Hi,

2008/6/3 Anders Broman <[email protected]>:
Hi,
What protocol is used to set up the stream? is SDP used?

Yes, the video on demand procedure is started with a RTSP packet exchange with a SDP file with the corresponding parameters. It is properly decoded with Wireshark.
 
What Mime type is it MP4V-ES other?

As said before, I have tried with elementary and program streams. In the last case, I have mpeg4-generic MIME type for audio and MP4V-ES for video.

What do you want decoded?

I would like to catch information regarding which frames are being streamed (I, P or B).

Anyway, have you succeed in decoding this kind of information from the UDP/RTP/MP4 packet stream?
 
Regards
Anders


Thanks for your answer,
Javi

Subject: [Wireshark-users] Does Wireshark support MP4 payload decoding?

Hi all,

I have searched for this issue in the archive but the question was not answered yet, so here I am.

I would like to know if Wireshark does support MP4 packets decoding. I am using version 1.0.0 in an Ubuntu Linux 2.6.24-17. I am also using VideoLAN VLC on the VOD server side and on the player client side. I have tried with originally mp4 encoded videos, on-the-fly decoded ones from MPEG-1 and with elementary video streams. They work perfectly (I can stream and watch the videos) but when I try to decode the UDP/RTP packets with Wireshark the payload is marked as unknown. With MPEG-1 it works properly as soon as I have tested.

So, has anyone succeed in decoding the RTP payload for a MP4 stream (if not with VLC, with which streaming software?)?


Thank you all,
Javi
