Access GPU context, hooking into VR service pipeline

[Harsh2098]

Can this framework be used to solve this problem ?

Is it possible to access any VR Android app's GPU context i.e. what images/graphics the other VR app is rendering on screen from our custom app. I want to get the images rendered by other VR app and apply custom distortion. If yes, how can it be achieved?

My idea was to hook a service the the buffer stream, i.e. read whatever is going to be displayed on screen, apply custom distortion/filter and display it back. Will SwapChain from gvr-android-sdk work in this scenario? Reading GPU buffer from an android service and displaying it back. (For now we don't worry about the DRM protection etc. later we'll be askig for permissions)
