[Live-devel] mpeg-4 multicast?

[Li bz]

Hi, Ross,

I run the testMPEG4VideoStream.exe, there is some
problems I cannot understand.

I got the test.m4v video file as you told throught
openRTSP, but I cannot play 
this file directly by VLC, QT, or realPlayer. I don't
understand much MPEG-4 specification, can you give me
some idea by which specification does this file 
is made or is there tools to analyze this file?

Another problem is : When I tried to broadcast this
file, I cannot use VLC as 
client to receive video by RTP/UDP, however, when I
tried to receive through RTSP.
I think testMPEG4VideoStream.exe should be a broadcast
program with RTSP server 
built-in, is that right? How can I use VLC to receive
the video through multicast?

Thank you very much.
