Attempting to try out your patches, but it's failing with the following: usb-uvc: Init called usb-uvc: Trying to open /dev/video0 .usb-uvc: Device opened correctly. usb-uvc: Querying capabilities. usb-uvc: Device driver: uvcvideo usb-uvc: Device name: Laptop_Integrated_Webcam_0.3M usb-uvc: Device bus: usb-0000:00:1a.7-6 usb-uvc: Driver version: 0.1.0 usb-uvc: Device capabilities: 0x04000001 usb-uvc: Enumerating video inputs. usb-uvc: Setting video input to index 0 usb-uvc: Video input correctly set. usb-uvc: Trying to set 320x240 MJPEG. qemu-system-x86_64: -device usb-uvc-webcam,device=/dev/video0: Invalid format. Using ekiga for example I know that 320x240 is ok. I know very little about the v4l (or video in general). Can you provide some pointers? 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 David
