Free a previously allocated #GstAudioResampler resampler.
Get the number of input frames that would currently be needed
to produce out_frames from resampler.
number of input frames
Get the maximum number of input samples that the resampler would need before producing output.
Get the number of output frames that would be currently available when
in_frames are given to resampler.
number of input 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.

Reset resampler to the state it was when it was first created, discarding
all sample history.
Update the resampler parameters for resampler. This function should
not be called concurrently with any other function on resampler.
When in_rate or out_rate is 0, its value is unchanged.
When options is %NULL, the previously configured options are reused.
