DSH Video Player / DSH 刷视频

DSH web GUI client plugin: TikTok-style vertical video feed in a floating window.
DSH web GUI 客户端插件：浮动窗口里的抖音式竖屏刷视频（窗口随视频自适应 + SMB NAS）。

---

English

A client plugin for the DSH web GUI: adds a "video" button at the bottom of the sidebar. Clicking it opens a floating window where you point at a folder (local or SMB-mounted), press "play this folder", and swipe through its videos TikTok-style — arrow keys, mouse wheel, or drag.

Features

• Directory browsing: enter an absolute path (defaults to the current session's working directory) — lists subdirectories plus all videos inside (recursive, depth 8 / 2000-file cap); "▶ Play this folder" starts the feed;
• TikTok-style feed: full-screen scroll-snap + depth animation (current video scaled up, neighbors shrunk and dimmed); a finished video auto-advances to the next, and an "all done" card appears at the end;
• Switching: ↑/↓ keys, mouse wheel, or drag on the video (1:1 tracking; releases dock to the nearest video; paused while dragging, resumes on release);
• Seeking: ←/→ ±5 seconds with a ⏩/⏪ flash; the bottom progress bar is click-to-seek;
• Playback: Space or single-click toggles pause; M mutes; Esc or ✕ closes; auto-play blocked by the browser degrades to muted with an "unmute" hint;
• Aspect-ratio auto-fit: the window fits the current video's ratio at ¼ of the native size (240 px floor, viewport-clamped); switching between portrait/landscape re-fits live; manual resizing turns auto-fit off;
• Auto-hide UI: mouse leaving the window fades out the title bar, resize handle and top/bottom info bars — a pure video window (restored on mouse enter; the cursor hides too);
• Resizable via the bottom-right ⋱ handle (min 240×240); title bar is draggable — position + size + auto-fit state are remembered in sessionStorage; double-click the title bar to reset position and re-enable auto-fit;
• Fullscreen: F or the ⛶ button; Esc exits fullscreen first, second Esc (or ✕) closes the window;
• SMB NAS: with the share mounted on the dsh host, accept the mount-point path, smb://host/share/sub, or \\host\share\sub — the host resolves it to the local mount by parsing mount output (Chinese share names in raw or percent-encoded form all match);
• Range streaming via /video-player/stream (HTTP 206) — seeking sends ranged requests, never a full-file download;
• Online videos (yt-dlp): paste a yt-dlp-supported video / playlist / uploader URL into the same address bar (bilibili, YouTube, …) — the list is fetched via --flat-playlist (in-memory, 30 min); single-file progressive streams are proxied by the host (browser UA + Referer + Cookie, Range passed through); DASH/HLS segment streams (all bilibili) are auto-downloaded and merged to a local mp4 (≤1080p, needs ffmpeg) and then served as a local Range stream — each video downloads once, replays are instant;
• Generic page fallback (no per-site code): when yt-dlp cannot extract a list at all, the host fetches the page itself and scans the HTML for direct media links (tag attributes, inline JSON, JSON-LD — escaped or not), normalizes vendor URL quirks (trailing slashes, prefers signed/?token= variants over bare duplicates) and lists whatever it finds for you to pick — covers "plain" sites with no yt-dlp extractor;
• bilibili 1080p: with a logged-in cookies.txt selected, bilibili single videos prefer a one-time 1080p DASH download into the cache (instant replay after); anonymous (or cookie-less) falls back to the instant 480p progressive relay;
• Login state (cookies.txt): the 🍪 row in the browse card selects / uploads / deletes a browser-exported cookies.txt (stored under ~/.dsh/video-player/cookies/); only non-expired, domain-matching cookies are forwarded (a whole-browser export stays under CDN header limits); needed for high-quality / members-only / login-gated content;
• yt-dlp & ffmpeg discovery (no machine-specific paths in the repo): local config ~/.dsh/video-player/config.json → {"ytdlp": "<path>", "ffmpeg": "<path-or-dir>", "extractorArgs": ["generic:impersonate", "youtube:player_client=mweb,android"]} > DVP_YTDLP env > PATH (yt-dlp / yt-dlp.exe) > python -m yt_dlp; the first candidate that answers --version wins (cached); each extractorArgs entry is passed as its own --extractor-args flag (re-read on every call — no restart needed);
• Chat push (agent): the dsh agent can push a video into the player — POST /video-player/queue {"url","title"} (in-memory, 10 items max, 30 min TTL); an open player window polls every 2 s and auto-plays the first pending item (📥 toast); while the window is closed the items wait and play as soon as it opens; the agent can search first with yt-dlp (bilisearch5:<topic> / ytssearch5:<topic>) and push the pick;
• Cache cleanup: the 🧹 button in the cookie row shows the DASH-merge cache size and clears it with one confirm (GET/DELETE /video-player/cache; files locked by active playback are skipped and reported).
• Memory-friendly: only the current video ± 1 neighbor preload sources; far-away videos release their buffers;
• Supported formats: mp4 / m4v / webm / ogv / ogg / mov / mkv / avi / flv / ts / mpg / mpeg / 3gp / wmv (decoding depends on Chromium; a codec it can't handle shows a "can't play" card and auto-skips).

Security boundaries

• The host half registers only /video-player-prefixed routes; list/stream are GET/HEAD only — write routes: /video-player/cookies (POST upload / DELETE, name-validated [A-Za-z0-9][A-Za-z0-9._-]{0,63}, 5 MB cap, stored under ~/.dsh/video-player/cookies/), /video-player/cache (DELETE, only the plugin's own cache dir), /video-player/queue (POST, in-memory push queue — no file or network side effects);
• File access is limited to the video extension whitelist above, regular files only; Range offsets are validated against file size;
• Directory listings are capped (2000 files / depth 8); unreadable entries are silently skipped;
• Accessible paths = whatever the local shell can read (the GUI listens on 127.0.0.1 by default);
• SMB input is resolved by parsing mount output — credentials never touch the plugin (mounting is system-level: Finder ⌘K / mount_smbfs); a dropped mount yields a "please remount" hint instead of a raw EIO.

Files

File	Role
package.json	Package manifest + dsh.bundle (install layer) + dsh.client (browser-half discovery)
cordis.patch.yml	Bundle patch layer activated by dsh plugin add; registers the video-player Loader row
index.js	Host half (node): /video-player/list (local + yt-dlp remote lists) + /video-player/stream (local Range / online proxy / DASH cache download) + /video-player/cookies (GET/POST/DELETE) + /video-player/cache (GET/DELETE) + /video-player/queue (GET/POST), incl. SMB path resolution
client.js	Browser half (classic script bundle, no build step)

Install

Install the official runtime with Node.js:

npx @deepseek-ai/dsh web

Install this plugin into a profile (the ecosystem convention):

dsh plugin --profile web add "github:anitman/dsh-plugin-video-player#main"

dsh plugin forwards package operations to pnpm, so npm, Git/GitHub, local path, file: and link: package specs are all supported — e.g. from a local clone:

dsh plugin --profile web add .

Only packages declaring dsh.bundle.patch become active profile layers; this package declares it, so dsh plugin add completes the link and layer activation in one step. Pure JS, no build scripts — a git install needs no allowBuilds approval.

Restart dsh --profile web after installing or updating a bundle: the "▶ 刷视频" button then appears at the bottom of the sidebar (above the settings button); manage it under Settings → Plugins.

Uninstall

dsh plugin --profile web remove dsh-plugin-video-player

Removes the dependency and the patch layer together; restart dsh to take effect.

Manual fallback (without the dsh CLI)

1. Create a symlink dsh-plugin-video-player in ~/.dsh/profiles/web/node_modules/ pointing at this directory (or copy the directory if symlinks fail);
2. Add to dependencies in ~/.dsh/profiles/web/package.json: "dsh-plugin-video-player": "file:<absolute path to this repo>";
3. Append to the top-level array of ~/.dsh/profiles/web/cordis.patch.yml:

   - insert:
       - id: video-player
         name: "dsh-plugin-video-player"
   

4. Restart the dsh process (new Loader rows are only scanned at startup; sessions restore automatically).

Updating

• Only client.js changed: no restart needed, client-HMR hot-reloads the plugin (requires the host-side watch chain to be active; otherwise refresh the page);
• index.js (host half) changed: dsh restart required;
• Local clone installed via add .: git pull, then restart dsh;
• Installed via github:: re-run the install command with a new #ref to upgrade;
• If node_modules holds a copy instead of a symlink: re-copy after changes (or switch back to a symlink).

简体中文

DSH web GUI 客户端插件：侧栏底部多一个「▶ 刷视频」按钮，点开是一个浮动窗口，指向一个文件夹（本地或 SMB 挂载的 NAS）后按「播放此文件夹」，即可抖音式连续刷视频。

功能

• 目录浏览：输入绝对路径（默认填入当前会话工作目录），列出子目录 + 该目录（含子目录，深度 8 层、最多 2000 个）内的全部视频，点「▶ 播放此文件夹」开始刷；
• 抖音式刷视频：整屏 scroll-snap 吸附 + 景深动画（当前视频放大、上下略缩小变暗）；一个播完自动切下一个（顶栏 🔁 循环 按钮可切换为循环重播当前视频，选择持久化），全部刷完出现「已刷完」卡片；
• 切换：↑/↓ 键、鼠标滚轮、或按住视频上下拖拽（1:1 跟手，松手自动停靠到最近的视频；拖拽中自动暂停、松手恢复）；
• 快进快退：←/→ 键 ±5 秒（带 ⏩/⏪ 大提示），底部进度条可点击跳转；
• 播放控制：空格 或单击视频暂停/播放；M 静音；Esc 或 ✕ 关闭；自动播放被浏览器拦截时降级为静音并显示「解除静音」提示；
• 窗口随视频宽高比自适应：窗口按当前视频比例适配，默认大小为原始尺寸的 1/4（过小等比放大到 240px 下限，过大缩进视口内）；竖屏↔横屏切换实时变形；手动调整尺寸仅作用于当前视频，切换到新视频时窗口自动恢复按宽高比适配；
• 鼠标离开自动隐藏：鼠标移出窗口后，标题栏、右下角缩放手柄、顶/底信息栏淡出——窗口变成纯视频画面（移入即恢复，鼠标指针也隐藏）；
• 右下角 ⋱ 手柄可调窗口大小（最小 240×240）；标题栏可拖动，位置 + 尺寸 + 自适应状态记在 sessionStorage；双击标题栏同时复位位置并恢复自动适配；
• 全屏：F 或 ⛶ 按钮；Esc 先退出全屏，第二次 Esc（或 ✕）关窗；
• SMB NAS：共享挂载在运行 dsh 的机器上后，可直接输入挂载点路径、smb://主机/共享名/子目录 或 \\主机\共享名\子目录 —— 宿主解析 mount 输出自动换算成本地挂载路径（中文共享名的原始/percent-encoded 形式都能匹配）；未挂载时给出具体挂载命令；
• /video-player/stream Range 流式播放（HTTP 206）：快进/拖动进度条只发分段请求，不整段下载；
• 在线视频（yt-dlp）：地址栏直接粘贴 yt-dlp 支持的视频/UP主/播放列表网址（bilibili、YouTube 等）——列表内存缓存 30 分钟；单文件渐进流由宿主代理转发（补浏览器 UA/Referer/Cookie，Range 透传）；DASH/HLS 分段流（bilibili 全 DASH）自动下载合并为本地 mp4（≤1080p，需 ffmpeg）再本地 Range 播放，同一视频只下一次、之后秒开；
• 通用页面兜底（零站点特判）：yt-dlp 完全提不出列表时，宿主自己抓页面 HTML，用通用规则（标签属性 / 内联 JSON / JSON-LD，含转义斜杠形式）扫出媒体直链，归一化站方怪写法（尾斜杠、同路径优先保留带 ?token= 签名的变体）后全部列出让用户挑——覆盖没有 yt-dlp 提取器的"朴素"站点；
• bilibili 1080p：选中已登录的 cookies.txt 时，bilibili 单视频优先一次性下载 1080p DASH 进缓存（之后秒播）；无登录态则回落到即时的 480p 渐进流代理；
• 登录态（cookies.txt）：浏览卡片里的 🍪 一行可选择/上传/删除浏览器导出的 cookies.txt（存于 ~/.dsh/video-player/cookies/）；只转发未过期且域匹配的条目（整浏览器导出也不会超 CDN 头限制）；高清/会员/需登录内容必备；
• yt-dlp 与 ffmpeg 定位（仓库不含任何机器特定路径）：本机配置 ~/.dsh/video-player/config.json → {"ytdlp": "<路径>", "ffmpeg": "<路径或目录>", "extractorArgs": ["generic:impersonate", "youtube:player_client=mweb,android"]} > 环境变量 DVP_YTDLP > PATH（yt-dlp/yt-dlp.exe）> python -m yt_dlp；第一个能通过 --version 的候选胜出并缓存；extractorArgs 每条作为独立 --extractor-args 传入，每次调用重读配置（改完即生效，不用重启）；
• 对话推送（agent）：dsh agent 可以把视频推进播放器 —— POST /video-player/queue {"url","title"}（纯内存，最多 10 条，30 分钟过期）；打开中的播放窗口每 2 秒轮询一次，自动播放第一条待播视频（📥 提示）；窗口没开时视频先排队，开窗即播；agent 可先用 yt-dlp 搜索（bilisearch5:<话题> / ytssearch5:<话题>）挑一个再推；
• 缓存清理：🍪 一行的 🧹 按钮显示 DASH 合并缓存的大小，点一下确认即清空（GET/DELETE /video-player/cache；正在播放占用的文件跳过并报告）。
• 内存友好：只预载当前视频 ±1 个邻位，远离当前视频的自动释放缓冲；
• 支持格式：mp4 / m4v / webm / ogv / ogg / mov / mkv / avi / flv / ts / mpg / mpeg / 3gp / wmv（能否解码取决于 Chromium，常见编码没问题；不支持的编码会显示「无法播放」卡片并自动跳过）。

安全边界

• 宿主半边只注册 /video-player 前缀路由；list/stream 仅 GET/HEAD；写入路由：/video-player/cookies（POST 上传 / DELETE，名称白名单 [A-Za-z0-9][A-Za-z0-9._-]{0,63}、正文 ≤5MB，只写入 ~/.dsh/video-player/cookies/）、/video-player/cache（DELETE，只动插件自己的缓存目录）、/video-player/queue（POST，纯内存推送队列，无文件/网络副作用）；
• 文件访问只允许上述视频扩展名白名单且只允许常规文件；Range 偏移按文件大小校验；
• 目录清单有上限（2000 个 / 深度 8 层），不可读条目静默跳过；
• 可访问路径 = 本机 shell 可读范围（GUI 默认只绑定 127.0.0.1）；
• SMB 输入靠解析 mount 输出换算，凭据不经过本插件（挂载由系统完成：Finder ⌘K / mount_smbfs）；挂载断开后给出「请重新挂载」提示而非裸 EIO 错误。

文件

文件	说明
package.json	包清单 + dsh.bundle（安装层）+ dsh.client（浏览器半边发现）
cordis.patch.yml	由 dsh plugin add 激活的 bundle 补丁层；注册 video-player Loader 行
index.js	宿主半边（node）：/video-player/list（本地目录 + yt-dlp 在线列表）+ /video-player/stream（本地 Range / 在线代理 / DASH 缓存下载）+ /video-player/cookies + /video-player/cache + /video-player/queue，含 SMB 路径解析
client.js	浏览器半边（classic script bundle，无构建步骤）

安装

用 Node.js 安装官方运行时：

npx @deepseek-ai/dsh web

把本插件装入某个 profile（生态约定）：

dsh plugin --profile web add "github:anitman/dsh-plugin-video-player#ref"

dsh plugin 把包操作转发给 pnpm，因此 npm、Git/GitHub、本地路径、file:、link: 等包描述符都支持 —— 例如从本地 clone 安装：

dsh plugin --profile web add .

只有声明了 dsh.bundle.patch 的包才会成为生效的 profile 层；本包已声明，所以 dsh plugin add 一步完成链接与层激活。纯 JS、无构建脚本 —— git 安装不需要 allowBuilds 审批。

安装/更新 bundle 后重启 dsh --profile web 生效：侧栏底部（设置按钮上方）出现「▶ 刷视频」按钮；可在 设置 → 插件 中管理。

卸载

dsh plugin --profile web remove dsh-plugin-video-player

依赖与补丁层一并移除；重启 dsh 生效。

手动安装（不使用 dsh CLI）

1. 在 ~/.dsh/profiles/web/node_modules/ 创建指向本目录的软链接 dsh-plugin-video-player（软链失败则直接拷贝目录）；
2. 在 ~/.dsh/profiles/web/package.json 的 dependencies 中加："dsh-plugin-video-player": "file:<本仓库绝对路径>"；
3. 在 ~/.dsh/profiles/web/cordis.patch.yml 顶层数组追加：

   - insert:
       - id: video-player
         name: "dsh-plugin-video-player"
   

4. 重启 dsh 进程（新 Loader 行只在启动时扫描；会话自动恢复）。

更新

• 只改了 client.js：无需重启，client-HMR 热加载插件（需要宿主侧 watch 链处于活动状态；否则刷新页面）；
• 改了 index.js（宿主半边）：必须重启 dsh；
• 本地 clone 通过 add . 安装的：git pull 后重启 dsh；
• 通过 github: 安装的：带新 #ref 重跑安装命令升级；
• node_modules 里是拷贝而非软链的：改动后重新拷贝（或改回软链）。
