Detailed Description

memory buffer source for audio

Deprecated:

use buffersrc.h instead.

Definition in file asrc_abuffer.h.

Function Documentation

attribute_deprecated int av_asrc_buffer_add_audio_buffer_ref	(	AVFilterContext *	abuffersrc,
		AVFilterBufferRef *	samplesref,
		int av_unused	flags
	)

Queue an audio buffer to the audio buffer source.

Parameters

abuffersrc	audio source buffer context
samplesref	buffer ref to queue
flags	unused

Deprecated:

use av_buffersrc_add_ref() instead.

attribute_deprecated int av_asrc_buffer_add_buffer	(	AVFilterContext *	abuffersrc,
		uint8_t *	buf,
		int	buf_size,
		int	sample_rate,
		int	sample_fmt,
		int64_t	ch_layout,
		int	planar,
		int64_t	pts,
		int av_unused	flags
	)

Queue an audio buffer to the audio buffer source.

This is similar to av_asrc_buffer_add_samples(), but the samples are stored in a buffer with known size.

Parameters

abuffersrc	audio source buffer context
buf	pointer to the samples data, packed is assumed
size	the size in bytes of the buffer, it must contain an integer number of samples
sample_fmt	sample format of the audio data
ch_layout	channel layout of the audio data
pts	presentation timestamp of the audio buffer
flags	unused

Deprecated:

use av_buffersrc_add_ref() instead.

attribute_deprecated int av_asrc_buffer_add_samples	(	AVFilterContext *	abuffersrc,
		uint8_t *	data[8],
		int	linesize[8],
		int	nb_samples,
		int	sample_rate,
		int	sample_fmt,
		int64_t	ch_layout,
		int	planar,
		int64_t	pts,
		int av_unused	flags
	)

Queue an audio buffer to the audio buffer source.

Parameters

abuffersrc	audio source buffer context
data	pointers to the samples planes
linesize	linesizes of each audio buffer plane
nb_samples	number of samples per channel
sample_fmt	sample format of the audio data
ch_layout	channel layout of the audio data
planar	flag to indicate if audio data is planar or packed
pts	presentation timestamp of the audio buffer
flags	unused

Deprecated:

use av_buffersrc_add_ref() instead.
