Hyperion on Raspberry Pi does its grabbing using dispmanx / frame grabber - which means that it is running independently of Kodi.
Is there a way (apart from me stopping/starting Hyperion) to send light updates only when a video is playing?
I understand that the Kodi add-on does this by sending the light updates to Hyperion but that does not help on RPi.
If there was a JSON function in Hyperion to Suspend/Resume Hyperion updates then this could be a way to do it - then Kodi add-on could send that (and skip sending light details on RPi).
