There is a developer who forked MPlayer and added threading support.
The project is still maintained under the name MPlayerXP on
sourceforge.net site.

Threading support is quite hard subject.
Whatever solution you may have in mind you should know that MPlayer
should remain single threaded on uniprocessor machines.
