Thanks. I downloaded the source for the kernel I'm running, applied the patch (it applied cleanly), so I built it and insmodded it, and ran motion -- this message motion: [1] VIDIOC_G_JPEGCOMP not supported but it should be (does your webcam driver support this ioctl?) no longer appears, but I still get motion: [1] Video device fatal error - Closing video device That might be bug in motion, but I'm not sure what else to use to test it. mplayer with -tv mjpeg says (inter alia) Selected driver: v4l2 name: Video 4 Linux 2 input author: Martin Olschewski <[email protected]> comment: first try, more to come ;-) v4l2: video fd: /dev/video0: 3 v4l2: your device driver does not support VIDIOC_G_STD ioctl, VIDIOC_G_PARM was used instead. Selected device: Live! Cam Optia Capabilites: video capture streaming supported norms: inputs: 0 = Camera 1; Current input: 0 Format MJPEG ( 0 bits, MJPEG): Unknown 0x47504a4d Format YUYV (16 bits, YUV 4:2:2 (YUYV)): Packed YUY2 Current format: YUYV v4l2: set format: YVU420 v4l2: ioctl set format failed: Invalid argument v4l2: set format: YUV420 v4l2: ioctl set format failed: Invalid argument v4l2: set format: UYVY v4l2: ioctl set format failed: Invalid argument v4l2: set format: YUYV v4l2: set input: 0 which doesn't look right -- it doesn't say "set format: MJPEG". xawtv just gives me a black window on my vncsession. luvcview and mjpeg-streamer work in MJPEG mode, but they did before the patch, so that's no test either. What would be the right way to test this?
