  mov : Fix handling of zero-length metadata values
  Since 3cec81f4d4, a zero-length metadata value would try to
  
  allocate 2*0 bytes, where av_malloc() returns NULL.
  Always add one to the allocated length, to allow space for
  
  a null terminator in the zero-length case.
  Incidentally, this fixes fate-alac on RVCT 4.0, where a compiler
  
  bug seems to mess up the mov muxer to the point that it writes
  
  the wrong sort of metadata. Previously this bug was undetected,
  
  but since 3cec81f4d4 such mov files started returning
  
  AVERROR(ENOMEM) in the mov demuxer.

• 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

  


  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

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.
