can't stream h264 over RTP, but success with RTSP

[salexsh]

hi,

i have encountered a problem streaming H264 over RTP. when try to do this the VLC client does not recognize the stream.
However when i try to do this over RTSP it works great.
the streaming is made with Live555 test program.
After reviewing the content of the packets sent (RTP content) it is the same.
so i probably have to configure somehow the VLC client to receive the stream?
any suggestions to what am i doing wrong?
VLC versions i have tried are 0.8.6b and 0.9, will newer versions help at this, where there specific upgrades for H264 RTP streaming?

Thanks all,
Alex.

Hi all,

We have mannaged to solve this problem in the following manner:
1. intercept the SDP returning message from the client to the server.
2. copy the content of this message into a text file named <*>.sdp
3. open the sdp file from the vlc client.
4. start streaming (no need to open network stream, the sdp file intercepted allready contains stream info and locks the client onto a stream).

thanks al
Alex.

How have you tried that h264/rtp streaming that it doesn't work? if you mean h264 in ts-muxed on rtp-stream then yes, its known bug and fixed in 1.1.1

That limitation comes from the RTP and H.264 payload format specifications. There is no way for VLC (or any other player) to know the codec parameter without a proper SDP. With RTSP, the SDP is conveyed in the signaling (the DESCRIBE request).
