When the display/system sleeps with a video paused, the window server
stops completing CAMetalLayer presents and mpv's MoltenVK swapchain wedges,
pinning one core at 100% until the app exits. occlusionState does not
reliably change on display sleep, so observe NSWorkspace screensDidSleep/
Wake to hide the metal layer (and drop the playback activity) while dark,
restoring on wake with a forced redraw when paused to avoid a stale frame.
Pairs with MPVKit v1.0.10, which gates libmpv presentation on the layer's
hidden state (check_visible) so presents actually stop while hidden.
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.
Routes all single-layer DV profile 8 (incl. compat 0) through the Apple
DV decode path, so VideoToolbox decodes it in hardware as true Dolby
Vision instead of failing over to software HDR10. Refs #1262.
- Remove vulkan-swap-mode mailbox (continuous GPU rendering even when paused)
- End playback activity assertion on pause, restore on play
- Fix PerformanceStatsService persistent frame callback leak
