Due to burn-in problems on OLED TVs i decided to script a screensaver for mpv. After 15 seconds when paused it just fades-in a black screen.
Time after screensaver is shown in seconds (Default: 10s).
Colour of the screensaver in ASS hex BBGGRR (Default: "000000").
Instead of using one colour, use a rainbow colour transition (Default: false).
How many colour steps per period (Default: 1).
Time between redraws of the rainbow in seconds (Default: 0.03).
How many steps for the fade-in of the screensaver (Default: 12).
The Luminace of the rainbow colours (Default: 255).
