B4X: 
Dim mp As MediaPlayer
Dim jo,mv As JavaObject
mp.Initialize("mp",File.geturi(File.DirApp,"swgames.mp4"))
mv=jo.InitializeNewInstance("javafx.scene.media.MediaView",Array As Object(mp))
B4XPages.GetNativeParent(Me).RootPane.AddNode(mv,0,0,Root.Width,Root.Height)
mp.Play

what am I doing wrong ?
