You originally reported different problems, one of them -
that I was not aware of and that was not reported before -
was that if you explicitly rotate iPhone videos using -vf
transpose Safari (and I assumed QuickTime) show the resulting
video incorrectly (rotated).
I only commented on this issue (I wanted to spare you my
comment <<What is "inactive" about trac tickets?>>), I even
tried to fix it (which turned out to be non-trivial), and I
finally provided the solution (not found by me).

Because ticket #515 was not fixed yet, feel free to add
yourself to CC or send a patch.
