• using file info from txt file to bull trim audio with ffmpeg

  26 juin 2018, par thirtylightbulbs

  I have found how to trim individual audio files with ffmpeg. Is there any way to do it on bulk ? I have thousands of audio files each with different segments that need to be saved separately. The input file, time to start clipping, and duration are all in separate columns, row by row, in a text/excel file.

• I am trying to use ffmpeg to separate audio from video, but after downloading the ffmpeg build I cannot seem to activate it in Power Shell [duplicate]

  19 janvier 2021, par Row Boater

  Ok, look y'all, I am NOT an aspiring programmer. I'm simply trying to separate audio from video of a youtube video I downloaded.

  


  What I've done :

  


  Downloaded YT vid using 4k video Downloader

  


  I downloaded ffmpeg build from https://ffmpeg.org/download.html#build-windows

  


  I downloaded WinZip in order to access the ffmpeg files.

  


  I thought I used winzip correctly, but whenever I paste the command code line recommended to me, ffmpeg -i video.mp4 -c:a pcm_s16le audio.wav, I receive the following :

  


  


  PS C :\Users\user\Videos\4K Video Downloader> ffmpeg -i video.mp4 -c:a
pcm_s16le audio.wav ffmpeg : The term 'ffmpeg' is not recognized as
the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that
the path is correct and try again. At line:1 char:1

  


  

  • ffmpeg -i video.mp4 -c:a pcm_s16le audio.wav

  


  • 


      + CategoryInfo          : ObjectNotFound: (ffmpeg:String) [], CommandNotFoundException
  + FullyQualifiedErrorId : CommandNotFoundException



    


  


  


  PS C :\Users\user\Videos\4K Video Downloader>

  


  


  This is all Phoenician to me, but what I take away is that I have not completed some step to fully incorporate the ffmpeg code into my system. I believe that I am not using Winzip correctly.

  


  Thanks for your time.

  


• MoviePY error when running in Docker Container using Amazon Elastic Container Service

  27 mai 2023, par Giba

  I'm developing a script that generates a video with the information provided by the user using Moviepy. The application runs in a docker container.

  


  In my test environment (locally) the application usually runs generating the videos as expected. However, when I deploy to the Amazon Elastic Container Instance environment, the application renders the following error :

  


  /tmp/334.mp31boi_q7b: Invalid data found when processing input
Here are the file infos returned by ffmpeg:

OSError: MoviePy error: failed to read the duration of file /tmp/334.mp31boi_q7b.


  


  To retrieve files sent by the user, I use tempfile.NamedTemporaryFile and manipulate them in memory. I make some slices in the audio to synchronize with images (as if they were slides) and to concatenate them I use the following :

  


  audio_concat = concatenate_audioclips(audio_clips)


  


  and at the end, I generate the video as follows :

  


  with tempfile.NamedTemporaryFile(prefix=video_path, suffix='', delete=False) as data:
    video.write_videofile(data.name, fps=24, codec="libx264", ffmpeg_params=['-f', 'mp4'], threads=multiprocessing.cpu_count())


  


  As said, everything works fine in the container locally, but the same does not happen in ECS.

  


  Does anyone have any idea what I might be doing wrong ?

  


  My Dockerfile

  


  FROM ubuntu:latest
ENV DEBIAN_FRONTEND noninteractive

EXPOSE 8003

CMD ["uvicorn", "video_composer:app", "--proxy-headers", "--host", "0.0.0.0", "--port", "8003"]


  


  Some solutions consulted and no success

  


  Moviepy unable to read duration of file

  When trying to execute the mentioned solutions I continued to have the same error in the ECS but without errors locally.
