Public bug reported:
Please rebuild the package and to the problem!
This happens because your mpv is compiled without support for
libshaderc, which is the only SPIR-V backend that mpv supports for now
(apart from the deprecated nvidia-only VK_NV_glsl_shader which we will
be dropping support for eventually). To solve the issue you will need to
install libshaderc and make sure mpv is built against it.
Note: It wouldn't be too difficult to support using glslang directly
instead of shaderc. I have already written a C wrapper for glslang for
this purpose for a different project; if you want to try merging it to
mpv I could offer some pointers. That said, using shaderc is still
preferred to glslang since it means you (i.e. we) get better
diagnostics.
