• Get subdirectory name in bat FOR /R loop and name file accordingly

  23 février 2021, par CatTheGrimReaper

  I know this question sounds like a duplicate, but I couldn't find an answer in all the similar questions.
I have this code in a .bat file :

  


    for /R "C:\Users\XX\XXX\XXXX\XY" %%F in (*.m*) do (
    ffmpeg -i %%F -vf "setpts=N/TB,fps=1,select=not(mod(n\,29)), crop=min(in_w\,in_h):min(in_w\,in_h), scale=1024:1024" -vsync 0 -frame_pts 1 -f image2 %%F-"frame-"%%3d.jpg
    )


  


  Which takes every video file in the given path (C :\Users\XX\XXX\XXXX\XY), splits it into frames (every 29th frame) and saves those frames as "FILENAME-frame-FRAMENUMBER". This works very well, but I'd like to name the file "SUBDIRECTORY-frame-FRAMENUMBER". Is this possible ? Every answer I read had the subdirectory name as its own variable (so in my case in place of the %%F), but I need that %%F to modify each file with FFMPEG.

  


  I appreciate any help ! Thanks in advance.

  


• 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

  Some solutions consulted and no success

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