Merge pull request 'fix(P0): 移除 MCI 插帧，60fps 视频直接输出 25fps 避免超时 504' (#2008) from fix/remove-mci-interpolation into develop

- 移除 Step 8 的 minterpolate MCI 运动补偿插帧（CPU密集，343帧超6分钟导致超时504）
- 高帧率视频降帧至 25fps 后直接输出，对口型数字人场景完全够用
- 插帧失败不再导致整个任务 504，直接降级返回 25fps 结果

+# MuseTalk GPU Worker 部署指南
+
+本目录包含两个组件：
+
+1. **gpu_worker.py**：反向轮询客户端，部署在 RTX2060 本地，轮询 SaaS API 拉取口型任务，调用本地 MuseTalk 服务推理，上传结果回 SaaS。
+2. **musetalk_server.py**：MuseTalk Flask HTTP 服务端，接收 gpu_worker.py 的推理请求，调用 MuseTalk 模型生成口型同步视频。
+
+---
+
+## 一、环境准备
+
+### 1.1 硬件要求
+
+- GPU: NVIDIA RTX 2060 或更高（显存 ≥ 6GB）
+- CUDA: 11.8+
+- Python: 3.10+
+- ffmpeg: 需安装并加入 PATH
+
+### 1.2 安装依赖
+
+```bash
+cd deploy/gpu_worker
+python3 -m venv venv
+source venv/bin/activate
+pip install -r requirements.txt
+```
+
+---
+
+## 二、MuseTalk 服务端部署（musetalk_server.py）
+
+### 2.1 配置环境变量
+
+复制 `.env.example` 为 `.env`，修改配置：
+
+```bash
+cp .env.example .env
+vim .env
+```
+
+关键配置：
+
+| 变量 | 说明 | 默认值 |
+|------|------|--------|
+| `MUSE_PORT` | 监听端口 | `7861` |
+| `MUSE_INFERENCE_TIMEOUT` | 推理超时秒数 | `600` |
+| `MUSE_VIDEO_MAX_MB` | 视频上传大小限制 MB | `100` |
+| `MUSE_AUDIO_MAX_MB` | 音频上传大小限制 MB | `20` |
+| `MUSE_DEFAULT_FPS` | 视频 fps 兜底值 | `25.0` |
+| `MUSE_TEMP_DIR` | 临时文件目录 | `/tmp/musetalk_$$` |
+| `MUSE_VIDEO_ENCODER` | 兜底循环视频时的编码器：`auto`（优先 h264_nvenc，失败回退 libx264）/`h264_nvenc`/`libx264` | `auto` |
+
+### 2.2 更新部署（v2 性能修复，必做）
+
+> ⚠️ 2026-09-20 v2 架构：修复 16 倍性能回归。旧版在推理前 loop 视频导致 MuseTalk 处理帧数翻倍、RTX2060 推理 >200s、nginx 504。**必须重新拉取并重启**：
+
+```bash
+# 在 RTX2060 上备份旧文件并拉取新版本
+cp ~/projects/MuseTalk/musetalk_server.py ~/projects/MuseTalk/musetalk_server.py.bak
+wget -O ~/projects/MuseTalk/musetalk_server.py \
+  "https://git.xiaoxiajianji.com/xiaoxia/xiaoxia-saas/raw/branch/develop/deploy/gpu_worker/musetalk_server.py"
+
+# 重启服务
+sudo systemctl restart musetalk-server
+sudo systemctl status musetalk-server
+curl http://127.0.0.1:7861/health
+```
+
+v2 架构核心变化：
+
+- **MuseTalk 直传全量音频**：不再在推理前用 ffmpeg 循环视频。MuseTalk 原生支持长音频输入，内部自动循环视频帧。推理时间不变（~14s/5s 视频）
+- **ffmpeg 只做快速封装**：`-c:v copy -c:a aac -shortest`，秒级完成，不重编码
+- **循环仅兜底**：仅当 MuseTalk 输出画面短于音频时（极端情况），才 `-stream_loop` + NVENC 兜底
+- **删除 `MUSE_ENABLE_VIDEO_LOOP`**：不再需要此开关，MuseTalk 原生处理
+
+### 2.3 启动服务
+
+```bash
+# 前台运行（调试用）
+python musetalk_server.py
+
+# 后台运行（生产用 systemd）
+sudo systemctl start musetalk-server
+sudo systemctl enable musetalk-server
+```
+
+### 2.4 验证健康检查
+
+```bash
+curl http://127.0.0.1:7861/health
+```
+
+应返回：
+
+```json
+{
+  "status": "healthy",
+  "gpu": {
+    "gpu_name": "NVIDIA GeForce RTX 2060",
+    "memory_total_mb": 6144,
+    "memory_used_mb": 1024,
+    "memory_free_mb": 5120
+  },
+  "current_task": {
+    "task_id": null,
+    "running": false,
+    "elapsed_seconds": 0.0
+  },
+  "timestamp": 1700000000.0
+}
+```
+
+---
+
+## 三、GPU Worker 客户端部署（gpu_worker.py）
+
+### 3.1 配置环境变量
+
+复制 `.env.example` 为 `.env`，修改配置：
+
+```bash
+cp .env.example .env
+vim .env
+```
+
+关键配置：
+
+| 变量 | 说明 | 默认值 |
+|------|------|--------|
+| `API_BASE_URL` | SaaS API 基础 URL | `https://staging-api.xiaoxiajianji.com` |
+| `GPU_WORKER_TOKEN` | 长期 API Token（与服务端一致） | - |
+| `MUSE_TALK_URL` | 本地 MuseTalk 服务地址 | `http://127.0.0.1:7861` |
+| `POLL_INTERVAL` | 轮询间隔秒 | `5` |
+| `HEARTBEAT_INTERVAL` | 空闲心跳间隔秒 | `15` |
+| `REQUEST_TIMEOUT` | HTTP 请求超时秒 | `900` |
+| `TASK_MAX_RETRY` | 本地最大重试次数 | `1` |
+| `TASK_HEARTBEAT_INTERVAL` | 推理期间任务心跳间隔秒 | `30` |
+| `MIN_VIDEO_DURATION_SECONDS` | 最短输入视频时长秒 | `3` |
+
+### 3.2 启动 Worker
+
+```bash
+# 前台运行（调试用）
+python gpu_worker.py
+
+# 后台运行（生产用 systemd）
+sudo systemctl start xiaoxia-gpu-worker
+sudo systemctl enable xiaoxia-gpu-worker
+```
+
+### 3.3 验证启动日志
+
+应看到：
+
+```
+============================================================
+MuseTalk GPU Worker 启动
+  worker_id   = rtx2060-xxxx
+  api_base    = https://staging-api.xiaoxiajianji.com
+  muse_talk   = http://127.0.0.1:7861
+  poll        = 5.0s / heartbeat = 15.0s
+============================================================
+MuseTalk 健康检查通过: {...}
+注册/心跳成功
+```
+
+---
+
+## 四、常见问题排查
+
+| 现象 | 可能原因 / 排查 |
+|---|---|
+| 日志 401 `Invalid GPU worker token` | `.env` 的 `GPU_WORKER_TOKEN` 与服务端不一致 |
+| 日志 `MuseTalk 健康检查未通过` | 本地 MuseTalk 没启动，或端口不是 7861；`curl http://127.0.0.1:7861/health` 验证 |
+| 任务长时间不被拉取 | Worker 和服务端连不上；检查 API_BASE_URL 是否可达、Token 是否正确 |
+| 推理后上传 OSS 失败 | 本地出口网络被防火墙拦截 OSS 域名（oss-cn-hangzhou.aliyuncs.com） |
+| 服务端看到任务回退到 pending 重试 | 任务心跳真正超时（默认 900s）：Worker 进程崩溃/断网，或推理彻底卡死；正常长推理期间心跳线程每 30s 续期，不会回退 |
+| 日志 `MuseTalk 推理超时或连接失败` | 视频太长或显存不足；可临时调大 REQUEST_TIMEOUT（服务端 GPU_TASK_TIMEOUT_SECONDS 需同步调大），或限制输入视频时长 |
+| 日志 `视频过短（x.xxs < 3s）` | 输入视频不足 3s，MuseTalk 对短视频会 division by zero，已在本地直接上报失败；可用 MIN_VIDEO_DURATION_SECONDS 调整阈值 |
+| MuseTalk 服务端 503 `GPU 正在处理其他任务` | 并发请求被锁拒绝，等当前推理完成即可 |
+| MuseTalk 服务端 504 `推理超时` | 推理超过 MUSE_INFERENCE_TIMEOUT，客户端会调 /cancel 终止服务端任务 |
+
+---
+
+## 五、安全注意事项
+
+- `.env` 包含长期 Token，文件权限设为 600（`chmod 600 .env`）
+- Token 泄露要立即在服务端更换 `GPU_WORKER_TOKEN` 并重启 Worker
+- Worker 只需要出站访问 SaaS API 和 OSS，不需要开放任何入站端口
+- MuseTalk 服务端只监听本地 127.0.0.1（或 0.0.0.0 但通过防火墙限制），不暴露到公网
+- 临时文件自动清理（推理完成/失败后），无需手动维护
+
+---
+
+## 六、工程改进记录（musetalk_server.py）
+
+相比原 `worker.py`，修复了以下 8 个 bug：
+
+1. **Flask 单线程阻塞**：`app.run(threaded=True)`，推理时 `/health` 仍可响应
+2. **fps=0 除零崩溃**：`_get_video_fps()` 兜底 `MUSE_DEFAULT_FPS`
+3. **ffmpeg 不检查返回码**：`subprocess.run(check=True)` + 超时检查，失败立即报错
+4. **无并发锁**：`threading.Lock` 控制并发，第二请求立即 503
+5. **无推理超时**：线程 join timeout，超时返回 504 并调 `/cancel`
+6. **结果文件不清理**：推理完成/失败后自动删除临时目录
+7. **无人脸检测兜底**：MuseTalk 推理内部处理（TODO: 可在 `_run_inference` 前置检查）
+8. **上传无大小限制**：`_check_file_size()` 校验，超限返回 413
+
+新增：
+- `/cancel` 端点：终止当前推理任务，清理临时文件
+- `/health` 端点：返回 GPU 显存信息和当前任务状态
+
+2026-09-20 追加修复（音轨正确性，上线阻断级）：
+
+9. **音轨未替换（严重）**：旧最终封装让 ffmpeg 默认选流，结果保留了源视频自带音轨（与画面相关系数 0.9998，与 TTS 无关）。改为 `_mux_video_with_audio()` 统一封装，强制 `-map 0:v:0 -map 1:a:0`，画面取 MuseTalk 无声产物、音轨只取驱动音频
+10. **音视频时长不对齐**：TTS 长于原视频时 `-shortest` 会截短语音。改为探测双方时长，音频更长时 `-stream_loop -1` 循环画面 + `h264_nvenc` 硬件重编码（`MUSE_VIDEO_ENCODER=auto`，失败回退 libx264）+ `-t <音频时长>`；不循环时 `-c:v copy` 秒封装
+    - 开关 `MUSE_ENABLE_VIDEO_LOOP=0` 可关闭循环；请求也支持 form 参数 `enable_video_loop` 单任务覆盖
+
+2026-09-20 v2 架构重构（性能回归修复，上线阻断级）：
+
+11. **16 倍性能回归**：#9/#10 的实现虽然音轨正确，但在某些集成场景下（推理前 loop 视频再喂 MuseTalk）导致推理帧数 ×2.2 + 叠加 ffmpeg 软编码预处理，5s 视频 +11s 音频推理 >200s，nginx 60s 超时 504
+    - **正确架构**：MuseTalk 原生支持长音频输入，内部自动循环视频帧。把【原视频】+【全量音频】直传 MuseTalk，输出时长=音频时长
+    - **ffmpeg 后置快速封装**：`-c:v copy -c:a aac -shortest` 秒级完成，不重编码
+    - **循环仅兜底**：仅当 MuseTalk 输出画面短于音频时（极端情况），才 `-stream_loop` + NVENC 兜底补齐
+    - **业务侧异步化**：POST /lipsync/jobs 创建 GPU 任务后立即返回 `job.status="processing"`，Celery 异步等待结果回写。前端 GET /jobs/{id} 轮询。避免同步阻塞 HTTP 请求 >200s
+    - **删除 `MUSE_ENABLE_VIDEO_LOOP`**：不再需要此开关
+
+---
+
+## 七、自动部署
+
+从 2026-09-20 起，GPU 节点配置文件和脚本全部入库到 `deploy/gpu_worker/`，支持一键初始化新节点 + develop 分支 push 后 30 秒内自动拉取更新。
+
+### 7.1 服务架构
+
+每个 GPU 渲染节点运行三个 systemd 单元：
+
+| 单元 | 类型 | 作用 |
+|---|---|---|
+| `musetalk-worker.service` | simple（常驻） | MuseTalk Flask 推理 API（监听 127.0.0.1:7861） |
+| `xiaoxia-gpu-worker.service` | simple（常驻） | 反向轮询 SaaS API 拉口型任务的 Worker 客户端 |
+| `gpu-poll.timer` + `gpu-poll.service` | timer（每 30s 触发 oneshot） | 轮询 Gitea `deploy/gpu_worker/` 最新 commit，有变更自动执行 update 脚本 |
+
+脚本目录（节点本地）：
+
+| 路径 | 来源 | 作用 |
+|---|---|---|
+| `~/projects/update-gpu-worker.sh` | `scripts/update-gpu-worker.sh` | 备份 → 拉代码 → 重启两个服务 → 健康检查 → 失败回滚 |
+| `~/projects/gpu-webhook/poll_and_update.sh` | `scripts/poll_and_update.sh` | 轮询 Gitea API 比对 SHA，有新 commit 时触发 update |
+
+### 7.2 新节点部署步骤
+
+**前置准备**（手动，首次部署必做）：
+
+1. 安装 NVIDIA 驱动 + CUDA 11.8+，`nvidia-smi` 能看到 GPU
+2. 克隆 MuseTalk 代码到 `~/projects/MuseTalk/`，下载模型权重到 `~/projects/MuseTalk/models/musetalk/`（权重约几 GB，不适合自动下载）
+3. 创建 Python 虚拟环境 `~/projects/MuseTalk/venv/` 并安装 MuseTalk 依赖（PyTorch CUDA 版等）
+4. 创建 Worker 虚拟环境 `/opt/xiaoxia-gpu-worker/venv/` 并 `pip install -r requirements.txt`
+5. 准备 `.env` 文件（Worker 端）：`/opt/xiaoxia-gpu-worker/.env`，填好 `API_BASE_URL`、`GPU_WORKER_TOKEN`、`MUSE_TALK_URL` 等（参考 `.env.example`）
+
+> ⚠️ 模型权重和 Python 虚拟环境（含 CUDA 版 PyTorch）体积大、安装慢，首次部署必须手动准备；后续脚本只更新 `.py` 文件和配置，不碰权重和 venv。
+
+**一键初始化**：
+
+```bash
+# 从仓库拉取 setup 脚本并执行（在全新 GPU 机器上以 ying 用户执行）
+wget -q -O /tmp/setup-gpu-node.sh \
+  "https://git.xiaoxiajianji.com/xiaoxia/xiaoxia-saas/raw/branch/develop/deploy/gpu_worker/scripts/setup-gpu-node.sh"
+bash /tmp/setup-gpu-node.sh
+```
+
+脚本自动完成：
+
+1. apt 安装系统依赖（python3、ffmpeg、wget、curl、git）
+2. 创建必要目录（`~/projects/MuseTalk`、`~/projects/gpu-webhook`、`/opt/xiaoxia-gpu-worker`）
+3. 从仓库拉取三个 systemd 单元文件 + update/poll 脚本到本地
+4. 安装 systemd 服务到 `/etc/systemd/system/`
+5. 配置 sudo 免密（仅允许 `ying` 用户免密 restart 两个服务、status、journalctl、cp、chmod、tee）
+6. 首次执行 update 脚本拉取最新 `musetalk_server.py` 和 `gpu_worker.py`
+7. `systemctl daemon-reload` + enable + start 三个单元
+
+**初始化后检查**：
+
+```bash
+sudo systemctl status musetalk-worker       # 应 active (running)
+sudo systemctl status xiaoxia-gpu-worker    # 应 active (running)
+sudo systemctl status gpu-poll.timer        # 应 active (waiting)
+curl http://127.0.0.1:7861/health          # 应返回 healthy + GPU 显存信息
+```
+
+### 7.3 自动更新机制
+
+push 到 `develop` 分支且修改了 `deploy/gpu_worker/` 下任何文件后：
+
+1. `gpu-poll.timer` 每 30 秒触发 `gpu-poll.service`
+2. `poll_and_update.sh` 调用 Gitea API 取 `deploy/gpu_worker/` 路径最新 commit SHA
+3. 与本地 `~/projects/gpu-webhook/.last_commit` 比对，无变更直接退出
+4. 有变更：写入新 SHA → 执行 `update-gpu-worker.sh`
+5. `update-gpu-worker.sh` 执行流程：
+   - 备份当前 `musetalk_server.py` / `gpu_worker.py`（带时间戳后缀）
+   - wget 拉取最新 `musetalk_server.py`、`gpu_worker.py`
+   - 比对 `requirements.txt`，有变化则 pip install
+   - `sudo systemctl restart musetalk-worker`，等 5 秒
+   - `sudo systemctl restart xiaoxia-gpu-worker`，等 8 秒
+   - `curl http://127.0.0.1:7861/health` 健康检查
+   - 健康 → 写日志退出 0
+   - 不健康 → 回滚到最新备份 → 重启 → 退出 1（日志记录 rolled back）
+
+端到端延迟：从 push 到节点拉到新代码并重启，约 30~60 秒。
+
+### 7.4 手动更新命令
+
+```bash
+# 立即手动触发一次更新（不依赖 timer）
+bash ~/projects/update-gpu-worker.sh
+
+# 查看更新日志
+tail -f /tmp/gpu-worker-update.log
+
+# 查看轮询日志
+tail -f /tmp/gpu-poll.log
+
+# 查看服务运行日志
+journalctl -u musetalk-worker -f          # MuseTalk 推理服务日志
+journalctl -u xiaoxia-gpu-worker -f       # GPU Worker 客户端日志
+journalctl -u gpu-poll.service -f         # 轮询/更新触发日志
+```
+
+### 7.5 仓库文件清单（自动部署相关）

+
+### 7.6 注意事项
+
+- **首次部署必须手动准备**：MuseTalk 代码仓库、模型权重（`models/musetalk/`，几 GB）、MuseTalk 的 Python 虚拟环境（`venv/`，含 CUDA 版 PyTorch）。这些体积大、安装耗时长，不在自动更新范围内。
+- **脚本路径写死**：当前脚本路径固定为 `/home/ying/projects/` 和 `/opt/xiaoxia-gpu-worker/`，用户名固定 `ying`。后续如有多节点/多用户需求再做参数化。
+- **sudo 免密范围最小化**：setup 脚本写入 `/etc/sudoers.d/ying-gpu-update`，仅放行 restart/status 两个 GPU 相关服务、daemon-reload、journalctl、cp、chmod、tee，不开放全量 root。
+- **回滚只回滚 .py 文件**：健康检查失败只回滚 `musetalk_server.py` 和 `gpu_worker.py`，不回滚 pip 依赖（requirements.txt 变化概率低，且 pip 操作本身可能失败）。如需完全回滚，手动 `pip install -r requirements.txt` 指定旧版本。
+- **poll 脚本容错**：Gitea API 请求失败直接跳过，不触发更新，不会因为网络抖动误重启服务。
