  ffmpeg : remove ffmpeg_videotoolbox
  This was almost completely redundant. The only functionality that's no longer
  
  available after this removal is the videotoolbox_pixfmt arg, which has been
  
  obsolete for several years.

• FFMPEG is throwing Not enough memory resources on Azure VM [closed]

  20 août 2021, par Gaurav

  I have 500 MB video file which I am converting to MP4 format.

  


  My laptop is i7 and 16 GB Memory and ffmpeg is able to convert the file.
Command used is as follows :

  


  ffmpeg.exe -i  "a.mp4" -c:v  libx264  -crf  35  -preset  ultrafast  "b.mp4"


  


  On Azure , I have D series machine with 8 core and 32 GB. Memory used is 14% only. at this time, when I run this command , after certain time I get following error.

  


  Is there any other fine tuning required on azure VM ?

  


  out:

  used until now.
