              preg_match("/Duration: (.*?), start:/", $content, $matches);
  
  
  
              $rawDuration = $matches[1];
  
  
  
              //rawDuration is in 00:00:00.00 format. This converts it to seconds.
  
              $ar = array_reverse(explode(":", $rawDuration));
  
              $duration = floatval($ar[0]);
  
              if (!empty($ar[1])) $duration += intval($ar[1]) * 60;
  
              if (!empty($ar[2])) $duration += intval($ar[2]) * 60 * 60;
  
  
  
              //get the time in the file that is already encoded
  
              preg_match_all("/time=(.*?) bitrate/", $content, $matches);
  
  
  
              $rawTime = array_pop($matches);
  
  
  
              //this is needed if there is more than one match
  
              if (is_array($rawTime)){$rawTime = array_pop($rawTime);}
  
  
  
              //rawTime is in 00:00:00.00 format. This converts it to seconds.
  
              $ar = array_reverse(explode(":", $rawTime));
  
              $time = floatval($ar[0]);

              if (!empty($ar[2])) $time += intval($ar[2]) * 60 * 60;
  
  
  
              //calculate the progress
  
              $progress = round(($time/$duration) * 100);

• Sample player that shows ffmpeg libstagefright.cpp usage

  24 février 2014, par Mayank Agarwal

  I am trying to write ffmpeg and OMXIL based mediaplayer.Facing issues in compiling the code with so many header files and libraries to include for android media framework.
  Is there any sample player that uses ffmpeg libstagefright.cpp so that i can understand its usage and base my player on that.

  Regards
