defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"

问题

我正在将我的Qt应用程序构建为Ubuntu-22.04上的AppImage。它构建没有错误，并且应用程序可以正常工作。但问题是它应该显示一个视频，但实际上没有显示。初始版本的应用程序可以成功显示视频，但新版本却不能。然而，当我在Qt Creator中以调试模式运行应用程序时，视频可以正常工作。

错误信息是："defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"。

我知道论坛上有很多关于这个错误的主题，但我尝试了所有的方法。
我安装了所有推荐的库：

我甚至使用aqt安装了带有qtmultimedia的Qt：

aqt install-qt --outputdir ./Qt linux desktop 5.15.2 --archives qtmultimedia

如果有人能够提供解决此问题的说明，我将非常感激。

英文:

I'm building my Qt app into an AppImage on Ubuntu-22.04. It builds without errors and the app works. But the problem is that it's supposed to display a video, and it doesn't. The initial version of the app successfully displays the video, but the new version does not. However, the video works correctly when I run the app from Qt Creator in Debug mode.
The error message is:"defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"".

I know there are multiple topics about this error across the forums, but i tried everything.

aqt install-qt --outputdir ./Qt linux desktop 5.15.2 --archives qtmultimedia

If someone could provide me with instructions for resolving this issue, I would greatly appreciate it.

我刚刚不得不将Qt mediaservice文件夹及其插件添加到我的构建插件目录中，然后它就可以工作了。

英文:

UPDATE:
I just had to add the Qt mediaservice folder with its plugins into my build's plugins directory and it worked.
