Playing h264 with cayenne_1_5_0 over RTP

Hi All,

I am doing some tests with Visual Studio h264 binaries
available in 
datatype-dist.
Local file playback looks to work but rtp stream playback
does not.

An assertion occurs in H264Decoder/H264VLDHeaders.cpp line
2454, the 
failing expression is "0 !=
m_VLDCurrentPicture".

Here is the sdp file passed to Helix

v=0
o=- 1 1 IN IP4 127.0.0.1
s=mp4broadcaster
e=NONE
c=IN IP4 224.0.0.1/2
t=0 0
b=RR:0
m=video 20000 RTP/AVP 96
b=AS:200
a=control:trackID=2
a=rtpmap:96 H264/90000
a=fmtp:96 profile-level-id=674d00; 
sprop-parameter-sets=Z00AKJp0FidCAB6MUAOThsUI,aO48gA==;
packetization-mode=1

QuickTime is able to play the stream from this file.

Thanks,
David

Please file a bug.
Enter cayenne as the keyword, add milko and ehyche to bug CC
list and 
assign to pankajgupta.

It is important to include rtsp repro link if at all
possible.

Thanks,
Milko

I only worked on the local playback part of the H.264
decoder. I believe
Pankaj Gupta worked on the rtsp / depacketization part, and
it sounds
like this has a problem in this case. He can correct me if I
am wrong.

Is your rtsp stream available?

Karl.

It's not a RTSP stream, it's a local multicast RTP stream
generated with 
mpeg4ip test tool (mp4broadcaster).
