[bite_your_idols]

@bite_your_idols doesn't really mean much to me. Did anyone establish which build introduced the dark behaviour?

The last build with video grabber working ok is: 0219
The first build with dark video grabber image is: 0220

This build hHighlight is "New 4.10.0 kernel" so I guess hyperion team developers are right when talking about kernel update issue... They say that it can adjusted using som v4l-utils and v4l-ctl but I really don't know what are they talking about...

I hope this can help...
