Question

如何将以下代码转换为 python？我这样做有问题..

ffmpeg -i /Users/Aaron/lol.mp4 -filter:v "crop=9/16*ih:ih" /Users/Aaron/Desktop/lol1.mp4

非常感谢您的帮助!

Answer 1

您可以进行子流程调用:

import subprocess

def crop(input_file, output_file, x, y):
    subprocess.call(['ffmpeg', '-i', input_file, '-filter:v', 'crop={}/{}*iw:ih'.format(x, y), output_file])

crop('/Users/Aaron/lol.mp4', '/Users/Aaron/Desktop/lol1.mp4', 9, 16)
