I'm running 3.1 Sarge from the orignal install discs when it was released and have done no updates as the machine is not connected to the net.
I'm trying to use ffmpeg to capture video from my WinTV card by using:

ffmpeg -vd /dev/video0 -f avi -vcodec mpeg4 -vtag xvid video.avi

However when I run this I get the following error message:

'could not find video grab device'

I've got xawtv installed which is using /dev/video0 and it works fine and I've used it to set the channel I want to capture from.

How can xawtv access /dev/video0 and ffmpeg cannot? I've tried changing the permissions and ownership for /dev/video0 and this hasn't made a difference.

I know it's possible having achieved the capture with ffmpeg using the dyne:bolic live cd but want to set it up under Debian.

Any help would be greatly appreciated,

Harry.
