[VLCJ使用getClass（）。getResource（）时不播放视频

Question

我正在制作游戏，但这取决于视频；我以前没看过视频，所以我使用VLCJ，因为这是YouTube上出现的第一件事。无论如何，问题是当我使用getClass().getResource()并执行jar时，它不会加载媒体。因此，我需要的是可以从广口瓶中打开媒体。

String path1 = getClass().getResource("/media/introVideo.mp4").getFile(); //Not works (I want this to work)

String path2 = getClass().getResource("/media/introVideo.mp4").toExternalForm());  //Not works (I want this to work)

String path3 = getClass().getResource("/media/introVideo.mp4").toString());  //Not works (I want this to work)

String path4 = getClass().getResource("/media/introVideo.mp4").getFile().replace("/", "\\"); //Works (Not what I need)

String path5 = new File("src\\media\\introVideo.mp4").toString(); //Works (Not what I need)

使用path1，path2和path3时出现的错误如下：

libdvdnav: Using dvdnav version 6.0.0
libdvdread: Could not open D:\Programming\HyperDance\\D:\Programming\HyperDance\build\classes\media\introVideo.mp4 with libdvdcss.

            emp.prepareMedia(new Object().getClass().getResource("/media/introVideo.mp4").getFile());

总结：

• 我需要从罐子中播放视频。

• 当我不使用getClass().getResource()时播放视频，但是我需要使用它来从jar中访问媒体。

• 问题：如何使用VLCJ从罐子中播放视频？

Answer 1

嗯，我已经找到了解决方法：

• 首先，将jar放在另一个包含视频的文件夹的Surprise文件夹中。

• 然后，我让程序搜索jar内的文本文件guide.txt以了解我的Surprise文件夹的位置。

• 最后，我用视频的路径替换了guide.txt路径：

  C：/ Users / Steve / Desktop / Surprise / HyperDance-BTS.jar！ /media/guide.txt

  -> C：/用户/史蒂夫/桌面/惊喜/ 视频 /introVideo.mp4

文件夹：

• 惊喜（C：，D ：，无论是光盘：）
  • HyperDance-AC / DC.jar
    • Guide.txt
    • 媒体（图像和声音）
  • 视频（隐藏文件夹）
    • introVideo.mp4

        String url = mrl.replace("/", "\\").split("\\\\",2)[1].split("Surprise")[0].concat("Surprise\\videos\\"+video);
          return url;
    }
}

是否有更好的方法或更正式的方法？
