I have finally solved the problem to build pjsip 2.2.1 with video support, by issuing: make distclean before issuing ./configure make dep make make install Now pjsip 2.2.1 with video support (set by #define PJMEDIA_HAS_VIDEO in pjlib/include/pj/config_site.h) compiles correctly on my Rasperry. I hope that this could be an useful suggestion to everyone that could find problems in pjsip compilation ;) Best regards Silvio
