The initialization order change to support captions moved the acorn
initialization to after some of the popcorn init had already run. We
have to move that function to run after we create the acorn player
so it references the correct #video element (since acorn replaces/
moves it during init)

In some cases, ffmpeg will be able to read the file, but the video itself
can't be decoded (missing/corrupt stream headers, for example). In this case,
some of the properties on the stream object will be nil.
Make sure that pix_fmt is present in the probed info, since that's a required
property.

Previously, the acorn player was being initialized before the asynchronous
load of captions information completed, meaning that the acorn player didn't
know there were caption tracks, and the CC selector control wasn't available.
