Playing video in iPad application from server - iphone

Question

I want to play a video which is uploaded to the server from an iPad application, but when the screen loads it gives an error:
An AVPlayerItem cannot be associated with more than one instance of AVPlayer
I am using the following code:
-(void)playVideo{
NSURL *url = [NSURL URLWithString:#"http://celeritas.com.pk/emrapp/test.mp4"];
MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:mp];
mp.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
[self presentMoviePlayerViewControllerAnimated:mp];
[mp release];
NSLog(#"Successfully playing thanks");
}
-(void)playbackFinishedCallback:(NSNotification *)notification{
MPMoviePlayerController *movie = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:movie];
[movie release];
}

Answer 1

http://celeritas.com.pk/emrapp/test.mp4 the URL seems to be wrong...
The requested URL /emrapp/test.mp4 was not found on this server.
Any way this will work
.h
MPMoviePlayerViewController * plyr;
NSURL * url;
#property (nonatomic,retain) MPMoviePlayerViewController *plyr;
#property (nonatomic,retain) NSURL *url;
.m
#synthesize plyr ;
#synthesize url;
url = [NSURL URLWithString:#"valid url"];
plyr = [[MPMoviePlayerViewController alloc] initWithContentURL:url];

Answer 2

Url might be wrong double check that video url link is accessible, secondly do see your network firewall this might also cause problem.
The one tweak you can change instead of:
mp.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
use:
mp.moviePlayer.movieSourceType = MPMovieSourceTypeUnknown;

Answer 3

try this
create object of MPMoviePlayerViewController in .h like MPMoviePlayerViewController *mp;
#import<MediaPlayer/MediaPlayer.h>
mp = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:url]];
[[mp moviePlayer] prepareToPlay];
[[mp moviePlayer] setUseApplicationAudioSession:NO];
[[mp moviePlayer] setShouldAutoplay:YES];
[[mp moviePlayer] setControlStyle:2];
[[mp moviePlayer] setRepeatMode:MPMovieRepeatModeOne];
[self presentMoviePlayerViewControllerAnimated:mp];

Answer 4

try this Code
-(IBAction)playMovie:(id)sender
{
NSURL *fileURL = [NSURL URLWithString:#"http://www.youtube.com/watch?v=3Qjh56woQMw"];
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;
[moviePlayerController play];
}
- (void)moviePlaybackComplete:(NSNotification *)notification
{
MPMoviePlayerController *moviePlayerController = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotificationobject:moviePlayerController];
[moviePlayerController.view removeFromSuperview];
[moviePlayerController release];
}
