Java JNI bindings for Whisper

This package provides Java JNI bindings for whisper.cpp. They have been tested on:

• Darwin (OS X) 12.6 on x64_64
• Ubuntu on x86_64
• Windows on x86_64

The "low level" bindings are in WhisperCppJnaLibrary. The most simple usage is as follows:

import io.github.ggerganov.whispercpp.WhisperCpp;

public class Example {

    public static void main(String[] args) {
        String modelpath;
        WhisperCpp whisper = new WhisperCpp();
        // By default, models are loaded from ~/.cache/whisper/ and are usually named "ggml-${name}.bin"
        // or you can provide the absolute path to the model file.
        whisper.initContext("base.en"); 
        
        long context = whisper.initContext(modelpath);
        try {
            whisper.fullTranscribe(context, samples);
            
            int segmentCount = whisper.getTextSegmentCount(context);
            for (int i = 0; i < segmentCount; i++) {
                String text = whisper.getTextSegment(context, i);
                System.out.println(segment.getText());
            }
        } finally {
             whisper.freeContext(context);
        }
     }
}
