Of course, I keep forgetting about ARC. Thanks.

Is this an ARC-enabled

Is this an ARC-enabled application? Do you keep a reference to your GPUImageVideoCamera and GPUImageView as instance variables? If not, your video camera and your entire video pipeline will be deallocated as soon as your set method has finished. You need to retain at least the video camera object for as long as you want to run your video capture.
