ADB - Fastest screenshots - scrcpy raw stream directly to NumPy (without scrcpy.exe) - no root required!

Tested against Windows 10 / Python 3.10 / Anaconda

pip install adbblitz

with Google Pixel 6 - not rooted

TCP - Taking multiple screenshots

Check out the native ADB (!) version - as fast as scrcpy, but no installs: https://github.com/hansalemaos/adbnativeblitz

If you want to take multiple screenshots using a TCP connection, you can use AdbShotTCP

Import the modules

from adbblitz import AdbShotUSB, AdbShotTCP

Use 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.

from adbblitz import AdbShotUSB, AdbShotTCP
import numpy as np
from time import time
import cv2


with AdbShotTCP(
    device_serial="localhost:5555",
    adb_path=r"C:\ProgramData\chocolatey\lib\scrcpy\tools\scrcpy-win64-v2.0\adb.exe",
    ip="127.0.0.1",
    port=5555,
    max_frame_rate=60,
    max_video_width=960,
    scrcpy_server_version="2.0",
    forward_port=None,
    frame_buffer=24,
    byte_package_size=131072,
    sleep_after_exception=0.01,
    log_level="info",
    lock_video_orientation=0,
) as shosho:
framecounter = 0
stop_at_frame = None
fps = 0
start_time = time()
show_screenshot = True
# print(shosho)
for bi in shosho:
    if bi.dtype == np.uint16:
        continue
    cv2.imshow("title", bi)
    if cv2.waitKey(25) & 0xFF == ord("q"):
        # cv2.destroyAllWindows()
        # shosho.quit()
        break
    fps += 1
print(f"fast_ctypes_screenshots: {fps / (time() - start_time)}")

TCP - Taking one screenshot at the time

If you take only one screenshot, the connection will stay open until you call AdbShotTCP.quit()

a = AdbShotTCP(
	device_serial="localhost:5555",
	adb_path=r"C:\ProgramData\chocolatey\lib\scrcpy\tools\scrcpy-win64-v2.0\adb.exe",
	ip="127.0.0.1",
	port=5037,
	sleep_after_exception=0.05,
	frame_buffer=4,
	lock_video_orientation=0,
	max_frame_rate=0,
	byte_package_size=131072,
	scrcpy_server_version="2.0",
	log_level="info",
	max_video_width=0,
	start_server=True,
	connect_to_device=True,
)

scr = a.get_one_screenshot()
scr.quit() # closes the connection

USB - Taking multiple screenshots

Same thing for USB

with AdbShotUSB(
    device_serial="xxxxx",
    adb_path=r"C:\ProgramData\chocolatey\lib\scrcpy\tools\scrcpy-win64-v2.0\adb.exe",
    adb_host_address="127.0.0.1",
    adb_host_port=5037,
    sleep_after_exception=0.05,
    frame_buffer=4,
    lock_video_orientation=0,
    max_frame_rate=0,
    byte_package_size=131072,
    scrcpy_server_version="2.0",
    log_level="info",
    max_video_width=0,
    start_server=True,
    connect_to_device=True,
) as self:
    start_time, fps = time(), 0
    for bi in self:
        if bi.dtype == np.uint16:
            continue
        cv2.imshow("test", bi)
        fps += 1
        if cv2.waitKey(25) & 0xFF == ord("q"):
            cv2.destroyAllWindows()
            break
    print(f"FPS: {fps / (time() - start_time)}")
    cv2.destroyAllWindows()
