SKP_Silk_SDK_Decode

static int SKP_Silk_SDK_Decode(Object decState,
                               SKP_SILK_SDK_DecControlStruct decControl,
                               int lostFlag,
                               byte[] inData,
                               int inData_offset,
                               int nBytesIn,
                               short[] samplesOut,

                               short[] nSamplesOut)

Decode a frame.

Parameters:

decState - the decoder state.

decControl - the decoder control.

lostFlag - the lost flag. 0: no loss; 1: loss.

inData - encoding input vector.

inData_offset - the actual data offset in the input vector.
