Data Structures
struct	DecimateContext
Functions
static int	diff_planes (AVFilterContext *ctx, uint8_t *cur, uint8_t *ref, int linesize, int w, int h)
	Return 1 if the two planes are different, 0 otherwise.
static int	decimate_frame (AVFilterContext *ctx, AVFilterBufferRef *cur, AVFilterBufferRef *ref)
	Tell if the frame should be decimated, for example if it is no much different with respect to the reference frame ref.
