I'm trying to get my USB webcam (Logitech QuickCam Communicate STX) working on an Olimex SAM9-L9260 board (ARM). I have used Buildroot 2013.05 and have the system up and running. I want to take webcam snapshots and trying to use mplayer for this with this command:
mplayer tv:// -tv driver=v4l2:device=/dev/video0:width=320:height=240 -frames 1 -vo jpeg
This command works in Ubuntu, but not on my embedded board:
mplayer tv:// -tv driver=v4l2:device=/dev/video0:width=320:height=240 -frames 1 -vo jpeg
MPlayer 1.1-4.7.3 (C) 2000-2012 MPlayer Team
Playing tv://.
TV file format detected.
No such driver: v4l2
Exiting... (End of file)
Some start-up lines from the board:
Linux video capture interface: v2.00
uvcvideo: Unable to create debugfs directory
usbcore: registered new interface driver uvcvideo
USB Video Class driver (1.1.1)
gspca_main: v2.14.0 registered
usbcore: registered new interface driver gspca_zc3xx
When I connect the webcam to the board a LED in the camera goes on for a short while (same behaviour in Ubuntu) and the terminal prints:
usb 1-1: new full-speed USB device number 2 using at91_ohci
gspca_main: gspca_zc3xx-2.14.0 probing 046d:08ad
input: gspca_zc3xx as /devices/platform/at91_ohci/usb1/1-1/input/input0

Some V4L files in my board root folder:
./usr/lib/libv4lconvert.so
./usr/lib/libv4l
./usr/lib/libv4l/v4l1compat.so
./usr/lib/libv4l/v4l2convert.so
./usr/lib/libv4l1.so
./usr/lib/libv4l1.so.0
./usr/lib/libv4l2.so
./usr/lib/libv4l2.so.0
./usr/lib/libv4lconvert.so.0
What is missing? The camera is detected and I think that I got V4L (ver 1 or 2) support installed.
