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
