【Ubuntu 10.10】mjpg-streamer：Init v4L2 failed

系统：Ubuntu 10.10启动： ./start.sh错误内容:root@www.linuxidc.com:~/mjpg-streamer/mjpg-streamer-experimental# ./start.sh
MJPG Streamer Version: svn rev: 3:160
i: Using V4L2 device.: /dev/video0
i: Desired Resolution: 640 x 480
i: Frames Per Second.: -1
i: Format............: JPEG
Unable to set format: 1196444237 res: 640x480
Init v4L2 failed ！！ exit fatal
i: init_VideoIn failed错误原因：市面上大部分摄像头都是支持YUV的，而不是JPEG的。mjpg-stream支持JPEG和YUV两种格式。[www.linuxidc.com@linuxidc mjpg-streamer]$ cd mjpg-streamer-experimental/plugins/input_uvc/[www.linuxidc.com@linuxidc input_uvc]$ vim input_uvc.cint input_init（input_parameter *param, int id）
{
    char *dev = "/dev/video0", *s;
    int width = 640, height = 480, fps = -1, format = V4L2_PIX_FMT_MJPEG, i;

    /* initialize the mutes variable */
    if（pthread_mutex_init（&cams[id].controls_mutex, NULL）！= 0） {
        IPRINT（"could not initialize mutex variable "）;
        exit（EXIT_FAILURE）;
    }
......................format = V4L2_PIX_FMT_YUYV以上就设置了默认的图像格式，重新把模块编译，之后就成功了！
