Reference

JAVE (Java Audio Video Encoder) is an open source Java library that allows converting audio or video to different formats. For example, it helps you convert audio or video to MP3 format.

Essentially, JAVE is a wrapper that calls FFMPEG commands to perform format conversion.

FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. No matter if they were designed by some standards committee, the community or a corporation.
FFmpeg is highly portable, it can be compiled and run on most operating systems such as Linux, Mac OS X, Microsoft Windows, BSD, Solaris, etc.
Introduction to FFMpeg

In this article, I will show you how to use Java JAVE to convert any video or audio to MP3 format.

2. Examples

libmp3lame is an MP3 library included in the FFmpeg project, used to convert any video or audio format to MP3 format.

ConvertToMp3.java

package org.o7planning.java_14173_mp3;

import java.io.File;

import ws.schild.jave.Encoder;
import ws.schild.jave.MultimediaObject;
import ws.schild.jave.encode.AudioAttributes;
import ws.schild.jave.encode.EncodingAttributes; 

// Convert any video (or audio) to MP3.
public class ConvertToMp3 {

	private static void convertToMP3(File source, File target) throws Exception {
		// Audio Attributes
		AudioAttributes audio = new AudioAttributes();
		audio.setCodec("libmp3lame");
		audio.setBitRate(128000);
		audio.setChannels(2);
		audio.setSamplingRate(44100);

		// Encoding attributes
		EncodingAttributes attrs = new EncodingAttributes();
		attrs.setOutputFormat("mp3");
		attrs.setAudioAttributes(audio);

		// Encode
		Encoder encoder = new Encoder();
		encoder.encode(new MultimediaObject(source), target, attrs);
	}

	public static void main(String[] args) throws Exception {
		File wavFile = new File("/Volumes/New/Test/wavFile.wav");
		File outputMp3File = new File("/Volumes/New/Test/output/outputFile.mp3");

		convertToMP3(wavFile, outputMp3File);
		System.out.println("Done!");
	}
}

Next is an advanced example, converting an MP4 video to MP3 with status information during conversion, this way you can observe the percentage of work that has been completed.

AdvancedExample.java

package org.o7planning.java_14173_mp3;

import java.io.File;

import ws.schild.jave.Encoder;
import ws.schild.jave.MultimediaObject;
import ws.schild.jave.encode.AudioAttributes;
import ws.schild.jave.encode.EncodingAttributes;
import ws.schild.jave.info.MultimediaInfo;
import ws.schild.jave.progress.EncoderProgressListener;

public class AdvancedExample {

	private static void convertToMP3(File source, File target, //
			EncoderProgressListener listener) throws Exception {
		// Audio Attributes
		AudioAttributes audio = new AudioAttributes();
		audio.setCodec("libmp3lame");
		audio.setBitRate(128000);
		audio.setChannels(2);
		audio.setSamplingRate(44100);

		// Encoding attributes
		EncodingAttributes attrs = new EncodingAttributes();
		attrs.setOutputFormat("mp3");
		attrs.setAudioAttributes(audio);

		// Encode
		Encoder encoder = new Encoder();
		encoder.encode(new MultimediaObject(source), target, attrs, listener);
	}

	public static void main(String[] args) throws Exception {
		Runnable runnable = new Runnable() {
			public void run() {
				// Video File:
				File wavFile = new File("/Volumes/New/Test/sample-16m.mp4");

				File outputFile = new File("/Volumes/New/Test/output/output2.mp3");

				EncoderProgressListener listener = new ConvertProgressListener();
				try {
					convertToMP3(wavFile, outputFile, listener);
				} catch (Exception e) {
					System.err.println("Error: " + e);
				}
				System.out.println("Done!");
			}
		};
		Thread thread = new Thread(runnable);
		thread.start();
	}
}

class ConvertProgressListener implements EncoderProgressListener {

	public ConvertProgressListener() {
	}

	public void message(String m) {
		System.out.println("Message: " + m);
	}

	public void progress(int p) {
		// Find %100 progress
		double progress = p / 1000.00;
		System.out.println(progress);
	}

	public void sourceInfo(MultimediaInfo m) {
		int videoHeight = m.getVideo().getSize().getHeight();
		int videoWidth = m.getVideo().getSize().getWidth();
		System.out.println("Video Size: " + videoWidth + "/" + videoHeight);
		long duration = m.getDuration();
		System.out.println("Duration: " + duration + " milliseconds");
	}
}

Output:

Video Size: 1280/720
Duration: 997880 milliseconds

		String[] supportedEncodingFormats = encoder.getSupportedEncodingFormats();
		System.out.println("\n\n=== Supported Encoding Formats: ====================\n");
		print(supportedEncodingFormats);
		// 3dostr   4xm   aa   aac   aax   ac3 ...  
		String[] supportedDecodingFormats = encoder.getSupportedDecodingFormats();
		System.out.println("\n\n=== Supported Decoding Formats: ====================\n");
		print(supportedDecodingFormats);
	}

	private static void print(String[] array) {
		int i = 0;
		for (String s : array) {
			i++;
			System.out.print(s + "   ");
			if (i % 6 == 0) {
				System.out.println();
			}
		}
	}

	public static void main(String[] args) throws EncoderException {
		showEncodersDecoders();
		showSupportedFormats();
	}
