Using VLC as RTSP server

Question

I'm trying to figure out how to use the server capabilities of VLC. More specifically, how to export an SDP file when RTP streaming. In chapter 4 in the section related to RTP Streaming examples for server and client are given:

vlc -vvv input_stream --sout '#rtp{dst=192.168.0.12,port=1234,sdp=rtsp://server.example.org:8080/test.sdp}'
vlc rtsp://server.example.org:8080/test.sdp

It's not very clear to me how to make it actually work. I have tried these two commands for server and client using two cmd instances:

vlc -I rc screen:// --sout=#rtp{dst=127.0.0.1,port=4444,sdp=rtsp://localhost:8080/test.sdp} 
vlc -I rc rtsp://localhost:8080/test.sdp

Invoking the second command causes the first one to crash. The second command shows the error message "could not connect to localhost:8080".

Answer 1

Your problem is that most likely the example you're looking at is for streaming a file and your example command is using the screen:// input. To make the screen:// device work you need to encode the video first. So try something like this:

vlc -I rc screen:// --sout=#transcode{vcodec=h264,vb=800,scale=0.25,fps=10}:rtp{dst=127.0.0.1,port=4444,sdp=rtsp://localhost:8080/test.sdp}
vlc -I rc rtsp://localhost:8080/test.sdp

Answer 2

You need to double quote the command

--sout="#transcode{vcodec=h264,vb=800,scale=0.25,fps=10}:rtp{dst=127.0.0.1,port=444‌​4,sdp=rtsp://localhost:8080/test.sdp}"
