The previous fix rebuilt the quality chain when converting persisted
models back to videos, but many consumers discarded it again by
rendering bestThumbnail (usually a maxresdefault.jpg that 404s for
older videos) as a single URL with no fallback.
Extract the retry logic from VideoThumbnailView into FallbackLazyImage
and use it at every in-app site that can iterate: player thumbnails
(mini bar, expanded sheet loaders, autoplay previews, tvOS audio-mode
artwork - previously a silent black screen), video info card and tvOS
header, and the tvOS playlist cover.
Sites that fetch or send exactly one URL are rewritten to the
always-available hqdefault variant via Thumbnail.reliableURL (exposed
as Video.reliableThumbnailURL): Now Playing artwork, Top Shelf
snapshots, remote control state, the frozen transition thumbnail,
blurred info background, navigation covers, and playlist covers
derived from a video's first thumbnail in Invidious/Yattee Server
responses.
Also invert RecentPlaylist's upgrade helper, which rewrote covers *to*
maxresdefault, walk the quality chain when caching download thumbnails
for offline artwork instead of giving up after one 404, and expand the
remaining single-thumbnail Piped conversions into full chains.
Persistence models (local playlists, watch history, bookmarks,
downloads) store only the best advertised thumbnail URL - usually
maxresdefault.jpg, which doesn't exist for many older videos and 404s.
Live API results survive this because views fall back through the full
quality chain, but toVideo() rebuilt videos with that single dead URL,
leaving placeholder covers.
Reconstruct the quality fallback chain from the stored YouTube-style
URL at read time (Thumbnail.fallbackChain), and rewrite playlist list
covers to the always-available hqdefault variant
(Thumbnail.reliableURL), since those views render a single URL without
fallback. Also expand the fabricated maxres URL in PipedAPI into a
full chain.
Commit aed78c13f moved the session token from the Authorization header to a
?authToken= query parameter on /subscriptions, /subscribe, /unsubscribe,
/user/playlists, and /playlists/{id}. Piped's backend only accepts the
?authToken= form on /feed; every other authenticated route reads it from
Authorization (the Java handler names the variable "session", which is why
the rejected requests returned "session is a required parameter"). Restore
the header form for those five routes and leave feed alone.
Piped accepts the session token via either an Authorization header or an
authToken query parameter (the /feed endpoint already uses the latter form).
Switch all token-bearing Piped endpoints to the query-parameter form so the
Authorization header is free for HTTP Basic Auth from a fronting reverse
proxy. Affects subscriptions, subscribe, unsubscribe, userPlaylists, and
userPlaylist (including its nextpage pagination loop).
Malformed items in relatedStreams (e.g., missing title) no longer crash
the entire JSON decode. Reuses the existing PipedVideoItem (renamed from
PipedPlaylistItem) graceful-decoding wrapper for all relatedStreams arrays
in PipedStreamResponse, PipedChannelResponse, and PipedNextPageResponse.
Playlists only loaded the first page of videos. Add full pagination for
both Invidious and Piped playlist endpoints (public and authenticated).
Deduplicate Invidious results by playlist index to handle its overlapping
page windows. Also fix URL encoding in Invidious login to use strict
form-encoding charset.
