 step01:用processing播放影片

程式碼如下:

import processing.video.*;

Movie movie;

void setup(){

  size(640,480);

  movie = new Movie(this,"launch2.mp4");

  movie.loop();

}

void draw(){

  image(movie,0,0);

}

void movieEvent(Movie m){

  m.read();

}

Step:02使用Processing 開啟視訊鏡頭

程式碼如下:

import processing.video.*;

Capture cam;

void setup(){

  size(640,480);

  cam=new Capture(this,640,480);

  cam.start();

}

void draw(){

  if(cam.available()){

    cam.read();

  }

  image(cam,0,0);

}

Step03:將視訊畫面變成影格，只要在image(cam0,0);下方加上saveFrame();

Step03-2:把mov檔案用Processing轉成影片檔播放

程式碼如下:

import processing.video.*;

Movie movie;

void setup(){

  size(640,480);

  movie = new Movie(this,"123.mov");

  movie.loop();

}

void draw(){

  image(movie,0,0);

}

void movieEvent(Movie m){

  m.read();

}

課堂作業二

Step01:屬標點及後即可變顏色

程式碼如下:

void setup(){

  size(640,480);

  background(255,0,0);

}

void draw(){

  println(frameCount);

}

void mousePressed(){

  loadPixels();

  for(int i=0;i<640*480/2;i++){

    pixels[i]=color(0,255,0);

  }

  updatePixels();

  saveFrame();

}

Step02:將一張照片變成很多種顏色。

程式碼如下:

void setup(){

  size(640,480);

  background(255,0,0);

}

void draw(){

  println(frameCount);

}

void mousePressed(){

  loadPixels();

  for(int i=0;i<640*480/2;i++){

    pixels[i]=color(0,255,0);

  }

  updatePixels();

  saveFrame();

}

Step03:將mov檔案的照片變成萬聖節顏色。

程式碼如下:

import processing.video.*;

Movie movie;

color []c={#F0F0F0,#FFF160,#FFC501,#FE9600,#03001C};

int now=0;

void setup(){

  size (640,480);

  background(#F0F0F0);

  movie = new Movie(this,"123.mov");

  movie.play();

}

void draw(){

  if(movie.available()){

  movie.read();

  image(movie,0,0);

  }

}

void mousePressed(){

  movie.pause();

  loadPixels();

  for(int i=0;i<640*480;i++){

    float bright = brightness(pixels[i]);

    int now = 4-int(bright/67);

    pixels[i] = c[now];

  }

  

  updatePixels();

}
