opus_projection_decoder_create method

Pointer<OpusProjectionDecoder> opus_projection_decoder_create(
  1. int Fs,
  2. int channels,
  3. int streams,
  4. int coupled_streams,
  5. Pointer<Uint8> demixing_matrix,
  6. int demixing_matrix_size,
  7. Pointer<Int32> error,
)

Allocates and initializes a projection decoder state. Call opus_projection_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 demixing_matrix const unsigned chardemixing_matrix_size: Demixing matrix that mapping from coded channels to output channels, as described in @ref opus_projection and @ref opus_projection_ctls. @param demixing_matrix_size opus_int32: The size in bytes of the demixing matrix, as described in @ref opus_projection_ctls. @paramout error int *: Returns #OPUS_OK on success, or an error code (see @ref opus_errorcodes) on failure.
