[Gumstix-users] Accessing Caspa Camera on Overo AirStorm

[Markus E. <mar...@df...>]

Dear all,

I am facing a problem with the connection of the camera. I have the
Overo AirStorm/Robovero Board.
I am using the Linaro Image which ships with ROS (the stock SD Card)

Kernel 3.5.0-2-linaro-omap

I have the camera attached.

ls -la /dev/video* shows me 7! video devices /dev/video0-video7.

I am connected to the overo with ssh -X

I am running the mplayer tv:// -tv driver=v4l2:device=/dev/videoX
command with X=0..6

With X=0,3,5 I get

#device /dev/video5 is not a video capture device.
#Opening as detected format "TV" failed.

On all other video devices I just an empty green window and the
following output
