How to stop os.system() in Python ?

30 septembre 2015, par 吴雨羲

I want to stop the cmd command after 12 seconds. How to stop it ? My program doesn’t work.

import multiprocessing

import os

import time





def process():

    os.system('ffmpeg -i rtsp://218.204.223.237:554/live/1/66251FC11353191F/e7ooqwcfbqjoo80j.sdp -c copy dump.mp4')





def stop():

    time.sleep(12)





if __name__ == '__main__':

    p = multiprocessing.Process(target=process, args=())

    s = multiprocessing.Process(target=stop, args=())

    p.start()

    s.start()

    s.join()

    p.terminate()

I change my program follow Pedro’s suggusetion @Pedro Lobito ,but it still doesn`t work.

import shlex



import subprocess

import time



command_line = 'ffmpeg -i rtsp://218.204.223.237:554/live/1/66251FC11353191F/e7ooqwcfbqjoo80j.sdp -c copy dump.mp4'



proc = subprocess.Popen(shlex.split(command_line), shell=True)

print '1' * 50

time.sleep(2)  # &lt;-- sleep for 12''

print '2' * 50

proc.terminate()  # &lt;-- terminate the process

print '3' * 50

And the result in CMD is

Maybe ffmpeg can reconnection. Can I stop it like ’Ctrl + C’ ?

resize using ffmpeg in python syntax error

26 janvier 2021, par FabricioG
I'm trying to resize a video using ffmpeg in python but am having an error with the syntax. I would expect it to be as easy as this (which is my code)




```
import ffmpeg&#xA;&#xA;ffmpeg -i video.mov -vf "scale=250:150" newmovie.mp4&#xA;
```




this gives an invalid syntax of this :




```
    ffmpeg -i video.mov -vf "scale=250:150" newmovie.mp4&#xA;                  ^&#xA;SyntaxError: invalid syntax&#xA;
```




I tried this :




```
ffmpeg -i video.mov -vf scale=250:150 newmovie.mp4&#xA;
```




and also putting everything file in quotations. No luck.



Any way to assign terminal output to variable with python ?

15 août 2022, par Gordon Fontenot
I need to grab the duration of a video file via python as part of a larger script. I know I can use ffmpeg to grab the duration, but I need to be able to save that output as a variable back in python. I thought this would work, but it's giving me a value of 0 :




```
cmd = &#x27;ffmpeg -i %s 2>&amp;1 | grep "Duration" | cut -d \&#x27; \&#x27; -f 4 | sed s/,//&#x27; % ("Video.mov")&#xA;duration = os.system(cmd)&#xA;print duration&#xA;
```




Am I doing the output redirect wrong ? Or is there simply no way to pipe the terminal output back into python ?
