Two requested features in one ship.
Autoplay:
* Settings → Autoplay section. Three modes: Off, Same channel,
YouTube related. Default Same channel — per Cobb 2026-05-26,
"plays next account's video".
* Skip-already-watched toggle, default on. Autoplay picks the
first un-watched candidate (filters History.watches by videoId).
* When STATE_ENDED fires and the queue has no next item,
PlaybackService's autoplay handler picks a candidate per mode,
resolves it via strawcore, and enqueues — which auto-starts
because the queue is empty (enqueueLast routes through
setPlayingFrom in that case).
* SameChannel calls strawcore.channelInfo(uploaderUrl).take(1).
Plumbed NowPlayingItem.uploaderUrl + setPlayingFrom/enqueueLast
sig to carry it forward so the autoplay handler has what it
needs without re-resolving.
* YtRelated re-resolves the current streamInfo and picks
info.related[0]. strawcore returns empty for related today, so
YtRelated falls open to no-op until that extractor work lands —
documented in the AutoplayMode enum help text.
SponsorBlock for queued items:
* The vc=47 known-limitation. Now: when onMediaItemTransition
surfaces a queued item with empty SB segments, fire a
background fetch of SB for that video, then NowPlaying.claim()
again with the freshened segments. The skip-loop (reactive on
NowPlaying.current.segments) picks them up.
* Fetch lives in StrawApp.globalScope — outlives the controller
transition + sheet UI.
Refactor:
* StrawMediaController extensions retyped from MediaController →
Player so PlaybackService can call them on the ExoPlayer
directly. MediaController IS a Player so all existing UI call
sites continue to work.
* Shared extractYtVideoId util in feature/detail/StreamResolution.kt.
The duplicate VIDEO_ID_RE in StrawHome.kt will fold into it next
time that file is touched.
