Thanks for the comments. The MFXSurface is based on VaSurface on Linux and D3D texture on Windows. Since the QSV encoder can accept AV_PIX_FMT_QSV as input, it seems kind of reasonable to accept VAAPI and D3D as its input. And it just may not look like a 'real' trick, let's say, for example, make QSV encoder accept VULKAN format directly. By adding this patch, we just want QSV encoder have more input format supports like what nvenc does. Plus, this patch can really help the users who have hybrid transcode needs.
