• 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
  
  Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies

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

• New builds for PHP 5.4 and PHP 5.3

  29 novembre 2012, par Mikko Koppanen — Imagick

  It’s been a while since I last updated this blog (September 2009 to be exact). Time flies ! Anyway, here comes the actual content : updated imagick binaries for PHP 5.3 and PHP 5.4. The download package also includes ImageMagick 6.8.0 binaries compiled with VC9 (Visual Studio 2008). I noticed that the official ImageMagick builds are now Visual Studio 2010 and that wouldn’t work well with PHP compiled with 2008.

  I am not sure if I am violating any license in distributing ImageMagick binaries but if I do, please let me know and I will remove them. The binaries are just stock ImageMagick 6.8.0, which you can download from http://imagemagick.org/.

  In order to get things running you should add the ImageMagick DLL directory into PATH, add the imagick extension to php.ini and things should be running. At least hopefully.

  The download link for the binaries is here : imagick-php54-php53.tgz.

• Working way to make video from images in C#

  26 octobre 2013, par Jim Mischel

  Does anybody have a known reliable way to create a video from a series of image files ? Before you mod me down for not searching for the answer before posting the question, and before you fire off a simple message like "use FFMPEG," read the rest of this message.

  I'm trying to create a video, it doesn't matter too much what format as long as it's widely supported, from a series of images (.jpg, .bmp, etc.). My platform is Windows Server 2008, 64-bit. If I can make the video from within my C# program, that's great, but I'm not averse to writing a series of image files to a directory and then firing off an external program to make a video from those images.

  The only constraints are : it must work on my Windows Server 2008 system, and be scriptable. That is, no GUI programs that require operator intervention.

  I found a number of similar questions on StackOverflow, and have tried several of the solutions, all with varying degrees of frustration and none with anything like success.

  FFMPEG looks like a great program. Maybe it is, on Linux. The two Windows builds I downloaded are broken. Given this command line :

    ffmpeg -r 1 -f image2 -i jpeg\*.jpg video.avi

  One of the builds reads the images and then crashes due to data execution prevention. The other reads the first file and then spits out an error message that says "cannot find suitable codec for file jpeg/image2.jpg". Helpful, that. In any case, FFMPEG looks like a non-starter under Windows.

  One answer to a previous posting recommended Splicer . It looks like pretty good code. I compiled the samples and tried to run, but got some cryptic error message about a file not found. It looks like a COM class isn't registered. I suppose I need to install something (DirectShow, maybe, although I thought that was already installed ?). Depending on what's required, I might have a difficult time justifying its installation on a server. ("What ? Why do you need that on a server ?")

  Another answer suggested the AviFile library from Code Project. That looks simple enough : a wrapper around the Windows AviFile subsystem. Except that the AVI files the package creates appear to have all of the frames, but only the first frame shows when I play the AVI in Windows Media Player. Well, that and if you try to create a compressed video, the program throws an exception.

  So, I'm left wondering if there is a good, reliable way to do what I want : on a Windows system, create an AVI or other common video file format from a series of images, either through a .NET API or using an external program. Any help ?
