Seungha Yang	c57fe82a93	d3d11: Implement helper object for converter ... This object will upload system memory to GPU and preprocess texture using compute shader or software converter if needed Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5691>	2023-11-20 20:29:13 +09:00
Seungha Yang	f52ecb9607	d3d11converter: Add support for HLSL precompile and bytecode caching ... Precompile pixel shaders for simple conversion path (without gamma/primaries conversion) in case of MSVC build. Even if runtime compile is required (cross-compiled or complex conversion path), do it only once and reuse the compiled bytecode. This precompile/caching can save about 95% of time taken by gst_d3d11_converter_new() call.
