GStreamer 1.20 Release Notes
GStreamer 1.20 has not been released yet. It is scheduled for release
around October/November 2021.
1.19.x is the unstable development version that is being developed in
the git main branch and which will eventually result in 1.20, and 1.19.2
is the current development release in that series
It is expected that feature freeze will be in early October 2021,
followed by one or two 1.19.9x pre-releases and the new 1.20 stable
release around October/November 2021.
1.20 will be backwards-compatible to the stable 1.18, 1.16, 1.14, 1.12,
1.10, 1.8, 1.6,, 1.4, 1.2 and 1.0 release series.
See https://gstreamer.freedesktop.org/releases/1.20/ for the latest

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 upcoming new GStreamer 1.20 API.
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.
- FIXME: add new elements
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

Stable 1.20 branch
After the 1.20.0 release there will be several 1.20.x bug-fix releases
which will contain bug fixes which have been deemed suitable for a
stable branch, but no new features or intrusive changes will be added to
a bug-fix release usually. The 1.20.x bug-fix releases will be made from
the git 1.20 branch, which will be a stable branch.
1.20.0
1.20.0 is scheduled to be released around October/November 2021.
Schedule for 1.22
Our next major feature release will be 1.22, and 1.21 will be the
unstable development version leading up to the stable 1.22 release. The
development of 1.21/1.22 will happen in the git main branch.
The plan for the 1.22 development cycle is yet to be confirmed.
1.22 will be backwards-compatible to the stable 1.20, 1.18, 1.16, 1.14,
1.12, 1.10, 1.8, 1.6, 1.4, 1.2 and 1.0 release series.
