support for online processing

Hi, does this code support for online processing. For example, a camera captures video in a real time way, we need to process each frame when we receive it

There have been some small tests with this e.g. https://github.com/ElvinC/gyroflow/blob/master/test%20scripts/live_stab.py which sort of worked but isn't practically usable yet due to the timing requirements
