`POST /video/generate` is reshaped to return a JSON object instead of
a bare string. New fields:
- `playlist_url`: stable hash-keyed URL of the form
`/video/hls/<hash>/playlist.m3u8`. Use this with hls.js / native
players — relative segment refs inside the playlist resolve to
`/video/hls/<hash>/segment_NNN.ts` because the URL is path-based.
- `content_hash`: the blake3 hex digest that identifies the bytes.
Stable across libraries, archive ingests, renames; clients can
cache the URL by hash.
- `ready`: true iff the playlist file is already on disk. False means
a transcode was just queued; the client should retry the URL after
a short delay (or rely on hls.js's built-in retry).
- `playlist` (legacy): basename-keyed path string, echoed under the
old field name so clients that destructure `response.playlist` keep
working during the rollout. The startup migration deletes the
underlying file, so this URL will 404; clients should migrate to
`playlist_url`. Field is slated for removal once Apollo / File
Viewer ship the update.
The handler:
- resolves the source path across libraries (same logic as before),
- looks up `image_exif.content_hash` for that (library_id, rel_path),
- falls back to inline `content_hash::compute` when the row is mid-
backfill — pure read, no library mutation,
- sends a single-element `QueueVideosMessage` to `VideoPlaylistManager`
if the playlist isn't already on disk and there's no
`playlist.unsupported` sentinel,
- returns the URL immediately. The actor pipeline owns transcoding.
New route `GET /video/hls/{hash}/{file}`:
- strict validation: hash must be 64 ascii-hex chars; file must be
`playlist.m3u8` or `segment_NNN.ts` (digits only). Anything else
returns 400 so we never have to rely on path canonicalisation
alone to defend against traversal,
- belt-and-suspenders canonicalize() guard verifies the resolved
file lives under `$VIDEO_PATH`,
- serves with the standard `NamedFile::into_response` machinery.
Cleanup in `actors.rs`:
- `ProcessMessage` + its `StreamActor` handler had no senders after
the rewire — removed. `StreamActor` itself stays (still handles
`RefreshThumbnailsMessage` from `files.rs`).
- `create_playlist`, `playlist_file_for`,
`playlist_unsupported_sentinel` are gone — the legacy on-demand
transcode helper and the migration-only path helpers had no
remaining users (the migration uses its own classify() function).
- Imports tightened: dropped `Child`, `ExitStatus`, `trace`.
Tests cover both new validators (`is_valid_hash`,
`is_allowed_hls_filename`) including the strings that motivated the
defence-in-depth (traversal attempts, internal `.tmp`/`.unsupported`
artifacts, malformed segment names).

Switches the watcher → VideoPlaylistManager → PlaylistGenerator path
from the basename-keyed layout
(`$VIDEO_PATH/{basename}.m3u8`) to the hash-keyed layout
(`$VIDEO_PATH/{hash[..2]}/{hash}/playlist.m3u8`) introduced in the
prior commit. Source videos that share a basename across libraries
(or across subdirs of one library) no longer overwrite each other's
playlists. The legacy HTTP endpoints in `/video/generate` /
`/video/stream` still use the basename layout — those move in a
follow-up commit alongside the stable streaming URL.
actors.rs:
- `QueueVideosMessage.video_paths: Vec<PathBuf>` →
`videos: Vec<VideoToQueue>`. The queue handler dedups against the
hash-keyed playlist + sentinel and forwards `GeneratePlaylistMessage`
carrying the hash.
- `GeneratePlaylistMessage` now carries `content_hash: String`; the
legacy `playlist_path: String` field is gone.
- `PlaylistGenerator` takes a `video_dir: PathBuf` at construction,
computes the hash dir + playlist + sentinel + segment template via
`hls_paths`, `mkdir -p`s the shard/hash dir before ffmpeg runs, and
cleans up partial output on failure by walking the hash dir.
- `ScanDirectoryMessage` and its handler are retired entirely; their
startup-walk role is taken over by the watcher's first tick (see
`watcher.rs` below). Dropping it avoids threading an `ExifDao` into
`VideoPlaylistManager` just so the actor can resolve hashes.
- Legacy `playlist_file_for` / `playlist_unsupported_sentinel` are
retained behind `#[allow(dead_code)]` for the upcoming migration
pass that retires pre-content-hash output.
watcher.rs:
- `process_new_files` keeps `content_hash` in the EXIF-batch result
(formerly threw it away). Videos with `image_exif.content_hash =
NULL` — mid-backfill rows — are skipped this tick rather than
falling back to a basename-colliding playlist; they get picked up
after `backfill_unhashed_backlog` populates the hash on a
subsequent tick. Skipped count is logged at debug.
- The video staleness check now uses `hls_paths::playlist_for_hash`
instead of `$VIDEO_PATH/{basename}.m3u8`.
- `last_full_scan` initialises to `UNIX_EPOCH` so the watcher's first
tick is treated as a full scan. That covers the catch-up gap left
by removing `ScanDirectoryMessage` — every library's existing media
is checked once at watcher boot (≈60s after startup) instead of
waiting up to `WATCH_FULL_INTERVAL_SECONDS` (1h default).
main.rs: removes the `ScanDirectoryMessage` import and the per-library
`do_send` loop, with a comment pointing at the watcher's first-tick
behavior.
state.rs: `PlaylistGenerator::new` now takes the video dir.
Tests: existing `video::hls_paths` (4) and `watcher::tests` (4) pass.
The basename-keyed `/video/generate` endpoint still compiles and
serves; behavior change there is deferred to the follow-up commit.

Foundation for migrating HLS playlist output from basename-keyed
(`$VIDEO_PATH/{basename}.m3u8`) to content-hash-keyed
(`$VIDEO_PATH/{hash[..2]}/{hash}/playlist.m3u8`). The basename layout
collides whenever two source videos share a filename — common with
iPhone-style sequential naming (`IMG_NNNN.MOV`) across libraries — so
the loser's playlist gets overwritten and ffmpeg keeps re-queueing the
file every scan.
This commit adds the path layout and type plumbing without touching the
actor pipeline, watcher, or HTTP handlers yet:
- `src/video/hls_paths.rs`: `playlist_for_hash`, `sentinel_for_hash`,
`segment_template_for_hash` built on top of `content_hash::hls_dir`,
with constants for the filenames inside the hash dir. Unit tests
cover the sharded layout and the playlist/sentinel/segment paths
all landing in the same directory (so HLS relative refs resolve).
- `src/content_hash::hls_dir` un-deaded — was waiting for this branch.
- `VideoToQueue` struct in `actors.rs`: pairs a source path with its
content hash so callers that lack a hash (rows mid-backfill) skip
the video rather than fabricate one.
- `playlist_file_for` / `playlist_unsupported_sentinel` retained as
migration-only helpers — they're only needed by the one-shot startup
pass that retires pre-content-hash output.
Follow-ups (separate commits on this branch): wire `hls_paths` through
the queue handler + `PlaylistGenerator`, update the watcher's
`process_new_files` to build `VideoToQueue`, switch `/video/generate`
and `/video/stream` to resolve path→hash and return stable URLs, add
the legacy-layout migration, rewrite `cleanup_orphaned_playlists` for
the new dir shape, and surface progress via Prometheus + `/hls/stats`.

main.rs drops from 3542 → ~2930 lines by moving:
- src/backfill.rs (new): backfill_unhashed_backlog,
backfill_missing_date_taken, backfill_missing_content_hashes,
build_face_candidates, process_face_backlog. Now unit-tested for
the first time — 5 tests covering cap behavior, library-id
filtering, missing-on-disk skip, and the video/unhashed/scanned
filters on face-candidate selection.
- src/thumbnails.rs (new): unsupported_thumbnail_sentinel,
generate_image_thumbnail, create_thumbnails, update_media_counts,
is_image, is_video, plus the IMAGE_GAUGE / VIDEO_GAUGE Prometheus
metrics. Replaces the no-op stubs that used to live in lib.rs.
4 new unit tests for the sentinel path math and the
walker-counts-images-vs-videos smoke path.
Supporting:
- SqliteExifDao::from_shared (test-only) so an SqliteExifDao and
SqliteFaceDao can share one in-memory connection — required to
test build_face_candidates against the real join.
- files.rs / video/{mod,actors}.rs import from crate::thumbnails::*
instead of the now-removed stubs in lib.rs.
cargo test --bin image-api: 325 passing (was 314).

`get_duration_seconds` now returns `Option<f64>` and falls back from
`format=duration` to `stream=duration`. Empty stdout no longer
parse-panics with "cannot parse float from empty string", which was
poisoning the preview-clip row with status=failed and re-queueing every
full scan (notably for GoPro LRV files). `generate_preview_clip` handles
the unknown-duration case by transcoding the whole file (capped at 10s).
`generate_video_thumbnail` seeks to ~50% of the probed duration instead
of a hardcoded `-ss 3`, with a first-frame fallback when the probe
returns nothing. Fixes the loop where short Snapchat clips (<3s) got
"missing thumbnail" logged on every scan because ffmpeg exited 0
without writing a frame, and never wrote the .unsupported sentinel
either.
Adds unit tests for `parse_ffprobe_duration` covering the empty-output,
N/A, multi-line, non-positive, and non-finite cases.

The bare 'ffmpeg -ss 3 -i in -vframes 1 -f image2 out' command failed on
sources whose decoded pix_fmt isn't yuvj420p (e.g. older Samsung phone
videos in yuv420p). With no -vf filter chain, the decoded frame goes
straight to the mjpeg encoder, which rejects it with 'Non full-range
YUV is non-standard' and exits non-zero.
generate_image_thumbnail_ffmpeg already handles the same class of
source for HEIC/RAW by adding -vf scale=200:-1 -c:v mjpeg — the filter
chain lets ffmpeg auto-insert the pix_fmt converter the encoder needs.
Adopt the same args here. Side benefit: video thumbnails are now 200px
wide on disk, matching image thumbnails (previously full-resolution).
Pre-existing .unsupported sentinels for videos that hit this failure
will need to be deleted manually to retry — they're under
$THUMBNAILS/<lib_id>/.../*.unsupported.

generate_video_thumbnail used .output().expect(...), which only catches
spawn failure — non-zero ffmpeg exits were silently discarded. With no
thumbnail and no .unsupported sentinel left behind, the watcher
re-detected the file as missing every quick-scan tick and re-logged
"New file detected (missing thumbnail)" forever.
Mirror the image branch: return io::Result, check status.success(),
and write the sentinel from create_thumbnails on failure.

Previously a corrupt source (e.g. truncated mp4 with no moov atom) would be
re-queued on every directory scan: cleanup_partial_hls wipes the temp
playlist on ffmpeg failure, leaving no .m3u8 to short-circuit the next pass.
Mirrors the thumbnail .unsupported sentinel pattern: on ffmpeg failure,
write <playlist>.m3u8.unsupported, and treat its presence as "done" in both
the ScanDirectoryMessage filter and the QueueVideosMessage check. Delete
the sentinel to force a retry.

Three recurring issues on every full scan:
1. Video playlist scans re-enqueued every file only to reject it as
AlreadyExists. Pre-filter in ScanDirectoryMessage and QueueVideosMessage
so we skip videos whose .m3u8 already exists, and demote the leaked
AlreadyExists log to debug.
2. image crate was built with only jpeg/png features, so webp/tiff/avif
files logged "format not supported" every scan. Enable those features.
3. RAW (ARW/NEF/CR2/...) and HEIC thumbnails weren't generated, so the
scan kept retrying them. Try the file's embedded JPEG preview via
kamadak-exif first (fast, pure-Rust, works on Sony ARW where ffmpeg's
TIFF decoder fails). Fall back to ffmpeg for HEIC/HEIF and RAWs with
no preview. Anything still undecodable gets a <thumb>.unsupported
sentinel so future scans skip it.

The /photos/gps-summary handler validated the incoming path against
the primary library's root with new_file=false, which requires the
path to exist on disk. For a viewer opened on a file from a
non-primary library, tapping the GPS link produced activePath =
<folder from lib 2>, the primary-only check failed, and the server
400'd — so the map came up empty.
Validation here is purely a traversal guard (the DAO does a prefix
LIKE against rel_path), so we now accept the path as long as any
configured library can resolve it without escaping its root.
Also applies cargo fmt drift on files touched this session.

PreviewClipGenerator stripped a single base_path, so videos in a
non-primary library ended up with the absolute path as 'relative'.
On Windows, PathBuf::from(preview_clips_dir).join(absolute) replaces
with the absolute path, and .with_extension("mp4") on a .mp4 input
yields the input path — ffmpeg then errors out with 'cannot edit
existing files in place'.
The generator now holds Vec<Library> and strips whichever root
actually contains the video, with separator normalization to match
the rest of the code.
