ADB - Fastest screenshots - scrcpy raw stream directly to NumPy (without scrcpy.exe) - no root required!
If you want to take multiple screenshots using a TCP connection, you can use AdbShotTCP
Import the modules
from adbblitz import AdbShotUSB, AdbShotTCPUse the with statement to create an instance of the AdbShotTCP class and specify the required parameters
Within the with block, you can iterate over the shosho object to capture screenshots After everything is done, the socket connection will be closed, you don't have to take care about anything.
