Converting (resizing) video's in Java with Xuggler

Java


Last week, I had to investigate a case where we want to resize a video to a whole set of resized video's. So you have a source video with resolution: 1280x800 and I want a video for 640x400, 320x200, 160x100, ... etc, etc, ...

Of course, we need Java for this ;-) ! I came across this library http://www.xuggle.com/xuggler/. Xuggler is the easy way to uncompress, modify, and re-compress any media file (or stream) from Java.

Well, they say it is "easy", but for me it wasn't. This is my (finally!) working example.

Prerequisites

  • install Xuggler
  • set the following ENV vars

    • export XUGGLE_HOME="/usr/local/xuggler"
export PATH=$PATH:$XUGGLE_HOME/bin
export LD_LIBRARY_PATH="/usr/local/xuggler/lib"

Resizing a video

MediaConvertor

public class MediaConvertor {
	private static final Integer WIDTH = 640;
	private static final Integer HEIGHT = 360;
 
	private static final String INPUT_FILE = "/tmp/input.mp4";
	private static final String OUTPUT_FILE = "/tmp/output.mpg";
 
	public static void main(String[] args) {
		// create custom listeners
		MyVideoListener myVideoListener = new MyVideoListener(WIDTH, HEIGHT);
		Resizer resizer = new Resizer(WIDTH, HEIGHT);
 
		// reader
		IMediaReader reader = ToolFactory.makeReader(INPUT_FILE);
		reader.addListener(resizer);
 
		// writer
		IMediaWriter writer = ToolFactory.makeWriter(OUTPUT_FILE, reader);
		resizer.addListener(writer);
		writer.addListener(myVideoListener);
 
		// show video when encoding
		reader.addListener(ToolFactory.makeViewer(true));
 
		while (reader.readPacket() == null) { 
			// continue coding
		}
	}
}

Resizer

import com.xuggle.mediatool.MediaToolAdapter;
import com.xuggle.mediatool.event.IVideoPictureEvent;
import com.xuggle.mediatool.event.VideoPictureEvent;
import com.xuggle.xuggler.IVideoPicture;
import com.xuggle.xuggler.IVideoResampler;
 
public class Resizer extends MediaToolAdapter {
	private Integer width;
	private Integer height;
 
	private IVideoResampler videoResampler = null;
 
	public Resizer(Integer aWidth, Integer aHeight) {
		this.width = aWidth;
		this.height = aHeight;
	}
 
	@Override
	public void onVideoPicture(IVideoPictureEvent event) {
		IVideoPicture pic = event.getPicture();
		if (videoResampler == null) {
			videoResampler = IVideoResampler.make(width, height, pic.getPixelType(), pic.getWidth(), pic
					.getHeight(), pic.getPixelType());
		}
		IVideoPicture out = IVideoPicture.make(pic.getPixelType(), width, height);
		videoResampler.resample(out, pic);
 
		IVideoPictureEvent asc = new VideoPictureEvent(event.getSource(), out, event.getStreamIndex());
		super.onVideoPicture(asc);
		out.delete();
	}
}

MyVideoListener

import com.xuggle.mediatool.MediaToolAdapter;
import com.xuggle.mediatool.event.IAddStreamEvent;
import com.xuggle.xuggler.ICodec;
import com.xuggle.xuggler.IStreamCoder;
 
public class MyVideoListener extends MediaToolAdapter {
	private Integer width;
	private Integer height;
 
	public MyVideoListener(Integer aWidth, Integer aHeight) {
		this.width = aWidth;
		this.height = aHeight;
	}
 
	@Override
	public void onAddStream(IAddStreamEvent event) {
		int streamIndex = event.getStreamIndex();
		IStreamCoder streamCoder = event.getSource().getContainer().getStream(streamIndex).getStreamCoder();
		if (streamCoder.getCodecType() == ICodec.Type.CODEC_TYPE_AUDIO) {
		} else if (streamCoder.getCodecType() == ICodec.Type.CODEC_TYPE_VIDEO) {
			streamCoder.setWidth(width);
			streamCoder.setHeight(height);
		}
		super.onAddStream(event);
	}

Hello,

This is really a very good article. Thanks a lot..

Could u pls provide me the help for compressing vdo or changing bitrates of vdo. What i want to do is to reduce the vdo file size.

Hi,

If I resize a video to another of the same properties, the size is increased (double or even more size).

What may be the problem?

Thanks,
Luis

The article which you provided is very helpful for me. Is is possible to grasp the voice(audio) from a video lecture file and write the voice(professor's lecture) as text words in word document by using xuggler.

Hi mujafar,

I think it's possible to extract the audio from the video with Xuggler, but the translation of audio to text words will be difficult :-). I don't think Xuggler has a feature like that. You will need other software to do that.

Kind regards,
Jochen

Hello Sir Your Article is good and converting well also...
I need to add video codec in video
I tried to add in MyVideoListener
streamCoder.setCodecID(ICodec.ID.CODEC_ID_MPEG4);

But it doesn't work....would you please provide the solution....

Hi Suren,

Thank you for your message. Unfortunately, I don't know how to implement your feature request. Maybe try getting support by this link: http://www.xuggle.com/xuggler/support

Kind regards,

I have no idea ... sorry :-(

That was because a video with the same name existing.
Instead of replacing video, renaming with a new name solved the problem.
Many thanks...
