whisper-cpp: bump to 1.8.4.3 with Android OpenCL + dynamic backends + MSVC fix (QVAC-18300, QVAC-18993) by Zbig9000 · Pull Request #152 · tetherto/qvac-registry-vcpkg

Summary

Day-5 afternoon update (2026-05-21, ~15:40 UTC+2). whisper-cpp PR #28 (QVAC-18993 bundled-ggml — Android dynamic backend) merged into tetherto/qvac-ext-lib-whisper.cpp/master (merge commit f3102199). New commit f287037 repoints the whisper-cpp port REF from the temporary Zbig9000/qvac-ext-lib-whisper.cpp@14620c8857 branch to tetherto/qvac-ext-lib-whisper.cpp@f3102199 and bumps to whisper-cpp 1.8.4.3#5. Source tarball is byte-identical to 1.8.4.3#4 outside parakeet-cpp/ and tts-cpp/ (separate vcpkg ports), so this is a REF-only port-version bump: no recipe change, no patch change, no build-output change. New HEAD f287037.

Day-5 morning (2026-05-21). Dropped the ggml-speech port bump (b4cf7b2) and the ggml-speech-side MSVC shim from this PR. The consumer-side migration to ggml-speech (QVAC-18992) stays open behind qvac-ext-ggml PR #13 and is no longer a prerequisite for the Android dynamic-backend rollout.

Three clean commits on top of tetherto/main:

QVAC-18300 + 18993 — whisper-cpp to v1.8.4.3#3: enables the Android OpenCL feature (Adreno enable-path, COOPMAT[2] disabled), switches Android to full dynamic-backend mode (GGML_BACKEND_DL=ON, GGML_CPU_ALL_VARIANTS=ON, GGML_CPU_REPACK=ON), and adds the spirv-headers dependency under the vulkan feature. Ships patch-free.
QVAC-18993 MSVC fix — whisper-cpp to 1.8.4.3#4: portfile now emits /I<path> on MSVC (and keeps -isystem <path> on GCC/Clang). Surfaced on qvac PR #2124 prebuild / win32-x64: cl.exe doesn't understand -isystem and was trying to compile the include directory path as a .cpp.
QVAC-18993 + 19071 REF repoint — whisper-cpp to 1.8.4.3#5: now that whisper-cpp PR QVAC-4959: Updated qvac-lint-cpp to v1.3.0 #28 (the source of the Android dynamic backend changes) is merged on tetherto/qvac-ext-lib-whisper.cpp/master, flips REPO + REF + SHA512 to point at the canonical upstream merge commit f3102199 instead of the temporary Zbig9000 branch. Drops the "TEMPORARY" comment block from the top of portfile.cmake. Source tarball byte-identical to 1.8.4.3#4 outside parakeet-cpp/ and tts-cpp/ (separate vcpkg ports).

Tasks

QVAC-18300 — Enable OpenCL on Whisper for Android.
QVAC-18993 — Enable Android dynamic backend build.
QVAC-19071 — [Whisper] Update qvac-registry-vcpkg and addon with new port versions (this PR = registry-side half; consumer-side half = qvac PR #2124).

What's NOT in this PR (intentionally)

ggml-speech port bump (was commit b4cf7b2) — kept as open work behind PR QVAC-3127: Updated port qvac-lib-inference-addon-cpp to v0.6.1 #13 + PR QVAC-4959: Updated qvac-lint-cpp to v1.3.0 #28; will land separately once QVAC-18992 (bundled-ggml → external-ggml-speech migration) is finalised. Dropping it from this PR avoids forcing a registry-baseline coupling on consumers that don't need it.
The ggml-speech-side MSVC /I shim (was part of 5cd209c) — folded back into PR QVAC-3127: Updated port qvac-lib-inference-addon-cpp to v0.6.1 #13's portfile.cmake when that lands.

Commit list (HEAD = `f287037`)

378b14f whisper-cpp: bump to 1.8.4.3 with Android OpenCL + dynamic-backend + spirv-headers (QVAC-18300, QVAC-18992, QVAC-18993) — REF + opencl feature + GGML flags + spirv-headers dependency + version 1.8.4.3#3 + baseline.
9f4e8e2 whisper-cpp: fix spirv-headers -isystem shim on MSVC (QVAC-18993) — switches to /I<path> on MSVC. whisper-cpp Updated port qvac-lib-inference-addon-cpp to v0.1.2 #3 → Updated port qvac-lib-inference-addon-cpp to v0.1.3 #4.
f287037 whisper-cpp: bump to 1.8.4.3#5 — repoint to tetherto/master after PR #28 merge (QVAC-18993, QVAC-19071) — REPO Zbig9000 → tetherto, REF 14620c88 → f3102199, SHA512 recomputed, HEAD_REF QVAC-18993-bundled-ggml-android-dynamic-backend → master. whisper-cpp Updated port qvac-lib-inference-addon-cpp to v0.1.3 #4 → Update port qvac-lib-inference-addon-cpp to v0.1.3 #5.

Validation

Local Linux x86_64: vcpkg install whisper-cpp[opencl,vulkan] builds clean against the new baseline.
NDK r29 Android cross-compile: all 7 per-arch libggml-cpu-android_armv*_*.so files produced clean.
OnePlus 7T Pro on-device (Adreno 640): dynamic backend loading works end-to-end — CPU init succeeds (per-arch armv8.2_1 selected by HWCAP), Vulkan & OpenCL backends register and report expected hardware-policy decisions.
Indirect consumer CI (via qvac PR #2124): all 7 prebuild platforms green incl. android-arm64 after the OpenCL fix and the Android ggml_backend_load_all_from_path() fix landed today. Awaiting next run for the post-fix mobile E2E.

Notes for reviewer

REF repoint completed in f287037 (2026-05-21 ~15:40 UTC+2): whisper-cpp port now pulls from tetherto/qvac-ext-lib-whisper.cpp@f3102199 (master HEAD after PR QVAC-4959: Updated qvac-lint-cpp to v1.3.0 #28 merge). The previous Zbig9000/qvac-ext-lib-whisper.cpp@14620c88 pin was a temporary work-around for the unmerged PR chain; it is gone now and the "TEMPORARY pinning" comment block is removed from portfile.cmake.
The patches/ directory is empty; the port is patch-free.
A future 1.8.4.3#6 (or 1.8.4.4) bump under QVAC-19071 will roll the REF forward when the tetherto fork publishes a tagged release or when QVAC-18992 (ggml-speech migration) lands.

Bumps the whisper-cpp port to consume the QVAC-18991 upstream-sync commit on the Zbig9000 fork (https://github.com/tetherto/qvac-ext-lib- whisper.cpp/pull/25), so the transcription-whispercpp on-PR workflow in qvac monorepo can run against the upstream-sync content in isolation (no QVAC-18300 / 18992 / 18993 changes mixed in). Single-purpose validation port: - REF: tetherto v1.8.4.2 -> Zbig9000 47784b9e (PR tetherto#25 HEAD) - SHA512 recomputed from the GitHub tarball - HEAD_REF -> QVAC-18991-pull-latest-whisper-cpp-upstream - version: 1.8.4.2#1 -> 1.8.4.3#0 - No feature changes, no patches, no Android-side configuration changes -- the port is identical in shape to 1.8.4.2#1 except for the source version. This PR is NOT meant to merge to main long-term; it exists to feed a CI run on tetherto/qvac#TBD (QVAC-18991 validation bump of transcription-whispercpp). After CI proves the upstream-sync source is buildable + addon CI is green, this PR is closeable. Production consumption of 1.8.4.3 will go through whisper-cpp PR tetherto#28 + tetherto#27 + this port's regular tetherto#1, tetherto#2, ... port-version chain landing via qvac-registry-vcpkg PR tetherto#152.

…spirv-headers (QVAC-18300, QVAC-18992, QVAC-18993) Brings the whisper-cpp port up to the upstream-sync snapshot at v1.8.4.3 (QVAC-18991, merged into tetherto/qvac-ext-lib-whisper.cpp master via PR tetherto#25) plus the Android speech-stack flags landed for QVAC-18300 + QVAC-18992 + QVAC-18993: - opencl feature (QVAC-18300): Android-only enable-path, OpenCL/Vulkan side-by-side, COOPMAT[2] disabled to keep Adreno-class GPUs healthy. - Android dynamic-backend mode (QVAC-18993): GGML_BACKEND_DL=ON, GGML_CPU_ALL_VARIANTS=ON, GGML_CPU_REPACK=ON. Static dispatcher + per-microarch CPU .so + GPU .so files side by side, picked by ggml's HWCAP-aware loader at runtime. - spirv-headers dependency for the vulkan feature (QVAC-18992): the upstream ggml-org v0.10.2 sync pulled in ggml-vulkan.cpp code that uses spv::* enums unconditionally for SPIR-V capability injection (RTE rounding-mode); Vulkan-Headers no longer bundles spirv.hpp, so the standalone SPIRV-Headers tree must be on the include path. Inject via CMAKE_CXX_FLAGS=-isystem since ggml-vulkan's CMakeLists doesn't find_package(SpirvHeaders). REF currently pins Zbig9000/qvac-ext-lib-whisper.cpp @ 14620c88 which is the tree-equivalent of merged PR tetherto#25 (upstream sync) + merged PR tetherto#27 (tts-cpp <atomic>) + still-open PR tetherto#28 (bundled-ggml Android dynamic-backend fixes). After PR tetherto#28 lands on tetherto/master and a v1.8.4.x tag is published, flip REPO -> tetherto and the tag/SHA (no other port changes needed). The previous port-version 2's two patch files (0001-ggml-allow-backend-dl-with-static-core.patch, 0002-ggml-android-cpu-variant-dlopen-fallback.patch) are now upstream-equivalent commits on whisper.cpp PR tetherto#28 --- ports is patch-free. SHA512 = 733effd6... matches the github.com/Zbig9000/qvac-ext-lib-whisper.cpp/archive/14620c88....tar.gz tarball verified via independent download + sha512sum. version 1.8.4.2 --> 1.8.4.3 port-version 1 --> 3 (continues after the previous port-version 2 patch-based recipe) Co-authored-by: Cursor <cursoragent@cursor.com>

cl.exe does not understand the GCC/Clang `-isystem` flag --- it treats it as a positional argument (a source file path), then tries to open the following include directory path as a source file and dies with: c1xx: fatal error C1083: Cannot open source file: 'C:/.../x64-windows/include': No such file or directory Surfaced on tetherto/qvac/pull/2124 prebuild / win32-x64 against whisper-cpp[vulkan]. The include shim now emits `/I<path>` on MSVC (and the legacy `/I` form, no space, for maximal cl-flavour compatibility) and keeps `-isystem <path>` on GCC/Clang. Note: this PR previously also carried the ggml-speech port bump (b4cf7b2) and the matching ggml-speech-side MSVC shim. Both have been dropped because the consumer-side migration to ggml-speech (QVAC-18992) is staying behind PR tetherto#13 / PR tetherto#28 for now; only the whisper-cpp bits are required to land for the Android dynamic-backend work on PR #2124.

The whisper-cpp source itself is byte-identical between `14620c88` and `f3102199`, so this is a REF-only port-version bump: same recipe, same features, same patches list (still empty), same build output. Also drops the "TEMPORARY pinning to Zbig9000 fork" block from the top of `portfile.cmake` --- no longer applicable now that the upstream PR chain has landed. Closes the registry-side half of [QVAC-19071](https://tetherapp.atlassian.net/browse/QVAC-19071) ("Update qvac-registry-vcpkg and addon with new port versions") for this release cycle. Consumer-side half (re-pinning `packages/transcription-whispercpp/vcpkg-configuration.json`) goes into qvac PR #2124 in a follow-up commit.

…history, drop comment block) Review comments from @GustavoA1604 on PR tetherto#152 (tetherto#152): 1. `ports/whisper-cpp/portfile.cmake`: "Dont add these comments" -> dropped the 19-line header that explained the REF history / tetherto vs Zbig9000 fork relation / future-bump notes. 2. `ports/whisper-cpp/vcpkg.json`: "Port version should start from 0, not 5" -> reset `port-version` 5 -> 0. 3. `versions/w-/whisper-cpp.json`: "Add only one entry here, version '1.8.4.3', port-version 0" -> collapsed the three historical `1.8.4.3` entries (port-versions 3, 4, 5 -- intermediate states that were never consumed off-fork) into a single entry at port-version 0 with the new git-tree `b4962d7acd7ce05fce118792a167e7aee36f1eba`. Older versions (1.8.4.2, 1.8.4.1, 1.7.x) untouched. Also synced `versions/baseline.json` whisper-cpp port-version to 0.

…tetherto#152 review fixes) @GustavoA1604 review on [qvac-registry-vcpkg PR tetherto#152](tetherto/qvac-registry-vcpkg#152) requested three changes on the registry side: 1. Drop the explanatory comment block at top of `ports/whisper-cpp/portfile.cmake`. 2. Reset `port-version` 5 -> 0 (treat the tetherto REF repoint as a fresh start, not a continuation of the Zbig9000-branch series). 3. Collapse the three historical `1.8.4.3` entries (`port-version` 3, 4, 5 -- never consumed off-fork) in `versions/w-/whisper-cpp.json` into a single `port-version: 0` entry with the new git-tree. All three landed in PR tetherto#152 commit `ee71ecb`. This commit is the consumer-side mirror: vcpkg-configuration.json default-registry baseline: f2870372965e899ae1f8a221154d2b243a6c3d30 (1.8.4.3#5, pre-review) -> ee71ecb5b286224377313e5a50558d11adbef3ac (1.8.4.3#0, post-review) CHANGELOG entry updated: "1.8.4.3#5" -> "1.8.4.3#0" + note about port-version reset and history collapse + supersession line covers both prior pins (`9f4e8e2` MSVC fix, `f287037` 1.8.4.3#5). No code change in this monorepo --- pure baseline re-pin. The underlying whisper.cpp source bytes are unchanged (REPO + REF + SHA512 in the portfile are identical between `1.8.4.3#5` and `1.8.4.3#0`), so the produced binary is bit-for-bit equivalent.

…c GGML backends (#2124) * transcription-whispercpp: bump to 0.7.1 with whisper-cpp 1.8.4.3#1 (QVAC-18993) Pull in the consolidated vcpkg PR (whisper-cpp 1.8.4.3 #1 + ggml-speech 2026-05-18 #1) that covers four asana tickets: - QVAC-18991: whisper.cpp upstream-sync from ggml-org/master to v1.8.4.3. Adds upstream's VAD streaming API (whisper_vad_detect_speech_no_reset, whisper_vad_reset_state) with a regression test, the macOS Vulkan persistent-pipeline cache, and various BCI / bindings fixes. - QVAC-18300: enables OpenCL on Whisper for Android, gated behind a new `opencl` feature. This package now declares an android-only `opencl` feature that wires through to the whisper-cpp port's opencl feature, so a transcription addon built for android-arm64 can ship the Adreno backend without forcing it on non-Adreno consumers. - QVAC-18992: rebases the speech-stack ggml (qvac-ext-ggml@speech) onto the same upstream v0.10.2 baseline that whisper.cpp's bundled ggml uses, so the QVAC speech stack (whisper + parakeet + tts-cpp) consumes a coherent ggml API surface. No direct dependency from this package -- transitive via other speech-stack addons sharing the Android process. - QVAC-18993: switches the Android build to pure dynamic-backend mode: GGML_BACKEND_DL=ON + GGML_CPU_ALL_VARIANTS=ON on both the whisper-cpp port and ggml-speech port, so the addon's .bare prebuild ships one libggml-cpu-android_armv*_*.so per microarchitecture plus dynamically-loaded libggml-vulkan.so / libggml-opencl.so. ggml's loader picks the highest-feature CPU variant (armv9.2_2 .. armv8.0_1) plus the right GPU backend (Adreno 700+ -> OpenCL, everything else -> Vulkan) at runtime, so a single APK serves the whole device matrix without per-device builds. vcpkg-configuration.json is TEMPORARILY pointed at Zbig9000/qvac-registry-vcpkg.git @ b5a5e199 (= QVAC-vcpkg-speech-stack-android-dynamic-backend HEAD on Zbig9000's fork) because the consolidated port versions don't exist on tetherto/main yet. Once the vcpkg PR lands the default-registry block must be re-pointed back to https://github.com/tetherto/qvac-registry-vcpkg.git with the post-merge tetherto/main SHA as baseline. Devicefarm: the asana asks for GPU testing on mobile to verify S25 picks OpenCL and Pixel 9 picks Vulkan. Those tests live outside this addon (in qvac CI's integration-mobile-test workflow) and depend on device-farm config that I can't validate locally; the addon code side is unchanged in this bump (CPU dispatcher + dynamic backend `.so` files are already wired by the whisper-cpp port's prebuild output, and the JS layer already enumerates ggml_backend_devs at init). * transcription-whispercpp: bump to 0.7.2 with whisper-cpp 1.8.4.3#2 (QVAC-18993) Picks up the Android per-arch CPU dlopen fallback patch added to the whisper-cpp port (mirrors qvac-ext-ggml@speech 9562ed04). Without this, every APK consumer with `useLegacyPackaging=false` (AGP 3.6+ default) would silently lose CPU init: the directory iterator finds nothing inside compressed APK libs, and the existing on-disk filename fallback never composes the per-arch `libggml-cpu-android_armv*_*.so` names that `GGML_CPU_ALL_VARIANTS=ON` produces. Re-pins the Zbig9000/qvac-registry-vcpkg default-registry baseline to 86257dc376ca043c67cc4805ab8d1e74a94b7eda so both whisper-cpp 1.8.4.3#2 and ggml-speech 2026-05-19#0 are reachable. Co-authored-by: Cursor <cursoragent@cursor.com> * transcription-whispercpp: bump to 0.7.3 → whisper-cpp 1.8.4.3#3 (QVAC-18993) Pure follow-up to 0.7.2 -- the two Android dynamic-backend ggml fixes the 0.7.2 release pulled in via vcpkg patches are now upstreamed as commits on tetherto/qvac-ext-lib-whisper.cpp PR #26 ("ggml + tts-cpp Android dynamic-backend overlays") instead of being carried in the vcpkg port's patches/ tree. Plus a tts-cpp `<atomic>` include fix that closes the parallel speech-stack consumer's build under the day-2 ggml-speech merge. Build output is bit-identical to 0.7.2 (whisper-cpp 1.8.4.3#3 SOURCE == 1.8.4.3#2 SOURCE+PATCHES, verified by hashing all libggml-cpu-android_armv*_*.so files from the NDK r29 cross-compile). Registry baseline bumped to 965f5e5a so the new port-version (1.8.4.3#3) is reachable.

With dynamic- backend mode, ggml builds the per-arch CPU + GPU backends as standalone MODULE libraries that ggml dlopens at runtime; upstream ggml's `install(TARGETS … EXPORT)` deliberately skips them, so the consumer's `BACKEND_DL_LIBS` loop in `CMakeLists.txt` referenced targets that don't exist. Wrap the existing loop with a `if(NOT TARGET ggml::${_backend})` fallback that locates the `.so` under `${VCPKG_INSTALLED_PATH}/bin` via `find_library` and materialises a `SHARED IMPORTED` target locally with `IMPORTED_NO_SONAME=TRUE` — then bundle via the existing `INSTALL TARGET` path. Mirrors the pattern that already ships in `packages/diffusion-cpp` for the same Android-dlopen build mode.

Update the default- registry baseline pointer from the old PR #152 HEAD (dffaaf6) to the rebased HEAD (8c6ca188) so the version-resolver still finds `ggml-speech 2026-05-19#3` (now layered on top of the just-landed 2026-04-09#2) and `whisper-cpp 1.8.4.3#3` (unchanged content, correct SHA512).

Co-authored-by: Cursor <cursoragent@cursor.com> * transcription-whispercpp: wire ENABLE_OPENCL so Android prebuilds ship libggml-opencl.so (QVAC-18300) The `opencl` feature was declared in `packages/transcription-whispercpp/vcpkg.json` (gated to `platform: android`) and the `whisper-cpp` port's `opencl` feature correctly enables `-DGGML_OPENCL=ON` on Android — but the consumer's `CMakeLists.txt` only appended `"tests"` and `"vulkan"` to `VCPKG_MANIFEST_FEATURES`. The `opencl` feature was therefore never activated, so vcpkg resolved `whisper-cpp` without `[opencl]`, ggml was built without `GGML_OPENCL=ON`, and the `android-arm64` prebuild silently shipped CPU + Vulkan backends only (no `libggml-opencl.so`) — defeating the entire point of QVAC-18300. Add an `ENABLE_OPENCL` option (default `ON` on Android, `OFF` elsewhere — the `vcpkg.json` feature is `platform: android` gated so non-Android is a no-op anyway) that appends `"opencl"` to `VCPKG_MANIFEST_FEATURES`. Mirrors the `SD_OPENCL` pattern in `packages/diffusion-cpp/CMakeLists.txt` and keeps the GPU-feature wiring uniform across the three GPU backends (Metal auto, Vulkan toggle, OpenCL toggle). After this commit, the `android-arm64` prebuild's `qvac__transcription-whispercpp/` directory should ship `libggml-opencl.so` alongside the existing 7 per-microarch CPU variants and `libggml-vulkan.so`. Co-authored-by: Cursor <cursoragent@cursor.com> * transcription-whispercpp: default ENABLE_OPENCL ON unconditionally (QVAC-18300) Previous commit (6b42bc0) wired ENABLE_OPENCL but gated it on `_qvac_whispercpp_target_os STREQUAL "Android"`, mirroring the existing ENABLE_VULKAN block. CI re-run (26172345624) exposed that the gate is broken: at top-level CMakeLists.txt time, `CMAKE_SYSTEM_NAME` is not yet set --- the bare-make Android toolchain file is loaded by `project()` (which runs *after* the option block), so `_qvac_whispercpp_target_os` falls through to the host OS ("Linux") and ENABLE_OPENCL stayed OFF on the android-arm64 prebuild. Evidence from run 26172345624's android-arm64 build log: `Installing 9/9 whisper-cpp[core,vulkan]:arm64-android@1.8.4.3#4...` ^^^^^^^^ no `[opencl]` ENABLE_VULKAN works only by coincidence: Vulkan is also default-ON on the Linux host detection branch, so the wrong target detection produces the right behaviour. For Android-only features there is no such overlap. Fix: default ENABLE_OPENCL ON unconditionally and let the actual platform gating happen where it can: (1) the `platform: android` clause on the `whisper-cpp[opencl]` dep in `vcpkg.json`, and (2) the `VCPKG_TARGET_IS_ANDROID` check in the `whisper-cpp` portfile that gates `-DGGML_OPENCL=ON`. Adding `"opencl"` to `VCPKG_MANIFEST_FEATURES` on non-Android is a guaranteed no-op because the feature's only dep is platform-gated --- mirrors the layered gating that `whisper-cpp[vulkan]` already uses (the `vulkan` feature's deps are `!osx & !ios` gated and the portfile's `-DGGML_VULKAN=ON` is also target-gated). After this commit, the android-arm64 install plan should resolve as `whisper-cpp[core,vulkan,opencl]` and the prebuild tarball should contain `libggml-opencl.so` alongside the 7 per-microarch CPU `.so`s and `libggml-vulkan.so`.

Stack: abort → ggml_abort+228 → ggml_backend_dev_backend_reg+48 → whisper_init_with_params_no_state+480 → whisper_init_from_file_with_params_no_state+212 → whisper_init_from_file_with_params+48 → WhisperModel::load()+460 Root cause: the addon never called ggml_backend_load_all*(). With the QVAC-18993 GGML_BACKEND_DL=ON build, the bundled ggml-base no longer defines GGML_USE_CPU, so the static ggml_backend_registry ctor registers zero backends. whisper.cpp's first ggml_backend_init_by_type(CPU) returns NULL → ggml_backend_dev_backend_reg(NULL) trips GGML_ASSERT(device). This is the same crash signature on both the pre-OpenCL run 26170576156 and the post-OpenCL run 26173084690, so it is independent of the recent OpenCL enablement. The mobile workflow last passed on tmp-whisper-184-3-validation back on 2026-05-11, which predates GGML_BACKEND_DL=ON. Mirror the pattern used by every other ggml-based addon in the monorepo (packages/{diffusion-cpp,llm-llamacpp,classification-ggml,…}): * CMakeLists.txt — emit BACKENDS_SUBDIR (<bare_target>/<module_name>) compile def via bare_target / bare_module_target. * WhisperConfig — add backendsDir field (sibling of the handler-driven maps so it bypasses WHISPER_CONTEXT_HANDLERS.at()). * JSAdapter — read top-level backendsDir string directly from configurationParams into config.backendsDir. * WhisperModel::load — on __ANDROID__, std::call_once → ggml_backend_load_all_from_path(backendsDir/BACKENDS_SUBDIR) before whisper_init. * index.js — require('bare-path'); pass backendsDir: path.join(__dirname, 'prebuilds') in _load + reload. No diff on non-Android (Linux/macOS/Windows/iOS): ggml's static ctor keeps registering CPU there as before. aiDocs/15-android-mobile-test-crash-fix.md has the full investigation (crash extraction, layered root-cause, why every other ggml addon already does this, follow-ups).

Only the whisper-cpp bump + whisper-cpp portfile MSVC `/I` fix remain. The consumer-side migration to ggml-speech (QVAC-18992 / PR #13) stays open on the speech branch but is no longer a prerequisite for this Android dynamic-backend rollout.

Co-authored-by: Cursor <cursoragent@cursor.com> * transcription-whispercpp: fix cpp-lint failures (clang-format + clang-tidy) The prior CI run skipped cpp-lint entirely because the recent PR commits only touched CMakeLists.txt / CHANGELOG.md. The new ea298cf commit (QVAC-18993 mobile-test fix) added the first C++ diff in this branch, so cpp-lint now runs full clang-format + clang-tidy and surfaces three issues: 1. clang-format: JSAdapter.cpp had a one-line declaration broken across two lines (LLVM PointerAlignment=Left + AlignAfterOpen collapsed it). Reformatted in place. 2. clang-tidy [readability-identifier-naming]: WhisperHandlers.hpp:9 -- local `const int LANG_ID` violates the variable case style. Renamed to `langId` (lowerCamelCase, matches `checkLanguage` two lines above). Latent issue; never reported before because cpp-lint was a no-op on every prior PR commit. 3. clang-tidy [readability-identifier-naming]: WhisperModel.hpp:100 -- unused `set_weights_for_file(span, bool)` stub kept for parity with `transcription-parakeet` (which uses snake_case extensively for this exact API). Renaming would diverge from the parakeet pattern, so suppress with a single NOLINTNEXTLINE rather than touching the API surface. Local repro: `cp packages/lint-cpp/.clang-format packages/transcription-whispercpp/.clang-format` then `git-clang-format --diff $(git merge-base HEAD origin/main) -- packages/transcription-whispercpp` reports `did not modify any files`. The .clang-format copy is normally produced by `packages/transcription-whispercpp/CMakeLists.txt:58 (configure_file COPYONLY)` during CMake configure.

…c GGML backends (#2124) * transcription-whispercpp: bump to 0.7.1 with whisper-cpp 1.8.4.3#1 (QVAC-18993) Pull in the consolidated vcpkg PR (whisper-cpp 1.8.4.3 #1 + ggml-speech 2026-05-18 #1) that covers four asana tickets: - QVAC-18991: whisper.cpp upstream-sync from ggml-org/master to v1.8.4.3. Adds upstream's VAD streaming API (whisper_vad_detect_speech_no_reset, whisper_vad_reset_state) with a regression test, the macOS Vulkan persistent-pipeline cache, and various BCI / bindings fixes. - QVAC-18300: enables OpenCL on Whisper for Android, gated behind a new `opencl` feature. This package now declares an android-only `opencl` feature that wires through to the whisper-cpp port's opencl feature, so a transcription addon built for android-arm64 can ship the Adreno backend without forcing it on non-Adreno consumers. - QVAC-18992: rebases the speech-stack ggml (qvac-ext-ggml@speech) onto the same upstream v0.10.2 baseline that whisper.cpp's bundled ggml uses, so the QVAC speech stack (whisper + parakeet + tts-cpp) consumes a coherent ggml API surface. No direct dependency from this package -- transitive via other speech-stack addons sharing the Android process. - QVAC-18993: switches the Android build to pure dynamic-backend mode: GGML_BACKEND_DL=ON + GGML_CPU_ALL_VARIANTS=ON on both the whisper-cpp port and ggml-speech port, so the addon's .bare prebuild ships one libggml-cpu-android_armv*_*.so per microarchitecture plus dynamically-loaded libggml-vulkan.so / libggml-opencl.so. ggml's loader picks the highest-feature CPU variant (armv9.2_2 .. armv8.0_1) plus the right GPU backend (Adreno 700+ -> OpenCL, everything else -> Vulkan) at runtime, so a single APK serves the whole device matrix without per-device builds. vcpkg-configuration.json is TEMPORARILY pointed at Zbig9000/qvac-registry-vcpkg.git @ b5a5e199 (= QVAC-vcpkg-speech-stack-android-dynamic-backend HEAD on Zbig9000's fork) because the consolidated port versions don't exist on tetherto/main yet. Once the vcpkg PR lands the default-registry block must be re-pointed back to https://github.com/tetherto/qvac-registry-vcpkg.git with the post-merge tetherto/main SHA as baseline. Devicefarm: the asana asks for GPU testing on mobile to verify S25 picks OpenCL and Pixel 9 picks Vulkan. Those tests live outside this addon (in qvac CI's integration-mobile-test workflow) and depend on device-farm config that I can't validate locally; the addon code side is unchanged in this bump (CPU dispatcher + dynamic backend `.so` files are already wired by the whisper-cpp port's prebuild output, and the JS layer already enumerates ggml_backend_devs at init). * transcription-whispercpp: bump to 0.7.2 with whisper-cpp 1.8.4.3#2 (QVAC-18993) Picks up the Android per-arch CPU dlopen fallback patch added to the whisper-cpp port (mirrors qvac-ext-ggml@speech 9562ed04). Without this, every APK consumer with `useLegacyPackaging=false` (AGP 3.6+ default) would silently lose CPU init: the directory iterator finds nothing inside compressed APK libs, and the existing on-disk filename fallback never composes the per-arch `libggml-cpu-android_armv*_*.so` names that `GGML_CPU_ALL_VARIANTS=ON` produces. Re-pins the Zbig9000/qvac-registry-vcpkg default-registry baseline to 86257dc376ca043c67cc4805ab8d1e74a94b7eda so both whisper-cpp 1.8.4.3#2 and ggml-speech 2026-05-19#0 are reachable.

Plus a tts-cpp `<atomic>` include fix that closes the parallel speech-stack consumer's build under the day-2 ggml-speech merge. Build output is bit-identical to 0.7.2 (whisper-cpp 1.8.4.3#3 SOURCE == 1.8.4.3#2 SOURCE+PATCHES, verified by hashing all libggml-cpu-android_armv*_*.so files from the NDK r29 cross-compile).

With dynamic- backend mode, ggml builds the per-arch CPU + GPU backends as standalone MODULE libraries that ggml dlopens at runtime; upstream ggml's `install(TARGETS … EXPORT)` deliberately skips them, so the consumer's `BACKEND_DL_LIBS` loop in `CMakeLists.txt` referenced targets that don't exist. Wrap the existing loop with a `if(NOT TARGET ggml::${_backend})` fallback that locates the `.so` under `${VCPKG_INSTALLED_PATH}/bin` via `find_library` and materialises a `SHARED IMPORTED` target locally with `IMPORTED_NO_SONAME=TRUE` — then bundle via the existing `INSTALL TARGET` path. Mirrors the pattern that already ships in `packages/diffusion-cpp` for the same Android-dlopen build mode. Static backends (any platform that links ggml in directly) still find their imported target via ggml-config.cmake on the first branch, so non-Android prebuilds are byte-identical.

The `opencl` feature was therefore never activated, so vcpkg resolved `whisper-cpp` without `[opencl]`, ggml was built without `GGML_OPENCL=ON`, and the `android-arm64` prebuild silently shipped CPU + Vulkan backends only (no `libggml-opencl.so`) — defeating the entire point of QVAC-18300. Add an `ENABLE_OPENCL` option (default `ON` on Android, `OFF` elsewhere — the `vcpkg.json` feature is `platform: android` gated so non-Android is a no-op anyway) that appends `"opencl"` to `VCPKG_MANIFEST_FEATURES`. Mirrors the `SD_OPENCL` pattern in `packages/diffusion-cpp/CMakeLists.txt` and keeps the GPU-feature wiring uniform across the three GPU backends (Metal auto, Vulkan toggle, OpenCL toggle). After this commit, the `android-arm64` prebuild's `qvac__transcription-whispercpp/` directory should ship `libggml-opencl.so` alongside the existing 7 per-microarch CPU variants and `libggml-vulkan.so`.

CI re-run (26172345624) exposed that the gate is broken: at top-level CMakeLists.txt time, `CMAKE_SYSTEM_NAME` is not yet set --- the bare-make Android toolchain file is loaded by `project()` (which runs *after* the option block), so `_qvac_whispercpp_target_os` falls through to the host OS ("Linux") and ENABLE_OPENCL stayed OFF on the android-arm64 prebuild. Evidence from run 26172345624's android-arm64 build log: `Installing 9/9 whisper-cpp[core,vulkan]:arm64-android@1.8.4.3#4...` ^^^^^^^^ no `[opencl]` ENABLE_VULKAN works only by coincidence: Vulkan is also default-ON on the Linux host detection branch, so the wrong target detection produces the right behaviour. For Android-only features there is no such overlap. Fix: default ENABLE_OPENCL ON unconditionally and let the actual platform gating happen where it can: (1) the `platform: android` clause on the `whisper-cpp[opencl]` dep in `vcpkg.json`, and (2) the `VCPKG_TARGET_IS_ANDROID` check in the `whisper-cpp` portfile that gates `-DGGML_OPENCL=ON`. Adding `"opencl"` to `VCPKG_MANIFEST_FEATURES` on non-Android is a guaranteed no-op because the feature's only dep is platform-gated --- mirrors the layered gating that `whisper-cpp[vulkan]` already uses (the `vulkan` feature's deps are `!osx & !ios` gated and the portfile's `-DGGML_VULKAN=ON` is also target-gated). After this commit, the android-arm64 install plan should resolve as `whisper-cpp[core,vulkan,opencl]` and the prebuild tarball should contain `libggml-opencl.so` alongside the 7 per-microarch CPU `.so`s and `libggml-vulkan.so`. Co-authored-by: Cursor <cursoragent@cursor.com> * transcription-whispercpp: call ggml_backend_load_all_from_path before whisper_init (QVAC-18993) Android mobile-test E2E crashed inside whisper_init_from_file_with_params with SIGABRT on PR #2124 / run 26173084690 (both Pixel 9 Pro + Samsung S25 Ultra, 132 ms after Downloaded model: ggml-tiny.bin). Stack: abort → ggml_abort+228 → ggml_backend_dev_backend_reg+48 → whisper_init_with_params_no_state+480 → whisper_init_from_file_with_params_no_state+212 → whisper_init_from_file_with_params+48 → WhisperModel::load()+460 Root cause: the addon never called ggml_backend_load_all*(). With the QVAC-18993 GGML_BACKEND_DL=ON build, the bundled ggml-base no longer defines GGML_USE_CPU, so the static ggml_backend_registry ctor registers zero backends. whisper.cpp's first ggml_backend_init_by_type(CPU) returns NULL → ggml_backend_dev_backend_reg(NULL) trips GGML_ASSERT(device). This is the same crash signature on both the pre-OpenCL run 26170576156 and the post-OpenCL run 26173084690, so it is independent of the recent OpenCL enablement. The mobile workflow last passed on tmp-whisper-184-3-validation back on 2026-05-11, which predates GGML_BACKEND_DL=ON. Mirror the pattern used by every other ggml-based addon in the monorepo (packages/{diffusion-cpp,llm-llamacpp,classification-ggml,…}): * CMakeLists.txt — emit BACKENDS_SUBDIR (<bare_target>/<module_name>) compile def via bare_target / bare_module_target. * WhisperConfig — add backendsDir field (sibling of the handler-driven maps so it bypasses WHISPER_CONTEXT_HANDLERS.at()). * JSAdapter — read top-level backendsDir string directly from configurationParams into config.backendsDir. * WhisperModel::load — on __ANDROID__, std::call_once → ggml_backend_load_all_from_path(backendsDir/BACKENDS_SUBDIR) before whisper_init. * index.js — require('bare-path'); pass backendsDir: path.join(__dirname, 'prebuilds') in _load + reload. No diff on non-Android (Linux/macOS/Windows/iOS): ggml's static ctor keeps registering CPU there as before. aiDocs/15-android-mobile-test-crash-fix.md has the full investigation (crash extraction, layered root-cause, why every other ggml addon already does this, follow-ups). Co-authored-by: Cursor <cursoragent@cursor.com> * transcription-whispercpp: re-pin vcpkg baseline to cleaned PR #152 head (QVAC-18993) PR #152 (qvac-registry-vcpkg) was rebased today to drop the ggml-speech port bump (b4cf7b2) and the matching ggml-speech-side MSVC shim. Only the whisper-cpp bump + whisper-cpp portfile MSVC `/I` fix remain. The consumer-side migration to ggml-speech (QVAC-18992 / PR #13) stays open on the speech branch but is no longer a prerequisite for this Android dynamic-backend rollout. New PR #152 HEAD: 9f4e8e20072d8a7a1e118a49c36aacf6af6b3e0d Old (pre-cleanup): 5cd209c145a1d61636f1d44b4afe37868c298a8c This addon does not depend on `ggml-speech` (it consumes the bundled ggml inside `whisper-cpp`), so the dependency closure is unchanged. Updated CHANGELOG to record the new baseline + the reason ggml-speech got dropped. Co-authored-by: Cursor <cursoragent@cursor.com> * transcription-whispercpp: fix cpp-lint failures (clang-format + clang-tidy) The prior CI run skipped cpp-lint entirely because the recent PR commits only touched CMakeLists.txt / CHANGELOG.md. The new ea298cf commit (QVAC-18993 mobile-test fix) added the first C++ diff in this branch, so cpp-lint now runs full clang-format + clang-tidy and surfaces three issues: 1. clang-format: JSAdapter.cpp had a one-line declaration broken across two lines (LLVM PointerAlignment=Left + AlignAfterOpen collapsed it). Reformatted in place. 2. clang-tidy [readability-identifier-naming]: WhisperHandlers.hpp:9 -- local `const int LANG_ID` violates the variable case style. Renamed to `langId` (lowerCamelCase, matches `checkLanguage` two lines above). Latent issue; never reported before because cpp-lint was a no-op on every prior PR commit. 3. clang-tidy [readability-identifier-naming]: WhisperModel.hpp:100 -- unused `set_weights_for_file(span, bool)` stub kept for parity with `transcription-parakeet` (which uses snake_case extensively for this exact API). Renaming would diverge from the parakeet pattern, so suppress with a single NOLINTNEXTLINE rather than touching the API surface. Local repro: `cp packages/lint-cpp/.clang-format packages/transcription-whispercpp/.clang-format` then `git-clang-format --diff $(git merge-base HEAD origin/main) -- packages/transcription-whispercpp` reports `did not modify any files`. The .clang-format copy is normally produced by `packages/transcription-whispercpp/CMakeLists.txt:58 (configure_file COPYONLY)` during CMake configure. [QVAC-18993][QVAC-19071] Co-authored-by: Cursor <cursoragent@cursor.com> * transcription-whispercpp: reference QVAC-19071 in CHANGELOG QVAC-19071 ([Whisper] Update qvac-registry-vcpkg and addon with new port versions) is the meta task that bundles the registry-side port bump (qvac-registry-vcpkg PR #152: whisper-cpp 1.8.4.3#4) with the consumer-side addon bump (qvac PR #2124: transcription-whispercpp 0.7.3, baseline re-pin). No code changes; the work itself was already covered by PR #152 + this PR. Adds the cross-reference so the Asana ticket can be closed off this release cycle. The QVAC-18992 ggml-speech migration (PR #13 + ggml-speech port bump) stays deferred per the 2026-05-21 plan; it will land as a follow-up port bump under the same QVAC-19071 umbrella. [QVAC-19071] Co-authored-by: Cursor <cursoragent@cursor.com> * transcription-whispercpp: re-pin baseline to consume whisper-cpp 1.8.4.3#5 (REF flipped to tetherto/master) [whisper-cpp PR #28](tetherto/qvac-ext-lib-whisper.cpp#28) (QVAC-18993 bundled-ggml --- Android dynamic backend + per-arch CPU dlopen fallback) was merged today (2026-05-21, merge commit `f3102199` on `tetherto/qvac-ext-lib-whisper.cpp/master`). With it merged, `tetherto/master` now carries every commit the registry's `whisper-cpp` port previously pulled from the temporary `Zbig9000/qvac-ext-lib-whisper.cpp@14620c8857` branch: - PR #25 (QVAC-18991, upstream whisper.cpp sync) --- merged 2026-05-20 - PR #27 (QVAC-18966, tts-cpp chatterbox <atomic> fix) --- merged 2026-05-20 - PR #28 (QVAC-18993, ggml-backend android dynamic backend) --- merged 2026-05-21 [qvac-registry-vcpkg PR #152](tetherto/qvac-registry-vcpkg#152) HEAD (`f2870372`) bumps `whisper-cpp` to port-version `1.8.4.3#5` with the REF repoint --- byte-identical source tarball outside `parakeet-cpp/` and `tts-cpp/` (separate vcpkg ports). This commit just re-pins the consumer-side baseline so the addon resolves against the new port-version. vcpkg-configuration.json default-registry baseline: 9f4e8e20072d8a7a1e118a49c36aacf6af6b3e0d (MSVC fix only, whisper-cpp 1.8.4.3#4) -> f2870372965e899ae1f8a221154d2b243a6c3d30 (+ whisper-cpp 1.8.4.3#5 REF repoint) No code change in this monorepo --- pure baseline re-pin. CHANGELOG updated to record both the new baseline and the (now superseded) intermediate `9f4e8e2` pin. Closes the consumer-side half of [QVAC-19071](https://tetherapp.atlassian.net/browse/QVAC-19071) ("Update qvac-registry-vcpkg and addon with new port versions"). Registry-side half = vcpkg PR #152 commit `f287037`. [QVAC-18993][QVAC-19071] Co-authored-by: Cursor <cursoragent@cursor.com> * transcription-whispercpp: re-pin baseline to whisper-cpp 1.8.4.3#0 (PR #152 review fixes) @GustavoA1604 review on [qvac-registry-vcpkg PR #152](tetherto/qvac-registry-vcpkg#152) requested three changes on the registry side: 1. Drop the explanatory comment block at top of `ports/whisper-cpp/portfile.cmake`. 2. Reset `port-version` 5 -> 0 (treat the tetherto REF repoint as a fresh start, not a continuation of the Zbig9000-branch series). 3. Collapse the three historical `1.8.4.3` entries (`port-version` 3, 4, 5 -- never consumed off-fork) in `versions/w-/whisper-cpp.json` into a single `port-version: 0` entry with the new git-tree. All three landed in PR #152 commit `ee71ecb`. This commit is the consumer-side mirror: vcpkg-configuration.json default-registry baseline: f2870372965e899ae1f8a221154d2b243a6c3d30 (1.8.4.3#5, pre-review) -> ee71ecb5b286224377313e5a50558d11adbef3ac (1.8.4.3#0, post-review) CHANGELOG entry updated: "1.8.4.3#5" -> "1.8.4.3#0" + note about port-version reset and history collapse + supersession line covers both prior pins (`9f4e8e2` MSVC fix, `f287037` 1.8.4.3#5). No code change in this monorepo --- pure baseline re-pin. The underlying whisper.cpp source bytes are unchanged (REPO + REF + SHA512 in the portfile are identical between `1.8.4.3#5` and `1.8.4.3#0`), so the produced binary is bit-for-bit equivalent.

Drop the addon-side opencl/vulkan feature sections; CMake no longer carries ENABLE_OPENCL / ENABLE_VULKAN option indirection. - index.js: nest backendsDir under whisperConfig (mirrors parakeet's parakeetConfig.backendsDir). Strip it from the wire-format whisperConfig map and surface it as top-level configurationParams.backendsDir before handing the config to the addon. Fix the stale _createAddon JSDoc that still described "LLM-specific settings". - index.d.ts + README.md: document whisperConfig.backendsDir; drop the ENABLE_VULKAN build instructions (now controlled by vcpkg.json). - Compact all the addon-side comments (CMakeLists.txt, JSAdapter.cpp, WhisperConfig.hpp, WhisperModel.cpp); drop every QVAC asana ticket reference; standardise the C++ log wording on "configurationParams.backendsDir". - Drop "-D ENABLE_VULKAN=OFF" from the test:cpp:build / coverage:cpp:build npm scripts (no-op now that the option is gone).
