pyside6-deploy - QtMultimedia

CKurdu

Hello,

I have an app with pyside6 and qml. This apps using qml multimedia features. When I run it from command below it works as expected.

python main.py

Then I deployed it by using pyside6-deploy. After I run the app, mediaplayer doesn't work. Also I am getting this output .

No QtMultimedia backends found. Only QMediaDevices, QAudioDevice, QSoundEffect, QAudioSink, and QAudioSource are available.

I have added the qt multimedia module to the pysidedeploy.spec file like below.

# qt modules used. comma separated
modules = QuickControls2,Gui,Network,Quick,Qml,Core,Multimedia

# qt plugins used by the application
plugins = qmltooling,platforms,tls,networkinformation,generic,platforms/darwin,accessiblebridge,iconengines,scenegraph,egldeviceintegrations,networkaccess,imageformats,platforminputcontexts,xcbglintegrations,platformthemes,mediaservice

Also, I have tried to add the QtMultimeda.pyd to tye pyside6 folder manually.
But it doesn't work also.

What is the problem here?

O.S. : windows 11.
pyside version: pyside 6.72 and pyside 8.1.1

CKurdu

solved the problem by adding multimedia to the plugins.

@CKurdu glad you found out and shared your findings.

Please mark the thread as solved so other forum users may know a solution has been found :-)

multimedia should have automically been added to the plugins by the tool itself (atleast in 6.8.1 as i check with an example). So, if anyone stumbles upon this, please use the latest version of PySide6 and check.
