PyAV:如何同时向屏幕显示多个视频流

import av

import cv2

window_name = "Multiple Video Streams"
cv2.namedWindow(window_name, cv2.WINDOW_NORMAL)

container = av.open('video1.mp4')  # 打开第一个视频流
container2 = av.open('video2.mp4')  # 打开第二个视频流

for frame, frame2 in zip(container.decode(video=0), container2.decode(video=0)):
    img = frame.to_image()  # 将帧转换为图像
    img2 = frame2.to_image()
    
    img = cv2.cvtColor(np.array(img), cv2.COLOR_RGB2BGR)  # 转换颜色空间
    img2 = cv2.cvtColor(np.array(img2), cv2.COLOR_RGB2BGR)
    
    # 调整图像大小以适应窗口
    img = cv2.resize(img, (640, 480))
    img2 = cv2.resize(img2, (640, 480))
    
    # 在窗口中显示图像
    cv2.imshow(window_name, np.hstack((img, img2)))
    
    # 按下'q'键退出循环
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

# 释放窗口和视频流容器
cv2.destroyAllWindows()
container.close()
container2.close()
