Comment (by Jayjdk):

 I can reproduce this in Safari and Firefox on Mac (haven't tried Windows).
 It works in Chrome.

 And it's not just in TwentyFourteen. Every theme I've tried has the same
 problem.

 The console in Firefox gives these errors:
 - `Specified "type" attribute of "video/youtube" is not supported. Load of
 media resource https://www.youtube.com/watch?v=[...] failed.`
 - `All candidate resources failed to load. Media load paused.`

 The console in Safari gives this error:
 * `Blocked a frame with origin "https://www.youtube.com" from accessing a
 frame with origin "http://theme.dev".  The frame requesting access has a
 protocol of "about", the frame being accessed has a protocol of "http".
 Protocols must match.`
