This is an old revision of the document!

All notable changes to OnAirScreen. Source: OnAirScreen CHANGELOG.md (wrapped as Markdown). Narrative release notes: 1.0.0 · 0.9.8.

All notable changes to this project will be documented in this file.

Right-click menu shows the current OnAirScreen version as info
Raspberry Pi SD-card image allows passwordless host reboot and shutdown from OnAirScreen

Application log starts with a Starting OnAirScreen line (version and distribution)

Linux PTP logs whether the 319/320 bind helper is missing or failed
Linux PTP bind helper receives the comm socket on stdin

Web UI and API command FULLSCREEN:ON/OFF/TOGGLE to switch the main window
Reboot and Shutdown buttons in Settings → About and the Web UI (with confirmation); HTTP CMD:REBOOT / CMD:SHUTDOWN require the Web Settings PIN when one is set
GPIO (Raspberry Pi and Livewire) can map one input to several preset actions plus semicolon-separated custom commands

add SNMP enterprise OID IANA PEN 66873 (.1.3.6.1.4.1.66873); remove placeholder
SNMP MIB is published on the wiki (onairscreen:mib-en)

Closing the main window while Settings is still open now exits the app
Linux/Raspberry Pi PTP binds UDP 319/320 via a small helper so the app can run as a desktop user

SNMPv2c/v3 agent (GET/SET/WALK on port 1161, optional traps) for LEDs, AIR timers, texts, silence, and loudness; MIB in mibs/ASTRASTUDIO-ONAIRSCREEN-MIB.txt; Settings Network tab shows SNMP beside UDP/MQTT/OSC
Axia Livewire GPIO LWRP: follow GPI/GPO on a device over TCP 93 (read-only), alongside multicast

Weather widget backgrounds use a new photographic set for OpenWeatherMap icons 01d–50n

SNMP GET for NOW/NEXT/WARN and other status objects reads the live screen instead of an empty cache
SNMP agent no longer logs an asyncio error when OnAirScreen quits
Timer dialog accepts 2:10 as well as 2,10 and 2.10
Timer dialog selects the existing value when opened with Enter
Weather widget labels stay readable on bright photo backgrounds (soft shadow + overlay)
Web settings: GPIO Custom Command is disabled unless Action is Custom
Web settings GPIO row fields are disabled unless that GPI Enable is on
Desktop GPIO row fields are disabled unless that GPI On checkbox is on

Axia Livewire GPIO (multicast): follow a source channel’s GPO/GPI pins (e.g. mic ON lamp) in parallel with Raspberry Pi GPIO
Main-window hotkey overlay (H, or right-click / long-click → Hotkeys): lists shortcuts; close with H, Esc, or a click outside. Other hotkeys are blocked while it is open

PTP: retry UDP 319/320 bind when the ports are in use or permission is denied; log the cause; lock LED and WARN show PTP ERROR until bind succeeds
German manual links to the English GPG wiki page (gpg-en); the German GPG how-to is removed

First stable 1.0.0. Changes since 0.9.8 are listed in the 1.0.0beta sections below.

Require python-osc >=1.10.2

LED and AIR timer on and off color changes take effect immediately after Apply

Analog clock faces Analog Numbers (1–12 on the classic analog face), Analog Studio (white face with 1–12), Analog Railway (station clock with a red ring second hand), Analog 24h ticking, and Analog 24h smooth (cream face with 1–12 and 13–24)
Clock face setting Clock/face and CONF:Clock:face= for digital and analog styles
README and manuals show screenshots of all clock faces

Clock mode in Settings and the Web UI is a dropdown instead of Digital/Analog radio buttons
Context menu Start/Stop/Reset I+LRA are enabled only when they apply to the current session
CONF:Clock:digital=False selects the classic analog face

I/LRA no longer burns a CPU core on long sessions: history stays in a NumPy buffer, blocks below −70 LUFS are not stored, and gated I is refreshed about once per second

Settings option to always start in fullscreen mode, even if the last session was windowed (General/always_start_fullscreen, default off)

GitHub README presents shop builds as the supported way to run OnAirScreen; the repository is documented as source-available for audit and contributors, not as an installer
Automatic update checks also run every 24 hours while OnAirScreen is running; the new-version dialog appears only at startup
Audio meter width can be set up to 201 px (L/R bars were previously capped around 117 px)
Installation chapter in the manuals covers Windows MSI, macOS Gatekeeper, Linux packages, and flashing the Raspberry Pi SD image
Manuals use an annotated main-screen screenshot

Long-press on the main screen no longer uses deprecated Qt mouse-position APIs

Long-click / long-press on the main screen opens the same context menu as right-click

Raspberry Pi GPIO import of system gpiozero no longer fails for missing freeze stdlib modules (colorsys, fractions)

Raspberry Pi GPIO works in the packaged app by loading system python3-gpiozero / python3-lgpio (the freeze does not bundle them)

Raspberry Pi GPIO inputs map mixer GPI contacts to LEDs and AIR timers (Settings → GPIO), with wiring diagrams and pinout links in the manuals

GPIO wiring diagrams in the manuals show a PC817 module with silkscreen terminals IN1–IN8 / GND and OUT1–OUT8 / GND

Left-click on status LEDs and AIR timers toggles them (same as the hotkeys)
Right-click Quit OnAirScreen on the main screen
On-screen WARN QUITTING ONAIRSCREEN while the app is shutting down
Web UI Add to Home Screen on iPhone/Android uses the OnAirScreen icon

Web UI uses a flat studio look: CI color blue, square inputs, and settings tabs on the left like the desktop dialog
Web UI theme, settings, and version controls scroll with the page instead of staying pinned to the corners

Web UI AIR timer and loudness buttons no longer overflow the viewport on phones
Web UI home-screen icon is an opaque 180×180 PNG at the site root so iOS picks it up
Ctrl+C / SIGINT shows the same QUITTING ONAIRSCREEN WARN as Q and the context menu
Opening Settings / Apply no longer segfaults on Raspberry Pi: the Python mouse event filter is gone; main-screen children let double-click and right-click through to the window
Audio meter heading "LUFS" in the L/R + LUFS layout is no longer clipped on the left and right

Settings window opens at 700×800 and can be resized freely (height is no longer capped at 800px)

Settings tabs (except General) scroll vertically in the UI; content stays within the window width instead of shifting sideways
Audio meters use much less CPU on Raspberry Pi and other software-rendered displays: bars paint from cached pixmaps, and true-peak / BBC PPM / LUFS DSP runs only when the current meter setup needs it
Opening Settings no longer segfaults: the main-screen mouse filter watches the application instead of installing on every new child widget
Replaced deprecated QColor.setNamedColor() with QColor.fromString()
Web UI: Instance/Version/Connection block stays top-right; settings gear sits to its left

Right-click Start I+LRA and Stop I+LRA on the main screen (when meters are enabled)
Web UI settings overlay (gear, top right): edit all OnAirScreen settings, optional PIN (Network/websettingspin), Apply, and preset load/save
Web UI Audio Meters: Livewire Source and AES67 Stream dropdowns with live discovery and Paste SDP, matching the desktop Settings dialog

Default TOTH timer label is TOTH instead of TOTH Timer

Windows: opening Settings → Fonts no longer access-violates on first open. The mouse event filter is installed after widgets exist, and the font database is warmed at startup
Main-screen hotkeys work again. The mouse event filter no longer consumes ShortcutOverride and key events, so QShortcut still reaches Qt

Persistent log folder with rotating onairscreen.log, crash reports for uncaught Python exceptions, and fault.log for native faults; About tab shows the path and can open the folder
After a crash, the next start shows a dialog (open log folder, auto-closes after 30 seconds with a progress bar)

Uncaught main-thread exceptions and Qt fatal messages write a crash report, then quit (no dialog at crash time). Thread and asyncio errors are logged without exiting.

Fresh installs without Audio/layout now use L/R + LUFS (both) instead of falling back to L/R only
Settings audio-device Refresh re-scans PortAudio so newly plugged or unplugged inputs appear immediately

OnAirScreen Source-Available License (OASL 1.0): source may be used, modified, and redistributed; compiled/binary redistribution requires written permission
Application file headers point to OASL; Settings License tab shows OASL plus third-party notices

TOTH Timer label text is configurable (Timers/TimerTOTHText, default TOTH Timer)
Bundled Noto Sans (Regular, Bold, Italic, Bold Italic) as an additional font family alongside Roboto
Web-UI Loudness I+LRA tile shows live I (LUFS) and LRA (LU); lufsI / lra in /api/status and WebSocket; MQTT sensors {base}/lufs/i and /lra; OSC /oas/lufs/i and /oas/lufs/lra

Weather widget text shadows work again under PySide6 (drop-shadow effects are parented so they are not garbage-collected)
AoIP source change without RTP now drops the meters to the floor instead of freezing on the previous level

Settings Network and Time Source tabs align labels and fields in a shared two-column form layout
License dialog and THIRD_PARTY_LICENSES.md now document PySide6/Qt (LGPLv3), the analog clock BSD example, and Roboto (SIL OFL) instead of PyQt GPL
Application BSD text removed from LICENSE and the Settings license tab pending the forthcoming source license
Default audio meter layout is L/R plus programme LUFS (both); default width is 115px and the maximum is 150px

Digital clock no longer aborts when a time sample has no SMPTE frame count
Startup no longer crashes when listing host addresses under PySide6

Qt binding switched from PyQt6 to PySide6
Settings window opens at 700×800 and is capped at 800px height so it fits smaller screens, audio meters tab uses two columns
Station and slogan color pickers in Settings no longer show a live preview
dBTP meter hides the orange ceiling peg when the Too Loud indicator is off

Meter layouts: L/R only, programme LUFS only, or both (Audio/layout: lr / lufs / both; BBC PPM stays L/R-only)
Programme LUFS bar (EBU R128): momentary M with a short-term S tick (I and LRA stay off until started)
Optional gated Integrated I + LRA (off until started): LUFSI:START / STOP / TOGGLE / RESET via UDP, HTTP, OSC, MQTT, Web-UI, and Companion
MQTT Home Assistant: Loudness I+LRA switch and reset button ({base}/lufs/integrated/set and /state); lufsIntegrated in /api/status and WebSocket
Right-click Reset I+LRA on the main screen (when meters are enabled); LUFSI:RESET restarts a running session or hides frozen I/LRA when stopped
Existing configs with Audio/unit=lufs (no layout key) migrate to layout lufs and L/R unit dbtp
AIR3 shows ▲ (count-up) or ▼ (count-down) under the timer icon
AIR3 shows TOTH Timer while top-of-hour countdown is active, then restores the configured label
Web-UI: AIR3 time input (m:ss, m,ss, or seconds) and count-up vs. countdown in the status tile
Web-UI: silence alarm and loudness I+LRA in live status; keys 1–4 toggle LEDs (ignored while typing)
Web-UI: persistent connection badge (Live / Polling / Offline)
countDown in /api/status for AIR timers (true while AIR3/AIR4 is counting down)
Bitfocus Companion HTTP module (astrastudio-OnAirScreen) as the recommended Stream Deck path; Generic OSC remains as an alternative
OSC remote control on UDP port 8000 (/oas/...): set commands, query-reply to the sender, optional status push for Companion Generic OSC
Settings Network tab (after General) for UDP, HTTP, multicast, MQTT, and OSC; General / Advanced tab titles no longer include “Settings”
Silence Detection on the current audio source (Local / Livewire / AES67): dBFS threshold, duration (default 10 s), recovery time, optional OAS WARN, optional HTTP GET on trigger
Silence alarm as API boolean (silence in /api/status and WebSocket) and MQTT {base}/silence/active (Home Assistant binary sensor)
Option to treat a missing device/stream as silence (on by default)
DNS-safe instance name (Settings General, default Studio-1, max 32 characters, LDH hostname label) so each OnAirScreen can be identified by location; shown in the Web-UI, /api/status (instance), MQTT {base}/instance/state, and as a Home Assistant sensor; HA device name becomes OnAirScreen (Studio-1)
CONF:General:instancename=TEXT to set the instance name remotely
Double-click on the main screen toggles fullscreen
Right-click context menu on the main screen: Toggle Fullscreen, Settings

Default meter width is 79 px (extra width still thickens the L/R bars)
CONF:Audio:unit=lufs now switches the layout to programme LUFS instead of using LUFS as an L/R unit
Default audio meter unit is dBTP; TooLoud is enabled by default

Clock no longer freezes after an NTP timeout: NTP results are delivered on the GUI thread, and a watchdog restarts a dead clock timer
Clock watchdog no longer aborts when a time sample is missing
Opening Settings no longer paints a running AIR timer (including TOTH) as inactive or resets its displayed time to 0:00
Web-UI restores the WebSocket after falling back to HTTP polling
Opening Settings again brings the existing window to the front instead of reloading it

Stereo audio meters on the left (on by default, Local Input): L/R bars with RMS fill and peak overlay
Display units: dBFS, dBTP (true peak), LUFS (momentary), BBC PPM (Type IIa, marks 1–7)
Peak hold marker (default 1.5 s, can be disabled) and display style Solid or Bargraph
LUFS reference peg via presets (EBU R128 −23, ATSC A/85 −24, AES −16/−18, Custom)
Adjustable meter width (extra width goes into thicker L/R bars)
Optional TOO LOUD action: on-screen warning (priority 1) or trigger LED 1–4 when true peak exceeds the threshold; dBTP ceiling peg uses that threshold
Audio sources: Local Input (PortAudio), Livewire AoIP multicast, AES67 multicast RTP (SAP or pasted SDP)
Shared AoIP Interface for Livewire/AES67 IGMP join (empty = system route)
Livewire: advertised sources listed while Settings are open (239.192.255.3 UDP 4001); pick a name or enter channel 1–32767 (channel N → 239.192.0.0+N UDP 5004, L24/48 kHz stereo)
AES67: SAP discovery on 239.255.255.255 and RFC 2974 224.2.127.254 UDP 9875 while Settings are open; live stream list (None / SAP / pasted SDP); L16/L24 at 44.1/48/96 kHz, meters use the first two channels
Settings Audio Meters tab and CONF:Audio:* keys (source, unit, TooLoud, meter width, LUFS reference, peak hold, display style)

Date display follows the configured Formatting/dateFormat setting
Digital AM/PM clock: midnight displays as 12 (12-hour mapping)
NTP lock LED no longer stays green when the server is unreachable
Autoflash / timedflash LED regression and Web-UI blink
MQTT reconnect and AES67 capture restart stop during application quit

Persist windowed position and size across restarts (Window/geometry); restored when not in fullscreen
OpenWeatherMap city search in Settings: type a city name next to City ID, Find, pick a match
Mask Update Key, MQTT password, and OpenWeatherMap API key; slashed-eye toggle reveals them
Time Source settings tab: Local System Clock, NTP Server, PTPv2 IEEE 1588-2008, or LTC
NTP and PTP steer an independent display clock (monotonic timebase); the OS clock is never set
PTP: software slave on 224.0.1.129 UDP 319/320, configurable interface (independent of AoIP) and domain 0–255
LTC: Leo Bodnar LBE-1110 USB-serial SMPTE reader, or SMPTE LTC decoded from a local PortAudio input (Left/Right); display shows HH:MM:SS:FF, holds last timecode on signal loss
LTC audio uses its own capture device (not Audio Meters / Livewire / AES67); opening the same device for meters and LTC can fail on some hosts
LTC unlock WARN (Clock not LTC synchronized etc.) is optional and off by default; the LTC NOT LOCKED LED always remains
AES67: SAP discovery on 239.255.255.255 and RFC 2974 224.2.127.254 (UDP 9875)
PTP: apply TAI−UTC only when the master announces the PTP timescale (fixes ~37s offset vs software ptp4l)
NTP Check settings moved from General to the Time Source tab
Clock lock LED (bottom right, seconds-LED size): green when the selected time source is locked, red when not; caption PTP LOCK / NTP LOCK / LTC LOCK (or NOT LOCKED)
NTP Server field stays enabled when Time Source is NTP, even if NTP-Check is off
Top-of-Hour countdown for Radio Timer (AIR3): wall-clock synchronized countdown to the next full hour (display format M:SS)
Top-of-Hour: Hotkey T to toggle countdown (stop resets display to 0:00)
Top-of-Hour: API command AIR3TOH:[ON/OFF/TOGGLE] via UDP and HTTP
Top-of-Hour: MQTT topic {base_topic}/air3/toh and status topic air3/toh/state (Home Assistant button via Autodiscovery)
Top-of-Hour: Web-UI "Top of Hour" button for AIR3
Top-of-Hour: topOfHour field in /api/status for air[3]
API: TOGGLE for LED1–4, AIR1, AIR2, and AIR4 (same ON/OFF/TOGGLE pattern as AIR3)
