Power Up Your CV Projects: Real-Time Camera and Video Streaming with OpenCV and Sockets

[@adino117]

For those of you using a raspberry pi + raspberry pi camera as your client: In the server code, instead of s.bind((ip, port)) instead use s.bind(('', port)) ^ (that is two single apostrophes not one double apostrophe) Great video Nicolai thanks

[@NicolaiAI]

Awesome, Thanks for posting!

[@borisikula4639]

I wanna know if it is possible to use this technology for a c++ client and a opencv server? Can someone help me to have quickly an answer. Thank you Nicolai

I'm trying to use this approach but I can't send images larger than 65kB even if I set the RCV and SND buffer like the video. Any idea?

[@Techiiot]

Does this streaming work without active internet connection

[@NicolaiAI]

Yeah this is running on local host right now

[@mohammadhaadiakhter2869]

I have a Jetson Nano which I am using as client and I have provided it internet connectivity via ethernet cable from my Ubuntu Pc using ethernet cable and internet sharing. I want to use my Ubuntu PC as Server.Ubuntu is connected to internet via wifi. What are the ip-addresses I should put in client and in server?

[@mohammadhaadiakhter2869]

Got it

[@hosamfakher]

how can get the full resolution of camera my camera is 12 mg pixel ( 4000,3000) opencv resolution is 1920 1080 or 1600 1400

[@NicolaiAI]

U Can set that in the capture settings as i do in this video

[@hosamfakher]

@@NicolaiAI i put it but camera is black

[@NicolaiAI]

Does it work wothout the sockets when u just show it?

[@hosamfakher]

@@NicolaiAI iam using raspberry pi 4

[@kajinguludan5886]

I am using a Hikvision camera and when i run a computer vision program on it, after a few minutes, the stream just stops, i dont want the stream to stop, how can i solve that?

[@NicolaiAI]

Do u have memory leaks or something or lose connection?

[@kajinguludan5886]

@NicolaiAI no memory leaks that I am aware of but no loses, it just closes and I have to click again to reopen the feed

[@riis08]

is there any video where we can send h264 images stream?

[@NicolaiAI]

Im not sure that is supported by imencode. U could use the video writer for that. But if u want to have a stream running u might have to look into ffmpeg and then use the sockets as in this video

[@SouravDas-bw9wc]

This application can stream live audio with this video ?

[@itgoons]

is there is any way i can do it for 1000's of viewers? and how it will be possible

[@nguyencongtri2839]

why waitkey(5) instead of waitkey(0)

[@032525016]

waitkey(0) will wait for the user to press key indefinitely while waitkey(5) will wait only 5 milliseconds for the user to respond. If user doesn't respond, the execution of program will continue but if you want to read the video frame by frame on key press then set waitkey(0)

[@NicolaiAI]

Thanks for answering luka!
