    dabmode 1

    ; 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.

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
    ;telnetport 0

    ; 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.

        ; 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.

    ; connections.

    ; 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!
