QProcess output like terminal emulator

I'm starting youtube-dl app from QProcess to get the ouput log into a QListWidget. I ran into the problem about how to process the data, here is the important code:

void MyQtYoutubedl::myprocessreadStdOutput () {
    QProcess *_refProcess = m_Process.data();
    QTextStream stream(_refProcess);
    while (!stream.atEnd()) {
        QString line = stream.readLine();
        ui->logWidget->addItem (line.simplified());
    }
}

I'm not having problems with launched app, is how to propertly show it in the QListWidget, because I'm getting this type of output:
