Multimedia Embedder is plugin that allows user to embed multimedia just like 
oEmbed, but with the added convenient of an HTML template system, each site has 
at least one template each for example Flickr will have two templates (photo 
and video). The users will get full control of the HTML template, for example 
the YouTube template can be modified to embed YouTube into JW Player rather than 
using YouTube default player.
This plugin also utilise HTML DOM to fetch Meta tag and other vital data about 
the media in question, if there is not enough data it will use the data from 
oEmbed as the last resort, all the collected data will get stored to the 
database for maximum speed and efficiency.
This plugin extends on WordPress Embed, so therefore it embedded the same way as 
oEmbed and requires PHP 5.3 and above.
