Hi! Following up this pending discussion: http://lists.live555.com/pipermail/live-devel/2016-March/019977.html

I have resume the previous analysis but I'm still trying to workaroud the Valgring overhead when running the full system. In between runs I've caught a valgrind alert when closing VLC players, after repeatedly connecting a pair of VLC clients to different ondemand stream. It doesn't crash but seems to be the same conditions when the segmentation fault is observed after some days. Based on this observation I've modified a test program in live555 and the problem seems to be observable when multiple ondemand subssession and one multicast are registered. DeviceSource -> StreamReplicator + -> multicast subsession: H264VideoStreamDiscreteFramer -> MPEG2TransportStreamFromESSource -> SimpleRTPSink + -> ondemand subsession 1: H264VideoStreamDiscreteFramer -> MPEG2TransportStreamFromESSource -> SimpleRTPSink + -> ondemand subsession 2: H264VideoStreamDiscreteFramer -> MPEG2TransportStreamFromESSource -> SimpleRTPSink I've only tested this with an H.264 ES live source encoder, I think it could be replicated with a lengthy file source. See valgrind output and RTSPServer debug output in the file attached to this message. Any suggestion to direct this analysis would be much appreciated.
