title: Get orientation of HTML5 video
body: <p>I've spotted something strange happening. I have an MP4 file that was recorded using an android phone which I am embedding on the page to play using the HTML5 video tag. If I play it in chrome the video is upside down however if I view the same page in chrome on my phone the video plays the correct way round. Is there some sort of orientation meta value that the phone is reading and the desktop browser isn't? Obviously I want it to play the right way round in all browsers so is there a way I can work out which way round it is meant to be displayed either on the client side or with PHP on the server side?</p>
