如何在javafx中从FileChooser播放视频 [英] how I can play an video from FileChooser in javafx

问题描述

希望您能帮助我解决此问题，我尝试在所有程序中通过类似选项文件的 Button Open 来使此代码用于播放视频.不行我不知道怎么了.

I hope you to help me to resolve this problem , I try make this code for play video from an Button Open like option file in all the program but it doesn't work. I don't know what's wrong.

这是我的代码:

btn.setOnAction(new EventHandler<ActionEvent>() {

        @Override
        public void handle(ActionEvent event) {
            FileChooser chooser = new FileChooser();
            FileChooser.ExtensionFilter filter = new FileChooser.ExtensionFilter("select your media(*.mp4)", "*.mp4");
            chooser.getExtensionFilters().add(filter);
            File file = chooser.showOpenDialog(primaryStage);
            if ( file !=null){

                Media source = new Media(file.getPath());
                MediaPlayer player = new MediaPlayer(source);
                MediaView view = new MediaView(player);
                root.getChildren().add(view);
                player.play();


            }
             else {
                label.setText("vide ");
            }

推荐答案

您将路径传递到

You pass the path to the constructor of Media. This constructor expects a URI string however. Fortunately File can be converted to URI using toURI:

Media source = new Media(file.toURI().toString());
