The following commits were just pushed by aboba to https://github.com/w3c/webrtc-pc: * Fix setCodecPreferences note regarding offer/answer negotiation. Fixes #1838. The note said that, even if codec preferences are set, the list of codecs in the answer will be a subset of those in the offer. Which JSEP required before, but now does not: [T]he media formats in the answer MUST include at least one format that is present in the offer, but MAY include formats that are locally supported but not present in the offer. So now, the subset rule is only a SHOULD in RFC3264, and not a MUST in JSEP. So although most implementations are expected to honor the "SHOULD", implementations can technically offer codecs in the answer that were not in the offer. Which is now clarified in this note, with a brief example. by Taylor Brandstetter https://github.com/w3c/webrtc-pc/commit/5d6d175819a4ab622715472c6c7a710aa259b522 * Rewording note per Bernard's suggestion by Taylor Brandstetter https://github.com/w3c/webrtc-pc/commit/7308fbec8c5bab6302639d466327290a46326b7c * Merge pull request #1844 from taylor-b/issue_1838_setCodecPreferences_note Fix setCodecPreferences note regarding offer/answer negotiation. by Bernard Aboba https://github.com/w3c/webrtc-pc/commit/8ec737358755e47c81dcd06f7f2c5792cd728565
