1. 源由

为了更好的使用Jetson上AI开发环境，通过wfb-ng将穿越机/无人机的视频以及控制链路引入后端分析。

这里将Step by Step简单介绍下wfb-ng开源代码在Jetson Orin的安装过程。

2. 准备

硬件：

Jetson Orin 开发板
RTL8812AU网卡
OpenIPC FPV摄像头

软件：开源，一切都是开源的！！！请预装系统，推荐使用Linux 35.5 + JetPack v5.1.3，目前ROS上开源支持的比较广泛。

3. 步骤

3.1 DKMS安装

$ sudo apt-get install dkms
$ git clone git@github.com:svpcom/rtl8812au.git
$ cd rtl8812au
$ sudo ./dkms-install.sh

3.2 RTL8812AU驱动

$ make
$ sudo make install
$ sudo modprobe 88XXau_wfb

插入网卡：

$ sudo dmesg|tail -n 8
[ 1267.101046] usb 1-2.1: new high-speed USB device number 6 using tegra-xusb
[ 1267.207162] usb 1-2.1: config 1 interface 0 altsetting 0 endpoint 0x85 has an invalid bInterval 0, changing to 7

[ 1271.179209] IPv6: ADDRCONF(NETDEV_CHANGE): wlan1: link becomes ready

3.3 确认网卡

经检查RTL8812AU网卡实际系统中显示的是wlan1

$ ethtool -i wlan1
driver: rtl88xxau_wfb

supports-test: no
supports-eeprom-access: no

3.4 安装地面站

$ git clone -b stable https://github.com/svpcom/wfb-ng.git
$ cd wfb-ng
$ sudo ./scripts/install_gs.sh wlan1

3.5 wfg-ng服务操作

服务状态：

$ sudo systemctl status wifibroadcast@gs

启动服务：

$ sudo systemctl start wifibroadcast@gs

停止服务：

$ sudo systemctl stop wifibroadcast@gs

使能服务：

$ sudo systemctl enable wifibroadcast@gs

去使能服务：

$ sudo systemctl disable wifibroadcast@gs

3.6 其他操作

制作秘钥对，其中drone.key部署在天空端，而gs.key部署在地面端。

$ wfb_keygen

查看收发包状态：

$ wfb-cli gs

4. 总结

在jetson板子上仍然可以使用以下gstreamer命令进行解析RTP视频流：

H264

$ gst-launch-1.0 udpsrc port=5600 caps='application/x-rtp' ! rtph264depay ! h264parse disable-passthrough=true config-interval=1 ! nvv4l2decoder ! nvvidconv ! xvimagesink

H265，详见：H265 pipeline for gstreamer no video issue

$ gst-launch-1.0 udpsrc port=5600 caps='application/x-rtp' ! rtph265depay ! h265parse disable-passthrough=true config-interval=1 ! nvv4l2decoder ! nvvidconv ! xvimagesink

or 
$ gst-launch-1.0 udpsrc port=5600 caps='application/x-rtp,encoding-name=H265,payload=96' ! rtph265depay ! h265parse disable-passthrough=true config-interval=1 ! nvv4l2decoder ! nvvidconv ! xvimagesink

在jetson板子上使用video-viewer命令进行解析RTP视频流：

H264

$ video-viewer rtp://@:5600 --input-decoder=v4l2 --input-codec=h264

H265

$ video-viewer rtp://@:5600 --input-decoder=v4l2 --input-codec=h265

但是后续的重点是用nvidia的AI程序来进行视频的分析：
