dynamic - Javascript To Change Metadata / Metatags Dynamically

I'll describe what I'm trying to accomplish and if it seems that my method is dumb please feel free to let me know:

I have a page with a video gallery and a flash video player iframe. When the user clicks on a video thumbnail, it starts to play in the frame.

Users can also go to the page with a specific video loaded into the iframe by appending the filepath to the end of the url - blabla.com/videogallery?videofilepath. I set this up so that videos could be shared easily.

I want to be able to add Share buttons for facebook/twitter, but I cannot get them to work and present themselves properly with the correct metadata (image and title).

So I was thinking of putting the Share buttons in the player iframe as well and then update the metadata tags dynamically when a video change occurs, but am unsure as to how to go about this.

Any help would be much appreciated, thanks.

You wanna do something like this in the code for jQuery

$(document).ready(function(){
    $('title').text("Your new title tag here");
    $('meta[name=description]').attr('content', 'new Meta Description here');
});
