yt-dlp already speaks ~1,800 sites; the changes here teach the rest of
the app to route them through platform-specific output folders and
remember where each creator was downloaded from.
New `platform` module
- `Platform` enum: YouTube, TikTok, Twitch, Vimeo, Bandcamp, SoundCloud,
Odysee, Other.
- `classify_url` returns both the source platform and a `UrlKind`
(Channel / Playlist / Video / Unknown) — per-platform path parsing
for each supported host.
- `platform_root(channels_root, platform)` returns the on-disk folder
per platform. YouTube keeps the legacy `channels/` for backward
compat; the others live as siblings (`tiktok/`, `twitch/`, …).
- `write_source_url` / `read_source_url` persist the originating URL
in a `.source-url` sidecar at each creator folder so re-checks no
longer rely on the YouTube-only "UC + 22 chars" heuristic.
Downloader
- `Downloader::start` now takes `&UrlInfo` instead of `&UrlKind` and
routes the yt-dlp `-o` template into the right platform folder.
- For channel downloads it also writes `.source-url` so future
re-checks recover the exact URL.
- Output template uses `%(uploader,channel,creator|Unknown)s` so
non-YouTube sites that don't expose `channel` still get a sensible
creator folder.
- Per-platform `archive.txt` keeps cross-platform IDs (TikTok numeric
vs YouTube base64) from colliding.
- New `recheck_url(&Channel)` prefers `source_url` and falls back to
the legacy YouTube heuristic for libraries created before this
change.
Library scanner
- `scan_channels` now walks every platform's folder and tags each
`Channel` with its `platform` + `source_url`. Sort key puts the
platform first, then name, so the sidebar groups cleanly.
- `Channel` gains `platform: Platform` and `source_url: Option<String>`
fields, populated from the on-disk sidecar.
Web UI
- `WebState` gains `library_root` (= parent of channels_root). The
`/files/` ServeDir is mounted at library_root so non-YouTube videos
resolve at `/files/<platform>/<creator>/<file>`. Existing YouTube
URLs still work — they're now `/files/channels/...` instead of
`/files/...` and the server-rendered JSON updates accordingly.
- Maintenance scan + remove use `library_root` so non-YouTube content
is included.
- `ChannelInfo` JSON exposes `platform`, `platform_label`,
`platform_icon`, and `source_url`.
- Sidebar groups channels by platform with each platform's icon.
- "Check for new videos" now uses the stored `source_url` (with the
YouTube heuristic as a last-resort fallback).
- Download dialog preview shows the detected source + destination
folder.
Desktop UI
- App gains a `library_root` field mirroring the web side; maintenance
ops scan/remove against it.
- Sidebar channel labels are prefixed with the platform icon for
non-YouTube channels; tooltip carries the platform name.
- Download URL field surfaces both source platform and folder path
preview as you type.
Plex
- Non-YouTube creators get their show folder prefixed with the
platform name (e.g., `TikTok - cooluser`) so a YouTube channel and
a TikTok account with the same name don't collide.
Backward compatibility
- Existing YouTube libraries (`channels/<handle>/...`) are untouched.
New platform folders are created on first run as siblings.
- Channels without a `.source-url` (i.e., everything that pre-dates
this commit) fall through to the YouTube heuristic, preserving the
existing re-check behavior.
Tests
- 14 new `platform` tests cover URL classification per platform,
channel handle extraction, and `platform_root` layout. The old
`detect_url_kind` / `extract_after` tests move into platform.rs
since the canonical implementation lives there now.
- 41 unit tests pass.

Bug fixes
- Desktop auto-rescan: snapshot was_running before check_notifications
updates prev_job_states, so the post-download rescan actually fires.
- web::run shutdown: replace `let _ = tx;` (which dropped the sender
immediately and short-circuited the shutdown select!) with
std::mem::forget(tx); add an idle fallback so the `-> !` is honored.
- /api/preview now resolves the bundled yt-dlp path and extends PATH
for deno discovery, matching the rest of the downloader.
- Scheduler interval clamped to >=1h on read so a manually-edited
config.toml with 0 hours can't trigger every tick.
- maintenance::is_within canonicalizes the parent + filename when the
target is missing; remove_files treats NotFound as success.
Security
- Session tokens stored with issued-at Instant and pruned past 30 day
TTL on every touch (was: unbounded HashSet).
- Login rate-limited per source IP: 5 failures → 60s lockout (429).
- Secure cookie flag added when X-Forwarded-Proto: https is present.
- 4 MiB body size cap via DefaultBodyLimit.
- Security headers middleware: CSP, X-Content-Type-Options,
X-Frame-Options, Referrer-Policy.
- JS safeUrl() defangs javascript:/vbscript:/data:text URLs before
interpolation into src= attributes.
- Bundled yt-dlp install verifies SHA-256 against the release's
SHA2-256SUMS; deno hash printed for visual inspection. Install also
reports byte counts every 3s so users see live progress.
- yt-offline.db chmod 0600 at open time on Unix.
New features
- Bundled yt-dlp + deno mode: settings toggle (System/Bundled) plus
one-click Install/Update from settings. Ensures executable bit on
every launch in case the install chmod was missed.
- Download queue with configurable max_concurrent (1–10); pending
jobs surfaced in both UIs.
- Music download mode: --extract-audio into music/<artist>/, separate
sidebar entry, /api/music + /music-files/ endpoints, inline <audio>.
- Download quality selector: Best / 1080p / 720p / 480p / 360p.
- Sort videos by Newest / Oldest (upload_date from info.json with
release_date fallback).
- Plex metadata: per-episode .nfo (title, season/episode, aired,
runtime, plot from .description), <stem>-thumb.jpg symlink, and
show-level tvshow.nfo.
- yt-dlp retry/throttle defaults: --retries 30 --fragment-retries 30
--retry-sleep linear=1:30:2 --sleep-requests 1 to ride out the
"Connection reset by peer" failures.
Performance
- password_required cached in AtomicBool; refreshed only on password
change. Eliminates a SQLite query per static-file fetch.
- Job::log → VecDeque for O(1) front-pop instead of O(n) drain.
- Library scan parallelized across cores via stdlib parallel_map.
- Web UI poll: 600ms while active, 5s when idle, 2s after errors.
- Music scan now recursive (Artist/Album/Track.opus).
- percent_encode_segment uses write! to avoid per-byte String allocs.
Code quality
- 27 unit tests covering parse_progress, parse_stem, extract_after,
detect_url_kind, srt_to_vtt, count_cookies, percent_encode_segment,
bind_mode_of, hash_password, lang_label, is_within, sanitize,
year_of, aired_date, xml_escape.
- Unified library::find_video + Channel::all_videos() iterator,
replacing three duplicated linear searches.
- Downloader::browser wired to --cookies-from-browser as a fallback
when no cookies.txt is present.
- mpv detection now matches the binary basename, not substring.
- Settings modal scroll fix; web settings expose all new fields.
