processing about video playing and reverse playing issue

[yoongangmin]

If run the code below, the video plays fine at first. If press the keyboard '2', it plays in reverse, and if press the keyboard '1', it plays. However, when I press '1' after press '2', the video runs a little and then stops :( what is the problem?

codes

import processing.video.*;

Movie myMovie; float playSpeed = 1.0;

void setup() { size(1920, 1080); frameRate(60); myMovie = new Movie(this, "test.mp4"); myMovie.play(); }

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

void draw() { background(0); image(myMovie, 0,0, width, height); myMovie.speed(playSpeed);

if(myMovie.time() > myMovie.duration()){ myMovie.stop(); myMovie.jump(myMovie.duration()); myMovie.stop(); } if(myMovie.time() < 0){ myMovie.jump(0); myMovie.stop(); } }

void keyPressed(){ if (key == '1'){ // keyPressed 1 = play playSpeed = 1.0; myMovie.play(); }

if (key == '2'){ // keyPressed 2 = playback playSpeed = -1.0; myMovie.play(); } }
