[Live-devel] H264 video frame problem

[Tao Wu]

Hi,

I am working on a H264 video framer to stream a h264 file. I did some
search on the forum and found Mike did some solid work before.
Basically, I wrote a H264 videostream class, which are almost a
re-make of Mike's work. However, I have problems to play the stream on
VLC. The VLC player will collapse when opening the rtsp stream.

Interestingly, I can use openRTSP test program to receive the stream
and stored it into a file. Then the VLC can play the stored file
locally. I don't know whether it is a problem of my code or VLC
(verylikely it is my code problem).

I attached the RTSP response from openRTSP test program. I greatly
appreciate if anyone can take a look to see what I missed.

Thanks a lot.

Best Regards,
Tao
