Re: Raspberry Pi OpenCV With Lifecam HD-3000

I have been unable to set the exposure via OpenCV calls on the pi, although the same code running in Windows or MacOSX works fine.

However, I AM able to set the exposure using v4l2-ctl:

$ v4l2-ctl --set-ctrl=exposure_auto=1
$ v4l2-ctl --set-ctrl=exposure_absolute=25

Running this before launching our OpenCV-based code seems to do the trick.

YMMV
