rotate video in iOS with fully compatible with any player

Question

I want to rotate video file . for that I find a way

using AVMutableVidoeCompositionLayerInstruction method setTransform: AtTime:
- Will this approach rotate the every frame of video or simply set the transform matrix property in video header file ?

if this add transform matrix to header instead of rotating avery frame of video then I am afraid for portability in others players.

what is the best way to rotate an video with portability ?

Thanks

What do you mean by "portability"? – Alex Sorokoletov Aug 09 '14 at 20:29 — Alex Sorokoletov, Aug 09 '14 at 20:29
