[pwc] Motion and PWC driver

[Balazs Bezeczky <>]

Hi there,

I'm trying to get my new system running (Debian Sarge) and tried to get
motion and my old Phillips 680K cam to run on a standard debian 2.4 kernel.
It worked, except I got green images and I was told "pwc Video mode
 fps is only supported with the decompressor module (pwcx)." -
whatever that means (I thought pwcx is dead?)

Then I thought, I should upgrade my kernel, because I saw the PWC
section in the motion Wiki.
I upgraded to debian-2.6.8-3-k7 and when I try to run motion I get this:
[0] Processing thread 0 - config file /etc/motion/motion.conf
[0] Thread is from /etc/motion/motion.conf
[1] Thread started
[0] motion-httpd/3.2.6 running, accepting connections
[0] motion-httpd: waiting for data on port TCP 8080
[1] Failed with YUV420P, trying YUV422 palette: No such file or directory
[1] Failed with YUV422, trying RGB24 palette: Invalid argument
[1] Failed with RGB24, trying GREYSCALE palette: Invalid argument
[1] Failed with all supported palettes - giving up: Invalid argument
[1] Capture error calling vid_start
[1] Thread finishing...

so I thought, I`ll get the pwc sources and install them without
recompiling the kernel. No matter which version (10.0.10 or 10.0.11) I
try, I get this:

make -C /lib/modules/2.6.8-3-k7/build SUBDIRS=/usr/src/pwc-10.0.10 modules

I checked pwc-ioctl.h line 309 and its neightborhood but I cannot
discover anything strange there.

Can somebody please help me with this getting my can to work correctly?

thanks in advance,
Balazs
