#include "avfilter.h"

Macros
#define	AV_BUFFERSINK_FLAG_PEEK 1
	Tell av_buffersink_get_buffer_ref() to read video/samples buffer reference, but not remove it from the buffer. More...

#define	AV_BUFFERSINK_FLAG_NO_REQUEST 2
	Tell av_buffersink_get_buffer_ref() not to request a frame from its input. More...

Typedefs
typedef AVFrame *	av_buffersink_alloc_video_frame(AVFilterContext ctx, void v, int w, int h)

Functions
int	av_buffersink_get_frame_flags (AVFilterContext ctx, AVFrame frame, int flags)
	Get a frame with filtered data from sink and put it in frame. More...

void	av_buffersink_set_frame_size (AVFilterContext *ctx, unsigned frame_size)
	Set the frame size for an audio buffer sink. More...

int	av_buffersink_get_frame (AVFilterContext ctx, AVFrame frame)
	Get a frame with filtered data from sink and put it in frame. More...

int	av_buffersink_get_samples (AVFilterContext ctx, AVFrame frame, int nb_samples)
	Same as av_buffersink_get_frame(), but with the ability to specify the number of samples read. More...
