Play a YouTube video in JavaFX?

Question

Moderator action: deleted rant and cleaned up what remains.
I am trying to make this code play an FLV video, and it doesn't show any video. Only Music. How can I convert, for instance, a YouTube video, to play in JavaFX? If I download a YouTube video, how can i encode it?

Answer 1

After the question title has been cleaned up, I can see now that it relates to youtube video playback.
Just embed the youtube html5 video player in a webview and stream video from youtube.
This will work for videos that youtube has made compatible with their html5 player (about 30% it seems).
Here is a sample embedding a youtube hosted trailer uploaded by sony pictures.
import javafx.application.Application;
import javafx.scene.*;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
public class YouTubePlayer extends Application {
  public static void main(String[] args) throws Exception { launch(args); }
  @Override public void start(final Stage stage) throws Exception {
    final WebView webView = new WebView();
    webView.getEngine().loadContent(
      "<iframe width=\"640\" height=\"390\" src=\"http://www.youtube.com/embed/IyaFEBI_L24\" frameborder=\"0\" allowfullscreen></iframe>"
    stage.setScene(new Scene(webView, 660, 410));
    stage.show();
