Deprecation warning on RTC_PEER_CONNECTION_CONFIG sdpSemantics value plan-b #66

Closed Christian-Sesta closed 2 years ago

Christian-Sesta commented 3 years ago

My team noticed this warning appear in Chrome DevTools.

--

[Deprecation] Plan B SDP semantics, which is used when constructing an RTCPeerConnection with {sdpSemantics:"plan-b"}, is a legacy version of the Session Description Protocol that has severe compatibility issues on modern browsers. The standardized SDP format, "unified-plan", has been used by default since M72 (January, 2019). Dropping support for Plan B is targeted for M93 (Canary: July 15, 2021; Stable: August 24, 2021).

--

The cause seems to be connect-rtc-js using plan-b semantics instead of unified-plan. 

connect-rtc-js/src/js/rtc_const.js
export const RTC_PEER_CONNECTION_CONFIG = {
 iceTransportPolicy: 'relay',
 rtcpMuxPolicy: 'require',
 bundlePolicy: 'balanced',
 sdpSemantics: 'plan-b'
};

Any update on this issue? The deprecation has been there for a long time, and from what I can tell not only affects this library, but also the out-of-the-box CCP. Now that it's broken in Chrome Canary and could cause wide breakage if introduced to stable Chrome, is there any schedule available for when Plan B might be removed from this library? Are there backend changes that need to happen that this library is waiting on?

Looks like it's removed in the master branch as of 3 days ago, but they haven't cut a release yet. https://github.com/aws/connect-rtc-js/commit/262e9d947942c044835597c109c70555fb3b9d8d

Looks like they have cut the new release @marktheunissen , @aztalbot. They also sent out emails about this change to all aws instances as I got them yesterday. Going to close this ticket for them now.
