The cam itself works (i.e. gives picture on the screen) with: $ pwcview -k Webcam set to: 320x240 (sif) at 5 fps but when I take snapshots it gives an error: $ pwcview -h -c 1 -o foo.jpg Webcam set to: 320x240 (sif) at 5 fps libv4l2: error turning on stream: Device not configured libv4l2: error reading: Invalid argument Error reading from webcam: Invalid argument $ This is with 11-CURRENT r285885 amd64 and ports r392920 (around July this year).
