H264 receiving problem with VLC

[silvara]

Hi all;

I search the forum but unfortunately i couldnt find the answer for my problem.
My application creates rtp socket from ip 192.168.0.135 to 192.168.0.165.It carries video packages with H264 format.
I want to receive this stream from vlc at 192.168.0.165. So i create below sdp file;

Code: Select all

v=0 o=- 597327894206 2 IN IP4 192.168.0.165 s=NONE t=0 0 c=IN IP4 192.168.0.165 m=video 14444 RTP/AVP 98 b=AS:28 a=rtpmap:98 H264/90000

When i load it , VLC displays only one frame and it stops. I also tried to stop and play , it still shows only one fram and stops.

What might be the problem ? Your help will be appriciated

I have simular problem.

I get this message about a hundred times, when trying to play an rtsp stream from a VLC server.

Code: Select all

packetizer_h264 warning: waiting for SPS/PPS

I guess VLC does not stream rtsp with h264 properly. If you figure out anything about the problem, I would be interested in the solution.

[gooral]

you should insert pps and sps information to sdp file or send it in rtp packet.

I think it is basically a bug in vlc that vlc does not send the pps/sps information with the first i-frame. So if the video only has one iframe the movie will never display.
