## Failed to Load Shaders

I tried to setup [Anime4K](https://github.com/bloc97/Anime4K) on my MacBook Pro with M1 Max according to the [official guide](https://github.com/bloc97/Anime4K/blob/master/GLSL_Instructions.md), but it didn't work.

By checking the [log](https://mpv.io/manual/stable/#options-v), I found that the file path to shaders is not correct. [mpv](https://mpv.io/manual/stable/) didn't parse the path string properly.

```log
[file] Cannot open file '/Users/<USERNAME>/.config/mpv/shaders/Anime4K_Clamp_Highlights.glsl;~~/shaders/Anime4K_Restore_CNN_M.glsl;~~/shaders/Anime4K_Upscale_CNN_x2_M.glsl;~~/shaders/Anime4K_AutoDownscalePre_x2.glsl;~~/shaders/Anime4K_AutoDownscalePre_x4.glsl;~~/shaders/Anime4K_Upscale_CNN_x2_S.glsl': No such file or directory
[stream] Failed to open /Users/<USERNAME>/.config/mpv/shaders/Anime4K_Clamp_Highlights.glsl;~~/shaders/Anime4K_Restore_CNN_M.glsl;~~/shaders/Anime4K_Upscale_CNN_x2_M.glsl;~~/shaders/Anime4K_AutoDownscalePre_x2.glsl;~~/shaders/Anime4K_AutoDownscalePre_x4.glsl;~~/shaders/Anime4K_Upscale_CNN_x2_S.glsl.
```

## Solution

So I had to put the shader configurations inside [profiles](https://mpv.io/manual/stable/#profiles), and set shortcut to load the profile instead of to load shader via [change-list](https://mpv.io/manual/stable/#command-interface-change-list) as the official guide instructed.

- mpv.conf

```conf
# #Profile to load Anime4K shaders
[Anime4K]
glsl-shaders-append="~~/shaders/Anime4K_Clamp_Highlights.glsl"
glsl-shaders-append="~~/shaders/Anime4K_Restore_CNN_M.glsl"
glsl-shaders-append="~~/shaders/Anime4K_Upscale_CNN_x2_M.glsl"
glsl-shaders-append="~~/shaders/Anime4K_Restore_CNN_S.glsl"
glsl-shaders-append="~~/shaders/Anime4K_AutoDownscalePre_x2.glsl"
glsl-shaders-append="~~/shaders/Anime4K_AutoDownscalePre_x4.glsl"
glsl-shaders-append="~~/shaders/Anime4K_Upscale_CNN_x2_S.glsl"
```

- input.conf

```conf
# Clear loaded glsl-shaders; apply Anime4K shader profile
CTRL+1 no-osd change-list glsl-shaders clr ""; apply-profile "Anime4K"; show-text "Profile: Anime4K"

CTRL+` no-osd change-list glsl-shaders clr ""; show-text "GLSL shaders cleared"
```

## HW+ and Performance

To turn on hardware acceleration, I had to add the following to `mpv.conf`:

```conf
# #The default profile which sets some recommended settings
profile=gpu-hq 

# #The called API
# #Use "opengl" if you have compatibility issues.For displaying HDR content (not HDR -> SDR) "d3d11" is recommended (Windows only). 
gpu-api=vulkan

# #Hardware decoding for whatever your CPU/GPU supports (e.g. 8bit h264 / 10bit h265)
# #Only should be used when your CPU/GPU are very old, else avoid using it
# #Use "auto-copy-safe" for the safest result in trade of better performance
# #You can manually try "d3d11va" / "dxva2-copy" on Windows, "vaapi" / "vaapi-copy" on Linux or "nvdec" / "nvdec-copy" with an Nvidia GPUs
hwdec=auto-safe
```

`Anime4K: Mode A+A (Fast)` is tested to be the best mode for my MacBook Pro with M1 Max. 

Though it is working, I presume Anime4K is not optimized for Apple Silicon yet.
