About

Punktfunk is the native Linux client for the punktfunk low-latency desktop and game streaming stack. It discovers hosts on the LAN over mDNS, trusts them via certificate pinning with a SPAKE2 PIN pairing ceremony, and streams HEVC video (GF(2^16) Leopard FEC plus AES-GCM over UDP, with a QUIC control plane) at exactly the requested resolution and refresh rate — no scaling. Features: - Hardware-accelerated HEVC decode (VAAPI zero-copy on AMD and Intel, software fallback) - PipeWire audio playback and microphone uplink - Full gamepad support including DualSense touchpad, motion, adaptive triggers and lightbar (SDL3) - LAN host discovery, TOFU fingerprint pinning and PIN pairing
