• MAINTAINERS : Add Haihao Xiang for vaapi

  MAINTAINERS : Add Haihao Xiang for vaapi
  Current listed maintainers for vaapi plugin are
  
  not reponsive and/or currently active in the
  
  ffmpeg community.  Thus, vaapi plugin patches
  
  (and qsv plugin) have generally gone ignored or
  
  lost in the ether for too long.
  Remove Gwenole Beauchesne from vaapi maintainer
  
  who has not been active since 2016.
  Current alternative maintainer for vaapi is Mark
  
  Thompson whom has not been active since
  
  March/April 2021.
  Therefore, add Haihao Xiang to vaapi maintainer
  
  who's primary role is FFmpeg development with a
  
  focus on the vaapi and qsv plugins.  Haihao has
  
  over a decade of media experience and many years
  
  of FFmpeg development experience, amongst other
  
  media frameworks.
  The additional patch for adding Haihao as qsv
  
  plugin maintainer has been submitted previously :
  https://patchwork.ffmpeg.org/project/ffmpeg/patch/20210608141134.27448-1-zhongli_dev@126.com/
  This will help FFmpeg to continue to be the leading
  
  multimedia framework by allowing these plugins to be
  
  actively improved, enhanced, and maintained for existing
  
  and future HW platforms.

• 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 :

• How to use Audio Segment Library on Heroku ?

  24 septembre 2021, par Lara Saka

  Audio Segment Library requires ffmpeg or avconv I installed ffmpeg.exe and
add it in the Enivronment Variables->PATH on my computer then, I run the project locally it works very well.
But When I deployed the same python project on heroku Audio Segment doesn't works because it needs ffmpeg or avconv.

  


  Logs from my project on Heroku :

  


  


  2021-09-24T09:44:56.297246+00:00 app[worker.1] :
/app/.heroku/python/lib/python3.9/site packages/pydub/utils.py:170 :
RuntimeWarning : Couldn't find ffmpeg or avconv - defaulting to ffmpeg,
but may not work

  


  2021-09-24T09:44:56.297256+00:00 app[worker.1] : warn("Couldn't find ffmpeg or avconv - defaulting > to ffmpeg, but may not work", RuntimeWarning)

  


  


  How can I make it works on Heroku ?

  


  And very Thanks..
