• If I pass this code in Windows console it works, but when I emulate windows console in node.js code doesn't work, and returns unclear error

  22 décembre 2016, par Maxim Cherevatov

  I have code :

  cmd.get(
  
      'trimp3  ant.mp3 ant2.mp3 00:00 00:20',
  
      function(data){
  
          console.log('the node-cmd cloned dir contains these files :\n\n',data)
  
      }
  
  );

  If pass this code in Windows console it works well !
  But, when i emulate windows console in node.js this code not work, and returns unclear mistake :

  [!!] ERROR:  "ffmpeg" �� ����� ����७��� ��� ���譥�
  
  ��������, �ᯮ��塞�� �ணࠬ��� ��� �������� 䠩���.

  To emulate the use node-cmd.

• Read a Bytes image from Amazon Kinesis output in python

  14 février 2020, par Varun_Rathinam

  I used imageio.get_reader(BytesIO(a),  'ffmpeg') to load a bytes image and save it as normal image.

  But the below error throws when I read the image using imageio.get_reader(BytesIO(a),  'ffmpeg')

  The above approach to read a MKV bytes file was done based on this thread

  Or is there is any approach to parse and read the MKV bytes file.

• 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 ?

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