推荐答案

另一个建议是使用 moviepy .

要获得持续时间，可以使用 VideoClipFile

For getting a duration you can use VideoClipFile

from moviepy.editor import VideoClipFile

video = VideoClipFile(<path to your video file or a video file object>)

video.duration  # this will return the length of the video in seconds

要获取缩略图，您可以使用Pillow中的 Image

For getting a thumbnail, you can use Image from Pillow

from PIL import Image

frame_data = video.get_frame(1)  # 1 means frame at first second

img = Image.fromarray(frame_data, 'RGB')

然后对图像进行任何操作.

And do whatever you want with the image.
