Hi all,
I have Hyperion that works over RaspberryPi from 2014. First i used that to build ambilight effects when watching movies (with raspbmc). Later i decided to have the same effects with my TV. I used an USB capturer and mplayer2 for that. Later i moved only to Hyperion with v4l support 
And 3D !!!
But as i know there must be two different config files for Hyperion - one for internal grabber and one for v4l.
And because I was a bit lazy, i used "xbmc.callback" addon to trigger the switching between configs. Depending on "screensaver state"
<setting value="/home/pi/scripts/tv_on.sh" id="onScreensaverActivated_str.scr"/>
<setting value="/home/pi/scripts/hdmi_on.sh" id="onScreensaverDeactivated_str.scr"/>
My question - is there a simple way to do that with the new Hyperion?
Thanx in advance.
