QT + Android - Error - MediaPlayerNative: Unable to create media player

I'm doing a simple test to play a video using QML with Android.

The app works like this:

1. Click in the choose button.
2. Select a video in the dialog. obs: A video file already in phone's storage, no download required
3. Play the video.

This works perfectly for Desktop.

When I do the same for Android I can go until the 2nd step. When I select the video I can read this error in Application Output:

E MediaPlayerNative: Unable to create media player
D Qt MediaPlayer: setDataSource failed.: status=0x80000000
V MediaPlayer: resetDrmState:  mDrmInfo=null mDrmProvisioningThread=null mPrepareDrmInProgress=false mActiveDrmScheme=false
V MediaPlayer: cleanDrmObj: mDrmObj=null mDrmSessionId=null
V MediaPlayer: resetDrmState:  mDrmInfo=null mDrmProvisioningThread=null mPrepareDrmInProgress=false mActiveDrmScheme=false
V MediaPlayer: cleanDrmObj: mDrmObj=null mDrmSessionId=null
W libEGL  : EGLNativeWindowType 0x700fb22010 disconnect failed

Its clear that the code can't create a MediaPlayer.

Here a link to my test code in my github: https://github.com/Oshio09/QML-Video-Test

What should I change to make the media player reproduce the video at Android?
