Output texture of d3d11 decoder cannot have the bind flag D3D11_BIND_SHADER_RESOURCE (meaning that it cannot be used for shader input resource). So d3d11convert (and it's subclasses) was copying texture into another internal texture to use d3d11 shader. It's obviously overhead and we can avoid texture copy for colorspace conversion or resizing via ID3D11VideoProcessor as it supports decoder output texture. This commit would be a visible optimization for d3d11 decoder with d3d11compositor use case because we can avoid texture copy per frame.
