myMovie.speed() is not working

Processing Libraries

Hi friends, I am Anty and I want to control the movie’s speed by .speed() but it seems not working in my code. Whatever the number I wrote to “.speed(0.5)” “.speed(5)” all of them are the same speed.

This is my code:

import processing.video.*;

Movie m;

void setup(){
  iRate=0.5;
  size(500,300);
  frameRate(30);
  m=new Movie(this,"m.mov");
 
  m.speed(0.1);
  m.loop();
  
  
}

void draw(){
  if(m.available()){
    m.read();
    
  }
  image(m,0,0,width,height);
  
  
}```


Thank you for your answer!

Hey There!

https://www.processing.org/reference/libraries/video/Movie_speed_.html

Seems like you have the same exact thing ! But your omg has width and height did you try and see how it works without the width and height variables present ?

Hi friend,
Thank you!
I tried it without heigh and width variables present. It still doesn’t work with the speed. And I followed the guide of the link that you put. I cannot get more information about speed. It is not working…

<I want to achieve a function that the video’s speed follow with the music’s loudness or music’s frequency so that’s why I need control the speed of video. As well as before I used this way, I have tried to use frameRate() to control the image’s appear’s speed, but it is also not working well, because the frameRate() became slower and slower :frowning: >

Hi kll

The Processing can run my video, but the speed never ever change.

Thanks to your reply

I actually found out what is the problem. You must set the speed while the movie is playing ! in your original code, you just need to move the m.speed(0.1); to the line after m.loop();.
Hope this works and helps !
