• Split MPEG-1/2 decoder code off from MPEG-1/2 common code

  Split MPEG-1/2 decoder code off from MPEG-1/2 common code

• FFmpeg's common filter "v360" missing

  26 septembre 2021, par Niklas E.

  I'm trying to convert a 180° fisheye video to a normal/regular video using the v360 filter of FFmpeg.

  


  This is the command I tried :
  
ffmpeg -i in.mp4 -vf "v360=input=fisheye:output=flat:iv_fov=180:v_fov=90" out.mp4

  


  But the output says clearly No such filter: 'v360', although v360 is a common filter listed in docs and other filters I used before worked just fine. I tried updating/reinstalling and looking for solutions, not fixing it.

  


  Why is the filter missing ? How can I debug this ? Should I doe the task using another program entirely ?

  


  Command output :
