microphone, and keeps its timers alive. If the failure happens while stopping, it can also upload the failed encoder's partial output.\n\nHandle errors only for the current encoder, release capture and timers before notifying listeners, and transition to `error` once. Resolve the stop gate with the original error so a pending `stop()` rejects without uploading or creating an unhandled rejection. Late events from a destroyed/replaced encoder cannot affect the replacement. The listener-registration cast is reused for unsubscribe to fix the existing strict-TypeScript error while validating this source; this supporting change is identical to #3380/#3387.\n\nValidation: all 41 SDK tests pass. Six new cases cover active/paused failures, timer cleanup, missing native error details, failure during stop, a late old-encoder error, and replacement from an error handler; five fail before the fix. Full SDK strict typecheck and ESM/declaration build, strict new-test typecheck, scoped Biome and diff checks pass.\n\nReproduce: `bun test packages/sdk-recorder`, then `cd packages/sdk-recorder && bun run typecheck && bun run build`.\n\nThis handles capture-time encoding errors; #3380 handles asynchronous upload ownership. Their combined 49-test suite and package typecheck also pass locally after combining their overlapping stop-gate changes. Browser media devices/events are controlled in tests; physical capture and codec failures were not exercised. No dependencies or public signatures change.\n\n\n\n\n\n

Summary

\n\nThe SDK now releases capture and timers when the current encoder fails.\n- Encoder failures release capture and make a waiting stop reject.\n- Listener unsubscribe keeps its existing behavior.\n\nvedanth-jadhav explicitly assigns asynchronous upload ownership to #3380.\n\n\n\nReviews (1) · Last reviewed commit: [\"fix(sdk-recorder): release capture

check", + "body": "# PR Details\n\n## Description\n\nStack 25/39, on top of #134. Follow-up to the 2026-10-18 cleanup audit.\n\n- Under TSAN, each acquire atomic load locks the atomic's sync object; ~100 workers spinning on `activeStripes.load(acquire)` starved the single `fetch_sub(release)` that retires the last stripe, hanging parallel_for (~20% of runs on 112 cores).\n- New `allStripesRetired()` spins on a relaxed load and performs one acquire load once it reads 0; by read-read coherence that load also reads 0, so it synchronizes with all release decrements as before.\n- Zero-cost in normal builds (one extra load on exit); no TSAN-only `#if` needed, and no sleep/yield backoff introduced.\n\n## Test Plan\n\n- clang TSAN (RelWithDebInfo, -fsanitize=thread), `chunked_for_test --gtest_filter=ChunkedFor.SimpleLoopAuto` one process per run, 60 s timeout. Before: 4/20 hung (plus 2 more within ~20 further tries while capturing backtraces). After: 0/60.\n- Backtrace of a hang (gdb): all 113 threads in runStripeWorker; the main thread blocked in __sanitizer::FutexWait under __tsan_atomic32_fetch_sub (the final activeStripes release decrement) while the others spin on __tsan_atomic32_load(acquire).\n- TSAN ctest -R \"for|Chunked|parallel\": 61/61 pass. GCC C++14 Release full ctest -LE flaky: 1287/1287 pass.\n\nThe regrouped stack was verified locally at every PR boundary (GCC 14 Release build of library, tests, examples and benchmarks; `ctest -LE flaky` all pass) and at its tip under ASAN+UBSAN (C++14) and Clang TSAN (all pass), with Doxygen 1.11.0 warning-free. CI's 4-vCPU pool size can't be reproduced locally; CI covers it.\n\n## Types of changes\n\n- [ ] Docs change\n- [ ] Refactoring\n- [ ] Dependency upgrade\n- [x] Bug fix\n- [ ] New feature\n\n## Stable surface\n\n- [ ] Adds to the stable surface, without changing compatibility or behaviour for existing documented use\n- [ ] Alters or removes something present in the most recent tagged release\n- [ ] Alters or removes something added since that release, and not yet shipped\n\n- [ ] Public API or ABI\n- [ ] Default behaviour\n- [ ] A documented concurrency guarantee — ordering, forward progress, cancellation, lifetime or safety\n\nnone.

Six new cases cover active/paused failures, timer cleanup, missing native error details, failure during stop, a late old-encoder error, and replacement from an error handler; five fail before the fix.

\n\nThe SDK now releases capture and timers when the current encoder fails.\n- Encoder failures release capture and make a waiting stop reject.\n- Listener unsubscribe keeps its existing behavior.\n\nvedanth-jadhav explicitly assigns asynchronous upload ownership to #3380.\n\n\n\nReviews (1) · Last reviewed commit: [\"fix(sdk-recorder): release capture after...\"](https://github.com/capsoftware/cap/commit/92cc9220a77f97d784a6a711facda0ee8c53e3e4) · [Reviewed by Greptile](https://www.greptile.com/?utm_source=greptile_review&utm_medium=github&utm_campaign=review_public&utm_content=capsoftware/cap)\n\n", + "body": "When a browser encoder raises `MediaRecorder.error`, the SDK stays in its recording/paused phase, retains the camera and microphone, and keeps its timers alive. If the failure happens while stopping, it can also upload the failed encoder's partial output.\n\nHandle errors only for the current encoder, release capture and timers before notifying listeners, and transition to `error` once. Resolve the stop gate with the original error so a pending `stop()` rejects without uploading or creating an unhandled rejection. Late events from a destroyed/replaced encoder cannot affect the replacement. The listener-registration cast is reused for unsubscribe to fix the existing strict-TypeScript error while validating this source; this supporting change is identical to #3380/#3387.\n\nValidation: all 41 SDK tests pass. Six new cases cover active/paused failures, timer cleanup, missing native error details, failure during stop, a late old-encoder error, and replacement from an error handler; five fail before the fix. Full SDK strict typecheck and ESM/declaration build, strict new-test typecheck, scoped Biome and diff checks pass.\n\nReproduce: `bun test packages/sdk-recorder`, then `cd packages/sdk-recorder && bun run typecheck && bun run build`.\n\nThis handles capture-time encoding errors; #3380 handles asynchronous upload ownership. Their combined 49-test suite and package typecheck also pass locally after combining their overlapping stop-gate changes. Browser media devices/events are controlled in tests; physical capture and codec failures were not exercised.
