Given video encoded as mpeg2 transported over RTP from a Vbrick
appliance ( model 9110-4200), we need to record data as a series of
mpege2 TS chapter files of fixed duration that may subsequently be
played back using Live555 media server. We hope to support trick mode,
as well.<br>
<br>
Before realizing that the Vbrick mp2 appliance does not apparently
support RTSP ( although their mpeg4 device does) we had thought to use
OpenRTSP as a ( nearly complete) starting point for recording.<br>
<br>
We did find a note on playing back h323 directly from an RTP
transported stream using vlc and a hand generated sdp file:<br>
<br>
<blockquote>
<blockquote>
<blockquote>
<pre>v=0
o=- 7776 3 IN IP4 10.215.130.112
s=Test H263 stream
i=Parameters for the session streamed by "ChipsAhoyH263"
t=0 0
m=video 7776 <b
style="color: black; background-color: rgb(153, 255, 153);">RTP</b>/AVP 98
a=rtpmap:98 H263-1998/90000
a=fmtp:98 profile=0; level=40
b=TIAS:2048000
Where 7776 is the port you are streaming out to from above steps.
Save as say c:\testH263.sdp
Start <b style="color: black; background-color: rgb(255, 255, 102);">vlc</b> like this:
</pre>
<b style="color: black; background-color: rgb(255, 255, 102);">Vlc</b>
-vvv <a href="file://c:%5CtestH263.sdp">file://c:\testH263.sdp</a><br>
</blockquote>
</blockquote>

<pre>
Could we transcode the mp2 RTP stream using vlc or another program into a format openRTSP can record on the fly,
or directly use vlc to do the recording?
If so, what would be a good guess at parameters for the required sdp file?
Or is there a more direct path that escapes us?
