Hello,

I have Genius Facecam 1000 (UVC, MJPEG capable) webcam and want to stream video with mjpg-streamer from Olimex L9260 board. It worked fine with Facecam 1320, but only in YUV mode (and low resolution), so jpeg compression was on ARM and it generated about 20% CPU load. So I switched to Facecam 1000 which is MJPEG enabled. It works fine on my PC (tested with mjpg-streamer, luvcview), but it doesn't work on ARM. I get this error:

libv4l2: error turning on stream: Input/output error

It fails on this:

ret = xioctl(vd->fd, VIDIOC_STREAMON, &type);

System on kit: kernel 2.6.33.7, uClibc 0.9.32-rc3. Mjpg-streamer is svn revision 144, libv4l 0.8.3.

Thanks for any advice.

Best regards,
Zdenek Materna
