typedef struct {
	int *supportedInOutFormatPairs; 
	int (*init)(char *args, int inFormat, int outFormat);
	int (*filter)(mp_video_surface_t *src, mp_video_surface_t *dst, 
		      void *privateData);
	char *filterName;
	char *author;
	...
} filterDescriptor_t;

using such a struct would allow easy adding of new filters (only a pointer to 
the structure would be needed to add the filter), 

multiple filter chains would be cool to, it would allow us to combine / blend 
multiple movies and such stuff someday

... changeing the number of frames / framerate (framerate converting filters) 
would be nice too

what about dynamic loading?
