#include <avfilter.h>

Data Fields
uint64_t	channel_layout

	number of audio samples per channel
int	sample_rate
	audio buffer sample rate
int	planar
	audio buffer - planar or packed

Detailed Description

Audio specific properties in a reference to an AVFilterBuffer.

Since AVFilterBufferRef is common to different media formats, audio specific per reference properties must be separated out.
