+# RK3588S 依赖安装指南
+
+## 系统要求
+
+- **硬件**: Orange Pi 5 / 5 Plus 或其他 RK3588/RK3588S 设备
+- **系统**: Ubuntu 22.04 LTS 或 Debian 11 (ARM64)
+- **内核**: 5.10.x (带 Rockchip 驱动)
+
+## 快速安装
+
+使用一键安装脚本：
+
+```bash
+# 1. 克隆或复制项目到新设备
+cd ~/apps/OrangePi3588Media
+
+# 2. 运行依赖安装脚本
+sudo ./scripts/install_deps.sh
+```
+
+## 手动安装步骤
+
+如果脚本安装失败，可按以下步骤手动安装：
+
+### 1. 基础工具
+
+```bash
+sudo apt-get update
+
+sudo apt-get install -y \
+    build-essential cmake git wget curl pkg-config \
+    libdrm-dev libx11-dev libxext-dev libgles2-mesa-dev \
+    libwayland-dev libpulse-dev libasound2-dev libv4l-dev \
+    python3 python3-pip python3-dev \
+    htop vim net-tools ffmpeg v4l-utils
+```
+
+### 2. Rockchip MPP (硬件编解码)
+
+```bash
+cd /tmp
+git clone https://github.com/rockchip-linux/mpp.git
+cd mpp
+mkdir build && cd build
+cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DHAVE_DRM=ON
+make -j$(nproc)
+sudo make install
+sudo ldconfig
+```
+
+**验证**:
+```bash
+pkg-config --modversion rockchip_mpp
+```
+
+### 3. Rockchip RGA (2D图形加速)
+
+```bash
+cd /tmp
+git clone https://github.com/rockchip-linux/rkrga.git
+cd rkrga
+mkdir build && cd build
+cmake .. -DCMAKE_INSTALL_PREFIX=/usr
+make -j$(nproc)
+sudo make install
+sudo ldconfig
+```
+
+### 4. RKNN Runtime (NPU推理)
+
+```bash
+# 方法1: 使用项目内置版本（推荐）
+# 项目已包含 third_party/rknpu2
+
+# 方法2: 手动下载安装
+cd /tmp
+wget https://github.com/rockchip-linux/rknpu2/releases/download/v1.6.0/rknpu2_1.6.0_arm64.deb
+sudo dpkg -i rknpu2_1.6.0_arm64.deb
+
+# Python包
+pip3 install rknn-toolkit2-lite2
+```
+
+**验证**:
+```bash
+ls /dev/rknpu*
+cat /proc/rknpu/version
+```
+
+### 5. FFmpeg (带Rockchip支持)
+
+```bash
+cd /tmp
+git clone https://github.com/nyanmisaka/ffmpeg-rockchip.git
+cd ffmpeg-rockchip
+
+# 安装依赖
+sudo apt-get install -y \
+    libgnutls28-dev libaom-dev libdav1d-dev \
+    libmp3lame-dev libopus-dev libtheora-dev \
+    libvorbis-dev libvpx-dev libx264-dev libx265-dev libnuma-dev
+
+# 配置编译
+./configure \
+    --prefix=/usr/local \
+    --enable-gpl --enable-version3 \
+    --enable-libdrm --enable-rkmpp --enable-rkrga \
+    --enable-libx264 --enable-libx265 \
+    --enable-shared --disable-static
+
+make -j$(nproc)
+sudo make install
+sudo ldconfig
+```
+
+**验证**:
+```bash
+ffmpeg -version
+ffmpeg -encoders | grep rkmpp
+```
+
+### 6. 系统配置
+
+```bash
+# NPU设备权限
+sudo tee /etc/udev/rules.d/99-rockchip-npu.rules << 'EOF'
+KERNEL=="rknpu*", MODE="0666", GROUP="video"
+KERNEL=="mpp_service", MODE="0666", GROUP="video"
+KERNEL=="rga*", MODE="0666", GROUP="video"
+EOF
+
+sudo udevadm control --reload-rules
+sudo udevadm trigger
+
+# 添加用户到video组
+sudo usermod -a -G video $USER
+```
+
+## 依赖检查清单
+
+安装完成后，运行以下检查：
+
+```bash
+# 1. NPU设备
+ls -la /dev/rknpu*          # 应该显示 /dev/rknpu, /dev/rknpu0 等
+
+# 2. MPP库
+pkg-config --modversion rockchip_mpp
+
+# 3. RKNN库
+ls /usr/lib/librknnrt.so || ls /usr/lib/aarch64-linux-gnu/librknnrt.so
+
+# 4. FFmpeg
+ffmpeg -version | head -1
+
+# 5. 内核模块
+lsmod | grep rknpu
+lsmod | grep mpp
+```
+
+## 常见问题
+
+### Q: NPU设备不存在
+```bash
+# 检查内核模块
+lsmod | grep rknpu
+
+# 如果没有，尝试手动加载
+sudo modprobe rknpu
+
+# 或者检查dts是否启用了NPU
+dmesg | grep -i rknpu
+```
+
+### Q: MPP编译失败
+```bash
+# 确保安装了libdrm-dev
+sudo apt-get install -y libdrm-dev
+
+# 或者禁用DRM支持
+cmake .. -DHAVE_DRM=OFF
+```
+
+### Q: FFmpeg找不到rkmpp
+```bash
+# 确保MPP已正确安装并更新pkg-config
+pkg-config --cflags rockchip_mpp
+
+# 如果失败，手动指定路径
+./configure --extra-cflags="-I/usr/include" --extra-ldflags="-L/usr/lib"
+```
+
+### Q: RKNN模型加载失败
+```bash
+# 检查驱动版本
+cat /proc/rknpu/version
+
+# 确保模型版本与驱动匹配
+# RKNN-Toolkit2 1.6+ 需要驱动 0.9.6+
+```
+
+## 版本兼容性
+
+| 组件 | 推荐版本 | 说明 |
+|-----|---------|------|
+| MPP | git master | 硬件编解码 |
+| RGA | git master | 2D加速 |
+| RKNN Runtime | 1.6.0+ | NPU推理 |
+| FFmpeg | 6.0+ (rockchip) | 带rkmpp/rkrga支持 |
+| CMake | 3.16+ | 编译工具 |
+| GCC | 9.0+ | 编译器 |
