the camera configuration strings in .yaml file for fawkes plugins seem to be ignored.

camera: v4l2:omni:device=/dev/video0:size=320x240:white_balance_temperature_auto=0:exposure_auto=1:exposure_absolute=305

Change History

I had the case today, that there was a config file called robotino.yaml (or something similar, i cant remember exactly right now, found it with a grep of this string) in which this weird omnivision string was set.
But it should be set in omnivision.yaml!

I don't know why this file suddenly existed but because of that there were two values for /hardware/robotino/omnivision/cam....

Just delete the strings for omnivision in this file and it should work

Hope this helps

And where did you get the string from? The documentation of V4L2Camera states:

/** Constructor.

 * Supported arguments:
 * *Required:
 * - device=DEV, device file, for example /dev/video0 (required)
 * *Optional:

 *    READ: read()
 *    MMAP: memory mapping
 *    UPTR: user pointer
 * - format=FOURCC, preferred format
 * - size=WIDTHxHEIGHT, preferred image size

Most of the parameters you mention are not supported.
