<div>You should first try running the *original*, *unmodified*
testMPEG4VideoStreamer application, using a single file - named
"test.m4e" - as input. Only when you have this working
should you consider modifying the code and/or writing your own server
application.</div>

<div><br></div>
<div>I can't, because ***VLC is not our software***.</div>
<div><br></div>
<div>Instead, you should first try playing/recording the stream (as
served by the *original*, *unmodified* testMPEG4VideoStreamer
application) using our "openRTSP" RTSP client application
(see <http://www.live555.com/openRTSP/>).</div>
<div><br></div>
<div>If "openRTSP" fails to record any data, then the
problem may be because you don't have IP multicast routing between
your server and client, or else a firewall that blocks UDP. (See
<http://www.live555.com/liveMedia/faq.html#openRTSP-empty-files<span
></span>>) You should instead first try running the server
and client on the same LAN.</div>
<div><br></div>
<div>If "openRTSP" records data OK (i.e., writes non-empty
files), then the problem is likely that VLC is having trouble decoding
your video. In that case, you need to report the problem on a
VLC mailing list instead.</div>
