48 服务器此前反馈过内存高。部署 ASR 时应先核对实际可用资源，再使用独立受限 worker；不要在每个 Web 请求内加载一份模型。此处是实施建议，本次没有启动新的常驻模型服务。
|
||||
|
||||
|
||||
## 实施更新
|
||||
|
||||
以上是最初调研时点。已实现的开源分析与剪辑链路、实际验证和独立合成部署状态见 [视频合成服务实施记录](video-render-service-2026-09-17.md)。FunASR仍未完成真实权重验收，不把适配代码等同于转写已可用。

# 视频合成独立服务实施记录
|
||||
|
||||
用户明确只迁移视频合成，其他分析、选片和任务管理保留主项目。新建独立 Node HTTP 服务，复用同一 EDL/FFmpeg 渲染实现；没有重新实现另一套预览/导出时间规则。
|
||||
|
||||
## 算力服务器
|
||||
|
||||
只读检查：shujuku3，AMD EPYC 7B12，64物理核/128线程，125GiB内存，可用约79GiB，根盘空余约151GiB（检查时点）。四张Tesla P40，三张已加载千问模型。现有 `qwen3.8-27b-q4-32k` 三个实例在18230/18231/18233，健康接口均成功；`/props` 明确 vision/video/audio 均为false，只能复用文字能力。
|
||||
|
||||
部署：专用 video-render 用户和 systemd 服务，FFmpeg 6.1.1，已有 Noto CJK 字体。CPUQuota=400%，MemoryHigh=6G，MemoryMax=8G，并发1，监听127.0.0.1:18340。文字助手指向18231，普通合成不调用模型；此轮没有新增模型推理测试或改变现有千问服务配置。
|
||||
|
||||
48 主机通过专用 SSH 隧道访问同一回环端口。新隧道密钥仅允许指定回环监听端口，固定主机公钥，服务另有随机 Bearer 认证。客户端凭据保存在 `/etc/video-render-client.env`，没有提交 Git。
|
||||
|
||||
## 已验证
|
||||
|
||||
- 真实 PySceneDetect 识别三个色块镜头；RMS识别两段有声区间；librosa识别22个节拍。
|
||||
- 真实 FFmpeg：直接拼接4秒、叠化后3.5秒，含无音轨素材、2倍速、配乐和中文字幕。
|
||||
- 独立 HTTP 服务真实测试：无凭据401、同ID重复提交幂等、不同参数409、强制杀进程后重启恢复、完成后重启仍可下载。
|
||||
- 48主机适配器→加密隧道→算力服务→读取成片→现有对象存储归档：720p横屏及1080p竖屏成功。竖屏额外覆盖三片段、非整秒边界、不同速度和0.25秒叠化。
|
||||
- 真实 React 组件操作：添加素材、生成方案、转写未就绪禁用、分割、变速、转场、排序、导出参数、关闭重开恢复、EDL下载。尚需主项目发布后的完整页面验证。
|
||||
- helpers 482项通过，1项跳过；TypeScript通过。真实PostgreSQL队列回归通过。
|
||||
|
||||
## 智能剪辑实现范围
|
||||
|
||||
四种模式、最多三版广告排序、语句/镜头候选、可选千问3.8视觉选片、节拍切镜、去静音、可编辑时间轴和字幕、方案/SRT下载、成片回到画布。模型语义请求状态不明确时禁止重复调用。广告多版本目前是候选排序轮换，不能宣称独立创意脚本生成。
|
||||
|
||||
FunASR适配与安装脚本已实现，未装权重、未做真实ASR验收，界面禁用自动转写并支持导入SRT。当前本地千问接口不能替代视觉选片，视觉分析继续使用主项目已有模型配置。
|
||||
|
||||
部署边界：独立合成服务已启动且两机链路实测通过；主项目正式应用的切换状态将在发布验证后追加。此前音频/导演台等开发分支改动不能凭本记录视为已经上线。

# 智能剪辑处理环境
|
||||
|
||||
从项目根目录运行 `bash services/smart-edit/setup.sh`。准备 Python 3.11、FFmpeg/ffprobe（包含 libx264 与 subtitles/libass）、中文字体（Linux 推荐 Noto Sans CJK）。基础分析依赖按版本固定，虚拟环境独立。
|
||||
|
||||
应用环境配置：
|
||||
|
||||
- `SMART_EDIT_PYTHON=/绝对路径/.venv-smart-edit/bin/python`
|
||||
- `SMART_EDIT_CACHE_DIR=/有足够磁盘空间的私有目录/smart-edit-cache`（缺省 `.cache/smart-edit`）
|
||||
- 运行目录保持项目根目录；Next standalone 打包已包含 analyze.py，Python 与 FFmpeg 单独安装。
|
||||
|
||||
语音识别选装：执行 `bash services/smart-edit/setup.sh --with-asr`，会安装 FunASR/PyTorch 并从 ModelScope 下载官方 Paraformer、FSMN-VAD、CT-Transformer 三个模型。把脚本输出的 `SMART_EDIT_ASR_MODEL`、`SMART_EDIT_VAD_MODEL`、`SMART_EDIT_PUNC_MODEL` 路径写入应用环境。模型代码禁止 trust_remote_code，用户请求不能选择任意模型文件。模型权重下载可能较大，应在维护期间完成；请求阶段仅读取已经配置好的本地模型。
|
||||
|
||||
诊断：`$SMART_EDIT_PYTHON services/smart-edit/analyze.py --check`。API `/api/canvas/smart-edit/capabilities` 仅对登录用户返回可用功能与模型列表，不返回密钥或本地路径。ASR 未准备好时页面关闭自动转写选项，仍可导入 SRT 和进行画面混剪。
|
||||
|
||||
资源：整个智能剪辑作业通过 PostgreSQL advisory lock 限制为同一数据库下同时一个重处理任务，租约心跳沿用画布任务队列。Python/FFmpeg 限制线程数，单素材 ≤180 秒、≤125 MiB、至多6份，总素材≤10分钟，成片≤90秒、≤12片段；分析缓存按用户隔离，内容 hash 校验，7天过期、4GiB上限。低清代理仅用于分析，成片使用原素材。数据库锁繁忙时任务保存为可恢复状态，页面轮询或返回画布会继续运行。
|
||||
|
||||
算法：PySceneDetect 检测镜头，librosa 检测节拍，FunASR 返回语句时间戳（采用 FunClip 的时间戳剪辑思路）。去静音为独立实现的 RMS 阈值算法，参考 Auto-Editor 的粗剪与余量机制；没有复制 Auto-Editor 或 FunClip 源码，也不依赖它们的 UI。来源与许可证记录在项目 docs/video-canvas-smart-edit-research-2026-09-17.md。PySceneDetect 为 BSD-3-Clause，librosa 为 ISC，FunASR 源码和各权重许可应按所安装版本一并保留。
|
||||
|
||||
智能选片直接复用项目内官方千问3.8视觉模型；关闭智能选片后所有镜头/节拍/剪辑流程均为本地运算。供应商受理状态不明的语义请求不会自动重发。素材文本和字幕仅为待分析数据，模型只允许返回实际候选ID，不能生成任意时间区间、文件路径或命令。
|
||||
|
||||
预览使用同一 EDL 的时间、裁剪、速度、音量和叠化参数；浏览器流式预览受网络和解码影响。最终导出由 FFmpeg 确定性合成。音乐文件不足时末尾补静音，不默认循环；背景音量由用户调整。字幕样式与浏览器字体可能有差异。广告多版本目前对候选排序作轮换，素材不足时明确提示，不宣称独立生成多个创意脚本。
|
||||
|
||||
|
||||
远程合成：设置 `SMART_EDIT_RENDER_URL` 与 `SMART_EDIT_RENDER_TOKEN` 后，render操作进入独立API，不占用本地主处理锁。独立服务部署见 `../video-render/README.md`，其千问仅提供可选文字能力。分析操作仍使用本机Python/代理文件。

# 独立视频合成服务
|
||||
|
||||
只承接已确认的 EDL 合成。主项目保留用户鉴权、项目、分析选片、时间轴与最终对象存储归档；算力服务器下载原素材、校验内容 hash，用 FFmpeg 处理剪裁、速度、音量、转场、字幕和配乐。没有把完整主项目、数据库密码或云模型密钥复制到算力服务器。
|
||||
|
||||
## 运行
|
||||
|
||||
项目根目录执行 `node services/video-render/build.cjs`，生成不依赖主项目 node_modules 的 `dist/server.cjs`（Node 22，Zod 随包打包）。机器需要 FFmpeg/ffprobe、libx264、libass、中文字体。发布包放 `/opt/video-render/releases/<hash>/server.cjs`，`current` 指向当前版本。参见 `video-render.service`：专用低权限用户、单 worker、4 核 CPU 配额、6 GiB 内存软限制 / 8 GiB 硬限制。当前使用 CPU，不占用千问显卡。
|
||||
|
||||
`/etc/video-render.env` 权限 600，环境变量：
|
||||
|
||||
- `RENDER_API_TOKEN`：至少 32 字符随机凭据，不能提交 Git。
|
||||
- `RENDER_HOST=127.0.0.1`、`RENDER_PORT=18340`。
|
||||
- `RENDER_DATA_DIR=/var/lib/video-render`。
|
||||
- `SMART_EDIT_CACHE_DIR=/var/lib/video-render/cache`。
|
||||
- 可选 `RENDER_QWEN_URL=http://127.0.0.1:18231/v1`、`RENDER_QWEN_MODEL=qwen3.8-27b-q4-32k`。
|
||||
|
||||
主项目配置 `SMART_EDIT_RENDER_URL=http://127.0.0.1:18340` 和同值 `SMART_EDIT_RENDER_TOKEN`。只要配置远程服务，合成请求走远程；远程连接失败不会悄悄回退到主机 FFmpeg。已有远程任务绑定原服务地址，不能在恢复时切换到另一台重复提交。
|
||||
|
||||
两台服务器通过专用 SSH 反向隧道连接，参见 `video-render-tunnel.service`。48 上专用隧道用户只允许监听 `127.0.0.1:18340`，禁用命令、PTY、代理转发，主机公钥预先核对并固定；私钥仅留算力服务器，不使用或复制管理员私钥。合成 API 仍要求 Bearer 凭据。容器部署时 localhost 含义不同，必须显式配置宿主机访问方式。
|
||||
|
||||
## 接口
|
||||
|
||||
所有接口要求 `Authorization: Bearer <token>`，不接受浏览器直接访问。
|
||||
|
||||
- `GET /health`：队列数量、活动任务数、合成方式、文字助手是否配置。
|
||||
- `POST /v1/renders`：`{id, tenant, plan}`；id 与 tenant 均为 SHA-256 十六进制标识，plan 使用 `lib/video-canvas/smart-edit/contract.ts`。
|
||||
- `GET /v1/renders/:id`：`queued/running/succeeded/failed`、阶段、重试次数、结果尺寸及时长。
|
||||
- `GET /v1/renders/:id/video`、`/subtitles`：鉴权下载产物，由主项目归档。
|
||||
- `POST /v1/assist`：可选 `{instruction, context}` 文本辅助，返回建议文字；不自动改变剪辑方案、不执行生成的代码、不支持图片视频输入。并发 1，90 秒超时，不自动重试。普通合成不会调用千问。
|
||||
|
||||
任务 ID 由主项目持久任务号导出：重复 POST 返回同一记录，参数改变返回 409。写盘采用临时文件、fsync、rename 后再响应。单服务进程拥有此数据目录，不能启动多个副本共用目录。服务重启后运行中任务最多恢复两次；完成记录重启后仍可下载。主项目轮询超时保存编号继续查询，不受浏览器页面生命周期限制。
|
||||
|
||||
上限：请求 1 MiB，至多 30 个等待/运行任务，至多 200 个保留任务；完成/失败记录和产物保留 7 天，小时清理；原素材缓存按用户隔离，4 GiB / 7 天清理；素材 ≤125 MiB/份、≤180秒/份、≤6份且总长≤10分钟，成片≤90秒/12片段。磁盘可用不足10GiB拒绝重处理。外部素材禁止内网地址，DNS验证后绑定地址下载，每次重定向重新验证；FFmpeg禁用网络输入协议。
|
||||
|
||||
## 验证
|
||||
|
||||
`PATH=<ffmpeg目录>:$PATH node scripts/qa/video-canvas-smart-edit.cjs` 生成合成素材并验证 FFmpeg。设置 `SMART_EDIT_PYTHON` 可同时验证真实 PySceneDetect、RMS、librosa。
|
||||
|
||||
随后 `node services/video-render/build.cjs && PATH=<ffmpeg目录>:$PATH node scripts/qa/video-render-service.cjs` 验证真实 HTTP、鉴权、FFmpeg、进程强制中断/恢复、幂等、冲突拒绝和完成记录重启保留。用合成色块/正弦音，不调用付费模型。
|
||||
|
||||
依赖许可：Zod MIT；FFmpeg 许可取决于本机编译选项，Ubuntu libx264 构建含 GPL 组件。服务只运行本机已安装 FFmpeg，不把二进制混入仓库。代码与发布状态记录在 `docs/video-render-service-2026-09-17.md`。
