本文介绍了如何使用Python库在RaspberryPi上，通过Adafruit_SSD1306模块，将视频文件中的每一帧转换为灰度并调整尺寸后显示在128x32的OLED屏幕上，实现视频实时监控的简易系统。

import Adafruit_GPIO.SPI as SPI
import Adafruit_SSD1306
from PIL import Image

# Raspberry Pi pin configuration:
RST = 24
DC = 23
SPI_PORT = 0
SPI_DEVICE = 0

# 128x32 display with hardware I2C:
disp = Adafruit_SSD1306.SSD1306_128_32(rst=None, i2c_bus=1, gpio=1)

# Initialize library.
disp.begin()

# Clear display.
disp.clear()
disp.display()

# Open the video file
cap = cv2.VideoCapture('932592103.mp4')

# Check if the video file opened successfully
if not cap.isOpened():
print("Error: Unable to open video file.")
exit()

# Read and display each frame
while cap.isOpened():
    ret, frame = cap.read()
    if not ret:
        break

    # Convert the frame to grayscale
    gray_frame = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    # Resize the frame to fit the OLED display
    resized_frame = cv2.resize(gray_frame, (disp.width, disp.height))

    # Convert the frame to PIL Image
    pil_image = Image.fromarray(resized_frame).convert('1')

    # Display image.
    disp.image(pil_image)
    disp.display()

    # Delay to control frame rate (adjust as needed)
    time.sleep(0.1)
