Hello all i use windows encoder to stream video online and have a server that i use to broadcast this stream. i am trying to make an app that streams video to the iPhone/iPad using a unique link. i have seen apps out that stream their own DVR cameras so there must be a type of converter or encoder to use. any suggestions?
The short answer is no, not at this time. The iPhone/iPad/iPod Touch work natively with the Apple HTTP Adaptive segmented streaming protocols. MMS (Windows Media) streams are not compatible with "i" devices and will not play. You will need to look into encoding your video with this other format. Check out the Apple specs for a full description of the protocol. Future versions of Windows Media Services (4.0) are claiming that they will support the Apple protocols but this is only a preview/beta at this time and may not truly support the Apple specs.
If your trying to do on-demand iPhone video, you can utilize a service such as Encoding.com to pre-encode your files in the adaptive segmented format for your users to view. For live encoding, Telestream has a product called Wirecast which can encode in a h.264 Apple approved baseline format which can be sent to a service such as Akamai, Multicast Media, or Wowza Server for distribution to your clients.

I am working on an iOS application to stream live video from iPhone to a media server and then make it available to a larger audience using RTSP.
Which protocol or method I should use to send the video stream to a server.
Thanks.
HTTP Live streaming is not designed for you needs, it's for server->clients + I won't comment about huge delay it implies
You better check RTSP or RTMP protocol and LivU blog

Apple seems to make a distinction between apps that are used for just streaming content from servers and those that are used for some type of conferencing.
I think VOIP types are safe, and it seems like gocoder presenter types apps don't have issues either. There's no official page detailing this, but there is some mention under what apples considers VOIP app.
No app has issues if its over wifi only.
I'm looking for a way to create an app that will allow captured camera video to be streamed on a computer. For example, one person could be walking an iPhone around a room and another person could have that video streamed on their computer. Something kind of like a one-way Facetime except the receiver is on a computer. Also, I can't just use an existing app as later I would like to change the program to do some computer vision processing on the incoming data.
At the moment, I've found that AV Foundation should be the correct option for the video capture (from this question). However, I'm having difficulty finding the method by which I can actually stream this data. In particular, searching for how to create the apps on the iPhone frequently results in existing apps that do the task, but not how to create the app.
Can anyone give me a pointer to the information on how to stream the video capture from the iPhone? Thank you much.
You can use "Wowza media Server" for Streaming purpose
For wowza media server doenload :
Wowza Download
After installing wowza Now you need to set up live setting in wowza for that purpose you need:

For iOS side there is library is useful for video streaming using RTMP connection
You can get Library at
RTMP library for Streaming
Library example
RTMP library for Streaming example
In this good example of Streaming from iOS side
I had success with ANGL lib and Wowza media server. It gives smooths RTMP stream.
If streaming video to an iOS device, do I have to use HTTP Live Streaming? Is HDS supported? The problem is we have limited storage space and HTTP Live Streaming would require us to have more video files. Can someone give me some elucidation on these matters?
If your app will stream more than 10 minutes of video Apple requires that you use HTTP Live Streaming to deliver the video, otherwise your app will be rejected when you submit it to the app store. (This happened to me the first time I submitted my app, before I knew about this requirement.)
From the HTTP Live Streaming Overview:
Warning iOS apps submitted for distribution in the App Store must
conform to these requirements.
If your app delivers video over cellular networks, and the video
exceeds either 10 minutes duration or 5 MB of data in a five minute
period, you are required to use HTTP Live Streaming. (Progressive
download may be used for smaller clips.)
If your app uses HTTP Live Streaming over cellular networks, you are
required to provide at least one stream at 64 Kbps or lower bandwidth
(the low-bandwidth stream may be audio-only or audio with a still
image).
These requirements apply to iOS apps submitted for distribution in the
App Store for use on Apple products. Non-compliant apps may be
rejected or removed, at the discretion of Apple.
iOS devices support HTTP progressive download for .mp4 files, the server could be simply Apache or Nginx. The user experience is quite similar to HTTP live streaming.
RTSP is also possible. You can migrate live555 to iOS platform as the RTSP client, as use DarwinStreamingServer as the RTSP server.
I think that HTTP progressive download is the alternative solution. We already done it through a simple HTTP server. For RTSP or other type of protocol you have to implement it by yourself.

Which web player I can use to get live stream from Windows Media Services? Is there are any crossplatform solutions (Windows, iPad/iPhone)? Should I make live convertation to flv or any other trick?
You could try using h264/aac video format for targeting iOS systems as explained in this article: Apple HTTP Live Streaming with IIS Media Services (this is kind of your only choice if you want to support iphone/ipad etc). This format will also be valid for Windows Phone 7 devices.
For the rest of Windows-based systems you could use Silverlight as streaming client, although you will need to use a different format based on Windows Media Video.
Can we stream live audio which is in WAV format from iPhone to server?
Yes. Yes, we can.
I use DNLA applications very often to stream media to/from my devices (iPhone, iPod, Android, Laptop) and a server in my home. The WAV format is most certainly supported among many others.
You can read up on DNLA here. It's an organization that outlines a set of interoperability guidelines that allow servers and clients to stream various formats of media. I love it.
There is no shortage of DNLA compatible apps for both the iPhone and Android. On my wife's iPhone, I use the free version of iMediaShare.
And on my Android, I use AndroMote.
Now, if you want to know how to do this as a developer, I have no idea since I don't write for the iPhone. However, the answer to your actual question is "Yes," it can be done and there are plenty of apps that do it via the DLNA or Universal Plug N Play (UPnP) guidelines.
