Hi,
That's rather strange, since the max_len supposed to be bigger (much bigger)
than that. Moreover, streamutil.c also uses pjmedia stream (including rtcp)
so it should face the same problem. For now, please try to clean and
rebuild the whole pjsua project first, if the problem persists, please help
us to reproduce (e.g: describe pjsua command line params, etc), I have never
got this assertion before and AFAIK, RTCP SDES should have nothing to do
with codec.

nanang
