void ff_avfilter_default_free_buffer

(

AVFilterBuffer *

buf

)

default handler for freeing audio/video buffer when there are no references left

int ff_avfilter_graph_check_validity	(	AVFilterGraph *	graphctx,
		AVClass *	log_ctx
	)

Check for the validity of graph.

A graph is considered valid if all its input and output pads are connected.

Returns:

0 in case of success, a negative value otherwise
