Hi,
libv4l is already packaged by lenny but doing
LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so xawtv
results in either a plain green screen or a mostly green screen with some
picture visible behind it. IIRC this is due to a bug in older versions of
xawtv. I didn't try vlc as it wanted to install too many dependencies but I
did try cheese which also wouldn't work.
I did find I could capture single frames with
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so vgrabbj -d /dev/video0 >grab.jpg
or
LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so fswebcam --save grab2.jpg
which suggests that the packaged libv4l is fine and it is just the apps that
are an issue.
