Precompiled Vulkan compute shaders for GPU-accelerated color format conversion.

color_convert.comp — RGB → YUV compute shader. Converts BGRx/RGBx/BGRA/RGBA/ABGR2101010/RGBA16F input to NV12/I420/YUV444/P010/YUV444P10 output using BT.709, BT.2020, or sRGB→BT.2020+PQ color space matrices.

Requires glslc from the Vulkan SDK.

./compile.sh

This compiles both shaders to SPIR-V 1.6 (Vulkan 1.3, optimized). The .spv files are included in source via include_bytes!, so rerun this after editing a .comp and commit the result.

The examples carry one more, outside the library: examples/shader/sample_frame.comp reads a decoded frame through a sampler-YCbCr conversion and writes RGBA, which is what examples/sample_frame.rs uses to show the zero-copy render path.
