/dev/video0 device or resource busy

Hi Men,

Thank you for read this.

I have Angstrom Linux running on BeagleBone Blacka and an USB webcam.

When I run this command: mplayer -fs mplayer tv:// -tv device=/dev/video0:driver=v4l2:width=320:height=240 -fps 25 -fs
I will get message “v4l2: unable to open ‘/dev/video0’: Device or resource busy

When I type lsmod, I get this result:

sh-4.2# lsmod

I’ve already tried Cheese Webcam Booth but it doesn’t work, it crashes after loading something.

Please help me.
