MJPEG devices don't include Huffman tables in the JPEG data. Resulting images can't be opened by most image viewers. This is normal and there's nothing to worry about. You can convert MJPEG data to JPEG using the attached python script. > lsusb output for webcam mode >> [snip] > The story for dv-mode is a bit different though, no output at all (not > so strange). > > Bus 001 Device 020: ID 04da:231a Panasonic (Matsushita) > > lsusb output for dv-mode >> [snip] Most applications don't support DV data. You might have more success with MPlayer which should be able to display the DV stream. Best regards, Laurent Pinchart
