You did get the message that that kind of drivers are (usually) written in C++, and not in C#, right ?
I don't get quite clear where the output of your webcam should end up, into Skype so you can view it remotely? All webcams I've seen (not that many though) offer some kind of software to watch remotely what's going on, what isn't good enough about that?
Or is it just another programming challenge you're after? For that itch we have NANY 2016, here at DC
Yes, I do understand that drivers are written in c++ and I have programmed in the language many moons ago and believe I can pick that bike up and start writing it again.
I believe webcamming should be a fun, interactive experience. Fully of flashy features and the ability to paste graphics and interfacing with with actual, live data. Let's say for example you do a google hangout with supporters of your project and you want the amount of currently donated campaign funds as a banner on your webcam that updates in real time. Manycam can not do this, but OBS can. As far as I know, there is no custom support to stream from OBS to google hangouts, and if there is, well, it's probably difficult for a novice. Selecting OBS as your webcam would alleviate such a problem. A one-click solution. My philosophy for creating programs is "see a need, fill a need", and I believe this would be something I would use on a regular basis and someone else out there might enjoy if they knew it existed.
... also yes this is one of my few NANY ideas, you caught me
