    <p>I've been searching for a solution to this problem, without success, for sometime.</p> <p>I use <a href="http://opentok.github.io/opentok-ios-sdk/index.html" rel="nofollow noreferrer">OpenTok Video Framework</a> to publish a video stream from the device camera to an online service. I use their publish/unpublish methods as documented. </p> <p><strong>Problem:</strong> The memory allocated by <code>[GLVideoProcessor createFrameBuffers]</code> never gets deallocated, even when its parent VC is deallocated and the framework's unpublish method is called(and delegated nil'ed). </p> <p><strong>Question 1:</strong> Without being able view the framework's .m files, is there a way to force memory to be released?</p> <p><strong>Request 2:</strong> Any other advice about how to solve this problem would be greatly appreciated.</p> <p>Occurs in: Xcode 4.6 &amp; Xcode 5<br> iOS6 &amp; iOS7</p> <p>Instruments: The doPublish method alloc's OTPublisher and initiates the stream. <img src="https://i.stack.imgur.com/CRrXZ.png" alt="Overview"></p> <p>Multiple Instances of Publish/Unpublish being called and never being deallocated. <img src="https://i.stack.imgur.com/gwptB.png" alt="Shows GLVideo staying alive"></p> <p>ARM view of <code>[GLVideoProcessor createFrameBuffers]</code></p> <p><img src="https://i.stack.imgur.com/SBEvy.png" alt="enter image description here"></p> <p>ARM view of <code>[GLVideoProcessor createFrameBuffers]</code> + Backtrace <img src="https://i.stack.imgur.com/XuEXi.png" alt="enter image description here"></p>

    1. COWhy are you posting here and not on http://tokbox.com/forums/ios/? Looking at the URL for the documentation for this, there is virtually nothing to go on, and you have given us no code on how you set this object up. Look in the .h files and see if there is some exposed property, one idea. My guess is that you are holding on to a reference to some object somewhere that is blocking the memory dealloc, but its obviously just a guess.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
