Get windows cmd outputs

ekato993

I have the following code:

//this code run the ffmpeg code perfectly
void MainWindow::on_pushButton_videoFormatConverter_clicked()
{
    QStringList input = QFileDialog::getOpenFileNames();
    qDebug().noquote() << input[0];

    int lastForwardSlashIdx = input[0].lastIndexOf('/');
    int lastDotIdx = input[0].lastIndexOf('.');

    QString inputPath = input[0].left(lastForwardSlashIdx + 1);
    qDebug().noquote() << inputPath;

    QStringList inputFileName;
    QStringList inputFileExtension;
    for(int i = 0; i < input.size(); ++i) {
        inputFileName.push_back(input[i].mid(lastForwardSlashIdx + 1, lastDotIdx - lastForwardSlashIdx - 1));
        inputFileExtension.push_back(input[i].right(input[i].length() - lastDotIdx - 1));
        qDebug().noquote() << inputFileName[i];
        qDebug().noquote() << inputFileExtension[i];
    }

    QString outputPath = inputPath + "outputs";
    QDir outputFolder;
    outputFolder.mkpath(outputPath);

    QString ffmpegInput;
    QString ffmpegOutput;
    for(int i = 0; i < input.length(); ++i) {
        ffmpegInput += " -i \"" + inputPath + inputFileName[i] + "." + inputFileExtension[i] + "\" ";
        ffmpegOutput += " \"" + outputPath + "/" + inputFileName[i] + ".mkv\" ";
    }

    QString ffmpegCode = "ffmpeg " + ffmpegInput + ffmpegOutput;
    qDebug().noquote() << ffmpegCode;


    QProcess process;
    process.execute(ffmpegCode);

}

When I run the ffmpeg with win cmd I get outputs, it changes over time. I would like to get this output to a Qt textbox.

readyReadStandardOutput() will do it.

and of course you already know that text uses <CR> only to overwrite the line as it updates? wreaks bloody havoc on processing wrapper scripts.
