The V4L2 shuts down properly if the grabber don´t get a signal. Sadly hdmi splitter output often a signal (eg blue)
Might there a way to "detect" (like blackborder processing) this as a shutdown condition to prevent blue leds in general. And open the possibility for automatically applied effects and static color as a idle state
