一、test-launch 推流
1、查询所需的库文件
pkg-config --cflags --libs gstreamer-rtsp-server-1.0 gstreamer-1.0

2、拷贝gst-rtsp-server-discontinued-for-monorepo-1-19-2.tar.gz到rk3588开发板编译：
#gcc test-launch.c -o test-launch pkg-config --cflags --libs gstreamer-1.0 gstreamer-rtsp-server-1.0

3、在开发板上输入命令
root@lubancat:/media/gst-rtsp-server/examples# ./test-launch --gst-debug-level=3 “( v4l2src device=/dev/video-camera0 ! videoconvert! videoscale ! video/x-raw, format=(string)NV12, width=1920, height=1080, framerate=30/1 ! queue ! x264enc bitrate=2048 ! rtph264pay name=pay0 pt=96 )”
