Function Documentation

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

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

Definition at line 232 of file asrc_abuffer.c.

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
