• ffmpeg error when I changed the server

  5 octobre 2012, par NewPHP

  I am changing someone's working site "video.net"(an example) from one server to another.
  But I am getting an error like :

  Warning : require_once(ffmpeg/movie.php) [function.require-once] : failed to open stream : No such file or directory in /store/websites/dvb/video.net/642/include/config.php on line 7.

  Fatal error : require_once() [function.require] : Failed opening required 'ffmpeg/movie.php' (include_path='. :/usr/share/pear :/usr/share/php') in /store/websites/dvb/video.net/642/include/config.php on line 7

  The error lines are below.

    function __autoload ($className)
  
    {
  
        $className = explode("_", $className);
  
        $className = implode("/", $className);
  
        require_once ("{$className}.php");
  
     }

  I haven't used ffmpeg before. Also I am new to it. Do you guys have any idea, what do I want to check ? I hope this is probably some installation error or something like that.

  Thanks !

• FFmpeg drawtext support for Hindi fonts

  28 février 2024, par Vinoth Poovalingam

  We are trying to use FFmpeg drawtext to support Hindi fonts. But the ordering of the data is not correct.

  


  The unicode for Hindi text is passed like this

  


  1. पिता माता िस्रफ


  


  But output renders as

  


  

  


  Have used the following code for generating the output

  


  ffmpeg  -framerate 30 -t 10 -i /opt/test.png drawtext=text_shaping=1:fontcolor=white:fontsize=60:fontfile=/usr/share/xx.ttf:text='1. पिता माता िस्रफ':y='max(550,700-t*200)':x=40,format=yuv420p[v] /usr/share/nginx/html/hello_v.mp4


  


  Had done harfbuzz support and --libfribidi is also enabled.

  


  The problem is the text gets drawn from left to right. Also found there is a use_kerning flag in drawtext, will that help, if yes how to use it.

  


• php_ffmpeg extension installed, want to know available classes in this extension [on hold]

  25 septembre 2013, par user2808180

  I have successfully installed the php extension "php_ffmpeg" and it is working fine. I tested the extension with class ffmpeg_movie and It shows me complete information of the file.

  But the problem is to convert any uploaded video file to flv. Is there any classes available in the extension 'php_ffmpeg', I would like you to share some sample code for that.

  I will like to stick to php code as I am not sure that I might not get access to the share server shell.

  I also tried exec, on my Windows Based local machine, but I haven't found success beyond "DIR" command.

  Please if you have some knowledge about "php_ffmpeg" extension and classes available in it, with example code or know some resource which include that please help me.

  $return = 1;
  
  $output = array();
  
  
  
  $source = $_SERVER['DOCUMENT_ROOT'] . '/sample.avi';
  
  $target = $_SERVER['DOCUMENT_ROOT'] . '/target.flv';
  
  
  
  
  
  $cmd = "ffmpeg -i {$source} {$target}";
  
  
  
  exec($cmd, $output, $return);
  
  
  
  
  
  echo &#39;<pre>&#39;; print_r($output); echo &#39;</pre>&#39;;
  
  
  
  echo $cmd;
