As for now only cameras that allow MJPEG format will work. Check your camera specifications (lsusb -v works if your real camera is UVC, check driver's source otherwise). Cameras with RAW frames (YUYV and NV12 formats) do not work, yet. I'm on it. > > Also, I tried a PWC camera which is not a V4L2_INPUT_TYPE_CAMERA and > noticed that video_input_index is used uninitialized in usb_uvc_initfn It's a webcam? Could you give me more information? Manufacturer, model, linux's module name. All webcams SHOULD (and MUST) implement V4L2_INPUT_TYPE_CAMERA. Not the same for video cameras or capture devices (PAL/NTSC, DVB/ATSC). Regards, Natalia Portillo
