I actually have two, an OV511 compatible, and the one above. The quickcam is
exceptionally good, visually, under linux. The C code to drive it 'cleaner'
than most I've had to endure. If ever I needed to point to some example code
of HOWTO develop a kernel driver, that one would be it. No question about
that. Not a comment about it's alpha quality, a comment about it's code
quality.
D Bandel fixed my problem for me. xawtv -noxv
the qce you refer to might be version 40b? from sourceforge. I downloaded it,
and separately used the CVS which is simply called quickcam. Both sources
compile clean and work very well on kernels >= 2.4.5 if you look at the
source, you'll notice a lot of #defines looking for that, or a later, kernel.
*serious* work is being done in usb folks. The days of modprobe are almost
over, Thank God.
Apart from my own stupidity with xawtv, I can report that this webcam is very
stable for me, being in continuous operation for days-at-a-time. Unlike most
streaming (ov511 eg), this 'alpha' product uses compression and the processor
load is consequently not noticeable (by me). What I have found however is
that applications like Sane are attrociously documented and never ever bare
much relationship to their man pages. Using Sane on these devices is a
serious excercise in futility. So bad in fact, that it looks like the usb
developers are rolling their own instead of continuing with that awful
product.
