Direct Play on Apple TV develops recurring micro-stutter that worsens
the longer playback runs and clears temporarily on pause/play
(issue #1776). Since 2.4 the avfoundation VO has presented frames
against a media-time CMTimebase anchored and rate-servoed to follow
mpv's audio-slaved schedule; clock skew between the two domains can
only be retired by rate slewing or a re-anchor snap that retimes every
queued frame at once. The media timebase exists for PiP, which tvOS
does not have.
Bump MPVKit to 1.0.22 and opt tvOS into its new
avfoundation-presentation=host mode: samples carry mpv's scheduled
display time against a free-running host-clock timebase, so drift is
absorbed per frame inside mpv and no timing state accumulates in the
VO. The queue lead returns to 128ms; 500ms only dampened media-mode
snaps and quadrupled their blast radius. 1.0.22 also paces the
compressed-passthrough feed off the most-advanced playhead reading,
fixing the periodic audio dropouts passthrough users reported on 2.14.
Audio-only mpv core on every platform (dedicated
com.plezy/mpv_audio_player channels): parameterized android/windows/
linux mpv plugins and a new apple MpvAudioPlayerCore, all skipping
video/window paths (vid=no, audio-display=no, gapless-audio=weak).
MusicPlaybackService drives an in-memory queue with shuffle/repeat,
file-loaded-event gapless arming (property edges coalesce and the
android bridge drops them), per-track progress reporting, OS media
controls, audio focus, sleep timer, and error auto-skip.
PlaybackCoordinator enforces one live native player: starting video
disposes the audio core first.
