H.263 video on RTP stream

Postby zhao0419 » 17 Nov 2008 08:58

I redirect Innomedia 5550 H.263 stream to Darwin streaming server . And I use VLC and quicktime to see this video by visiting SDP.
SDP is below:
v=0\r\n
s=-\r\n
c=IN IP4 135.252.48.49\r\n
m=video 7080 RTP/AVP 97\r\n
b=AS:256\r\n
a=rtpmap 34 H263/90000\r\n
a=framerate:15\r\n"
a=rtcp:7081\r\n
a=fmtp:34 CIF=2 QCIF=2/MaxBR=2560\r\n\r\n
Then I will see nothing.VLC will fail to connect streaming server. Quicktime will recevie real time stream but fails to
display H.263 video .


I send H.264 instead .SDP is below:
v=0\r\n
s=-\r\n
c=IN IP4 135.252.48.49\r\n
m=video 7080 RTP/AVP 97\r\n
b=AS:256\r\n
a=framerate:15\r\n"
a=rtcp:7081\r\n
a=rtpmap 97 H264/90000\r\n
a=fmtp:97 CIF=2 QCIF=2/MaxBR=2560 profile-level-id=420015; packetization-mode=1; parameter-add=0; max-rcmd-nalu-size=1530\r\n\r\n
But I can only see a picture that doesnot move using VLC .
I see those messages in VLC.
main warning: late picture skipped (558389)
ffmpeg error: more than 5 seconds of late video -> dropping frame (computer too slow ?)


I am not familiar with H.264 and H.263 codec . please help me
