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.
