ofQuickTimeGrabber::listDevices memory leak?

bugs, errors
#1

Hi!
When I compile the movieGrabber example I get several warnings like this (full output below)

  
2011-10-01 17:09:32.349 movieGrabberExampleDebug[2351:903] *** __NSAutoreleaseNoPool(): Object 0x1410280 of class NSCFArray autoreleased with no pool in place - just leaking

Having a look with the leak tool in instruments seems that there are indeed some leaks in listDevices(), qtSelectDevice and loadSettings (see responsible frame in the attached image)

I haven’t seen anything obvious, but I’m far from familiar with quicktime. Haven’t filed a bug because I might be doing something wrong. If anyone confirms I’ll file a bug in github

Here’s the full output

i see this error all the time and don’t understand what exactly is wrong. it’d be great if someone with more quicktime experience could check it out and offer some advice. it’s definitely a bug though.

thanks Kyle. I’ve reported.
