I've got a .mov I wish to play with GSVideo rendered in OpenGL, however I get very slow performance. I've seen this thread:
http://forum.processing.org/topic/gsvideo-poor-performance-with-opengl which helped a bit, but there aren't many details to go on.

ANyone know how I can speed up the playing of a movie?

This example code is very slow for example (OSX Leopard, Processing v1.2.1, GLGraphics 0.9.4, GSVideo 0.7):

import processing.opengl.*;
import codeanticode.glgraphics.*;
import codeanticode.gsvideo.*;

GSMovie myMovie;
GLTexture tex;

void setup() {
  size(640, 480, GLConstants.GLGRAPHICS);
  background(0);
  // Load and play the video in a loop
  myMovie = new GSMovie(this, "mymovie.mov");
  myMovie.loop();
 
  tex = new GLTexture(this);
}


void movieEvent(GSMovie myMovie) {
  myMovie.read();
}


void draw() {
  //tint(255, 20);
 
  tex.putPixelsIntoTexture(myMovie);
  image(tex, mouseX-myMovie.width/2, mouseY-myMovie.height/2,50,50);
}

Edit:
I should say that the movie is big at 1920x1080. The same code with station.mov works ok.
