• FFMPEG on Fedora but PHP Compilation confliction

  11 octobre 2013, par UMI

  I have running Xampp with PHP5.5 on Fedora from Apache Friend, with default settings what the installer package do on Linux.

  When I install FFMPEG successfully and try to load from php.ini it always says :

  *

  11-Oct-2013 14:05:51 Europe/Berlin] PHP Warning:  PHP Startup: ffmpeg: Unable to initialize module
  
  Module compiled with module API=20060613
  
  PHP    compiled with module API=20121212
  
  These options need to match
  
  in Unknown on line 0

  *

  The only thing which is confusing me is that when I did phpize even that I already installed xampp server which means I have PHP running. FFMPEG phpize did not work and I had to install php-devel. Does that mean that FFMPEG is configured with PHP, other than the installed with XAMPP ? I am not sure what is happening. Whatever I do I always receive this error message in php_error_log file.

  It is amazing :) that I just run below command to see what version of PHP is, I have and below are the results which are shocking one because I am in a feeling that I have PHP 5.5 installed and running from XAMMP.

  [root@localhost ~]# php -v
  
  PHP 5.2.6 (cli) (built: May  8 2008 08:53:44)
  
  Copyright (c) 1997-2008 The PHP Group

  How can I get this covered that if I simple install XAMPP server on linux and want to install and configure FFMPEG along with ?

• ffmpeg command and args execute successfully with child_process.exec() but not child_process.spawn()

  15 octobre 2013, par Zugwalt

  I am trying to use ffmpeg to add text to a video via the drawtext filter from within node.js in a windows environment.

  I have a command and arguments that work in the command line and when executed using the child_process module's exec function, but it encounters an error when the same arguments are used with the spawn function.

  The below code illustrates the problem :

  var child_process = require('child_process');
  
  
  
  var cmd = 'ffmpeg';
  
  
  
  var args = [ '-i',
  
               'c:\\path\\to\\my\\inputfile.mp4',
  
               '-vf',
  
               'drawtext="fontfile=/Windows/Fonts/arial.ttf:text=\'Hello World\':fontcolor=white@0.6:fontsize=70:x=0:y=40"',
  
               '-y',
  
               'c:\\path\\to\\my\\outputfile.mp4' ];
  
  
  
  // Above creates the command line equivalent of:
  
  // ffmpeg -i c:\path\to\my\inputfile.mp4 -vf drawtext="fontfile=/Windows/Fonts/arial.ttf:text='Hello fluent text':fontcolor=white@0.7:fontsize=70:x=0:y=40" -y c:\path\to\my\outputfile.mp4
  
  // this works when run from the command line
  
  
  
  var execCmd = cmd+' '+args.join(' ');
  
  
  
  child_process.exec(execCmd, function (error, stdout, stderr) {
  
          /* ffmpeg runs fine, adding the text to the video */
  
  
  
          var spawn = child_process.spawn(cmd,args);
  
  
  
          spawn.on('close', function (code) {
  
              /* ffmpeg fails, with standard error (obtained via spawn.stderr) reading:
  
                 Could not load font ""fontfile=/Windows/Fonts/arial.ttf": impossible to find a matching font
  
                 Error initializing filter 'drawtext' with args '"fontfile=/Windows/Fonts/arial.ttf:text=Hello fluent text:fontcolor=white@0.6:fontsize=70:x=0:y=40"'
  
              */
  
          });
  
      });

  Based on the error message :

  Could not load font ""fontfile=/Windows/Fonts/arial.ttf" : impossible
  to find a matching font

  And comparing it to giving ffmpeg a bogus font on the command line :

  Could not load font "/Windows/Fonts/bogus.ttf" : impossible to find a
  matching font

  It seems the problem is that when executed from spawn the drawtext argument is incorrectly parsed and "fontfile= is incorrectly making its way into the font's path. This does not happen when the same argument is executed with exec or from the command line. Is there any additional escaping that needs to be done when executing using spawn ?

• Installing GPAC's player - Errors

  25 janvier 2016, par VirMarGu

  I am working with Ubuntu 14.04 LTS 64 bits.
  I am trying to compile and install GPAC’s player (Osmo) in its latest version.

  I had an installed version, but I have tried to compile one new and finally, the previous one doesn’t already work fine.

  I have made the following steps :

  1. sudo apt-get install git
  
  
  
  2. git clone https://github.com/gpac/gpac.git
  
  
  
  3. sudo apt-get install subversion make pkg-config g++ zlib1g-dev libfreetype6-dev libjpeg62-dev libpng12-dev libopenjpeg-dev
  
  libmad0-dev libfaad-dev libogg-dev libvorbis-dev libtheora-dev

  libssl-dev libjack-dev libasound2-dev libpulse-dev libsdl1.2-dev
  
  dvb-apps libavcodec-extra libavdevice-dev libmozjs185-dev
  
  
  
  4. cd gpac

  I don’t know if the error is due to some incompatibility with the libraries or if I must uninstall the previous GPAC (I don’t know how to make it because there is no uninstall script).

  I will appreciate any help.
  Thank you !
