[Live-devel] RTSP describe for RAW/UDP

[Gopinadhan Gautam]

I am in the process of building support for RTSP with
our streaming server and am using the VLC 0.8.1 with
the live.com RTSP library for testing the same. I
faced a problem which maybe someone can help me with.

- The streaming server is capable of only doing
RAW/UDP streaming. Therefore when VLC makes an RTSP
DESCRIBE request, I send an SDP response that says
that the supported transport is RAW/UDP. The SDP
response that I send back is:

sdp=v=0
o=NoSpacesAllowed 1 1 IN IP4 192.168.3.3
s=Test Stream
c=IN IP4 129.146.73.203
t=0 0
a=control:*
a=range:npt=0-
m=video 554 RAW/RAW/UDP 33

This has been derived from the internal translation
that the Live.com code does to a Kasenna MBase
DESCRIBE response for streaming MPEG-2 transport
streams over UDP.

After the SDP response is returned, the RTSP SETUP
command from the rtsp library however still requests
for a RTP/AVP stream. This is a bug I believe. Can
anyone confirm this?

I was able to get streaming to work however by
pretending to be Kasenna mediabase and sending the
session description in the proprietary Kasenna
format..

Thanks,
Gautam.
