Loading a movie
If you want to load movies, you need to inherit from EM_SHARED_VIDEO_DECODER_FACTORY. One can now access the singleton video_decoder_factory, which allows you to load movies. Movie file may be one of the supported files.
One will use create_video_decoder_from_file, which takes the filename as an argument. This will create a EM_VIDEO_DECODER in last_video_decoder, if the file isn't supported an exception will be thrown.
