Building Libraries (Audio / Video Codecs)

The dvdplayer depends on other libraries to function. These libraries are included in SVN by default as dll's under the "XBMC/system/players/dvdplayer" subfolder. The full source code of these libraries can be found under the "/docs/sources/dvdplayer/" subfolder in the SVN. To build these dll's yourself you need to have the following installed, (the .dll's must be then be placed under the "[XBMCFOLDER]/system/players/dvdplayer" subfolder).

• MinGW and MSYS
  • see http://ml20rc.msnfanatic.com/ffmpeg/1.html for installation for ffmpeg
  • use binutils version 2.16.91 (20060119) 1
• unrar
