I am using SM Player on Windows.

Please go to https://github.com/boned101/MPV-Custom-Shaders/tree/main. It has adaptive-sharpen.glsl and SSimSuperRes.glsl.

Also please go to https://github.com/butterw/bShaders. It has grain.glsl and contrast.10.hk.

I downloaded those 4 shaders and I put them in C:\Users\xyz\AppData\Roaming\mpv\shaders.

I was able to make adaptive-sharpen.glsl work in SM Player by going to preferences --> advanced --> mpv and then I put the below line under options:

--glsl-shaders="C:\Users\xyz\AppData\Roaming\mpv\shaders\ adaptive-sharpen.glsl"

I confirmed that it worked by pressing shift and I twice and it said adaptive-sharpen in the info screen. Next I tried:

--glsl-shaders="C:\Users\xyz\AppData\Roaming\mpv\shaders\ SSimSuperRes.glsl"

--glsl-shaders="C:\Users\xyz\AppData\Roaming\mpv\shaders\ contrast.10.hk"

--glsl-shaders="C:\Users\xyz\AppData\Roaming\mpv\shaders\ grain.glsl"

but nothing happened and those 3 shaders didn't show when I pressed shift and I twice. Why is that?

Also I only know how to use one shader at a time. What do I type under options so I use more than one shader at the same time? I need to use a sharpening shader, a grain shader and a contrast shader at the same time.
