## 安装教程
[deepstream-6.2 dGPU Setup](https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_Quickstart.html#dgpu-setup-for-ubuntu)

其他依赖组件
- GStreamer-1.0
- GStreamer-1.0 Base Plugins
- GStreamer-1.0 gstrtspserver
- X11 client-side library
- Glib json library - json-glib-1.0
- yaml-cpp

``` bash
# 安装
sudo apt-get install libgstreamer-plugins-base1.0-dev libgstreamer1.0-dev \
   libgstrtspserver-1.0-dev libx11-dev libjson-glib-dev libyaml-cpp-dev
```

## 使用说明

```bash
# 运行分类程序
$ ./cls 

# 运行检测程序
$ ./det detection/config/config.yml

# docker镜像启动容器
$ docker run --gpus all -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY --net=host <image_name> bash
```

当视频文件为HEVC/265编码时，source插件可能不支持，需要转为AVC/264编码格式，使用如下命令
```bash
$ ffmpeg -i hevc.mp4 -c:v libx264 avc.mp4
```
## 特技

### cuda延迟加载
cuda lazy loading can reduce device memory usage and speed up TensorRT initializion.[Ref](https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#lazy-loading)

```bash
# set this to enable lazing loading
export CUDA_MODULE_LOADING=LAZY
```

### 安装rtspclientsink
rtspclientsink plugin is not part of the basic three plugin packages. You need to install it separately. To install it, run the following command:
```
sudo apt install gstreamer1.0-rtsp
```

## 开发计划

- 构建分类模型的IVA应用 classification
- 构建检测模型的IVA应用 ds-detection
- 构建分割模型的IVA应用 ds-segmentation
- 检测+跟踪+分类IVA应用 ds-app
