以编程方式在Python中生成视频或动画GIF？

pip install opencv-python

import cv2
import numpy as np

# 创建一个空白视频帧
frame_width = 640
frame_height = 480
out = cv2.VideoWriter('output.avi', cv2.VideoWriter_fourcc('M', 'J', 'P', 'G'), 10, (frame_width, frame_height))

# 生成一些简单的动画
for i in range(100):
    # 创建一个黑色背景的画布
    canvas = np.zeros((frame_height, frame_width, 3), dtype='uint8')

    # 在画布上绘制一个矩形
    x = i * 6
    y = i * 4
    w = 50
    h = 50
    cv2.rectangle(canvas, (x, y), (x+w, y+h), (255, 0, 0), -1)

    # 将画布添加到视频中
    out.write(canvas)

# 释放资源
out.release()
