QtMultimedia (Qt 4.8): adding codecs

[OwonaVivienD]

Hello,

Since, in a near future, Phonon won't be supported anymore, I've decided to start using the QtMultimedia module and to create my own library, whose features will look like Phonon's ones. Firstly I searched codecs which are already supported by Qt and my laptop; that's why I've coded this program:
@#include <QtCore>
#include <QtGui>
#include <QtMultimedia>

int main(int argc, char* argv[])
{
QApplication app(argc, argv);

QTextEdit tE;
QString str;
str.clear();
tE.setReadOnly(true);
tE.show();

QList<QAudioDeviceInfo> adis(QAudioDeviceInfo::availableDevices(QAudio::AudioOutput));
QStringList codecs;

tE.append(QString("<b>Available audio output device(s)</b>"));
for(int i = 0 ; i < adis.size() ; i++)
{
    tE.append(adis.at(i).deviceName());
}
tE.append(QString("<br/>"));

for(int i = 0 ; i < adis.size() ; i++)
{
    str.append("<b>Available codec(s) for ");
    str.append(adis.at(i).deviceName());
    str.append("</b>");
    tE.append(str);
    str.clear();

    codecs = adis.at(i).supportedCodecs();
    while(!codecs.isEmpty())
    {
        tE.append(codecs.takeFirst());
    }

    tE.append(QString("<br/>"));
}

return app.exec();

}@

As you may imagine, I was quite deceived when I saw that only one codec (PCM) was supported. I would also like adding few other codecs, like AAC, FLAC, MPEG and Vorbis. However, I don't know at all how I can do it; and that's why I'm asking for your help.

Thank you in advance.

Adishatz!
