Highlights

  • Subtitle Delay / Offset (closes #4) — subtitledelay attribute, JS API, Z/X hotkeys (±100ms), OSD readout, and a subtitledelaychange event. Sign convention matches VLC/mpv. Auto-prefetch handles negative offsets, and a single offset works for text + image (PGS/DVB) cues without re-decoding.
  • Subtitle Customization Panel — subtitlesize, subtitlecolor, subtitlebg, subtitleedge attributes plus an in-player customize panel (size / color / background / edge) persisted via localStorage.
  • Subtitle Transcript Browser — full-cover panel with search, click-to-seek, active-cue highlight, italic/bold/entity rendering, delay-aware timestamps. Backed by a native movi_prefetch_subtitle_cues (uses AVDISCARD_ALL) so a 700 MB scan touches only subtitle packets.
  • Karaoke Captions for VTT — tag-only-token folding, offscreen min-width anchor, render-key cache to stop the 60fps innerHTML rewrite that prevented fade-in during playback.
  • Premuxed Quality Menu — multiple <source data-height="..."> children give a YouTube-style quality picker for plain MP4/MKV files (no HLS manifest needed). Adopt/release native <audio> across switches preserves the user-activation token so the next switch isn't blocked by autoplay policy.
  • Multi-Language Audio via <source kind="audio"> — two or more audio sources with srclang/label become parallel language tracks. Default pick: explicit default → first locale match → first track.
  • External Subtitles via <track> — standard <video>-style declarative markup. Reads srclang, label, and data-format (defaults to VTT, set srt for SRT sidecars).
  • Host Fullscreen Handoff — cancelable movi-fullscreen-request event + setHostFullscreen() so embedders (VS Code webviews, custom shells) can take over fullscreen with their own chrome while keeping the player's UI in sync.
  • VS Code Extension (Marketplace 0.2.5) — webview-hosted player as a CustomEditor. Single-click opens any MP4/MKV/HEVC/AV1/WebM/MOV/TS file VS Code can't natively play. True streaming via custom DataSource (memory cost drops from O(filesize) to ~chunk size — multi-GB and 8K HDR no longer hit the 4 GB Blob limit). OS wake lock during fullscreen.
  • Web App + Chrome Extension Explorer-Style Playlists — folder hierarchy tree, multi-select, live search, keyboard navigation, IndexedDB-cached thumbnails + metadata across sessions. Gradient circle brand mark.

Added

  • filerevoked CustomEvent — surfaces silently-revoked File handles (mobile background / memory pressure) instead of hanging forever.
  • MoviPlayer.hasAudibleSource() — unified audio-presence gate (muxed / split native <audio> / HLS).
  • 8K (4320p) and 16K (8640p) labels in Stats for Nerds — previously bucketed as 4K.

Changed

  • HLS volume controls now visible — hasAudibleSource() covers the HLS path too (volume button + ArrowUp/Down + OSD).
  • Audio decode stays running while muted — fixes the "atak atak" judder on unmute (audio clock no longer pivots to the demuxer's lookahead).
  • Bluetooth A2DP keepalive — pause now suspends the AudioContext but plays a near-silent loop so BT devices don't drop/re-pair on every pause.
  • DPR-scaled canvas backbuffer — capped at 2×, so 4K/8K downsampling stays sharp.
  • Encrypted source static import — EncryptedHttpSource hoisted to a top-level import (no async boundary on every encrypted load).
  • FFmpeg bumped to n8.1.1.
  • Subtitle default sizing — base size bumped, desktop-era 60px floor on bottom padding replaced with a height-proportional 8% (24px floor) so subtitles don't crowd into small embeds.
  • Menu animations — pop-in/out + fade between customize panel and track list. Bottom-controls dropdowns enforce one-at-a-time.
  • Hotkeys ignored while typing — no longer fire when an input/textarea inside the shadow DOM is focused.
  • Audio menu always shows language code alongside channel layout.
  • COOP/COEP hard-required — surfaces a "Security Headers Missing" diagnostic instead of a cryptic timeout. Mentions coi-serviceworker as a static-host workaround.

Fixed

  • Eliminated ~1s freeze when entering fullscreen.
  • Last frame shown as poster during WebGL context-loss recovery (no more black flash).
  • Stopped 2–3s jump-ahead on pause→resume; AudioContext stays alive on pause.
  • Mobile speaker tap opens the volume slider instead of muting.
  • Aspect-ratio change visible in paused state + poster overlay reflows.
  • Single-track streams exit pause buffering correctly.
  • HLS first-frame black; volume exposed in HLS; pause on blocked autoplay.
  • PGS subtitles stay on-canvas + transcript hidden on image subs.
  • Subtitle delay + transcript controls gated to file sources.
  • Fit animation preserved on HLS + quality badge repaints on ABR switch.
  • Robust backgrounding & WebGL context-loss recovery on mobile.
  • "Security Headers Missing" diagnostic instead of cryptic timeout.
