Smart IPC 场景功能
本文将以 V821 PERF2 板为示例，演示搭建 Smart IPC 场景功能，包括：
- RTSP H264 1280*720@20fps 预览
- 1280*720@20fps H264 编码视频分段滚动录像
- 定时拍照
需要准备如下物品：
- V821 PERF2 开发板
- 单目GC1084模组
- 串口线（用于调试）
- USB线（用于下载烧录，传输文件）
- SD 卡（用于保存码流）
- WIFI天线（用于无线传输）
- 路由器（用于数据交换）
- 手机或笔记本电脑（用于播放码流）
硬件连接
准备好摄像头，排线，V821 PERF2 开发板，排线需要同向排线。
将排线的蓝面朝上，接入摄像头模块
排线另外一边，触点面朝向芯片，接入 PERF2 开发板
摄像头安装完成
安装天线，将天线接入天线插口
插入调试串口
准备固件
如果已有固件，可以跳过本章节，从烧录固件开始看
配置方案
首先输入以下命令，配置SDK开发环境
source build/envsetup.sh
然后输入 lunch 命令加载方案
lunch
这里选择 v821-perf2-tina 方案，输入 4，按回车
配置测试 Sample
Loading asciinema cast...
输入以下命令，进入配置界面
make menuconfig
配置页面如下
下拉找到 Allwinner 按回车进入
在最下面找到 eyesee-mpp，按回车进入
找到 select mpp sample，按空格选中
找到 mpp sample smartIPC_demo，按空格选中
提示
备注
提示
备注
如果找不到 mpp sample smartIPC_demo 选项，先去检查一下依赖软件包 rgb_ctrl 有没有打开，如果没有打开需要开一下
:::
使用方向键选择 Save
选择 OK
选择 EXIT
使用方向键选择 Exit
继续退出
继续退出
编译 SDK
回到控制台，输入 mp -j4 以 4 线程并行方式编译
等待 SDK 编译完成，会在 out 目录下生成固件
将固件拷贝出来，准备烧录
烧写固件
打开 PhoenixSuit，选择一键刷机，点击浏览，打开刚才生成的固件
选择全盘擦除升级
按住 PERF2 开发板上的FEL按键，插入USB线
烧录工具出现提示，选择是
烧录中，请耐心等待
烧写结束，系统自动启动
配置 Sample
前往 platform/allwinner/eyesee-mpp/middleware/sun300iw1/sample/bin 找到刚才编译出来的Sample
编辑 sample_smartIPC_demo.conf 修改配置文件，需要修改的项目如下（可以在附录获取完整版配置文件）：
stream_buf_size = -1 # 使用码流大小推流
main_rtsp_id = 0 # 启用 RTSP
main_src_frame_rate = 20 # 帧率设置 20 帧
main_encode_frame_rate = 20 # 配置编码器20帧
main_2nd_enable = 1 # 开启子码流
main_2nd_src_frame_rate = 20 # 子码流帧率20帧
main_2nd_encode_frame_rate = 20 # 子码流编码帧率20帧
main_2nd_take_picture = 1 # 子码流开启拍照功能
将SD卡格式化为 FAT32 格式
将上面编译出来的 sample 和 配置文件复制到 SD 卡里
测试运行 Sample
配置无线网络
使用命令扫描无线网络
wifi -s
使用命令连接无线网络，连接成功后使用 ifconfig 命令查看连接情况与 IP 地址
wifi -c <SSID> <密码>
ifconfig wlan0
挂载 SD 卡
插入 SD 卡后，可以在日志里看到新生成的卡设备
使用命令挂载 SD 卡
mount /dev/mmcblk0p1 /mnt/extsd
运行 Sample
前往SD卡的挂载目录，查看文件是否存在
cd /mnt/extsd
使用命令，运行 sample
./sample_smartIPC_demo -path sample_smartIPC_demo.conf &
在平板上打开 VLC 播放器。配置日志显示的地址
rtsp://192.168.51.101:8554/ch0
即可打开串流视频
SD 卡插上电脑也可以看到拍到的图片和码流
