Live Video Chat for iPhone and HTTP Live Streaming

So generally, I want to make an app which has video chat functionality for iPhone. But after many searches, I am still not able to find any successful results. Is there any public or even for that matter, private API available for doing this on iPhone??? If you have an YES answer, please help me.
Basically, what I want is to read the streams of the video on both the devices connected for chatting. Thanks a lot in advance and please help me if you can.
p.s - I have already checked iDoubs but it failed and always shows some unknown problem and for that reason, doesn't allow me to connect to anyone.
ALSO : The suggested method I have found is via HTTP Live Streaming. But, in that too, I have multiple doubts.
1.) I need to find how do I upload my video from iPhone to the HTTP server from where I would be broadcasting?
2.) Can you please post something related to setting up the server? How do I feed the video to the FFMPEG Server?
Mainly, I need to find the upload method. I am right now simply sending hex-code in the form of NSDATA to the server and I am stuck there. The main problem is, It is live. How do I handle that?
It would be best, if you could help me make the iDoubs work properly.
Thank you so much for any kind of support!
have a look on this how to implement video chat in iphone But before starting you must have a IMS server up & running.
here is the live video chat framework what you are looking for. Its easy and simple to implement for face to face video chat. I have already tried this. Its working very fine. Great thing about this framework is multiple platform support.

Sample Code:

Edit:
Here is the article explaining opentok using parse.
http://www.iphonegamezone.net/ios-tutorial-create-iphone-video-chat-app-using-parse-and-opentok-tokbox/
HTTP live streaming is primarily an approach for adaptive streaming from server-to-client. For client-to-server rather go for traditional streaming. There exists an open library for streaming, see this question.
Whilst it is possible to facetime to do two-way chat, it is not certain that you will be able to using public iOS APIs. That said, I have implemented one-way live streaming for iPhone and the difficult part was not the core streaming itself, but encoding of the payload. You will be able to do H264 in hardware and AAC / iLBC in software.
How you want to feed this to the FFMPEG depends on your transport, possibly changing from 'file' H264 frames to 'streaming' H264. Check out the H264 frame types if you implement frame dropping; reconfiguring the H264 encoder on-the-fly is not possible to my knowledge, but restarting with fresh parameters typically does not take more than a second or so.
Did you attempt to play back a live resource while capturing? That is a good starting point. If you come across an open API for H264 encoding, please post it here ;-)

Implement HTTP POST method in iphone app

I want to retrieve data from server using HTTP POST method for my iphone app.I don't have any idea about implementing it.
Please help me.
Thanks in advance
The simplest way to achieve this is to use the framework ASIHTTPRequest. Take a look in the tutorial: http://allseeing-i.com/ASIHTTPRequest/How-to-use
start with NSURLRequest and related sample code.

Internet radio in asp.net

I have database with urls of internet radio stations, but i don't know how to play stream that I am suppose to get from url. I am working in asp.net mvc2. I would be grateful if anyone can direct me to solution or give me a link to some kind of tutorial.
you can simply add windows media player control for desktop app, or HTML tag that contains that control, then using URl property set ur URL to the control and play .... try it with sth simple and URL with MMS protocol at the beginning instead
This is a client side problem. The easiest way is to use Flash to play the stream.

How to retrieve data from a website into an iphone app

I am making an iphone application.
I am a newb.
I want to fetch the data from my website. What should i do to implement this?
What needs to be done?
Help me please
Thanks
Any tutorials would be of great help.
If your problem is getting data from website to iphone then you can just use JSON Parsing to get data.
Just you have to pass all the data as JSON string in iPhone from your website. And then parse the data once received into your iPhone.
Here you can refer to this link

Hope this helps you
You will be using the NSURLConnection, NSURLRequest and NSURL classes here is an example from Apple; http://developer.apple.com/library/mac/ipad/#documentation/Cocoa/Conceptual/URLLoadingSystem/Tasks/UsingNSURLConnection.html
Expose your data from your site as WebService, XML, JSON etc. Consume that using iPhone app.
Which language is being used your site?depending on that some sample could be provided.
Chapter 10 of James Kennard, Mastering Joomla! 1.5 : APIs and Webservices contains 8 pages about XML-RPC.
For real-live examples, search the Joomla! Extension Directory.
http://extensions.joomla.org/extensions/search/xml-rpc
Here is another one to kick-start http://www.slideshare.net/coolparth/rest-api-for-joomla
For the server side, I suggest using a web service to send the data to your client.
ORIGINAL AUTHOR'S REVISION:
The September issue of Linux Journal has an excellent article on writing mobile apps that work for Android AND iPhone/iPad using free tools and frameworks. Here is a link to the article online:
Developing Portable Mobile Web Applications
Previous answers suggest using NSURLConnection, but I find it to be a bit cumbersome to use on its own. I suggest using something that wraps NSURLConnection (or CFNetwork). Some examples: ASIHTTPRequest (CFNetwork-based), httpriot and Seriously (NSURLConnection/block-based).

how to get data from web server to iphone or ipod

I'm quite new in iPhone development and I need to develop an app.
I must get mp3 data from a web server, which provides a simple saving the mp3 in my app document or folder
and use it in an application, which should also dislpay a table with rows like:
song1
song2
song3
But at present I don't know at all how to get this web page, parse it and store into an array in the application.
Please do you have any suggestion / hint / sample code ?
Thank you in advance,
There is a tutorial on the apple developer site on how to make a http request and receive data here. Should get you going on how to fetch the web page.
For parsing you can use the NSScanner or a XML/HTML parser library like TouchXML depending on your needs.
I used web services to communicate with web server, the following tutorial helped me a lot.
http://icodeblog.com/2008/11/03/iphone-programming-tutorial-intro-to-soap-web-services/
I was able to send and retrieve binary content using web service but I had to encode it first to be able to send it through Soap request and decode back Soap Response.
Hope that can help you,
