示例

示例地址：https://github.com/NVIDIA-AI-IOT/deepstream_reference_apps 。克隆其到 `/opt/nvidia/deepstream/deepstream_reference_apps 。

模型文件：/opt/nvidia/deepstream/deepstream-5.0/samples/models

示例文档：https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_ref_app_github.html  


安装依赖：
查看：/opt/nvidia/deepstream/deepstream/sources/apps/sample_apps/deepstream-app/README  
命令：   
sudo apt-get install libgstreamer-plugins-base1.0-dev libgstreamer1.0-dev \
   libgstrtspserver-1.0-dev libx11-dev libjson-glib-dev
编译：make （验证SDK、依赖是否完备）。  

将 anomaly 拷贝到 /opt/nvidia/deepstream/deepstream/sources/apps/sample_apps/ ：
cp  /opt/nvidia/deepstream/deepstream_reference_apps/anomaly/ /opt/nvidia/deepstream/deepstream/sources/apps/sample_apps/ 

进入目录：
cd /opt/nvidia/deepstream/deepstream/sources/apps/sample_apps/anomaly
编译库：
cd plugins/gst-dsdirection/
make && sudo make install

编辑 ./anomaly/apps/deepstream-anomaly-detection-test/dsanomaly_pgie_config.txt 文件。


2个示例：
cd /opt/nvidia/deepstream/deepstream_reference_apps/anomaly/apps/deepstream-anomaly-detection-test
./deepstream-anomaly-detection-app  /opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264

cd /opt/nvidia/deepstream/deepstream_reference_a
-to-back-detectors
./back-to-back-detectors /opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264

出错及解决：

提示：

其他Github上的APP例子：

360度智能停车App

演示了一个或者多个360度视角的视频流的矫正功能。从一个CSV文件中读取摄像机矫正参数，然后将矫正后的过道和区域画面，呈现在屏幕上。

https://github.com/NVIDIA-AI-IOT/deepstream_360_d_smart_parking_application

DeepStream SDK for Redaction

重点展示如何在DeepStream里，对一个视频流，同时对人脸区域和车牌区域进行模糊， 也展示了当该DeepStream流水线风格的应用程序在运行的时候，动态的添加删除视频流通道。

https://github.com/NVIDIA-AI-IOT/redaction_with_deepstream

异常检测参考应用

使用并行管道处理2个流的示例应用程序。

https://github.com/NVIDIA-AI-IOT/deepstream_reference_apps/tree/master/anomaly

是否有关于动态流管理的例子吗?

https://github.com/NVIDIA-AI-IOT/deepstream_reference_apps/tree/master/anomaly

里面包括了在管道运行时动态添加或删除通道。
