Build live555 libraries with -DUSE_SYSTEM_RANDOM=1 by default. This fixes a bug reported by Jason Gerecke (jgerecke at uoregon dot edu). The rationale from Jason:

In groupsock/inet.c: http://www.live555.com/liveMedia/doxygen/html/inet_8c-source.html a custom random generator is provided for systems which do not provide their own rand() or srand() functions. Other people have reported issues with this function segfaulting (never in conjuction with VLC however), possibly because of multithreading issues, and the fix issued by the Live555 developers was to provide an "#ifdef USE_SYSTEM_RANDOM" for builds on supporing systems (http://lists.live555.com/pipermail/live-devel/2003-November/000013.html).
