Comment (by hendry):

 I'm suffering from this rotation issue WRT Iphone5 videos I take. They are
 upside down once I've transcoded them. If I do rotate them (which I should
 not have to do!), then they appear upside down on Safari.

 Here is the original movie from my iphone that exhibits the problem with
 the very latest ffmpeg: http://r2d2.webconverger.org/2012-11-14/silent-
 boot.mov

 I'm *guessing* there is some rotation metadata like what a JPEG stores
 which some players don't respect?
