Streming local web cam

Hi, sorry me but not find need subject. In my project need implement stream from local (usb) web camera, this camera directly connected with server. Maybe have solution for this?. In OpenVIDU have api for connect rtsp cam, maybe need expand them, for exampel “localCam”. Gs Streamer have all for this.

Your question little bit confusing please explain it properly.
Thanks
