Hi pjsip group, this is my problem When I run streamutil it is showing this error: 11:20:24.458 os_core_unix.c !pjlib 2.1-svn for POSIX initialized 11:20:24.482 pa_dev.c PortAudio sound library initialized, status=0 11:20:24.482 pa_dev.c PortAudio host api count=1 11:20:24.482 pa_dev.c Sound device count=3 11:20:24.482 pjlib select() I/O Queue created (0x7ffde2004028) Assertion failed: (pool && src), function pjmedia_codec_param_clone, file ../src/pjmedia/codec.c, line 53. An assertion in function pjmedia_codec_param_clone in file codec.c is failing the assertion is PJ_ASSERT_RETURN(src, NULL); where src is defined as: const pjmedia_codec_param *src and is passed in the function arguments. So i think it means that the passed value of src is NULL but I am not getting that from where this value is being passed to this function. In streamutil.c, the problem occurs when the pjmedia_create_stream function is called in create_stream function. This problem is in 2.1 version. In 2.16 version no occur Thanks Santi -------------- next part -------------- An HTML attachment was scrubbed...
