• How to setup ffmpeg for CentOS release 6.5 server

  23 juillet 2015, par hitesh

  I need to create a screen shot from video,

  I have followed this tutorial to do the intial setup in window 8, php 5.3

  1) I downloaded the ffmpeg from here -[
  http://ffmpeg.zeranoe.com/builds/ ] for 64 bit operating system.

  2) I followed the https://www.youtube.com/watch?v=gU49GiWGGAI , video and did all configuration successfully and phpinfo() shows that ffmpeg has been installed.

  3) Then I tried this to find out whether it is working or not,

  It worked successfully

  4) Next I followed this video tutorial here and thumbnails were created successfully.

  below is my code

  /**
  
   * FFMPEG-PHP Test Script
  
   *
  
   * Special thanks to http://www.sajithmr.me/ffmpeg-sample-code for this code example!
  
   * See the tutorial at http://myownhomeserver.com on how to install ffmpeg-php.

  error_reporting(E_ALL ^ E_NOTICE);
  
  // Check if the ffmpeg-php extension is loaded first
  
  extension_loaded('ffmpeg') or die('Error in loading ffmpeg');
  
  
  
  // Determine the full path for our video
  
  $vid = realpath('./videos/myvideo.mp4');
  
  $videosize = filesize($vid);
  
  $remoteVideo = 'http://video-js.zencoder.com/oceans-clip.mp4';
  
  
  
  //ffmpeg
  
  
  
  $ffmpeg = dirname(__FILE__) . "\\ffmpeg\\bin\\ffmpeg";
  
  $imageFile = "1.png";
  
  $image2 = "2.png";
  
  $size = "120x90";
  
  $getfromsecond = 7;
  
  $cmd = "$ffmpeg -i $vid -an -ss $getfromsecond -s $size $imageFile";
  
  $cmd2 = "$ffmpeg -i $remoteVideo -an -ss $getfromsecond -s $size $image2";
  
  if(!shell_exec($cmd)){
  
      echo "Thumbnail created";
  
  }else{
  
      echo "Error Creating thumbnail";
  
  }
  
  
  
  if(!shell_exec($cmd2)){
  
      echo "Thumbnail for remote url was created";
  
  }else{
  
      echo "Error Creating thumbnail for remote url ";
  
  }

  ---

    OUTPUT
  
      Thumbnail created
  
      Thumbnail for remote url was created

  Now above code works as expected in my local, in window machine , I need to do it in my server environment(Linux server) with php 5.5. How do I do the configuration for ffmpeg in CentOS release 6.5 server with php 5.5.

  But in server when I open my php file I am getting this error Error in loading ffmpeg

  Also I have checked phpinfo(), It shows ffmpeg installed in my local but not in server.

  What else I need to do to configure ffmpeg in Cent Os 6.5 php 5.5.

• Is Electron using a custom-licensed libx264 variant ?

  13 septembre 2016, par JohnW

  Electron is providing a few variants of FFmpeg.

  The variant I have seems to handle H264 just fine, which it does using libx264 apparently.

  The question is simple : Do electron developers have a special deal with VideoLan to provide an MIT licensed FFmpeg with x264 ?

  I am asking because VideoLan seems to dual-license libx264 (GPL and custom license) so it is possible that there is a deal.

  According to this link however the answer may very well be "no".
