python opencv读mp4视频的实例
如下所示：
#获得视频的格式
videoCapture = cv2.VideoCapture('/home/lw/3661.mp4')
#获得码率及尺寸
fps = videoCapture.get(cv2.CAP_PROP_FPS)
size = (int(videoCapture.get(cv2.CAP_PROP_FRAME_WIDTH)),
int(videoCapture.get(cv2.CAP_PROP_FRAME_HEIGHT)))
fNUMS = videoCapture.get(cv2.CAP_PROP_FRAME_COUNT)
#读帧
success, frame = videoCapture.read()
while success :
cv2.imshow('windows', frame) #显示
cv2.waitKey(1000/int(fps)) #延迟
success, frame = videoCapture.read() #获取下一帧
videoCapture.release()
