What is the cause of this retain cycle? and is there a way to force memory to be deallocated?

I've been searching for a solution to this problem, without success, for sometime.

I use OpenTok Video Framework to publish a video stream from the device camera to an online service. I use their publish/unpublish methods as documented.

Problem: The memory allocated by [GLVideoProcessor createFrameBuffers] never gets deallocated, even when its parent VC is deallocated and the framework's unpublish method is called(and delegated nil'ed).

Question 1: Without being able view the framework's .m files, is there a way to force memory to be released?

Request 2: Any other advice about how to solve this problem would be greatly appreciated.

Occurs in: Xcode 4.6 & Xcode 5
iOS6 & iOS7

Instruments: The doPublish method alloc's OTPublisher and initiates the stream. Overview

Multiple Instances of Publish/Unpublish being called and never being deallocated. Shows GLVideo staying alive
