Feature/lyrics updates - #324
Conversation
Fetches first 20 tracks from YT music when list=URL is parsed and plays,remaining tracks are fetched in the background and added in batches of 20. Added the --expand-playlist/--no-expand-playlist CLI flags and the expand_playlist key in the configs. This is switched on by default
📝 WalkthroughWalkthroughThe change synchronizes gapless pipeline swaps under the speaker lock, defers retired-pipeline cleanup, adds a race regression test, and expands synced lyrics support for finite-duration yt-dlp tracks. ChangesGapless playback synchronization
Lyrics synchronization rules
Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🟠 High · up to During gapless playback, a race can leave track metadata and decoder state out of sync, potentially causing incorrect transitions or playback failure. The synchronization issue should be fixed before this PR is merged. Possibly related PRs

describing lyrics scrolling and highlighting in time with playback.
In `@player/gapless_test.go`:
- Around line 70-99: Make the gapless swap regression test deterministic by
blocking the onSwap callback with a channel, running gapless.Stream in a
goroutine, and asserting Stream remains blocked until the callback is released.
Update the test setup around onSwap and Stream so the assertion occurs before
the player state is superseded, then release the callback and wait for
completion; avoid relying on scheduler timing or merely waiting on swapDone.
In `@player/player.go`:
- Around line 119-123: Update preloadPipeline and other source-and-pipeline
replacement paths to retain p.mu while the speaker lock is held, committing the
gapless stream update and p.nextPipeline assignment atomically before releasing
either lock. Preserve the lock ordering used by gaplessSwap so transitions
cannot observe stale pipeline metadata or retire the active decoder.

Commit the stream and pipeline state in one speaker-locked transaction.
At Line 121, gaplessSwap promotes p.nextPipeline. In preloadPipeline, the code releases the speaker lock after p.gapless.SetNext(tp.stream) but before it stores tp in p.nextPipeline at Line 268.
A gapless transition in this window promotes stale metadata. The later preload then stores the active pipeline as p.nextPipeline. The next preload can close that active decoder as its retired next pipeline.
Hold p.mu while the speaker lock is retained. Update both the gapless stream and p.nextPipeline before either lock is released. Apply the same ordering to other source-and-pipeline replacement paths.

Summary
Support for synced lyrics on YouTube Music and other
yt-dlptracks.Until now, synced (auto-scrolling, timestamped) lyrics only worked for local files and Navidrome. YouTube/
yt-dlptracks were always forced into manual scroll mode ; even though timestamped LRC was already being fetched from LRCLIB/NetEase. The exclusion relied on a stale comment claimingyt-dlpstreams report position 0; in reality, position has been tracked from decoded PCM frames since from March.This PR lets
yt-dlptracks with a known duration use synced lyrics: the active line auto-scrolls and highlights in time with playback, including after seeking. Streams without a finite duration (e.xx. YouTube Live) stay in scroll mode, since their position isn't song-relative.This was confirmed to be working using
