I'm sick of opening hangouts and automatically start broadcasting my webcam, that is the most annoying feature, seriously google developers must be on shrooms because nobody likes that.
Ideally I would like to block it completely and allow it occasionally to hangouts.
So I found online some tutorial where it explained "how to do it" but it doesn't work.
I went to Settings -> Content Settings -> Media

As you can see i cannot edit that, it only allows me to block or allow them at the same time, i cannot block only the webcam.
So, I'm starting to wonder if i could just "pull a switch" on my ubuntu through the terminal or something to enable/disable the webcam outside chrome?
Also tried going into the adobe flash settings and even after spending half an hour going through hundreds of websites inside a little box of 4 lines (how is this company so rich?) I can't even find google, besides if i did i still couldn't find the option to block only the webcam.

I use skype all the time to chat with friends and family and I use my webcam, its annoying to have to take out the tape and put it back 3 times/day.
So, is there anything I can do besides adding actual duck tape to my precious notebook webcam?
Edit: Yes, I added the ubuntu tag because one solution would be to disable the webcam completely on ubuntu (you can see i suggested it on the question) and enable it only when I'm going to use it, that way I don't have to use tape over my webcam, it looks gross, its time consuming and it's what i'm trying to avoid.
