opus_projection_ambisonics_encoder_init method

int opus_projection_ambisonics_encoder_init(Pointer<OpusProjectionEncoder> st, int Fs, int channels, int mapping_family, Pointer<Int32> streams, Pointer<Int32> coupled_streams, int application,)

Initialize a previously allocated projection encoder state. The memory pointed to by a st must be at least the size returned by opus_projection_ambisonics_encoder_get_size(). This is intended for applications which use their own allocator instead of malloc. To reset a previously initialized state, use the #OPUS_RESET_STATE CTL. @see opus_projection_ambisonics_encoder_create @see opus_projection_ambisonics_encoder_get_size @param st OpusProjectionEncoder*: Projection encoder state to initialize. @param Fs opus_int32: Sampling rate of the input signal (in Hz). This must be one of 8000, 12000, 16000, 24000, or 48000. @param channels int: Number of channels in the input signal. This must be at most 255. It may be greater than the number of coded channels (streams + coupled_streams). @param streams int: The total number of streams to encode from the input. This must be no more than the number of channels. @param coupled_streams int: Number of coupled (2 channel) streams to encode. This must be no larger than the total number of streams. Additionally, The total number of encoded channels (streams + coupled_streams) must be no more than the number of input channels. @param application int: The target encoder application. This must be one of the following:

#OPUS_APPLICATION_VOIP

Process signal for improved speech intelligibility.

#OPUS_APPLICATION_AUDIO

Favor faithfulness to the original input.

#OPUS_APPLICATION_RESTRICTED_LOWDELAY

Configure the minimum possible coding delay by disabling certain modes of operation.

@returns #OPUS_OK on success, or an error code (see @ref opus_errorcodes) on failure.
