Thread context.Context from main through watcher, encoder, and metadata
clients so a Ctrl-C during a multi-hour encode immediately kills the
ffmpeg/ffprobe/opusenc children instead of waiting for them to finish.
- main: signal.NotifyContext replaces the manual sigChan + done goroutine
- watcher.Start: takes ctx, exits on ctx.Done(); processFn signature is
now func(context.Context, string) error
- encoder: Transcode and every helper (extractAudio, encodeOpus,
encodeVideo, GetMediaInfo, GetStreamLanguages, calculateZscaleWidth)
take ctx; every exec.Command becomes exec.CommandContext so the child
is SIGKILL'd on cancel
- metadata: FetchMovieMetadata, FetchSeriesMetadata, fetchTVMazeJSON
take ctx and use http.NewRequestWithContext
Mover stays ctx-free intentionally: a rename is fast enough that
mid-cancel cleanup is the next-restart's problem. processFile's
deferred RemoveAll(workDir) and failToFailed still run after cancel,
so partial output dies in the work dir and the source moves to failed/.
Source kind is now declared per-file via a `dvd` / `bluray` / `webdl` /
`tvrip` token in the basename (case-insensitive, word-bounded). Matches
the existing `tt…` / `tvm…` filename convention. When no token is
present, falls back to the pixel-count guess in DetectMediaType, which
still only chooses between DVD and Blu-ray.
The parsed media type drives both ORIGINAL_MEDIA_TYPE in the muxed
metadata and the CRF/preset profile used for encoding. EncodingConfig
gains `webdl` and `tvrip` sub-blocks with conservative defaults
(WebDL 30/3, TVRip 32/2); user can override in config.yaml.
Manual updated with the new tokens, config fields, and pipeline
description.
TVmaze: drop trailing slash from base URL (was producing //shows/), send
season/number as plain ints (TVmaze rejects zero-padding), check HTTP
status before decoding so 404 bodies stop being decoded as episodes, and
fetch /shows/{id} separately for show name + IMDb mapping —
episodebynumber does not honor embed=show despite what the docs imply.
OMDb: check HTTP status, and include a body snippet when Response is
non-True with an empty Error field so rate-limit and HTML failure modes
are diagnosable.
Both: assert that the fields we actually depend on come back non-empty
after decode. Catches silent field rename/removal without making us
fragile to TVmaze adding new optional fields.
main.processFile: split the nometadata fallback by branch. Series uses
Collection (legitimate shows can have no IMDb mapping); movies keep the
IMDBID/Title check.
