class OSMPlayer in MediaFront 7

PHP wrapper class for the Open Standard Media (OSM) player.

This class is used to wrap all the functionality behind the open standard media player including the dynamic template system that this unique player employs. This class can be used to easily add and customize the OSM Player within a standalone PHP implementation.
