[Tim-Philipp Müller]

The GStreamer team is thrilled to announce a new major feature release
of your favourite cross-platform multimedia framework!

As always, this release is again packed with new features, bug fixes
and many other improvements.

The 1.20 release series adds new features on top of the 1.18 series and
is part of the API and ABI-stable 1.x release series of the GStreamer
multimedia framework.

Highlights:

  - Development in GitLab was switched to a single git repository
    containing all the modules

  - GstPlay: new high-level playback library, replaces GstPlayer

  - WebM Alpha decoding support

  - Encoding profiles can now be tweaked with additional
    application-specified element properties

  - Compositor: multi-threaded video conversion and mixing

  - RTP header extensions: unified support in RTP depayloader and
    payloader base classes

  - SMPTE 2022-1 2-D Forward Error Correction support

  - Smart encoding (pass through) support for VP8, VP9, H.265 in
    encodebin and transcodebin

  - Runtime compatibility support for libsoup2 and libsoup3 (libsoup3
    support experimental)

  - Video decoder subframe support

  - Video decoder automatic packet-loss, data corruption, and keyframe
    request handling for RTP / WebRTC / RTSP

  - mp4 and Matroska muxers now support profile/level/resolution
    changes for H.264/H.265 input streams (i.e. codec data
    changing on the fly)

  - mp4 muxing mode that initially creates a fragmented mp4 which is
    converted to a regular mp4 on EOS

  - Audio support for the WebKit Port for Embedded (WPE) web page
    sourceelement

  - CUDA based video color space convert and rescale elements and
    upload/download elements

  - NVIDIA memory:NVMM support for OpenGL glupload and gldownload
    elements

  - Many WebRTC improvements

  - The new VA-API plugin implementation fleshed out with more decoders
    and new postproc elements

  - AppSink API to retrieve events in addition to buffers and buffer
    lists

  - AppSrc gained more configuration options for the internal queue
    (leakiness, limits in buffers and time, getters to read current
    levels)

  - Updated Rust bindings and many new Rust plugins

  - Improved support for custom minimal GStreamer builds

  - Support build against FFmpeg 5.0

  - Linux Stateless CODEC support gained MPEG-2 and VP9
