1.2.0

1.2.0

Added

• Added Linux-first Qt frontends under clients/Qt/, including Qt Home, a standalone Qt simulator, and a reusable simulator widget.
• Added Qt Home support for compatible app launching, selected-runtime registration on Linux, runtime TOML editing, runtime activity/status display, custom ADB selection, USB reverse mapping setup, and asynchronous transport readiness checks.
• Added Qt simulator video preview with FFmpeg when available, tracking-only fallback when FFmpeg is unavailable, mouse-driven synthetic head tracking, frame-loss/FEC status, and keyframe recovery requests.
• Added Linux Vulkan/FFmpeg runtime scaffolding, portable platform helpers, portable socket helpers, and platform-specific config/state directory support.
• Added first-pass Windows layout and portability scaffolding while keeping the Windows runtime backend non-gating for this release.
• Added canonical shared protocol headers under common/protocol/include/oxrsys/protocol/.
• Added centralized product versioning in config/OXRSysVersion.xcconfig for CMake, Xcode, and Android consumers.
• Added macOS package and distribution helpers: scripts/macos_build_package.sh and scripts/macos_sign_notarize.sh.
• Added the net.demonixis.oxrsys-unity Unity Package Manager package with editor runtime selection and a macOS Player OpenXR loader postprocessor.
• Added runtime tests for portable platform behavior, streaming frame queue replacement, Vulkan dispatch, expanded input handling, protocol layout, runtime status, and loader-backed API behavior.
• Added server-selected headset refresh controls, foveated encoding presets, headset client foveation override presets, Quest shader upscaling controls, and reserved headset-audio configuration to SwiftUI Home and Qt Home.
• Added protocol v1.1 trailing fields for server feature flags, client capability flags, foveated encoding parameters, client foveation, client upscaling, and reserved headset speaker audio.
• Added ALVR-style AADT foveated encoding math, a Metal encoder preprocessing shader, and Quest shader-side foveated-encoding decompression.
• Added a Quest edge-aware shader upscaling path without requiring the proprietary Snapdragon SDK.
• Added configurable Quest client reprojection modes (off, pose, pose_warp) for short decode/network gaps, with displayed-frame-age and reprojection counters in latency reports and runtime status.
• Added a local Quest/PICO shell that replaces standby/loading color clears with a 3D grid, upright status panel, reset button, optional XR_FB_passthrough mode, controller laser interaction, hand laser/pinch interaction, and visible hand-joint markers.
• Added a runtime ABR controller with off, bitrate, and full modes, sliding-window hysteresis, fast bitrate downshift, slow recovery, and profile reporting for future session-safe resolution/foveation/upscaling transitions.

Changed

• Moved the repository toward the OXRSys cross-platform layout, including clients/Android/android-vr/, clients/Apple/common/, and clients/Qt/.
• Changed the runtime graphics plumbing to use typed GraphicsContext and FrameSource data across sessions, swapchains, streaming, and encoders.
• Kept Vulkan loader usage app-owned: the runtime resolves Vulkan entry points from the application-provided dispatch path or already-loaded process symbols without directly linking or loading the Vulkan loader.
• Reworked streaming frame submission around a latest-frame-only queue so replacing a pending frame releases its backend resources.
• Expanded runtime configuration reload behavior for dynamic streaming values while keeping initialization-time resources restart-bound.
• Raised the shared streaming bitrate range to 1 through 200 Mbps and allowed clients to send ClientConnect.maxBitrateMbps = 0 to defer to the server-configured bitrate.
• Updated Apple and Qt simulator clients to avoid imposing their own bitrate cap.
• Updated Apple and Qt simulator clients to own simulator vertical FOV and send it through tracking eye-FOV metadata instead of exposing it through Home runtime config.
• Updated headset client foveation to default to auto, moved headset-side options into dedicated Home sections, and made Quest/PICO XR_FB_foveation apply only when Home sends an explicit override.
• Updated the streaming protocol to carry render-pose metadata per frame and to store the final FEC group packet payload size in the existing video header padding.
• Updated Quest/PICO controller profile handling to stay profile-aware instead of falling back globally to KHR simple_controller.
• Reworked Android VR client transport handling to prefer USB ADB reverse TCP when available, fall back to WiFi UDP discovery, request the build-configured display refresh rate before discovery, and advertise the headset OpenXR system name.
• Updated the Android VR client to request the server-announced refresh rate after discovery, report the active headset rate, advertise streaming capabilities, and apply server-selected client foveation/upscaling options.
• Updated runtime video dispatch so encoded frames pass through a bounded sender queue before WiFi/USB transport writes, keeping socket backpressure out of encoder callbacks.
• Updated the Quest USB ADB client to defer bitrate limits to the server/Home configuration instead of imposing an extra 100 Mbps cap.
• Updated the Quest decoder path to drain MediaCodec output on a decoder thread instead of the XR frame loop.
• Updated the Quest MediaCodec input sizing to keep bounded headroom for high-bitrate foveated-encoding IDR frames.
• Updated the Quest/PICO shell to pause passthrough, stop local shell interactions, and release shell GL resources while streaming video is actively rendered.
• Updated SwiftUI Home and Qt Home with ABR and Quest client reprojection controls plus runtime status display for frame age, ABR state, and reprojection reuse.
• Updated FFmpeg encoder preset mapping so Linux scaffolding maps speed, balanced, and quality to low-latency FFmpeg presets instead of always using ultrafast.
• Updated macOS Home for direct distribution workflows, selected-runtime app launching, runtime registration, package-compatible runtime paths, runtime activity display, and shared Developer simulator integration.
• Updated visionOS streaming behavior around the minimal search window, automatic immersive entry on stream connection, head/hand tracking, and first-pass tracked accessory controller data.

Fixed

• Fixed Metal streaming frame snapshots so the async encoder reads a release-time staging texture instead of a swapchain slot that the app may already have reused. thanks to @wwtssu
• Fixed server-side foveated encoding on Metal by running the AADT pass through a compute shader into a private GPU scratch texture before blitting into the VideoToolbox pixel buffer, avoiding render-encoder validation aborts on the first encoded frame.
• Fixed Quest connection recovery when a server is discovered but no first video frame arrives, returning the client to discovery/retry instead of leaving the standby/loading screen stuck.
• Fixed controller pose handling so streaming packets only update controller poses when the corresponding controller-active flag is present.
• Fixed hand tracking and hand-interaction coexistence so hand bindings remain available while controller bindings keep priority for shared actions.
• Fixed Quest hand tracking ingestion by feeding real XR_EXT_hand_tracking joints from the Android client into the runtime.
• Fixed USB ADB reverse TCP reconnect behavior so closed control/video sockets or video stalls return the Android client to discovery/retry without relaunching the client.
• Hardened Quest USB TCP sends with bounded socket behavior and stale video dispatch cleanup so failed sends do not block encoder callbacks or Session::EndFrame().
• Hardened Quest receive hot paths by reusing TCP/UDP reassembly buffers, avoiding per-packet receive timeout updates, and making USB tracking sends best-effort/non-blocking.
• Hardened Quest headset foveation shutdown by detaching the foveation profile from swapchains before destroying it.
• Hardened runtime-managed Quest logcat capture so it remains optional, bounded, and best-effort during startup.
• Fixed render-pose matching on headset clients so decoded frames are submitted with the pose used to render that frame.
• Filtered known macOS linkd.autoShortcut App Intents diagnostics from Home captured app logs.
• Fixed and covered xrLocateSpacesKHR as an alias for the OpenXR 1.1 xrLocateSpaces entry point.

Documentation

• Reworked platform documentation for build, install, architecture, protocol, Quest/PICO, macOS Home, Qt Home, simulator, visionOS, and testing/conformance workflows.
• Documented current Linux, Windows-scaffold, macOS package, Unity, USB ADB, protocol, and CTS expectations.

Known Limits

• Linux video streaming still needs real Vulkan image readback before it can be treated as feature-complete.
• Windows remains layout and portability scaffolding only for this release.
• PICO and headset-specific controller/hand tracking behavior still needs regular hardware validation.
• Headset speaker audio has protocol/config scaffolding but no active runtime capture/playback pipeline yet.
