The extmap-allow-mixed SDP attribute signals that one- and two-byte RTP header extensions can be mixed. In practice, this also means that WebRTC will support two-byte RTP header extensions when this is signaled by both peers. Bug: webrtc:9985 Change-Id: I80a3f97bab162c7d9a5acf2cae07b977641c039d Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/197943 Commit-Queue: Emil Lundmark <lndmrk@webrtc.org> Reviewed-by: Erik Språng <sprang@webrtc.org> Reviewed-by: Harald Alvestrand <hta@webrtc.org> Cr-Commit-Position: refs/heads/master@{#33036}
