Hi,

i agree. i don't like threads, but it seems it's th only way here, as v4l
ioctl blocks and you can't delay more than 1 frames...

> - fixed colorspace stuff - RGB?? and YUY2 modes now work as expected
> - native ALSA audio capture (optional - just #define ALSA_CAPTURE)

sounds cool :)

could others - with v4l card, i don't have any - test it with various
configuration/hardware and report results?

you should post it to -users list too, for a big test-base.
if it's reported as ok, or at least better than current one, i'm not against
commiting it to cvs. 

please someone also verify if it doesn't break the bsd tv support, it seems
to be ok, but to be sure...
