Store policy 10.2.2 forbids dynamic code inclusion, and this was the only
third-party binary the app ever downloaded and ran. It had already failed in
production: the pin aged out of BtbN's 14-day retention and the download 404'd
on the creator's first real recording attempt (2026-09-01). Bundling kills
that failure class permanently and deletes the startup network dependency.
- scripts/fetch-ffmpeg.sh populates a gitignored ./ffmpeg from a pinned
month-end BtbN LGPL-shared artifact, SHA-256 verified before extraction,
idempotent, FFMPEG_ZIP= override. 135 MB of DLLs in git would tax every
commit on this 9p tree; the URL + hash are the audit trail LGPL §6 wants.
- ytLive.csproj copies ffmpeg\** to output and publish (Always), and a
GuardBundledFfmpeg target fails the BUILD if the folder is missing, so a
fresh clone finds out before a take rather than during one.
- FfmpegLocator loses the downloader, the zip extraction and the
%APPDATA%\ytLlive\tools cache. Order is now bundle -> PATH, deliberately
inverted: a PATH ffmpeg may be a different major version or a GPL build,
and the bundle is what was pinned, license-vetted and tested. A missing
bundle throws loudly; the old "found something on disk" path could satisfy
a missing bundle with a stale copy, and silent drift is the worst failure
mode for a dependency certification inspects.
- ffplay.exe (18 MB) is not shipped; nothing calls it.
- THIRD-PARTY-NOTICES.txt: "downloads" -> "bundled" throughout, and the stale
build tag autobuild-2026-08-09-13-03 — the tag that 404'd — corrected to
autobuild-2026-08-31-13-27 with the exact artifact name and archive hash.
OpenH264 made precise: compiled INTO avcodec-63.dll, no separate binary.
Checked whether other third-party binaries needed bundling: no. e_sqlite3.dll
and WebView2Loader.dll already ship via NuGet into runtimes\win-x64\native\,
OpenH264 is inside avcodec-63.dll, the rest are managed. Two gaps remain that
bundling cannot fix, recorded in the map: the WebView2 Evergreen runtime is a
machine prerequisite (TASK 48 item 2), and Velopack's updater downloads and
executes, so its teardown is a compliance action.
Tests: 16 locator facts, suite 379/379, 0 warnings. The integration test runs
the bundled ffmpeg -version, which is the only assertion that proves the
sibling libav*.dll resolved — presence checks pass with the DLLs missing and a
shared build then fails to start. TheLocatorCarriesNoNetworkCapability keeps
10.2.2 from rotting back.
