如何在opencv中将视频分辨率更改为1440p

video = cv2.VideoCapture('video.mp4')
width = int(video.get(cv2.CAP_PROP_FRAME_WIDTH))
height = int(video.get(cv2.CAP_PROP_FRAME_HEIGHT))

fourcc = cv2.VideoWriter_fourcc(*'mp4v')
output = cv2.VideoWriter('output.mp4', fourcc, 30, (2560, 1440))

while True:
    ret, frame = video.read()
    if not ret:
        break
    
    # 将帧的分辨率更改为1440p
    resized_frame = cv2.resize(frame, (2560, 1440))
    
    # 将处理后的帧写入新的视频文件
    output.write(resized_frame)

video.release()
output.release()
