
+
+-   d3d11: add d3d11convert, a color space conversion and rescaling
+    element using shaders, and introduce d3d11upload and d3d11download
+    elements that work just like glupload and gldownload but for D3D11.
+
+-   Universal Windows Platform (UWP) support, including official
+    GStreamer binary packages for it. Check out Nirbheek’s latest blog
+    post “GStreamer 1.18 supports the Universal Windows Platform” for
+    more details.
+
+-   systemclock correctness and reliability fixes, and also don’t start
+    the system clock at 0 any longer (which shouldn’t make any
+    difference to anyone, as absolute clock time values are supposed to
+    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.
+
+-   new dxgiscreencapsrc element which uses the Desktop Duplication API
+    to capture the desktop screen at high speed. This is only supported
+    on Windows 8 or later. Compared to the existing elements
+    dxgiscreencapsrc offers much better performance, works in High DPI
+    environments and draws an accurate mouse cursor.
+
+-   d3dvideosink was downgraded to secondary rank, d3d11videosink is
+    preferred now. Support OverlayComposition for GPU overlay
+    compositing of subtitles and logos.
+
+-   debug log output fixes, esp. with a non-UTF8 locale/codepage
+
+-   speex, jack: fixed crashes on Windows caused by cross-CRT issues
+
+-   gst-play-1.0 interactive keyboard controls now also work on Windows
+
+Linux
+
+-   kmssink: Add support for P010 and P016 formats
+
+-   vah264dec: new experimental va plugin with an element for H.264
+    decoding with VA-API. This novel approach, different from
+    gstreamer-vaapi, uses the gstcodecs library for decoder state
+    handling, which it is hoped will make for cleaner code because it
+    uses VA-API without further layers or wrappers. Check out Víctor’s
+    blog post “New VA-API H.264 decoder in gst-plugins-bad” for the full
+    lowdown and the limitations of this new plugin, and how to give it a
+    spin.
+
+-   v4l2codecs: introduce a V4L2 CODECs Accelerator. This plugin will
+    support the new CODECs uAPI in the Linux kernel, which consists of
+    an accelerator interface similar to DXVA, NVDEC, VDPAU and VAAPI. So
+    far H.264 and VP8 are supported. This is used on certain embedded
+    systems such as i.mx8m, rk3288, rk3399, Allwinner H-series SoCs.
+
+Documentation improvements
+
+-   unified documentation containing tutorials, API docs, plugin docs,
+    etc. all under one roof, shipped in form of a documentation release
+    tarball containing both devhelp and html documentation.
+
+-   all documentation is now generated using hotdoc, gtk-doc is no
+    longer used. Distributors should use the above-mentioned
+    documentation release tarball instead of trying to package hotdoc
+    and building the documentation from scratch.
+
+-   there is now documentation for wrapper plugins like gst-libav and
+    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.
+
+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.
