i have been working on a sketch which plays a quite large array (about 40) of  short video clips  - 30-90 seconds at 1280x720 resolution- activated by a sensor when someone is in the room

when the room is empty the sketch plays a short 3 sec video on a loop until someone comes into the space
and then the sequential array begins again

the sketch works for a bit, then bogs down losing sync and completely crashes

i am getting the following error message
 JNA Callback org.gstreamer.elements.AppSink$33@2ffe7 threw the following exception:
java.lang.Out of MemoryError: Java heap space

i am a completely newbie to processing (or programming at all)

it seems to be a memory leak?
this is my code..does anyone have any suggestions for me?
with thanks

i am a grad student and new to processing
i am working on a piece with an array of video clips
i want the array to be accessed consecutively until the array has been completed at which point it would begin at zero
again
at the moment the mouse press sets it back to the beginning
i am not sure how to fix this
can anyone help?
please find my code below
thanks


import processing.video.*;

int maxmyMovies=5
;  //total # movies
int myMoviesIndex=0;  //initial movie to be displayed

Movie[] myMovies = new Movie[maxmyMovies] ; //declare array of movies

  size(1280, 720);
   for (int i=0; i<myMovies.length; i++) {
    myMovies[i] = new Movie(this, "trans"+i+".mov");  //loading movies into the array
  }
  myMovies[myMoviesIndex].loop(); //play the first movie
}
void draw() {
  image(myMovies[myMoviesIndex], 0, 0, 1280, 720);   //display one movie

i am currently trying to write a sketch using  a series of HD video clips with sync sound
they are .mov files in H264
but the sound is not sync'd to the video when i run the sketch
any suggestions?

i am brand new to processing (and not a coder)
i downloaded processing 2.0 today
i am trying to get a video to play and am getting the audio but not the image
does anyone have any suggestions for me
thanks


import processing.video.*;
Movie myMovie;

void setup( ) { 
size(1080, 920);
myMovie = new Movie(this, "trailer copy.mov");
myMovie.play();

}

void draw()  {
 image(myMovie, 0, 0);
}

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

}
