vaapi and d3d11va are safe. Enabling deinterlacing (or simply their respective
post-processing filters) will possibly at least reduce color quality by converting the output to a 8
bit format.
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. |
