Video playback issue on STM32MP2

I'm reaching out regarding an issue I encountered while trying to play an MP4 video (x-h264 encoded) on the STM32MP2 board using QML. I used the qmlvideo example from Qt (reference: Qt Multimedia Video QMLVideo Example). While it works fine on my PC, the following errors appear when I run it on the MP2 (also attached file log.txt):

I also tested playing the video directly on the board with gst-play-1.0, and it worked without issues, confirming that the board has the necessary codec.

Thank you for your time and support!
