EverLive wurde in der Version v1.5.0 veröffentlicht - vier Tage nach v1.4.0.

EverLive ist ein Open-Source-Userspace-Treiber für die Capture-Karte AVerMedia Live Gamer 4K (GC573), mit dem sich PlayStation 5, Xbox oder Switch auf dem Linux-Desktop spielen und streamen lassen.

Das Update bringt eine dynamische HDMI-2.0-Receiver-Equalisation, die grüne/weiße Pixelfehler und Audioknacksen bei Quellen über 340 MHz beseitigen soll. Die Startzeit sinkt von ca. 9,5 auf ca. 5,2 Sekunden. Außerdem gibt es eine gehärtete JSON-RPC-IPC-Schnittstelle, stabileres Beenden des Console Hubs und Verbesserungen für die Live Gamer DUO (GC570D).

Änderungen in Version v1.5.0:

Highlights

• Dynamic HDMI 2.0 Receiver Equalisation & Character Error Monitoring (GC573):
  • New gc573_user_rx_eq subsystem driving both IT6664 input and IT6805 capture receivers with active per-lane TMDS Character Error Detection (CED), Decision Feedback Equalization (DFE), and Receiver Sensitivity (RS) sweeps.
  • Completely eliminates green/white pixel speckles and audio crackle on HDMI 2.0 sources exceeding 340 MHz TMDS (e.g. 4K60 RGB at ~593 MHz and 1440p120).
  • Diagnostic [HDMI] TMDS errors B/G/R logging with per-lane error telemetry.
  • Tunable environment overrides: EVERLIVE_NO_AUTO_EQ=1 and EVERLIVE_EQ_INPUT_DFE=0.
• Sub-6s Fast Start-up & Link-EQ Hardware State Caching (GC573):
  • Launch-to-capture startup time reduced by over 40% (from ~9.5 s to ~5.2 s).
  • Active lock polling on the Artix-7 FPGA DDR sampler rather than static delays (~1.6 s lock).
  • Error-free equalization parameters are cached in $XDG_STATE_HOME/everlive/link-eq (~/.local/state/everlive/link-eq), skipping full auto-EQ sweeps whenever the incoming signal remains pristine.
  • Line-buffered, timestamped synchronous logging ([ x.xxx] ...) via gc573_user_log with EVERLIVE_LOG_TIMESTAMPS=0 override.
• Hardened JSON-RPC IPC Engine (jsmn):
  • Replaced manual scanner with an RFC-compliant jsmn parser featuring strict object key-vs-value validation to prevent token collision bugs.
  • New IPC commands wired and verified: toast.show (on-screen OSD toasts), edid.set (live runtime EDID DDC reprogramming without restarts), hotplug (150 ms hardware HPD reset pulses), hdr.exposure (live tonemapping EV exposure adjustment), and audio.channels.set (dynamic layout switching).
  • Comprehensive unit test suite in tests/test_ipc_json.c covering positive, negative, and edge-case tokenization.
• Console Hub Exit Stability:
  • Window and system tray icon are explicitly destroyed before Python shutdown, eliminating core dumps and segmentation faults (corrupted double-linked list / PySide::destroyQCoreApplication).
• Live Gamer DUO (GC570D) Hardening:
  • Modularized IT68051 EDID programmer, hardened userspace VFIO receiver, and resolved MSI interrupt allocation order. Verified on physical hardware by @PolygonPrincess.

Special thanks to contributors @Scyllinice and @PolygonPrincess for their contributions to this release!
