Getting dimensions of a quicktime movie
Jun 3rd, 2010, 3:21pm  
Hi,
is there a way to get the dimensions of a quicktime movie? I can't find anything in the Movie class. Are there any other ways?

Thanks,
Alex

Thanks. Unfortunately, that didn't work - I always get dimensions of 1x1, no matter which video file I use. But I think something's wrong in general.  I have the following code:

import processing.video.*;

Movie mov;

void setup()
{
 size(500, 500);
 mov = new Movie(this, "cancun.mov");
 print(mov.duration());
 mov.play();
}

void draw()
{
 if (mov.available())
   mov.read();
 image(mov, 0, 0);
}

The duration is displayed correctly, but I always get the following exception at the last line: ArrayIndexOutOfBoundsException: Corrdinate out of bounds!
If I leave that line out for debugging purposes, I get this:
java(749,0xb1636000) malloc: *** error for object 0x12904d0: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Invalid memory access of location 0xffffffff eip=0x9333e5c8

This happens regardless of which movie is being played back. Is something broken here?
I'm on Snow Leopard 10.6.3 and have Quicktime X, if that helps.

hmm strange, i just checked it and it seems like there is a bug. I tested the standard movie playback code examples from the reference and got the same error. But when using it in an older version of processing, in this case 148, everything was alright.  I cant tell where exactly the problem is, but it looks like it is not your fault but a processing bug.

I've had the same issue with the standard movie library in Processing.

However, when I need to switch between movies I use the JMC Library, the video.width and video.height functions work with it quite well.
