• How to install ffmpeg on Google App Engine ?

  3 mai 2020, par UtkuBulkan

  I intend to install ffmpeg and ffprobe to my Google App Engine flex environment, how can I do this with requirements.txt as a package ?

  



  I am currently using ffmpeg-python yet, this is only a wrapper.

  



  ffmpeg-python==0.2.0
ffprobe-python==1.0.3


  



  Below is the error when I try to use ffmpeg-python wrapper, which is expected as there is no ffmpeg and ffprobe available :

  Can you please suggest a way, so I can use ffprobe on Google App Engine.
