Use QProcess.

hi guys..

i use this code to play music with VLC

QString prog = "vlc";
        QStringList arguments;
        arguments<< "play" << "/home/zakis/dokimi/sound/./ll.pls";
        QProcess* process = new QProcess(this);
        process->start(prog , arguments);
        process->waitForFinished();
        process->close();

QString prog = "vlc";
        QStringList arguments;
        arguments<< "play" << "/home/zakis/dokimi/sound/./ll.pls";
        QProcess* process = new QProcess(this);
        process->start(prog , arguments);
        process->waitForFinished();
        process->close();

To copy to clipboard, switch view to plain text mode 

how i close the vlc to continue my app?

You don't. You can kill it of course, if you want but VLC is probably a quite bad way of playing music from within your application. Phonon would be much better (which is what VLC is probably using too).

thanks again ...
I read about the Phonon library but it's big for my job
Finally install NAS and use the QSound
