Noisy YouTube titles are cleaned for display + storage, raw kept in videos.original_title:
- app/titles.normalize_title: strip emoji/symbols (keep accents), remove trailing SEO hashtag
clusters (keep numeric #3 episode markers), context-aware de-shout (mostly-ALL-CAPS titles ->
Title Case with an acronym whitelist + function-word lowercasing; otherwise only long all-caps
words), collapse repeated punctuation
- applied at enrichment (sync/videos.py) and in the download worker (ad-hoc yt-dlp titles);
catalog downloads inherit the normalized title automatically
- migration 0039: add original_title, preserve raw, rewrite title (generated search_vector
regenerates); reversible via original_title
Backfill on localdev: 122115/273417 titles normalized in ~2 min. Verified in the feed + on
real messy samples (emoji/de-shout/hashtags), accents + acronyms (PS5/AI/USA/PC) preserved.
The progress bar looked broken (95% -> 5% -> recount) because yt-dlp downloads the video and
audio streams separately (each 0->100%) then merges — with no indication of which step is
running. Now:
- worker labels the phase from the stream codecs (video / audio) and via a postprocessor hook
(merging / processing), so the user sees what's happening
- DownloadCenter shows the phase as the status and renders an indeterminate pulse (no bogus %)
during merge/processing; phase i18n en/hu/de
- yt-dlp retries (3) + fragment_retries (5) so transient network blips self-heal instead of
failing the job (seen once as a DNS 'No address associated with hostname' error)
Verified: phase transitions queued -> video -> processing -> done.
A queued/downloading row previously showed the bare video id and no thumbnail because asset
metadata was only filled when the download completed. Now:
- service.populate_from_catalog fills title/uploader/thumbnail/date/duration at enqueue from
our own Video/Channel catalog (0 network cost) — feed downloads look right instantly
- worker fills the same from yt-dlp's info_dict on the first progress event (covers ad-hoc
URLs / catalog misses), best-effort, never fails a download
Verified: a paused feed download now shows its real title, channel, thumbnail and duration.
