Function opus_encoder_init

Source 
pub unsafe extern "C" fn opus_encoder_init(
    st: *mut OpusEncoder,
    Fs: opus_int32,
    channels: c_int,
    application: c_int,
) -> c_int
Expand description

Initializes a previously allocated encoder state The memory pointed to by st must be at least the size returned by opus_encoder_get_size(). This is intended for applications which use their own allocator instead of malloc.

§See also

[opus_encoder_create(),opus_encoder_get_size()] To reset a previously initialized state, use the #OPUS_RESET_STATE CTL.

§Arguments

  • st [in] - OpusEncoder*: Encoder state
  • Fs [in] - opus_int32: Sampling rate of input signal (Hz) This must be one of 8000, 12000, 16000, 24000, or 48000.
  • channels [in] - int: Number of channels (1 or 2) in input signal
  • application [in] - int: Coding mode (one of OPUS_APPLICATION_VOIP, OPUS_APPLICATION_AUDIO, or OPUS_APPLICATION_RESTRICTED_LOWDELAY) @retval #OPUS_OK Success or [opus_errorcodes]
