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

  14 juin 2019, par 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.

• ffmpeg creating MPEG Video slice code 01e0

  6 avril 2014, par 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 ?

• PHP and FFMPEG Remove Code in Video [on hold]

  6 janvier 2015, par user580950

  I have set of videos where i need to remove the code ( check below screen grab as an example ), you can see the code in RED .NOt sure if its possible to do it using PHP & ffmpeg or similar to detect a black box or hash key or serial no and blur out.

  It must be able to use mpeg-ts file input and output with mpeg-ts.

  Detection must be done and blurring must start 5 (configurable) seconds before the black box appears, this means we have to buffer the video and blur out the position where it will appear before it does.
