analyze sound levels with sound library & random video (warning: 140)

hi, i'm new with processing code. i'm trying to change video footage, with visual effects based on audio in. the code works, but after a while (1-3 random video changes) it stuck and the video or the effects stop working, everything freez (including println lines..)

most of time, if the sound level getting higher, that happens. i get the same warning message everytime:

2016-01-24 23:38:55.263 java[49121:34205664] 23:38:55.263 WARNING: 140: This application, or a library it uses, is using the deprecated Carbon Component Manager for hosting Audio Units. Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h.

this is the code so far:

import processing.video.*;
import processing.sound.*;

AudioIn input;
Amplitude rms;
int scale;
Movie myMovie;

String[] one = {"a.mp4","b.mp4","c.mp4"};

int a = 0;
float md = 0;
float mt = 0;

void setup()
{
  size(1440 ,900);
  frameRate(25);
  background(0);
  myMovie = new Movie(this, one[int(random(one.length))]);
  myMovie.play();
  input = new AudioIn(this, 0); //Create an Audio input and grab the 1st channel
  input.start(); // start the Audio Input
  rms = new Amplitude(this); // create a new Amplitude analyzer
  rms.input(input); // Patch the input to an volume analyzer
}

void draw()
{
  scale=int(map(rms.analyze(), 0, 0.5, 1, 350));

  if(a == 0) {
      image(myMovie, 0, 0,900,900);
      }
  image(myMovie, 0, 0,900,900);

  float md = myMovie.duration();
  float mt = myMovie.time();
  println(md - mt);
  if (Math.abs(md - mt)<0.1){// to find the end of the movie
     myMovie = null;
     myMovie = new Movie(this, one[int(random(one.length))]);
     myMovie.play();
  }
// rms.analyze() return a value between 0 and 1. To adjust the scaling and mapping of an ellipse we scale from 0 to 0.5
    if ((rms.analyze()>0)&&(rms.analyze()<3))
    tint (scale*20,scale*4,scale*4);
    myMovie.speed(scale*0.2);

}

void movieEvent(Movie m) { // Called every time a new frame is available to read
  m.read();
}

what am i doing wrong? any help will be great! thanks, Ravit :)
