I'm aware of this issue, but I think it would be better to auto-insert the
corresponding hw rotation filters, as a user should be able to expect the
same result, no matter whether using sw or hw filtering.
It is already possible to specify
-autorotate 0
to prevent autorotation, which applies to all cases equally.
