java.lang.OutOfMemoryError ESS mp3
Mar 18^th, 2006, 10:13pm

Has anyone had trouble loading mp3 files with ESS? I often get an error that reads:

"Java.lang.OutOfMemoryError"

the problem seems to have something to do with the length of the song. All the files that have worked have been 2:51 or less, and all the ones that have failed are 2:53 or more. I couldnt find a song of length 2:52 to try, but you get the idea.

Any ideas on how to get around this?

Hi,

I tried increasing the heap memory with the:
run.options = -Xms128m -Xmx1024m

but I still get an OutOfMemory error when loading large mp3.

I can see, with TaskManager, the memory going up to 75M and then the app crashes...

Has anyone been able to play, say, a 3 minute mp3?
I'm using Processing 0103.

thanks
jc

Are you playing this from an applet jar? from an exported app? or from within the Processing IDE? If the latter you might want to go into preferences and change the amount of memory Processing allows itself to use. R

System: Win XP

When I checked the "Set memory..." box in Preferences and increased it from 256MB to something close to 9GB...the following error appears:

Invalid maximum heap size: -Xmx9560m
Could not create the Java virtual machine.

I tried playing files below 2MB and they worked. But 4MB etc give the java.lang.OutofMemoryError...
