Kreso made something nice and I want to help him spread the word a bit. :3
QuoteYou can use the Theora Playback Library to stream any number of Ogg theora video files in your application. The library has an abstracted audio and video interface so you can use it in any environment you wish (OpenGL, DirectX, SDL, Windows GDI, X11...). It runs equally good on Windows Mac and Linux, i386, x64 and PowerPC. Bug reports and features requests are welcome. Please spread word of this project!
