Following a reboot there is now only one avcap device - I assume udev was
getting confused with the udevstart. So now avcctrl works and the capture
looks like it working, with the green light on the front flashing while
grabbing stuff from /dev/avcap0. But the video is completely black and no
sound. I'll try to find another cable to eliminate that, but it's strange
there's no video or sound.
Here's what I tried :-
# avcctrl -v -i -s COMPOSITE -f PAL -t MPEG2 -q BEST 0
lib init
AVCCONFInit running
retrieve int array
string =1,2
got int array rc=0
