  so i ask some one he told me the exec stop php script and never give me

  You can't get the progress directly if you are using exec, because the php script is stopped until ffmpeg closes. (Because exec returns the whole execution output)
  
  
  
  You should use popen, for being able to get the output from the process in real time (without reading any file) for parse and show the progressbar
  
  
  
  Here is a example for get the output: 
  
  
  
  When you get the progress info from ffmpeg, you can use your code for parse it and show your progressbar

  this is my popen script

  <?php 
  
  
  
  $handle = popen ("ffmpeg.exe -i files/fz.mp4 -ab 192k files/vdf.mp3 2>&1 ", 'r');
  
  $handles = (string)$handle;
  
  $line = "";
  
  
  
  while (false !== ($char = fgetc($handle)))
  
  {
  
    if ($char == "\r")
  
    {
  
      // You could now parse the $line for status information.
  
      echo "$line\n";
  
      $line = "";
  
    } else {
  
      $line .= $char;
  
    }
  
    ob_flush();
  
    flush();
  
  }
  
  pclose ($handle);
  
  
  
  
  
      //get duration of source
  
      preg_match("/Duration: (.*?), start:/", $handles, $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/", $handles, $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[1])) $time += intval($ar[1]) * 60;
  
      if (!empty($ar[2])) $time += intval($ar[2]) * 60 * 60;
  
  
  
      //calculate the progress
  
      $progress = round(($time/$duration) * 100);
  
  
  
  
  
  
  
  
  
      echo '<br /><br />¡Su video fue convertido correctamente! <br /><br />Link al archivo:';
  
  
  
  
  
      echo "Duration: " . $duration . "<br />";
  
      echo "Current Time: " . $time . "<br />";
  
      echo "Progress: " . $progress . "%" . "<br />";

• Choose good solution for streaming video in android [closed]

  28 novembre 2013, par Alex Tran

  I always find solution for fixing this bug

  "Invalid streaming" or "Can not play video"

  on many devices.

  I researched and found many people get this bug.

  There are two solutions :

  1. At Server side : Convert to appropriate "h264 avc baseline + web optimized *.mp4" format for Android device can stream & play video.

  2. At Android side : Use third-party library to fix :

     • VitamioBundle : I tested on many devices,
       some devices (Android version 4.0.3 or above, and have StageFright
       framework) stream & play video very good, but the others (before
       Android version 4.0) is not . I think the framework on the device causes it. (related to OpenCore/StageFright framework)

     • Ffmpeg : I researched about Android NDK. And know how to build to file *.so.

  Actually, I can not edit at server side.

  Can I use ffmpeg in second solution ?

  But I don't really know it is the good way or not ?

  p/s : Actually, I want to stream and play video from the server on all devices have version from Froyo 2.2.

  Please tell me,

  Regards,
