dsh-cinematic-wallpaper

English | 中文

A DeepSeek Harness (DSH) web plugin. Every time the page opens, a character awakens in a 7-second cinematic intro; then the scene settles behind the DSH UI as an animated session wallpaper, and the UI's text colours adapt to whatever is behind them.

What it does

• Intro (7 s).
• The first 2.7 s play the film's line-art beat (light strands, wireframe, face scan). It comes from a cut-out clip whose baked-in HUD has been removed frame by frame.
• From there the animation is code-driven: the eye opens, the iris flares green, the camera pushes in.
• The HUD (logo, wordmark, status list, terminal, corner marks) is drawn in code.
• Click, or press any key (IME input included), to skip. Keys pressed during the intro never reach the composer.
• Handoff (0.9 s). The left HUD fades out and the DSH UI fades in.
• Session wallpaper.
• The character stays behind the UI, with the right-hand corner marks.
• An AI-generated idle loop plays over it: the hair sways at half speed, played forward then back, about 24 s per cycle.
• The canvas redraws at most 30 fps while the loop plays, and 10 fps without it.
• Translucent UI. There is no fog over the wallpaper in either theme. DSH's surfaces follow its theme as translucent layers, the composer especially so: 28 % opaque in the light theme, 30 % in the dark one.
• Adaptive text colour.
• Each visible piece of text (and each icon and placeholder) takes the light or dark text colour that contrasts best with what is really behind it: the wallpaper under it, with the UI's translucent surfaces composited on top. It also gets a faint halo.
• Text on opaque surfaces keeps DSH's colours. Coloured text keeps its colour and only gains the halo.
• Colours are recomputed on resize, theme change, UI changes and scrolling, and once a second while the loop plays.
• Fallbacks.
• With "reduce motion" on, the intro is skipped and the wallpaper is a still.
• A hidden tab pauses everything.
• If the assets have not loaded within 4 s, the layer removes itself and DSH works as usual.
• A missing clip only drops the line-art beat. A missing loop leaves a still wallpaper.

Install

Requires DSH >= 0.1.5-rc.1 and its web profile.

From the release package (prebuilt, includes the two videos):

dsh plugin --profile web add https://github.com/zus12873/dsh-cinematic-wallpaper/releases/latest/download/dsh-cinematic-wallpaper.tgz
dsh web

Restart dsh web after installing or updating. Check that the host half is mounted:

curl http://127.0.0.1:3080/dsh-cinematic-wallpaper/health

Uninstall:

dsh plugin --profile web remove dsh-cinematic-wallpaper

This plugin covers the same ground as boot-animation and wallpaper plugins, and with one of those installed the two stack on top of each other. Remove them while using this one.

Build from source

git clone https://github.com/zus12873/dsh-cinematic-wallpaper.git
cd dsh-cinematic-wallpaper
npm ci
npm run build
dsh plugin --profile web add link:"$PWD"

The two videos (assets/clip.mp4, assets/loop.mp4) are not in Git. Without them the plugin still runs, but without the line-art beat and the idle loop. To get them, take them from the release package:

curl -L -o /tmp/dcw.tgz https://github.com/zus12873/dsh-cinematic-wallpaper/releases/latest/download/dsh-cinematic-wallpaper.tgz
tar -xzf /tmp/dcw.tgz -C assets --strip-components=2 package/assets/clip.mp4 package/assets/loop.mp4

Change the HUD layout

Every HUD element is a row of the LAYOUT table in src/client/layout.ts:

• anchor: the window corner it is pinned to, tl / tr / bl / br;
• x / y: design coordinates on a 1920×1080 frame;
• scale (optional): multiplies the group's scale;
• intro / hold: whether it shows during the intro / on the wallpaper;
• holdAt (optional): a separate { anchor, x, y, scale } for the wallpaper; the handoff moves it there smoothly.

Run npm run build and restart dsh web after a change.

Development

npm run dev   # http://127.0.0.1:5181

• /?mode=play&t=3.0: scrub or play the intro.
• /?mode=compare&t=3.0: the code render and the source film side by side.
• /?mode=mock: the real runtime over a stand-in DSH shell (handoff, theme tokens, keys).

play and compare overlay the source film from .cache/reference.mp4, which authoring.measure --proxy makes from it.

Regenerating the assets

The pipeline in authoring/ is Python, run through uv. It does two things:

• turns the source film into the plate, the closed-eye patch, the manifest and the line-art clip;
• turns an AI-generated idle clip into the loop.

The hand-measured values in authoring/regions.py belong to that one film, and neither the film nor the idle clip is distributed, so the pipeline is only useful with the same sources:

uv run --group authoring python -m authoring.build_assets --video <film.mp4> --out assets --debug .cache/debug
uv run --group authoring python -m authoring.build_loop --source <idle-clip.mp4> --out assets
uv run --group authoring python -m authoring.fonts --out assets/fonts

build_loop does the following:

1. matches the idle clip's first frame to the still to find the area it covers;
2. grades the clip's tones back to the still's;
3. plays it forward and back at half speed, with motion-compensated in-betweens;
4. records in the manifest how wide its left fade can be without crossing the hair.

Tests

npm test && npm run typecheck
INTRO_FILM=<film.mp4> IDLE_CLIP=<idle-clip.mp4> uv run --group authoring pytest authoring/tests -q

Tests that need the film or the idle clip are skipped when those variables are not set.
