• How do I fix my ffmpeg command to stop the Terminal from hanging ?

  29 juillet 2017, par ksy

  I am attempting to use ffmpeg to concatenate video files together into a single file, video/video_after.mp4.

  I ran different tests of video length, and it seems the issue isn’t correlated with the duration of the video.

  When I run the following command, my terminal hangs and the operation never completes — ss there something wrong with the command I am running here ?

  ffmpeg -i video/video_after0.mp4 -i video/video_after1.mp4 -i video/video_after2.mp4 -i video/video_after3.mp4 -i video/video_after4.mp4 -i video/video_after5.mp4 -i video/video_after6.mp4 -i video/video_after7.mp4 -i video/video_after8.mp4 -i video/video_after9.mp4 -i video/video_after10.mp4 -i video/video_after11.mp4 -i video/video_after12.mp4 -i video/video_after13.mp4 -i video/video_after14.mp4 -i video/video_after15.mp4 -i video/video_after16.mp4 -i video/video_after17.mp4 -i video/video_after18.mp4 -i video/video_after19.mp4 -i video/video_after20.mp4 -f concat -safe 0 -i video/video_after21.mp4 -y -c copy video/video_after.mp4

• Command works in SSH terminal, but not in PHP script

  13 janvier 2017, par Ryan Butterworth

  I’m having a weird problem. I have installed ffmpeg on my server. When I run "ffmpeg" from SSH (PuTTY) it confirms the install :

  

  Then I placed the following code in a PHP file, inside a website on the same server :

  <?php
  
  ini_set('display_errors', 1);
  
  ini_set('display_startup_errors', 1);
  
  error_reporting(E_ALL);
  
  
  
  $output = exec('ffmpeg -h');
  
  echo "<pre>$output</pre>";
  
  ?>

  However when I run the PHP script, the page is blank, there is no output. I can confirm that exec is working fine, because when I run php -v | grep cli both in PHP and in terminal, they both output the same thing.

  I am using Plesk (web host edition) to manage the site, and have given it access to the server over SSH (/bin/sh)

  What am I missing here ?

• FFMPEG command fails in php but runs in terminal [closed]

  13 juillet 2021, par victor ukafor

  I'm writting some logic that requires video manipulation, each time i try to run ffmpeg command with Process (or some other php in-built function for running shell command), the command fails with WARNING : library configuration mismatch but it runs without any warning on my terminal. Some tutorials suggest I unistall libavcodec-ffmpeg-extra56 or libavcodec-ffmpeg-extra57 on machine. I have done that still no changes.
