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?
Thanks for your answer,
Javi
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
