JavaFX视频无法播放

我遵循了一些关于将 JavaFX与Swing(JFrame)结合起来播放视频的教程,但我得到的只是一个黑屏,其中视频应该没有任何实际内容播放,也没有报告任何错误.

我在这里做错了什么,为什么视频不播放？

我尝试了几个.flv视频,其中没有一个会开始播放(当我在浏览器中打开它们时它们会播放)

我在安装了K-lite完整编解码器包的Windows 8.1 N Pro上运行jre7和jdk1.7.0_45

编辑：更新我的代码后jewelsea的评论,没有任何改变,黑盒仍然出现没有内容播放,控制台没有显示任何文字出现

解决方法

我不能说100％确认原因是没有安装WMP,因为媒体功能包可能已经安装了其他解决了我的问题的东西,但问题解决了:)

我要感谢其他尝试的答案,我真的很感激.
