B4J Question remove node or re-initialize ?

[Olivier Zeegers]

Hi,

I create a mediaplayer in runtime via this code:

Private m As MediaPlayer
Private mv As JavaObject

    m.Initialize("m",File.GetUri("D:\Kiwanis\2018-2019\Sportcommissie\DonkerRun\Rode Knop","effect5.mp4"))
    mv.InitializeNewInstance("javafx.scene.media.MediaView",Array(m))
    MainForm.RootPane.AddNode(mv,0,0,1000,1000)
    mv.RunMethod("toBack",Null)

this creates a video that plays in the background when i call m.Play

Now, every now and then I want to play a different video....

When I re-initialize the mediaplayer object with the same code but a different filename nothing happens.
When I try to create another mediaplayer I cannot view the video probably because the first video is projecting over it ?
When I try to remove the node in runtime I have to give an index of which node to remove ?

Any suggestions ?

thank you

Dim MediaViewNode As Node = mv

MediaViewNode.RemoveNodeFromParent

is there a way to preload these video files instead of constantly loading them from disk ? I would like to play different videos randomly. And provide an .exe file that contains all media files..

You can reuse the same MediaView and call mv.RunMethod("setMediaPlayer", Array(NewMediaPlayer)) to replace the media player. I don't think that it will make any practical difference.

Is there an event that is called when mediaplayer ends playing the video file ?

I play the video in the background while the user still can interact with the interface and want to play a new video when the old video is finished.

thank you

yes. See the documentation.
