SDP File Generation

Postby diptendu » 02 Sep 2005 08:43

The Streaming How To mentions the use of SDP files for RTP streaming. How does one use VLC to create a SDP file? I wish to stream live from a web cam using RTP so that the client can simply use

vlc rtsp://domain/file.sdp

The question is how to generate the correct SDP file for the given configuration.

Regards,

Hello,

If you use the "rtp" stream output module, the SDP will be generated automatically :

vlc input_stream --sout '#transcode{transcode_options}:rtp{sdp=rtsp://0.0.0.0:554/test.sdp}'

or

vlc input_stream --sout '#rtp{sdp=rtsp://0.0.0.0:554/test.sdp}'
if transcode is not needed

and on the client

vlc rtsp://server/test.sdp

Hello,

I tried

vlc AA.Mp3 :sout=#rtp{sdp=rtsp:// 192.168.0.8:5000/rtp.sdp}

and the file is playing on the server side but on the client side I am
getting

livedotcom error describeURL failed {connect[] failed unknown error}
no access-demux module matching "rtsp" could be loaded
.......

Hi,

I too was trying to get live capture from a usb webcam and generate an sdp file out of it. Ideally I would like to send this converted stream to a streaming server which would eventually do the streaming.

FOr the command line options given below, what should be the "input stream " switch when a webcam stream is to be delivered.

It'll be great if anyone could shed some light on this.
