Make android phone as USB Webcam I have an Android tablet based on Android Lollipop (5.1.1) and I want to use this device as a webcam via USB.

I know some apps could work (e.g. DroidCam or WO WebCam) but they require extra clients installed on a Windows / Linux computer. 

Is there any way that I can add an extra option to the USB connection settings that will allow the tablet to be used as a webcam instead of a media device?

Please note I am not asking for apps that can read videos from OTG USB webcams. It's the reverse, making Android output a video feed to a separate computer via USB.
Driodcam works fine for mine Lenovo tablet- skype and all video programs now recognize it as camera, therwise, i havent found anything that works, tried vysor, but that didnt work....
