[Live-devel] Can't stream an mpeg-2 file

Remember that "testMPEG1or2VideoReceiver" outputs its received MPEG video 
data to *standard output*.  That means that - if you don't redirect the 
output to a file - it will go to the console.  That's why you're seeing 
'random' data on your console.

So, to get the MPEG video output into a file, run
         testMPEG1or2VideoReceiver > foo.mpg
and then your file "foo.mpg" will contain the MPEG Elementary Stream video 
data.

Alternatively, you can run a standards-based media player client - such as 
VLC <http://www.videolan.org/vlc/> - to view the video stream.  You can do 
this by having the media player open the file "testMPEG1or2Video.sdp" 
(which is present in the "testProgs" directory).

This is because your file was not a true MPEG Program Stream 
file.  Instead, it is a "VOB" file (which is similar to a Program Stream 
file, except that the audio stream uses the AC3 audio format, rather than 
the MPEG audio format).

To stream such a file, use the "vobStreamer" test program (see 
<http://www.live.com/vobStreamer/> - *not* 
"testMPEG1or2VideoStreamer".  Again, you can use the "VLC" media player to 
play this stream (using the "rtsp://" URL that "vobStreamer" prints out).
