[Spca50x-devs] Trouble with Intel Pro PC Web

["Tyler Oderkirk" <tyleroderkirk@xxxxxxxxx>]

Hello,

I'm having trouble getting my Intel Pro PC Camera (0733:0430) working.

I'm running Ubuntu 5.10 with kernel 2.6.12-10-386. I installed version
0.57.11 (20060402) of the spca5xx driver according to the GCC version
3.4 workaround at http://ubuntuforums.org/showthread.php?t=75284
(compiling spca5xx driver with GCC 4.0 instead of 3.4 caused my
machine to lock up)

Here's what shows up in /var/log/kern.log when I plug the camera in:
-------------snip-------------
/[...]/spca5xx.c: USB SPCA5XX camera found. Type Intel PC Camera Pro (SPCA505)
/[...]/spca5xx.c: [spca5xx_probe:8301] Camera type YYUV
/[...]/spca5xx.c: [spca50x_set_packet_size:1642] set real packet size: 0, alt=0
-------------/snip-------------

v4l(2?) seems to be running OK:
-------------snip-------------
$ lsmod | grep videodev
videodev                9344  1 spca5xx
-------------/snip-------------

The only webcam app that runs OK is gqcam. If I try to change any of
its settings (eg resolution, palette) I get lots of output like this:
-------------snip-------------
ioctl (VIDIOCSPICT): Invalid argument
ioctl (VIDIOCSWIN): Invalid argument
-------------/snip-------------

When I _don't_ try to change any settings, gqcam runs fine at 160x120
and only uses these ioctls, according to strace: FIONREAD, VIDIOCGCAP,
VIDIOCGWIN, and VIDIOCGPICT.

It seems to be the "set" ioctls (eg VIDIOCSWIN, and VIDIOCSPICT) that
are causing the trouble with motion, camorama, and the spca* tools.

When I run this code, I get an error on the VIDIOCSPICT:
-------------snip-------------
if (ioctl (vd->fd, VIDIOCGPICT, &vd->videopict) < 0)
 exit_fatal ("Couldnt get videopict params with VIDIOCGPICT");
if (ioctl (vd->fd, VIDIOCSPICT, &vd->videopict) < 0)
 exit_fatal ("Couldnt set videopict params with VIDIOCSPICT");
-------------/snip-------------

Here is the output I get from spcaserv:
