GUI4ODR

Creating a graphical user interface (GUI) written by JavaFX that controls the configuration of the DAB ODR-mmbTools.

1. New/Open Configuration:

At the beginning created a new configuration. Alternative open a configuration-file.

Note: Loading externally created configuration doesn't work to 100% Reason: The complexity of configuration settings! Solution: Save the complete configuration by GUI and open it.

2. Configure:

• The Configuration in first three Tabs from GUI (Multiplex, Components, Subchannels) based on ODR-DabMux.
• The Configuration in "Subchannels"-Tab based on ODR-AudioEnc and ODR-PadEnc. In the future a Data-Encoder could be added.
• The Configuration in "Outputs"-Tab based on ODR-DabMux and ODR-DabMod. Between the ODR-Tools is always used ZeroMQ, with generated ports.

2.1 Specially:

Subchannel supported Input from Audio and Data.

Audio-Inputs:

• Webstream (over libvlc)
• ALSA
• JACK

Outputs (combine DabMux and DabMod):

• Device (FarSync Card, Ettus USRP)
• File (ETI-NI File, I/Q-Samples File)
• Network (EDI, ETI: UDP, TCP; ZeroMQ: ETI, I/Q-Samples;)

3. Save Configuration:

If the configuration is to be stored, the user selects a folder or create a new one.

Files (don't rename it) inside project folder:

• dab.mux: Multiplex Configuration File
• xxxx.mod: Modulator Configuration File for DabMod (filename equals output-name in dab.mux)
• dab.sh: Bash-File to start all processes with screen (GUI didn't execute this skript, only the processes without screen)

4. Execution:

If the complete configuration is without errors, it can be executed.

5. Monitoring

The GUI managed all Processes from ODR-Tools. If a process crashes or terminates, the user would be informed over a Alert-Window and additionally with E-Mail.

6. Addition

• Remote Control: TeamViewer, VNC, ...
• Check ETI-Stream: dablin_gtk (https://github.com/Opendigitalradio/dablin) -> need to create a ETI-File-Output (FIFO) for dablin input.
• Audio VU-meter: e.g. pavumeter (sudo apt-get install pavumeter)
• E-Mail-Log: need configure 'postfix' with exist Mail-Account (https://help.ubuntu.com/community/Postfix) and enter receiver Mail-Address in the GUI

Required:

• ODR-DabMux >= v1.1.0
• ODR-DabMod >= v0.5.4
• ODR-AudioEnc >= v2.0.0
• ODR-PadEnc >= v2.0.0
• JAVA JRE Version >= 8

Pre-Installation

• Check the required Softwares
• Under UNIX => Install Open-JavaFX ("sudo apt-get install openjfx")

Installation:

• Set the executable Bit under Settings and run with double click
• open Console and start GUI with command "java -jar /path/of/the/jar/file.jar"

Status: v0.6 -- fix bugs

• Open a new Configuration ==> work
• Open a Configuration ==> work
• Configure ==> work
• Save ==> work
• Execution ==> work
• Monitoring ==> work
