What: RTCRtpTransceiver is a central part of the w3c webrtc API
(https://www.w3.org/TR/webrtc/) and JSEP spec
(https://tools.ietf.org/html/draft-ietf-rtcweb-jsep). This is a
significant addition to the webrtc API, and entails a rework of the
internals (it is not practical to hide this rework code behind a pref).
This work will apply to all platforms and in all situations where
RTCPeerConnection is supported now.
Why: This has been in the relevant specifications for a year and a
half, is considered "done" from a spec perspective, but still hasn't
been implemented. Given that this spec involves browser-to-browser
interop, it is vital that there be some running code out there.
Where: https://bugzilla.mozilla.org/show_bug.cgi?id=1290948
When: My intent is to land this early in the 58 release cycle.
Our existing test suite will do a good job of covering the internal
rework, and I have written some additional test-cases to cover the new
API. web-platform-tests has some coverage of the new API also (in
https://github.com/w3c/web-platform-tests/blob/master/webrtc/RTCPeerConnection-addTransceiver.html
and
https://github.com/w3c/web-platform-tests/blob/master/webrtc/RTCPeerConnection-getTransceivers.html).
Best regards,
Byron Campen
