[Live-devel] H264 over RTP/RFC 3984

[Larry Cui]

I'm using RTSP, I did not use sdp file, but through RSTP DESCIBE.  If the PPS is a little bit different from SDP in RTSP, is it a problem? I really could not find other issue.
When I open VLC, I only input rtsp://169.254.1.5, nothing else. Is this a problem? I'm reading the source code for VLC, seems they need a track id.


Note : live555 warning: no data received in 10s. Switching to TCP


Here's the VLC message

My stream complies with RFC 3984, and I insert SPS and PPS at the front of every I frame.
The problem is VLC always gives the message:  "live555 no data received with 10s" than rtsp tear down . I'm pretty sure the rtp stream is there and rtp port number is right. Why VLC cannot receive the stream and decode it as rtp/h264?

In order for VLC to be able to play the stream, VLC needs a SDP description, so that it will know (i) that the stream is H.264, and (ii) which RTP payload format code it is using.

Are you giving VLC a SDP description - either directly (as a file), or indirectly, using RTSP?
