https://github.com/umlaeute/v4l2loopback/ could be used for the webcam thing

there is an app on the android play store ip webcam and i have used this and it works. All you have to do is open the url of the phone with the port in either the browser or in the supported driver which adds the phone as a camera to be used in any application.
How i see it, we can open the "share camera on device" button and clicking it, the camera would show up allowing us to change cameras and flash and other things. On the other side, like on desktop, the driver would via kde connect recognise the camera saying "hey. you now have a new camera up, if you havent installed the driver, do it here". then we would open say skype and select the camera source to kde connect-phone1 and thats it.

hello, i am a recent user of kde connect. And, it's awesome and smooth experience.
i am a also who have interest in implementing this feature.
can you all tell me where i can start or which direction i should look to implement it in kde connect ?

First make sure to start working on one of the 3 listed. I guess it depends on which you prefer we can start looking into.

i am assuming @apol you are asking from three WiFi ,Bluetooth and cellular data. i think WiFi will be right choice to work with first.
also if you are asking for camera or mic, first i would like work with camera part.

No. I meant the camera, microphone and gps.

So like Nico said above, you'll need to look into creating a v4l2 device on the linux side, maybe through loopback.
