[FFmpeg-user] Flipping Iphone videos

Hi guys,

I took a video from my iphone5, had dropbox upload it. Then on my
server I encoded into mp4/webm using
https://github.com/kaihendry/recordmydesktop2.0

However it appeared upside down when I tried to view either the
mp4/webm: http://r2d2.webconverger.org/2012-11-14/silent-boot-not-flipped.html

Ok, I'll flip it then, which I did in:
http://r2d2.webconverger.org/2012-11-14/silent-boot.html
However that version appears upside down for Safari users. Not winning.


So does anyone know where this flipping problem lies? FFMPEG, Safari or Chrome?


I did search around and I found a couple of inactive bugs:
https://ffmpeg.org/trac/ffmpeg/ticket/1423
https://ffmpeg.org/trac/ffmpeg/ticket/515

The original file is here:
http://r2d2.webconverger.org/2012-11-14/silent-boot.mov

I hope someone can help with this frustrating problem! Many thanks,
