iOS How can I be in control of AVCaptureSession?

Hi Guys,

I need to implement this but also use each frame image data for other purposes. I need to integrate it with GPUImage.

How can I get full control of the video feed?

Right now I am using OpenTok implementation (which uses Google's) which allows me to take care of the video feed by my self. Here's an example how I could integrate OpenTok with GPUImage, I need something similar with yours WebRTC implementation. Is it possible? Thanks
