  • 0

I am using the MediaInfo.java class which can be found on sub4me to extract meta data from various video file formats. However I get the above error at run time.

This is an extract of my code, the exception is thrown at MediaInfo info = new MediaInfo()

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);

    According to this answer, the class MediaInfo is just JNI wrapper, so you need to download MediaInfo distribution to according platform and add those native library files to class path of your project..
