KVDR has a number of different parameters including -x force xv-mode on startup and disable overlay-mod -d dont switch modeline during xv with kernel 2.6.35 I run KVDR with -x as I have an NVIDIA graphics. Running on 2.6.38 KVDR -x doesn't produce any log. The display appears and immediately disappears although there is a process running. With KVDR -d I get a display window but no picture but the attached log is produced. I hope this helps Mike libv4l2: open: 4 request == VIDIOC_G_FMT pixelformat: BGR3 384x288 field: 0 bytesperline: 0 imagesize331776 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 0, description: RGB-8 (3-3-2) result == 0 request == VIDIOC_TRY_FMT pixelformat: RGB1 48x32 field: 3 bytesperline: 48 imagesize1536 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: RGB1 768x288 field: 3 bytesperline: 768 imagesize221184 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 1, description: RGB-16 (5/B-6/G-5/R) result == 0 request == VIDIOC_TRY_FMT pixelformat: RGBP 48x32 field: 3 bytesperline: 768 imagesize24576 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: RGBP 768x288 field: 3 bytesperline: 1536 imagesize442368 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 2, description: RGB-24 (B-G-R) result == 0 request == VIDIOC_TRY_FMT pixelformat: BGR3 48x32 field: 3 bytesperline: 1536 imagesize49152 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: BGR3 768x288 field: 3 bytesperline: 2304 imagesize663552 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 3, description: RGB-32 (B-G-R) result == 0 request == VIDIOC_TRY_FMT pixelformat: BGR4 48x32 field: 3 bytesperline: 2304 imagesize73728 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: BGR4 768x288 field: 3 bytesperline: 3072 imagesize884736 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 4, description: RGB-32 (R-G-B) result == 0 request == VIDIOC_TRY_FMT pixelformat: RGB4 48x32 field: 3 bytesperline: 3072 imagesize98304 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: RGB4 768x288 field: 3 bytesperline: 3072 imagesize884736 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 5, description: Greyscale-8 result == 0 request == VIDIOC_TRY_FMT pixelformat: GREY 48x32 field: 3 bytesperline: 3072 imagesize98304 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: GREY 768x288 field: 3 bytesperline: 3072 imagesize884736 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 6, description: YUV 4:2:2 planar (Y-Cb-Cr) result == 0 request == VIDIOC_TRY_FMT pixelformat: 422P 48x32 field: 3 bytesperline: 3072 imagesize98304 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: 422P 768x288 field: 3 bytesperline: 3072 imagesize884736 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 7, description: YVU 4:2:0 planar (Y-Cb-Cr) result == 0 request == VIDIOC_TRY_FMT pixelformat: YV12 48x32 field: 3 bytesperline: 3072 imagesize98304 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: YV12 768x288 field: 3 bytesperline: 3072 imagesize884736 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 8, description: YUV 4:2:0 planar (Y-Cb-Cr) result == 0 request == VIDIOC_TRY_FMT pixelformat: YU12 48x32 field: 3 bytesperline: 3072 imagesize98304 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: YU12 768x288 field: 3 bytesperline: 3072 imagesize884736 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 9, description: YUV 4:2:2 (U-Y-V-Y) result == 0 request == VIDIOC_TRY_FMT pixelformat: UYVY 48x32 field: 3 bytesperline: 3072 imagesize98304 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: UYVY 768x288 field: 3 bytesperline: 3072 imagesize884736 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 10, description: RGB3 result == 0 request == VIDIOC_TRY_FMT pixelformat: RGB3 48x32 field: 3 bytesperline: 144 imagesize4608 colorspace: 0, priv: 0 result == 0 request == VIDIOC_TRY_FMT pixelformat: RGB3 768x288 field: 3 bytesperline: 2304 imagesize663552 colorspace: 0, priv: 0 result == 0 request == VIDIOC_ENUM_FMT index: 11, description: result == -1 (Invalid argument) request == VIDIOC_ENUMINPUT result == 0 request == VIDIOC_ENUMSTD result == 0 libv4l1: open: 4 request == VIDIOC_QUERYCAP result == 0 request == VIDIOC_G_FBUF result == 0 request == VIDIOC_S_FBUF result == 0 libv4l2: close: 4 libv4l1: close: 4 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
