Exporting an Application w/ very large data folder

in General Discussion • Other • 1 years ago

I'm using Processing to code up a social science experiment for my lab that displays short movie clips to subjects. I realized about midway through that Processing is fantastic for creating visuals, but perhaps not the best for loading and displaying pics/videos; but I think it can be good enough.

My sketch works well but I'd like to export it as an application for Windows, so that it can be distributed to other labs w/o issue and can be full-screen. During export, however, I get a Java error: which I assume is related to the size of the data folder (it's ~500MB) as I've successfully exported to apps before. Any ideas? Some threads on this error suggested increasing the heap space through a java_args.txt file but everyone mentioned different commands and I couldn't get it to work.

Thanks everyone,

Don

" I get a Java error"
As I can't guess what error it is, I suggest you show it here.

If you're correct, it tries to place the entire data folder in the jar file, which is not necessary. What you could do is temporarily move the data folder out of your sketch directory, export the sketch. Then copy the data folder to the Windows Application folder of your exported sketch (along side the .exe). The application should be able to find it there and it doesn't have to go through the jar (compression) to get the files.

You could also load the movies from an Absolute or Relative path outside of your sketch folder... but make sure that the directory is still inside of your application package that you share...
