<div>Are these files both non-empty?</div>
<div><br></div>
<div>If these files are both empty, then that shows that you are not
receiving RTP packets from your server, most likely because you have a
firewall - between the client and the server - that is bocking RTP
packets. In that case, either fix your firewall, or use the
"-t" option to openRTSP, to request RTP-over-TCP
streaming.</div>

<div><br></div>
<div>You can't. VLC cannot play MPEG-4 video Elementary Stream
files.</div>
<div><br></div>

one?</blockquote>
</blockquote>
<div><br></div>
<div>You can't. VLC cannot PLAY MPEG-4 audio (AAC) Elementary
Stream files.</div>
<div><br></div>
<div>However, VLC *should* be able to play the stream directly - i.e.,
enter the "rtsp://..." URL directly into VLC, and don't use
"openRTSP" at all.</div>
<div><br></div>
<blockquote type="cite" cite>
<blockquote> I also tried to rename it as "test.aac" and
stream it with "testOnDemandRTSP.exe" application, but it
doesn't seem to work.</blockquote>
</blockquote>
<div><br></div>
<div>That won't work, because the file was not in ADTS format.</div>

</blockquote>
<div><br></div>
<div>When using the "-4" option, you need to make sure that
the stream runs all the way through. You can't just
<control>-c it. You should also use the "-w",
"-h" and "-f" options.</div>
<div><br></div>
<div>If you are still not receiving any data, then - as noted above -
you are probably behind a firewall. If so, then add the
"-t" option.</div>
