只是JNI包装器，所以您需要将发行版下载到相应的平台，并将这些本机库文件添加到项目的类路径中

String fileName = "file:///homes/sa303/NetBeansProjects/MoviePlayer1/src/Trailer/IronMan3.mp4";
File file1 = new File(fileName);
System.out.println(file1.getPath());

MediaInfo info = new MediaInfo();
info.open(file1);

String format = info.get(MediaInfo2.StreamKind.Video, 1, "Format", MediaInfo2.InfoKind.Text, MediaInfo2.InfoKind.Name);
String bitRate = info.get(MediaInfo2.StreamKind.Video, 1, "BitRate", MediaInfo2.InfoKind.Text, MediaInfo2.InfoKind.Name);
String frameRate = info.get(MediaInfo2.StreamKind.Video, 1, "FrameRate", MediaInfo2.InfoKind.Text, MediaInfo2.InfoKind.Name);
String width = info.get(MediaInfo2.StreamKind.Video, 1, "Width", MediaInfo2.InfoKind.Text, MediaInfo2.InfoKind.Name);

String audioBitrate = info.get(MediaInfo2.StreamKind.Audio, 1, "BitRate", MediaInfo2.InfoKind.Text, MediaInfo2.InfoKind.Name);
String audioChannels = info.get(MediaInfo2.StreamKind.Audio, 1, "Channels", MediaInfo2.InfoKind.Text, MediaInfo2.InfoKind.Name);
