Quickblox Sample webrtc video chat not working - html5-video

I'm trying to implement a webRTC based video chat example. I've taken a look at Quickblox and their solution. In particular, I've given their online demo a test run: http://quickblox.github.io/sample-webrtc-web/
I've opened two tabs in Chrome logged in as different users. It does not seem to work. Does this work for anyone else? Besides that, it looks like a great solution to what I'm trying to achieve so I'm hoping it is just a wrong setting with my computer.
P.S. I can see the local video stream (i.e. my own face staring back at me in the mini view, but the place where I should be able to see the remote user is black).

Send real-time video via wifiSend

I would like to make a personal application to be installed on two iPhones. The first to be used as a webcam that transmits to the second via wifi.
Having no experience with xCode, I am looking for a code example to connect 2 devices via wifi and transmit a real-time video stream.
Unfortunately, the documentation and examples I found are deprecated or partial and inconsistent.
Where can I find some code examples to help me solve my problem, preferably in ObjectiveC (but also in Swift)?
Thank you

Webrtc to remotely control phone camera

I am looking for help to take still photos remotely using webrtc. Is there an API that allows access to the other person's rear camera (with permissions) to take photos and save them to my phone? The idea is to use this to take full resolution photos with Android and iOS using react.
Yes you can do this by let them join a channel and then you can send request from your side to ask camera to take picture and then send you back. This is just like message. You sending message from your side to ask other person for taking picture although. If he is using browser then it can be done using js for getting permissions. But in case of a mobile application you can have your own endpoints to interact with channels. I hope you got the basic idea.

I don't want camera permission needed for each video chat when there is a series of 1-1 video chats at an event

I am not a coder and having a web platform built with PHP that includes a series of 1-1 video chats in a scheduled networking "event". The problem that the developer is not able to solve with the video plug in that they are using (https://www.magnoliyan.com/video-chat-pro/) is that the user needs to give camera permisson before each chat. I need this permisson to happen one time only at the beginning of the event and not need there to be any further permission giving throughout the event. Of course I would like this to work on all platforms. I'm exploring agora.io as an option to solve this and replace the current plug in with agora. Does anyone know if agora would be the right fit for this or which video chat platform I should use to accomplish this? And if there is specific developer kind of language or code - please speak in as if I was a developer and I will pass on what you say to him directly. You don't need to worry about whether I will understand it.
Thanks!

Agora.io like any other WebRTC provider requests device camera permission only once. And all subsequent Videocall won't need any special permission (provided that they are on the same domain)
More specifically, Agora.io requests browser permission when stream.init method is invoked. This also turns on the camera light. stream.close turns off the camera light and deallocates the resources.
However, the subsequent stream.init function calls do not require permissions. (Camera light will just turn on)

Sencha touch 2.0, android app keeps showing loading screen forever on certain devices

I've finished writing my first Sencha app and released it in Android market place. This is basically for a conference being held in Metro Detroit Area next week. I'm also introducing Sencha in my company as a viable mobile option.
However once released into the market, it does not seem to load on certain devices. How to find out what is wrong on the device? It works great on desk top and also on certain android phones and nexus pad but does not load ( the user keeps seeing the loading page for ever) in certain other phones. I would like to know how to debug this issue? Does Sencha log the console log exceptions in logcat? Any help in this direction is highly
appreciated!
I'm using Internet permissions to access twitter feed and google maps. Kind of guessing that the issue could be because of accessing Internet but how to find that out?
Thanks
From experience, this is generally due to javascript errors before sencha has been properly set up. This can be missing functionality or include issues, picky parsers etc. There is no real good way to debug this more than to get ahold of an affected device and set window.error = alert before any other javascript is run.
