Here is an example of an issue with quicktime movie captured from an iPhone while rotated 180° will be corrected in the video element, however when trying to drawImage to canvas, only the currentTime = 0 will ever be drawn. 

See this example: https://codepen.io/jordanaustin/pen/VwYzmGw

Capture image, then seek past currentTime = 0 and you'll still only get the image from the video elements first frame.
