capture s-video via ffmpeg (or: how to digitalise your old vhs-stuff)

I wanted to digitalise some old VHS-Videos.

The main thing is, that my /dev/video1 (TV-Card) has more than one inputs (regular TV-Cable input and S-Video). Challenge: how to tell the capture-program to grab s-video input instead of standard TV-Cable input?

After hours of searching with all possible programs on Linux, I finally ended up testing ffmpeg in the console.

ffmpeg -f alsa -ar 44100 -ac 1 -i plughw:0,2  -f video4linux2 -s sxga -r 25 -vc 2 -i /dev/video1 output.avi
