修复录屏0字节问题，支持压力板多厂家切换

- 录屏: 高DPI缩放导致奇数尺寸触发libx264编码失败,宽高取偶; ffmpeg stderr写入日志

- 压力板: 新增 pressure_manager_small.py 原厂家小压力板,与现有大压力板并存

- 打包: 新增 build_backend.ps1,更新 requirements_build.txt / config.ini

- 前端: Electron 本地化配置

+# 多厂家足底压力板适配开发方案
+
+## 1. 需求背景与目标
+
+当前系统使用足底压力板采集足底压力数据。项目经历了一次设备更换：
+
+| 设备 | 程序文件 | 状态 |
+| --- | --- | --- |
+| 原厂家（小一号压力板，SMiTSense USB） | `backend/devices/pressure_manager_small.py` | 已停用 |
+| 新厂家（大一号压力板，X2 共享内存） | `backend/devices/pressure_manager.py` | 当前使用 |
+
+**需求目标**：程序同时支持两个厂家的设备，通过**配置文件参数**切换使用哪个厂家，无需修改代码、重新打包即可在两种设备间切换。
+
+具体拆解为三点：
+1. 新增配置文件参数，用 `small` 代表原厂家设备（对应 `pressure_manager_small.py`），用 `large` 代表新厂家设备（对应 `pressure_manager.py`）；
+2. 修改配置与初始化程序，根据配置文件**动态初始化**对应厂家的设备管理器；
+3. 检测时，根据配置文件**加载对应厂家**的设备进行数据采集。
+
+---
+
+## 2. 现状分析
+
+### 2.1 两个压力板管理器的异同
+
+两个文件均定义了 `class PressureManager(BaseDevice)`，对外接口**完全一致**：
+
+- 生命周期：`initialize()` / `start_streaming()` / `stop_streaming()` / `disconnect()` / `cleanup()` / `restart` 相关
+- 配置：`reload_config()` / `get_status()` / `calibrate()`
+- 数据上报：均通过 Socket.IO 以 `pressure_data` 事件推送到 `/devices` 命名空间，数据结构相同（`foot_pressure` + `pressure_image` + `timestamp`）
+
+因此**前端无需任何改动**，只需要保证后端"按配置加载正确的管理器类"即可。
+
+底层设备实现差异：
+
+| 项目 | pressure_manager_small.py（原厂家） | pressure_manager.py（新厂家） |
+| --- | --- | --- |
+| 真实设备 | `RealPressureDevice`（SMiTSense `Wrapper.dll` USB 读取） | `SharedMemoryPressureDevice`（X2 共享内存）为主，同时保留 `RealPressureDevice` |
+| 模拟设备 | `MockPressureDevice` | `MockPressureDevice` |
+| 数据源切换方式 | 仅 `use_mock` | `use_mock` + `pressure_source`（`smitsense` / `shared_memory`） |
+| 与硬件耦合 | DLL 文件 `dll/smitsense/Wrapper.dll` | 共享内存名 `x2_pressure` 等一批 `pressure_shared_memory_*` 参数 |
+
+### 2.2 当前硬编码点（需要改造的位置）
+
+现有代码在多处**直接 import 并实例化 `pressure_manager.PressureManager`**，这是需要改造的核心：
+
+| 文件 | 行号 | 现状 |
+| --- | --- | --- |
+| `backend/devices/device_coordinator.py` | L19 / L26 | 模块顶部 `from .pressure_manager import PressureManager` |
+| `backend/devices/device_coordinator.py` | L421-436 | `_init_pressure()` 直接 `PressureManager(self.socketio, self.config_manager)` |
+| `backend/devices/device_coordinator.py` | L837-842 | `restart_device('pressure')` 分支再次直接 import + 实例化 |
+| `backend/main.py` | L33 | 模块顶部 `from devices.pressure_manager import PressureManager` |
+| `backend/devices/__init__.py` | L11 / L19 | `from .pressure_manager import PressureManager` 并导出 |
+
+### 2.3 配置现状
+
+`[DEVICES]` 段已有压力板相关参数（`backend/config.ini` 与打包产物 `backend/dist/BodyBalanceBackend/config.ini` 内容一致）：
+
+```ini
+[DEVICES]
+; pressure_enable = True
+; pressure_use_mock = True
+pressure_enable = False
+pressure_use_mock = True
+pressure_source = shared_memory
+pressure_shared_memory_name = x2_pressure
+pressure_shared_memory_header_bytes = 72
+pressure_shared_memory_rows = 288
+pressure_shared_memory_cols = 64
+pressure_shared_memory_dtype = float32
+pressure_shared_memory_crop_rows = 0
+pressure_shared_memory_low_percentile = 5
+pressure_shared_memory_high_percentile = 98
+pressure_shared_memory_gamma = 1.0
+pressure_shared_memory_ema_alpha = 0.1
+```
+
+`ConfigManager._get_pressure_config()` 目前只返回 `enable / use_mock / port / baudrate` 四个字段；`pressure_source` 及 `pressure_shared_memory_*` 由 `pressure_manager.py` 内部通过 `get_config_value('DEVICES', ...)` 直接读取。
+
+---
+
+## 3. 设计方案
+
+### 3.1 新增配置参数：`pressure_vendor`
+
+在 `[DEVICES]` 段新增参数，作为**厂家选择的总开关**：
+
+```ini
+[DEVICES]
+pressure_enable = True
+pressure_vendor = large        ; small = 原厂家（小压力板，pressure_manager_small.py）
+                               ; large = 新厂家（大压力板，pressure_manager.py）
+pressure_use_mock = False
+```
+
+**取值约定**（严格按需求）：
+- `small` → 加载 `pressure_manager_small.py` 中的 `PressureManager`
+- `large` → 加载 `pressure_manager.py` 中的 `PressureManager`
+- 未配置或非法值 → **默认回退为 `large`**（与当前线上部署行为一致，保证向后兼容）
+
+**厂商专用参数共存策略**：`small` 与 `large` 各自的参数（`pressure_source`、`pressure_shared_memory_*`、`pressure_dll_path` 等）全部保留在 `[DEVICES]` 段中，互不冲突。加载哪个管理器，就由哪个管理器读取自己关心的参数，其余参数被忽略，无需拆分配置段。
+
+### 3.2 新增设备工厂（适配器）：`pressure_device_factory.py`
+
+新建 `backend/devices/pressure_device_factory.py`，作为**唯一的压力板管理器入口**：
+
+```python
+#!/usr/bin/env python3
+# -*- coding: utf-8 -*-
+"""压力板设备工厂
+根据配置 [DEVICES] pressure_vendor 动态选择加载对应厂家的压力板管理器。
+small = 原厂家（pressure_manager_small.py）；large = 新厂家（pressure_manager.py）。
+"""
+import logging
+
+logger = logging.getLogger(__name__)
+
+# 静态导入两个厂家的管理器（静态导入可保证 PyInstaller 打包时两个模块都被收集）
+try:
+    from .pressure_manager_small import PressureManager as SmallPressureManager
+    from .pressure_manager import PressureManager as LargePressureManager
+except ImportError:
+    from pressure_manager_small import PressureManager as SmallPressureManager
+    from pressure_manager import PressureManager as LargePressureManager
+
+# 厂家注册表：配置值 -> 管理器类
+VENDOR_MAP = {
+    'small': SmallPressureManager,   # 原厂家（小压力板）
+    'large': LargePressureManager,   # 新厂家（大压力板）
+}
+
+DEFAULT_VENDOR = 'large'             # 向后兼容：默认新厂家
+
+
+def resolve_pressure_vendor(config_manager) -> str:
+    """读取配置中的厂家值，非法值回退为默认厂家"""
+    try:
+        vendor = str(
+            config_manager.get_config_value('DEVICES', 'pressure_vendor', fallback=DEFAULT_VENDOR)
+        ).strip().lower()
+    except Exception as e:
+        logger.warning(f'读取 pressure_vendor 失败，使用默认厂家 {DEFAULT_VENDOR}: {e}')
+        vendor = DEFAULT_VENDOR
+    if vendor not in VENDOR_MAP:
+        logger.warning(f'未知 pressure_vendor: {vendor}，回退为 {DEFAULT_VENDOR}')
+        vendor = DEFAULT_VENDOR
+    return vendor
+
+
+def get_pressure_manager_class(config_manager):
+    """根据配置返回对应的压力板管理器类"""
+    vendor = resolve_pressure_vendor(config_manager)
+    cls = VENDOR_MAP[vendor]
+    logger.info(f'压力板厂家选择: {vendor} -> {cls.__module__}.{cls.__name__}')
+    return cls
+
+
+def create_pressure_manager(socketio, config_manager):
+    """创建压力板管理器实例（对外统一入口）"""
+    cls = get_pressure_manager_class(config_manager)
+    return cls(socketio, config_manager)
+```
+
+**要点**：
+- 采用**静态 import 两个模块**而非 `importlib` 动态导入——因为 PyInstaller 的静态分析能识别 `from X import Y`，确保打包时两个厂家模块都被打进 exe，避免打包后切厂家时报"模块不存在"。
+- 对外只暴露 `create_pressure_manager(socketio, config_manager)` 一个入口，调用方不关心具体厂家。
+
+### 3.3 初始化流程改造（动态初始化）
+
+#### (1) `backend/devices/device_coordinator.py`
+
+- 顶部 import（L19/L26）：不再直接导入 `PressureManager`，改为导入工厂：
+
+  ```python
+  try:
+      from .pressure_device_factory import create_pressure_manager
+  except ImportError:
+      from pressure_device_factory import create_pressure_manager
+  ```
+
+- `_init_pressure()`（L421-436）改为：
+
+  ```python
+  def _init_pressure(self) -> bool:
+      try:
+          pressure = create_pressure_manager(self.socketio, self.config_manager)
+          self.devices['pressure'] = pressure
+          if pressure.initialize():
+              return True
+          return False
+      except Exception as e:
+          self.logger.error(f"初始化压力传感器失败: {e}")
+          return False
+  ```
+
+- `restart_device()` 的 `pressure` 分支（L837-842）同步改为：
+
+  ```python
+  elif device_name == 'pressure':
+      new_device = create_pressure_manager(self.socketio, self.config_manager)
+  ```
+
+  这样**在运行中修改 `pressure_vendor` 后调用"设备重启"接口即可热切换厂家**，无需重启整个后端。
+
+#### (2) `backend/main.py`
+
+- L33 `from devices.pressure_manager import PressureManager`：该导入在 main.py 中并未被实际调用（压力板实例统一由协调器持有），建议**删除该行**，避免与工厂逻辑冲突；若确需引用，改为从工厂获取类。
+
+#### (3) `backend/devices/__init__.py`
+
+- L11 / L19：`PressureManager` 导出改为通过工厂间接暴露，建议调整为：
+
+  ```python
+  from .pressure_device_factory import create_pressure_manager, get_pressure_manager_class
+  ```
+
+  对外不再直接导出某个厂家的 `PressureManager` 类，统一走工厂。
+
+### 3.4 检测时加载对应设备（需求点 3）
+
+检测流程（`main.py` 的检测启动、数据采集）**均通过 `DeviceCoordinator` 获取压力板实例**（`self.device_coordinator.get_device('pressure')` / `device_managers`），而协调器在初始化时已经按 `pressure_vendor` 创建了正确厂家的实例，因此检测时天然加载的就是配置指定厂家的设备，**无需改动检测主流程**。
+
+补充两个健壮性措施（建议纳入实现）：
+1. **检测启动前校验**：在检测开始接口中读取 `pressure_vendor`，与当前压力板实例的 `__class__.__module__` 对比，若不一致则记录告警日志（提示"配置已切换但设备未重启"），引导用户通过设备重启接口热切换。
+2. **配置变更热切换**：前端"设备设置"保存 `pressure_vendor` 后，后端提示"重启软件系统生效"（沿用现有 `set_all_device_configs` 的提示语）；同时支持在设备管理页调用现有 `restart_device('pressure')` 立即切换。
+
+### 3.5 配置管理 / API 支持
+
+`backend/devices/utils/config_manager.py`：
+
+- `_get_pressure_config()`（L243-255）新增返回 `vendor` 字段：
+
+  ```python
+  return {
+      'enable': self.config.getboolean('DEVICES', 'pressure_enable', fallback=False),
+      'use_mock': self.config.getboolean('DEVICES', 'pressure_use_mock', fallback=False),
+      'vendor': self.config.get('DEVICES', 'pressure_vendor', fallback='large'),
+      'port': self.config.get('DEVICES', 'pressure_port', fallback='COM8'),
+      'baudrate': self.config.getint('DEVICES', 'pressure_baudrate', fallback=115200),
+  }
+  ```
+
+- `_batch_update_device_configs()` 的 `pressure` 分支（L453-475）新增：
+
+  ```python
+  if 'vendor' in config_data:
+      self.set_config_value('DEVICES', 'pressure_vendor', str(config_data['vendor']))
+  ```
+
+这样前端设备设置页（如果暴露压力板配置）可读写 `pressure_vendor`，走既有的 `set_all_device_configs` 接口即可。
+
+### 3.6 打包注意事项（PyInstaller）
+
+- 工厂采用**静态导入**两个厂家模块，PyInstaller 会自动收集 `pressure_manager_small.py` 与 `pressure_manager.py`，一般无需额外配置。
+- 稳妥起见，在 `backend/build_app.py` 生成的 `app.spec` 的 `hiddenimports` 中追加：
+
+  ```python
+  hiddenimports=['devices.pressure_manager_small', 'devices.pressure_manager', 'devices.pressure_device_factory'],
+  ```
+
+- 若某厂家依赖额外 DLL（`dll/smitsense/Wrapper.dll`），需确认打包时该 DLL 已被收集（`build_app.py` 后处理逻辑中已包含 dll 目录拷贝，需核对 smitsense 子目录是否在内）。
+
+---
+
+## 4. 配置文件示例
+
+### 4.1 使用新厂家（大压力板，当前部署）
+
+```ini
+[DEVICES]
+pressure_enable = True
+pressure_vendor = large
+pressure_use_mock = False
+pressure_source = shared_memory
+pressure_shared_memory_name = x2_pressure
+pressure_shared_memory_header_bytes = 72
+pressure_shared_memory_rows = 288
+pressure_shared_memory_cols = 64
+pressure_shared_memory_dtype = float32
+; ... 其余 pressure_shared_memory_* 参数保持不变 ...
+```
+
+### 4.2 使用原厂家（小压力板）
+
+```ini
+[DEVICES]
+pressure_enable = True
+pressure_vendor = small
+pressure_use_mock = False
+; pressure_source / pressure_shared_memory_* 无需改动，small 管理器会忽略它们
+```
+
+### 4.3 无硬件联调（模拟数据）
+
+```ini
+pressure_enable = True
+pressure_vendor = small   ; 或 large，均可
+pressure_use_mock = True
+```
+
+---
+
+## 5. 兼容性与迁移
+
+| 场景 | 说明 |
+| --- | --- |
+| 旧配置无 `pressure_vendor` | 工厂回退为 `large`，与当前线上行为一致，**无感知迁移** |
+| 前端无改动 | 两个管理器数据上报协议一致（`pressure_data` / `/devices`），前端不用改 |
+| 运行中切换厂家 | 通过既有 `restart_device('pressure')` 接口热切换；或改配置后重启后端 |
+| 模拟/真实切换 | 沿用各管理器内部 `pressure_use_mock` 逻辑，不受厂家切换影响 |
+
+---
+
+## 6. 测试计划
+
+1. **工厂单元验证**（venv 下直接调用）：
+   - `pressure_vendor=small` → `get_pressure_manager_class()` 返回 `pressure_manager_small.PressureManager`
+   - `pressure_vendor=large` → 返回 `pressure_manager.PressureManager`
+   - `pressure_vendor=非法值/缺省` → 回退 `large`，日志有告警
+2. **集成验证**（`pressure_use_mock=True`，不接硬件）：
+   - `large`：协调器初始化 → 压力板连接成功 → `start_streaming` → 收到 `pressure_data` 事件
+   - `small`：同上流程验证
+3. **热切换验证**：`set_all_device_configs` 修改 `pressure_vendor` → 调用 `restart_device('pressure')` → 日志确认切换为另一厂家、数据流恢复
+4. **检测回归**：登录 → 创建检测 → 检测过程压力数据正常采集与保存
+5. **打包回归**：`build_backend.ps1` 打包后，分别在两种配置下运行 exe 验证初始化与数据流

+## 7. 文件修改清单
+
+| 文件 | 操作 | 说明 |
+| --- | --- | --- |
+| `backend/devices/pressure_device_factory.py` | **新增** | 厂家注册表 + `create_pressure_manager` 工厂入口 |
+| `backend/devices/device_coordinator.py` | 修改 | 顶部 import、`_init_pressure()`、`restart_device()` pressure 分支改用工厂 |
+| `backend/main.py` | 修改 | 移除/替换 L33 直接导入 |
+| `backend/devices/__init__.py` | 修改 | 导出改为工厂接口 |
+| `backend/devices/utils/config_manager.py` | 修改 | `_get_pressure_config()` 增加 `vendor`；批量更新支持 `vendor` |
+| `backend/config.ini` | 修改 | `[DEVICES]` 增加 `pressure_vendor = large` |
+| `backend/dist/BodyBalanceBackend/config.ini` | 修改 | 同步增加 `pressure_vendor = large` |
+| `backend/build_app.py` | 修改 | `app.spec` 增加 `hiddenimports`（稳妥项） |
+| `document/多厂家足底压力板适配开发方案.md` | 新增 | 本文档 |
+
+---
+
+## 8. 风险与注意事项
+
+1. **DLL 与硬件耦合**：`small` 厂家依赖 `dll/smitsense/Wrapper.dll`，切换回 `small` 时需确保该 DLL 存在于打包产物中；`large` 厂家依赖 X2 上位机软件创建的共享内存 `x2_pressure`，需先启动厂家采集程序。
+2. **打包收集**：若日后将工厂改为 `importlib` 动态导入，必须同步在 `app.spec` 的 `hiddenimports` 中显式声明两个厂家模块，否则打包后切换厂家会 ImportError。
+3. **两个模块内的 `RealPressureDevice` 重名**：`small` 与 `large` 模块内部都有同名类，工厂按模块隔离引用，不产生冲突，但**禁止**在外部直接 `from xxx import RealPressureDevice` 混用。
+4. **检测中切换厂家**：检测进行中不建议切换（会导致数据源中断），热切换应在非检测时段执行；检测启动前的"配置校验告警"可辅助提醒。
+5. **`pressure_source` 语义**：`large` 管理器内部仍以 `pressure_source`（`smitsense`/`shared_memory`）选择底层设备实现；本次方案中的 `pressure_vendor` 是"选哪个管理器文件"的更上层开关，两者不冲突、各司其职。
