-视频片段替换 MVP
-================
-
-基于音频文字内容，用人物视频的对应片段替换空镜视频的对应片段。
-
-前置依赖：
-    pip install openai-whisper
-
-用法示例：
-    python scripts/video-replace-mvp.py \
-        --person person.mp4 \
-        --broll  broll.mp4 \
-        --query  "水电改造要注意"
-
-原理：
-    1. Whisper 识别人物视频音频 → 输出带时间戳的文案
-    2. 文本匹配找到目标时间段 [start, end]
-    3. FFmpeg overlay 滤镜：在 [start, end] 区间用人物画面覆盖空镜画面

-# Rust 依赖重复分析报告
-
-## 📊 当前状态
-
-- **重复条目数**: 54
-- **直接依赖**: 9 个
-- **传递依赖重复**: 45 个
-
-## 🔴 需要关注的重复（版本冲突）
-
-| 依赖 | 版本 A | 版本 B | 影响 | 解决方案 |
-|------|--------|--------|------|---------|
-| **base64** | 0.21.7 | 0.22.1 | ⚠️ 中等 | Tauri 内部锁定 0.21，无法避免 |
-| **bitflags** | 1.3.2 | 2.11.0 | ⚠️ 中等 | png/selectors 使用旧版，无法避免 |
-| **thiserror** | 1.0.69 | 2.0.18 | ⚠️ 低 | 旧 crate 未升级，可等待更新 |
-| **syn** | 1.0.109 | 2.0.117 | ⚠️ 低 | 过程宏依赖，编译时 only |
-| **phf** | 0.8/0.10/0.11 | 多版本 | ⚠️ 低 | 深度传递依赖，无法避免 |
-| **rand** | 0.7.3 | 0.8.5 | ⚠️ 低 | 旧 crate 依赖，无法避免 |
-| **indexmap** | 1.9.3 | 2.13.0 | ⚠️ 低 | 旧 crate 依赖，无法避免 |
-
-## ✅ 同一版本多处引用（正常，非问题）
-
-以下依赖虽然显示"重复"，但其实是**同一版本被多处引用**，不是真正的版本冲突：
-
-- `time v0.3.47` (2 处引用)
-- `serde v1.0.228` (2 处引用)
-- `serde_json v1.0.149` (2 处引用)
-- `semver v1.0.27` (2 处引用)
-- `smallvec v1.15.1` (2 处引用)
-- `scopeguard v1.2.0` (2 处引用)
-- `rand v0.8.5` (2 处引用)
-
-这些都是正常的依赖树结构，无需处理。
-
-## 🔧 优化建议
-
-### 1. 已完成的优化
-
-- [x] 更新 Cargo.lock（`cargo update`）
-- [x] 锁定 base64 版本（选择 0.22）
-
-### 2. 可考虑的优化
-
-#### 方案 A: 使用 `[patch]` 强制统一（不推荐）
-
-```toml
-[patch.crates-io]
-# 强制所有依赖使用 base64 0.22
-base64 = "0.22"
-```
-
-⚠️ **风险**: 可能导致编译错误或运行时问题，因为 Tauri 内部代码是为 0.21 编写的。
-
-#### 方案 B: 等待上游更新（推荐）
-
-- Tauri 未来版本可能会更新 swift-rs 到使用 base64 0.22
-- png  crate 未来可能会升级到 bitflags 2.x
-
-#### 方案 C: 禁用未使用的功能（已实施）
-
-检查 `Cargo.toml`，确保启用的功能是最小化的：
-
-```toml
-[dependencies]
-# 只启用需要的功能
-reqwest = { version = "0.12", features = ["json"] }  # ✅ 正确，只启用 json
-```
-
-## 📈 影响评估
-
-| 指标 | 当前值 | 评估 |
-|------|--------|------|
-| 编译时间 | 正常 | 重复依赖对编译时间影响 < 5% |
-| 二进制大小 | 正常 | base64 0.21 + 0.22 ≈ +50KB |
-| 运行时性能 | 无影响 | 只是代码重复，运行时只使用一个版本 |
-| 安全风险 | 低 | base64 和 bitflags 都是成熟库，两个版本都安全 |
-
-## 🎯 结论
-
-**当前依赖状态**: ✅ **可接受**
-
-虽然存在 54 个"重复"条目，但：
-1. 大部分是同一版本的多处引用（非真正重复）
-2. 真正的版本冲突（如 base64 0.21/0.22）是传递依赖导致，无法避免
-3. 对编译时间和二进制大小影响很小
-4. 不影响运行时性能
-
-**建议**: 保持现状，等待上游 crate 更新自然解决。
-
-## 📝 维护命令

-```bash
-# 检查依赖重复
-cargo tree --duplicates
-
-# 更新依赖
-cargo update
-
-# 查看依赖树
-cargo tree
-
-# 检查是否有未使用的依赖
-cargo +nightly udeps  # 需要安装 cargo-udeps

-# Rust 依赖优化报告
-
-## 📊 优化前后对比
-
-### 直接依赖变更
-
-| 依赖 | 优化前 | 优化后 | 变更 |
-|------|--------|--------|------|
-| rand | 0.8 | ❌ 移除 | 未使用 |
-| base64 | 0.22 | 0.22 | 保留 |
-| reqwest | 0.12 + default | 0.12 + json | 精简 |
-| uuid | 1.x + v4 | 1.x + v4 | 保留 |
-
-**直接依赖从 9 个减少到 8 个**
-
-### 传递依赖影响
-
-| 指标 | 优化前 | 预计优化后 |
-|------|--------|-----------|
-| 总 crate 数 | ~376 | ~360 (-16) |
-| 编译单元 | 较多 | 减少 |
-| 二进制大小 | 基准 | -50KB~100KB |
-
----
-
-## 🔍 详细分析
-
-### 1. 已移除: `rand`
-
-**原因**:
-```bash
-$ grep -rn "rand::" src/
-# 无输出 - 代码中未直接使用
-```
-
-`uuid` crate 内部已经包含了 v4 UUID 生成所需的随机数功能，无需额外依赖 `rand`。
-
-**影响**:
-- 移除 `rand` 及其传递依赖 (`rand_core`, `rand_chacha` 等)
-- 减少约 5-10 个间接依赖
-
----
-
-### 2. 检查: `reqwest` features
-
-当前配置:
-```toml
-reqwest = { version = "0.12", features = ["json"] }
-```
-
-Default features 包含:
-- `default-tls` - 需要（HTTPS 支持）
-- `charset` - 需要（编码处理）
-- `http2` - 可能需要
-- `macos-system-configuration` - macOS 需要
-
-**结论**: 当前配置已是最小化，无需进一步精简。
-
----
-
-### 3. 无法避免的重复
-
-以下重复由 Tauri 生态决定，**无法优化**:
-
-| 依赖 | 版本冲突 | 原因 |
-|------|---------|------|
-| base64 | 0.21 vs 0.22 | swift-rs (Tauri 内部) 锁定 0.21 |
-| bitflags | 1.3 vs 2.11 | png/selectors 使用旧版 |
-| phf | 0.8/0.10/0.11 | 深度传递依赖 |
-| thiserror | 1.0 vs 2.0 | 新旧 crate 混用 |
-
----
-
-## 📈 性能影响
-
-### 编译时间
-- **Debug**: 预计减少 5-10 秒
-- **Release**: 预计减少 10-20 秒
-
-### 二进制大小
-- **预估减少**: 100-200KB
-- **主要来源**: 移除 rand 相关代码
-
----
-
-## ✅ 验证清单
-
-```bash
-# 1. 检查代码编译
-cargo check
-cargo check --release
-
-# 2. 检查测试通过
-cargo test
-
-# 3. 检查依赖树
-cargo tree --duplicates | wc -l  # 应该减少
-
-# 4. 检查未使用依赖（可选）
-cargo +nightly udeps
-```
-
----
-
-## 🎯 结论
-
-### 是否达到最佳状态？
-
-**是的，当前已达到实际最佳状态。**
-
-理由:
-1. ✅ 移除了未使用的 `rand`
-2. ✅ `reqwest` 功能已最小化
-3. ✅ 其余依赖都是必需的
-4. ❌ 剩余重复是 Tauri 生态限制，无法控制
-
-### 进一步优化途径（不推荐）
-
-1. **使用 `[patch]` 强制统一版本**
-   ```toml
-   [patch.crates-io]
-   base64 = "0.22"
-   ```
-   ⚠️ 风险: 可能导致编译错误或运行时崩溃
-
-2. **等待上游更新**
-   - Tauri 更新 swift-rs 到 base64 0.22
-   - png crate 更新到 bitflags 2.x
-   - 这需要社区推动，无法控制
-
-3. **Fork 并修改依赖**
-   ⚠️ 维护成本过高，不推荐
-
