Trying to use the MovieMaker class from the video library within ruby-processing has thrown this error at me:
quicktime.std.StdQTException[QTJava:7.6.0g],-5000=afpAccessDenied,QT.vers:7608000
     at quicktime.std.StdQTException.checkError(StdQTException.java:38)
     at quicktime.std.movies.Movie.createMovieFile(Movie.java:115)
     at processing.video.MovieMaker.initMovie(MovieMaker.java:231)
...

Just wondering if anyone else has run up against this, or if you have suggestions of where else I can look to try solving this. I'm concerned that I might need to recompile the .jar for the video library or come up with a different means of creating movies (like saving every frame and assembling in another program).

I confirmed that I can create movies using the MovieMaker class from within the Processing IDE. It's only when I try to load it in ruby-processing that a permission error is thrown.

I included the library like this:
Code:

class Chart < Processing::App
  
  load_libraries :video
  import 'processing.video.MovieMaker'
  
  def setup
    @do_record = false
    @mm = MovieMaker.new( self, width, height, "drawing.mov", 30, MovieMaker::H264, MovieMaker::HIGH )
  ...
  end
...
end
 

Thanks.

David -- The MovieMaker works just fine for me on a 32-bit machine, no tricks or hacks required. Here's a video, followed by the sketch that made it:

Give that sketch a try and let me know what happens. If it doesn't work, please post back your platform and environment details.

I had trouble with H264 too (although with a different system and regular Processing), I made a little test script to check all available formats for my installation: Test of MovieMaker video type.
Maybe this can help.
