Well, I tried that but didn't have much luck.  I got a file of captured
video and used it with testOnDemandRTSPServer and live555MediaServer
without much luck.  VLC debug console gives me something like this:

===================================================

I honestly have no idea what it is doing there.  One interesting tidbit is
if I get the same file that I was feeding the RTSP server and try to open
it on the VLC commandline with -vvv, I get:

===================================================

Note what VLC tried to use:
[00000315] main packetizer debug: removing module "packetizer_mpegvideo"
[00000301] main demuxer debug: removing module "mpgv"
[00000295] main access debug: removing module "access_file"
[00000338] main decoder debug: removing module "libmpeg2"

So the packetizer, demuxer, and decoder were all for MPEG 1/2!  So I guess
it doesn't get enough information from the file to know it is MPEG-4.  I
wonder if that is related to my problems?

If people want to take a look at what the video files look like, I put a
sample file (500k) here: http://www.orbitfiles.com/download/id1063667217

If anyone knows what I need to do, I'd appreciate the help.  Thanks!

Jeff
