Can't open WWDC 2016 session video

[Peter Hosey]

Whenever I try to open the HD video downloaded from https://developer.apple.com/videos/play/wwdc2016/238/ , I get the following message:

The document “238_hd_measurements_and_units.mp4” could not be opened.

QuickTime Player X on 10.11.4 is able to open the same file and play its video, audio, and closed captions. I've attached a screenshot of QTPX's Inspector panel describing the file's contents.

Those files are actually mov, not mp4, the major brand in the ftyp atom is 'qt ' . There are some small differences between mov and mp4, and Subler can't handle them, so it refuses to open them. Maybe a better error message would be useful.

Fixed in master, now it ask the user to import the file and actually import the closed captions in the new mp4 file.
