I just noticed that mpv somehow managed to work with Vulkan without shaderc!
Here is my configuration in $HOME/.config/mpv/config
[gpu-vulkan]
vo=gpu-next
gpu-api=vulkan
hwdec=vaapi
gpu-context=waylandvk
[default]
profile=gpu-vulkan
Here is some of what I see when running with --msg-level=all=debug
[vo/gpu-next/vulkan] Initializing GPU context 'waylandvk'

[vo/gpu-next/libplacebo] Spent 2.067 ms creating vulkan instance

[vo/gpu-next/libplacebo] Spent 0.802 ms translating SPIR-V

[vo/gpu-next/libplacebo] Pass statistics: size 0, SPIR-V: vert 0 frag 0

...
So it clearly somehow manages to compile shaders to SPIR-V without shaderc!
May be libplacebo has some built in compiler?
Just wanted to share if anyone was waiting to start using Vulkan with your
mpv.
