Using the library without loading the file into memory?

[jpmurray]

Is it at all possible? Would it be?

I'm using the library for the getTotalDuration() function, and, I just hit a (kind of) large file of 480mb that, of course, hits the allowed memory size (which is set to 512m in php.ini).

Sure, I could change the value in php.ini, and probably could use ini_set('memory_limit', '1024M') before the library runs, but I have to wonder... Is there no other way to get this info other than loading the file into memory / reading it all?
