[VLC - Darwin Streaming Server]Problem with multiple stream

[tigershark]

Hi all,
I have seen a couple of thread about this problem, but i could not a find a clear working solution.
My current system is configured in this way:

- a MS windows PC
- a USB webcam
- a network camera
- VLC
- Darwin Streaming Server

I can stream succesfully each of my two cameras to Darwin Streaming Server sending the generated sdp file to the darwin's movies directory.
But if I send the two streams simoultaneously to darwin, the second one get crippled out because the RTP video port is the same.
So i thought: "Ok, I need only to change the rtp-port-video parameter specifying a different port for each of the streams".
But I can't make it work.

The VLC command line parameters that I use are these:

1) vlc dshow:// --dshow-vdev="TRUST 120 SPACEC@M" --dshow-adev="none" --dshow-size="" --sout "#transcode:rtp" --sout-transcode-vcodec="mp4v" --sout-transcode-vb="96" --sout-transcode-scale="1" --sout-rtp-dst="192.168.104.139" --sout-rtp-port-video="5001" --sout-rtp-ttl="127" --sout-rtp-sdp="file://C:\Program Files\Darwin Streaming Server\Movies\1.sdp"

2)vlc http://192.168.104.103:8000/image?speed=10 --sout "#transcode:rtp" --sout-transcode-vcodec="mp4v" --sout-transcode-vb="192" --sout-transcode-scale="1" --sout-rtp-dst="192.168.104.139" --sout-rtp-port-video="5002" --sout-rtp-ttl="127" --sout-rtp-sdp="file://C:\Program Files\Darwin Streaming Server\Movies\2.sdp"

But whenever I add the --sout-rtp-port-video option i cannot access any of the streams, receiving on the client side this error:

main debug: `rtsp://127.0.0.1/1.sdp' successfully opened
live555 warning: no data received in 10s. Switching to TCP

The instance of VLC sending the video produces this log:

Have you got any idea to make VLC succesfully work with Darwin Streaming Server using an rtp-port-video different form the default port?

Hi,

I supose you would have resolved your problem time ago. Anyway, if you see the sdp generated in the vlc log messages, you would see, in both instaces of vlc for each cam, if rtp video ports are correctly established. I suggest you try followings options instead of --sout-rtp-port-video:
cam1: --sout-rtp-port=5002 --sout-rtp-port-video=5000
cam1: --sout-rtp-port=6002 --sout-rtp-port-video=6000
(choosing any direfents even ports for each cam)
