gst_audio_resampler_resample

gst_audio_resampler_resample (GstAudioResampler * resampler,
                              gpointer * in,
                              gsize in_frames,

                              gsize out_frames)

Perform resampling on in_frames frames in in and write out_frames to out.

In case the samples are interleaved, in and out must point to an array with a single element pointing to a block of interleaved samples.

If non-interleaved samples are used, in and out must point to an array with pointers to memory blocks, one for each channel.

in may be NULL, in which case in_frames of silence samples are pushed into the resampler.

This function always produces out_frames of output and consumes in_frames of input. Use gst_audio_resampler_get_out_frames and gst_audio_resampler_get_in_frames to make sure in_frames and out_frames are matching and in and out point to enough memory.

Parameters:

resampler –

in –

input samples

in_frames –

number of input frames

out –

output samples

out_frames –

number of output frames
