Here i got the code of a program i’ve compiled in 2008 for a art project. because of changes in programming en technics, its out of date and doesn’t function any more. I’m going to try and explain what i’ve tried so far, and as i’m a little rusty with coding i could use some help fixing my code.(code below so you can run it and try)
So i loaded my old proccesing file that colapsed prossing al together. then i opened it in plain tezt an loaded that code directly in to a new sketch. and as expected. i get the my first error
“No library found for fullscreen
Libraries must be installed in a folder named ‘libraries’ inside the sketchbook folder (see the Preferences window).
The package “fullscreen” does not exist. You might be missing a library.”
this is true, so i took the old lib file i had and put it in the right directory. then the new error
“Duplicate libraries found for processing.core. in conflict with fullscreen lib. extra libs must be removed for this sketch to work. “
so i removed the fullscreen lib again. and made sure the sketch would not try and load the fullscreen.lib that works bu then a lot of the code is based on this libary. but ok then lets try without all the commands using the code. so in debug it runs down the lines of code not working. so far ok until i get to line 23
“ClassNotFoundException: quicktime.std.StdQTException”
And i get this other erros “arraycopy(video.pixels, backgroundPixels);” on line 42,60,116
and most important on line 73 “int presenceSum = 0;”
this 4 line are important for the programma to do its thing. anyone willing to help me out sorting this mess

program created for art installation using code for lots of source put together
so that we get a full screen video that shows only the difference between now and a random time in the past
