This is a refactored Theora Video Plugin for Ogre (available for download), which is initially was created and currently supported by Kreso (from Ogre forums) but I completely refactored the library and fixed a number of threading issues with the library. Yet the theora and ogg header parsing code was done well, the stability and rendering smoothness left much to be desired. This job took for me a week of work.
So, to conclude the job, to test high resolution video performance I've quickly made the ">temporary video.
