Save Processing screen as video with jCodec – new

It may not be easy for readers to get the old jcodec-0.1.5.jar for what I have done in the last post. I tried to work out for a newer solution but found that the latest version did change quite a lot. The latest jcodec source is 0.2.0. I built the latest two files for the Processing test

  • jcodec-0.2.0.jar
  • jcodec-javase-0.2.0.jar

You can download a compressed file of the code folder where you can drop and extract inside the Processing sketch folder. The Processing codes also change to reflect the class structure. Here it is.
 

// Save video file
import processing.video.*;
import org.jcodec.api.awt.AWTSequenceEncoder8Bit;
 
import java.awt.image.BufferedImage;
import java.io.File;

import org.slf4j.LoggerFactory;
import org.apache.log4j.BasicConfigurator;
 
static Logger log;
Capture cap;
AWTSequenceEncoder8Bit enc;
String videoName;
String audioName;
boolean recording;
 
void setup() {
  size(640, 480);
  background(0);
  log = LoggerFactory.getLogger(this.getClass());
  BasicConfigurator.configure();
  cap = new Capture(this, width, height);
  videoName = "bear.mp4";
  recording = false;
  int fRate = 25;
  frameRate(fRate);
  cap.start();
  try {
    enc = AWTSequenceEncoder8Bit.createSequenceEncoder8Bit(new File(dataPath(videoName)), fRate);
  } 
  catch (IOException e) {
    e.printStackTrace();
  }
}
 
void draw() {
  image(cap, 0, 0);
  if (recording) {
    BufferedImage bi = (BufferedImage) cap.getNative();
    try {
      enc.encodeImage(bi);
    } 
    catch (IOException e) {
      e.printStackTrace();
    }
  }
}
 
void captureEvent(Capture c) {
  c.read();
}
 
void mousePressed() {
  recording = !recording;
  log.info("Recording : " + recording);
}
 
void keyPressed() {
  if (keyCode == 32) {
    try {
      enc.finish();
    } 
    catch (IOException e) {
      e.printStackTrace();
    }
  }
}
