http://trac.pjsip.org/repos/wiki/Video_Users_Guide#WindowsDesktopVisualStudio Frogerisk, I do follow that guide. I'm using the latest ffmpeg git repository (FFMPEG_VERSION "0.9.1.git"), that bring a problem not related to this compilation problem. Errors for using latest version of ffmpeg: * avcodec_init is deprecated and undefined so I have to remove it from ffmpeg_codecs.c * if I compile the project defining "#define PJMEDIA_VIDEO_DEV_HAS_DSHOW???? 0" the project does not present the compilation problem i am having, but the ffmpeg video codecs are not present when I use pjsua application. This two problems are solved using an older version of ffmpeg. These are my paths for include: F:\Program Files\Microsoft DirectX 9.0 SDK (Summer 2004)\Include? DIRECT X F:\SDL-1.3.0-6248\include SDL 1.3 These are my paths for link: F:\Program Files\Microsoft DirectX 9.0 SDK (Summer 2004)\Lib DIRECT X F:\SDL-1.3.0-6248\VisualC\SDL\DebugSDL 1.3 F:\Program Files\Microsoft SDKs\Windows\v6.1\Samples\Multimedia\DirectShow\BaseClasses\Release DirectShow I tried building BaseClases of direct show using both Multi-threaded DLL and Multi-threaded Debug DLL but both bring a lot of compiling errors.
