[CLAM] What's wrong with my code

[Stephane THOMAS]

Hi,

Here is another program I wrote from scratch (the goal is to get a command line program which plays a stereo file through JACK)

It produces sound, but once again, I have a repeated error message and the sound is awful :

Warning: 2 sinks were not fed, so could not send audio to the callback.

The program is called cjap (for CLAM JACK Audio Player), here is the code :

-----------cjap.h--------------
#include <QObject>
#include "CLAM/Network.hxx"
#include "CLAM/AudioSink.hxx"
#include "CLAM/MultiChannelAudioFileReader.hxx"
#include "CLAM/JACKNetworkPlayer.hxx"

using namespace std;
using namespace CLAM;


class JackAudioFilePlayer : QObject
{
Q_OBJECT
 Network network;
 AudioSink sinkL;
 AudioSink sinkR;
 MultiChannelAudioFileReader reader;
 MultiChannelAudioFileReaderConfig config;
 JACKNetworkPlayer player;

public:
JackAudioFilePlayer ();
void loadfile (string filename);

public slots:
void play ();
void stop ();
};
---------------------------------

-------------cjap.cpp------------------
#include "cjap.h"

JackAudioFilePlayer::JackAudioFilePlayer ()
{
 network.AddProcessing("left",&sinkL);
 network.AddProcessing("right",&sinkR);
 network.AddProcessing("reader",&reader);
}

void JackAudioFilePlayer::loadfile (string filename)
{
 config.SetSourceFile(filename);
 reader.Configure (config);
 network.ConnectPorts("reader.Channel #0","left.AudioIn");
 network.ConnectPorts("reader.Channel #1","right.AudioIn");
 network.SetPlayer (&player);
}

void JackAudioFilePlayer::play ()
{
 network.Start();
}

void JackAudioFilePlayer::stop ()
{
 network.Stop();
}
------------------------------------------
----------main.cpp-----------------------
#include <iostream>
#include <QCoreApplication>
#include "cjap.h"

using namespace std;


int main (int argc, char** argv)
{
 QCoreApplication app (argc,argv);
 
 if (argc != 2)
  {
    cout << "Usage: cjap <filename>" << endl;
    return 0;
  }
 else
  {
    JackAudioFilePlayer* jafp = new JackAudioFilePlayer;
    jafp->loadfile(argv[1]);
    jafp->play();
  }
 

 return app.exec();
}
