Inline banners and per-row status text reported action results all over
the app; they are replaced by a small toast stack (bottom-right, Level 3
floating well styling) that only speaks for actions: successes fade,
errors stay until dismissed, and form-field validation stays inline.
Destructive actions no longer use bespoke inline confirm steps (the
library detail's Confirm delete button) or fire immediately (duplicate
copies/items, delete page selections, temp cleanup, upload discard, job
cancellation): they all go through one promise-based confirm dialog
(confirmAction) with a danger variant, Escape/backdrop to cancel.
- Animated WebP (J-82) was being flattened to its first frame: browsers
have no animated WebP encoder, so the modal now sniffs the file header
(4 KB range request), explains the limitation and disables Process
instead of overwriting the file with a single frame.
- APNGs saved as .png took the still-image path and lost their frames;
the header sniff looks for the acTL chunk, routes them to the animation
pipeline (all frames + delays) and switches the UI to the animation
options. The worker double-checks the header too, so no path can
flatten an APNG.
- New dependency-free imageformat module, verified against real files
(J-82 animated, static WebP/PNG, and a generated APNG named .png).
The optimizer now shows which browser is running (e.g. "Firefox 141")
next to the encoder probe results, explains the common Firefox case
("Firefox does not implement H.264/HEVC encoding"), and offers a
one-click switch to the container that has working encoders.
Your machine's H.264/HEVC encoders report support and then emit no video
samples at all, which no configure-time check can see. The optimizer now
test-encodes three frames per codec (cached for 30 days), shows the result
as diagnostics in the modal (AVC x / VP9 (hardware) / ...), feeds the
working codecs to the worker so Auto tries them first, and tells you to
switch to WebM when a container has no usable encoder.
Video quality is now a 10-100 slider with a predicted bitrate and size
for this clip (mirroring Mediabunny's mapping), which makes the trade-off
visible instead of guessing from presets.
The hand-rolled chunk assembly was verified correct in Node but still
produced a broken MP4 in the browser, so stop relying on it: the muxer now
streams into an Origin Private File System file (random access is exactly
what MP4 needs), the worker returns the OPFS File directly, and the entry
is deleted after a successful apply (stale ones are purged hourly). The
chunk collector remains only as a fallback for browsers without OPFS.
The result is validated before it reaches the UI: MP4s must contain a
moov box and WebM files must start with the EBML magic, so a broken muxer
output surfaces as an error instead of a 0x0 preview.
- The streaming assembler applied chunks sorted by position, so header
patches written last could be overwritten by earlier data. Chunks now
apply in arrival order (newest write wins per byte range) and are only
laid out by position afterwards.
- The Optimize modal now reads the media metadata itself: both previews
show resolution and duration, and the processed video is flagged in red
when it comes out shorter than the original (a truncated encode is no
longer something you have to guess by file size).
Backend:
- POST /api/files/J-x/optimize/ applies a browser-processed file: replaces
every copy (renaming when the extension changes), recomputes MD5, size
and perceptual hashes, seeds guest visibility; 400 when identical,
409 when the result matches another item, owner/staff only.
Frontend (no server-side processing by design):
- optimize.worker.ts + pipelines: Mediabunny/WebCodecs for video with a
prefer-hardware hint and per-browser codec detection; MozJPEG/OxiPNG/
libwebp (jSquash) for images; gifuct-js+gifenc and UPNG for GIF/APNG.
- OptimizeModal: per-file-type options, original vs processed previews
with sizes/savings, progress bar with ETA, then Apply (overwrite).
- Optimize button on the library detail for the uploader/staff.
