lex-fridman-podcast-s01-yt-import

Second YouTube import into the STOCK Jellyfin at tv.s8n.ru (container jellyfin-stock), this time targeting the Podcasts library. Five episodes of the Lex Fridman Podcast — treated as one Series (Lex Fridman Podcast) on Season 01, with the podcast episode number used directly as the episode index (E400, E461, E478, E479, E481).

Independent from arrflix prod (arrflix.s8n.ru) and arrflix dev. Stock Jellyfin's Podcasts library has EnableInternetProviders=false — files land with filename/folder-only metadata. No TMDb/TVDB matching is expected or attempted. Mirrors the pattern set by benn-jordan-s01-yt-import.md (commit 6e336d1).

Provenance

  • Source: YouTube channel "Lex Fridman" (podcast back catalogue picks)
  • Tool: yt-dlp 2026.03.17 on onyx
  • Format selector (1080p cap): bv*[height<=1080][ext=mp4]+ba[ext=m4a]/b[height<=1080][ext=mp4]/bv*[height<=1080]+ba/b[height<=1080]/b → --merge-output-format mp4
  • Subs: --write-subs --sub-langs "en.*" --embed-subs --convert-subs srt — user-uploaded en subs embedded as mov_text when present (4/5 eps); E478 had no en track on YouTube.
  • Staging path on onyx: /home/admin/staging-jelly/Lex Fridman Podcast/Season 01/
  • Parallel downloads: 5 jobs spawned simultaneously, master wrapper wait-blocked until ALL exited 0 before rsync (lesson from prior run — never race rsync against in-flight downloads).

Total on disk ~4.74 GB across 5 mp4s. The 1080p cap kept the 10.4-hour E478 to 1.7 GB — at 4K this would have ballooned past 50 GB.

Jellyfin's ffprobe is off by 1 s on E461/E478 (rounding-down vs YouTube's declared seconds) — within tolerance, no correction needed.

Stream sample (S01E479)

major_brand     : isom
Duration: 01:50:28.48, start: 0.000000, bitrate: 703 kb/s
Stream #0:0[0x1](und): Video: av1 (libdav1d) (Main) (av01 / 0x31307661), yuv420p(tv, bt709), 1920x1080, 568 kb/s, 30 fps
Stream #0:1[0x2](eng): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 127 kb/s
Stream #0:2[0x3](eng): Subtitle: mov_text (tx3g / 0x67337874), 0 kb/s

AV1 1080p30 ~568 kb/s + AAC stereo ~127 kb/s + embedded mov_text en subs. Source is YouTube's best 1080p mp4/m4a combo. AV1 direct-play requires a recent client (Chromium ≥ 90, Firefox ≥ 100, Apple Silicon Safari, Android 12+, modern smart-TVs); otherwise jellyfin-stock will CPU-transcode (no GPU mount per SYSTEM.md).

Subtitle status

  • Embedded mov_text (en): yes for E400 / E461 / E479 / E481 (user-uploaded en track present on the YouTube upload — yt-dlp embedded via --embed-subs).
  • E478: no en track available on YouTube — no embedded sub. Player will fall back to no subs unless auto-CC sidecar is fetched later (--write-auto-subs --sub-langs "en.*").
  • External sidecar: none.
  • Action: leave as-is for now. If E478 subs become required, re-fetch auto-CC and drop a .eng.srt next to the mp4 per playbooks/subtitles/.

Verification checks

  • Folder/filename canonical (Lex Fridman Podcast/Season 01/Lex Fridman Podcast - S01E<NNN> - <Title>.mp4)
  • Permissions user:user 644 / 755 on nullstone
  • Scan Media Library task triggered via /ScheduledTasks/Running/$SCAN_ID (HTTP 204) — completed at 2026-05-11T14:43:12Z
  • Note: initial scan created Series + Season stubs but ChildCount=0. A follow-up /Items/$SERIES_ID/Refresh?MetadataRefreshMode=FullRefresh&Recursive=true (HTTP 204) was required to actually pull the 5 episodes into the index. This was not required in the benn-jordan run — possibly because Lex's filenames include forbidden-looking characters (, & -) and Jellyfin's series-stub-first heuristic is slower to reconcile when the discovery probe is racing the scan. Documented here so the next operator knows the second-pass refresh is sometimes load-bearing.
  • Per-series query /Shows/$SERIES_ID/Episodes?Season=1 returns 5 episodes with correct durations
  • No /Items/Counts reliance — used /Shows/<id>/Episodes as authoritative
  • [n/a] ProviderIds populated — expected empty, Podcasts library has internet providers OFF
  • ImageTags.Primary populated on all 5 — Jellyfin extracted thumbnail from mp4 itself

Scan task

  • Task ID: 7738148ffcd07979c7ceb148e06b3aed
  • POST result: HTTP 204
  • StartTime (initial scan): 2026-05-11T14:43:01.031Z
  • EndTime (initial scan): 2026-05-11T14:43:12.285Z (11 s)
  • Follow-up series refresh: POST /Items/$SERIES_ID/Refresh returned HTTP 204; episodes appeared in season within ~3 s.
  • State after run: Idle

Notes / surprises

  • Stock Jellyfin's Podcasts library is configured tvshows-type with EnableInternetProviders=false. This matches the Educational library set up for Benn Jordan — same pattern, different folder. Do not try to TMDb-identify Lex Fridman Podcast episodes; the Podcasts library is deliberately offline.
  • Used podcast episode number as the season-1 episode index. E400/E461/E478/E479/E481 is consciously sparse — Jellyfin handles non-contiguous episode numbers fine, and using the canonical podcast number means there's no ambiguity when an operator looks at the UI and matches "Lex #481" to a file.
  • All 5 downloads ran in parallel from onyx via a wrapper script (/tmp/lex-download.sh) which wait-blocked on every job PID before exiting. The wrapper's exit code (0) gated the rsync step — addressing the "rsync raced partial downloads" failure mode from a prior YouTube import.
  • E478 is 10.4 hours (Scott Horton - The Case Against War and the Military Industrial Complex). Capped at 1080p it weighs in at 1.7 GB / ~590 kb/s total. At 4K it would have exceeded 50 GB and absolutely buried disk. The format selector bv*[height<=1080] is now the standing rule for any podcast-style long-form import.
  • rsync ran at ~61 MB/s onyx → nullstone over the 1G LAN (4.7 GB in ~80 s). No --info=progress2 surprises; resumable on disconnect via rsync defaults.
  • Source staging dir on onyx (/home/admin/staging-jelly/Lex Fridman Podcast/) is intentionally left in place — do not delete until owner confirms playback.

Operator action

  1. Open https://tv.s8n.ru → Podcasts library → confirm "Lex Fridman Podcast" series shows 5 episodes (numbered 400 / 461 / 478 / 479 / 481).
  2. Play any episode → confirm direct-play on a modern AV1-capable client (no transcode line in docker logs jellyfin-stock). On older clients expect CPU transcode.
  3. Optional: upload custom series poster + per-episode artwork via the Jellyfin web UI (no TMDb fallback, so artwork is manual or absent).
  4. Source dir on onyx retained per cleanup policy.
