• Show Filename in Video (fmpeg - drawtext)

  3 mai 2017, par Niklas Wünsche

  right now, I want to add the filename of a video as text in the video itself. So if the video is in the file ’video2.mp4’, there should be ’video2’ written in the center of the video. How can I do this with drawtext ?

  I am using ffmpeg to convert a video file large files take a long time to get encode. i will like to show a progress bar with a percentage/time remaining

  i saw and tried this example example but progress bar is not showing

  FFMPEG script and autorefresh both in upload.php

      <?php
  
  shell_exec("C:\\ffmpeg\\bin\\ffmpeg.exe -y -i ".$target_file." -c:v libx264 -s:v 854x480 -c:a copy \"{$newFileName}\" > logfile.txt 2>&1");
  
  
  
           ?>
  
  
  
          <code class="echappe-js">&lt;script src=&quot;https://code.jquery.com/jquery-2.1.1.min.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt;
          
  &lt;script&gt;<br />
  
          $(document).ready(function(){<br />
  
          setInterval(function(){<br />
  
          $(&quot;#screen&quot;).load('progress.php')<br />
  
          }, 10000);<br />
  
          });<br />
  
          &lt;/script&gt;
  
  

  Progress.php

  <?php
  
  
  
  $content = @file_get_contents('logfile.txt');
  
  
  
              if($content){
  
              //get duration of source
  
              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[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 "Duration: " . $duration . "<br />";
