Hello all, Hello Teluu, at the moment, it is not possible to compile PJSIP trunk from SVN without video support. The attached patch fixes this issue. I would be grateful if you could review and integrate this patch. I know I also promised a rewritten patch for C++ 17 support for PJSUA2, but unfortunately this task lost priority on my side because I had to switch back to C++14. I hope to still submit this patch at a later timer. My apologies for that. Best regards and have a nice day,    Christian
