From 9b2dae79b1be1f57e7b6bcf80d500ab4190aa3d3 Mon Sep 17 00:00:00 2001 From: James Ross-Gowan Date: Mon, 2 Oct 2017 23:10:52 +1100 Subject: vo_gpu: d3d11: add RA caps for ra_d3d11 ra_d3d11 uses the SPIR-V compiler to translate GLSL to SPIR-V, which is then translated to HLSL. This means it always exposes the same GLSL version that the SPIR-V compiler supports (4.50 for shaderc/glslang.) Despite claiming to support GLSL 4.50, some features that are tied to the GLSL version in OpenGL are not supported by ra_d3d11 when targeting legacy Direct3D feature levels. This includes two features that mpv relies on: - Reading from gl_FragCoord in the fragment shader (requires FL 10_0) - textureGather from any texture component (requires FL 11_0) These features have been exposed as new RA caps. --- video/out/gpu/ra.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'video/out/gpu/ra.h') diff --git a/video/out/gpu/ra.h b/video/out/gpu/ra.h index b10ab76124..934e5db844 100644 --- a/video/out/gpu/ra.h +++ b/video/out/gpu/ra.h @@ -51,6 +51,8 @@ enum { RA_CAP_BUF_RW = 1 << 6, // supports RA_VARTYPE_BUF_RW RA_CAP_NESTED_ARRAY = 1 << 7, // supports nested arrays RA_CAP_GLOBAL_UNIFORM = 1 << 8, // supports using "naked" uniforms (not UBO) + RA_CAP_GATHER = 1 << 9, // supports textureGather in GLSL + RA_CAP_FRAGCOORD = 1 << 10, // supports reading from gl_FragCoord }; enum ra_ctype { -- cgit v1.2.3
