Details

Description:

The built package lacks Vulkan support, which was introduced with 0.28.

Additional info:
* package version(s): 0.28.2-1

"vulkan-icd-loader" is needed for libvulkan and the autodetection during configuration and "vulkan-headers" for building, so I suggest adding those two as makedepends and maybe "vulkan-driver" to optdepends.


Steps to reproduce:
run mpv with --gpu-api=vulkan (or equivalent entry in config file):
Error parsing option gpu-api (option parameter could not be parsed)
Setting commandline option --gpu-api=vulkan failed.

re-build with vulkan-icd-loader and vulkan-headers would work, however still depends on an external glsl-spir-v compiler like shaderc.
This task depends upon

nvidia-410.57 removed support of "VK_NV_glsl_shader" extension[1], which makes shaderc the only working spirv-compiler for vulkan support in mpv.

recently "shaderc" gets a stable release[2], but git master version of glslang is currently required. (See [3]).

shaderc is now in repository, so a recompile should add Vulkan support. Could we get one, please? :)

Does an optional dependency suffice or do we need a hard dependency?

Hard dependency, as it is required during compile and won't start with it missing.
