Earlier I was getting Assertion failed because pjmedia_codec_param variable of info structure was not initialized. So I initialized it using malloc but now I am getting FLOATING POINT EXCEPTION because the values of pjmedia_codec_param structure's variables are still NULL and in pjmedia_create_stream of stream.c, these variables are used in division because of which I am getting the exception. Now I have to set those values, please somebody suggest what should I set those variables to. Thanks in advance. -- Udit Agarwal B.Tech.
