Hello.

Would it be possible, to convert audio/video files into binary code - in real time?

If yes, could you give me a hint or two?

Best regards

Hello there.

I'm using processing to track a color by clicking on a video image. I want to get some numbers send to MAX/MSP, so I can map the numbers to do certain things to a music sample.

I succeeded in connecting Processing to MAX/MSP, but I can figure out how to get Processing to send a float of numbers to MAX/MSP

I'm using this code in Processing:

import processing.video.*;
import maxlink.*;
// Variable for capture device
Capture video;

// A variable for the color we are searching for.
color trackColor;

MaxLink link = new MaxLink(this, "videotest"); // ** added for MaxLink

void setup() {
  size(320,240);
  video = new Capture(this,width,height,15);
  // Start off tracking for red
  trackColor = color(255,0,0);
  smooth();
}

void draw() {
  // Capture and display the video
  if (video.available()) {
    video.read();
  }
  video.loadPixels();
  image(video,0,0);

  // Before we begin searching, the "world record" for closest color is set to a high number that is easy for the first pixel to beat.
  float worldRecord = 500;

  // XY coordinate of closest color
  int closestX = 0;
  int closestY = 0;

  // Begin loop to walk through every pixel
  for (int x = 0; x < video.width; x ++ ) {
    for (int y = 0; y < video.height; y ++ ) {
      int loc = x + y*video.width;
      // What is current color
      color currentColor = video.pixels[loc];
      float r1 = red(currentColor);
      float g1 = green(currentColor);
      float b1 = blue(currentColor);
      float r2 = red(trackColor);
      float g2 = green(trackColor);
      float b2 = blue(trackColor);

      // Using euclidean distance to compare colors
      float d = dist(r1,g1,b1,r2,g2,b2); // We are using the dist( ) function to compare the current color with the color we are tracking.

      // If current color is more similar to tracked color than
      // closest color, save current location and current difference
      if (d < worldRecord) {
        worldRecord = d;
        closestX = x;
        closestY = y;
      }
    }
  }

  // We only consider the color found if its color distance is less than 10.
  // This threshold of 10 is arbitrary and you can adjust this number depending on how accurate you require the tracking to be.
  if (worldRecord < 10) {
    // Draw a circle at the tracked pixel
    fill(trackColor);
    strokeWeight(4.0);
    stroke(0);
    ellipse(closestX,closestY,16,16);
  }
}

void mousePressed() {
  // Save color where the mouse is clicked in trackColor variable
  int loc = mouseX + mouseY*video.width;
  trackColor = video.pixels[loc];
}


Thank you for your help!
