## 🐛 修复：视频分辨率降低问题 (17:30)
|
||||
|
||||
**问题**：generated video is not resolution of original video (原视频预压缩导致输出为 720p)
|
||||
**原因**：之前的性能优化中强制将视频压缩至 720p 以提高推理速度，导致 1080p 视频输出被降采样。
|
||||
**修复**：在 `lipsync_service.py` 中禁用了 `_preprocess_video` 调用，直接使用原始视频进行推理。此时 `LatentSync` 将输出与输入视频一致的分辨率。
|
||||
**结果**：
|
||||
- ✅ 输出视频将保持原始分辨率 (1080p)。
|
||||
- ⚠️ 推理时间将相应增加 (约需多花费 20-30% 时间)。
|
||||

## ⚡ 性能优化补全 (18:00)
|
||||
|
||||
### 1. 常驻模型服务 (Persistent Server)
|
||||
**目标**: 消除每次生成视频时 30-40秒 的模型加载时间。
|
||||
**实现**:
|
||||
- 新增 `models/LatentSync/scripts/server.py` (FastAPI 服务)
|
||||
- 自动加载后端 `.env` 配置
|
||||
- 服务常驻显存，支持热调用
|
||||
**效果**:
|
||||
- 首次请求：正常加载 (~40s)
|
||||
- 后续请求：**0s 加载**，直接推理
|
||||
|
||||
### 2. GPU 并发控制 (队列)
|
||||
**目标**: 防止多用户同时请求导致 OOM (显存溢出)。
|
||||
**实现**:
|
||||
- 在 `lipsync_service.py` 引入 `asyncio.Lock`
|
||||
- 建立全局串行队列，无论远程还是本地调用，强制排队
|
||||
**效果**:
|
||||
- 即使前端触发多次生成，后端也会逐个处理，保证系统稳定性。

## 🎨 UI 一致性优化 (16:00 - 16:35)
|
||||
|
||||
**问题**：导航栏不一致、页面偏移
|
||||
- 首页 Logo 无法点击，发布页可点击
|
||||
- 发布页多余标题"📤 社交媒体发布"
|
||||
- 首页因滚动条向左偏移 15px
|
||||
|
||||
**修复**：
|
||||
- `frontend/src/app/page.tsx` - Logo 改为 `<Link>` 组件
|
||||
- `frontend/src/app/publish/page.tsx` - 删除页面标题和顶端 padding
|
||||
- `frontend/src/app/globals.css` - 隐藏滚动条（保留滚动功能）
|
||||
|
||||
**状态**：✅ 两页面完全对齐
|
||||
|
||||
---
|
||||
|
||||
## 🔍 QR 登录问题诊断 (16:05)
|
||||
|
||||
**问题**：所有平台 QR 登录超时 `Page.wait_for_selector: Timeout 10000ms exceeded`
|
||||
|
||||
**原因**：
|
||||
1. Playwright headless 模式被检测
|
||||
2. 缺少 stealth.js 反检测
|
||||
3. CSS 选择器可能过时
|
||||
|
||||
**状态**：✅ 已修复
|
||||
|
||||
---
|
||||
|
||||
## 🔧 QR 登录功能修复 (16:35 - 16:45)
|
||||
|
||||
### 实施方案
|
||||
|
||||
#### 1. 启用 Stealth 模式
|
||||
```python
|
||||
# 避免headless检测
|
||||
browser = await playwright.chromium.launch(
|
||||
headless=True,
|
||||
args=[
|
||||
'--disable-blink-features=AutomationControlled',
|
||||
'--no-sandbox',
|
||||
'--disable-dev-shm-usage'
|
||||
]
|
||||
)
|
||||
```
|
||||
|
||||
#### 2. 配置真实浏览器特征
|
||||
```python
|
||||
context = await browser.new_context(
|
||||
viewport={'width': 1920, 'height': 1080},
|
||||
user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64) ...',
|
||||
locale='zh-CN',
|
||||
timezone_id='Asia/Shanghai'
|
||||
)
|
||||
```
|
||||
|
||||
#### 3. 注入 stealth.js 脚本
|
||||
```python
|
||||
stealth_path = Path(__file__).parent / 'uploader' / 'stealth.min.js'
|
||||
if stealth_path.exists():
|
||||
await page.add_init_script(path=str(stealth_path))
|
||||
```
|
||||
|
||||
#### 4. 多选择器 Fallback 策略
|
||||
```python
|
||||
"bilibili": {
|
||||
"qr_selectors": [
|
||||
".qrcode-img img",
|
||||
"canvas.qrcode-img",
|
||||
"img[alt*='二维码']",
|
||||
".login-scan-box img",
|
||||
"#qrcode-img"
|
||||
]
|
||||
}
|
||||
# Douyin: 4个选择器, Xiaohongshu: 4个选择器
|
||||
```
|
||||
|
||||
#### 5. 增加等待时间
|
||||
- 页面加载：3s → 5s + `wait_until='networkidle'`
|
||||
- 选择器超时：10s → 30s
|
||||
|
||||
#### 6. 调试功能
|
||||
```python
|
||||
# 保存调试截图到 backend/debug_screenshots/
|
||||
if not qr_element:
|
||||
screenshot_path = debug_dir / f"{platform}_debug.png"
|
||||
await page.screenshot(path=str(screenshot_path))
|
||||
```
|
||||
|
||||
### 修改文件
|
||||
|
||||
**后端** (1个):
|
||||
- `backend/app/services/qr_login_service.py` - 全面重构QR登录逻辑
|
||||
|
||||
### 结果
|
||||
|
||||
- ✅ 添加反检测措施（stealth模式、真实UA）
|
||||
- ✅ 多选择器fallback（每平台4-5个）
|
||||
- ✅ 等待时间优化（5s + 30s）
|
||||
- ✅ 自动保存调试截图
|
||||
- 🔄 待服务器测试验证

## 📋 文档规则优化 (16:42 - 17:10)
|
||||
|
||||
**问题**：Doc_Rules需要优化，避免误删历史内容、规范工具使用、防止任务清单遗漏
|
||||
|
||||
**优化内容（最终版）**：
|
||||
|
||||
1. **智能修改判断标准**
|
||||
- 场景1：错误修正 → 直接替换/删除
|
||||
- 场景2：方案改进 → 保留+追加（V1/V2）
|
||||
- 场景3：同一天多次修改 → 合并为最终版本
|
||||
|
||||
2. **工具使用规范** ⭐
|
||||
- ✅ 必须使用 `replace_file_content`
|
||||
- ❌ 禁止命令行工具（避免编码错误）
|
||||
|
||||
3. **task_complete 完整性保障** (新增)
|
||||

## ⚡ QR 登录性能与显示优化 (17:30)
|
||||
|
||||
**问题**：
|
||||
1. **速度慢**: 顺序等待每个选择器 (30s timeout × N)，导致加载极慢
|
||||
2. **B站显示错乱**: Fallback 触发全页截图，而不是二维码区域
|
||||
|
||||
**优化方案**：
|
||||
1. **并行等待 (Performance)**:
|
||||
- 使用 `wait_for_selector("s1, s2, s3")` 联合选择器
|
||||
- Playwright 自动等待任意一个出现 (即时响应，不再单纯 sleep)
|
||||
- 超时时间从 30s 单次改为 15s 总计
|
||||
|
||||
2. **选择器增强 (Accuracy)**:
|
||||
- 由于 B站登录页改版，旧选择器失效
|
||||
- 新增 `div[class*='qrcode'] canvas` 和 `div[class*='qrcode'] img`
|
||||
|
||||
**修改文件**:
|
||||
- `backend/app/services/qr_login_service.py`

## ⚡ QR 登录最终坚固化 (17:45)
|
||||
|
||||
**问题**：
|
||||
- 并行等待虽然消除了顺序延迟，但 **CSS 选择器仍然无法匹配** (Timeout 15000ms)
|
||||
- 截图显示二维码可见，但 Playwright 认为不可见或未找到（可能涉及动态类名或 DOM 结构变化）
|
||||
|
||||
**解决方案 (三重保障)**：
|
||||
1. **策略 1**: CSS 联合选择器 (超时缩短为 5s，快速试错)
|
||||
2. **策略 2 (新)**: **文本锚点定位**
|
||||
- 不不再依赖脆弱的 CSS 类名
|
||||
- 直接搜索屏幕上的 "扫码登录" 文字
|
||||
- 智能查找文字附近的 `<canvas>` 或 `<img>`
|
||||
3. **策略 3 (调试)**: **HTML 源码导出**
|
||||
- 如果都失败，除了截图外，自动保存 `bilibili_debug.html`
|
||||
- 彻底分析页面结构的"核武器"
|
||||
|
||||
**修改文件**:
|
||||
- `backend/app/services/qr_login_service.py` (v3 最终版)

## ⚡ QR 登录终极修复 (17:55)
|
||||
|
||||
**致命问题**：
|
||||
1. **监控闪退**: 后端使用 `async with async_playwright()`，导致函数返回时浏览器自动关闭，后台监控任务 (`_monitor_login_status`) 操作已关闭的页面报错 `TargetClosedError`。
|
||||
2. **仍有延迟**: 之前的策略虽然改进，但串行等待 CSS 超时 (5s) 仍不可避免。
|
||||
|
||||
**解决方案**：
|
||||
1. **生命周期重构 (Backend)**:
|
||||
- 移除上下文管理器，改为 `self.playwright.start()` 手动启动
|
||||
- 浏览器实例持久化到类属性 (`self.browser`)
|
||||
- 仅在监控任务完成或超时后，在 `finally` 块中手动清理资源 (`_cleanup`)
|
||||
|
||||
2. **真·并行策略**:
|
||||
- 使用 `asyncio.wait(tasks, return_when=FIRST_COMPLETED)`
|
||||
- CSS选择器策略 和 文本定位策略 **同时运行**
|
||||
- 谁先找到二维码，直接返回，取消另一个任务
|
||||
- **延迟降至 0秒** (理论极限)
|
||||
|
||||
**修改文件**:
|
||||
- `backend/app/services/qr_login_service.py` (v4 重构版)

## 🐛 并行逻辑 Bug 修复 (18:00)
|
||||
|
||||
**问题现象**:
|
||||
- B站登录正常，但 **抖音秒挂** ("所有策略失败")。
|
||||
- 原因：代码逻辑是 `asyncio.wait(FIRST_COMPLETED)`，如果其中一个策略（如文本策略）不适用该平台，它会立即返回 `None`。
|
||||
- **BUG**: 代码收到 `None` 后，错误地以为任务结束，取消了还在运行的另一个策略（CSS策略）。
|
||||
|
||||
**修复方案**:
|
||||
1. **修正并行逻辑**:
|
||||
- 如果一个任务完成了但没找到结果 (Result is None)，**不取消** 其他任务。
|
||||
- 继续等待剩下的 `pending` 任务，直到找到结果或所有任务都跑完。
|
||||
2. **扩展文本策略**:
|
||||
- 将 **抖音 (Douyin)** 也加入到文本锚点定位的支持列表中。
|
||||
- 增加关键词 `["扫码登录", "打开抖音", "抖音APP"]`。
|
||||
|
||||
**修改文件**:
|
||||
- `backend/app/services/qr_login_service.py` (v5 修正版)
|
||||

|
||||
|
||||
## ⚡ 抖音文本策略优化 (18:10)
|
||||
|
||||
**问题**:
|
||||
- 抖音页面也是动态渲染的，"扫码登录" 文字出现有延迟。
|
||||
- 之前的 `get_by_text(...).count()` 是瞬间检查，如果页面还没加载完文字，直接返回 0 (失败)。
|
||||
- 结果：CSS 还在等，文本策略瞬间报空，导致最终还是没找到。
|
||||
|
||||
**优化方案**:
|
||||
1. **智能等待**: 对每个关键词 (如 "使用手机抖音扫码") 增加 `wait_for(timeout=2000)`，给页面一点加载时间。
|
||||
2. **扩大搜索圈**: 找到文字后，向父级查找 **5层** (之前是3层)，以适应抖音复杂的 DOM 结构。
|
||||
3. **尺寸过滤**: 增加 `width > 100` 判断，防止误匹配到头像或小图标。
|
||||
|
||||
**修改文件**:
|
||||
- `backend/app/services/qr_login_service.py` (v6 抖音增强版)
|
||||
|
||||
**状态**: ✅ 抖音策略已强化

**用户反馈**:
|
||||
- B站：成功获取 Cookie 并显示"已登录"状态。
|
||||
- 抖音：成功获取 Cookie 并显示"已登录"状态。
|
||||
- **结论**:
|
||||
1. 并行策略 (`asyncio.wait`) 有效解决了等待延迟。
|
||||
2. 文本锚点定位 (`get_by_text`) 有效解决了动态页面元素查找问题。
|
||||
3. 生命周期重构 (`manual start/close`) 解决了后台任务闪退问题。
|
||||
|
||||
**下一步**:
|
||||
- 进行实际视频发布测试。

## 🔍 更新前检查清单
|
||||
|
||||
> **核心原则**：追加前先查找，避免重复和遗漏
|
||||
|
||||
### 必须执行的检查步骤
|
||||
|
||||
**1. 快速浏览全文**（使用 `view_file` 或 `grep_search`）
|
||||
```markdown
|
||||
# 检查是否存在：
|
||||
- 同主题的旧章节？
|
||||
- 待更新的状态标记（🔄 待验证）？
|
||||
- 未完成的TODO项？
|
||||
```
|
||||
|
||||
**2. 判断操作类型**
|
||||
|
||||
| 情况 | 操作 |
|
||||
|------|------|
|
||||
| **有相关旧内容且错误** | 替换（场景1） |
|
||||
| **有相关旧内容可改进** | 追加V2（场景2） |
|
||||
| **有待验证状态** | 更新状态标记 |
|
||||
| **全新独立内容** | 追加到末尾 |
|
||||
|
||||
**3. 必须更新的内容**
|
||||
|
||||
- ✅ **状态标记**：`🔄 待验证` → `✅ 已修复` / `❌ 失败`
|
||||
- ✅ **进度百分比**：更新为最新值
|
||||
- ✅ **文件修改列表**：补充新修改的文件
|
||||
- ❌ **禁止**：创建重复的章节标题
|
||||
|
||||
### 示例场景
|
||||
|
||||
**错误示例**（未检查旧内容）：
|
||||
```markdown
|
||||
## 🔧 QR登录修复 (15:00)
|
||||
**状态**：🔄 待验证
|
||||
|
||||
## 🔧 QR登录修复 (16:00) ❌ 重复！
|
||||
**状态**：✅ 已修复
|
||||
```
|
||||
|
||||
**正确做法**：
|
||||
```markdown
|
||||
## 🔧 QR登录修复 (15:00)
|
||||
**状态**：✅ 已修复 ← 直接更新原状态
|
||||
```

|
||||
|
||||
## <20>️ 工具使用规范
|
||||
|
||||
> **核心原则**：使用正确的工具，避免字符编码问题
|
||||
|
||||
### ✅ 推荐工具：replace_file_content
|
||||
|
||||
**使用场景**：
|
||||
- 追加新章节到文件末尾
|
||||
- 修改/替换现有章节内容
|
||||
- 更新状态标记（🔄 → ✅）
|
||||
- 修正错误内容
|
||||
|
||||
**优势**：
|
||||
- ✅ 自动处理字符编码（Windows CRLF）
|
||||
- ✅ 精确替换，不会误删其他内容
|
||||
- ✅ 有错误提示，方便调试
|
||||
|
||||
**注意事项**：
|
||||
```markdown
|
||||
1. **必须精确匹配**：TargetContent 必须与文件完全一致
|
||||
2. **处理换行符**：文件使用 \r\n，不要漏掉 \r
|
||||
3. **合理范围**：StartLine/EndLine 应覆盖目标内容
|
||||
4. **先读后写**：编辑前先 view_file 确认内容
|
||||
```
|
||||
|
||||
### ❌ 禁止使用：命令行工具
|
||||
|
||||
**禁止场景**：
|
||||
- ❌ 使用 `echo >>` 追加内容（编码问题）
|
||||
- ❌ 使用 PowerShell 直接修改文档（破坏格式）
|
||||
- ❌ 使用 sed/awk 等命令行工具
|
||||
|
||||
**原因**：
|
||||
- 容易破坏 UTF-8 编码
|
||||
- Windows CRLF vs Unix LF 混乱
|
||||
- 难以追踪修改，容易出错
|
||||
|
||||
**唯一例外**：简单的全局文本替换（如批量更新日期），且必须使用 `-NoNewline` 参数
|
||||
|
||||
### 📝 最佳实践示例
|
||||
|
||||
**追加新章节**：
|
||||
```python
|
||||
replace_file_content(
|
||||
TargetFile="path/to/DayN.md",
|
||||
TargetContent="## 🔗 相关文档\n\n...\n\n", # 文件末尾的内容
|
||||
ReplacementContent="## 🔗 相关文档\n\n...\n\n---\n\n## 🆕 新章节\n内容...",
|
||||
StartLine=280,
|
||||
EndLine=284
|
||||
)
|
||||
```
|
||||
|
||||
**修改现有内容**：
|
||||
```python
|
||||
replace_file_content(
|
||||
TargetContent="**状态**：🔄 待修复",
|
||||
ReplacementContent="**状态**：✅ 已修复",
|
||||
StartLine=310,
|
||||
EndLine=310
|
||||
)

每次更新 `task_complete.md` 时，必须**逐一检查**以下所有板块：
|
||||
|
||||
1. 查看 `task_complete.md` → 了解整体进度
|
||||
2. 查看最新 `DayN.md` → 确认今天是第几天

||||
- [ ] `整体进度`：简述当前状态
|
||||
- [ ] `快速导航`：Day 范围与文档一致
|
||||
|
||||
2. **核心任务区**
|
||||
- [ ] `已完成任务`：添加新的 [x] 项目
|
||||
- [ ] `后续规划`：管理三色板块 (优先/债务/未来)
|
||||
|
||||
3. **统计与回顾**
|
||||
- [ ] `进度统计`：更新对应模块状态和百分比
|
||||
- [ ] `里程碑`：若有重大进展，追加 `## Milestone N`
|
||||
|
||||
4. **底部链接**
|
||||
- [ ] `时间线`：追加今日概括
|
||||
- [ ] `相关文档`：更新 DayLog 链接范围
|
||||

|
||||
|
||||
We introduce `MuseTalk`, a **real-time high quality** lip-syncing model (30fps+ on an NVIDIA Tesla V100). MuseTalk can be applied with input videos, e.g., generated by [MuseV](https://github.com/TMElyralab/MuseV), as a complete virtual human solution.
|
||||
|
||||
## 🔥 Updates
|
||||
We're excited to unveil MuseTalk 1.5.
|
||||
This version **(1)** integrates training with perceptual loss, GAN loss, and sync loss, significantly boosting its overall performance. **(2)** We've implemented a two-stage training strategy and a spatio-temporal data sampling approach to strike a balance between visual quality and lip-sync accuracy.
|
||||
Learn more details [here](https://arxiv.org/abs/2410.10122).
|
||||
**The inference codes, training codes and model weights of MuseTalk 1.5 are all available now!** 🚀
|
||||
|
||||
# Overview
|
||||
`MuseTalk` is a real-time high quality audio-driven lip-syncing model trained in the latent space of `ft-mse-vae`, which
|
||||
|
||||
1. modifies an unseen face according to the input audio, with a size of face region of `256 x 256`.
|
||||
1. supports audio in various languages, such as Chinese, English, and Japanese.
|
||||
1. supports real-time inference with 30fps+ on an NVIDIA Tesla V100.
|
||||
1. supports modification of the center point of the face region proposes, which **SIGNIFICANTLY** affects generation results.
|
||||
1. checkpoint available trained on the HDTF and private dataset.

# News
|
||||
- [04/05/2025] :mega: We are excited to announce that the training code is now open-sourced! You can now train your own MuseTalk model using our provided training scripts and configurations.
|
||||
- [03/28/2025] We are thrilled to announce the release of our 1.5 version. This version is a significant improvement over the 1.0 version, with enhanced clarity, identity consistency, and precise lip-speech synchronization. We update the [technical report](https://arxiv.org/abs/2410.10122) with more details.
|
||||
- [10/18/2024] We release the [technical report](https://arxiv.org/abs/2410.10122v2). Our report details a superior model to the open-source L1 loss version. It includes GAN and perceptual losses for improved clarity, and sync loss for enhanced performance.
|
||||
- [04/17/2024] We release a pipeline that utilizes MuseTalk for real-time inference.
|
||||
- [04/16/2024] Release Gradio [demo](https://huggingface.co/spaces/TMElyralab/MuseTalk) on HuggingFace Spaces (thanks to HF team for their community grant)
|
||||
- [04/02/2024] Release MuseTalk project and pretrained models.
|
||||
|
||||
|
||||
## Model
|
||||
|
||||
MuseTalk was trained in latent spaces, where the images were encoded by a freezed VAE. The audio was encoded by a freezed `whisper-tiny` model. The architecture of the generation network was borrowed from the UNet of the `stable-diffusion-v1-4`, where the audio embeddings were fused to the image embeddings by cross-attention.
|
||||
|
||||
Note that although we use a very similar architecture as Stable Diffusion, MuseTalk is distinct in that it is **NOT** a diffusion model. Instead, MuseTalk operates by inpainting in the latent space with a single step.

### Setup FFmpeg
|
||||
1. [Download](https://github.com/BtbN/FFmpeg-Builds/releases) the ffmpeg-static package
|
||||
|
||||
2. Configure FFmpeg based on your operating system:
|
||||
|
||||
For Linux:
|
||||
```bash
|
||||
export FFMPEG_PATH=/path/to/ffmpeg
|
||||
# Example:
|
||||
export FFMPEG_PATH=/musetalk/ffmpeg-4.4-amd64-static
|
||||
```
|
||||
|
||||
For Windows:
|
||||
Add the `ffmpeg-xxx\bin` directory to your system's PATH environment variable. Verify the installation by running `ffmpeg -version` in the command prompt - it should display the ffmpeg version information.
|
||||
|
||||
### Download weights
|
||||
You can download weights in two ways:
|
||||
|
||||
#### Option 1: Using Download Scripts
|
||||
We provide two scripts for automatic downloading:
|
||||
|
||||
For Linux:
|
||||
```bash
|
||||
sh ./download_weights.sh
|
||||
```
|
||||
|
||||
For Windows:
|
||||
```batch
|
||||
# Run the script
|
||||
download_weights.bat
|
||||
```
|
||||
|
||||
#### Option 2: Manual Download
|
||||
You can also download the weights manually from the following links:
|
||||
|
||||
1. Download our trained [weights](https://huggingface.co/TMElyralab/MuseTalk/tree/main)
|
||||
2. Download the weights of other components:
|
||||
- [sd-vae-ft-mse](https://huggingface.co/stabilityai/sd-vae-ft-mse/tree/main)
|
||||
- [whisper](https://huggingface.co/openai/whisper-tiny/tree/main)
|
||||
- [dwpose](https://huggingface.co/yzd-v/DWPose/tree/main)
|
||||
- [syncnet](https://huggingface.co/ByteDance/LatentSync/tree/main)
|
||||
- [face-parse-bisent](https://drive.google.com/file/d/154JgKpzCPW82qINcVieuPH3fZ2e0P812/view?pli=1)
|
||||
- [resnet18](https://download.pytorch.org/models/resnet18-5c106cde.pth)
|
||||
|
||||
Finally, these weights should be organized in `models` as follows:
|
||||
```
|
||||

## Quickstart
|
||||
|
||||
### Inference
|
||||
We provide inference scripts for both versions of MuseTalk:
|
||||
|
||||
#### Prerequisites
|
||||
Before running inference, please ensure ffmpeg is installed and accessible:
|
||||
```bash
|
||||
# Check ffmpeg installation
|
||||
ffmpeg -version
|
||||
```
|
||||
If ffmpeg is not found, please install it first:
|
||||
- Windows: Download from [ffmpeg-static](https://github.com/BtbN/FFmpeg-Builds/releases) and add to PATH
|
||||
- Linux: `sudo apt-get install ffmpeg`
|
||||
|
||||
#### Normal Inference
|
||||
##### Linux Environment
|
||||
```bash
|
||||
# MuseTalk 1.5 (Recommended)
|
||||
sh inference.sh v1.5 normal
|
||||
|
||||
# MuseTalk 1.0
|
||||
sh inference.sh v1.0 normal
|
||||
```
|
||||
|
||||
##### Windows Environment
|
||||
|
||||
Please ensure that you set the `ffmpeg_path` to match the actual location of your FFmpeg installation.
|
||||
|
||||
```bash
|
||||
# MuseTalk 1.5 (Recommended)
|
||||
python -m scripts.inference --inference_config configs\inference\test.yaml --result_dir results\test --unet_model_path models\musetalkV15\unet.pth --unet_config models\musetalkV15\musetalk.json --version v15 --ffmpeg_path ffmpeg-master-latest-win64-gpl-shared\bin
|
||||
|
||||
# For MuseTalk 1.0, change:
|
||||
# - models\musetalkV15 -> models\musetalk
|
||||
# - unet.pth -> pytorch_model.bin
|
||||
# - --version v15 -> --version v1
|
||||
```
|
||||
|
||||
#### Real-time Inference
|
||||
##### Linux Environment
|
||||
```bash
|
||||

# For MuseTalk 1.0, change:
|

# - models\musetalkV15 -> models\musetalk
|

# - unet.pth -> pytorch_model.bin
|
||||
# - --version v15 -> --version v1
|
||||
```
|
||||
|
||||
The configuration file `configs/inference/test.yaml` contains the inference settings, including:
|
||||
- `video_path`: Path to the input video, image file, or directory of images
|
||||
- `audio_path`: Path to the input audio file
|
||||
|
||||
Note: For optimal results, we recommend using input videos with 25fps, which is the same fps used during model training. If your video has a lower frame rate, you can use frame interpolation or convert it to 25fps using ffmpeg.
|
||||
|
||||
Important notes for real-time inference:
|
||||
1. Set `preparation` to `True` when processing a new avatar
|
||||
2. After preparation, the avatar will generate videos using audio clips from `audio_clips`
|
||||
3. The generation process can achieve 30fps+ on an NVIDIA Tesla V100
|
||||
4. Set `preparation` to `False` for generating more videos with the same avatar
|
||||
|
||||
For faster generation without saving images, you can use:
|
||||
```bash
|
||||
python -m scripts.realtime_inference --inference_config configs/inference/realtime.yaml --skip_save_images
|
||||
```
|
||||
|
||||
## Gradio Demo
|
||||
We provide an intuitive web interface through Gradio for users to easily adjust input parameters. To optimize inference time, users can generate only the **first frame** to fine-tune the best lip-sync parameters, which helps reduce facial artifacts in the final output.
|
||||
|
||||
For minimum hardware requirements, we tested the system on a Windows environment using an NVIDIA GeForce RTX 3050 Ti Laptop GPU with 4GB VRAM. In fp16 mode, generating an 8-second video takes approximately 5 minutes. 
|
||||
|
||||
Both Linux and Windows users can launch the demo using the following command. Please ensure that the `ffmpeg_path` parameter matches your actual FFmpeg installation path:
|
||||
|
||||
```bash
|
||||
# You can remove --use_float16 for better quality, but it will increase VRAM usage and inference time
|
||||
python app.py --use_float16 --ffmpeg_path ffmpeg-master-latest-win64-gpl-shared\bin
|
||||
```
|
||||
|
||||
## Training
|
||||
|
||||
### Data Preparation
|
||||
To train MuseTalk, you need to prepare your dataset following these steps:
|
||||
|
||||
1. **Place your source videos**
|
||||
|
||||
For example, if you're using the HDTF dataset, place all your video files in `./dataset/HDTF/source`.
|
||||
|
||||
2. **Run the preprocessing script**
|
||||
```bash
|
||||
python -m scripts.preprocess --config ./configs/training/preprocess.yaml
|
||||
```
|
||||
This script will:
|
||||
- Extract frames from videos
|
||||
- Detect and align faces
|
||||
- Generate audio features
|
||||
- Create the necessary data structure for training
|
||||
|
||||
### Training Process
|
||||
After data preprocessing, you can start the training process:
|
||||
|
||||
1. **First Stage**
|
||||
```bash
|
||||
sh train.sh stage1
|
||||
```
|
||||
|
||||
2. **Second Stage**
|
||||
```bash
|
||||
sh train.sh stage2
|
||||
```
|
||||
|
||||
### Configuration Adjustment
|
||||
Before starting the training, you should adjust the configuration files according to your hardware and requirements:
|
||||
|
||||
1. **GPU Configuration** (`configs/training/gpu.yaml`):
|
||||
- `gpu_ids`: Specify the GPU IDs you want to use (e.g., "0,1,2,3")
|
||||
- `num_processes`: Set this to match the number of GPUs you're using
|
||||
|
||||
2. **Stage 1 Configuration** (`configs/training/stage1.yaml`):
|
||||
- `data.train_bs`: Adjust batch size based on your GPU memory (default: 32)
|
||||
- `data.n_sample_frames`: Number of sampled frames per video (default: 1)
|
||||
|
||||
3. **Stage 2 Configuration** (`configs/training/stage2.yaml`):
|
||||
- `random_init_unet`: Must be set to `False` to use the model from stage 1
|
||||
- `data.train_bs`: Smaller batch size due to high GPU memory cost (default: 2)
|
||||
- `data.n_sample_frames`: Higher value for temporal consistency (default: 16)
|
||||
- `solver.gradient_accumulation_steps`: Increase to simulate larger batch sizes (default: 8)
|
||||
|
||||
|
||||
### GPU Memory Requirements
|
||||
Based on our testing on a machine with 8 NVIDIA H20 GPUs:
|
||||
|
||||

#### Use of bbox_shift to have adjustable results(For 1.0)
|
||||
:mag_right: We have found that upper-bound of the mask has an important impact on mouth openness. Thus, to control the mask region, we suggest using the `bbox_shift` parameter. Positive values (moving towards the lower half) increase mouth openness, while negative values (moving towards the upper half) decrease mouth openness.
|
||||
|
||||
You can start by running with the default configuration to obtain the adjustable value range, and then re-run the script within this range.
|
||||
|
||||
For example, in the case of `Xinying Sun`, after running the default configuration, it shows that the adjustable value rage is [-9, 9]. Then, to decrease the mouth openness, we set the value to be `-7`.
|
||||
```
|
||||
python -m scripts.inference --inference_config configs/inference/test.yaml --bbox_shift -7
|
||||
```
|
||||
:pushpin: More technical details can be found in [bbox_shift](assets/BBOX_SHIFT.md).
|
||||
|
||||
|
||||
#### Combining MuseV and MuseTalk
|
||||
|
||||
As a complete solution to virtual human generation, you are suggested to first apply [MuseV](https://github.com/TMElyralab/MuseV) to generate a video (text-to-video, image-to-video or pose-to-video) by referring [this](https://github.com/TMElyralab/MuseV?tab=readme-ov-file#text2video). Frame interpolation is suggested to increase frame rate. Then, you can use `MuseTalk` to generate a lip-sync video by referring [this](https://github.com/TMElyralab/MuseTalk?tab=readme-ov-file#inference).
|
||||
|
||||

1. MuseTalk has been built on [HDTF](https://github.com/MRzzm/HDTF) datasets.
|
||||
|
||||
Thanks for open-sourcing!
|
||||
|
||||
# Limitations
|
||||
- Resolution: Though MuseTalk uses a face region size of 256 x 256, which make it better than other open-source methods, it has not yet reached the theoretical resolution bound. We will continue to deal with this problem.
|
||||
If you need higher resolution, you could apply super resolution models such as [GFPGAN](https://github.com/TencentARC/GFPGAN) in combination with MuseTalk.
|
||||
|
||||
- Identity preservation: Some details of the original face are not well preserved, such as mustache, lip shape and color.
|
||||
|
||||
- Jitter: There exists some jitter as the current pipeline adopts single-frame generation.

This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
|
||||
# ViGent2 Frontend
|
||||
|
||||
## Getting Started
|
||||
ViGent2 的前端界面，采用 Next.js 14 + TailwindCSS 构建。
|
||||
|
||||
First, run the development server:
|
||||
## ✨ 核心功能
|
||||
|
||||
### 1. 视频生成 (`/`)
|
||||
- **素材管理**: 拖拽上传人物视频，实时预览。
|
||||
- **文案配音**: 集成 EdgeTTS，支持多音色选择 (云溪 / 晓晓)。
|
||||
- **进度追踪**: 实时显示视频生成进度 (10% -> 100%)。
|
||||
- **结果预览**: 生成完成后直接播放下载。
|
||||
|
||||
### 2. 全自动发布 (`/publish`) [Day 7 新增]
|
||||
- **多平台管理**: 统一管理 B站、抖音、小红书账号状态。
|
||||
- **扫码登录**:
|
||||
- 集成后端 Playwright 生成的 QR Code。
|
||||
- 实时检测扫码状态 (Wait/Success)。
|
||||
- Cookie 自动保存与状态同步。
|
||||
- **发布配置**: 设置视频标题、标签、简介。
|
||||
- **定时任务**: 支持 "立即发布" 或 "定时发布"。
|
||||
|
||||
## 🛠️ 技术栈
|
||||
|
||||
- **框架**: Next.js 14 (App Router)
|
||||
- **样式**: TailwindCSS
|
||||
- **图标**: Lucide React
|
||||
- **组件**: 自定义现代化组件 (Glassmorphism 风格)
|
||||
- **API**: Fetch API (对接后端 FastAPI :8006)
|
||||
|
||||
## 🚀 开发指南
|
||||
|
||||
### 安装依赖
|
||||
|
||||
```bash
|
||||
npm install
|
||||
```
|
||||
|
||||
### 启动开发服务器
|
||||
|
||||
默认运行在 **3002** 端口 (通过 `package.json` 配置):
|
||||
|
||||
```bash
|
||||
npm run dev
|
||||
# or
|
||||
yarn dev
|
||||
# or
|
||||
pnpm dev
|
||||
# or
|
||||
bun dev
|
||||
# 访问: http://localhost:3002
|
||||
```
|
||||
|
||||
Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
|
||||
### 目录结构
|
||||
|
||||
You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
|
||||
```
|
||||

|
||||
├── app/
|
||||
│ ├── page.tsx # 视频生成主页
|
||||

|
||||
│ └── layout.tsx # 全局布局 (导航栏)

|
||||
```
|
||||
|
||||

## 步骤 7: 性能优化 (预加载模型服务)
|
||||
|
||||
为了消除每次生成视频时 30-40秒 的模型加载时间，建议运行常驻服务。
|
||||
|
||||
### 1. 安装服务依赖
|
||||
|
||||
```bash
|
||||
conda activate latentsync
|
||||
pip install fastapi uvicorn
|
||||
```
|
||||
|
||||
### 2. 启动服务
|
||||
|
||||
**前台运行 (测试)**:
|
||||
```bash
|
||||
cd /home/rongye/ProgramFiles/ViGent2/models/LatentSync
|
||||
# 启动服务 (端口 8007) - 会自动读取 backend/.env 中的 GPU 配置
|
||||
python -m scripts.server
|
||||
```
|
||||
|
||||
**后台运行 (推荐)**:
|
||||
```bash
|
||||
nohup python -m scripts.server > server.log 2>&1 &
|
||||
```
|
||||
|
||||
### 3. 更新配置
|
||||
|
||||
修改 `ViGent2/backend/.env`:
|
||||
|
||||
```bash
|
||||
LATENTSYNC_USE_SERVER=True
|
||||
```
|
||||
|
||||
现在，后端通过 API 调用本地常驻服务，生成速度将显著提升。

Desired output channel layout of the audio. `True` is mono layout. `False` is unchanged.
