Changelog:

0.11.0 - 2023-08-10

Changed

Updated MSRV to 1.70.
Compatible with gtk-rs 0.18 and gstreamer-rs 0.21.
awstranscriber: Move to HTTP2-based API via the aws-sdk-transcribestreaming
crate instead of our own implementation around the WebSocket API.


Added

webrtcsink: Add AWS KVS signaller and corresponding aws-kvs-webrtcsink
element.
awstranscriber / transcriberbin: Add support for translations and outputting
transcriptions from a single audio stream in multiple languages at once.
gstwebrtc-api: JavaScript API for interacting with the default signalling
protocol used by webrtcsink / webrtcsrc.
cea608to708: New element for converting CEA608 to CEA708 closed captions.
webrtcsink: Expose the signaller as property and allow implementing a
custom signaller by connecting signal handlers to the default signaller.
webrtcsink: Add support for pre-encoded streams.
togglerecord: Add support for non-live input streams.
webrtcsink: New whipwebrtcsink that implements WHIP around webrtcsink.
The existing whipsink still exists but will sooner or later be deprecated.
webrtcsink: Add LiveKit signaller and corresponding livekitwebrtcsink
element.

Cargo.lock is temporarely added as a patch to aid in compiling, see upstream bug report
