Fields

init: Option<unsafe extern "C" fn(codec: SPXCODECCTYPE, inputSamplesPerSecond: u32, inputBitsPerSample: u8, inputChannels: u8, datacallback: AUDIO_ENCODER_ONENCODEDDATA, pContext: *mut c_void) -> AZACHR>

@param codec codec Object returned by the codec_create call to be initialized @param inputSamplesPerSecond sample rate for the input audio @param inputBitsPerSample bits per sample for the input audio @param inputChannels number of channel of the input audio @param dataCallback An application defined callback. @param pContext A pointer to the application-defined callback context. @return A return code or zero if successful.

get_format_type: Option<unsafe extern "C" fn(codec: SPXCODECCTYPE, buffer: *mut c_char, buffersize: *mut u64) -> AZACHR>

@param codec codec object returned by the codec_create call. @param buffer caller provided buffer to receive the value of the property @param buffersize buffer size. If buffer is passed as null it will return the required buffer size. @return A return code or zero if successful.

encode: Option<unsafe extern "C" fn(codec: SPXCODECCTYPE, pBuffer: *const u8, bytesToWrite: size_t) -> AZACHR>

Encodes raw PCM data. @param codec codec object returned by the codec_create call. @param pBuffer The PCM data. @param bytesToWrite The length pBuffer. @return A return code or zero if successful.

flush: Option<unsafe extern "C" fn(codec: SPXCODECCTYPE) -> AZACHR>

Flushes the encoder. @param codec codec object returned by the codec_create call. @return A return code or zero if successful.

endstream: Option<unsafe extern "C" fn(codec: SPXCODECCTYPE) -> AZACHR>

Terminate the encoded stream immediately @param codec codec object returned by the codec_create call. @return A return code or zero if successful.

destroy: Option<unsafe extern "C" fn(codec: SPXCODECCTYPE) -> AZACHR>

Destroys the encoder. The codec object should not be used anymore after this call. @param codec codec object returned by the codec_create call. @return A return code or zero if successful.
