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 <jose1711@xxxxxxxxx>: > setting quirks to 2 unfortunately did not help. gucview's 1.2.1 output below > > [jose@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.
