[Live-devel] MP4V-ES

[stage.nexvision at laposte.net]

Hi all,

   I'm tried to understand what is done to the stream on the client side, before it is sent 
to the decoder, in the case where the stream is declared as MP4V/ES in the session 
description.

I've tried to use your code with mplayer, and it works out of the box, but as I don't 
understand the logic of the data flow inside MPlayer, so I don't understand what 
modification you're doing to the stream.

I've tried to reproduce this by saving the RTP packet (without headers, of course) 
content, until I get a Mark set to 1 (end of frame I guess). I'm almost I've saved them 
in the seq number order. Then I send this to avcodec decode function. 
I frame are decoded correctly, but P frame and B frame are not. 

I debugged the return of the avcodec_decode_video function, and it says it can find a 
picture in case of P frames. So I guess I've bad data somewhere, but I don't figure 
out where.

I would really appreciate if you could explain what is the data flow in the Live 
RTSP/RTP client, when the content is MP4V/ES. I've read the RTP/RTCP/RTSP 
standard but I guess I'm missing something.

Thanks.
Cyril
