Animated and video live wallpaper for the DeepSeek Harness Web GUI — GIF, animated WebP/APNG and static PNG/JPEG images, plus MP4/WebM video backgrounds, with auto format detection, a dim slider, and UI chrome tone matching.
Install
# from npm (prebuilt)
dsh plugin --profile web add dsh-thirteen-bg
# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)
dsh plugin --profile web add github:feng78-boop/dsh-thirteen-bg
Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).
README
This plugin publishes its README in Chinese only.
DeepSeek Harness Web GUI 动态背景插件（live wallpaper），by 十三 / thirteen。
支持 GIF / 动图 WebP / APNG / 静态 PNG / JPG 图片，以及 MP4 / WebM / MOV 视频背景——
格式自动识别：上传或填 URL 时按扩展名/MIME 判断，视频走 <video> 层
（静音循环、硬件加速、切后台自动暂停），图片走 CSS background-image。
纯客户端插件，设置存于浏览器 localStorage，上传文件存 IndexedDB（不限大小）。
Demo
15 秒实拍：DeepSeek Harness Web 界面 + 动态背景效果。
安装
dsh plugin --profile web add <本目录的绝对路径>
# 例如（本地路径安装）
dsh plugin --profile web add C:\Users\fhd19\deepseek_harness\dsh-thirteen-bg
# 发布到 npm 后
dsh plugin --profile web add dsh-thirteen-bg
装完后重启 dsh web 生效（或直接刷新浏览器——客户端代码改动刷新即生效）。重启后：
- 浏览器硬刷新（Ctrl+F5）
- 「设置」→ 通用 → 找到 动态背景 卡片
- 上传本地动图/视频（不限大小，存 IndexedDB），或粘贴 http(s) 媒体 URL，调节压暗程度
⚠️ 本地文件路径（如
C:\...或file:///...）不能作为 URL 使用——浏览器会拦截。 本地媒体请用「上传」按钮；远程媒体才填 URL。
媒体标准
| 类型 | 建议 |
|---|---|
| 图片（动图） | GIF / 动图 WebP（推荐）/ APNG；长边 ≤ 1920px；8–20 秒无缝循环 |
| 图片（静态） | PNG / JPG 均可作高清静态壁纸；长边 ≤ 1920px |
| 视频 | **MP4（H.264）**或 WebM（VP9）；1080p 足够；10–60 秒（loop 自动循环，无需首尾无缝） |
| 通用 | 深色/低饱和为主（背景后有文字，插件自带「压暗」滑块）；体积建议 ≤ 几十 MB 保证流畅 |
压缩工具
- 动图：ffmpeg
ffmpeg -i in.mp4 -vf "scale=1920:-1,fps=15,format=rgba" -loop 0 out.webp；Squoosh - 视频：ffmpeg
ffmpeg -i in.mov -vf "scale=1920:-1" -c:v libx264 -crf 23 -an out.mp4
与其它皮肤插件共存
背景层是真实元素（position:fixed; z-index:-1 的 div / video），挂在
<html> 下，不占用 html::before/::after 伪元素，因此与
dsh-client-ui-skins、dsh-dream-skin 等用伪元素做背景的皮肤零冲突：
本插件层按 DOM 顺序绘制在皮肤层之上，动态背景始终可见；关闭本插件即恢复静态皮肤。
