YouTube increasingly demands a Proof-of-Origin token (or shows 'confirm you're not a bot').
Instead of manual cookies, run the bgutil POT provider as a sidecar that mints tokens on demand:
- compose: bgutil-pot service (brainicism/bgutil-ytdlp-pot-provider:1.3.1, port 4416, init)
- requirements: bgutil-ytdlp-pot-provider==1.3.1 plugin (version pinned to the image)
- config: DOWNLOAD_POT_BASE_URL (http://bgutil-pot:4416) + DOWNLOAD_PLAYER_CLIENTS
(web_safari,web,tv — POT-capable; the default android_vr client never requests a token)
- formats.build_ydl_opts wires extractor_args youtube:player_client + youtubepot-bgutilhttp:base_url
Verified: the sidecar mints a valid PO token (BotGuard challenge solved) and yt-dlp fetches it
from the provider. NOTE: end-to-end download couldn't be confirmed here because the test IP got
hard-flagged by YouTube from heavy testing (~16 GB + dozens of extractions) — a hard abuse block
needs cooldown/cookies, which POT doesn't lift; POT bypasses the normal soft bot-check.
ffmpeg post-steps have no byte-progress, so instead of a silent 'Processing' the row now names
the current step (Merging / Extracting audio / Embedding thumbnail / Removing sponsors / Writing
metadata) with an indeterminate pulse. Byte-progress phases (video/audio) keep the % bar.

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.
