我想将在线流保存到文件中，我在 java 中使用了 IMediaReader 和 IMediaWriter（在 PC 中），它可以正常读写，但是当我尝试在 android 中使用它时，会出现 ExceptionInInitializeError。这是我的代码

        IMediaReader reader = ToolFactory.makeReader("rtsp://217.115.145.185:1935/live/mp4:alexlivestream_2");
        IMediaWriter writer = ToolFactory.makeWriter("output.mp4", reader);

        // add a debug listener to the writer to see media writer events
       writer.addListener(ToolFactory.makeDebugListener());
       reader.addListener(writer);

        // read and decode packets from the source file and
        // and dispatch decoded audio and video to the writer
       int i=0;
        while (i++<1000) {
            System.out.println(i);
            if (reader.readPacket() != null) {
                break;
            }
        }
        writer.close();

例外：

没有 xuggler 的本地端口到 android 准备就绪。

Xuggler 基于 ffmpeg，这里有一个关于可用端口的讨论，这是一个起点：FFmpeg on Android
