https://sites.google.com/site/easylinuxtipsproject/multimedia 关于 sudo apt-get install ubuntu-restricted-extras 的，但问题依然没解决
控制台显示如下错误：defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"
执行 $sudo apt install libqt5multimedia5-plugins,故障依然
sudo apt install libgstreamer1.0-0 故障依然
安装 $sudo apt install gstreamer0.10-plugins-base 上述错误消失，错误提示在点击播放按钮后提示：
