No video render on Raspberry 4

SteMMo

Hi all,
i wrote a simple app with a qml 'Video' component.
I developed and compiled it on Windows for Windows by QtCreator to loop mp4 videos and jpg images.
I copied the project on Raspberry 4 (Qt5.11), I compiled it and run it.
After the first runs I added some modules cause I had some errors/warning.
Now I have no errors or warnings, the application starts but it is not able to render the first mp4 video.
I'm checking the modules and libs but the video is not rendered.
Any idea?
Thanks, regards

Update

jpgs and webm files are rendered.
Not able to render mp4 files.

Hi,

Are you sure you installed all the needed codecs ?

SteMMo

No, I'm not sure .. which packages are needed for mp4 support?

I'd install all of the GStreamer plugin packages.
