Thanks for the report. I'll update the supported devices list on the website. Could you please tell me the commercial name of the webcam, or in which laptop model it can be found ? > What doesn't look right is this: > > $ cat /dev/video0 > cat: /dev/video0: No such device > > although that device node works for video software. That's normal. The uvcvideo driver doesn't support the read() method. > GO: > In my tests the camera worked with ffmpeg (SVN-r20396), and thus: mplayer > (SVN-r29799-4.3) and kdenlive.

Your luvcview version defaults to MJPEG and doesn't fall back to YUV automatically. Your camera supports YUV only, so the default won't work. luvcview -f yuv should work. > Attached: output of lsusb -v, xawtv, mplayer, luvcview, etc. Thanks. > PS: I purchased the camera from www.conrad.at, and I find their technical > specification quite remarkable: > > "Resolution Photo: 640 x 480 Pixel (interpolated: 3200 x 2400 Pixel)" > > http://shop.conrad.at/ce/de/product/971972/CONRADWEBCAMMITSCHWANENHALS/132 > 0051 > > Oh, right.
