@section sec1 raDIYo

Eine Mediaplayer-Software für den RaspberryPi, zugleich ein
Hardware-Updgrade eines Nora 'Rienzi' Radios, Bj. ca. 1935


@section sec3 Ideen & TODO:

@subsection sec3_1 TODO 1.0.xx RC

@remarks

Für 1.0x

    - lib vlc player nehmen!
        - videos einbauen, fürs geschmäckle
        - artist anzeigen
    - progressbar anzeigen
    - volume % einblenden
    - Qt 6.x upgrade
    - Gestensteuerung via Ultraschall Sensor
    - Dazu Arduino Bindings
    - Config per App
    - Röhrenoszi als Pegel Anzeige ??
    - mp3 taglib einsetzen
    - peak level halten im SpectroViewer
    - Player verbessern: Loop / Shuffle
    - Player verbessern: Lieblinslautstärke pro song speichern
    - Player verbessern: Liste weiterspielen

    @bug

    - Bluetooth-Einbindung läuft nur über Systemeinstellungen
