- mDNS advertisement for all local Sources is implemented by mdns_server.[cpp,hpp] and based on Linux Avahi. - RTSP server implementation supports DESCRIBE method to return SDP of local Sources and supports persistent connection but doesn't provide service updates via UPDATE method. - Modified RTSP client to browse for _ravenna_session subtype of _rtsp._tcp services only. - Modified SAP and mDNS discovery to avoid returning local Sources advertised by the daemon. - Added "rtsp_port" and "node_id" config parameters. - rtsp_port is a read/write parameter that contains the port of the RTSP server. - node_id is a read only parameter that contains the unique daemon identifier used in mDNS and SAP sources announcements. - Modified session manager to check that every Source and Sink created by the user has a unique name. - Modified WebUI to visualize node_id and to visualize and edit rtsp_port parameters in Config tab. - Extended regression test to verify proper behaviour of mDNS/RTSP sources advertisement and discovery. - Modified REST API to browse remote sources to allow browsing of SAP, mDNS and all sources via HTTP GET /api/browse/sources/[all|mdns|sap]. - Amended daemon documentation.
