          $file = pathinfo($name,PATHINFO_FILENAME); 
  
          $extension = pathinfo($name,PATHINFO_EXTENSION);
  
  
  
          $ffmpeg = \FFMpeg\FFMpeg::create([

          ]);
  
          $video = $ffmpeg->open($url);
  
          $format = new FFMpeg\Format\Video\X264('libmp3lame', 'libx264');
  
          $format->on('progress', function ($video, $format, $percentage) {

• What is video timescale, timebase, or timestamp in ffmpeg ?

  28 février 2020, par Please Help

  There does not seem to be any explanation online as to what these are. People talk about them a lot. I just want to know what they are and why they are significant. Using -video_track_timescale, how would I determine a number for it ? Is it random ? Should it be 0 ?
