Thanks for submitting this!
Thanks for suggesting Matt - will give it a go over the next couple of weeks (will probably have a couple of questions).

It seems like we may not have the option to make this work. According to this article:
Browser vendors have recently ruled that getUserMedia should only work on https: protocol. You'll need a SSL certificate for this API to work.
As an example, loading https://davidwalsh.name/demo/camera.php works within nOS because it's an https URL.
It looks like we can register a protocol as "secure" in electron. So in theory, we could change this line:
https://github.com/nos/client/blob/321dbf26928380bc0b6affb0aca70830f0a3c053/src/main/index.js#L19
to instead read:
protocol.registerStandardSchemes(['nos'], { secure: true });
The problem is that I don't think we can actually consider a secure scheme in a security sense. As far as I understand, the RPC servers aren't using Secure RPC, and many of the consensus nodes run on HTTP rather than HTTPS as well.
@deanpress I think we should opt to close this and #345 given the above, but I wanted to see what you think. Users will still be able to use getUserMedia
via HTTPS within the client as they can today.
A possible solution for content hosted coming from the nos
protocol would be to communicate with an IFRAME that's using the https
protocol via cross-origin communication.
Thanks for looking into this Matt, appreciate the notes, you saved me a lot of time.
From the messages, the suggested approach right now would be use an iframe and make the getusermedia() call within the iframe going to a https address. I will give that a go.
Probably worth considering a secure protocol (nos secure) in the future, with most public websites going to https by default now.

@mhuggins what about proxying the consensus servers with a https server? Similar to this https://github.com/be-neo/neo-https-proxy
@jeroenptrs Interesting idea. Where is this being used today? Would it integrate well with neon-js by chance?
Good old https proxy days hahaha amazing work @jeroenptrs 💪 we've used this on NeoBlog because IPFS requires a secure connection and the NEO nodes require a connection over HTTP. Due to this, we got a mixed content issue & Jeroen fixed it with this proxy module, to enable interactions with the IPFS nodes @mhuggins
If we can make this work with neon-js, then that might be a good short-term solution. The downside is that it's a centralized solution.
It seems like this is something that should be solved by NGD / added to NEO core long term. Any reason it shouldn't be that you guys know of?
If you start off http, it's gonna be hard to enforce https on every node. Especially since it requires reverse proxies and the whole #!, but NGD could force it on nodes... don't think they will though
Describe the solution you'd like and the expected behavior
Integrate Electron's desktopCapturer, documentation here: https://electronjs.org/docs/api/desktop-capturer.
Allow access to the users desktop audio and video with the following parameters supported (as described in documentation):
To capture both audio and video from the entire desktop the constraints passed to navigator.mediaDevices.getUserMedia must include chromeMediaSource: 'desktop', for both audio and video, but should not include a chromeMediaSourceId constraint.
Is your feature request related to a problem? Please describe.
Currently, a call to navigator.mediaDevices.getUserMedia() fails without an alternative.
