What the application does with the data is up to you ... v4l2 has format IDs for both big and little endian versions of the RGB formats. v4l1 uses little endian, so you have to swap stuff if you need native byte ordering. For v4l1-overlay bttv has a dirty hack to enable byteswapping, which helps making the overlay work in 15/16 bpp on BE machines (my iMac for example). Gerd -- sigfault
