[Live-devel] openrtsp + H261?

[peter green]

All,

I have a Polycom VSX7000e video teleconferencing thing that I'm trying to
use to simultaneously broadcast and archive a copy of video.  I send the
video to a Darwin Streaming Server and broadcast from there; the streams
work great.

I tried using openRTSP to grab the stream and save to a file, but received
an error:

  # /root/live/testProgs/openRTSP -e 10 -w 352 -h 288 -q rtsp://10.9.0.1/videostream.sdp > stream.mov
  Warning: The -q, -4 or -i option was used, but not -f.  Assuming a video
  frame rate of 15 frames-per-second
  Opened URL "rtsp://10.9.0.1/videostream.sdp", returning a SDP description:

  Warning: We don't implement a QuickTime Video Media Data Type for the

  separate, codec-specific editing pass will be needed before this track can
  be played.
  Started playing session
  Receiving streamed data (for up to 10.000000 seconds)...

The resulting stream.mov file is garbage, apparently since video/H261 isn't
supported by openRTSP.  My question(s): is it possible to do what I'm trying
to do with the live555 tools?  If so, how?  If not, what can I use to
accomplish my goal?

I've also looked at VLC (doesn't support DSS) and mp4live (GUI crashes,
command-line mp4live simply refuses to save to file).  Nothing out there
seems to adequately describe how to do what I want, so I'm hoping someone
here has a brilliant idea. :-)

Thanks!
