I encounter a few different problems while playing movies:

on MacPro
Processing 0133
QuickTime version: 7.3.0
MacOS 10.4.10 (intel)

Sketch runs fine initially, but after 3 minutes i get these error messages:
java(4260,0xa000d000) malloc: *** error for object 0x1baa7230: double free
java(4260,0xa000d000) malloc: *** set a breakpoint in szone_error to debug

One minute later:
Invalid memory access of location ffffffff eip=9171b83c
(then Processing.core.PApplet crashed)

I tried this with several movies and I got similar results.

behaviour on Powerbook G4 :
Processing 0133
QuickTime version: 7.3.0
MacOS 10.4.10 (PPC)

Processing.core.PApplet opens as a new window, but stays white/grey: inactive and not
running. There is nothing processing, but no error messages though.


Code:
------
import processing.video.*;

Movie myMovie;


void setup() {
size(640, 480, P3D);
background(0);
// Load and play the video in a loop
myMovie = new Movie(this, "hproc.mov"); // tried several movies other than example
movie
myMovie.loop();
}


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


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

unfortunately i don't think there's much we can do about this. sometimes
encoding the movie with another codec will help.
