I tried using ML MediaPlayer by exporting it as Unity package from ML Exampes and making it work with ML Simulator. Everything seems to work (I can activate the slider and press the buttons with the controller) but the video doesn't activate, and I get these errors: Error: MLMediaPlayerCreate in the Magic Leap API failed.

Hi @PPXR, Welcome to the Magic Leap 2 Developer Forums. We are very grateful to have you here engaging with us. At this time, the MLMediaPlayer is not supported in editor / app sim. We will certainly inform you of any developments in the future, though. Best, El
