  • Can't save a file in moviepy python

    23 juillet 2023, par user9102437

    I have seen a few questions about this here, but none of them solved the issue for me, so maybe my case is different in some way.

    


    I am trying to achieve a simple result : read a file and write it. Here is the code :

    


    import os
os.environ['FFMPEG_BINARY'] = '/usr/bin/ffmpeg'

from moviepy.editor import VideoFileClip
name = 'test.mp4'

clip = VideoFileClip('./vids/'+name)

clip.write_videofile('./vids/'+name, codec='libx264', fps=30)


    


    This code comes up with an error :

    


    ---> 88     '-r', '%.02f' % fps,
     89     '-an', '-i', '-'
     90 ]
     91 if audiofile is not None:
     92     cmd.extend([
     93         '-i', audiofile,
     94         '-acodec', 'copy'
     95     ])

TypeError: must be real number, not NoneType


    


    You may notice that I have set the environment variable for ffmpeg (I have also changed that in configure_defaults.py). This is because it was suggested in other questions. Also based on them I have run the following commands before running the code :

    


    sudo apt -y update
sudo apt -y install ffmpeg
pip install decorator
pip install moviepy --upgrade
pip install ffmpeg --upgrade


    


    I am using a Debian GNU/Linux 10 (buster) machine, and the versions of moviepy and ffmpeg are 1.0.3 and 4.1.10-0+deb10u1 respectively.

    


    Nothing seems to be helping to solve this. What am I missing here ?

    


  • Can't figure out how to get ffmpeg to save to an odd file extension

    30 septembre 2015, par dinki

    I’m working on a network encoder for SageTV. I get request from the SageTV with certain filenames. I’m trying to capture video from my capture card and write out to a file called

    ’D :\Media\tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-
    0.mpgbuf’

    Here’s the command I’m using :

    C :\Users\User>C :/Users/User/Desktop/ffmpeg-20150928-git-235381e-win64-static/bin/ffmpeg.exe
    -f dshow -crossbar_video_input_pin_number 2 -i video="ATI AVStream Analog Capture"
    D :\Media\tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-0.mpgbuf

    When I run that command, I get this error :

    [NULL @ 00000000087f9160] Unable to find a suitable output format for 'D:\Media\
    
tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-0.mpgbuf'
    
D:\Media\tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-0.mpgbuf: Invalid
    
 argument

    But if I change .mpgbuf to .mpg it works fine . I am forced to use that filename though. Is there an easy way to do this ?

  • How to save frames to the video using their timestamps (variable frame rate, vfr, PyAV)

    9 juillet 2019, par Vladyslav Moisieienkov

    Shorty, I would like to write frames to the video according to their timestamps. FFmpeg example could be found here - How do I render a video from a list of time-stamped images ? , and I need something like that in Python. Probably PyAV library should be used as it provides bindings for FFmpeg. Maybe, it also possible by using OpenCV.
