Function Documentation

void av_init_random	(	unsigned int	seed,
		AVRandomState *	state
	)

initializes mt[AV_RANDOM_N] with a seed

to be inlined, the struct must be visible, so it doesn't make sense to try and keep it opaque with malloc/free like calls

void av_random_generate_untempered_numbers

(

AVRandomState *

state

)

generate AV_RANDOM_N words at one time (which will then be tempered later) (av_random calls this; you shouldn't)

Regenerate the untempered numbers (must be done every 624 iterations, or it will loop).
