How can I fix the problem about QMediaPlayer when used on ARM

[Mihan]

My Project need to play some audio file and control the voice,so I use QMediaPlayer to do that. But when it ran on ARM，it show "defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer" and there is not any voice.
I found some blogs about this problem that they compiled the qtmultimedia-opensource to replace the old one,is that right? Also I compared the plugin of mediaplayer between PC(Linux) and ARM, I found that ARM just has

libqtmedia_audioengine.so

and PC has

libgstaudiodecoder.so  libgstcamerabin.so  libgstmediacapture.so  libgstmediaplayer.so

So I need some help to understand it. Thank you~

Hi,

What version of Qt do you have on your desktop machine ?
What version of Qt do you have on your target ?
How did you install both of them ?
