可以用javafx媒體播放mp4 formet視頻文件嗎？

我正在嘗試使用javafx媒體播放視頻。但我無法在本地機器視頻中播放視頻。我嘗試使用默認的AdvancedMedia.java文件javafx Ensemble.jar文件。我複製了相同的文件代碼並粘貼在我的日食中。在那也玩幾秒鐘和彎腰。幾秒鐘。但不是默認的媒體文件位置，如果我給我的本地機器中的任何.mp4格式的文件，它不會播放，也不會給出錯誤。請幫我解決這個問題。我按下面的代碼可以用javafx媒體播放mp4 formet視頻文件嗎？

來播放本地視頻使用以下

private static File file = new File("d:/videos/xyz.mp4"); 
private static final String MEDIA_URL = file.toURI().toString();

這對我的作品。希望這會幫助你。
