problem for read munch .mov videos

in Programming Questions • 2 years ago

Hello all, for a video projection work, i use different videos in a random order.
I made the programm, but it crashes in a random time. It appears that the cpu memory never refreshes, and it uses to continually grow up with the time, as the videos are loaded. My program is principaly like this : (I don't post the whole thing because i think the problem is a question of synthax into this lines)

import processing.opengl.*;

import processing.video.*;
(...)
Movie gif;

void setup() {
(...)
}

void draw() {

(...)

   (...)
           gif.play();
(...)
gif.stop();
gif=null;

Please, does somebody have an idea ?

Thank you.

Salut,

Whoa this is a strange syntax.
Why not just using string concatenation and load your Movie with something like :

gif = new Movie(this, "gif" + aleatoire + ".mov");

It'd just avoid all the unnecessary check on the aleatoire value.
But be careful to be sure that isn't under 0 or above 50 like :

if (aleatoire > 0 && aleatoire < 51) {
gif = new Movie(this, "gif" + aleatoire + ".mov");
}

If it's a significant video it might freeze your sketch (as your loading your video in draw()).
But they are libraries or techniques that could help for that.

If the video aren't too big, you could use a global array in which you load all your video in memory during setup() and then just read the one you want. Like :

Movie[] movies = new Movie[50];
void setup() {
size(...);
for (int i=0; i<movies.length; i++) {
movies[i] = new Movie(this, "gif" + aleatoire + ".mov");
}
}

thank you very much!!(ok I know my syntax is personnal...Im very newbie and attempt learn alone :)!)

okay but Ive 500Mo of video (ive not 50 but 140 video) it's for this I want to load one after one.

ive understand your synthax, but im newbie, and my "aleatoire" variable is a float... how make a int?

(i know maybe in the lesson Ive the answer, but I munch finish this work at 8:00 ...)

I Think a problem is when I rewitte on the same name the ".mov", he don't totaly clear the last, and the virtual memory upgrade!*

help! :)

To change aleatoire from float to int simply define it as an int.
At the start of your sketch :

int aleatoire;

Maybe you got the aleatoire value from a computation in this case you'd need casting and you could use int().
I don't know much about the video performance.

okay the programm is very more clear now!

}
if (affichage==1){tint(255, 255, 255);image(gif,0,0,longueur,largeur);}
}
this is the programme
but now the problem of virtuel memory is the same! :(

I fear there's still a huge lot to do.
Hope someone have some time for it.
