  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 />";

• Paperclip Video Skewed (does not maintain aspect ratio)

  3 septembre 2015, par zreitano

  The video uploaded does not maintain aspect ratio. In the readme (paperclip av-transcoder) it says, " ’ !’ - Keep the same aspect of the image/video, but with the passed dimension." I have also tried the other options(<># !) and none of them effect the size of the video.

  My goal is to be able to be able to have the video returned in a square (while maintaining the aspect ratio). Cropping from the center would be ideal, as well.

  Any help would be greatly appreciated. I included my code below.

  class Video < Post
  
  
  
    Paperclip.interpolates :id do |attachment, style|
  
      attachment.instance.id
  
    end
  
  
  
    #basename/extension is paperclip interpolation from attachment, can write own interpolations as needed
  
  
  
    # have to link /usr/local/bin to the linuxbrew version of ffmpeg
  
    has_attached_file :video,  path: "/posts/videos/:id/:style.:extension",
  
    :styles => {
  
      :square => {:geometry => "500x500!", :format => 'mp4', :streaming => true }
  
    },
  
    :processors => [:transcoder]
  
  
  
    validates_attachment :video, :presence => true,
  
                             :content_type => { content_type: ["video/mp4", "video/mov", "video/mpeg","video/mpeg4", "video/quicktime"] }
  
  
  
    def video_url
  
      video = self.video
  
      if video.present?
  
        return video.url(:square)
  
      end
  
    end
  
  
  
  end
