补充材料
/dev/video1~3 are the three channels output by the camera. The AI uses /dev/video1 and /dev/video2. If you want to run the AI demo and rtsp stream simultaneously, the streaming needs to use /dev/video3.
ffmpeg -f v4l2 -input_format nv12 -r 30 -s 1920x1080 -i /dev/video3 -c:v h264_v4l2m2m -b:v 2M -vsync passthrough -f rtsp -rtsp_transport tcp rtsp://<your-rtsp-server-address>/*
