javafx mediaview white flash on transition

问题

Folks...

I'm using the following code to transition between two videos.

public void loadMedia(Media media)
{
    MediaPlayer newPlayer = new MediaPlayer(media);
    newPlayer.setAutoPlay(true);
    mediaView.setMediaPlayer(newPlayer);
    player = newPlayer;
}

When I call loadMedia with the new video, the mediaplayer flashes white briefly. I'm guessing this has to do with the status taking time. But I need these transitions to go smoothly with no flash.

What to do?

Thanks, GeePaw

As so often, I answered my own question shortly after. The trick is to wait for the status to be ready before you change the view's player:

public void loadMedia(Media media)
{
    MediaPlayer newPlayer = new MediaPlayer(media);
    newPlayer.setAutoPlay(true);
    newPlayer.setOnReady(()->videoReady(newPlayer));
}

private void videoReady(MediaPlayer newPlayer)
{
    mediaView.setMediaPlayer(newPlayer);
    player = newPlayer;
}
