Aborted The complete log file is PFA(error.log). I put a debug statements in the source code I realized that it is invoking pj_pool_create(it is in pjsource/pjmedia/src/pjmedia-videodev/sdl_dev.c). And throwing error like that. why the error was happened, I am unable to debug this issue please help me to get out of this error. Thanks in advance.
