When executing streamutil the following may happen: *streamutil: ../src/pjmedia/codec.c:53: pjmedia_codec_param_clone: Assertion `pool && src' failed.* *Aborted (core dumped)* An uninitialized (optional) data structure (pjmedia_codec_param) causes this issue in stream.c/pjmedia_codec_param_clone. This is solved by perfomring a NULL pointer check as below (diff.txt) 2005c2005,2008 < stream->si.param = pjmedia_codec_param_clone(pool, info->param); --- > > if (info->param) > stream->si.param = pjmedia_codec_param_clone(pool, info->param); > -------------- next part -------------- An HTML attachment was scrubbed...
