I also am not accepting a hardcoded timebase of microseconds.
Rounding really matters for subtitles, since presenting them
a frame early or late is unacceptable
That's simply not true.
I don't accept or deny a hardcoded microseconds timebase;
that's beyond my knowledge to judge. What I say is n

The cases in which there was flipping together with a rotation
that is not a multiple of the identity were wrong.

This whole patchset relies on the mismatch in av_display_rotation_set()
being solved by keeping the current behaviour and updating the
documentat
In case of an orthogonal transformation av_display_rotation_get()
returns the (anticlockwise) degree that the unit vector in x-direction
gets rotated by; get_rotation in cmdutils.c makes a clockwise degree
out of this. So if one inserts a transpose filter corresponding to
this degree, then the x-ve
The transpose filter has modes equivalent to "rotation by 90°/270°"
followed by horizontal flips.

The earlier code did not account for the fact that
av_display_rotation_set() wants the angle in the anticlockwise
direction (despite what its documentation stated for a long time);
furthermore, the H.2645 spec wants the flips applied first,
whereas our code did it the other way around. This can be
