VideoLAN device addressing in VLC

Question

How do I get the VideoLAN device information that corresponds with /dev/video, and /dev/video1 for vlc targetting?

This command kind of does what I want:

vlc v4l2:// -vvv input_stream --sout='#duplicate{dst=display, dst="transcode{venc=x264{keyint=60,idrint=2},vcodec=h264,vb=300,acodec=mp4a,ab=32,channels=2,samplerate=44100}:rtp{dst=127.0.0.1,port=1234,sdp=file:///home/ecarroll/vlc.sdp}"}

However I want to target my second webcam, not the first one. How do I do the v4l2:// for my second webcam?

Answer 1

I'm not sure if this is the only way to do it but

`v4l2://` `+` `/dev/video1`

= `v4l2:///dev/video1`
