windows Qt 录屏 录音

启动录屏录音：

connect(&m_Process, &QProcess::readyReadStandardOutput, [&]() {qDebug() << "Standard output:" << QString::fromLocal8Bit(m_Process.readAllStandardOutput());
});connect(&m_Process, &QProcess::readyReadStandardError, [&]() {QString qstr = QString::fromLocal8Bit(m_Process.readAllStandardError());qDebug() << "Standard error:" << qstr;
});connect(&m_Process, QOverload<int, QProcess::ExitStatus>::of(&QProcess::finished), [=](int exitCode, QProcess::ExitStatus exitStatus) {qDebug() << "Process finished with exit code" << exitCode << " " << exitStatus;
});//转码参数
QStringList arguments;
arguments << "-f" << "gdigrab"<< "-framerate" << "30"<< "-i" << "desktop"<< "-f" << "dshow"<< "-i" << QString("audio=%1").arg(m_strAudioDeviceName.c_str())<< qstrFolder;m_Process.setProcessChannelMode(QProcess::MergedChannels);
m_Process.start("ffmpeg", arguments);

结束录屏、录音：

if (m_Process.isOpen()) {m_Process.write("q");
}
