What's Changed in EverLive v1.2.0 🚀

📷 Native Virtual Camera (V4L2 Loopback Sink)

  • Direct Output to OBS / Discord: Real-time raw YUYV capture frames are written directly to /dev/video10 labeled "EverLive Capture" via v4l2loopback (--v4l2 <dev> / --loopback [dev]).
  • Zero Window Overhead: Feeds unscaled, pristine frames directly to OBS Studio, Discord, or FFmpeg simultaneously with the interactive gaming window or completely headless.
  • OBS-Safe Topology: Pre-configured with exclusive_caps=0 so /dev/video10 permanently remains visible in OBS even while no writer is actively streaming.
  • Auto-Retry & Buffer Recovery: Robust auto-retry loop for VIDIOC_S_FMT (throttled to 250 ms) with writer fd reset on -EBUSY, automatically resuming delivery when input resolution changes under active readers without restarting EverLive.

🎙️ Headless Studio Mode

  • Zero Display Overhead: Added --headless CLI flag and dedicated Console Hub button ("Start Studio / Headless (OBS)").
  • Background Streamer: Runs video capture over VFIO, pumps frames to the V4L2 loopback sink, and plays HDMI audio without opening an SDL2 window.
  • Passthrough & Server Rigs: Ideal for TV / monitor hardware passthrough gaming and dedicated Linux streaming PCs.

🔄 Seamless On-The-Fly Mode Switching

  • Dynamic Handover: Instant switching between Gaming Mode and Headless Studio Mode without manual stops (Switch to Gaming Screen ↔ Switch to Studio (Headless)).
  • Protected Handshake: Safe DMA and VFIO device handover with retry guard and double-click prevention.

🔊 Universal Surround Bitstream Audio (Dolby Digital & DTS 5.1)

  • Automatic Across All Profiles: Standard EDID profiles (Default, 1440p120, and 1080p240) now advertise both Linear PCM (up to 8 channels) and compressed Dolby Digital (AC-3 5.1) and DTS 5.1.
  • Plug-and-Play Detection: Continuous content-driven IEC 61937 preamble scanner active by default; zero manual profile switching required when changing audio formats on PlayStation 5 or Xbox.
  • Decoded Stereo Downmix: Hardware-accelerated decoding via libavcodec and stereo downmixing via libswresample.

🎛️ Modernized Console Hub GUI

  • Aspect Ratio Override: Added dedicated dropdown (Auto, 16:9 Anamorphic, 4:3 Retro, Stretch to Fill).
  • Live Audio Format Status: Real-time indicator displaying the detected format (L-PCM 48kHz, Dolby Digital 5.1 -> Stereo, DTS 5.1 -> Stereo, (Muted)).
  • Streamlined UI: Removed obsolete "Render Engine" dropdown and cleaned up redundant badges.

📦 Installer Automations & Module-Free Opt-Out

  • Automatic Setup: install.sh automatically installs and configures v4l2loopback (/etc/modprobe.d/ + /etc/modules-load.d/).
  • Strictly Module-Free Opt-Out: Run ./install.sh --no-loopback to keep your system 100% free of DKMS modules and kernel headers.

Verified on Hardware: PlayStation 5 (1440p120 capture, OBS Virtual Camera /dev/video10, Gaming ↔ Studio handover, Dolby Digital & DTS decoding) on Linux / PipeWire.
