Calling player.poster('path/to/image') throws js error in Firebug

[smohadjer]

In v4.4.0 calling .poster('path/to/img') updates poster, however only when I use video.dev.js. If I use video.js I see errors thrown in Win7 Firefox:

TypeError: a.i[c] is not a function
http://localhost/roche.com_video-js/resources/modules/video-js/video.js
Line 52

Can you look into this?

I can confirm this. It needs to be added to the exports.
