Digital signage software for Windows, Linux and macOS

Our Electron-based application provides native desktop support across Windows, macOS, and Linux from a single codebase. This ensures a consistent user experience with platform-specific optimizations automatically applied.

For robust and reliable media playback, our Electron app integrates the powerful VLC media player engine. This guarantees compatibility with a vast range of video formats and codecs, providing flawless playback every time.

The system features platform-specific volume control implementations that intelligently adapt to the available audio subsystem, whether it's ALSA, PulseAudio, or other native system APIs.

Our desktop client supports advanced hardware features and includes special optimizations:

• HDMI-CEC control and Wake-on-LAN for remote power management.
• On Raspberry Pi, the player runs in Chromium with a VLC playback sidecar.
• A stuck video decoder on Raspberry Pi 4 restarts in about two seconds instead of rebooting the device.
• Dual-HDMI mirroring: a Raspberry Pi can mirror one output to two HDMI ports.
• Power button support on the player.
• These are key parts of our Hardware Control Features.

The player reads the HDMI bus: the TV’s maker, name and power state. It switches the TV on and off, stays the active source and wakes a TV that fell into standby. The device list shows an unplugged cable and the real TV state, so a panel that has been in standby for days no longer hides behind a player that reports “playing”.

Panels daisy-chained over a serial cable are controlled over RS-232 from the CMS: power on schedules, picture, sound and the panel clock. See video walls and panel control.

A Raspberry Pi or PC player can broadcast a Wi-Fi network for other players. For the first connection, a button press shows a QR code: the installer’s phone joins the player’s hotspot and enters the site Wi-Fi. More in remote field service.

We use `electron-store` for cross-session data persistence, providing a robust and reliable storage mechanism for application settings and cached data on desktop platforms.
