Reflecting stream with VLC via DSS?



Hello All,

Based on those notes:
http://lists.apple.com/archives/Streaming-server-dev/2007/Jan/msg00029.html
"Interoperation in between DSS and VideoLAN"

I'm trying to reflect stream captured by VLC thru DSS5.5.5 on Solaris10
(which includes your patch) like this:

vlc -vvv --http-reconnect --noaudio --loop
http://192.168.73.33/axis-cgi/mjpg/video.cgi?resolution=640x480 --sout
#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128,deinterlace}:duplicate{dst=
display,dst=rtp{dst=192.168.40.6,port-audio=20000,port-video=20002,ttl=127,
sdp=sap,sdp=file://C:\tmp\webcam.sdp}}

Now copying webcam.sdp to /usr/local/movies let me see the stream with
QTPlayer at rtsp://192.168.40.6/webcam.sdp


Now it says that there is a way to stream from VLC to DSS so "In that way,
the SDP metadata is transferred to DSS during the RTSP negotiation phase,
and no manual copy of the SDP file is needed..."

So, I've read this howto
http://soundscreen.com/streaming/webcast/howto_webcast.html

And did:

bash-3.00# cat /etc/streaming/qtusers
realm Streaming Server
dssadmin:RtqrqAI/WwmZw:45a740868cc34a485e8b9f16146aa8be

bash-3.00# /usr/local/bin/qtpasswd bcast
Adding userName bcast
New password:
Re-type new password:
bash-3.00# cat /etc/streaming/qtusers
realm Streaming Server
dssadmin:RtqrqAI/WwmZw:45a740868cc34a485e8b9f16146aa8be
bcast:/4mMKgQy6Gv1Y:532202bad30266632ab28bd8ebb0b7c5


Created /usr/local/movies/qtaccess:
<Limit WRITE>
require user bcast
</Limit>
require any-user

Now trying to stream thru VLC to DSS like this:

vlc -vvv --http-reconnect --noaudio --loop
http://192.168.73.33/axis-cgi/mjpg/video.cgi?resolution=640x480 --sout
#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128,deinterlace}:duplicate{dst=
display,dst=rtp{dst=192.168.40.6,port-audio=20000,port-video=20002,ttl=127,u
ser=bcast,pwd=secret, sdp=file:///usr/local/movies/webcam.sdp}}

I've got "stream_out_rtp error: cannot open file
'/usr/local/movies/webcam.sdp' (No such file or directory)" at VLC messages.

No webcam.sdp is created automatically, therefore no streaming via DSS is
performed.

How can I make it work automatically?
Any ideas?


Best Regards,
Leon Kolchinsky
