WordPress 3.6 is not far away:
As I understand it, MediaElement.js will be part of the WP core. Do you know what will happen with reference to the video player skin? Will we keep the same video player design or will it change?
Most probably we would allow WordPress to take over that part and keep a fallback for older versions of WordPress till everyone’s on 3.6+
Yes, it does make sense to make use of the features built in to WP. Thanks for letting me know!
