I'm working on an iPhone app that will use HTTP Live Streaming. Using Apple's provided tools (particularly mediafilesegmenter), I'm able to successfully segment and serve an archived video. Now I want to test Live Streaming stuff. I don't own any sort of camcorder, I just have my iSight built-in to my Mac. Is there a way to leverage this camera to test out Live Streaming? Run iSight from the command line maybe? If so, I need a port number for mediastreamsegmenter.
I haven't tried this out on an iPhone but I would imagine it would work:

Note that the post says you need a nightly build of VLC, this is now out of date - as long as you're using 1.0 you should be fine.

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 have a http streaming link which gives me .flv streaming feed. I want to convert that and access in my iPhone program. How can i do that? I want to have a desktop software like VLC and input this streaming feed URL and convert to iPhone supported and stream again to iPhone. I tried VLC with H.264 and Mpeg-1 audio, but seems to be it doesn't give the supported format, so as iPhone program doesn't play the video.
Could someone please guide me how can i setup a desktop software which can stream iPhone supported file?
Thanks in advance.
I think even the great VLC can't convert FLV on the fly...(or even do anything with FLV). As far as streaming goes, you'll probably be limited to the local network (Wi-Fi). I'd start with the simple way—create an ad-hoc file server on the desktop, then use AVPlayer's initWithURL method to find that video.
On the desktop, you could query the IP address of the computer, and ask the user to enter that URL (along with an optional port assignment and file component, like http://192.168.0.2:2234/streamingVideo.mp4) onto the iDevice, then convert to NSURL.
What exactly is the http streaming link? This matters a lot as in order to stream to the iPhone you need to use HTTP Live Streaming which requires some different bits than a typical flash media, or more properly RTMP, server. Typically you need two different streaming architectures or some expensive boxes.
Is there any available open-source (preferred) or commercial library for on-fly segmenting and streaming of video to iPhone / iPad?
Also, is there any open-source/commercial server (alternative to Wowza) which supports this?
Apple offers mediastreamsegmenter:
https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/StreamingMediaGuide/UsingHTTPLiveStreaming/UsingHTTPLiveStreaming.html
You might also want to peek at Best Practices for Creating and Deploying HTTP Live Streaming Media for the iPhone and iPad:
https://developer.apple.com/library/content/technotes/tn2224/_index.html
There's also Darwin Streaming Server, but you may not need it.
Your first preoccupation should be to try to peek a good segmenter (video speaking): Apple's one is fine.
Then, if you wan't in-memory segmenting, mount the input source folder to a RAMdisk...
Take a look at following link;
http://developer.apple.com/library/ios/#samplecode/MoviePlayer_iPhone/Introduction/Intro.html
This example will show how to play videos from a network based URL.
For more details about playing videos;
You can check red5(java & opensource).
Check lastest beta, or code in svn (as lot hav changed since last officeial release).
It may or may not be able to do that out-of-the-box, if not you can code your red5 app and/or check others people code built arround red5...
I want to be able to (live) stream the frames/video FROM the iPhone camera to the internet. I've seen in a Thread (streaming video FROM an iPhone) that it's possible using AVCaptureSession's beginConfiguration and commitConfiguration. But I don't know how to start designing this task. There are already a lot of tutorials about how to stream video TO the iPhone, and it is not actually what I am searching for.
Could you guys give me any ideas which could help me further?
That's a tricky one. You should be able to do it, but it won't be easy.
One way that wouldn't be live (not answering your need, but worth mentioning) is to capture from the camera and save it to a video file. see the AV Foundation Guide on how to do that. Once saved you can then use the HTTP Live Streaming segmenter to generate the proper segments. Apple has applications for Mac OSX, but there's an open source version as well that you could adapt for iOS. On top of that, you'd also have to run an http server to serve those segments. Lots of http servers out there you could adapt.
But to do it live, first as you have already found, you need to collect frames from the camera. Once you have those you want to convert them to h.264. For that you want ffmpeg. Basically you shove the images to ffmpeg's AVPicture, making a stream. Then you'd need to manage that stream so that the live streaming segmenter recognized it as a live streaming h.264 device. I'm not sure how to do that, and it sounds like some serious work. Once you've done that, then you need to have an http server, serving that stream.
What might actually be easier would be to use an RTP/RTSP based stream instead. That approach is covered by open source versions of RTP and ffmpeg supports that fully. It's not http live streaming, but it will work well enough.
I need to create streaming application on iPhone. I have gone through apple's developer forum already. What I want to do here is that I would be implementing my own streaming method. To start with I need to create an application which can get file from some URL using simple streaming and then will display in window (view). I cannot use browser here.
Can someone please help?
Isn't this (HTTP Streaming) or this (Apple live video streaming) what you intend?
Http live stream (for videos) has been released with the 0S 3.0.
It's not clear if you are talking about video streaming or else.
If it's audio streaming, check out this cocoa with love article.
A lot of people use this as their starting point.
