• ffmpeg with frei0r libraries fails on os x 10.14.6

  13 novembre 2019, par Bernhard Wagner

  I’m on Mac OS X 10.14.6 (Mojave), used homebrew to install both ffmpeg and frei0r.
  If you check the output below, the option --enable-frei0r is there.

  I verified the path to the frei0r libaries and call ffmpeg like this :

  FREI0R_PATH=/usr/local/Cellar/frei0r/1.6.1/lib/frei0r-1/ ffmpeg -v debug -i running.mkv -filter:v frei0r=pixeliz0r=0.02:0.02 pixel.mkv

  however it fails the exact same way as if I hadn’t passed the env var FREI0R_PATH :

  FREI0R_PATH=/usr/local/Cellar/frei0r/1.6.1/lib/frei0r-1/ ffmpeg -y -v debug -i running.mkv -filter:v frei0r=pixeliz0r=0.02:0.02 pixel.mkv

  I am writing a Python script to convert a video (.MP4) into an audio file (.MP3) on a Django server. To achieve this, I am using the Moviepy library but when I run the script, I get the following error :
