Hi,
If you are receiving an INVITE with a SDP offer containing this video
stream (along an audio stream not shown):
m=video 6964 RTP/AVP 109
a=rtpmap:109 H264/90000
a=fmtp:109 profile-level-id=42800d
And you want to decline the video stream, what is the right/best way to
refuse it:
1.
m=video 0 RTP/AVP 109
port = 0, leaving the RTP dynamic codec 109 but no related rtpmap/fmtp.
2.
m=video 0 RTP/AVP 109
a=rtpmap:109 H264/90000
a=fmtp:109 profile-level-id=42800d
port = 0, leaving the RTP dynamic codec 109 including the corresponding
rtpmap/fmtp in the offer.
3.
m=video 0 RTP/AVP 34
port = 0, changing the RTP codec to a known static one (H263).
Regards.
