The HTTP Streamer can be enabled via the _streamer_enabled_ daemon parameter.
When the Streamer is active the daemon starts capturing the configured _Sinks_ up to the maximum number of channels configured by the _streamer_channels_ parameters.
The captured PCM samples are split into _streamer_files_num_ files of _streamer_file_duration_ duration (in seconds) for each sink, compressed using AAC LC codec and served via HTTP.
The HTTP streamer requires the libfaac-dev package to compile.
Please note that since the HTTP Streamer uses the RAVENNA ALSA device for capturing it's not possible to use such device for other audio captures.
This fixes a problem on old Ubuntu distro causing the Node ID to be the same for multiple hosts.
Additional minor changes:
- removed compilation warnings
- some fixes to code indentation
- 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.
Added to the WebUI the possibility to directly select a remote source SDP file for a Sink.
