Is it possible to play video without crashing?
Dec 23rd, 2009, 10:33pm  

Hi, I have a simple program that plays a sequence of videos. On every OS I've tried, it consumes more and more memory until it finally runs out and the operating system kills the Processing application. I've tried it on Windows and MacOSX. Here is the program. I tried sprinkling explicit System.gc() calls throughout the code, but that doesn't help. Am I doing something wrong?

import processing.video.*;

Movie movie;
String movieFileName =
"/Users/stein/Documents/Processing/summer05/Clips/MVI_1626.AVI";

void setup() {
size(320, 240, P2D);
movie = new Movie(this, movieFileName);
movie.play();
movie.speed(16.0);
}

void draw() {
if (movie.duration() == movie.time()) {
  movie.stop();
  movie = new Movie(this, movieFileName);
  movie.play();
  movie.speed(16.0);
}
image(movie, 0, 0);
}

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

why do you create all these movies in draw? are you trying to loop?
if so, you better do it with loop();

probably solves your problem.

I don't want to loop the same movie over and over. I just do that in the code here to make the example that triggers the bug smaller. Really, I play a different movie every time. So loop() doesn't solve the problem.

thanks for the report. i should note that we won't be fixing any more bugs in the video library, as quicktime for java is no longer supported by
apple. we'll be switching to a new version of the video library based on
gsvideo in the future, i recommend trying that out for the time being:
