The choice of "brain" for a quadcopter?

Question

Arduino

Good day friends, I decided to assemble a quadcopter, I figured everything out, it remains to decide on its brain
, the brain should be enough for the parallel execution of all these functions:
Stream processing and video transmission Hd 40+ fps
Interrogation and transmission of gyroscope and accelerometer readings.
Sensor data processing and control of 5 engines Recalculation of readings about 10 times per second
Camera rotation (the drive is already ready)
Internet connection for data transfer and control, the
list is considerable, and I will probably do an autopilot
as the brain had options to take a raspbery pi or a miniaturized motherboard from a compact pc (there are no pins like on arduino for control, which complicates the task)
I am tormented by the question of whether it is enough to sort it out for these purposes or to take something else, advise
also in which programming language to carry out the transfer, control, etc.
I will be glad to hear the answers

Answer 1

What did you mix.
The brains will always be a specialized flight controller with a set of sensors and nothing more. It is loaded only with route calculation (autopilot), flight mode selection, gimbal control and communication with sensors and equipment.
For video transmission, a separate controller / transmitter is always used, often with its own battery with its own personal antenna of the desired frequency
. and do what you want with it. But never give him full control of the flight controller, send control commands to the controller via a common bus.
