Function fdk_aac_sys::aacDecoder_Fill

pub unsafe extern "C" fn aacDecoder_Fill(
    self_: HANDLE_AACDECODER,
    pBuffer: *mut *mut UCHAR,
    bufferSize: *const UINT,
    bytesValid: *mut UINT
) -> AAC_DECODER_ERROR

\brief Fill AAC decoder’s internal input buffer with bitstream data from the external input buffer. The function only copies such data as long as the decoder-internal input buffer is not full. So it grabs whatever it can from pBuffer and returns information (bytesValid) so that at a subsequent call of %aacDecoder_Fill(), the right position in pBuffer can be determined to grab the next data.

\param self AAC decoder handle. \param pBuffer Pointer to external input buffer. \param bufferSize Size of external input buffer. This argument is required because decoder-internally we need the information to calculate the offset to pBuffer, where the next available data is, which is then fed into the decoder-internal buffer (as much as possible). Our example framework implementation fills the buffer at pBuffer again, once it contains no available valid bytes anymore (meaning bytesValid equal 0). \param bytesValid Number of bitstream bytes in the external bitstream buffer that have not yet been copied into the decoder’s internal bitstream buffer by calling this function. The value is updated according to the amount of newly copied bytes. \return Error code.
