QAnotherRTSP

The cross-platform successor to AnotherRTSP: a lightweight, fast, highly configurable RTSP camera viewer for Windows, macOS and Linux, for people who want to see their cameras without running a full NVR or a surveillance suite that eats a CPU core per lens.

Built in Go + Qt on an FFmpeg backend (H.264/H.265/MJPEG, hardware decoding via VideoToolbox with software fallback). The UI lives in the system tray: one-click per-camera enable/disable, borderless always-on-top windows that magnetically snap and stack into saved formations, multi-monitor support, and live diagnostics overlays — health, FPS, bitrate, dropped frames, CPU — because a camera viewer built by a sysadmin obviously ships with monitoring.

Configuration is a human-readable YAML file with instant apply. GPL-3.0, 100% open source, stable releases on GitHub plus nightly builds.
