USE JAVASCRIPT-SDK IN NODE-RED
is it possible use object detection in node-red ????
can you send source code for check ?
Yes it’s possible. In what way would you like to use it in node red?
I have a demo that uses node red, but it’s mainly for streaming video from a raspberry pi or drone and doing detections on that. It might not be too useful for you
Here’s a video that goes over object detection with node red https://youtu.be/h_-wTXlX2Ms
It doesn’t actually do the actual object detection in a node red node though. It still does it in the browser so you can get real-time predictions. However it shouldn’t be too difficult to make a node red node that does detections. You wouldn’t be able to use this sdk though because it only works in the browser. You need to do it using TensorFlowjs-node
hello @bourdakos1
i want to get video from ip camera with ffmpge and rtsp address .
after that object detecting on video.
i think in node-red i can do it easier .
my Big problem is get rtsp video from ip camera in web browser for using javascript sdk and object detection do you have a solution for it ????
@bourdakos1
ip camera has an address like this for get video rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0
for test react object detection app with ip camera we have to use rtsp address but i cant find easy solution for this ,
i test this solution i made a node js app that use socket.io for send video to client and
But in client side (react app) i dont know how show video(get video) in react app with this code import * as io from 'socket.io-client'
can you help for this ? or better solution
okay, so I think you'll need to use ffmpeg to restream rtsp as HLS and then this might be useful: https://github.com/cloud-annotations/object-detection-live-stream
Actually this is probably more useful https://github.com/cloud-annotations/raspberrypi-streaming-object-detection
@bourdakos1 thanks for helping this is many rtsp link that you can test
rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov
rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa
rtsp://freja.hiof.no:1935/rtplive/definst/hessdalen03.stream
thank you man my problem is to get video from rtsp address in react app for object detection .
Okay, I think I have something working! It works with all 3 of these addresses
https://github.com/cloud-annotations/ip-camera-object-detection
change the STREAM_URL to your url
npm install
npm start
@bourdakos1 This code works for rtsp address i tested it , Thank you very much and thank you for your help ,
i have another question , how use this code without internet (offline) can i load this link locally ??
yea just download this file: https://cdn.jsdelivr.net/npm/@cloud-annotations/[email protected]
and save it locally as models.js in the js
then update the script tag to be:
<script src="js/models.js"></script>
@bourdakos1
i tested it works thank you ,
another question is it possible have two video on same page for object detection ???
two rtsp address link for two camera i mean .
yea, it's possible, but running more that one object detection detector simultaneously will probably be slow
i have goood pc for test it .
can you send code for two object detection ???
I don't have code for it and I don't really have much time this week to build it.
You could modify the ip-camera code to have dynamic stream routes instead of one /stream
@bourdakos1
it is not hurry for make code , you helped me very much
i dont know very ffmpeg in nodejs
can you send me link for learning it ????
i need two object detection(rtsp address) on same page ,
