No, there isn't.
You can easily include the main script
mojoBasePage basePage = Page as mojoBasePage;
basePage.ScriptConfig.IncludejPlayer = true;
but you would have to wire up your own instance of the player and setup the videos.
The only work I have done is I made a jPlayerPanel control that can wire up jplayer for any links inside the panel that end with .mp3
I was only working on mp3 files at the time for use in WebStore for playing the teaser files if selling mp3 downloads.
The control could be evolved to support more media types or you could make your own control borrowing some code from there.
