  • Unable to execute command prompt command from python

    30 octobre 2023, par StudentProgrammer

    Unable to execute a ffmpeg command directly from python, however it works fine if used within the command prompt.

    


     os.system("cmd /c ffmpeg -i video.mp4 -i sound.mp3 -c:v copy -filter_complex '[1:a] adelay=3000|2000 [delayed]; [0:a] [delayed] amix [out]' -map 0:v -map '[out]' video2.mp4")



 '2000' is not recognized as an internal or external command,
 operable program or batch file.


    


    I know it has something to do with the pipe |. I've looked at documentation to make subprocess work with pipes but without success.
