		video.setSize(new VideoSize(400, 300));
		EncodingAttributes attrs = new EncodingAttributes();
		attrs.setFormat("flv");
		attrs.setAudioAttributes(audio);
		attrs.setVideoAttributes(video);
		Encoder encoder = new Encoder();
		try {
			encoder.encode(source, target, attrs);
		} catch (Exception e) {
			// TODO Auto-generated catch block
			System.out.println("Exception:" + e);
			e.printStackTrace();
