I'm looking at my options to control the Sonos Port at https://developer.sonos.com/reference/. I read about some UPnP control of other Sonos devices, but I can't seem to find any official information about this online. Is UPnP control of the Sonos Port possible?
Sonos uses UPnP for some calls internally, but we never publicly supported this protocol. We encourage you to use the Control API to control Sonos devices. See Connected Home: Get Started for details. Let us know if you see anything missing that you'd like us to add.
You can control any Sonos device via UPnP. The documentation for this used to be on the musicpartners site but access was exceedingly difficult. much of it is standard UPnP, documented at https://openconnectivity.org/developer/specifications/upnp-resources/upnp/ . There are many open source codebases that use it. It is much more powerful than the documented Cloud API in most regards.

I am implementing a camera device and thinking using WebRTC as the video/audio streaming protocol with the app. And I would like to stream the video/audio to Google Nest Hub. But from all the documents I can find, I didn't find any information that is related to WebRTC? So, I am curious if Google Nest Hub or Chromecast supports WebRTC or not? If yes, where can I find the related sample or document?
Google Nest Hub now supports WebRTC protocol. More information in regards to
this can be found here. Currently Chromecast does not support WebRTC, but we are constantly working on improving the capabilities of our ecosystem
I want to add video chat option in my website please guide me how i do this task and what should i required for doing this.How much it's cost if i will make it for my website and also it's maintenance(Like server ETC).
You are looking for something like rtchub.com
If you want it free, you can develop it yourself, using WebRTC:
WebRTC is a free, open project that provides browsers and mobile
applications with Real-Time Communications (RTC) capabilities via
simple APIs. The WebRTC components have been optimized to best serve
this purpose.
See WebRTC Tutorial
On client side you use JavaScript (jQuery), and clients communication directly using browser, but you need server part and signaling mechanism, and you can use for example SignalR or Node.js.
As example you can look at my site: SignalRTC.
P.S. WebRTC works only on selected browsers, for example Chrome, FireFox, unfortunately not on IE or Edge.
I have some questions like how whatsapp server is working, though I read in internet, I want to understand much. And what is XMPP? how it is working, How can I send data through XMPP. how can I integrate XMPP with application, can anyone pls explain?
WhatsApp under the hood?
There are rumors WhatsApp uses a customized version of XMPP. Sources are closed so we can only guess.
Understanding XMPP will however give you all the tools to create your own WhatsApp clone.
What is XMPP?
According to Wikipedia (which hosts further references):
Extensible Messaging and Presence Protocol (XMPP) is a communications protocol for message-oriented middleware based on XML (Extensible Markup Language).
Which is to say that XMPP is an xml based convention for exchanging messages between parties. It's best known implementation is Ejabberd chat server.
XMPP can however be used for other things, among them the web of things.
How to send messages?
Assuming you want to create a chat application, you will need:
An Ejjaberd server up and running.
An appropriate xmpp SDK for you language/framework. Example: Smack for Java or agsXMPP for C#.
A good kick-starting tutorial about how xmpp works can he found here: part one and part two.
There is also the RFC which contains the most comprehensive documentation out there.
As stated in the Google Talk for Developers site, you can use the provided APIs to build a client that connects to the Google Talk service.
I would like to know if it's possible (or it will be in the near future) to build a similar client to the google hangouts.
What we pretend is to build something similar to cloud print, that provides printing services to the cloud, but for audio/video streaming: a camera and microphone would replace the
printer.
Thanks a lot.
Talk and all the XMPP stuff is going to be put down soon.
The new Hangouts infrastructure is proprietary. It only has API to integrate Hangouts into web pages and applications, but no API or protocol to create an alternative Hangouts client software.
https://github.com/tdryer/hangups is a library that does exactly that, with a command-line client for Linux.
https://github.com/xmikos/qhangups is a PyQt-based cross-platform app that aims to provide an open-source alternative to the Chrome-based official desktop app. Unfortunately it's not working at the time of posting, but the author is investigating the issue.
Are there any initiatives to implement/agree upon a standard API for connectivity between web browsers and client hardware.
Example: The iPhone has a GPS/Camera/Accellerometer in it. It'd be very cool if my web app could communicate with them (rather than me having to write a thick ObjectiveC application).
The closest thing I've seen to that is the Android phone API, which lets your programs access its hardware (relatively) painlessly. Google's pushing for it to become the new standard, but its hardly the same thing as a web-app (which, by most definitions, runs entirely in your browser?).
The upcoming version of FireFox has an API to read your lat/long off a GPS device.
To add to my own question; Yahoo provides a geolocation service called FireEagle that could act as a mediator and provide similar functionality.
In essence the phone communicates with a central Yahoo server updating its location. Your web app can then determine your approx location from that central server.
