How do I switch videos using gsvideo?

in Contributed Library Questions • 2 years ago

Hi there!

I'm fairly new to processing and I'm having real difficulty playing a video then after a timer changing the video e.g. Play the first video till timer reaches a certain point then stop the first video and activate the second. So far I have got it to the stage that the video will just start playing the second video regardless. Eventually I want to be able to trip the changing to the next video using some sensors that will out put a b oolean true or false. I'm using gsvideo at the moment as it seemed to be working best for me but am open to suggestions. (the files i am playing are .mov).

Cheers

The GSMovie class has play/stop/pause methods that should allow you to do what you want. It sounds more like there is a problem in the logic of your program. Maybe if you post some code it would be easier to see where the problem is.

Hi,

Thanks for the reply I fixed it and you were right it was my logic!

This is the program any tips on how i can improve it?

import codeanticode.gsvideo.*;

GSMovie myMovie;

int timer;

int timelength = 9000;

int flag1;

int flag2;

void setup() {

println("Starting program");

size(1280, 720, P3D); //set size of the video

background(0); //Runs setup of the phidget

steps(); //Runs the steps segment of the program

timer = millis();

}

void steps() {

if (flag1 == 0 ) {

println("Starting Video 1");

myMovie = new GSMovie(this, "ellie1.mov");

println("Video 1 loaded");

myMovie.play();

flag1 = 1;

}

else if (millis() - timer > timelength && flag2 != 1) {

println("Starting Video 2");

myMovie.stop();

myMovie = new GSMovie(this, "ellie2.mov");

println("Video 2 loaded");

myMovie.play();

println("looping Video 2");

flag2 = 1;

}

void movieEvent(GSMovie myMovie) {

println("Move start");

myMovie.read();

steps();

}

void draw() {

image(myMovie, 0,0);

}

I would put each video in a separate movie object, and load both in setup. Something like this:

import codeanticode.gsvideo.*;
int timelength = 3000;
GSMovie mov1, mov2;
boolean playing1, playing2;
void setup() {
size(400, 400, P3D);
background(0);
// First movie is playing.
mov1 = new GSMovie(this, "ellie1.mov");
mov1.play();
playing1 = true;
// Second movie is paused.
mov2 = new GSMovie(this, "ellie2.mov");
mov2.pause();
playing2 = false;
}
void movieEvent(GSMovie mov) {
mov.read();
}
void draw() {
// We don't need the initial value of millis because it always starts at zero.
if (millis() > timelength) {
// Pausing movie 1.
mov1.pause();
playing1 = false;
// Starting to play movei 2.
mov2.play();
playing2 = true;
}
if (playing1) {
image(mov1, 0,0);
}
if (playing2) {
image(mov2, 0,0);
}
}

I Think I get the way to use GSMovie with mulitple videos now.
