[Live-devel] VLC does not display any video when streaming with testMPEG4VideoStreamer

That's strange.  I successfully tested testMPEG4VideoStreamer and VLC 
(version 1.1.3) on Mac OS X (with both running on the same machine, 
though it would also have worked over a (multicast-capable) network).

In any case, VLC is not our software, so if you see any problems with 
VLC - but not with "openRTSP" (our own RTSP/RTP client) running on 
the *same* computer - then you should report it to a VLC mailing list 
instead.

This is the problem that you should address first.  I have never 
heard of anyone else encountering this problem before, so I suspect 
that you may have a problem with some binaries being out of date.  I 
suggest removing *all* LIVE555 binary files, and compiling linking 
everything from scratch.

In any case, I suggest doing your testing with Linux first (i.e., 
with "testMPEG4VideoStreamer" and "openRTSP"), as Linux software is 
easier to build then Windows.  In particular, I suggest testing in 
the following order:
1/ "testMPEG4VideoStreamer" running on a Linux computer; "openRTSP" 
running on the same Linux computer.
2/ "testMPEG4VideoStreamer" running on a Linux computer; "openRTSP" 
running on a different Linux computer (but on the same 
multicast-connected network).
3/ "testMPEG4VideoStreamer" running on a Linux computer; "openRTSP" 
running on a Windows computer (on the same multicast-connected 
network).
4/ "testMPEG4VideoStreamer" running on a Linux computer; "VLC" 
running on a Windows computer (on the same multicast-connected 
network).

If 1/ through 3/ work OK, but not 4/, then you have a problem with 
VLC (and thus not a problem for this mailing list).  However, in this 
case I would also test VLC running on a Mac OS X computer, as that 
works OK for me.
