• 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

WORKDIR /video_composer

COPY requirements.txt /video_composer/requirements.txt

RUN apt-get update && apt-get install -y software-properties-common gcc && \
    add-apt-repository -y ppa:deadsnakes/ppa

RUN apt-get update && apt-get install -y python3.11 python3-distutils python3-pip python3-apt

RUN apt-get install -y ffmpeg

RUN pip install -r /video_composer/requirements.txt

RUN python3 -m certifi

COPY . /video_composer/

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.

  


• Why is this video file not supported in mobile safari ?

  30 septembre 2015, par pinkboi

  I’m using libffmpeg to generate my video and it’s playable on desktop browsers and many other places (including android). I looked at this earlier post, and the linked-to Apple guidelines but nothing stuck out at me as wrong about my stream. Are only certain framerates supported ? Here is the output of ffprobe -show_streams on a generated file :
