I didn't mention that because the shop sells it under its own brand as just "Conrad Webcam mit Schwanenhals" (engl. "Webcam with Gooseneck") and an article number (97 19 72). There's no producer mentioned or a 'proper' article name. Just see the link that I posted -- that's all there is, and nothing more on the box: http://shop.conrad.at/ce/de/product/971972/CONRADWEBCAMMITSCHWANENHALS/1320051 This cam is separate, not built into a laptop. Interesting design: http://shop.conrad.at/medias/global/ce/9000_9999/9700/9710/9719/971972_AB_00_FB.EPS_400.jpg I assume(d) that it's produced by some "no-name" company (no, I don't mean eMPIA), and that every seller just slaps its brand on it. Then it would probably also be available under different, possibly better known names. > > $ 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. Well, but the answer is still wrong and misleading. Wouldn't it be better to just return no data? IOW: the device *does* exist, but doesn't return anything that way. > Your luvcview version defaults to MJPEG and doesn't fall back to YUV > automatically.

(BTW: I had also tried the latest version from SVN (r19), but that doesn't compile due to missing header files.) > > Oh, right.

This Qt4/GPL3 one, for example: http://imageenlarger.sourceforge.net/ $ svn co https://imageenlarger.svn.sourceforge.net/svnroot/imageenlarger/trunk imageenlarger $ qmake && make Worth trying out if you are into such things! :-) m. _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
