Python API for live video feed of phone screen

• I have checked that a similar feature request does not already exist.

Is your feature request related to a problem? Please describe.
It is not. I am developing a project where I need a live feed of the phone screen. I tried repeatedly taking screenshots with adb but that is slow. I can't record the screen because I need the video feed live.

Describe the solution you'd like
A Python API which will allow me to programmatically access the live feed of the phone screen. Probably setup so that there is a thread in the background receiving the screen data and storing it into a variable. Thus, when I call a method, it will return to me the latest value in that variable with no latency. The return type could be a Pillow image object or (preferably) a NumPy array with the pixel values.

Describe alternatives you've considered
I have considered starting scrcpy on my computer and periodically taking screenshots of the window but this is slow and the latency is too great for my use case.

No files, tests, or entry points are named in the issue. Start by reviewing scrcpy's existing interfaces and the requested live-feed behavior; done means a defined, usable Python interface that returns current phone-screen frames with the requested low latency.
