AVCaptureDevice:: video raw capture? ios RTOS kernel extensions?

for iphone 6, apple does not support raw mode but there is an app that performs this feature.


is there a spreadsheet that lists available pixels? bus speed per devices?


if i want my app to be able to override and stomp on, with user permission, any other app and run exclusive in near real-time as device limitations permit, how would this be accomplished? with what framework? i need to be able to shoot the other services in the head, i.e., break the sandbox, in normal unix, i would just write a RTOS kernel extension but since apple probably doesn't allow this, what options are available?
