• ffmpeg latest visual studio builds or linking with (.a) libs

  23 juin 2013, par user1657348

  there is a problem.
  I need to link ffmpeg(particularly libavcodec) statically into visual studio 2008 project.

  I found some visual studio solutions in internet but they are very old (around 0.6 version) and i need latest version, so this way is not an option for me.

  Next, I made static build (with —enable-satic —disable-shared flags) using MinGW/msys and obtained (*.a) libraries in output.
  In Visual Studio I go to the linker properities and add to Additional Dependencies(Linker->Input) libvacodec.a and libgcc.a.
  Then i wrote simple application :

  #include 
  
  #include 
  
  extern "C"
  
  {
  
     #ifdef  __STDC_CONSTANT_MACROS
  
        #define __STDC_CONSTANT_MACROS
  
     #endif
  
        #include "libavcodec/avcodec.h"    
  
   }
  
  
  
  
  
  
  
  #include "libavformat/avformat.h"
  
  
  
        int main()
  
     {
  
      av_register_all();
  
      return 0;
  
     }

  Compilation of this code was succeeded but linking failed. There is an error was obtained :

  error  LNK2019: unresolved external symbol "void __cdecl av_register(void)" (?av_register_all@@YAXXZ) referenced in function _main.

  So, there are two questions :

  1. How to link Visual Studio application with libavcodec.a ?

  2. If it possible, where can i get visual studio solution which includes ffmpeg latest version ?

  Thanks in advance !!

• 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.
