…ock (livekit#90) ## Problem On iOS the six `RTCAudioDeviceModule` delegate callbacks in `AudioDeviceModuleObserver` block the native audio worker thread on `dispatch_semaphore_wait(..., DISPATCH_TIME_FOREVER)` while waiting for a JS reply. If the JS thread is at the same time parked inside a blocking-synchronous bridge call (for example `peerConnectionAddTransceiver`, which runs `dispatch_sync(workerQueue)` into libwebrtc and back onto the worker thread that is running this delegate), the reply never arrives and the app freezes permanently. There is no crash, every React Native touchable goes dead, and the only recourse is force-killing the app. In practice this is triggered by publishing a microphone track and then a camera track back-to-back right after connect, or by subscribing to a remote audio-plus-video peer on join. The mic publish flips the engine from playout-only to duplex, and the camera publish issues the synchronous `addTransceiver` that lands in the same few-millisecond window. Refs livekit/client-sdk-react-native#389 and livekit#89. ## Fix 1. Bound each of the six waits to 2 seconds instead of waiting forever. On timeout the observer logs through `os_log` and returns the default value of 0 (proceed), so the engine operation degrades gracefully instead of deadlocking. The timeout itself is what breaks the circular wait, because it releases the worker thread. 2. Add a request-id echo so a late reply from a round that already timed out cannot be misattributed to the next round. Native stamps every event with a monotonic id, JS echoes it back on resolve, and the observer only accepts a resolve whose id matches the in-flight round. A small pre-send drain covers the narrow case where a matching reply signals just past its round deadline. Returning 0 on timeout rather than an error code is intentional. A non-zero return makes libwebrtc roll back the engine operation, and the callers in `AudioState` do not retry and ignore the `StartRecording` return value, so an error would leave audio silently broken with no recovery. Returning 0 also matches the existing behavior when no JS handler is registered. ## Scope Fully contained in this package. The request-id stays internal to `react-native-webrtc` and is stripped before the app-facing handler runs, so the public handler API is unchanged and no changes are needed in `@livekit/react-native`. ## Testing - `tsc --noEmit` and `eslint --max-warnings 0` pass. - Not yet built in a host app. Compilation and a real-device repro of the publish race are still to be done.
Adapt the voice-processing setter/getter to the 144.7559.10 API.
…gistered (livekit#91) ## Summary Builds on livekit#90 (the bounded-wait deadlock fix) to remove the JS round-trip entirely for AudioDeviceModule engine hooks that have no registered handler, instead of only bounding the wait. For those hooks this closes the deadlock window rather than capping it at 2 seconds. Stacked on livekit#90. This PR targets the livekit#90 branch, so it should land after livekit#90 and the diff here is only the delta on top. ## Background livekit#90 bounds each of the six RTCAudioDeviceModule delegate waits to 2 seconds so a stuck JS thread can no longer freeze the app forever. But a hook with no JS handler has nothing to wait for, so blocking it at all is pure risk with no benefit. ## Change Track per-hook handler registration with is-prefixed BOOL active flags. The JS layer pushes a flag to native whenever a handler is set or cleared. When a hook is inactive the observer returns 0 immediately without sending the event or waiting, so the unhandled hooks never enter the blocking path and cannot contribute to the deadlock. In stock config this removes engineCreated, willStart, didStop and willRelease from the blocking path entirely, including willStart, which appeared in both reported freeze traces. The two hooks LiveKit registers by default (willEnable and didDisable) keep the bounded-wait and request-id safety net from livekit#90. The flags are written on the JS thread (handler registration) and read on the native audio thread (delegate callbacks), so they are declared atomic. The multi-field request-id state stays under @synchronized because it needs a true critical section. ## Scope Self-contained in this package. The active flags and request ids are internal to react-native-webrtc and never reach app handlers, so the public handler API is unchanged and no changes are needed in @livekit/react-native. ## Testing - npm run lint (eslint and tsc) passes. - clang-format check passes. - iOS and Android native builds run in CI. Refs livekit#89, livekit/client-sdk-react-native#389.

…er (livekit#96) ## Summary Adds an iOS-only API that pushes the default audio-session policy to native once. When no custom JS handlers are registered, `willEnableEngine` and `didDisableEngine` now configure `AVAudioSession` on the native worker thread. This removes the JS round trip from the default path and the circular-wait risk described in livekit#89. Custom JS handlers still take precedence and keep the bounded timeout. Native activation tracking handles normal stop, interruptions, and external deactivation. Switching between native and custom management during an active call remains unsupported. Switch while disconnected. ## Testing - Built for iOS device and simulator with Xcode 26.6 and WebRTC-SDK 144.7559.10 - Smoke tested on device with CallKit and RNCallKeep through connect, mic publish, mute, and disconnect - Observed no freeze, bridge-wait timeout, or native configuration failure - Confirmed the audio session returned inactive after teardown Current iOS CI failure is unrelated to this change. The React Native 0.71 example fails while compiling Yoga after `macos-latest` moved to macOS 26, before the native code from this PR is compiled. ## Before undrafting - [ ] Add a regression test for the livekit#89 circular-wait shape - [ ] Repeat the device smoke test with the final decision logs Companion PR: livekit/client-sdk-react-native#434 --------- Co-authored-by: davidliu <davidliu@deviange.net>
a312ef9 feat(ios): configure the default audio session natively in the observer (livekit#96) ( Hiroshi Horie 2026-07-23 22:33:50 +0900)
Some hosts forward Activity results to every registered ActivityEventListener more than once (react-native-navigation is a common example). During the getDisplayMedia() screen-capture permission flow this makes onActivityResult fire twice for a single request: the first pass consumes displayMediaPromise (resolving it and nulling it) and the second pass calls resolve()/reject() on the now-null promise, crashing with a NullPointerException. It also spins up a second MediaProjection virtual display. Add null-guards so a duplicate dispatch is ignored: one at the top of the PERMISSION_REQUEST_CODE branch (covers the cancel path, which nulls the promise synchronously) and one at the top of createScreenStream() (covers the success path, since the single-threaded executor runs the duplicated callbacks in order).
The typescript target builds with `tsc --emitDeclarationOnly`, and tsc never
emits output for .d.ts inputs, so src/vendor/event-target-shim/index.d.ts never
made it into lib/typescript. Every `import from './vendor/event-target-shim'` in
the shipped declarations then failed to resolve, which silently stripped the
EventTarget members off our classes for consumers using the declaration files:
error TS2339: Property 'addEventListener' does not exist on type
'RTCPeerConnection'.
skipLibCheck (on by default in react-native's tsconfig) hides the resolution
error itself, so it only ever surfaced at the call sites.
The commonjs and module targets mishandle the same file in the other direction:
they compile every source file and rewrite the extension to .js, emitting an
index.d.js which holds no code and which nothing imports.
Fix both in a postbuild step, since bob 0.18.2 can neither copy extra files into
the typescript output nor exclude files from the babel targets.

In `@ios/RCTWebRTC/VideoCaptureController.m`:
- Around line 55-85: The Center Stage configuration in VideoCaptureController
must be coordinated across all active controllers because
AVCaptureDevice.centerStageEnabled and centerStageControlMode are shared.
Introduce or reuse a shared coordinator to track controller requirements, only
disable Center Stage when no active controller needs it, and update the
format-selection and frame-rate logic to consume the coordinator’s state rather
than reading shared device properties directly. Then run the project formatter
and compile the GumTestApp iOS and Android examples.
In `@src/MediaStreamTrack.ts`:
- Around line 251-255: Update the constraint handling in MediaStreamTrack so the
caller-owned constraints object is never mutated: clone the requested
constraints, apply the facingMode fallback to a separate effective clone used
for normalization, and persist the requested clone only after successful
processing so getConstraints() remains isolated from later caller mutations and
frozen or sealed inputs are supported.
- Around line 251-255: Serialize consecutive applyConstraints and _switchCamera
operations so each constraint update, including facingMode fallback
normalization and this._settings refresh, observes the latest completed state.
Prevent a later call that omits facingMode from injecting a stale value while an
earlier native operation is pending, and add a regression test covering
consecutive _switchCamera and applyConstraints calls.

The cherry-picked facingMode preservation assigned straight onto the caller's
constraints object, which threw on a frozen input and leaked the injected
facingMode back to the caller. It also stored that same object in _constraints,
so getConstraints() aliased something the caller could mutate afterwards.
Apply the fallback to a copy instead. Observable behaviour is unchanged: the
undefined case still normalizes as 'video: true' and still records {}.

… track (GetStream#61) * Custom video track (Phase 1): API contract, skeletons + concepts doc Adds the public TypeScript surface for a custom video track primitive that lets apps feed their own GPU/CPU-rendered frames into a WebRTC video track: - createCustomVideoTrack({width,height,poolSize}) and pushCustomVideoFrame(frame) signatures with thorough JSDoc; stub bodies (filled in a follow-up). - Types: CustomVideoTrackInit, CustomVideoBuffer (surfaceHandle as bigint), CustomVideoTrack, CustomVideoFrameFence ({handle, signaledValue} bigints, documented as platform GPU-sync primitives — MTLSharedEvent / sync-fd — not tied to any GPU library), CustomVideoFramePush. - Barrel exports in src/index.ts (mirrors AudioExtraction). - common/cpp/fishjam-video/FJVideoPushJSI.h: JSI core header (install + a registered platform deliver callback) modelled on FJAudioSinkJSI.h. - docs/custom-video-track.md: concepts + per-frame flow + abstraction-level guide. New-Architecture only (per-frame push is a JSI binding). Handles are bigint end-to-end in the public API; the bridge's string transport stays internal. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Custom video track (Phase 2): shared JS implementation Fills the createCustomVideoTrack/pushCustomVideoFrame bodies and adds the JSI install lifecycle, mirroring the in-tree AudioExtraction.ts: - ensureInstalled(): memoized install of the JSI binding via WebRTCModule.installCustomVideoJSI(), 10s timeout, E_NO_JSI/timeout mapped to a clear 'Custom video tracks require the New Architecture.' error. - createCustomVideoTrack(init): ensure install, call the native bridge method, wrap {streamId, track} into a MediaStream, and convert each bridge string surfaceHandle to a bigint (public type) — the string stays internal. - pushCustomVideoFrame(frame): guard + call the installed JSI global global.__fishjamWebrtcPushCustomVideoFrame(frame). - Named internal bridge types (BridgeCustomVideoTrack / BridgeCustomVideoBuffer) describe the wire shape, distinct from the public bigint/MediaStream types. References native methods landing in the platform phases; tsc + eslint clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Custom video track (Phase 3): shared C++ JSI core Implements common/cpp/fishjam-video/FJVideoPushJSI.cpp (modelled on FJAudioSinkJSI.cpp): install() hops to the JS thread via the CallInvoker and sets a global __fishjamWebrtcPushCustomVideoFrame(frame) HostFunction. The handler runs synchronously (the JS thread is the caller — no thread-hop), unmarshals the frame object (trackId/bufferIndex/timestampNs/rotation as values, the optional fence {handle, signaledValue} as bigint->uint64), and forwards to a platform-registered deliver callback. Absent fence => 0/0 (immediate delivery). weak_ptr capture + expired guard; idempotent reinstall on JS reload. Aligns the header comment to the canonical global name. Compiles when first built into a platform (Phase 4 iOS). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Custom video track (Phase 4): iOS vertical iOS native side of the custom video track, verified streaming on a physical iPhone (color-cycle -> remote peer): - CustomVideoCaptureController.{h,m}: owns a fixed pool of IOSurface-backed, Metal-compatible BGRA CVPixelBuffers; exposes each surface handle to JS via bufferDescriptors; per frame waits on the MTLSharedEvent fence (handle/value as uint64, fence==0 => immediate) then wraps the buffer in an RTCVideoFrame and delivers to the RTCVideoSource. Drain bookkeeping for clean teardown. - WebRTCModule+CustomVideo.mm: installCustomVideoJSI builds FJVideoPush from self.callInvoker (associated-object box; E_NO_JSI on old arch) and setDeliver routes (trackId,bufferIndex,timestampNs,rotation,fence) to the controller via a weak-self trackId->controller lookup. Mirrors WebRTCModule+AudioSink.mm. - WebRTCModule+RTCMediaStream.m: createCustomVideoTrack takes a {width,height, poolSize} dictionary and resolves {streamId, track, buffers}. - podspec: add common/cpp/fishjam-video to HEADER_SEARCH_PATHS. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Custom video track (Phase 5): Android vertical Android native side of the custom video track, verified streaming on a physical device (color-cycle -> remote peer): - Delivery core: AHardwareBufferPool.java + ahardware_buffer_pool.cpp allocate renderable+sampleable AHBs; custom_video_gl.cpp imports each AHB once as a GL_TEXTURE_EXTERNAL_OES (eglGetNativeClientBufferANDROID -> eglCreateImageKHR -> glEGLImageTargetTexture2DOES) and waits the GPU sync-fd fence (eglWaitSyncKHR); CustomVideoFrameDelivery.java drives it on one SurfaceTextureHelper GL thread share-linked to WebRTC's root EGL context, then ships a TextureBufferImpl(OES) VideoFrame via onFrameCaptured -- the same seam the Camera2 capturer uses. - JSI install: FJVideoPushInstaller.{h,cpp,java} (fbjni HybridClass mirroring FJAudioSinkInstaller) builds FJVideoPush from the CallInvoker and routes the deliver callback (fence handle as a long sync-fd) into CustomVideoFrameDelivery. - WebRTCModule.java/GetUserMediaImpl.java: createCustomVideoTrack ({w,h,poolSize} dict) + installCustomVideoJSI gated by CallInvokerHolderImpl (E_NO_JSI on old arch); SDK_INT < O reject before touching the AHB lib. - minSdk kept at safeExtGet(...,24) with __builtin_available(26) guards in the AHB cpp, so the package stays minSdk-24 and only the custom-track path needs 26. - CMakeLists builds the new webrtc-custom-video-track lib (AHB/GL + shared FJVideoPushJSI.cpp + the installer). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * cleanup comments * Custom video track (docs): platform notes + full example - custom-video-track.md: add a Platform notes section (surface pixel format BGRA8 iOS / RGBA8 Android, New-Architecture requirement, Android API-26 floor, fence handles as platform GPU primitives) and link the worked example. - example.md: a complete, annotated color-cycle example end to end -- create the track, import the surface pool into WebGPU, run a fenced 30fps render loop, and publish via useCustomSource -- plus a 'things that bite' section (match the surface format, keep the fence alive, round-robin, same-runtime worklet import, device-only). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Custom video track: harden synchronization, lifetime, and teardown Addresses an independent GPU/media code review. No public API change. Critical: - Android: the GPU fence was waited server-side on the delivery context, which does not gate WebRTC's hardware encoder (it samples on its own EGL context) -> tearing under load. Switched to a client (CPU) wait on the delivery thread (eglClientWaitSyncKHR), so the render is provably complete before any encoder context samples it. Pixels never touch the CPU -- zero-copy preserved. - Android: teardown freed the OES texture/EGLImage/AHB before the encoder was quiesced (no-op TextureBufferImpl release callback) -> UAF. Reordered the custom-video dispose: stop accepting + drain -> dispose VideoSource/VideoTrack -> free GL imports + AHB pool. iOS: - Unified _accepting + _inFlightCount under one lock (was a TOCTOU race -> UAF). - Bounded the stopCapture drain (2s) + _tornDown latch so a never-signaled fence can't deadlock teardown; completions after teardown skip delivery. - CFRetain/CFRelease the borrowed MTLSharedEvent for the armed-listener lifetime. - Deliver the no-fence path off the JS thread; deliver outside the lock (retain the CVPixelBuffer under the lock) so a WebRTC back-pressure stall can't block JS. - Replaced the per-frame cross-thread localTracks read with a lock-guarded weak-value trackId->controller registry. Shared / Android level: - JSI push validates every field and drops a malformed frame instead of throwing on the hot path; clamps rotation to {0,90,180,270}. - Android installCustomVideoJSI gated on API 26 before the native AHB lib loads (keeps the package minSdk 24 safe); re-installs cleanly on JS reload. - Comment/threading-affinity notes; the webgpu Android sync-fd is dup'd by the exporter, so EGL owning+closing it is correct. Builds green on both platforms.
