• 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

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

  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.

  


• install ffmpeg on amazon ecr linux python

  27 mai 2024, par Luka Savic

  I'm trying to install ffmpeg on docker for amazon lambda function.
Code for Dockerfile is :

  


  FROM public.ecr.aws/lambda/python:3.8

# Copy function code
COPY app.py ${LAMBDA_TASK_ROOT}

# Install the function's dependencies using file requirements.txt
# from your project folder.

COPY requirements.txt  .
RUN  yum install gcc -y
RUN  pip3 install -r requirements.txt --target "${LAMBDA_TASK_ROOT}"
RUN  yum install -y ffmpeg

# Set the CMD to your handler (could also be done as a parameter override outside of the Dockerfile)
CMD [ "app.handler" ]


  


  I am getting an error :

  


   > [6/6] RUN  yum install -y ffmpeg:
#9 0.538 Loaded plugins: ovl
#9 1.814 No package ffmpeg available.
#9 1.843 Error: Nothing to do


  


• Amazon S3 : how to combine all images into a video ?

  9 septembre 2021, par scientiffic

  I'm in my Rails app, I enable users to upload images, which get processed using ffmpeg to create a video slideshow.

  



  I have this working locally, but am wondering how to do this when deploying the app using Heroku. In particular, I know Heroku has limited storage and has a read-only filesystem, so using Carrierwave without S3 or an external storage option doesn't seem like an option.

  



  But how would I run a task like the following using S3, where I combine all images into a video ?

  



  The ffmpeg command is

  



  ffmpeg -r 5 -i https://s3.amazonaws.com/[]/uploads/image/image_file/26/img%03d.jpg output.mp4 -y


  



  And the AWS "folder" contains the following :
https://s3.amazonaws.com/[]/uploads/image/image_file/26/img001.jpg
https://s3.amazonaws.com/[]/uploads/image/image_file/26/img002.jpg
https://s3.amazonaws.com/[]/uploads/image/image_file/26/img003.jpg

  



  When I try to do the following, I get an error with ffmpeg not knowing what to do with :

  



  https://s3.amazonaws.com/[]/uploads/image/image_file/26/img%03d.jpg


  



  Note, this whole video compilation process works fine for me locally, so I know in theory it should work.
