I want to do real-time web streaming with jetson nano board and raspicam2 so that many people can access it at the same time
Can you tell me the related technology? I want you to tell me the server technology as well.
thanks

I'm trying to help this open radio station guys: radioqk.org. However I'm quite new about the topic of streaming and radio servers. I'm quite surprised that all what I found is about a desktop software clients (eg. Sam broadcaster, Butt, Radittcast, DarkSnow...). However they are confusing to configure. So we are trying to embed it on their website to make it easier to stream from any part of the World to any stream server (eg. giss.tv, caster.fm, listen2myradio.com...)
I have read that it's not possible at the moment, because there is no way to make a streaming HTTP PUT request.
However, if I have understood well, it is possible with liquidsoap.fm because its server support the webcast.js protocol, using the following code: https://github.com/webcast/webcaster
On the other hand, I have search php code able to record from microphone to store it on the server. Or maybe it's about HTML5 and its new function getUserMedia()? It seems it was difficult a few months ago, but now it is possible so:
Is there any live-streaming service with the client integrated so it can record from the user's computer microphone / sound card? I mean, is there a similar service like giss.tv able to record from the user's computer microphone / sound card?
If I'm right, IceCast is the most common opensource implementation of radio streaming. Is there any implementation of IceCast able to record from the user's computer microphone / sound card?
By the way, the idea is integrating it in a WordPress server. That's why I have based the search on PHP (I have not found a WordPress plugin able to solve this problem). However it could be done in another language / server to embed it into WordPress afterwards.
Finally, a workaround could be the following article that talk about including on the website a hyperlink to a Java-coded VNC viewer to take a desktop application to the web in 15 Minutes. In the VNC server side would be any of the desktop software available we have talk about above.
Any light about this topic? I'm quite confused about what path I should take...
I have read that it's not possible at the moment, because there is no way to make a streaming HTTP PUT request.
That's correct. In the very near future we'll have Streams support in the Fetch API, which gets around this issue. In the mean time, it isn't possible directly.
As I mentioned in the post you linked to, you can use a binary websocket connection. That's what the Liquidsoap webcast.js uses... a binary web socket, and a server that supports it. Liquidsoap supports their own protocol, so you can use this to then stream to a server like Icecast.
Is there any live-streaming service with the client integrated so it can record from the user's computer microphone / sound card?
I run the AudioPump Web Encoder, which acts as a go-between for web based clients and your servers. The web-based client can be configured in the URL, so the users don't need to do anything. This might meet your needs.
If I'm right, IceCast is the most common opensource implementation of radio streaming. Is there any implementation of IceCast able to record from the user's computer microphone / sound card?
Yes, Icecast is a popular open source server. But, the server itself cannot and should not be what is recording the audio. You wouldn't want to run the server in the same place as you're doing the encoding... otherwise you'd need all your bandwidth there. The encoder is separate from the server so that you can encode in one place, upload one stream, and then the server distribute it to thousands.
Im making an app that multiple players can connect to, but im brainstorming the best approach.
Im going to be using electron for the interface and then be able to use other computers to log in to website to join the game with multiple players.
I will use sockets to connect to each player, but what i am trying to figure out is whats the best approach for the interface.
Should i use express with electron to somehow connect to the same website the players are on?
Is it possible to make the electron app start up a server and have my website direct to the computer that is running the electron app?
Or my other option was to just continuously upload and download from a database, but I feel like that would not be very efficient.
You're on the right track. I would suggest using a WebSocket based server / client architecture.
The server application is continuously running and handles inter-player communication as well as providing a database. The database could be integrated in the server application as a starting point, and, depending on your needs concerning scalability, be extracted as a standalone service in the long run.
Client applications could then come in many forms (a website, a desktop application, a mobile app). Using electron is a great way to enable cross-platform desktop application development that is adaptable to any of these scenarios, possibly also enabling to extract the contained web application as either a hosted website or even mobile application (using, for example, react-native or nativescript).
Good luck!
Must a game be client server which then requires me to stand up a server? If so, can I do that on a web host? Azure? ..
If not, then how do the 2 window phone clients find each other?
I am having difficulty understand the main blocks invovled in doing this and how they come together...
What about bluetooth ? From what I have read so far there is no access to the bluetooth api ?
Is there or wil lthere be any helpers from xbox live and thier api to let a indie dev set up connections ?
There are 2 options for creating a real time multiplayer game.
Devices connect over the internet or used a web based mediator to relay game data.
Devices connet via sockets over UDP.
If you choose option 1 then you can host your web based component anywhere.
If you choose 2 then there is a sample that may be of interest at http://msdn.microsoft.com/en-us/library/ff431744(v=vs.92).aspx
There is, currently, no support for working with BlueTooth in the API.
I see that Game Kit allows you to develop games with voice chat.
I want to build a more general, peer-to-peer voice chat application, that does not have to live in the Game Center. So a couple questions:
1. What peer to peer system/technologies could be used for this?
2. If I wanted to allow voice chat with a Flash client (i.e. iPhone app <--> Server <---> Flash client on PC) would options for 1 work for this?
I have some experience with RTFMP for Flash to Flash client chat, and no iPhone dev experience, so just want to test out some ideas.
Maybe one idea: build using the Ribbit Platform - they have both Objective-C and Flash SDKs, but this looks more like traditional\SIP calling.
Anyway, would appreciate anything that points me in the right direction.
Thanks.
Now that flash has access to raw Microphone data, you could roll your own client and server; yet, since, currently, it doesn't have UDP sockets in AIR for mobile, you would be forced into considering audio quality vs lagg with even tighter restrictions then usual.
You can now roll your own native extension to make this work; yet, I am assuming you want something that only requires coding in AS3.
Therefore, considering your restrictions, the only real bet would be to use Flash's built-in communications capabilities (e.g. RTMP).
With the above being said, there are opensource alternatives to the array of Adobe's own flash communication servers:
the red5 server, and rtmpd.
IMHO Ribbit's services are kind of pointless.
I want to create a playstation home style multiplayer game for iphone. How can I implement multiplayer in my project? Also, how can I give players a chance to chat? How can I let them create their own avatars to interact? I am a one man developer, with no access to servers. Maybe I can use iPhone game centre???
If you're looking for some kind of platform to build on, there is a product called SmartFoxServer:
http://www.smartfoxserver.com/
I have not used it, but it claims to provide a client API for native Obj-C or Unity3D. It allows for chat features.
If you want to roll your own, I recommend getting started with NodeJS:
http://nodejs.org/
GameCenter does not provide any kind of backend for multiplayer networking, at least not in the way you are implying. If you intend to build a networked multiplayer game over the internet, you most likely need some kind of backend.
Slicehost is a good way of getting a server like NodeJS running quickly and cheaply:

Don't forget that GameKit in iOS allows multiple devices to find each other locally (via Bluetooth or local Wifi) and create sessions. This might be a good starting point for your game. Here's some info on GameKit:
http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/GameKit_Guide/Introduction/Introduction.html
I think this would usually be done with webservice interaction against a server. You may be able to develop a webservice and pay a small fee to have it hosted by a web provider, or to use your own machine as (an unreliable) server while proving the concept.
Or you could just use Nextpeer - http://www.nextpeer.com
It makes adding online tournaments to your game real simple.
You can look at Gamooga (http://www.gamooga.com/).
Its a realtime communication platform for multiplayer games so you dont need to worry about building and deploying your own multiplayer servers. You can upload your own server side scripts onto Gamooga's cluster which receive and process your clients' messages. You can use Gamooga's iOS API with in your app to send messages from the client side to your server side scripts. You can download the SDK and look at the demos to start off.
There is a free plan of Gamooga platform too that you can make use of to start with.
