Fill plane data pointers and linesize for samples with sample
format sample_fmt.
The audio_data array is filled with the pointers to the samples data planes:
for planar, set the start point of each channel's data within the buffer,
for packed, set the start point of the entire buffer only.
The value pointed to by linesize is set to the aligned size of each
channel's data buffer for planar layout, or to the aligned size of the
buffer for all channels for packed layout.
The buffer in buf must be big enough to contain all the samples
(use av_samples_get_buffer_size() to compute its minimum size),
otherwise the audio_data pointers will point to invalid data.
@see enum AVSampleFormat
The documentation for AVSampleFormat describes the data layout.
