Nah its fixed :P
Its an acer ultrabook, the devices is conencted as a usb but its not like I
can plug it of unless I remove the LCD or something :P
I was jsut think that this might be driver related, which seems to be uvc:
% v4l2-dbg -D
Driver info:
Driver name : uvcvideo
Card type : 1.3M HD WebCam
Bus info : usb-/dev/usb-/dev/usb
Driver version: 2.6.38
Capabilities : 0x84200001
Video Capture
Streaming
Extended Pix Format
Device Capabilities
maybe its a bug in the driver that presenting something unexpected to
/dev/video, I was just tried with ffpmeg, recompiled with v4l support and
get the same error using -i /dev/video
[video4linux2,v4l2 @ 0x80ac6f000] ioctl(VIDIOC_STREAMON): Device not
configured
/dev/video0: Device not configured
