  Is there any way to execute it faster ? Or maybe I have to use gpu to proceed it faster ? Any ideas ? I execute it very often and any shortening time would be great.

  


  I read about hardware acceleration, but I am not sure if it will help. It is possible also to upgrade version of ffpmeg, but will it help ?

  


• Files gets corrupted after resizing with ffmpeg

  26 octobre 2018, par Liam

  I’m making a bot that sends videos to instagram. However instagram only allows 1:1 aspect ratio videos, so I’m trying to use ffmpeg in python (ffmpy module) to resize the video (.mp4) file.

  This is the ffmpeg code I’m using
  -analyzeduration 20M -probesize 20M -y -i FILE.MP4 -vf "scale=1080:1080:force_original_aspect_ratio=decrease,pad=1080:1080:(ow-iw)/2:(oh-ih)/2:white NEW_FILE.MP4

  However this corrupts the file ? The size of the file before resizing is 1.815305 MB but after the ffmpeg job it’s 0.058714 MB. So what gives ?

  (I also tried using -aspect 1:1 but that corrupts the file too)

  Ffmpy seems to work fine, because sometimes if the file is over 20 MB i run this to reduce the file size -y -i FILE.MP4 -vcodec libx264 -crf 24 NEW_FILE.MP4 and that works fine.

  Here’s the full log if needed :
