I need to create a broadcast video from the server to many clients
In server i use https://airensoft.gitbook.io/ovenmediaengine/
When connecting for the web, I use
"file": "ws://3.123.0.22:3333/app/test_o",
"type": "webrtc"
please tell me
how to implement the same thing on nativescript
Thanks for posting a question about OvenMediaEngine.
First of all, we've never used NativeScript, so it's difficult to give an accurate guide, but I'll let you know what we understand as much as possible.
1.
The easiest way to play WebRTC with NativeScript is by adding a WebView and playing it inside.
Please refer to this page (click), add a WebView to your project, then create a page that can load OvenPlayer in that WebView.
2.
Another way is to install a plugin. Click HERE to install this plugin on your project and connect the OvneMediaEegine Signalling to be able to stream with WebRTC.
Please see to our guide (click), interlock Signalling with WebSocket, get the SDP of OvenMediaEngine, and put it in WebRTC plugin.
Thank you!

I'm trying to stream a microphone/audio to multiple clients.
the broadcaster is a screenless raspberry, so I can't open a Webbrowser and click on "share mircophone"
The clients will be using their smartphone to listen.
the latency must be super low.
I did not find any WebRTC Demo that worked. All of them are either p2p or the scalable Broadcasting from muaz khan is only working for the initiator; not clients.
I came across Janus (which I didn't really understand what exactly this is doing) but I don't get how to install this and how to configure it.
Is there any way to easily share the microphone's output via WebRTC? Something like Apache hosting a simple website where the microphone audio is hosted on?
Thanks for all the ideas on how to solve it!

No. There's nothing easy or simple about WebRTC.

This is the simplest option... running a browser. Are you sure you need to actually allow it to access the audio device?
In the past, I've used a flag on Chromium to get around this problem. I don't remember exactly what that flag was, but looking at the list, it might have been...
--use-fake-ui-for-media-stream
You might also be able to use --enable-kiosk-mode.
At a minimum, if you were to open the browser interactively and enable access, that page would get automatic access in the future.

WebRTC is peer-to-peer, but remember that the "server" can be one of those "peers".
Finally, you can look into using GStreamer, but don't expect anything quick and easy. https://github.com/centricular/gstwebrtc-demos
My team is familiar with Java and we don't have much time to learn "nodejs" and the related "express" framework. We really want to use react-native to develop some application.
I'm frustrated, since I don't know whether I can use react-native with Java and an Apache Tomcat Backend.
If it is possible, what should I do to make it work?
If not, how do make it possible? By using node as the request dispatcher?
Any ideas are appreciated!
Sure you can! React Native is a backend-agnostic technology. Just write your backend in any way you want and expose an API that can be consumed by your application!
For communication with your backend you can use "fetch", "websocket" or "xmlhttprequest". You can find more information and examples in the official documentation: https://facebook.github.io/react-native/docs/network.html
I am building a video chat website using OpenTok. I have the video and text chat working, (still working on the screen sharing), but I was wondering if anyone could point me in the right direction regarding file sharing?
I would like both parties to be able to send files to each other, but not really sure how to go about it. Would it be possible to use Peer5?
There are several ways to get the peers to send files to each other.
A first way is to upload the file to your server or to some cloud storage service. Then share the link to the other peers via OpenTok's Signaling API (which is, presumably, an abstraction over WebRTC's DataChannels). This solution is simple, but not peer-to-peer.
Another solution is to, again, upload the file to a server and share the link to the other peers, but this time have the peers download the file via Peer5's Downloader. The Peer5 Downloader uses a coordination server to figure out which peers are available to help with the download. If no peers are available, the download will fall back to the HTTP server. This of course only makes sense if the file is being shared with several peers at the same time. In 1-to-1 communications it is pointless.
The previous solution is P2P only in the download part; the user still has to upload the file to a server. Another way, which would be P2P all the way, is to cut the file into chunks, and send them over the OpenTok Signaling API. It is a complicated process but there are several tutorials about this. The tutorials use the WebRTC DataChannel, but it is reasonable to assume that they could be adapted to the Signaling API:
https://bloggeek.me/send-file-webrtc-data-api/
http://www.html5rocks.com/en/tutorials/webrtc/datachannels/#build-a-file-sharing-application
A interesting open source application of a file sharing app using WebRTC is Sharefest, made by the guys from Peer5. You can use it for inspiration if you are inclined to make such a system.
As a side note, OpenTok seems to be considering to build a starter kit with sample code about how to integrate OpenTok with Peer5 in a file sharing application. I do not know how such an implementation will work, but I presume it is some variation of my second suggestion here. It could be good to keep an eye on it.
Background: I've a sensor hooked up to an arduino printing readings through the serial monitor. I want to log these in firebase.
I've done a bit of digging on this, and my research has shown me that an arduino simply can't handle the SSL needed to talk to firebase properly.
Any suggestions for workarounds? Checking SO and google's only turned up "it can't be done", but I figured I'd ask anyway. Any lateral thinking is appreciated, thanks!
If you figure out a way, let us (support#firebase.com) know. That would be an awesome hack!
Some thoughts:
You might want to look into the Spark Core (available for pre-order). They mention SSL support, though it's unclear to me what that means exactly.
You could proxy the requests through a server that can speak SSL. For instance, you could run a tiny node.js service on an Amazon EC2 box that just proxies REST requests to Firebase (e.g. using http-proxy).
If you're hardcore, you could try to get the Arduino talking to an external ethernet controller that has built-in SSL support (e.g. this one), but that's probably a big project. :-)
Longer-term, we might expose a non-SSL endpoint for Firebase requests that's specifically for this sort of low-end hardware use-case. Ping us at support#firebase.com if you want to start a dialog.
Here's a php script I whipped together to solve for Arduino no https.
It's basically a form that GETs to the php script and then sends it off to your Firebase database.
http->php->Firebase

*Make sure you add Heroku or your server to the whitelist of IPs that can post to Firebase
I know its an old question but visitors from google keep coming.
Have a look at this post: http://www.devacron.com/arduino-firebase/
[EDITED]
These arduino libraries might help:
firebase-arduino
https://github.com/googlesamples/firebase-arduino
https://github.com/ed7coyne/firebase-arduino
To install it:
Download the zip file, go to Sketch>Manage Libraries>add .zip file
Now you have access to
#include <FirebaseArduino.h>
and can begin using it with
Firebase.begin("example.firebaseio.com", "token_or_secret");
Follow the example at https://github.com/ed7coyne/firebase-arduino/blob/master/examples/FirebaseDemo_ESP8266/FirebaseDemo_ESP8266.ino
I would like to receive remote push notification when the app is on the foreground. I think I can use "didReceiveRemoteNotification" in Objective-C, but how about in Titanium? I've been searching solutions but can't find anything. Does anybody help me out?
Titanium currently only supports local notifications (by default) I believe. You might want to take a look at AppCelerator as a solution.
Sorry, i was wrong last time. It's very hard to find but Titanium supports a way of interacting with PushNotifications.
Please take a look at Ti.Network.registerForPushNotifications. It provides a callback that is executed when you receive a Push Notification.
The other posted solutions below may provide a better integration for titanium so it's up to you what you want to use. But this should answer your original question.
Unfortunately Titanium only supports local notifications on iOS. If
you want to support remote notifications you can use
Urban Airship
ACS (Appcelerator Cloud Services) or
you write your own module that provides "didReceiveRemoteNotifcation" as an app event to your app
As far as i know you can only listen on local notifications by
default but you can try this method if it reacts on remote
notifications..
