how to implement MPMoviePlayerViewController in iPhone?

Hi every one,
Please take a look at MPMoviePlayerController integration for local/live video playing in iPhone/iPad/iPod Touch (iOS 4.0 and later..).

Step 1 : Add "MediaPlayer.framework" into your project resource.
Step 2 :  Import <MediaPlayer/MediaPlayer.h> into your class where you want to use MediaPlayer for playing videos (local/live).
Step 3 : Place below code into the controller class where you want to integrate player.

-(IBAction)btnVideoClicked:(id)sender
{
    @try
    {
        NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init];
        GetVideos *obj_video = [arrVideos objectAtIndex:[sender tag]];
        MPMoviePlayerViewController *moviePlayerViewController = [[MPMoviePlayerViewController alloc]initWithContentURL:[NSURL URLWithString:obj_video.VideoPath]];
        [moviePlayerViewController.moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
        [moviePlayerViewController.moviePlayer setShouldAutoplay:YES];
        [moviePlayerViewController.moviePlayer setFullscreen:NO animated:YES];
        [moviePlayerViewController setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
        [moviePlayerViewController.moviePlayer setScalingMode:MPMovieScalingModeNone];
        [moviePlayerViewController.moviePlayer setUseApplicationAudioSession:NO];
        // Register to receive a notification when the movie has finished playing. 
        [[NSNotificationCenter defaultCenter] addObserver:self 
                                                 selector:@selector(moviePlaybackStateDidChange:) 
                                                     name:MPMoviePlayerPlaybackStateDidChangeNotification 
                                                   object:moviePlayerViewController];
        // Register to receive a notification when the movie has finished playing. 
        [[NSNotificationCenter defaultCenter] addObserver:self 
                                                 selector:@selector(moviePlayBackDidFinish:) 
                                                     name:MPMoviePlayerPlaybackDidFinishNotification 
                                                   object:moviePlayerViewController];
        [self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];
        moviePlayerViewController.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
        [moviePlayerViewController release];
        [pool release];
    }
    @catch (NSException *exception) {
        // throws exception
    }
}


#pragma mark -----------------------
#pragma mark MPMoviePlayer Notification Methods

-(void)moviePlaybackStateDidChange:(NSNotification *)notification
{
    MPMoviePlayerViewController *moviePlayerViewController = [notification object]; 

    if (moviePlayerViewController.moviePlayer.loadState == MPMovieLoadStatePlayable &&
        moviePlayerViewController.moviePlayer.playbackState != MPMoviePlaybackStatePlaying)
    {
        [moviePlayerViewController.moviePlayer play];
    }
   
    // Register to receive a notification when the movie has finished playing. 
    [[NSNotificationCenter defaultCenter] removeObserver:self 
                                                 name:MPMoviePlayerPlaybackStateDidChangeNotification 
                                               object:moviePlayerViewController];
    moviePlayerViewController = nil;
}

- (void) moviePlayBackDidFinish:(NSNotification*)notification
{ 
    MPMoviePlayerViewController *moviePlayerViewController = [notification object]; 
    [[NSNotificationCenter defaultCenter] removeObserver:self 
                                                    name:MPMoviePlayerPlaybackDidFinishNotification 
                                                  object:moviePlayerViewController]; 
    [self dismissMoviePlayerViewControllerAnimated];
    moviePlayerViewController = nil;
}

How to integrate live audio streaming in iPhone?

Hi everyone,
I think, all of you heard about live audio/video streaming. I'm going to share "Live Audio Streaming" example with you.
Please check this :

Step 1: First of all, you have to download these two files(AudioStreamer.h, AudioStreamer.m) from http://code.google.com/p/audiostreamer-meta/source/browse/trunk/Classes

Step 2: Add necessary frameworks and above two files into your project.

Step 3: Implement below code to your project file.

@class AudioStreamer;

@interface CallerTuneListViewController : UIViewController
{
    AudioStreamer *streamer;
}

#import "CallerTuneListViewController.h"

#import "AudioStreamer.h"
#import <QuartzCore/CoreAnimation.h>
#import <MediaPlayer/MediaPlayer.h>
#import <CFNetwork/CFNetwork.h>
#import <AudioToolbox/AudioToolbox.h>

@implementation CallerTuneListViewController

#pragma mark ---------------------------------
#pragma mark View LifeCycle

-(void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    if ([streamer isPlaying]) {
        [self destroyStreamer];
    }
}

#pragma mark ---------------------------------
#pragma mark Memory Management

- (void)dealloc
{
    [self destroyStreamer];
    [super dealloc];
}

#pragma mark ---------------------------------
#pragma mark UIButton Actions

-(IBAction)playLiveStream:(id)sender
{
            if (![streamer isPlaying])
                {
                    [self createStreamer:AudioFilePath];
                    [streamer start];
                }
                else
                {
                    [streamer stop];
                }
}


#pragma mark ---------------------------------
#pragma mark AudioStreamer Methods

// Removes the streamer, the UI update timer and the change notification
- (void)destroyStreamer
{
    if (streamer)
    {
        [[NSNotificationCenter defaultCenter]
         removeObserver:self
         name:ASStatusChangedNotification
         object:streamer];
      
        [streamer stop];
        [streamer release];
        streamer = nil;
    }
}

// Creates or recreates the AudioStreamer object.
- (void)createStreamer:(NSString *)audioPath
{
    if (streamer)
    {
        return;
    }
  
    [self destroyStreamer];
  
    NSURL *url = [NSURL URLWithString:audioPath];
    streamer = [[AudioStreamer alloc] initWithURL:url];

    [[NSNotificationCenter defaultCenter]
     addObserver:self
     selector:@selector(playbackStateChanged:)
     name:ASStatusChangedNotification
     object:streamer];
}

// Invoked when the AudioStreamer
// reports that its playback status has changed.
- (void)playbackStateChanged:(NSNotification *)aNotification
{
    if ([streamer isWaiting])
    {
    }
    else if ([streamer isPlaying])
    {
    }
    else if ([streamer isIdle])
    {
        [self destroyStreamer];
    }
}

I hope this will be useful to all...

Thanks ,
