QMediaplayer plugin - no service found for - "org.qt-project.qt.mediaplayer"
-
Hello everyone,
First of, I am using latest Qt 5.12.3 with x64 msvc-2017 (visual studio) on my windows 10 computer.
I have recently started working on a personal project involving a video player. But I've quickly met an issue that's been eating at me for days :
Just when I call the constructor for QMediaPlayer, my debug terminal goes bananas and throws the following :

defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"I've spent days looking for a solution, tried rebuilding Qt, tried using another version of Qt, and/or versions of MSVC... Nothing changes, I can't get this service to work.
Any insight ? Hope someone can help me out I'm starting to run out of ideas.
Thanks a lot in advance, looking forward to reading from you guys.

Hello aha_1980,
First of, thanks a lot for taking the time to reply.
I have checked my paths and PATH environment variable, but it seems like the same path is used everywhere. Although... it also seems both DEBUG and RELEASE plugin DLLs are being loaded.
I don't suppose that's normal, is it ? Is there something I can do about that ?Thanks in advance.
Best regards,
TomHat -
Hi
There might be an app installed that added something to the PATH environment so
its Qt dlls are found first.
You have to look PATH over and try to see if any points to program folder or the like. -
Hello,
Thank you as well for the help. I have now looked into my PATH environment variables. Nothing shocking there... I have searched for all QT resources used in other softwares I have installed on my computer, and deleted them all.
Nothing changed.I aslo tried compiling a debug-only version of Qt, and here's what I get...

Hi
I wonder if something up with your DirectX.
Can you try to run dxdiag.exe
and see if all looks good ?
-
Hi
Could try to see if a new driver is available for your intel card ?
its worth a shot -
Actually, after some more research, turned out @mrjj wasn't too far from fixing my problem. I just needed to google "missing media service windows 10", and learned some computers needed to manually download media update from microsoft's website.
Well that only solved half of the problem, as I still have no sound coming out, and I get the following error message after creating a QMediaPlaylist :Invalid parameter passed to C runtime function.
Invalid parameter passed to C runtime function.
Invalid parameter passed to C runtime function.
Invalid parameter passed to C runtime function.Thanks guys for you help !

Hi
Your DirectX looked pretty ok.
So not sure what it still is missing.
Did you look in dxdiag under sound ?
and it all looked fine ? -
Hey,
Sorry for late answer. Yes everything seemed fine. No error report at least.
But I'm guessing that this might not actually be linked with this topic anymore. So I'll just look into this issue on my own from there.Anyway, thanks a lot for the support !
Best regards,
TomHat
