Change existing Wordpress plugin project (change the player "videojs" to "jwplayer" in an existing plugin)

I have a wordpress plugin with a technology, but it is adapted to a html5 player called "videojs" that has not been updated for more than 3 years. this is influencing performance and so I need to adapt a new html5 player in technology, making it faster and using the codes already existing in the current plugin. I also need to update the code to work with videos from the vimeo. NOTE: In short, the codes are all ready, you only have to change the integrated player to a newer one.
