導出視頻處理視頻小程序

Question

當我嘗試導出處理視頻以在瀏覽器中工作的處理小程序時，我遇到了一個經常性問題。這是一個簡單的應用程序，用於停止，播放和暫停.mp4視頻。當我使用Processing IDE運行它時，它工作得很好。但在執行的時候我出口產生的index.html，視頻框變空，沒有什麼發生，我在控制檯收到此錯誤：

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) 

也許這是一個已知的問題，但我仍然無法找到解決方案：

這是代碼：

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())); 
    } 
}
