DV from webcams

DVswitch is a neat piece of software, but it only works with DV streams. If you want to use something else (like, say, a webcam), you'll need to do something 'special':

wouter@celtic:~$ mkfifo dvsource-fifo
wouter@celtic:~$ ffmpeg -f video4linux2 -r 25 -s vga -i /dev/video0 -target pal-dv - > dvsource-fifo
wouter@celtic:~$ dvsource-file dvsource-fifo

And there you are, a DV stream from my webcam. Not that this is very useful, probably—but who cares, right?
