Could anyone shed light upon how to capture a live video which is on a desktop and integrate the same to my iphone, so that i can view same live video on my iphone. I am stuck as to where to start. If anyone could give technical info would be greatly helpful.
thanks in advance
The new QuickTime X in Snow Leopard has support for a new feature called HTTP Live Streaming, which works with clients including the iPhone. There are several examples in the ADC of how to capture from the screen. You would then need to run it through a compressor (most likely H.264) and use a web server (such as the built-in Apache) to distribute the content over the network.

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.

Edit:
Here is the article explaining opentok using parse.

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 ;-)
I just started work on live streaming on iPhone. So any help of how to do live streming in iPhone. I think if I can add video tag in HTML5 and then load that html in UIWebView will work.
Am I right? If not what is your sugestion to do live streaming. I want to embed some news channel live streaming link in the application so from where I can find those links.
You have to go through HTTP Live streaming document provided by Apple.There are some sample live streaming URLs.The file extension will be .m3u8.If you want to configure your own webwserver , you have to configure FFMPEG server in your webserver.The links which will help you

If you're making a web app in html5 then the video tag is a good choice.
But, If you're developing a native app then MPMoviePlayerController would be a much better choice. There are many example of how to use it online.
iOS doesn't support RTMP or RSTP, so your stream would need to be a HTTP Live stream. From memory the codec choice is very limited too, eg if you supply H264+mp3 you won't get any sound despite iOS supporting mp3.
Also remember that streams from other people (such as the BBC) will normally be protected by international copyright law, so unless you have prior permission to use their stream in your app you may be breaking the law.
Apple has some nice resources on Http Live Streaming.
Since iphone doesn't support flash at all.
Is it Darwin streaming server ?
You'll want to use what Apple refers to as HTTP Live Streaming. Follow that link to Apple's Overview documentation. That should give you enough to start with, as well as links to more detailed documentation.
In particular, take note of the Requirements for Apps section. Here Apple lays out the required use of HTTP Live Streaming for iOS apps that will be delivering video over the cellular network.
You can stream video (H.264) on iphone with Wowza Media Server 2
I have run into a bit of a problem. I built an iPhone app that streams my podcasts via the MPMoviePlayerController. Apple will not approve it because it can use too much bandwidth over the Carrier Network. So their workaround is to use a Stream Segmenter. I am unable to install a stream segmenter on my server. Are their ANY other solutions people have come up with that can help me stream my podcast to iPhone devices? Even if I have to make it a Web Application as opposed to a native application.
Thanks,
John
You could use a simple service like Encoding.com to create iphone segmented ondemand versions of your files for multi bitrate adaptive playback. You could also provide a high and low quality and only display the high when the reachability class shows that your using wifi. I had to do the second option to get one of my apps to pass approval. Hope this helps!
Well if you don't want a native app, I think you can just put a video link on a webpage and when the user clicks it Quicktime will take over and play the file. It will play the file as it downloads it.
I don't have any experience streaming large files over the iPhone, so I can't help guide you on alternatives and keeping it a native app.
I want to show live video streaming which is in the form of flash. Can any body tell me how to do this in an iPhone application.
Thanks

The iPhone doesn't support Flash, so using it isn't an option. You can, however, do HTTP streaming of video. Read Apple's documentation for more information.
Adobe announced during their Keynote at MAX yesterday that you will be able to compile Flash for iPhone apps. They have some sample projects available on the Adobe labs site
You can take those sample files and extend them to accomplish what you're looking for.
The native compile output from Flash Professional isn't going to be available until CS5.
Note: Flash is not native on the iPhone and will not run in browser. Also, apps will not have access to the video camera or the microphone.
No flash but you can stream mp4 etc.
good tutorial on how to stream video:
