Audio no Video

[ibizamale]

Hiya All,

We are outputting a video and audio stream to rtp/rtsp here is the code we are using

vlc -vvv udp://@234.5.90.131:4900 --sout '#transcode:rtp{dst=234.5.90.221,sdp=rtsp://10.10.10.101:8080/test.sdp}' --ttl 120

we know that udp://@234.5.90.131:4900 streams fine with audio and video.

When we run the command we get the following which is shown at the bottom

When we open the following address in vlc player

rtsp://10.10.10.101:8080/test.sdp

we get audio but no video.

any help would be greatly appreciated

regards





root@management:~# vlc -vvv udp://@234.5.90.131:4900 --sout '#transcode:rtp{dst=234.5.90.221,sdp=rtsp://10.10.10.101:8080/test.sdp}' --ttl 120
