opus_projection_encode method

int opus_projection_encode(
  1. Pointer<OpusProjectionEncoder> st,
  2. Pointer<Int16> pcm,
  3. int frame_size,
  4. Pointer<Uint8> data,
  5. int max_data_bytes,
)

Encodes a projection Opus frame. @param st OpusProjectionEncoder*: Projection encoder state. @paramin pcm const opus_int16*: The input signal as interleaved samples. This must contain frame_sizechannels samples. @param frame_size int: Number of samples per channel in the input signal. This must be an Opus frame size for the encoder's sampling rate. For example, at 48 kHz the permitted values are 120, 240, 480, 960, 1920, and 2880. Passing in a duration of less than 10 ms (480 samples at 48 kHz) will prevent the encoder from using the LPC or hybrid modes. @paramout data unsigned char: Output payload. This must contain storage for at least a max_data_bytes. @param in max_data_bytes opus_int32: Size of the allocated memory for the output payload. This may be used to impose an upper limit on the instant bitrate, but should not be used as the only bitrate control. Use #OPUS_SET_BITRATE to control the bitrate. @returns The length of the encoded packet (in bytes) on success or a negative error code (see @ref opus_errorcodes) on failure.
