Different Google Cast devices

[romaincointepas]

Right now it seems that this library will show all Google Cast devices that have device.manufacturer = "Google Inc.".

• There are many different Google-made Google Cast devices out there, some of them being audio-only (like the Chromecast Audio, Google Home, Nexus Player).
• There are many different Google Cast audio-only compatible speakers out there.
• There are many Android TV (so Google Cast video/audio-compatible) TVs and TV Boxes out there (Sony Bravia, Sharp AQUOS, NVIDIA Shield, etc.).

As far as I know, the only way to know at discovery time if a Google Cast-compatible device (including Google's own devices) is audio-only is by matching the device.manufacturer and/or device. modelName to a list (I've pasted below the SSDP response for Google Home that is audio-only).

I'm also wondering if all Google Cast compatible devices (ex: NVIDIA Shield, Sony Bravia, etc.) will answer with device.manufacturer = "Google Inc." (I'm assuming they don't).

It would be great if this library could also returns device.modelName as a property, and potentially add an option to not filter Google Inc. as manufacturer and returns device.manufacturer as well so anyone with a more advanced use-case (and time on its hand) could offer a better experience.

Something that could be cool would be a property audioOnly that is true if we're sure it's an audio-only device, otherwise false (and a comprehensive list could be maintained in the lib, starting with the obvious Chromecast Audio and Google Home).

While I'm not sure I'm the right person for a PR, I'm definitely open to report back on any manufacturer/modelName I encounter in the wild. Maybe the folks at webtorrent-desktop knows more about this (@feross, @dcposch).

I've also find this if it helps:

I think that this idea makes a lot of sense.

I have a Chromecast Audio that I can test the audioOnly feature on, if you (or someone else) wants to send a PR.
