Frei-Chen Edge Detection (in Luma)
original source code (freichen.frag): http://rastergrid.com/blog/2011/01/frei-chen-edge-detector/
glsl-shader adapted to mpv .hook by butterw

best results as a LUMA hook but can also work on MAIN or OUTPUT, can be combined with NoChroma.hook.

bTimeEffect_DePixelate (square pixels) 
by butterw
control a video pixel shader effect vs time.  

tested in mpc-hc v1.9.3: 
- Opening the player by double clicking a video starts the clock
- Short effect/glitch repeats every 10 seconds by default (T).
- Note that Loading another video or Pause/Stop does not reset the clock !

/* bSide.hlsl by butterw v1.0 (ZoneShader_mpc)

- this directX pixel shader shows how to apply effects to an xy-zone of the video (half the screen, or a box)
applications:
	- half the screen: Side by side effect comparisons.
