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

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:

1. 浏览器硬刷新(Ctrl+F5) 2. 「设置」→ 通用 → 找到 动态背景 卡片 3. 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:\...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)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.webpSquoosh
  • 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-skinsdsh-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。
