-## 免責聲明
+## 本版本亮點：全平台閉環

-**請在使用本軟件前仔細閱讀以下聲明：**
+本專案長期以 **C++ MFC 主控**（`YAMA.exe`）為核心交付形態——經典 Gh0st 架構、IOCP 高效能核心、完整的遠端桌面 / 檔案 / 程序 / 媒體功能堆疊、多層授權體系、品牌客製化——**至今仍是主要使用的主控**。MFC 主控內建了基於 WebSocket 的 Web 遠端桌面服務，從 v1.3.1 起就已經支援**任意平台的瀏覽器**遠控被管裝置（手機 / 平板 / Linux / macOS 桌面均可）。

-1. **合法用途**：本專案僅供合法的技術研究、學習交流和授權的遠端管理使用。嚴禁將本軟件用於未經授權存取他人電腦系統、竊取資料、監控他人隱私等任何違法行為。
+本版本（v1.3.4）補上了最後一塊拼圖——**Go 主控**：一個**功能簡潔、聚焦於「遠端桌面 + 遠端終端 + 多使用者分級」** 的輕量伺服端，跨 Windows / Linux / macOS 編譯執行。它的定位**不是取代 MFC**，而是為那些**不方便執行 Windows VPS** 的使用者提供原生的 Linux / macOS 主控落腳點——例如純 Linux 伺服器、ARM Mac 長駐、嵌入式主控盒等情境。

-2. **使用者責任**：使用者必須遵守所在國家/地區的法律法規。因使用本軟件而產生的任何法律責任，由使用者自行承擔。
+### 兩種主控形態如何選擇

-3. **無擔保聲明**：本軟件按「現狀」提供，不附帶任何明示或暗示的擔保，包括但不限於適銷性、特定用途適用性的擔保。
+| 形態 | GUI | 功能覆蓋 | 平台 | 定位 |
+|---|---|---|---|---|
+| **C++ MFC 主控** (`YAMA.exe`) | 原生 Windows GUI + 內建 Web 服務 | ✅ **全部功能** | Windows | **主推方案**。日常運維、檔案管理、媒體擷取、多層授權、品牌客製化等都用它 |
+| **Go 主控**（新） | Web UI（任何瀏覽器） | 遠端桌面 + 遠端終端 + 多使用者 | Windows / Linux / macOS | **補充方案**。需要「零 Windows 依賴」的純 Linux / macOS 主控部署 |

-4. **免責條款**：開發者不對因使用、誤用或無法使用本軟件而造成的任何直接、間接、偶然、特殊或後果性損害承擔責任。
+> [!TIP]
+> 兩種主控**使用同一套用戶端**——可以混搭，例如一台 Windows MFC 主控 + 一台 Linux Go 主控並行管理同一批裝置群。

-5. **版權聲明**：本專案採用 MIT 協議開源，允許自由使用、修改和分發，但必須保留原始版權聲明。
+### Go 主控的核心能力（v1.3.4 新增）

-**繼續使用本軟件即表示您已閱讀、理解並同意上述所有條款。**
+- **遠端桌面**：H.264 流透過 WebSocket 直接推送瀏覽器，WebCodecs 硬體解碼，1080P @ 20fps 流暢
+- **遠端終端**：xterm.js + ConPTY/PTY，支援調整尺寸、Tab 自動補全
+- **多使用者體系**：管理員 / 一般使用者分級、Challenge-Response 登入、不透明 token、按裝置群授權
+- **生產部署**：Nginx 反向代理 + Let's Encrypt + Keyboard Lock + 全螢幕控制，防止 ESC / F11 誤退出
+- **刻意保持輕量**：不包含檔案管理、媒體擷取、登錄檔、服務管理等 MFC 主控專屬功能——這些請走 MFC 主控
+
+### 全平台支援矩陣
+
+|  | **用戶端 (受控端)** | **主控端** |
+|---|---|---|
+| **Windows** | ✅ 完整功能 | ✅ MFC `YAMA.exe`（推薦）/ Go |
+| **Linux** (X11) | ✅ 螢幕 + 終端 + 檔案 + 剪貼簿 | ✅ Go |
+| **macOS** (Intel + Apple Silicon) | ✅ 螢幕 + 終端 + 檔案 + 剪貼簿 | ✅ Go |

+### 內建技術措施
+
+原始碼層面構築多道獨立可驗證的反濫用屏障，詳見 [反濫用技術措施清單](./docs/Compliance_TechnicalMeasures.md)：
+
+- **入站連線 IP 區段校驗**：試用版若被部署到公網會觸發可見告警 latch
+- **監聽埠數量上限**：試用版限制 ≤ 2 個監聽埠，防多租戶中轉改造
+- **應用層 RTT 反代理**：LAN 內 RTT 閾值偵測，反向代理 / 隧道會被識別
+- **多層授權架構**：V2 ECDSA 離線 + V1 連線 + 試用版分級，每一層限制獨立
+- **Web 主控驗證**：強制 Challenge-Response 登入、登入限流、不透明 token、操作可稽核

+# YAMA 使用方法与技巧
+
+## 编译程序
+
+编译此程序需要Visual Studio 2019及以上版本。如果编译Go服务端，需要Go 1.25及以上版本。
+除了直接通过Visual Studio打开项目文件进行编译，也可以通过以下命令进行编译:
+
+- build.cmd: 编译YAMA.exe（自动提前编译客户端程序）
+- build.cmd publish：编译YAMA.exe且通过upx压缩，所生成的可执行文件较小。
+- buld.cmd server：只编译YAMA.exe，需保证所依赖的客户端程序已经编译。
+- build.cmd go-server：编译 Go 服务端，可以选择带publish 参数进行upx压缩。
+
+## Go 服务端
+
+支持在Windows、Linux、MacOS系统运行，使得用户不再依赖Windows服务器来搭建远程控制系统，且部署Go服务端在Linux或MacOS具有更高安全性。
+但是用户仍然需要有一台Windows电脑，使用YAMA生成客户端程序。
+
+## 生成客户端
+
+自版本v1.3.4起，不论是服务端/主控端，还是客户端/受管端，都支持在全平台运行（Windows、Linux、MacOS）。
+关于在生成客户端时怎么填参数，参考早期在 GitHub 的[文档](https://github.com/yuanyuanxiang/SimpleRemoter/wiki#生成参数)。
+此文档也许已经过时，但新文档没有准备好。因为生成客户端的逻辑没有改变，所以这篇文档仍然具有参考价值。
+
+## 更新内嵌资源
+
+参看 "server\2015Remote\BuildDlg.cpp" 描述，YAMA作为一个功能强大的远程管理系统，内嵌了包含客户端、开源工具在内的10多个资源。
+较新版本的YAMA支持在不修改源代码、不重新编译的情况下，更新内嵌的这些资源。用户只需要在当前YAMA进程的目录下，增加res子目录，
+将资源命名为如下所述的名称即可。例如编译了新版本的 frpc.dll， 将其放到 res/frps.dll 位置即可，重启YAMA即会使用该磁盘上的资源。
+
+```
+namespace ResFileName {
+    // Ghost 主程序
+    const char* GHOST_X86         = "ghost_x86.exe";
+    const char* GHOST_X64         = "ghost_x64.exe";
+    const char* GHOST_LINUX       = "ghost_linux";
+    const char* GHOST_MACOS       = "ghost_macos";
+    // TestRun 加载器
+    const char* TESTRUN_X86       = "testrun_x86.dll";
+    const char* TESTRUN_X64       = "testrun_x64.dll";
+    // ServerDll
+    const char* SERVERDLL_X86     = "serverdll_x86.dll";
+    const char* SERVERDLL_X64     = "serverdll_x64.dll";
+    // TinyRun
+    const char* TINYRUN_X86       = "tinyrun_x86.exe";
+    const char* TINYRUN_X64       = "tinyrun_x64.exe";
+    // SCLoader (Shellcode加载器)
+    const char* SCLOADER_X86      = "scloader_x86.bin";
+    const char* SCLOADER_X64      = "scloader_x64.bin";
+    const char* SCLOADER_X86_OLD  = "scloader_old_x86.bin";
+    const char* SCLOADER_X64_OLD  = "scloader_old_x64.bin";
+    // FRP 相关 (无架构区分，64位DLL)
+    const char* FRPC_DLL          = "frpc.dll";
+    const char* FRPS_DLL          = "frps.dll";
+    // 工具
+    const char* UPX_EXE           = "upx.exe";
+    const char* RCEDIT_EXE        = "rcedit.exe";
+}
+```
+
+## 使用插件
+
+将64位的Windows DLL放到Plugins目录，主控程序会加载DLL，且可以通过在线主机的右键菜单，将DLL发送的目标主机执行。
+开发自定义插件需要遵循一些规范：https://simpleremoter.com/plugins
+
+## 载荷分离
+
+通过设置 Web 端口（默认值8080），来开启Web远程桌面，且本机会提供文件下载服务。将文件放置于该目录，从外部访问链接即可下载。
+比如，生成服务端时，选择 Shellcode+AES, 开启文件下载，将载荷生成为单独的文件 "1.bin"，将此文件放置于Payloads 目录。
+访问 http://127.0.0.1:8080/payloads/1.bin 即可下载此载荷文件。如果本机具有公网IP，则127.0.0.1可替换为公网IP。在有公网IP的计算机开启Web功能，必须设置登录密码，否则存在安全风险。
+采用载荷分离方式生成的程序，只有7KB，运行此程序会下载载荷，解密载荷中的Shellcode并执行。加载器源代码见 client\SimpleSCLoader.c，采用了高级编程技巧，无导入函数。本项目不提供任何“面纱”保证，且使用场景只限技术研究和学习。
+
+## Web 远程桌面
+
+通过设置 Web 端口（默认值8080），即开启Web远程桌面，在浏览器地址栏访问本机8080端口就进入Web远程桌面，默认的密码是admin。
+如果本机有公网IP，务必修改默认密码，设置为较复杂的密码，否则可能被别人登录。Web登录已做防护，连续3次输入错误密码会冻结。
+从外部访问Web远程桌面，需要域名和证书（浏览器H264解码硬性要求）；Web 远程桌面支持2个主机同时在线，如需突破此限制，请联系管理员。
+

+# 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. 技术方案总览
+
+### 2.1 编码器优先级链
+

+                                  x264 软编（始终可用）
+```
+
+### 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
+```

+    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 {

+    virtual ~VideoEncoderBase() = default;
+
+    virtual bool open(const EncoderParams& params) = 0;
+    virtual void close() = 0;

+    virtual int encode(
+        uint8_t* rgb,

+        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

+```
+
+#### 6.3.4 RGB24 → NV12（libyuv 无直接 API，两步走）
+
+```cpp
+int CFFmpegH264Encoder::convertToNV12(uint8_t* rgb, uint8_t /*bpp*/,

+    int uv_size = (width / 2) * (height / 2);
+    m_i420Scratch.resize(y_size + 2 * uv_size);
+
+    uint8_t* y = m_i420Scratch.data();
+    uint8_t* u = y + y_size;
+    uint8_t* v = u + uv_size;
+
+    libyuv::RGB24ToI420(
+        rgb, stride,
+        y, width,
+        u, width / 2,
+        v, width / 2,
+        width, signed_height
+    );

+        m_frame->data[1], m_frame->linesize[1],
+        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
+
+`EncoderFactory.h`：
+
+```cpp
+#pragma once
+#include "VideoEncoderBase.h"
+#include <memory>
+
+struct ClientCapability {
+    bool supportAV1  = false;
+    bool supportH264 = true;   // 假定都支持
+};
+
+struct EncoderRequest {
+    int width, height, fps;
+    int bitrate_kbps;
+    ClientCapability client;
+};
+
+std::unique_ptr<VideoEncoderBase> CreateEncoder(const EncoderRequest& req);
+```
+
+`EncoderFactory.cpp`：
+
+```cpp
+#include "EncoderFactory.h"
+#include "EncoderProbe.h"
+#include "CFFmpegAV1Encoder.h"
+#include "CFFmpegH264Encoder.h"
+#include "X264Encoder.h"
+
+std::unique_ptr<VideoEncoderBase> CreateEncoder(const EncoderRequest& req) {
+    EncoderParams p;
+    p.width  = req.width;
+    p.height = req.height;
+    p.fps    = req.fps;
+
+    // 1. AV1 路径（仅当客户端支持且启动探测确认硬件可用）
+    if (req.client.supportAV1 && EncoderProbe::HasAV1Hw()) {
+        auto enc = std::make_unique<CFFmpegAV1Encoder>();
+        p.rc = RateControl::BITRATE;
+        p.bitrate_kbps = req.bitrate_kbps;
+        if (enc->open(p)) {
+            LOG_INFO("encoder: AV1 backend=%s", enc->backendName());
+            return enc;
+        }
+        LOG_WARN("encoder: AV1 open failed, falling back to H.264");
+    }
+
+    // 2. H.264 硬编路径
+    if (EncoderProbe::HasH264Hw()) {
+        auto enc = std::make_unique<CFFmpegH264Encoder>();
+        p.rc = RateControl::BITRATE;
+        p.bitrate_kbps = req.bitrate_kbps;
+        if (enc->open(p)) {
+            LOG_INFO("encoder: H264-HW backend=%s", enc->backendName());
+            return enc;
+        }
+        LOG_WARN("encoder: H264 HW open failed, falling back to x264");
+    }
+
+    // 3. H.264 软编兜底（始终可用）
+    {
+        auto enc = std::make_unique<CX264Encoder>();
+        p.rc = RateControl::CRF;
+        p.crf = BitRateToCRF(req.bitrate_kbps);
+        if (enc->open(p)) {
+            LOG_INFO("encoder: H264-SW (libx264)");
+            return enc;
+        }
+    }
+
+    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
+
+---
+
+## 12. 参考资料
+

yuanyuanxiang	740ec8baf3	Perf(license): mutex + write-suppression for licenses.ini hot path licenses.ini was hit on every heartbeat -- 5s x clients x ~8 SetStr per auth -- with no concurrency protection. Two consequences: 1. 100 concurrent online would saturate the file (~160 writes/sec, full-file rewrite each via WritePrivateProfileString). 2. Concurrent SetPendingRenewal / DecrementPendingQuota with no lock occasionally clobbered freshly-set renewal quotas (reported by user as "preset renewal silently disappears"). Add LicensesIniMutex() (Meyers singleton recursive_mutex, exposed in CPasswordDlg.h so both CPasswordDlg.cpp and CLicenseDlg.cpp share it) and wrap all 15 functions that touch licenses.ini. Rewrite UpdateLicenseActivity around g_activityCache (in-memory state keyed by "SN\|IP\|machine"): skip the entire write path when nothing changed and the 30s LastActiveTime throttle window hasn't expired. Passcode/HMAC are only flushed on actual change (renewal path); IP list is only rewritten when the yyMMdd timestamp would roll a day. Measured impact (local 2-client baseline): before: 0.60 writes/sec (4 writes per heartbeat cluster) after: 0.07 writes/sec (one write per client per 30s throttle) Extrapolated to the 100-online target: before: ~160 writes/sec (saturation) after: ~3.3 writes/sec (100 clients / 30s throttle window) Race elimination is the more important win: PendingQuota's read-modify-write is now atomic, so the "preset renewal disappears" race is closed. Notes from audit (these landed during the same iteration): - Cache key is (SN, IP, machine), not SN alone. A single SN can be shared by 100+ end machines in bulk-license deployments, so a per-SN cache flips on every heartbeat and defeats suppression. Per-(SN, IP, machine) throttling is what makes the 100/30 model actually hold; an SN-only key reproduced the original ~0.7 writes/s. - DeleteLicense invalidates the per-SN activity cache via InvalidateLicenseActivityCache() (prefix scan since one SN maps to many cache entries). Without this, cache hits after delete would skip the auto-recreate path and leave the section permanently missing. - OnLicenseViewIPs: m_ListLicense.SetItemText moved outside the lock so the critical section only covers disk I/O.	2026-05-22 00:31:54 +02:00
