  • FFMpeg giving invalid argument error with python subprocess

    23 janvier 2020, par Emre Erol

    I am trying to convert a file or microphone stream to 22050 sample rate and change tempo to double. I can do it using terminal with below code ;

    #ffmpeg -i test.mp3 -af asetrate=44100*0.5,aresample=44100,atempo=2 output.mp3

    But i can not run this terminal code with python subprocess. I try many things but every time fail. Generaly i am taking Requested output format ’asetrate’ or ’aresample’ or ’atempo’ is not suitable output format errors. Invalid argument. How can i run it and take a stream with pipe ?

    song = subprocess.Popen(["ffmpeg.exe", "-i", sys.argv[1], "-f", "asetrate", "22050", "wav", "pipe:1"],
    
                        stdout=subprocess.PIPE)

  • How can I run an ffmpeg command in a python script ?

    24 juin 2022, par Nexion21

    I want to overlay a transparent video over top of an image using ffmpeg and python

    


    I am able to do this successfully through terminal, but I cannot get ffmpeg commands to work in python. The following command produces the result that I want in terminal when I am in the directory with the files there.

    


    ffmpeg -i head1.png -i hdmiSpitting.mov -filter_complex "[0:v][1:v] overlay=0:0" -pix_fmt yuv420p -:a copy output3.mov


    


    In python, my code is simple :

    


    import os
import subprocess
command = "ffmpeg -i head1.png -i hdmiSpitting.mov -filter_complex \"[0:v][1:v] overlay=0:0\" -pix_fmt yuv420p -c:a copy output3.mov"
subprocess.call(command,shell=True)


    


    The code runs, there is no indication of an error, but no output is produced.

    


    What am I missing here ?

    


  • Subprocess not working when called in atom

    22 août 2019, par jan1892

    I am running python3.6 in Atom using the package ’script’ on Ubuntu 18.04.

    I am trying to cut videos using ffpb (basically ffmpeg with a progress bar instead of verbose).

    The following code gives the error : ’FileNotFoundError : [Errno 2] No such file or directory : ’ffpb’ : ’ffpb’

    import subprocess
    

    
cmds = ['ffpb', '-i', 'input.mp4', 'output.mp4']
    
subprocess.call(cmds)
    • The command ’ffpb -i input.mp4 output.mp4’ works in the terminal
    • The script works when I call it with python3 in the terminal
    • The script works in atom if I replace ffpb by ffmpeg
    • I installed ffpb using pip3 install —user ffpb
    • I never had problems like this running code in atom before.

    Thanks in advance for any help.
