• ffmpeg creating MPEG Video slice code 01e0

  6 April 2014, by dinatis

  I have been using ffmpeg to encode some MPEG files (-vcodec mpeg1video), but at the end of the first slice, I see the code 01e0. The decoder implementation I am using is expecting a code in the range 0101 - 01af. So when 01e0 is encountered, the decoder thinks there are no more slices, pictures or GOP's.

  Does anyone what the 01e0 code signifies and what ffmpeg options I should use to get the slice codes (if that is what they are) appearing in the expected range?

• what is ffmpeg exit code 2? and also output error array is empty and not working in php

  14 June 2019, by Mehdi Zamani

  I use ffmpeg to convert bitrate to 128 but not working in php

   exec("ffmpeg -i input.mp3 -codec:a libmp3lame -b:a 128k output().mp3 2>&1", 
  
   $output, $exit_code);
  
   if ($exit_code!= 0) {
  
      $data['message'][] = "Error";
  
   }
  
  
  
   print_r($output);
  
   print_r($exit_code);
  
   exit;

  After running this code show error code 2.
  The output is an empty array and also exit_code is 2 and not create output.mp3 file.

  I already study How can I find out what this ffmpeg error code means? but this isn’t my problem and don’t explain error code 2 or error code 2 is not defined. My problem is dont show any error and error message is empty just exit_code show 2 that means is some error happened.

  I want to save thumbnails in my website using this simple FFMPEG code.
  I tried to run it, but it shows error

      <?php
  
  
  
  
  
  $file="Videos/bloodshot.mp4";
  
  $vname="bloodshot";
  
  
  
  $W = intval($_GET['file']);
  
  $H = intval($_GET['file']);
  
  
  
  if(substr($file,0,1) != '.'){
  
  
  
  $mov = new ffmpeg_movie($file);
  
  $wn = $mov->GetFrameWidth();
  
  $hn = $mov->GetFrameHeight();
  
  
  
  $frame = $mov->getFrame(32);
  
  
  
  $gd = $frame->toGDImage();
  
  
  
  if(!$W and !$H)
  
  {
  
  
  
  $W = $neww; // width of the image
  
  $H = $newh; // height image
  
  }
  
  
  
  
  
  $new = imageCreateTrueColor($W, $H);
  
  imageCopyResized($new, $gd, 0, 0, 0, 0, $neww, $newh, $wn, $hn);
  
  $black = imagecolorallocate($new, 255, 255, 255);
  
  imagegif($new);
  
  imagegif ($new, './thumb/success.gif', 100);
  
  }
  
  ?>

  error log is

  [25-Mar-2020 14:52:31 UTC] PHP Fatal error:  Uncaught Error: Class 'ffmpeg_movie' not found in /home/xxxxxxx/public_html/Videos/ffmpeg.php:12
  
  Stack trace:
  
  #0 {main}
  
    thrown in /home/xxxxxxx/public_html/Videos/ffmpeg.php on line 12

  I was able to run it without error in a mobile site few years ago. But it seems to be not working now.
  Server has FFMPEG support.
  I am not an expert in php, please fix this code for me.
