Java Swing视频播放器

我需要一个Java视频播放器，它在启动时打开文件浏览器，然后在Swing/Gui窗口中打开选定的视频文件。我已经找过了，但找不到有效的。我确实找到了一些类似于这里发布的代码，但我无法启动它，因为它说播放器无法解析为类型，它无法识别ControllerListener等等。。。如果我能得到一个简单的视频播放器的源代码或一些帮助，我将非常感谢

您可以使用Java Media Framework，在该框架中，您可以打开并播放导入项目中所需的视频。看一看api，你会发现你缺少的类和接口1）为了更快地获得更好的帮助，发布一个或。上面的示例既不定义也不导入

Player

或

Manager

类。2） “我已经搜索了allot，但找不到一个可用的。”有许多基于Swing的视频API。列出你找到的那些，并具体说明为什么它们不适合你。这样做有助于人们帮助你！3） 但最近，我推荐使用基于JavaFX的播放器。我在播放音频文件（音乐）方面有很好的经验。
