sending usb stream

Postby xha1e » 09 Mar 2024 00:21

Is there anything wrong with my vlc commands for sending and recieving a stream? I would like to send a usb camera stream from one Pi4 to another and view it on a screen. I was able to successfully encoder and decode the stream on teh same device (view the usb camera on the hdmi output of the same device), but cant seem to send it over the network. The pi4's are on the same network and can ping each other.

Encoder command to start stream on pi4-#1 with webcam attached:

Code: Select all

vlc -vvv v4l2:///dev/video0 --sout '#transcode{vcodec=h264,venc=x264{vf=scale=1},acodec=none}:rtp{dst=0.0.0.0,port=1234,sdp=rtsp://localhost:8080/test.sdp}'

Decoder command to view stream on pi4-#2 with hdmi screen attached:

Code: Select all

vlc rtsp://cm4-e45f01b6fd99.local:8080/test.sdp
Result:
vlc rtsp://cm4-e45f01b6fd99.local:8080/test.sdp
