https://blog.csdn.net/djj199301111/category_11383635.html?spm=1001.2014.3001.5482
JP 4.4.1 deepstream 5.0 参考之前的文章：
https://blog.csdn.net/djj199301111/article/details/110186640

环境

JP 4.6.1
deepstream 6.0.1

安装依赖及Gstreamer

sudo apt-get install libssl1.0.0  libgstreamer1.0-0 gstreamer1.0-tools gstreamer1.0-plugins-good gstreamer1.0-plugins-bad  gstreamer1.0-plugins-ugly gstreamer1.0-libav libgstrtspserver-1.0-0 libjansson4 ffmpeg

sudo apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio libgstrtspserver-1.0-dev gstreamer1.0-rtsp

sudo apt-get install libgstreamer-plugins-base1.0-dev libgstreamer1.0-dev  libx11-dev libjson-glib-dev  libgirepository1.0-dev

官网下载对应安装包

下载对应jetson的sdk的tar包

https://developer.nvidia.com/deepstream-getting-started

安装

sudo tar -jxvf deepstream_sdk_v6.0.1_jetson.tbz2 -C /
cd /opt/nvidia/deepstream/deepstream-6.0/
sudo ./install.sh
sudo ldconfig

添加环境变量

sudo vim /etc/ld.so.conf
#添加下行在文件最后
/opt/nvidia/deepstream/deepstream-6.0/lib/ 
 
sudo ldconfig    #立即生效

为了避免报错 No EGL Display 环境变量下添加unset DISPLAY。

#还要添加
sudo vim ~/.bashrc
#最后面添加
unset DISPLAY

#保存退出，生效一下
source ~/.bashrc

查看deepstearm安装情况

deepstream-app --version-all

运行案例（）：

cd /opt/nvidia/deepstream/deepstream
#测试案例
deepstream-app -c samples/configs/deepstream-app/source8_1080p_dec_infer-resnet_tracker_tiled_display_fp16_nano.txt

如果如下错误：

需要删除缓冲文件

sudo rm ~/.cache/gstreamer-1.0/*

正常运行输出为：

Deepstearm + Python API

• 最新版的python api 官方有编译好的whl下载直接安装就可以：

pyds whl 下载地址：
https://github.com/NVIDIA-AI-IOT/deepstream_python_apps/releases

#默认会安装  pgi-0.0.11.2 和 pyds-1.1.1
sudo pip3 install pyds-1.1.1-py3-none-linux_aarch64.whl

• 案例测试

cd /opt/nvidia/deepstream/deepstream/sources
sudo git clone https://github.com/NVIDIA-AI-IOT/deepstream_python_apps

cd /opt/nvidia/deepstream/deepstream/sources/deepstream_python_apps/apps/deepstream-test1
python3 deepstream_test_1.py /opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264

• 显示推理视频说明成功；不过python的api方式使用，配置起来感觉更加麻烦。
