• FFMPEG show encoding progress

  18 janvier 2016, par Mick Jack

  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 />";
  
              echo "Current Time: " . $time . "<br />";
  
              echo "Progress: " . $progress . "%";
  
  
  
  }

  Explicit deinitialization of progress listeners.
  This addresses a memory leak with Microsoft Edge.
  Thanks @butonic for the report, investigation and fix.

• The progress bar preview of an MP4 video becomes a scary image

  4 juillet 2021, par treblez

  When I opened the video progress bar at 1:00 last night, the preview looked like this
I used the ffmpeg -I command to extract the video frame by frame and did not find this image
The progress bar preview returned to normal this morning, and the system time changed after the network was cut off was still normal until 1:00 a.m
I have no experience in video processing. How can I find this image ?
