Totally agree. But correct way of doing this is to tag yuv format as 709 if it is tagged as 709 in the file. There is no conflict here.
(VirtualDubs 709/601 and FR format variations are essentially tags).
We can talk about my driver instead of abstract one
I tried to preserve image bytes and pass correct tags when possible. So that if tags are available there is no intervention needed (no need to select input format or alias filter) and otherwise at least the bytes are not destroyed before reaching filters etc.

If it is tagged as 709, then it is always converted to rgb as 709, whichever reason for conversion (at least latest code works that way).
