Detect orientation of an iPhone video from server

I am attempting to detect the orientation of an iPhone video file (.mov) on upload through a PHP form so that I can use FFMPEG to correct it (a lot of the videos uploaded are shown on their side). I can not seem to find a way of accessing the orientation of the uploaded file on the server. Any ideas?

I'm not the best with regex but here is how I would go about doing it

exec(ffmpeg -i uploaded.mov,$output)

Then once you have the output do a pregmatch on it, like so

preg_match('/(\d+)x(\d+)/', $output, $dims);

Then check to see if $dims[1] is greater than $dims[2], if it is then it's in landscape, if it's less than its in portrait.

I wasn't able to test it fully but something along those lines should work for you.

Using mediainfo

$ mediainfo test.mp4 | grep Rotation
Rotation                         : 90°

You can use exec() to capture the output of this system call, and apply the orientation fix (90 degrees clockwise):

$ ffmpeg -i test.mp4 -vf "transpose=1" testRotated.mp4

If you have --enable_vfilters

$ ffmpeg -vfilters "rotate=90" -i test.mp4 testRotated.mp4
