• catch percentage File conversion ffmpeg

  28 mai 2013, par offboard

  I've been thinking about implementing a new function on my system.
  so I thought to show the state of the file conversion.
  I thought of a logic to it.
  updating table from the database according to the percentage of file conversion.

  <?
  
  exec('ffmpeg -i p17prdvj251lk11d3v12ntijfq2u1.mp4 -vf scale=-1:360 -c:v libx264 -preset ultrafast output.flv');
  
  for($i = 0; $i <= 1; $i++){
  
      mysql_query("UPDATE progress SET pss='".$i."' WHERE id='1'");
  
  }

  the problem is that I do not know if it's possible to get the percentage.
  I thought about using the extension of ffmpeg and create a function to convert the files but do not know if it will work

    No zoom window size hints defined
  
  
  
    No window shape defined
  
    No border shape defined

  However, if I try capturing from the screen given the size and offset of the child window, then I risk losing data when another window floats ontop of it, I switch to another tab while recording, I resize the child window, or move the child window. Instead, I'd like to use ffmpeg to capture from specifically that child window.

  Ideas ? Tips ? Maybe some other hacks to accomplish this ? Thanks :)
