• How to install ffmpeg on Google App Engine ?

  1er avril 2024, par london_utku

  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.

  


• ffmpeg strftime no effect on windows

  18 mai 2020, par Ben

  I'm trying to auto mark the output file with timestamps with ffmpeg. Here's my test cmd :

  



  .\ffmpeg.exe -y -loglevel 99 -i test.mp3 -strftime 1 %Y.ogg


  



  I expected a file named 2020.ogg, however only got %Y.ogg. In another word, output filename is not processed by strftime(). I'm using powershell so there should be no relation with cmd's %% escaping.

  



  Here's the output : https://pastebin.com/LUVh2kFA I'm using static builds from https://ffmpeg.zeranoe.com (Thanks Zeranoe !) I confirmed that the problem exists in v4.2.2 and git-20200515. Is there any chance to fix it or am I doing it wrong ?
