QMedia player not working

@Bonnie said in QMedia player not working:

Is there any plugin-related info?

except that I see no information there

SGaist

You should have a list of all the plugins that are getting scanned and loaded.

architect23

@SGaist ,how to get this list, which team?

how to get this list

If you set QT_DEBUG_PLUGINS and then start your app you will get it as output of your app. See https://doc.qt.io/qt-5/deployment-plugins.html
If you start your app from QtCreator then set it in Run settings of your project.
If you start it in a terminal then set the variable there and then start your app.

@architect23 Did you build in debug mode? It looks like it does not find debug versions of some DLLs.
Try to build in release mode and see whether it works then.

@jsulm in Release:

@architect23 It still tries to load debug DLLs.
Did you a complete rebuild after switching to release mode?

@architect23 , problem is SOLVED
need install Windows_MediaFeaturePack_x64_1903_V1.exe

chaupad

@architect23 Can you send me your Windows_MediaFeaturePack_x64_1903_V1.exe
I was looking into https://support.microsoft.com/en-us/topic/media-feature-pack-list-for-windows-n-editions-c1c6fffa-d052-8338-7a79-a4bb980a700a

But still can not find suitable package. They are all saying that "can not update package to your windows"....

BTW
my environments is :
Qt 5.15.2
MSVC 2019 64 bit
Windows 10 Pro N

And I'm using MediaPlayer to play RTSP / HTTP videos
