GSMovie cannot be inspected to tell if it's finished.

in Contributed Library Questions • 2 years ago

As far as I can see there's no functioning way to tell if a GSMovie has finished.

The scenario I have is that there is a video being painted as part of a processing sketch. When the video is finished, I would like to do something. However, there's no way I can find to get a GSMovie to tell me it's finished.

I've tried the following expressions and none of them ever return true. The video simply goes black and stops getting new frames. Really frustrating - been about 4 hours of work on this so far to fail to get a simple boolean value...

movie.frame() >= movie.length() - 1

movie.time() == movie.duration()

!movie.isPlaying();

!movie.isPlaying() && !movie.isPaused()

Compare the movie.time() and the movie.duration() using a tolerance threshold, i.e.:

import codeanticode.gsvideo.*;
GSMovie movie;
void setup() {
size(180, 120, P3D);
movie = new GSMovie(this, "station.mov");
movie.play();
}
void movieEvent(GSMovie myMovie) {
movie.read();
}
void draw() {
background(0);
if (movie.width > 1 && movie.height > 1) {
if (abs(movie.time() - movie.duration()) < 0.01) {
println("Reached the end");
}
image(movie, 0, 0);
}
}

On the other hand, the isPlaying() method should return the appropriate playing status. I'll look at this.

Ok, after a quick inspection of the code I found why the isPlaying() method doesn't return the correct playing status. This fix (among many others) will go into the next stable release of gsvideo, which I'll hopefully be able to put out soon.

For the time being use the abs() function with the tolerance threshold, as mentioned in the previous post.
