Can Popcorn.js be used to add subtitles to a YouTube video?

Let's say we embed a YouTube video on a web page.

Underneath the video player, could we display subtitles synched to the video using a media framework lik开发者_如何学JAVAe Popcorn.js?

Interesting you mentioned Popcorn.js, because Popcorn does support Youtube.

Buuut, that documentation is out of date.

It is now:

"var example = Popcorn.youtube("

There are new docs on their way.

If you choose the HTML5 version when embedding the YouTube video and if it's actually being played within an HTML5 browser, it's just a video tag so you can use Popcorn.js. When it's a Flash, I'm not sure if you can get into that Flash and know the progress and listen to the events.

If you use the YouTube JavaScript Player API, you can use player.getCurrentTime() to find out which line of subtitling to show.

Then again, YouTube already supports subtitles to begin with.
