thank you again, paulo, for your off-list help. cam is now working nicely with xawtv, guvcview and skype. the colors slightly improved during day-light, when artificial light is used they still look bad though. i fiddled around with just about all v4l controls but couldn't really fix it. i'll run a comparison with windows driver when i have a chance.
for others interested: the fix was indeed the quirks mode. i had to set it like this: $ cat /etc/modprobe.d/uvcvideo.conf options uvcvideo trace=15 quirks=2 regards all, joe On Wed, Dec 9, 2009 at 11:53 PM, Paulo Assis <pj.as...@gmail.com> wrote: > You must reload the driver, > > rmmod uvcvideo > modprobe uvcvideo > > otherwise the quirks want have any effect. > > uvcvideo is now mantained in the mercurial repo at linuxtv, > installing v4l-dvb will also install uvcvideo, but if you want, just > follow the instructions on the wiki to compile, but use: > hg clone http://linuxtv.org/hg/~pinchartl/uvcvideo/ > so that you get the very latest (testing) uvc code. > In any case the quirks should be enough: > http://lists.berlios.de/pipermail/linux-uvc-devel/2009-October/005235.html > > Best regards, > Paulo > > 2009/12/9 Jozef Riha <jose1...@gmail.com>: >> setting quirks to 2 unfortunately did not help. gucview's 1.2.1 output below >> >> [j...@darkstar ~]$ LC_ALL=C guvcview --verbose >> guvcview 1.2.1 >> unexpected integer value (1) for snd_numsec >> Strings must be quoted >> video_device: /dev/video0 >> vid_sleep: 0 >> cap_meth: 1 >> resolution: 640 x 480 >> windowsize: 480 x 700 >> vert pane: 0 >> spin behavior: 0 >> mode: mjpg >> fps: 1/25 >> Display Fps: 0 >> bpp: 0 >> hwaccel: 1 >> avi_format: 0 >> sound: 1 >> sound Device: 0 >> sound samp rate: 0 >> sound Channels: 0 >> Sound delay: 0 nanosec >> Sound Format: 80 >> Sound bit Rate: 160 Kbps >> Pan Step: 2 degrees >> Tilt Step: 2 degrees >> Video Filter Flags: 0 >> image inc: 0 >> profile(default):/home/jose/default.gpfl >> starting portaudio... >> language catalog=> dir:/usr/share/locale type:C lang:C cat:guvcview.mo >> mjpg: setting format to 1196444237 >> capture method = 1 >> video device: /dev/video0 >> /dev/video0 - device 1 >> Init.
