 ## Changelog
 
+### v1.3.5 (2026.5.31)
+
+**Hardware encoding expansion (H.264 / AV1) & multi-tenant license hardening & FRP sub-master automation**
+
+**New features:**
+- **Client hardware encoding**: new `CFFmpegH264Encoder` / `CFFmpegAV1Encoder` on the FFmpeg path, driving NVENC / Quick Sync / AMF GPU encoders; `EncoderFactory` picks the best available encoder at runtime
+- **Skip-encode on identical frames**: capture layer compares consecutive frames and skips both encode and transmit when the picture is static — hardware encoders no longer get fed duplicate frames during idle desktops
+- **Menu-driven compress / extract**: custom file + folder picker (`ZstaPickerDlg`) lets you select a mixed directory tree on the remote host to zip up, or extract an archive to a target path
+- **Auto-launch frp client for sub-masters**: when upstream issues a V2 license, frp config is shipped alongside it; the sub-master connects to the relay automatically with no manual `frpc.toml`
+- **Compliance-tailorable build**: `DISABLE_X264` / `DISABLE_FFMPEG` build flags produce binaries with zero x264 / FFmpeg dependency without touching source; paired with `LICENSE-THIRD-PARTY.txt`
+
+**Improvements:**
+- **Multi-tenant license server hardening**: `licenses.ini` hot path now has a recursive mutex + 30s throttle; write rate dropped from 0.6 → 0.07/sec (extrapolated to 100 online targets: ~160 → ~3.3 writes/sec). Closes the read-modify-write race that caused "preset renewal quota silently disappears"
+- **`licenses.ini` IP list 4KB truncation fix**: segmented writes prevent the tail of large IP histories from being silently dropped by `WritePrivateProfileString`'s 4KB single-value cap
+- **`BindType` enforced on SN import**: offline / online / trial SNs can no longer be cross-imported into the wrong bucket
+- **Client SCLoader slim-down**: removed `SCLoader.cpp` (10K lines of hard-coded stub); the client now uses the DLL delivered by the master at runtime
+- **Client logger graceful shutdown**: drains queued log lines on exit and records the exit signal — after a restart you still have the last 1-2 seconds of context
+- **IOCPClient early-packet guard**: packets that arrive before `setManagerCallBack` no longer trigger a null-callback crash (startup race)
+- **Multi-monitor trace-cursor position fix & MJPEG playback flip fix**: trace cursor coordinates corrected for cross-monitor capture; MJPEG upside-down playback fixed and 0-byte AVI residue removed on encoder-open failure
+- **FRP `privilegeKey` switched to UTC**: master / relay / client across different time zones no longer reject each other's frp auth because of local-time skew
+- **Linux client `install.sh` / `uninstall.sh`**: one-shot install / uninstall scripts, on par with macOS
+- **Go server build pipeline**: `build.ps1` / `build.cmd` now build the Go master as part of the main build
+- **Release / Download links migrated to Gitea**: v1.3.4+ is no longer published to GitHub
+
+**Bug fixes:**
+- Web file manager touch double-click unreliability: move threshold widened to avoid spurious drag detection, plus two sequential `click` events (20ms apart) instead of the non-standard `dblclick` — fixes folder rename / unresponsive clicks on Windows, Linux, and macOS
+- AUTH packet to sub-master used the wrong password generation path, causing sub-masters to fail authentication every time
+- Trial SN was being routed through the V2 / V1 license-issue branch

+### v1.3.5 (2026.5.31)
+
+**硬體編碼擴充（H.264 / AV1）& 多客戶授權生產化 & FRP 子級自動化**
+
+**新功能：**
+- **用戶端硬體編碼**：新增 FFmpeg 路徑的 `CFFmpegH264Encoder` / `CFFmpegAV1Encoder`，可呼叫 NVENC / Quick Sync / AMF 等 GPU 編碼器；`EncoderFactory` 執行時自動優選
+- **靜畫跳編碼**：擷取層比對前後影格，完全相同時跳過編碼與傳輸——硬體編碼器在靜畫時不再被強行餵入相同影格
+- **選單驅動的壓縮 / 解壓**：自訂檔案 + 資料夾選擇器（`ZstaPickerDlg`），可從遠端主機直接選混合目錄樹打包或解壓到目標路徑
+- **下級主控自動啟動 frp client**：上級簽發 V2 授權時一併下發 frp 設定，子級主控啟動即接通中繼鏈路，無需人工設定 `frpc.toml`
+- **合規可裁剪建置**：`DISABLE_X264` / `DISABLE_FFMPEG` 編譯開關，可在不動原始碼的前提下產出完全不含 x264 / FFmpeg 的二進位，搭配 `LICENSE-THIRD-PARTY.txt`
+
+**改進：**
+- **多客戶授權伺服端硬化**：`licenses.ini` hot-path 互斥鎖 + 30s 節流，寫入頻率從 0.6 → 0.07 次/秒（外推 100 在線：~160 → ~3.3 次/秒）；閉環「預設續期配額消失」的 read-modify-write 競態
+- **`licenses.ini` IP 清單 4KB 截斷修復**：分段寫入避免溢出尾部被永久丟棄
+- **匯入 SN 按 `BindType` 嚴格校驗**：避免離線版 / 連線版 / 試用版 SN 串庫
+- **用戶端 SCLoader 大瘦身**：移除一萬行硬編碼 stub（`SCLoader.cpp`），改用主控執行時下發 DLL 注入
+- **用戶端 logger 優雅退出**：程序結束時刷出佇列裡的日誌並記錄退出訊號
+- **IOCPClient 早期封包防護**：`setManagerCallBack` 之前抵達的封包不再觸發空回呼崩潰

+- **FRP `privilegeKey` 改用 UTC 時間戳**：跨時區主控 / 中繼 / 用戶端不再因本地時區讓 frp auth 失效
+- **Linux 用戶端 `install.sh` / `uninstall.sh`**：補齊一鍵部署 / 解除安裝指令稿

+# 视频编码硬件加速实现指导文档
+
+本文档供 AI 编码助手参考，用于在现有 C++ 远程控制程序中实现 H.264 硬件编码 + AV1 编码路径。
+
+---
+
+## 1. 项目背景
+
+### 1.1 当前状态
+
+- C++ Windows 远程控制程序
+- 已实现 H.264 编码，基于 x264 软编（`CX264Encoder`），preset = `ultrafast + zerolatency`
+- 视频管线：桌面捕获（RGB/BGRA）→ 编码 → 网络传输 → 客户端解码显示
+- 当前架构：每个主控端连接对应一个独立编码器实例
+- **分发模式**：单 exe，FFmpeg 静态链接
+
+### 1.2 目标
+
+分两阶段渐进推进，**始终保留 x264 软编作为兜底**：
+
+**阶段一（H.264 硬编加速）**
+- 新增 H.264 硬编（NVENC / QSV / AMF），按 GPU 能力探测优先走硬编
+- x264 软编在无 GPU / 虚拟机 / 远程桌面会话等环境下兜底
+- 浏览器解码零兼容性风险（H.264 全平台原生支持）
+
+**阶段二（AV1 路径）**
+- 新增 AV1 硬编（`av1_nvenc` / `av1_qsv` / `av1_amf`）
+- 客户端浏览器握手时声明 AV1 能力
+- 双方都能用就走 AV1，否则回落 H.264
+
+**最终产物仍为单 exe**，体积增量可接受 6–10 MB。
+
+### 1.3 关键决策记录
+
+#### 1.3.1 为什么跳过 HEVC
+
+经评估，HEVC 在本项目目标场景下没有独占价值：
+
+| 维度 | 现状 |
+|---|---|
+| **浏览器解码** | Firefox 完全不支持；Chrome/Edge 需 Win11 + 商店付费的 HEVC Video Extensions |
+| **专利授权** | 商用涉及 MPEG-LA / Access Advance / Velos Media 三个专利池 |
+| **替代方案** | AV1 压缩效率更高、AOMedia 免专利、浏览器原生支持广 |
+
+HEVC 编码端硬件普及度好（几乎所有 2015+ GPU）这个优势，被解码端短板完全抵消。
+
+#### 1.3.2 为什么 H.264 硬编先于 AV1
+
+- **AV1 硬编硬件门槛高**：仅 NVIDIA RTX 40+ / AMD RX 7000+ / Intel Arc 才有
+- **"多机混杂"场景**下大部分编码端 GPU 没有 AV1 硬编
+- **H.264 硬编**（NVENC/QSV/AMF）几乎所有现代 GPU 都有，覆盖面广
+- **客户端浏览器解 H.264** 是零兼容性问题，跨浏览器/跨平台 100% 通用
+
+H.264 硬编是先把"地板抬起来"，AV1 是"在新硬件上的天花板"。
+
+### 1.4 设计约束
+
+- **平台**：仅 Windows（macOS/Linux 未来另行设计）
+- **GPU 不确定**：NVIDIA / AMD / Intel / 无独显 / 虚拟机无 GPU 都需支持
+- **延迟要求**：不敏感（不追求极致低延迟）
+- **并发模型**：通常 1 对 1，少数 1 对多（每个连接独立编码器）
+- **客户端**：浏览器（WebCodecs 优先，`<video>` 次之），未来集成
+- **工具链**：Visual Studio 2019
+- **属性**：个人项目，暂不商用，专利问题搁置但仍优先选免专利方案
+

+
+### 2.2 编码器后端表
+
+| 类型 | FFmpeg 编码器名 | 硬件要求 | 备注 |
+|---|---|---|---|
+| AV1 硬编 | `av1_nvenc` | NVIDIA RTX 40+（Ada Lovelace） | 2022 Q4 起 |
+| AV1 硬编 | `av1_amf`   | AMD RX 7000+（RDNA 3） | 2022 Q4 起 |
+| AV1 硬编 | `av1_qsv`   | Intel Arc / 部分新 Iris Xe | 2022 起 |
+| H.264 硬编 | `h264_nvenc` | 几乎所有 NVIDIA GPU（GTX 650+） | 2012 起 |
+| H.264 硬编 | `h264_qsv`   | 几乎所有 Intel 核显（HD 4000+） | 2012 起 |
+| H.264 硬编 | `h264_amf`   | 几乎所有 AMD GPU | |
+| H.264 硬编 | `h264_mf`    | Windows Media Foundation | 兜底，质量/稳定性一般 |
+| H.264 软编 | `libx264`（现有 `CX264Encoder`） | 任意 CPU | 始终兜底 |
+
+**不使用 `libx265` / `libaom-av1` / `libsvtav1`**（CPU 软编），原因：
+- 远控产品对 CPU 占用敏感，AV1/HEVC 软编实时编码压力大
+- `libx265` 会让 FFmpeg 切到 GPL，`libaom-av1` 编码速度也不够
+
+### 2.3 类结构
+
+```
+VideoEncoderBase（新增抽象接口）
+    ├── CX264Encoder           （改造现有类继承接口，保留软编兜底）
+    ├── CFFmpegH264Encoder     （新增，封装 h264_nvenc/qsv/amf/mf）
+    └── CFFmpegAV1Encoder      （新增，封装 av1_nvenc/qsv/amf）
+```
+
+### 2.4 协商流程
+
+```
+握手阶段：
+- 客户端（浏览器）在 WebSocket 握手时上报能力：
+    { "codecs": ["av1", "h264"] }    // 浏览器实际能解的，按优先级排
+- 服务端取「客户端能力 ∩ 自己硬件能力」选 codec
+
+会话阶段：
+- 选定 codec 后创建对应编码器，整个连接生命周期不变
+- 运行中不切换 codec（保持简单，需要切换就重连）
+```

+## 3. 硬编 vs 现有 x264 软编对比
+
+### 3.1 CPU 占用（最大收益）
+
+| 编码器 | 1080p @ 30fps CPU 占用 |
+|---|---|
+| x264 `ultrafast`（现状） | 单核 15–30% |
+| x264 `medium`（同画质基准） | 单核 60–100% |
+| `h264_nvenc p4` | 总 **1–3%** |
+| `h264_qsv medium` | 总 2–5% |
+| `h264_amf balanced` | 总 2–5% |
+
+被控端是用户的主力工作机，他自己还在干活。CPU 让出来意味着远控对他几乎不可感。
+
+### 3.2 同 CPU 预算下画质更高
+
+x264 的 preset 排序（同码率下画质）：
+
+```
+ultrafast < superfast < veryfast < faster < fast < medium < slow ...
+   ↑ 现状                                       ↑ 标准基准
+```
+
+NVENC `p4` 预设大致对应 x264 `fast` ~ `medium`，**画质明显优于当前 ultrafast，且 CPU 占用低一个数量级**。
+
+### 3.3 其他收益
+
+- **编码延迟稳定**：ASIC 不受 CPU 调度影响，单帧 1–5 ms
+- **笔记本电池/温度**：ASIC 几瓦，键盘不烫、风扇不转
+- **可拉高分辨率/帧率**：4K@30 / 多屏拼接软编扛不住，硬编轻松
+
+### 3.4 代价（必须接受）
+
+- **二进制 +6–10 MB**（FFmpeg 静态库，可接受）
+- **编译复杂度上升**：vcpkg 或自编 FFmpeg
+- **不同后端参数语义有差异**：rc 模式、preset 名字、bitrate 表现都不一样
+- **必须保留 x264 软编兜底**：无 GPU / 远程桌面 / 虚拟机 / NVENC session 满 等场景
+
+---
+
+## 4. 现有 H.264 编码器现状
+
+`CX264Encoder` 签名（`client/X264Encoder.cpp`）：
+
+```cpp
+class CX264Encoder
+{
+private:
+    x264_t*         m_pCodec;
+    x264_picture_t* m_pPicIn;
+    x264_picture_t* m_pPicOut;
+    x264_param_t    m_Param;
+
+public:
+    bool open(int width, int height, int fps, int crf);
+    bool open(x264_param_t* param);
+    void close();
+    int encode(uint8_t* rgb, uint8_t bpp, uint32_t stride,
+               uint32_t width, uint32_t height,
+               uint8_t** lppData, uint32_t* lpSize,
+               int direction = 1);
+};
+```
+
+集成点（`client/ScreenCapture.h`）：
+
+| 位置 | 内容 |
+|---|---|
+| `L148` | `CX264Encoder* m_encoder;`（持有具体类，需改为接口） |
+| `L926-930` | 关键帧路径硬编码 `new CX264Encoder()` |
+| `L956-960` | 增量帧路径硬编码 `new CX264Encoder()` |
+| `L170-176` | `BitRateToCRF(bitRate)` 码率→CRF 映射 |
+
+参数现状：
+- `param.i_threads = 1`
+- `preset = "ultrafast", tune = "zerolatency"`
+- `i_keyint_max = fps * 15`（15 秒一个 IDR）
+- `i_bframe = 0`、`b_open_gop = 0`
+- `rc.i_rc_method = X264_RC_CRF`（CRF 模式，未设 VBV）
+
+需要的改造（详见 §6）：
+1. `ScreenCapture::m_encoder` 改 `std::unique_ptr<VideoEncoderBase>`
+2. 编码器创建走 `CreateEncoder` 工厂
+3. 接口的 quality 语义解耦（CRF vs kbps，详见 §6.2）
+
+---
+
+## 5. FFmpeg 静态库准备
+
+### 5.1 推荐方案：vcpkg
+
+VS2019 + vcpkg 是最稳的路径：
+
+```
+vcpkg install ffmpeg[core,nvcodec,amf,qsv]:x64-windows-static-md
+```
+
+要点：
+- **三元组选 `x64-windows-static-md`**：链接静态 FFmpeg 但用动态 CRT（`/MD`），与本项目当前工程一致
+- 如果工程是 `/MT` 改用 `x64-windows-static`
+- `nvcodec` feature 引入 NVENC 头文件，`amf` 引入 AMF，`qsv` 引入 libmfx
+- 阶段一只需要 H.264，可以先不带这些 feature，但建议一次到位
+
+阶段二需要 AV1，FFmpeg 较新版本默认已支持 `av1_nvenc` / `av1_amf` / `av1_qsv`，无需额外 feature 名。
+
+### 5.2 备选方案：自编
+
+MSYS2 + MinGW-w64 + `--toolchain=msvc` 产出 MSVC 兼容 `.lib`：
+
+```bash
+./configure \
+  --prefix=/path/to/install \
+  --arch=x86_64 \
+  --target-os=mingw64 \
+  --toolchain=msvc \
+  --disable-shared --enable-static \
+  --disable-everything \
+  --disable-autodetect \
+  --disable-network \
+  --disable-doc \
+  --disable-programs \
+  --disable-debug \
+  --enable-small \
+  --enable-encoder=h264_nvenc \
+  --enable-encoder=h264_amf \
+  --enable-encoder=h264_qsv \
+  --enable-encoder=h264_mf \
+  --enable-encoder=av1_nvenc \
+  --enable-encoder=av1_amf \
+  --enable-encoder=av1_qsv \
+  --enable-protocol=file
+```
+
+**不要** `--enable-gpl` 或 `--enable-libx265 / --enable-libaom`，保持 LGPL 且避免软编 H.265/AV1。
+
+### 5.3 工程链接配置（MSVC）
+
+**附加包含目录**（C/C++ → 常规）：
+```
+$(VcpkgRoot)\installed\x64-windows-static-md\include
+```
+
+**附加库目录**（链接器 → 常规）：
+```
+$(VcpkgRoot)\installed\x64-windows-static-md\lib
+```
+
+**附加依赖项**（链接器 → 输入）：
+```
+avcodec.lib
+avutil.lib
+swresample.lib
+
+# FFmpeg 静态链接依赖的 Windows 系统库
+mfplat.lib
+mfuuid.lib
+strmiids.lib
+ws2_32.lib
+secur32.lib
+bcrypt.lib
+```
+
+**预处理器定义**：
+```
+ENABLE_HW_ENCODER
+__STDC_CONSTANT_MACROS    # FFmpeg C 头文件在 C++ 中需要
+```

+
+## 6. 实现任务清单
+
+### 6.1 文件清单
+
+| 文件 | 操作 | 说明 |
+|---|---|---|
+| `VideoEncoderBase.h` | 新增 | 抽象基类 + EncoderParams |
+| `X264Encoder.h/.cpp` | 修改 | 继承 `VideoEncoderBase`，新增 `forceIDR()` / `codec()` / `backendName()` |
+| `CFFmpegH264Encoder.h/.cpp` | 新增（阶段一） | 封装 `h264_nvenc/qsv/amf/mf` |
+| `CFFmpegAV1Encoder.h/.cpp` | 新增（阶段二） | 封装 `av1_nvenc/qsv/amf` |
+| `EncoderFactory.h/.cpp` | 新增 | 工厂 + 多后端探测 |
+| `EncoderProbe.h/.cpp` | 新增 | 启动时一次性探测可用后端，缓存结果 |
+| `ScreenCapture.h` | 修改 | `m_encoder` 改 `std::unique_ptr<VideoEncoderBase>` |
+| 握手协议代码 | 修改（阶段二） | 加 `codecs` 能力字段 |
+| 工程配置 | 修改 | FFmpeg 静态库链接（详见 §5.3） |
+
+### 6.2 抽象接口定义
+
+`VideoEncoderBase.h`：
+
+```cpp
+#pragma once
+#include <cstdint>
+
+enum class VideoCodec { H264, AV1 };
+enum class RateControl { CRF, BITRATE };
+
+struct EncoderParams {
+    int width;
+    int height;
+    int fps;
+    RateControl rc = RateControl::BITRATE;
+    int crf = 23;            // 当 rc == CRF 时使用（x264 路径）
+    int bitrate_kbps = 4000; // 当 rc == BITRATE 时使用（硬编路径）
+    int gop_seconds = 4;     // 关键帧间隔（秒），编码器内部转 frames
+};
+
+class VideoEncoderBase {
+public:
+    virtual ~VideoEncoderBase() = default;
+
+    virtual bool open(const EncoderParams& params) = 0;
+    virtual void close() = 0;
+
+    virtual int encode(
+        uint8_t* rgb,
+        uint8_t  bpp,
+        uint32_t stride,
+        uint32_t width,
+        uint32_t height,
+        uint8_t** lppData,
+        uint32_t* lpSize,
+        int direction = 1
+    ) = 0;
+
+    virtual void forceIDR() = 0;
+    virtual void setBitrate(int kbps) {}   // 默认空实现
+    virtual VideoCodec codec() const = 0;
+    virtual const char* backendName() const = 0;  // "x264" / "h264_nvenc" / "av1_amf" ...
+};
+```
+
+设计要点：
+- **抛弃** `open(w, h, fps, quality)` 的设计 —— `quality` 在 H.264 是 CRF、在硬编是 kbps，语义不清楚是坑
+- 改用 `EncoderParams` 结构体 + `RateControl` 枚举，明确指定速率控制模式
+- `backendName()` 返回实际后端名（"x264" / "h264_nvenc" / "av1_amf"），调用方可用于日志/监控

+        width, height
+    );
+    return 0;
+}
+```
+
+### 6.4 CFFmpegAV1Encoder 设计
+
+结构与 `CFFmpegH264Encoder` **完全对称**，仅 backend 名换：
+
+```cpp
+static const char* kAV1Backends[] = {
+    "av1_nvenc",   // RTX 40+
+    "av1_amf",     // RX 7000+
+    "av1_qsv",     // Intel Arc / 部分 11 代+ 核显
+};
+```
+
+参数差异（av1_nvenc 与 h264_nvenc 略有不同）：
+
+```cpp
+if (strcmp(name, "av1_nvenc") == 0) {
+    av_opt_set(m_ctx->priv_data, "preset", "p4", 0);
+    av_opt_set(m_ctx->priv_data, "tune", "ll", 0);
+    av_opt_set(m_ctx->priv_data, "rc", "cbr", 0);
+    // AV1 特有：tile-columns/rows 可调，多核解码更友好
+    av_opt_set_int(m_ctx->priv_data, "tile-columns", 1, 0);
+} else if (strcmp(name, "av1_amf") == 0) {
+    av_opt_set(m_ctx->priv_data, "usage", "lowlatency", 0);
+    av_opt_set(m_ctx->priv_data, "quality", "balanced", 0);
+    av_opt_set(m_ctx->priv_data, "rc", "cbr", 0);
+} else if (strcmp(name, "av1_qsv") == 0) {
+    av_opt_set(m_ctx->priv_data, "preset", "medium", 0);
+    av_opt_set_int(m_ctx->priv_data, "async_depth", 1, 0);
+}
+```
+
+实现建议：先把 `CFFmpegH264Encoder` 跑通稳定，**再把它复制改名做 AV1 版本**。同步两个类的逻辑可以后续考虑抽公共基类，但不要为了 DRY 提前抽。
+
+### 6.5 EncoderFactory 与探测

+        }
+    }
+
+    LOG_ERROR("encoder: all backends failed");
+    return nullptr;
+}
+```
+
+要点：
+- **不要**引入会话池（`HEVCSessionPool` 那套）—— 个人项目场景下不需要
+- NVENC session 限制由 FFmpeg 自己报错，工厂捕获后自动降级
+- 失败路径都打日志，方便定位
+
+### 6.6 启动时一次性后端探测
+
+避免每个新连接都重复尝试每个 backend：
+
+```cpp
+// EncoderProbe.h
+class EncoderProbe {
+public:
+    static void RunOnce();                 // 程序启动时调用一次
+    static bool HasAV1Hw();
+    static bool HasH264Hw();
+    static const char* PreferredAV1Backend();   // 第一个能用的 AV1 后端名
+    static const char* PreferredH264Backend();
+};
+
+// EncoderProbe.cpp 实现思路：
+// 对每个候选后端尝试 alloc_context → open2 → free
+// 用最低分辨率（如 640x480 @30fps）减少探测开销
+// 结果缓存在静态变量，加 std::once_flag 保证线程安全
+```
+
+启动时探测 1 次，运行时 `CreateEncoder` 直接读结果。
+
+### 6.7 ScreenCapture.h 改造
+
+**当前**（`client/ScreenCapture.h:148, 926-930, 956-960`）：
+```cpp
+CX264Encoder* m_encoder;
+// ...
+m_encoder = new CX264Encoder();
+int br = (m_nBitRate > 0) ? m_nBitRate : (width * height / 1266);
+m_encoder->open(width, height, 20, BitRateToCRF(br));
+```
+
+**改造后**：
+```cpp
+std::unique_ptr<VideoEncoderBase> m_encoder;
+ClientCapability m_clientCap;   // 握手阶段填入
+// ...
+if (!m_encoder) {
+    EncoderRequest req{
+        (int)width, (int)height, 20,
+        m_nBitRate > 0 ? m_nBitRate : (int)(width * height / 1266),
+        m_clientCap
+    };
+    m_encoder = CreateEncoder(req);
+    if (!m_encoder) return nullptr;
+}
+int err = m_encoder->encode(nextData, 32, 4 * width, width, height,
+                            &encoded_data, &encoded_size);
+```
+
+注意：两处 `new CX264Encoder()` 提取成一个 `ensureEncoder()` 私有方法，避免重复。
+
+### 6.8 协议握手（阶段二）
+
+客户端浏览器 WebSocket 连接时上报：
+
+```json
+{
+  "type": "client_capability",
+  "codecs": ["av1", "h264"]
+}
+```
+
+浏览器端探测脚本（JS）：
+
+```javascript
+async function probeBrowserCodecs() {
+    const codecs = [];
+    if (typeof VideoDecoder !== 'undefined') {
+        // AV1 Main Profile, Level 4.0, 8-bit
+        const av1 = await VideoDecoder.isConfigSupported({ codec: 'av01.0.04M.08' });
+        if (av1.supported) codecs.push('av1');
+    }
+    codecs.push('h264');   // 兜底假定支持，<video> 标签也支持
+    return codecs;
+}
+```
+
+**向后兼容**：老版本客户端不发 `codecs` 字段 → 服务端按 H.264 处理。`ClientCapability::supportAV1` 默认 false。
+
+可参考 `docs/hevc_browser_decode_test.html`（改造一份 AV1 版本）做浏览器解码端到端验证。
+
+---
+
+## 7. 像素格式与转换
+
+保持与现有 x264 路径完全一致的做法：
+
+- **硬编内部格式**：`AV_PIX_FMT_NV12`（NVENC/QSV/AMF 通用）
+- **转换库**：libyuv（不引入 `sws_scale`）
+- **BGRA → NV12**：`libyuv::ARGBToNV12` 直接
+- **RGB24 → NV12**：libyuv 无直接 API，分两步 RGB24 → I420 → NV12
+- **direction 参数**：沿用现有 `X264Encoder.cpp:136` 的写法（`direction * height` 作为乘子）
+
+---
+
+## 8. 测试要求
+
+### 8.1 单元测试
+
+- `VideoEncoderBase` 各实现的 `open / encode / close` 生命周期
+- `CFFmpegH264Encoder` 在缺失各后端时降级到下一个
+- `EncoderFactory` 在不同 `ClientCapability` × 硬件能力 矩阵下返回正确后端
+- `EncoderProbe::RunOnce()` 在不同 GPU 上的结果一致性
+
+### 8.2 集成测试
+
+| 场景 | 期望 |
+|---|---|
+| 客户端支持 AV1 + 编码端 RTX 40 | 使用 AV1（`av1_nvenc`） |
+| 客户端支持 AV1 + 编码端 GTX 1080 | 降级 H.264 硬编（`h264_nvenc`） |
+| 客户端不支持 AV1 + 编码端任意 | H.264（硬编优先） |
+| 编码端无 GPU / 虚拟机 | x264 软编 |
+| 编码端集显 + 独显 | 优先级中第一个成功的后端 |
+| 中途客户端能力变化 | 当前连接不变；下次握手按新能力 |
+| H264 硬编创建失败 | 自动回落 x264 软编，连接不断 |
+
+### 8.3 硬件验证矩阵
+
+| 编码端 | 客户端浏览器 | 期望 |
+|---|---|---|
+| RTX 40 / 50 | Chrome / Firefox / Edge | AV1 |
+| GTX 10/16 / RTX 20/30 | Chrome / Firefox / Edge | H.264 NVENC |
+| Intel Arc | Chrome / Firefox | AV1（`av1_qsv`） |
+| Intel 12 代+ 核显 | Chrome / Firefox | H.264 QSV |
+| AMD RX 7000+ | Chrome / Firefox | AV1（`av1_amf`） |
+| AMD 老卡 | Chrome / Firefox | H.264 AMF |
+| 虚拟机 / 远程桌面会话 | 任意 | x264 软编 |
+| iOS Safari < 17 | 任意编码端 | H.264 |
+| iOS Safari ≥ 17（A17 Pro+） | 任意编码端 | AV1 优先 |
+
+### 8.4 体积验证
+
+- exe 体积增量 < 12 MB（vcpkg 静态链接，含 AV1+H264 全后端）
+- 若超出明显，检查 vcpkg feature 是否引入了不需要的 codec
+
+### 8.5 回归测试（关键）
+
+每一步改造后必须验证：
+- 现有 x264 软编通路完全可用（在禁用所有硬编后端的环境下）
+- 现有客户端（不发 `codecs` 字段）可正常工作
+- 编码码流向后兼容，老客户端能解
+
+---
+
+## 9. 已知风险与注意事项
+
+### 9.1 多 GPU 跨适配器
+笔记本集显+独显场景，FFmpeg 默认走主显卡。可能报 "failed to create device"。**Catch 后回落到下一个后端**，不要直接终止。
+
+### 9.2 第一帧延迟
+FFmpeg 硬编可能在首次 `send_frame` 后 `receive_packet` 返回 `EAGAIN`。调用方代码必须能处理 `*lpSize == 0` 的情况（返回 0 表示成功但本次无输出）。`ScreenCapture::GetNextScreenData` 当前 `encoded_size == 0` 会怎么处理需要确认。
+
+### 9.3 NVENC session 数限制
+NVIDIA **消费级**卡（GeForce）有 NVENC session 上限（驱动 522.25+ 起 3 个，更新版可能放宽到 5）。多连接超限时 `open` 失败 → 工厂自动降级到 QSV/AMF/x264。**不要做"会话池"提前拦截** —— 让 FFmpeg 自己报错，工厂处理。
+
+### 9.4 浏览器解 AV1 的硬件依赖
+- 桌面 Chrome/Firefox/Edge：软解兜底（CPU 占用高，但能用）
+- 移动端：iPhone 15 Pro+ / M3+ 才有 AV1 硬解，老设备只能软解（可能卡）
+- `isConfigSupported` 报 true 不等于跑得流畅。**建议握手时也带上设备类型**，弱设备强制走 H.264
+
+### 9.5 LGPL 静态链接合规
+个人项目暂搁置。商用前需法务确认（FFmpeg 源代码提供、重新链接能力等）。
+
+### 9.6 配置项（建议）
+
+建议做成 INI/JSON：
+```
+encoder.prefer_av1            = true
+encoder.h264.bitrate_default  = 4000   (kbps)
+encoder.fallback_to_x264      = true
+encoder.probe_at_startup      = true
+encoder.disable_h264_mf       = true   (h264_mf 质量一般，可禁用)
+```
+
+### 9.7 日志要求
+
+关键路径必须有日志：
+- 启动探测结果：每个后端是否可用 + 失败原因（`av_err2str`）
+- 每个连接选定的 `codec` + `backend`（INFO）
+- 后端打开失败 + 回落（WARN）
+- 编码过程中的异常（ERROR）
+
+### 9.8 线程安全
+- 每个编码器实例不跨线程
+- `EncoderProbe` 单例首次初始化加 `std::once_flag`
+- FFmpeg 新版本不需要全局初始化（`av_register_all` 已废弃）
+
+### 9.9 与现有 `DISABLE_X264_FOR_TEST` 编译开关协同
+项目已有 `DISABLE_X264_FOR_TEST` 宏（见 `X264Encoder.cpp:5`）和最近 `c0a632a` 提交"Compliance: Add building option to disable x264 and ffmpeg"。新代码须遵循同样的可禁用约定：
+- `ENABLE_HW_ENCODER` 关闭时整个 `CFFmpegH264Encoder` / `CFFmpegAV1Encoder` 编译为空实现或不参与链接
+- 工厂在该宏关闭时直接返回 `CX264Encoder`
+
+---
+
+## 10. 实现顺序建议
+
+**每一步独立可合入**，每一步完成后 x264 通路必须可用、客户端无感知。
+
+### Step 0：抽象层（零功能改动）
+1. 新建 `VideoEncoderBase.h`，定义接口 + `EncoderParams` + `RateControl`
+2. `CX264Encoder` 改造继承 `VideoEncoderBase`：
+   - 新增 `forceIDR()`（设置一个标志，下次 encode 时通过 `x264_picture_t::i_type = X264_TYPE_IDR`）
+   - 实现 `codec()` 返回 `H264`
+   - 实现 `backendName()` 返回 `"x264"`
+   - 旧 `open(w, h, fps, crf)` 签名保留，转调新的 `open(EncoderParams)`
+3. `ScreenCapture::m_encoder` 改 `std::unique_ptr<VideoEncoderBase>`，但仍直接 `new CX264Encoder`
+4. **不引 FFmpeg、不引工厂**
+5. 验证：H.264 通路完全不变，对外行为零变化
+
+### Step 1：FFmpeg 集成 + `h264_nvenc` 单后端
+1. vcpkg 安装 `ffmpeg[core,nvcodec]:x64-windows-static-md`
+2. 工程添加包含目录 / 库目录 / 系统库
+3. 新建 `CFFmpegH264Encoder`，仅实现 `h264_nvenc`
+4. 在 `ScreenCapture` 加临时开关：硬编码切到 `CFFmpegH264Encoder` 跑一下
+5. 用浏览器解码 demo 验证码流能解
+6. 体积验证（应 +4–6 MB）
+
+### Step 2：扩展 H.264 硬编后端
+1. `CFFmpegH264Encoder` 加 `h264_qsv` / `h264_amf` 探测
+2. 顺序：`nvenc → qsv → amf`（`mf` 可暂不接）
+3. 不同后端的参数适配（见 §6.3.2）
+4. 测试 Intel 核显 + AMD 卡
+
+### Step 3：工厂 + 软编兜底
+1. 新建 `EncoderFactory` / `EncoderProbe`
+2. 工厂按 `H264 硬编 → x264 软编` 顺序
+3. `ScreenCapture` 改用工厂（消除两处 `new CX264Encoder`）
+4. 测试无 GPU 环境降级到 x264
+
+### Step 4：AV1 路径（独立闭环）
+1. 重跑 vcpkg：`ffmpeg[core,nvcodec,amf,qsv]:x64-windows-static-md`
+2. 新建 `CFFmpegAV1Encoder`，结构与 H.264 对称（直接 copy + 改 backend 名 + 调参）
+3. `EncoderProbe` 加 AV1 探测
+4. 工厂前置 AV1 路径
+5. 硬件验证矩阵执行
+
+### Step 5：握手协商 + 浏览器探测
+1. 客户端 JS `isConfigSupported` 探测 AV1 / H.264
+2. WebSocket 握手字段 `codecs` 上报
+3. 服务端解析后填入 `ClientCapability`
+4. 老客户端向后兼容（无 `codecs` 字段 → 默认 H.264）
+5. 端到端验证：编码端 RTX 40 + 浏览器 Chrome 走 AV1，回落场景走 H.264
+
+---
+
+## 11. 不在本次范围
+
+- HEVC 编码（决策已排除，见 §1.3.1）
+- 软编 AV1（libaom / SVT-AV1，CPU 占用不适合远控）
+- 运行中动态切换 codec（需要切换就重连）
+- 转发流（1 路编码多路分发）
+- 桌面捕获共享
+- 客户端浏览器解码具体实现（可参考 `docs/hevc_browser_decode_test.html` 改 AV1 版本验证）
+- Linux/macOS 移植
+- FFmpeg DLL 形式分发
