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:pass@192.168.0.228:554 -i 0

Thanks a million @AlexeyAB ! I will give it a try !

@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:pass@192.168.0.228:554?dummy=param.mjpg

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

I am having the same issue, have u fixed?

From the iSpy or Agent (https://www.ispyconnect.com/man.aspx?n=Ip+Webcam+(android)), we can see that the IP webcam for android does not support rstp protocol, only support for http protocol. And IP webcam pro support for rstp, the suggested URL format is: http://ip:port/11

Hello, how do I connect to the HoloLens2 cam?

[ExpiredTapWater]

Hello, I'm having an issue connecting an RTSP camera. I'm able to view the stream on another software like VLC, but I keep getting "video-stream stopped". I tried thisdarknet.exe detector demo cfg/coco.data cfg/yolov4.cfg yolov4.weights rtsp://username:password@192.168.1.10:554/stream1 -i 0 and all of the other variations here but I could not get it to stream. Could anybody point me in the right direction?

Im getting the exact same issue as you and done the exact steps and still nothing. Did you manage to find a way?

Hello, I am facing this problem, and from what I have searched it's caused by multithreading. But since I am pretty new to cv and yolov7 could you help me out on this? How and where should I change to code for it to work as it should? [[h264 @ 0x8f915e0] error while decoding MB 53 20, bytestream -7],

I am using yolov7 on ubuntu 20.04, proc i5, rtx 3060ti

Hello everyone Iam trying to run the yolov4 object detection algorithm in my drone camera,in my jetson xavier. In yolo files iam exactly trying to figure out where the rtsp stream is displayed in my screen but nothing helps,I excatly need to restream that stream to another screen

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

Have a good day! Thanks to all in advance !
