opus_multistream_decoder_create method
Allocates and initializes a multistream decoder state.
Call opus_multistream_decoder_destroy() to release
this object when finished.
@param Fs opus_int32: Sampling rate to decode at (in Hz).
This must be one of 8000, 12000, 16000,
24000, or 48000.
@param channels int: Number of channels to output.
This must be at most 255.
It may be different from the number of coded
channels (streams +
coupled_streams).
@param streams int: The total number of streams coded in the
input.
This must be no more than 255.
@param coupled_streams int: Number of streams to decode as coupled
(2 channel) streams.
This must be no larger than the total
number of streams.
Additionally, The total number of
coded channels (streams +
coupled_streams) must be no
more than 255.
@paramin mapping const unsigned char: Mapping from
coded channels to output channels, as described in
@ref opus_multistream.
@paramchannelsout error int *: Returns #OPUS_OK on success, or an error
code (see @ref opus_errorcodes) on
failure.
