MMUSIC and RTCWeb, I would like to make you aware of an ongoing discussion around how the SDP attribute for RTP header extensions (a=extmap) should work with BUNDLE. This is going on in the context of the update of RFC5285: https://datatracker.ietf.org/doc/draft-ietf-avtcore-rfc5285-bis/ Thread start: https://www.ietf.org/mail-archive/web/avt/current/msg17531.html This discussion started as result of the SDP expert reviewer who noticed that we failed to take muxing into account for the SDP attributes. And extmap is non-trivial and classified as special. So far we agreed that clarificatio is needed, but we have not yet agreed to what clarifications and their impact. So please review the discussion and contribute on the AVTCORE mailing list.
