suppose I want to make a video call, so I send the
following SDP description. The bandwidth for audio can be determined by the
codec, but how to determine the bandwidth for h261 video? it is 384k, 256k or
other. and it is CIF or QCIF?
m=audio 8766 RTP/AVP 0 4 8
a=rtpmap:0 pcmu/8000/1
a=rtpmap:4 g723/8000/1 a=rtpmap:8 pcma/8000/1 m=video 23738 RTP/AVP 31 a=rtpmap:31 h261/90000/1 |
