- changed cpp-httplib git submodule path to https://github.com/bondagit/cpp-httplib.git
- removed compilation warning related to the usage of Boost bind global placeholders
- updated daemon version to 2.0.2
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.
The daemon can apply a configuration change to the following parameters without a restart:
sap_interval, syslog_proto, syslog_server, log_severity, sample_rate
The daemon can apply a configuration change to the following parameters without a light restart:
http_port, rtsp_port, http_base_dir, rtp_mcast_base, sap_mcast_addr, rtp_port, rtp_port, status_file, interface_name, mdns_enabled
A light restart means that the configuration can be applied without interrupting the playback/capture applications
A change to one of following paramters causes a full daemon restart:
interface_name, tic_frame_size_at_1fs, max_tic_frame_size
On PTP status change the daemon can run in background an external shell script whose path name is specified by the new ptp_status_script Config parameter.
If this parameter is empty, no script is invoked. The PTP clock status is passed as first parameter to the script and it can be unlocked, locking or locked.
A sample script is provided in daemon/scripts/ptp_status.sh
- fixed handling of Max samples per packet Source parameter in the WebUI and added computation of the real frame duration
- fixed max number of channels configurable for a Sink in the WebUI
- fixed tic_frame_size_at_1fs daemon parameter documentation
- changed daemon default sample_rate parameter to 48000 Hz
- aligned state handling with avahi-browse tool: browser is started in client callback
- browsing is limited to IPv4 services discovered on the specific daemon network interface only
Additional minor changes.
Added to the WebUI the possibility to directly select a remote source SDP file for a Sink.
New files:
daemon/mdns_client.hpp,cpp -> mDNS client implementation using Avahi client library
daemon/rtsp_client.hpp,cpp -> RTSP client implementation used to transfer SDP file
daemon/utils.cpp -> used for common utility functions
.clang-format -> added clang-format configuration file
Modified files:
daemon/CMakeList.txt -> added support for Avahi and option WITH_AVAHI=[yes/no] to compile the daemon with or without Avahi mDNS support
daemon/config.hpp,cpp -> added configuration option mdns_enabled to enable or disable mDNS discovery at runtime
daemon/json.cpp -> extended JSON config with mdns_enabled option
daemon/browser.hpp,cpp -> added support for mDNS client to the browser
daemon/session_manager.cpp -> added support for RTSP protocol to Source URL field and fixed issue with SDP file parsing
webui/RemoteSources.js -> added visualization of mDNS remote sources
webui/SinkEdit.js -> added the possibility to directly select a remote source SDP file for a Sink
webui/SourceInfo.js -> added visualization of protocol source (SAP, mDNS or local) for a source
ubuntu-packages.sh -> added libavahi-client-dev to the list of required packages
build.sh -> added WITH_AVAHI=yes option when invoking CMake
README.md -> added notes about mDNS support via Avahi
daemon/README.md -> added notes about mDNS support via Avahi, support for RTSP protocol in source and new mdns_enabled config param
Additional minor changes to remaining files.
- added "sap_mcast_addr" parameter to daemon conguration and WebUI to configure the SAP multicast address used for sending and receiving source announcements
- added REST API to retrieve the remote sources collected by the daemon (GET /api/browse/sources)
- added Browser tab to the WebUI to visualize info on the available remote sources
- added Info function to sources listed in the Sources tab to visualize the associated SDP file
- extended daemon regression tests to test the SAP Browser
