109 GStreamer Rust Bindings and Rust Plugins
111 The GStreamer Rust bindings are released separately with a different
112 release cadence that’s tied to gtk-rs, but the latest release has
113 already been updated for the upcoming new GStreamer 1.20 API.
115 gst-plugins-rs, the module containing GStreamer plugins written in Rust,
116 has also seen lots of activity with many new elements and plugins.
118 What follows is a list of elements and plugins available in
119 gst-plugins-rs, so people don’t miss out on all those potentially useful
120 elements that have no C equivalent.
122 - FIXME: add new elements
126 - audiornnoise: New element for audio denoising which implements the
127 noise removal algorithm of the Xiph RNNoise library, in Rust
128 - rsaudioecho: Port of the audioecho element from gst-plugins-good
129 rsaudioloudnorm: Live audio loudness normalization element based on
130 the FFmpeg af_loudnorm filter
131 - claxondec: FLAC lossless audio codec decoder element based on the
132 pure-Rust claxon implementation
133 - csoundfilter: Audio filter that can use any filter defined via the
134 Csound audio programming language
135 - lewtondec: Vorbis audio decoder element based on the pure-Rust
136 lewton implementation
140 - cdgdec/cdgparse: Decoder and parser for the CD+G video codec based
141 on a pure-Rust CD+G implementation, used for example by karaoke CDs
142 - cea608overlay: CEA-608 Closed Captions overlay element
143 - cea608tott: CEA-608 Closed Captions to timed-text (e.g. VTT or SRT
145 - tttocea608: CEA-608 Closed Captions from timed-text converter
146 - mccenc/mccparse: MacCaption Closed Caption format encoder and parser
147 - sccenc/sccparse: Scenarist Closed Caption format encoder and parser
148 - dav1dec: AV1 video decoder based on the dav1d decoder implementation
150 - rav1enc: AV1 video encoder based on the fast and pure-Rust rav1e
151 encoder implementation
152 - rsflvdemux: Alternative to the flvdemux FLV demuxer element from
153 gst-plugins-good, not feature-equivalent yet
154 - rsgifenc/rspngenc: GIF/PNG encoder elements based on the pure-Rust
155 implementations by the image-rs project
159 - textwrap: Element for line-wrapping timed text (e.g. subtitles) for
160 better screen-fitting, including hyphenation support for some
165 - reqwesthttpsrc: HTTP(S) source element based on the Rust
166 reqwest/hyper HTTP implementations and almost feature-equivalent
167 with the main GStreamer HTTP source souphttpsrc
168 - s3src/s3sink: Source/sink element for the Amazon S3 cloud storage
169 - awstranscriber: Live audio to timed text transcription element using
170 the Amazon AWS Transcribe API
174 - sodiumencrypter/sodiumdecrypter: Encryption/decryption element based
176 - togglerecord: Recording element that allows to pause/resume
177 recordings easily and considers keyframe boundaries
178 - fallbackswitch/fallbacksrc: Elements for handling potentially
179 failing (network) sources, restarting them on errors/timeout and
180 showing a fallback stream instead
181 - threadshare: Set of elements that provide alternatives for various
182 existing GStreamer elements but allow to share the streaming threads
183 between each other to reduce the number of threads
184 - rsfilesrc/rsfilesink: File source/sink elements as replacements for
185 the existing filesrc/filesink elements

268 … and many others who have contributed bug reports, translations, sent
269 suggestions or helped testing.
273 After the 1.20.0 release there will be several 1.20.x bug-fix releases
274 which will contain bug fixes which have been deemed suitable for a
275 stable branch, but no new features or intrusive changes will be added to
276 a bug-fix release usually. The 1.20.x bug-fix releases will be made from
277 the git 1.20 branch, which will be a stable branch.
281 1.20.0 is scheduled to be released around October/November 2021.
285 Our next major feature release will be 1.22, and 1.21 will be the
286 unstable development version leading up to the stable 1.22 release. The
287 development of 1.21/1.22 will happen in the git main branch.
289 The plan for the 1.22 development cycle is yet to be confirmed.
291 1.22 will be backwards-compatible to the stable 1.20, 1.18, 1.16, 1.14,
292 1.12, 1.10, 1.8, 1.6, 1.4, 1.2 and 1.0 release series.
