运行Demo：

neardi@LPA3588:~/hailo8/hailo8_ak_rockit$ ./run_demo.sh

该Demo对16路1080P@30fps的H265视频流进行分析，成功执行后的画面如下：

注意：如果在终止Demo进程后出现黑屏，重新插拔HDMI线即可恢复显示。

5.从摄像头读取视频并进行分析

克隆hailo8_yolo5_demo代码库：

sudo apt update
git clone https://gitee.com/ytlans/hailo8_yolo5_demo

安装编译环境：

sudo apt update
sudo apt install build-essential cmake

编译Demo：

neardi@LPA3588:~/hailo8/hailo8_yolo5_demo/Apps/yolo$ ./build.sh
