// Description: Initialize spdif DD parser. Assigned command buffers for
//              parsed frames. cmdbuf size is MAX_DD_BUFSIZE * CMDBUF_NUMBER.
// Parameters:  cmdbuf -    buffer for parsed DD frames
//              callback -  callback function used to bypass parsed DD frame
//                          buffer, frame size, presentation timestamp and
//                          private data.
//              cb_param -  private data which is used in callback function
//                          function
// Return:      none

//              inbufsz -   input IEC60958 buffer size
//              timestamp - presentation timestamp for input IEC60958 buffer
// Return:      none
