帧未在scikit视频输出中自动更新

Question

我正在使用与此类似的代码

from skvideo.io import VideoCapture
cap = VideoCapture(filename)
cap.open()

while True:
retval, image = cap.read()

# image is a numpy array containing the next frame
# do something with image here
plt.show()
if not retval:
    break

但是输出仅显示一帧，而第二帧仅在我关闭第一帧后显示。 scikit中是否有类似于cv2.waitKey（）和cv2.destroyAllWindows（）的函数来自动更新帧？

Answer 1

尝试正确缩进代码，如下所示：

 from skvideo.io import VideoCapture
 cap = VideoCapture(filename)
 cap.open()

 while True:
    retval, image = cap.read()

    # image is a numpy array containing the next frame
    # do something with image here
    plt.show()
    if not retval:
        break
