好吧。
关于dxva2和copyback的差别，引一段mpv manual里的描述：
dxva2 is not safe. It appears to always use BT.601 for forced RGB conversion, but actual behavior depends on the GPU drivers. Some drivers appear to convert to limited range RGB, which gives a faded appearance. In addition to driver-specific behavior, global system settings might affect this additionally. This can give incorrect results even with completely ordinary video sources.
All other methods, in particular the copy-back methods (like dxva2-copy etc.) should hopefully be safe, although they can still cause random decoding issues. At the very least, they shouldn't affect the colors of the image.
