Still having problems using the SYNC API when processing Wave files...

Here is the situation:

The decoder_input_open call fails if I'm using a memory input module or a
file input module where the file name does not end in '.wav'.

I had a response on this once before suggesting that I need to set the mime
type

Here is the 'init' code: (the _Source variable is my own enum, it is set to
SourceTypeWave on entry, _pcFile is NULL when I'm going to process from
memory and pointer to the source file when from file)

{
 // create a pXAudioDecoder
 if(decoder_new(&pXAudioDecoder) != XA_SUCCESS)
 {
  SignalError(ErrorDecoderNewError);
  return;
 }

 XA_CodecModule codecModule;

 // register codec
 {
  switch(_Source)
  {
  case SourceTypeMP3:
   // register mpeg audio codec
   mpeg_codec_module_register(&codecModule);
   break;

  case SourceTypeWave:
   // register wave audio codec
   wave_codec_module_register(&codecModule);
   break;

  default:
   SignalError(ErrorDecoderNoCodecError);
   return;
  }

  decoder_codec_module_register(pXAudioDecoder, &codecModule);
 }

 XA_InputModule inputModule;

 // register the input module
 {
  // if using file input
  if (_pcFile != NULL)
  {
   // register the file input module
   file_input_module_register(&inputModule);
  }
  // else, using memory input
  else
  {
   // register the memory input module
   memory_input_module_register(&inputModule);
  }

  decoder_input_module_register(pXAudioDecoder, &inputModule);
 }

 // create input object
 if(decoder_input_new(pXAudioDecoder, _pcFile, XA_DECODER_INPUT_AUTOSELECT)
!= XA_SUCCESS)
 {
  SignalError(ErrorDecoderInputNewError);
  return;
 }

 // set the mime type
 switch(_Source)
 {
 case SourceTypeMP3:
  XAudioSetMimeType(pcMP3MimeType);
  break;

 case SourceTypeWave:
  XAudioSetMimeType(pcWaveMimeType);
  break;

 default:
  SignalError(ErrorDecoderNoCodecError);
  return;
 }

 // open input object - fails here!
 if(decoder_input_open(pXAudioDecoder) != XA_SUCCESS)
 {
  SignalError(ErrorDecoderInputOpenError);
  return;
 }

 // if here, success
 _Status = working;
 return _Status;

End of the 'init' function, here the my XAudioSetMimeType function:

void
InfoFFTIDTagSource::XAudioSetMimeType(const char *pcType)
{
// tried using this at first - no luck!
// decoder_input_send_message(pXAudioDecoder,
XA_MEMORY_INPUT_MESSAGE_SET_MIME_TYPE,
//  pcType, strlen(pcType)+1);

// here is desperate attempt to set the data directly, still no luck!
 if (pXAudioDecoder != NULL)
 {
  if (pXAudioDecoder->input != NULL)
  {
   pXAudioDecoder->input->mime_type = pcUnknownMimeType;
  }

  if (pXAudioDecoder->status != NULL)
  {
   pXAudioDecoder->status->info.mime_type = pcType;
   pXAudioDecoder->status->info.changed =
XA_DECODER_STREAM_MIME_TYPE_CHANGED;
  }
 }
}

This seems so simple but it would really help me out to get this resolved!

Thanks,
-Adam
