How can I extract Metadata from a .MP4 and a .AVI with native library in JAVA

Question

I try to make a media player and a video library for a school project, and I need to extract metadata from a .MP4 and .AVI to store in a XML files and can edit this metadata.

I did some research and I didn't find what I'm looking for, because I need a native Java library, and not a library that we need to install in our IDE.

And I have make my media player with JavaFX, and JavaFX can not read .avi media. So I need to convert this .avi to .mp4 is it possible to do this in Java with a native library?

*"I need a native java library, and not a library that we need to install in our IDE"* what do you mean? You mean something that is part of the standard library? — Federico klez Culloca, Apr 26 '22 at 07:18

I don't know I need to try, but I need to have the title, the autor,date and other basic information from a mp4 — Madarra, Apr 26 '22 at 07:30
I still don't understand your request for "a native library". You will most certainly not find that in the Java standard library. But so what. Nobody writes real-world software which is just based on the Java standard library. What's the problem with using some external library? — mipa, Apr 26 '22 at 09:29
it is a constraint to create my mediaplayer fix by my professor. Me too I don't understand why... — Madarra, Apr 26 '22 at 09:48
@Madarra Maybe your teacher wants you to use only the standard Java APIs instead of some third party APIs, is it what (s)he meant? — gouessej, Apr 26 '22 at 14:12
Yes its was that, I have asked him what a really want. Because i didn't really understand what's is the difference with standard Java APIs and third party APIs. Thanks for your response. — Madarra, Apr 26 '22 at 16:22

I'm not quite clear what is meant by "native java library". Java itself (JDK / JRE) does not support parsing of media meta data. The only possibility would be to use a third party library like "Apache Tika":

You can do this with the Java standard library.

public class YourClass {

    Path yourFile = ...;
    BasicFileAttributes attr = Files.readAttributes(yourFile, BasicFileAttributes.class);
    
    System.out.println("creationTime: " + attr.creationTime());
    System.out.println("lastAccessTime: " + attr.lastAccessTime());
    System.out.println("lastModifiedTime: " + attr.lastModifiedTime());
    
    System.out.println("isDirectory: " + attr.isDirectory());
    System.out.println("isOther: " + attr.isOther());
    System.out.println("isRegularFile: " + attr.isRegularFile());
    System.out.println("isSymbolicLink: " + attr.isSymbolicLink());
    System.out.println("size: " + attr.size());
}

This is platform dependent and may throw exceptions or return unexpected results.

Thanks for your response men. That's part of what I was looking for with more information. I will use "Apache Tika" for more information about .mp4 files. — Madarra, Apr 26 '22 at 16:24
