AVABufferSinkParams* av_abuffersink_params_alloc

(

void

)

Create an AVABufferSinkParams structure.

Must be freed with av_free().

Definition at line 42 of file sink_buffer.c.

int av_buffersink_get_buffer_ref	(	AVFilterContext *	buffer_sink,
		AVFilterBufferRef **	bufref,
		int	flags
	)

Get an audio/video buffer data from buffer_sink and put it in bufref.

This function works with both audio and video buffer sinks.

Parameters:

	buffer_sink	pointer to a buffersink or abuffersink context
	flags	a combination of AV_BUFFERSINK_FLAG_* flags

Returns:

>= 0 in case of success, a negative AVERROR code in case of failure
