V3C specific parameters can't be used with the 2D video media lines #22

Closed laurilo closed 5 months ago

laurilo commented 6 months ago

For the SDP encoding, the description in section 9.1.2 for the V3C video components doesn’t work. When you send the SDP

       m=video 49170 RTP/AVP 99
       a=rtpmap:99 H265/90000
       a=fmtp:99 sprop-max-don-diff=0;
                 v3c-unit-header=EAAAAA==

you are negotiating the payload “video/H265”, not “video/V3C”, and that payload is defined by RFC 7798. Unless you are updating the existing RFCs, this document can’t add parameters to video/H264 et al, only define video/V3C and its parameters.

Introduced a new v3cfmtp attribute that can be used to carry V3C specific medi format parameters. Addressd in commit https://github.com/laurilo/draft-ilola-avtcore-rtp-v3c/commit/b4f0e9775c14a543ab8780142005b514d410e024
