Camera Cape from Command Line

I have a BBW, with camera cape, but without DVI or LCD cape.

I’m running 2012-11-22 release.

Without a display, cheese doesn’t seem like an option for testing the camera.

Can someone recommend a command line method of capturing an image?

I’ve been trying with gstreamer, but I believe the cssp-camera driver must be missing some ioctls. I get “Could not get parameters on device /dev/video0”, and “system error: Inappropriate ioctl for device”.

Thanks,
Chris

Hi,
I am in a similar position. When booting up my BBW + DVI cape + Camera cape there is a conflict on pin P8.4 so only 1 device gets loaded.
Which one depends on the eeprom settings on each cape.
So I decided to dump the DVI cape and just use the camera cape.
Now I’m looking for command line utilities or a python library.
Did you manage to find anything?

If you are looking at Python, why not use the OpenCV bindings of
Python to capture images?

I think gstreamer and/or yavta should work. One trick is not to use the
first frame you get. It takes awhile for the agc of the sensor to work, so
you need to discard several frames at the beginning.
