Bug 275157 – [GStreamer][WebRTC] Missing a=msid in offer after setting codec preferences

• Status: RESOLVED
• Resolution: FIXED
• Component: WebRTC

[Carlos Bentzen]

This test fails:

let pc = new RTCPeerConnection();
let stream = await navigator.mediaDevices.getUserMedia({ video: true });
let track = stream.getVideoTracks()[0];
pc.addTrack(track, stream);
pc.getTransceivers()[0].setCodecPreferences([{mimeType: "video/VP8", clockRate: 90000}]);
let offer = await pc.createOffer();
assert_true(offer.sdp.includes(`a=msid:${stream.id} ${track.id}`), 'offer SDP includes a=msid line');
