Replace the class-level Track.download monkeypatch with a per-job progress sink threaded through dl.result(). The API now reports a single aggregate signal instead of each track's bouncing 0-100%:
- bitrate-weighted completion so video/audio dominate subtitles
- completed_tracks/total_tracks counts and active_tracks labels (e.g. "video 2160p DV", "audio en-US 5.1")
- downloads fill 0-90%; repackaging (when needed) and a "muxing" stage carry it to 100% so post-download work is no longer frozen at 100%
- monotonic throughout (handles the download->decrypt callable reuse)
Also:
- accept "HDR10P" as the canonical API range value ("HDR10+" still works)
- declare AUTH_METHODS opt-in on the Service base
- raise typed APIError (WORKER_ERROR/DOWNLOAD_ERROR) from the worker path
- move the progress helpers to unshackle/core/api/progress.py
* feat(api): live download phase, granular progress, swallowed-failure detection, per-request CDM
- Tee Track.download progress so the job reports real percentage (not just 5/100%) and a
human-readable phase ('downloading video 1080p') via the new job.phase field.
- Detect a swallowed download-worker failure (dl.result() prints 'Download Failed' but
exits 0) and raise, so the job is marked failed instead of completed-with-no-output.
- Per-request CDM override (dl_instance.cdm_override; get_cdm prefers it) so a job can use
a specific CDM device without mutating shared config.
* feat(api): expose service capability flags + auth methods in /services
needs_auth / has_search / has_drm derived from which Service hooks are overridden, and
auth_methods inferred from what the service's authenticate() body references (cookies /
credentials), so clients can show only the relevant auth options per service.
* feat(api): per-request credential injection for downloads
Accept a 'credential' ('user:pass') job parameter and feed it into the credentials map that
dl.get_credentials() reads, so a client can authenticate a download without persisting
anything to disk. (Kept on the deployment branch; the PR branch uses the client-sent path.)
* feat(api): gate per-request CDM override behind serve.cdm_overrides
A per-request `cdm` selects a server-side device, so honour it only when allow-listed.
`serve.cdm_overrides` opts in: a list permits those device names, or `true` permits any
(single trusted client). Unset/false rejects every override with 403, so an arbitrary device
can't be selected by default.
* fix(api): redact credentials and proxy userinfo in serialized job parameters
Job parameters can carry a raw user:pass credential and a proxy URL with embedded userinfo;
mask them wherever parameters are serialized for an API response so secrets don't leak via
the job-detail endpoint. Also read skipped-subtitle / download-failure state from the dl
instance instead of scraping stdout, and drop the dead n_m3u8dl percent branch.
* feat(api): prefer explicit AUTH_METHODS class var over source inference in /services
Inferring auth methods from authenticate() source mostly returns both options because services
call super().authenticate(cookies, credential). Prefer an explicit AUTH_METHODS class var when a
service declares one, falling back to inference.
* style: use plain hyphens instead of em-dashes in comments
* feat(api): gate per-job credentials, isolate caches, scrub error fields
Address review feedback on #113:
- Gate per-request credential/credentials behind serve.allow_job_credentials (default off,
403 when not opted in), mirroring the existing serve.cdm_overrides CDM gate.
- Isolate the token cache per credential: when a per-job credential is set, namespace
config.directories.cache by its hash in the worker, so two clients on the same service
with different credentials can't share a cached session.
- Scrub the credential, its password half, and proxy userinfo out of error_message,
error_details, error_traceback and worker_stderr before they leave via the job-detail API.
- Remove the unused _execute_download_sync in-process path (would have leaked one job's
credential into the shared global config).
- Document serve.cdm_overrides and serve.allow_job_credentials in the example config.
- Add tests for both gates (403 default, allowlist pass) and the parameter/error redaction.
* fix(dl): flag download_failed when result() swallows a worker failure
dl.result() catches a download-worker exception, reports it, and returns
without re-raising so the CLI still exits cleanly. An embedding caller (the
API worker) had no way to tell the title actually failed and would report
the job completed with no output. Expose a download_failed flag, set in the
swallow path, that the worker reads after result() returns.
* feat(api): surface skipped subtitles and pass skip_subtitle_errors
Thread skip_subtitle_errors from the job into dl() so the API can opt into
non-fatal subtitle handling, and report which subtitles were skipped: store
them on the job (dl.SkippedSubtitle dicts) and include them in job details
so a client can tell the user which weren't available.

Replace the hardcoded conversion if/elif in Subtitle.convert with a capability-matrix backend registry (subtitle_convert.py): each backend declares the source->target pairs it supports plus a rank, and run_conversion tries them in order as a real fallback chain. conversion_method pins a backend but still falls back (pin-then-fallback).
- Detect the cross-platform SubtitleEdit 5+ CLI (seconv) and use its --flag syntax for convert, SDH stripping, and reverse-RTL
- Protect styled ASS/SSA from automatic SRT downconversion; honor an explicit --sub-format / sidecar_format
- Read segmented fVTT (wvtt) and fTTML (stpp) directly from fragmented MP4
- Improve ASS/SSA font detection: inline \fn overrides, Format-located Fontname column, @-prefix strip, case-insensitive de-dup; covers SSA too
- Update SUBTITLE_CONFIG.md, example yaml, README; add regression tests and a backend benchmark script
-r HYBRID alone muxed the HDR10/HDR10+ base layer as a standalone output because only the ingredient DV track was flagged hybrid_base_only. The inverse was also broken: HDR10/HDR10+/DV tracks never entered the standalone-deliverable pool, so -r HYBRID,HDR10P only delivered the standalone HDR10+ by accident of the first bug.
- Add Tracks.partition_hybrid_videos: ingredient ranges (HDR10/HDR10+/DV) enter the deliverable pool only when their range is explicitly requested alongside HYBRID; replaces the duplicated filter in dl.py.
- Add Tracks.flag_hybrid_ingredients: any track in the hybrid selection but not in the deliverable selection is flagged hybrid_base_only; replaces and generalises the DV-only dv_is_deliverable special case.
Addresses review feedback on the failed-subtitle handling:
- Fully annotate download_tracks_in_passes and the download_track closure (MyPy strict).
- Replace list[str] skipped_subtitles with a documented SkippedSubtitle TypedDict
(id + language + title) so a client can report which subtitle of which title was
skipped; pin the shape with a contract test.
- Clear DOWNLOAD_CANCELLED in a finally so no failed track leaves it set for later code.
- Document why the subtitle pass must stay sequential (a concurrent pass would silently
drop in-flight subtitles via the cancel event).
- Warn only when a title skipped a subtitle and produced no video/audio/subtitle (was a
loose len(title.tracks) check that ignored chapters/attachments).
- Narrow the over-broad remove() except to ValueError with a debug log.
- Add tests: final-clear on the fatal path, all-subs-skipped keeps video/audio, and
duplicate-language subtitles distinguished by id.
ast.Num/node.n deprecated since Python 3.8; NodeVisitor falls back to visit_Num with a DeprecationWarning per dispatch. Under -W error this surfaced as a misleading fps ValueError in Video.init. Replace with visit_Constant, reject non-numeric constants, and pin parse results for int/fraction/float inputs in a regression test.
A single failing subtitle track previously aborted the whole download. Add an opt-in
--skip-subtitle-errors flag: when set, a Subtitle failure is logged and the track dropped from
the mux while the video/audio still complete (Video/Audio failures stay fatal; default
behaviour is unchanged).
Done at the right layer to avoid the shared-event race: a failed track sets the process-global
DOWNLOAD_CANCELLED event, which makes other in-flight tracks early-return without raising — so a
skipped subtitle could otherwise silently truncate the video/audio that still got muxed. The
download is split into two passes (download_tracks_in_passes): the fatal tracks download
concurrently first, then the skippable subtitles run in a separate sequential pass once nothing
else is in flight, with the event reset before each and at the start of every title. Skipped
languages are recorded on the dl instance (skipped_subtitles) for callers to surface.
Adds tests for the cancel-event interaction (a failing subtitle no longer truncates the
video/audio), the good/bad subtitle mix, the flag-off fatal path, and the per-title reset.
When -r included HYBRID, the dl pipeline only muxed the hybrid output and dropped every other downloaded range. DV was also treated purely as a hybrid ingredient pool, so an explicitly requested DV range never produced a standalone deliverable - only the lowest DV (the RPU ingredient) was selected.
- Select the best DV per resolution as a standalone deliverable when DV is in -r, while still using the lowest DV as the hybrid ingredient (dv_is_deliverable).
- Flag the ingredient-only DV (hybrid_base_only) so it is downloaded for the hybrid build but skipped during standalone muxing.
- Mux every requested range standalone after hybrid processing; build hybrids from deepcopied ingredients so the originals stay muxable.
- Add Tracks.merge_video_selections to de-dup the ingredient/deliverable overlap so a shared DV track is not downloaded or muxed twice.
Missing requested subtitle and audio languages now warn and continue when --best-available is set instead of hard-exiting. Without the flag, missing languages still produce an error and exit, matching the prior strict behavior. Audio missing-lang detection is now symmetric with subtitles.
- add find_missing_langs helper in core/utilities for reuse between s_lang and a_lang paths (skips all/best/orig sentinels)
- refactor dl.py s_lang/a_lang checks to share the helper
- add tests/lang_selection covering match primitives, helper output, and tricky langcodes corners (zh-Hans/zh-Hant/zh-CN/zh-TW/zh-HK, cmn/yue, fil/tl/tgl)
- clean up unused-var ruff F841 in tests/remote/unit/
Covers RemoteClient/RemoteService, REST routes, handlers, SessionStore, InputBridge, DownloadQueueManager, errors, compression, and serve CLI. E2e tier opts in via --live and can auto-spawn its own serve.
