QML Video not working on Android and makes UI invisible

When the attached application runs on Android (LG G8, Android 9, NVIDIA Shield, or Android Emulator), the video does not display although audio does play back. While playing, the entire application shows up as the background color. If one knows where the "play/pause" button is, one can pause the video and have the UI reappear, only to disappear again when play is clicked.

Using the Android emulator with either an Android 9 or Q "Android TV" emulator causes the GPU fan to run full speed and the machine to lock-up until the emultor is interrupted or killed.

With versions of Qt older that 5.14.0, e.g. 5.13.2, the application displays video correctly and the UI remains functional and visible, as expected.

The code is at https://github.com/NielsMayer/qmlvideo

This code also demonstrates a separate minor problem, in that on Linux Desktop platform, the 'metaData' property on the QML Video item is filled, displaying information on the video in the center of the footer. On Android (both for 5.14 and older) this 'MediaPlayer.metaData' property for the QML Video item is not filled; thus, "Loading Video" remains displayed even after the video is playing. The associated code is https://github.com/NielsMayer/qmlvideo/blob/af0c05229c3f4cb9b8b58dccaac5281dcda5cb30/main.qml#L83 .... Should I file a separate bug, or did I miss somewhere that 'metaData' is platform specific?
