; This is an example configuration file that illustrates
; the structure of the configuration.
; It doesn't show all possible options. A more detailed example
; is available in doc/advanced.mux
;
; It contains two services, one DAB and one DAB+, and also shows
; both the file input useful for offline processing, and the
; ZeroMQ input useful in a 24/7 scenario.
; More information about the usage of the tools is available
; in the guide, which can be found on the
; www.opendigitalradio.org website.
;
; As you can see, comments are defined by semicolons.
;
; It consists of six mandatory sections, whose relative order in this
; file are of no importance.
; The general section defines global multiplex parameters.
general {
; the DAB Transmission mode (values 1-4 accepted)
dabmode 1
; the number of ETI frames to generate (set to 0 to get an unlimited number)
nbframes 10
; boolean fields can accept either false or true as values:
; Set to true to enable logging to syslog
syslog false
; Enable timestamp definition necessary for SFN
; This also enables time encoding using the MNSC.
tist false
; The management server is a simple TCP server that can present
; statistics data (buffers, overruns, underruns, etc)
; which can then be graphed a tool like Munin
; The doc/stats_dabmux_multi.py tool is a suitable
; plugin for that.
; If the port is zero, or the line commented, the server
; is not started.
managementport 12720
}
remotecontrol {
; enable the telnet remote control server on the given port
; This server allows you to read and define parameters that
; some features export. It is only accessible from localhost.
; Set the port to 0 to disable the server
telnetport 12721
; The remote control is also accessible through a ZMQ REQ/REP socket,
; and is useful for machine-triggered interactions. It supports the
; same commands as the telnet RC.
; The example code in doc/zmq_remote.py illustrates how to use this rc.
; To disable the zeromq endpoint, remove the zmqendpoint line.
; By specifying "lo" in the URL, we make the server only accessible
; from localhost. You can write tcp://*:12722 to make it accessible
; on all interfaces.
zmqendpoint tcp://lo:12722
; the remote control server makes use of the unique identifiers
; for the subchannels, services and components. Make sure you
; chose them so that you can identify them.
}
; Some ensemble parameters
ensemble {
id 0x4fff ; you can also use decimal if you want
ecc 0xec ; Extended Country Code
local-time-offset auto ; autmatically calculate from system local time
; or
;local-time-offset 1 ; in hours, supports half-hour offsets
; all labels are maximum 16 characters in length
label "OpenDigitalRadio"
; The short label is built from the label by erasing letters, and cannot
; be longer than 8 characters. If omitted, it will be truncated from the
; label
shortlabel "ODR"
}
; Definition of DAB services
services {
; Each service has it's own unique identifier, that is
; used throughout the configuration file and for the RC.
srv-fu {
id 0x8daa
label "Funk"
; you can define a shortlabel too.
}
srv-ri {
id 0x8dab
label "Rick"
}
}
subchannels {
sub-fu {
; This is our DAB programme, using a file input
type audio
inputfile "funk.mp2"
bitrate 128
id 10
protection 3
}
sub-ri {
; This is our DAB+ programme, using a ZeroMQ
type dabplus
; Accepts connections to port 9000 from any interface.
; Use FDK-AAC-DABplus as encoder
inputfile "tcp://*:9000"
bitrate 96
id 1
protection 3
; ZMQ specific options, mandatory:
; Maximum size of input buffer, in AAC frames (24ms)
; when this buffer size is reached, some frames will be
; discarded to get the size again below this value.
; As the present implementation discards entire AAC superframes,
; (5 frames = 120ms) the effect will clearly be audible.
zmq-buffer 40
; At startup or after an underrun, the buffer is filled to this
; amount of AAC frames before streaming starts.
zmq-prebuffering 20
; In an ideal scenario, where the input rate exactly corresponds
; to the rate at which the frames are consumed by dabmux, you
; see the buffer level staying around the zmq-prebuffering value.
; Network latency jitter can make it temporarily go lower or higher.
; Encoder clock drift will make the buffer either slowly fill or
; empty, which will create intermittent glitches.
}
}
; In our simple example, each component links one service to one subchannel
components {
; the component unique identifiers are used for the RC.
comp-fu {
; According to specification, you should not define component labels if
; the service is only used in one component. The service label is sufficient
; in that case.

; A list of outputs
outputs {
; The unique-id can be used by the remote control or the statistics server
; to identify the output
; Output RAW ETI NI to standard output
stdout "fifo:///dev/stdout?type=raw"
; ZeroMQ output example
; This output does not back-pressure the multiplexer.
; Listen on all interfaces, on port 9100
;zmq "zmq+tcp://*:9100"
; Output ETI-over-TCP. This is like piping a RAW ETI NI data stream
; into a TCP socket, except that the output can handle simultaneous
; connections.
; 0.0.0.0 means "listen on all interfaces"
; This output does not back-pressure the multiplexer.
;tcp "tcp://0.0.0.0:9200"
; Throttle output to real-time (one ETI frame every 24ms)
;throttle "simul://"
; Important! For real-time operation, you need to have exactly one
; output that applies back-pressure to ODR-DabMux, otherwise it will run
; at the highest possible rate on your system!
;
; For an output to a pipe, the data consumer at the other end of the pipe
; will dictate the multiplexing rate to ODR-DabMux.
;
; If you use the zmq+tcp:// or the tcp:// output,
; you must also enable a simul:// output!
