Darknet: How to connect a camera through rstp

[Ludwigromanam]

Hi everyone,

I am trying to connect a drone's camera using rstp and use YOLO for object recognition. I have been trying to find out what files and lines of code to change in order for me to achieve my goal, I have tried changing, the art.c and demo.c files but nothing works.

Does someone here knows what lines and files I should change ?

Thanks to all in advance !

I use in this way: ./darknet detector demo cfg/voc.data cfg/yolo-voc.cfg yolo-voc.weights rtsp://login:[email protected]:554 -i 0

@AlexeyAB Hi, it works with rtsp stream, but with 3 seconds of delay. Do you have any idea to solve this problem? Thanks in advance.

Try to use this command: https://stackoverflow.com/questions/20613453/warning-could-not-find-codec-parameters-modules-highgui-src-cap-ffmpeg-i
./darknet detector demo cfg/voc.data cfg/yolo-voc.cfg yolo-voc.weights rtsp://login:[email protected]:554?dummy=param.mjpg

Also can you see this rtsp-stream by using VLC video player or other soft?
