导出视频处理视频小程序

Question

当我尝试导出处理视频以在浏览器中工作的处理小程序时，我遇到了一个经常性问题。这是一个简单的应用程序，用于停止，播放和暂停.mp4视频。当我使用Processing IDE运行它时，它工作得很好。但在执行的时候我出口产生的index.html，视频框变空，没有什么发生，我在控制台收到此错误：

Exception in thread "Animation Thread" java.lang.NoClassDefFoundError: Could not initialize class quicktime.QTSession 
    at processing.video.Movie.init(Unknown Source) 
    at processing.video.Movie.<init>(Unknown Source) 
    at processing.video.Movie.<init>(Unknown Source) 
    at sketch_nov14a.setup(sketch_nov14a.java:31) 
    at processing.core.PApplet.handleDraw(Unknown Source) 
    at processing.core.PApplet.run(Unknown Source) 
    at java.lang.Thread.run(Unknown Source) 

也许这是一个已知的问题，但我仍然无法找到解决方案：

这是代码：

import processing.video.*; 

Movie theMov; 
boolean isPlaying; 
boolean isLooping; 


void setup() { 
    size(600,400,P2D); 
    theMov = new Movie(this, "http://www.sinopsedofilme.com.br/processing/video2.mp4"); 
    /* only use 1 of the following options */ 
    theMov.play(); //plays the movie once 
    theMov.loop(); //plays the movie over and over 
    isPlaying = true; 
    isLooping = true; 

} 

void draw() { 
    image(theMov, 0,0); 
} 

void movieEvent(Movie m) { 
    m.read(); 
} 

void keyPressed() { 
    if (key == 'p') { 
    // toggle pausing 
    if (isPlaying) { 
     theMov.pause(); 
    } else { 
     theMov.play(); 
    } 
    isPlaying = !isPlaying; 

    } else if (key == 'l') { 
    // toggle looping 
    if (isLooping) { 
     theMov.noLoop(); 
    } else { 
     theMov.loop(); 
    } 
    isLooping = !isLooping; 

    } else if (key == 's') { 
    // stop playing 
    theMov.stop(); 
    isPlaying = false; 

    } else if (key == 'j') { 
    // jump to a random time 
    theMov.jump(random(theMov.duration())); 
    } 
}
