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

I try the original code showed in the below link: https://www.processing.org/reference/libraries/video/Movie_speed_.html

It is still not working
The Processing can run my video, but the speed never ever change.

Thanks to your reply

Oh!!!
Got it! It is working for this example!
I will try it again in my sketch!
Thank you kll!

My system is Mac…
Just now I thought that you ask me to try the example code of website.
Just now I tried the example inside of processing. It is working now!!!

Thank you so much!!!

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 !
