preamble
This article provides the tool method to cut the video in the time dimension, as always pragmatic.
environmental dependency
ffmpeg environment installation, you can refer to the end of the article to add content
This article mainly uses not ffmpeg, but ffprobe.
ffmpy installation:
pip install ffmpy -i /simple
coding
No bullshit, on to the code.

'0:10', 5))Code Description
1, cut_video_by_time method parameters are, respectively, the input video address, the output directory address, cut start time point, cut duration.
2, the format of the starting time to pay attention to, give a few format styles: 0:01, 10:11, in front of the minutes behind the seconds.
3, made a simple video format verification, such as the need to add, you can watch yourself.
4. Use uuid for the final video name to avoid duplication.
5. The length of the cut video cannot exceed the video time.
Verify it.
Prepared video information.
