* feat: support batch video upscaling with folder upload and directory save
- Add multi-file selection and entire folder upload (webkitdirectory)
- Support drag & drop of both files and folders via FileSystemEntry API
- Add save directory picker using File System Access API (showDirectoryPicker)
- Process videos sequentially with per-file progress and status tracking
- Add right-side result list with click-to-compare functionality
- Add per-video duration and total batch duration display
- Add retry button for failed items with error detail display
- Remove auto-play on comparison viewer load
- Fix worker error handling: handle "error" command to reject stale promises
- Fix event listener accumulation in video comparison (AbortController)
- Fix XSS risk by escaping HTML in all innerHTML injections
- Fix URL revocation timing in download to prevent large file truncation
- Extract writeToSaveDirectory and truncateName helpers to reduce duplication
- Add Usage Guide panel explaining single/multiple/folder upload options
Files changed:
docs/upscaler/index.html (+1110/-181)
docs/upscaler/upscaler.js (+110)
* fix: prevent auto-play and resource consumption during upscaling
- Set preload="metadata" on preview and comparison video elements
- Explicitly pause preview video after setting src in showVideoPreview
- Remove preview video seek sync from batch processing progress callbacks
(was causing continuous decode during upscaling, wasting GPU resources)
- Remove preview video seek sync from retry progress callback
- All videos now require manual play; no background resource usage
* fix: improve upscaled video quality with higher bitrate and codec support
- Raise base bitrate from 2.5 Mbps (25e5) to 8 Mbps (8e6) for standard and
firefox processors, preventing quality loss when source videos have high
bitrates (e.g. 720p @ 16.7 Mbps was producing 1440p @ 10 Mbps, smaller
than the original file)
- Double the bitrate for mediabunny processor (X.n1 * 2) to account for the
4x pixel increase from 2x upscaling
- Add H.264 Level 5.1 (avc1.640033) and Level 5.2 (avc1.640034) codecs to
the fallback lists, since Level 4.0 (avc1.640028, ~24.6 Mbps) cannot
support the higher bitrates for 1440p+ outputs
- Add latencyMode: "quality" to VideoEncoder configs for both standard and
firefox processors, prioritizing encoding quality over latency (suitable
for offline processing)
* feat: add video data comparison panel for original vs upscaled metrics
- Add a comparison data table below the file info bar showing 6 metrics:
Resolution, File Size, Duration, Est. Bitrate, Pixels, Process Time
- Display per-metric change percentage with color-coded indicators:
green (↑) for improvements, red (↓) for regressions, gray for neutral
- Estimated bitrate calculated from file size × 8 / video duration
- Table renders after both original and upscaled video metadata loads
- Auto-hide panel on reset
* fix: make video data comparison panel full-width and responsive
- Move comparison data table from inside the left column to the full-width
area below the left/right layout, so it is no longer constrained by the
comparison viewer column width
- Remove table-fixed colgroup and overflow-x-auto that caused horizontal
scrolling on smaller screens
- Table now uses w-full auto-layout, displaying all 4 columns (Metric,
Original, Upscaled, Change) without requiring horizontal scrolling

`art.play()` is an async wrapper around the native `video.play()` promise, which
rejects when a pending play request is interrupted (`pause()`, `load()`, a new
`src`, or the element being removed) and when autoplay is blocked.
Every internal caller fires it from an event handler and cannot await it, so the
rejection escapes as a global `unhandledrejection`. Error trackers report it as
an uncaught crash even though the player recovers on its own — for example
destroying the player right after mount, which is routine when the video sits in
a modal the user can close quickly.
Add a `silencePromise` util (the same approach video.js uses) and apply it to the
non-awaited internal call sites: mask, play control, mini player, loop restart,
autoPlayback jump, hotkey and click toggles.
`switchMix` is fixed too, for a second symptom: `await art.play()` inside the
async `video:canplay` handler both leaked the rejection and left the `switchUrl`
promise pending forever, since the throw never reached the enclosing executor's
`reject`. It now settles.
The public API is unchanged: `art.play()` and `art.toggle()` still return the
original promise, so applications that call them keep their own rejection to
handle. Only the internal, non-awaited copy is silenced.
The notice.show getter was declared as boolean while the setter accepts string, Error or false. TypeScript uses the getter return type when checking property assignment, causing TS2322 when assigning a string to notice.show.
Root causes fixed:
1. Remove starvation check that suspends AudioContext — it freezes the
video clock and causes playback to stall permanently
2. Add backpressure (1s BUFFER_AHEAD) to prevent audio pump from decoding
unbounded buffers, starving the video decoder
3. Add setTimeout(0) yield between batches so video rAF callbacks can run
4. Batch audio buffer reads (16 per iteration) to reduce IPC overhead
5. Fix latestScheduledEndTime time-domain: use media-time (same domain as
currentTime) instead of AudioContext-time, so backpressure check works
correctly after seeking
Without these fixes, playing a large file (9+ GB) with audio causes:
- Audio pump decodes hundreds of buffers in 1 second (195s of audio decoded
in 1s wall clock)
- Main thread blocked by 177 IPC calls/sec from audio iterator
- Video frames never render (rAF starved)
- After seek: backpressure never triggers due to time-domain mismatch,
causing persistent stutter and eventual silence
feat: add danmuku plugin and i18n setup documentation
- Introduced a new danmuku plugin with multiple run code options in the documentation.
- Added language settings documentation for i18n, including default languages, import instructions, and examples for adding and modifying languages.
- Implemented input handling for media sources in the artplayer-proxy-mediabunny package, supporting various formats including HLS.
- Created m3u8 control functionalities for managing audio and video quality settings in the player.
