Building decklink for windows using cerbero

[Felipe Mogollon]

Hi,

thanks for your aclarations, I have managed to build it using meson as you
said: I explain how I did it just for info:


Prerequisites:

1. Install MinGW
2. Install Perl3
4. Install glib for windows


   1. go to http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/
   2. download the file pkg-config_0.26-1_win32.zip
   <http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/pkg-config_0.26-1_win32.zip>
   3. extract the file bin/pkg-config.exe to C:\MinGW\bin
   4. download the file gettext-runtime_0.18.1.1-2_win32.zip
   <http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/gettext-runtime_0.18.1.1-2_win32.zip>
   5. extract the file bin/intl.dll to C:\MinGW\bin
   6. go to http://ftp.gnome.org/pub/gnome/binaries/win32/glib/2.28
   7. download the file glib_2.28.8-1_win32.zip
   <http://ftp.acc.umu.se/pub/gnome/binaries/win32/glib/2.28/glib_2.28.8-1_win32.zip>
   8. extract the file bin/libglib-2.0-0.dll to C:\MinGW\bin

5.Edit meson.build files to get only decklink build

   * Edit gst-plugins-bad mson.build and remove all subdir('xxx') except
subdir('sys')

   * Edit sys/meson.build and keep only subdir('decklink')


Building :

1. Execute Developer Command Line from Visual Studio 2015
2. Add C:\MinGW\bin and C:\MinGW\msys\1.0\bin to Developer Command Line Path
   set PATH=%PATH%; C:\MinGW\bin;C:\MinGW\msys\1.0\bin
3. Execute meson in your gst-plugins-bad folder:
    python3 C:\your_path_to_meson_0_41\meson.py build --backend vs2015
4. Open the solution created in your build folder in Visual Studio 2015
5 Set Target Machine to win64
   Your Solution->Your project->right
button->properties->Linker->advanced->Target
Machine->MachineX64
6 Build
