--- Comment #4 from Sean Aye <sean at wandrnow.com> ---
This also causes issues with capturing video thumbnails. Users also can upload videos and we show a thumbnail preview of the video before upload. 

AFAIK the only way to show this thumbnail from a File is to play the video in a hidden video element then capture an image via `canvas.getContext('2d').drawImage(video, 0, 0, canvas.width, canvas.height)`.

This method for video thumbnail capture only works if the file can be played programmatically via javascript. Therefore video thumbnails cannot be captured if a device is on low power mode
