Fixes#1677 and #1678.
Publishes first-run media tools to the live backend, provides precise cross-platform missing-process guidance, and keeps localized source-language selection available before transcription. Includes regression coverage and deterministic model-store test isolation.
Close unauthenticated remote mutation paths and keep filesystem destinations behind one-shot Tauri capabilities. CodeRabbit and Greptile findings were fixed on-branch; all review threads are resolved. Full CI, Security, Rust, and cross-platform smoke checks are green.
Most users should never learn what ffmpeg is. The Setup Wizard's SYSTEM
PREFLIGHT stops listing FFmpeg / FFprobe / yt-dlp as user-installed
requirements ("brew install ffmpeg…"): they are internal dependencies the
app provisions for itself. Genuine user facts (OS, RAM, disk, GPU,
network, Python) are untouched.
Backend
- New services/media_tools.py: per-tool status {version, path, origin:
sidecar|bundled|system|custom}; background acquisition of a pinned,
SHA-256-verified static ffmpeg+ffprobe build (immutable-commit fetch
from the same upstream the static-ffmpeg pip package uses — that
package itself was audited and rejected: mutable raw/main URL, no
checksums, writes into site-packages); binaries are `-version`-probed
via the existing _binary_runs before being trusted, installed under
DATA_DIR (update-surviving, frozen-build-safe), zero new Python deps.
- ffmpeg_utils resolution chain gains the acquired-bundled tier — and
ffprobe finally has a bundled tier at all (imageio-ffmpeg ships none),
closing the source-install gap.
- New /media-tools router (loopback-gated, same contract as
/system/set-env): status, acquire, {tool}/custom-path | use-system |
restore, ytdlp/update | restore. Overrides persist via the existing
env.FFMPEG_PATH / env.FFPROBE_PATH prefs convention — one store, no
competing controls.
- yt-dlp updates: audited in-venv pip/uv upgrade and rejected (venv is
uv-managed with no pip; yt-dlp is a locked dep, so the updater's
--inexact drift sync would revert it). Instead the newest wheel —
verified against PyPI's own sha256 — lands in a DATA_DIR overlay
prepended to sys.path at startup: survives app updates, works in
frozen builds, and "Restore tested version" is just deleting the
overlay. Gallery now runs yt-dlp via `python -m yt_dlp` (module, not
PATH) so the CLI can never be a user-install task either.
- /setup/preflight drops the three tool rows, carries a media_tools
verdict, and self-heals: kicks the bundled download in the background
when no tier resolves (never re-fires after a failure — the wizard's
card owns Retry). diagnose + the ffmpeg-missing notification now point
at Settings → Audio tools instead of package managers.
Frontend
- Wizard: new MediaEngineCard — renders NOTHING when the engine is ready,
a one-line progress while acquiring, and only on failure an actionable
card (Retry / Use a system copy / Choose file…).
- Settings → Audio tools (new category, System group): FFmpeg + FFprobe
rows with version, path, origin badge, Use system copy / Choose file… /
Restore bundled, header-level "Update bundled build"; yt-dlp row with
Update + Restore tested version (+ restart affordance). Package-manager
commands appear only as copyable prose, never executed.
- The FFmpeg-path override moved out of Settings → Network (pointer row
deep-links to Audio tools; no second writer of env.FFMPEG_PATH).
Notifications gain a settings-tab action type.
- All strings i18n (en + defaultValue), a11y labels on every control.
Tests: 29 new backend (origin classification, checksum/size/probe
rejection, override persistence, overlay update/restore, router gating +
route-shadowing) + preflight contract tests (tool rows gone, verdict
present, auto-acquire fires once); 14 new frontend (wizard hide/progress/
failure-card, Audio tools rows/badges/actions). Route snapshot
regenerated. Docs (macos/linux install, troubleshooting §7b) describe the
new reality in the same commit.
