• FFmpeg audio doesnt work in converted videos but in pc it does

  28 octobre 2013, par Dirk Swarz

  I use :

  if($ext == "avi" && $convert_avi == true)
  
                      {
  
                          $convert_source = _VIDEOS_DIR_PATH.$new_name;
  
                          $conv_name = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
  
                          $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
  
                          $ffmpeg_command = 'ffmpeg -i '.$convert_source.' -acodec libmp3lame -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$converted_file;
  
                          echo exec($ffmpeg_command);
  
                          $sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
  
                          $result = @mysql_query($sql);
  
                          unlink($convert_source);    
  
                      }

  This code to convert avi to mp4
  ffmpeg concole output :

• How to compress video size without changing much quality and without changing framerate (Ffmpeg) ?

  19 septembre 2020, par WebDiva

  I am using this command to compress my videos :

  


  ffmpeg -y -i video.mp4 -vcodec libx264 -crf 24 -preset ultrafast compressed.mp4



  


  Although it works okay, there is a slight increase in duration because I am changing the framerate of videos, and we need the video to be the exact duration. Is there a way to compress videos without changing the framerate ? any help would be appreciated. Thank you.

• FFMPEG doesn't work with mp4 and stdout

  22 septembre 2020, par Max Grigoriev

  I need to add text to mp4 video. If I write result to file then everything is OK, but I want to read data from ffmpeg stream.

  



  I run command :

  



  ffmpeg -i sample.mp4 -filter_complex "drawtext='text=\"Sample Text\"':x=(w-text_w)/2:y=(h-text_h-line_h)/2:fontsize=40:fontcolor=white:fontfile=TimesNewRoman.ttf:enable='between(t,1,5)'"  -f mp4 -


  



  I received the following error :

  It seems the problem is related to mp4 and "muxer does not support non seekable output"

  



  Is there a solution how to make such text adding on the fly and return video as we have data and not to wait until all file is processed.

  



  Thanks
