Hello everyone, I am very new to PJSIP and FFMPEG both. but need to develop one application using both. I am trying to build PJSIP by enabling FFMPEG flag , but getting lots of error. Could any one help me building the same? so I am following these steps: 1. got source code of PJSIP from their website 2. created config_site.h with android flag and added video and ffmpeg flag to true. 3. Added ffmpeg include path in make file of PJSIP. 4. ran ./configure-android , make dep, make I am getting errors with undefined references to ffmpeg symbols. The other problem is I am not able to get proper steps to build ffmpeg for Android. I will appreciate any help on this. Thanks Irfan
