Astounds	e03f40d728	fix error handling, null URLs in templates, and Radio playlist support All checks were successful git-sync-with-mirror / git-sync (push) Successful in 13s Details CI / test (push) Successful in 49s Details - Global error handler: friendly messages for 429, 502, 403, 400 instead of raw tracebacks. Filter FetchError from Flask logger. - Fix None URLs in templates: protect href/src in common_elements, playlist, watch, and comments templates against None values. - Radio playlists (RD...): redirect /playlist?list=RD... to /watch?v=...&list=RD... since YouTube only supports them in player. - Wrap player client fallbacks (ios, tv_embedded) in try/catch so a failed fallback doesn't crash the whole page.	2026-03-27 21:23:03 -05:00
Astounds	22c72aa842	remove yt-dlp, fix captions PO Token issue, fix 429 retry logic All checks were successful git-sync-with-mirror / git-sync (push) Successful in 13s Details CI / test (push) Successful in 52s Details - Remove yt-dlp entirely (modules, routes, settings, dependency) Was blocking page loads by running synchronously in gevent - Fix captions: use Android client caption URLs (no PO Token needed) instead of web timedtext URLs that YouTube now blocks - Fix 429 retry: fail immediately without Tor (same IP = pointless retry) Was causing ~27s delays with exponential backoff - Accept ytdlp_enabled as legacy setting to avoid warning on startup	2026-03-27 20:47:44 -05:00
Astounds	56ecd6cb1b	fix: use YouTube-provided thumbnail URLs instead of hardcoded hq720.jpg All checks were successful git-sync-with-mirror / git-sync (push) Successful in 15s Details CI / test (push) Successful in 58s Details Videos without hq720.jpg thumbnails caused mass 404 errors. Now preserves the actual thumbnail URL from YouTube's API response, falls back to hqdefault.jpg only when no thumbnail is provided. Also picks highest quality thumbnail from API (thumbnails[-1]) and adds progressive fallback for subscription/download functions.	2026-03-27 19:22:12 -05:00
