  Here is the command I entered :

  git clone --depth 1 git://source.ffmpeg.org/ffmpeg

  And this is the error message that popped up

  Initialized empty Git repository in /root/ffmpeg_sources/ffmpeg/.git/

• Accented characters are not recognized in python [closed]

  10 avril 2023, par CorAnna

  I have a problem in the python script, my script should put subtitles in a video given a srt file, this srt file is written by another script but in its script it replaces the accents and all the particular characters with a black square symbol with a question mark inside it... the problem I think lies in the writing of this file, what follows and that in overwriting the subtitles I do with ffmpeg the sentences that contain an accented word are not written

• avformat/img2dec : set r_frame_rate in addition to avg_frame_rate

  7 avril 2021, par Jan Ekström

  avformat/img2dec : set r_frame_rate in addition to avg_frame_rate
  Apparently for various image sequences libavformat/utils.c can
  
  calculate rather fancy r_frame_rate values, such as `186/1921`,
  
  and since ffmpeg.c utilizes r_frame_rate for the filter chain
  
  time base, this can quite deteriorate the output frame timing - even
  
  though the user has requested the image sequence to be interpreted
  
  at a specific, constant frame rate.
