在python中运行cmd [英] Running cmd in python

问题描述

Atm我将其作为代码，第一行似乎运行良好，但第二行给出了错误信息.

Atm I have this as my code, the first line seems to work well but the 2nd gives errrors.

os.chdir('C://Users/Alex/Dropbox/code stuff/test')
subprocess.call('ffmpeg -i test%d0.png output.avi')

另外，当我尝试以此方式运行它时，它会发出1s的cmd闪烁，然后什么也没发生

Also when I try to run it as this, it gives a 1s cmd flicker and then nothing happens

os.system('ffmpeg -i test%d0.png output.avi')

推荐答案

对于寻找答案的后代来说，这很有用.(您必须用空格将命令分开.)

For the later generations looking for the answer, this worked. (You have to separate the command by the spaces.)

import os
import subprocess
os.chdir('C://Users/Alex/')
subprocess.call(['ffmpeg', '-i', 'picture%d0.png', 'output.avi'])
subprocess.call(['ffmpeg', '-i', 'output.avi', '-t', '5', 'out.gif'])
