AVCaptureStillImageOutput outputSettings memory leak

Question

Hi guys,

I'm experiencing a wierd behavior in the new AVFoundation classes in the iPhone SDK.

I have a AVCaptureStillImageOutput for taking pictures, and I am setting its outputSettings to my liking. The code follows:

 AVCaptureStillImageOutput *stillImageOutput = [[[AVCaptureStillImageOutput alloc] init] autorelease];
[stillImageOutput setOutputSettings:[NSDictionary dictionaryWithObject:AVVideoCodecJPEG forKey:AVVideoCodecKey]];
[self setStillImageOutput:stillImageOutput];

(stillImageOutput property is defined as "retain")

I stumbled upon a leak in leaks, with 100% of the leak fault on the setOutputSettings line. I believe that I confine to the memory management guidelines in the code attached, still it is leaking.

My solution was to

[self.stillImageOutput setOutputSettings:nil];

in the dealloc, just before

[self setStillImageOutput:nil];

The leak indeed stopped, but it looks weird. Shouldn't the releasing of stillImageOutput release its outputSettings property as well?

Anyway, if someone else runs into this, thought I should share my solution.

Cheers!
Oded.
