HDMI Viewer

HDMI Viewer is an app that allows you to quickly check the input screen and audio status by connecting a UVC HDMI capture dongle via OTG.

On-site, you can check the presence of a signal, resolution (e.g., 1920x1080 60Hz), audio detection, and preview status all on a single screen.

Key Features
• Real-time preview and inspection result determination (Normal/Screen Anomaly/Audio Anomaly/No Signal)
• Create inspection notes, save screenshots, and attach 10-second videos
• Track history via inspection record list/filters
• Settings for app language, default recording length, screen orientation, and audio monitoring

Permissions
• Camera permission: Display UVC video preview
• Microphone permission: HDMI audio monitoring

Permissions are used solely for the purpose of providing the app's inspection functions.
