How to send the video captured from iPhone's camera to a server for live streaming?

I have got some code online which captures video from the camera of iPhone and then stores it to a video file and it is working fine. But my purpose is not to save it in the memory, but to send it to a sever. I have found out that there is a free media server named WOWZA which allows streaming and also Apple has (HSL) HTTP Live Streaming feature and that the servers expect the video to be in h.264 format for video and in mp3 for audio. By reading some of the documents about Apple HSL I also came to know that it gives a different url in the playlist file for each segment of the media file which is then played in the correct order on a device through the browser. I am not sure how to get small segments of the file that is recorded by the phone's camera and also how to convert it into the required format. Following is the code for capturing video:

Implementation File

#import "THCaptureViewController.h"
#import <AVFoundation/AVFoundation.h>
#import "THPlayerViewController.h"

#define VIDEO_FILE @"test.mov"

@interface THCaptureViewController ()
@property (nonatomic, strong) AVCaptureSession *captureSession;
@property (nonatomic, strong) AVCaptureMovieFileOutput *captureOutput;
@property (nonatomic, weak) AVCaptureDeviceInput *activeVideoInput;
@property (nonatomic, strong) AVCaptureVideoPreviewLayer *previewLayer;
@end

@implementation THCaptureViewController

- (void)viewDidLoad 
{
[super viewDidLoad];

    #if TARGET_IPHONE_SIMULATOR
    self.simulatorView.hidden = NO;
        [self.view bringSubviewToFront:self.simulatorView];
    #else
    self.simulatorView.hidden = YES;
    [self.view sendSubviewToBack:self.simulatorView];
    #endif

// Hide the toggle button if device has less than 2 cameras. Does 3GS support iOS 6?
self.toggleCameraButton.hidden = [[AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo] count] < 2;
