Re: [Tjukebox-general] audio to stdout

[Kevin N. <bea...@ya...>]

I disabled all of the status updates the server was
printing out.  Here's the snippit of code I was given:

  const char *fname = p.string().c_str();
  Sound_Sample * sample = Sound_NewSampleFromFile
(fname, NULL, 
1024*64);
  if (!sample) {
      cerr << "Error opening " << fname << ": " <<
Sound_GetError();
      return;
  }

  do {
      Uint32 br = Sound_Decode(sample);
      if (br > 0)  // write this block of decoded data
to stdout.
          cout.write((const char *) sample->buffer, 
sample->buffer_size);

      if (sample->flags & SOUND_SAMPLEFLAG_ERROR) {
          cerr << "Error decoding " << fname << ": "
<< 
Sound_GetError();
          break;
      }
  } while (sound->flags & SOUND_SAMPLEFLAG_EOF);

  Sound_FreeSample(sample);


I believe the line "sound->flags" is supposed to be
sample->flags.

I'm also wondering if this needs to be in a loop.  The
NewSampleFromFile function may only be returning part
of the file.

I'll experiment and I guess I'll probably write back
to the list explaining that a stream to my audio
device doesn't work, unless you come up with any
ideas.
