how to load movie file paths into array

karl_hungus

how do i load movie file paths into array so i don't need to specify them for each movie instance?

this is how i would do this for image files:

PImage[] p = new PImage[20];

for (int i = 0; i < p.length; i++) {
    p[i] = loadImage("v"+nf(i, 2) + ".jpg"); 
  }

but what to use for movie files?

GoToLoop

• Your example isn't storing paths, but actual PImage instances.
• In the Processing's IDE, hit CTRL+SHIFT+O in order to open examples
• Click on: Libraries -> video -> Movies.
• You'll find many examples there!

that's the problem,i wanted to know how to store paths! in Libraries -> video -> Movies all examples use single video file

like: String PATH= "/home/video01.mp4"; Movie mov; mov =new Movie(this,PATH);

how do i scan some folder with few video files and then store in array to use PATH[0], PATH[1] etc.

GoToLoop

Arrays use the same [] syntax. As you did for PImage: PImage[] imgs = new PImage[20];,
do the same for Movie: Movie[] movs = new Movie[5].

For paths you can use String[]: String[] paths = new String[movs.length];

//ok, make array, easy
    Movie[] movs = new Movie[5]
     String[] paths = new String[movs.length];

  //but confused about this 
    for (int i = 0; i < movs.length; i++) {
//how to load files i got in my data folder or somewhere else?
        paths[i] = ???
      }

hi, thank you, for some reason i got "could not load movie file message" where's my mistake?

import processing.video.*;

static final String FILE = "video", EXT = ".mp4";
static final int NUM = 5;

final String[] paths = new String[NUM];
Movie mov;

void setup(){

  size(320, 240,JAVA2D);
  String folder = dataPath("") + "/";
  println(folder);
  println();

  for (int i = 0; i != NUM; println(paths[i++] =
    folder + FILE + nf(i, 2) + EXT));

  exit();
  mov =new Movie(this,paths[0]);
  mov.loop();

}

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

}

void draw(){
  background(255);
  image(mov, 0, 0, width, height);

}
