In my iPhone App I need to show the videos which are in Flash format.
I asked the client to change the videos in iPhone compatible format. They stored the converted the video on a server and I am able to show the video using MPMoviePlayerController.
Now we need to store around 25 videos (Each around 300 MB) and access them via iPhone App using MPMoviePlayerController
I have to help the client figure out how or where to host these files.
So some questions are there
1) What all things need to be taken care on server side for better performance? Is there any document available for this?
2) The video will be streaming or progressive download ? Do we have a choice?
I am sure many people would have done it. So kindly help in this regard.
if video is more then 10 minutes then you have to use streaming not progressive and you have to prepared playlist on server side with .m3u8 format. you just need to pass this url with .m3u8 into the mpmediaplayercontroller and this will take care of every thing from client side.
For server side functionality you can search apple code for streaming video.

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:
Setting Up Live Application
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.
I am trying to create a streaming video DVR like functionality in an app I am developing. I have an HTTP Live Stream that I have successfully gotten to play on the iPad. I want the user to be able to push the "Record" button, and begin recording the video that is currently playing from that point. This video file will be accessible from the app or from the camera roll. Currently, I am using the MPMoviePlayerController object to play the video stream. I do not see any methods of accessing the data from the object in Apple's documentation. Here are some thoughts I had on ways of going about this.
1) Somehow access the video data from MPMoviePlayerController, and write this to a file. Or use another type of player object that will allow me to play the video and access the currently playing data.
2) Implement some sort of screen capture recording that gets a video capture of the iPad's screen. This would allow me to record the video in a "screenshot" sort of way.
3) Locate the HTTP Live Streaming video segments where they are stored by MPMoviePlayerController. Presumably they need to be stored somewhere on the iPad for playback. Is there a way of accessing these files?
4) Manually download the stream video segments over http while streaming the file. This seems like its not ideal since the stream would have to be downloaded twice.
5) This could work. Periodically download the video segments to the iPhone. Set up a local http server on the iPhone and server the videos to the MPMoviePlayerController. This way the video segments could be marked for recording and assembled into a video.
6) I do have control of the streaming server. I could write some server side code to record the video on the server end, then send the video to the iPad after the fact. I would rather not do this.
Has anyone done any of these things? Ideally the iPhone would just be able to access the video data somehow and easily record it. I would rather not get into options 4, 5, or 6 (above) if I don't have to.
Thanks in advance.
DVR on the device is somewhat not encouraged, due to the limited space available and other factors like battery life, processing power, cleanup procedures after the user stops the dvr, etc.
If you want to achieve DVR playback on iOS devices (or other devices using HLS), I suggest you keep the video server side. The live stream is already captured and segmented server side, all you would have to do is keep the segments a bit longer, instead of deleting them. By using the EXT-X-PLAYLIST-TYPE and EXT-X-MEDIA-SEQUENCE tags, you can suggest to the player that he's opening a live stream which has DVR (earlier) video available.
Alternatively, you can use a server that does that out of the box, for example Wowza. Here's an article on how to achieve this with Wowza
What technology is used for live streaming of video from iPhone cam to a distant server.
I want to show live streaming as well as save the video, once it gets finished.
The way its being done right now is by capturing the frames as the movie is taken (right now its being done through a screenshot private api, but now with 4.0 u can grab the frame of videos a better way, cant discuss that right now tho), then take some number of frames, encode them using ffmpeg or some ohter encoding library, send the video chunks to your server and live stream them using the live http streaming...thats a birdeye view of how its being done..hope it helps
How can I stream video data from the network and play it on an iPhone?
First, are you developing a Web app optimized for iPhone or a native application ?
In the first case, your only option is to transcode your video files to Quicktime H.264 (m4v or mp4 extension). You can use Quicktime Pro (use the export menu) or VLC (as a free alternative). Then simply add a hyperlink to the video file on your HTTP server. Make sure it presents the right content-type and stuff (read Safari Web Content Guide for iPhone OS: Configuring Your Server). That'll work for web and native apps (in a native app you would use the MPMoviePlayerController view). So can "stream" (technically called progressive download of a Quicktime movie file).
If you're talking about streaming live content (i.e. content that you produce live or transcode a live feed) there is currently no official way of doing it (as of iPhone OS 2.2). iPhone OS does not support RTSP/RTP streaming. A number of native iPhone applications (such as UStream.tv and Orb Live) have created their custom live streaming solution (most of them transfer a delayed streams with many seconds of latency over HTTP then somehow decode it on the phone using FFmpeg or other libraries).
Are you trying to stream video in your app or just streaming on your iPhone? For streaming video through an app, use the MPMoviePlayerController and pass the URL of your video to it. The MPMoviePlayerController will itself stream the video and play it for you.
If you're looking for a server based solution (with a very affordable Amazon EC2 option), be sure to check out Wowza at http://www.wowzamedia.com/advanced.php
It streams directly to iPhone/iPod Touch without a custom app.
note: I'm not affiliated with them at all... just a fan/customer.
edit: Just noticed how old this question was. :)
I am planning to write an iPhone app which can display streaming audio/video from the internet (backend would most probably be Red5 or Wowza and video will be streamed on RTMP (although I have the option to change that). Any ideas on implementation?

You better know that, and start looking at HTTP Live Streaming!
Displaying the video is as simple as having the <video> tag in an HTML5 page, but there should be an API also for that (I am not an iPhone developer)
