I'm not sure how the rotate API works, but I tried the above command
upon: http://r2d2.webconverger.org/2012-11-15/silent-boot-flipped-metadata.html

Now everything is upside down .... ?


As mentioned before, I still don't understand why I have to manually
flip Iphone videos. There is obviously some metadata not being grokked
correctly by something ... reminds me image viewers mishandling JPEG
EXIF rotation data of yore.
