视频读取demo

if not videoCapture.isOpened():  # 若视频文件读取失败，读取下一段视频print('视频打开失败!!!')print(video_path)return False
total_frames = int(videoCapture.get(cv2.CAP_PROP_FRAME_COUNT))  # 获取视频总帧数
# fourcc = int(videoCapture.get(cv2.CAP_PROP_FOURCC))  # 原生不支持h264编码
fps = videoCapture.get(cv2.CAP_PROP_FPS)  # 获取视频帧率
w = int(videoCapture.get(cv2.CAP_PROP_FRAME_WIDTH))  # 获取图像宽度
h = int(videoCapture.get(cv2.CAP_PROP_FRAME_HEIGHT))  # 获取图像高度pbar = tqdm(total=total_frames)  # 进度条显示
while total_frames:success, curr = videoCapture.read()if success:cv2.imshow('frame', curr)# cv2.waitKey(0)=='q'
