I have an existing iPhone/iPad universal app that streamed video with the MPMoviePlayerController over wi-fi (mp4) and 3G Network (3gp). When iOS 4.3 was released our 4.3 devices can no longer play a 3gp video over 3G network. I tested a local 3gp file and that fails too, but works on a 3G phone running 4.2.x.
After debugging the view controller I see the MPMoviePlayerLoadStateDidChangeNotification notification is not being triggered when trying to play the 3gp file locally or streaming it via URL.
[APPDEL showStatusView: #"Please wait..."];
NSString * videoUrl = [[request.URL description] stringByReplacingOccurrencesOfString: #"idvideo:" withString: #"http:"];
DLog(#"Loading video %#", videoUrl);
_moviePlayer = [[IDMoviePlayerController alloc] initWithContentURL: [NSURL URLWithString: videoUrl]];
_moviePlayer.view.backgroundColor = [UIColor clearColor];
_moviePlayer.allowsAirPlay = YES;
_moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
if ([_moviePlayer respondsToSelector:#selector(loadState)]) {
// May help to reduce latency
[_moviePlayer prepareToPlay];
// Register that the load state changed (movie is ready)
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayerLoadStateChanged:)
name:MPMoviePlayerLoadStateDidChangeNotification
object:_moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayerPreloadDidFinish:)
name:MPMoviePlayerContentPreloadDidFinishNotification
object:_moviePlayer];
//[NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:#selector(moviePlayerTimerUp:) userInfo:nil repeats:NO];
}
else {
// Register to receive a notification when the movie is in memory and ready to play.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePreloadDidFinish:)
name:MPMoviePlayerLoadStateDidChangeNotification
object:nil];
}
[[NSNotificationCenter defaultCenter] addObserver: self selector: #selector(onMovieDone:) name: MPMoviePlayerPlaybackDidFinishNotification object: nil];
if ([_moviePlayer respondsToSelector: #selector(view)]) {
[self.view addSubview: _moviePlayer.view];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
_moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
}
else {
_moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
}
_moviePlayer.view.frame = _webView.frame;
}
[_moviePlayer play];
The first condition for the loadState is always hit. For the 3gp file the code will never reach the moviePlayerLoadStateChanged selector method which hides an indicator/status view and creates other fullscreen/orientation notifications. The indicator/status view will just remain up & spinning. Within debugger I can see the onMovieDone selector method gets triggered far sooner than the video would of really of finished.
Confused.
This my answer in regards with playing .3gp file with iPhone .....I have successfully played .3gp file with iphone sdk with using MpMoviePlayerController and my answer link is:

I was able to play .mov file using following coding in ios 6.1.3 and below but in iOS7 it closed automatically.
MPMoviePlayerViewController *mp1 = [[ MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:url]];
if (mp1)
{
self.moviePlayer= mp1;
[mp1 release];
self.moviePlayer.view.userInteractionEnabled=YES;
self.moviePlayer.moviePlayer.repeatMode = MPMovieRepeatModeOne;
self.moviePlayer.view.frame = CGRectMake(0, 0, 320, 460);
[self.moviePlayer.moviePlayer setScalingMode:MPMovieScalingModeAspectFit];
self.moviePlayer.moviePlayer.controlStyle = MPMovieControlStyleDefault;
//Register for the playback finished notification.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(myMovieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayer.moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(myMovieFinishedCallback:) name:MPMoviePlayerDidExitFullscreenNotification object:self.moviePlayer.moviePlayer];
//setup device rotation notification observer
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(didRotate:)
name:UIDeviceOrientationDidChangeNotification
object:nil];
[self.masterVC presentMoviePlayerViewControllerAnimated:moviePlayer];
[self.moviePlayer.moviePlayer prepareToPlay];
[self.moviePlayer.moviePlayer play];
[self.moviePlayer.moviePlayer setFullscreen:TRUE];
}
Using above coding I can able to play .mp4 file in iOS7 and all. Does apple restricted mov files?
I may be having the same issue as you. If you look at your logs, do you get the following error:
_itemFailedToPlayToEnd: {
kind = 1;
new = 2;
old = 0;
}
The only other idea I have is to use a new class such as AVPlayer or even a third party class to play my media. I don't see any settings that are incorrect in your code nor my code. It is iOS 7 related though.
I am trying to play streaming file from particular URL using MPMoviePlayerController. It is working fine when I load the player but I need to keep it running when application enter into the background mode (Multitasking). This is what I am doing:
-(void) playAudio :(NSString *)playAudioURL
{
//NSURLRequest *audioFile = [[NSURLRequest alloc] initWithURL: [NSURL URLWithString:self.playAudioURL] cachePolicy: NSURLRequestUseProtocolCachePolicy timeoutInterval: 10];
MPMoviePlayerController *mediaPlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:playAudioURL]];
mediaPlayer.scalingMode = MPMovieScalingModeAspectFill;
mediaPlayer.scalingMode = MPMovieScalingModeAspectFill;
mediaPlayer.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"Home-bg.png"]];
//[self.view addSubview:mediaPlayer.view];
mediaPlayer.fullscreen = YES;
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(myMovieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:mediaPlayer];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoPreloadCallback:)
name:MPMoviePlayerContentPreloadDidFinishNotification
object:mediaPlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerPlaybackStateDidChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil];
[mediaPlayer play];
}
Now when I press iPhone home button while running the audio, it pauses the streaming until I load back the Application. I need to keep it running when app enter into background.
In your plist file, did you set the UIBackgroundModes key to audio ? Without this, your application will not play any sound in background
Note that in iOS5, UIBackgroundModes is now referenced as Required background modes when you edit your plist file.

I have encountered a problem with the MPMoviePlayerController in 3.1.2.
If I cancel the player while it is still loading, the player closes. However, the video starts playing a few moments later in the background. The only ways to stop it are to play another video or close the app. This seems to work fine in 3.2+.
Here's what I'm doing:
- (void)loadMoviePlayer
{
// Register to receive a notification when the movie has finished playing.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
if ([NSClassFromString(#"MPMoviePlayerController") instancesRespondToSelector:#selector(view)])
{
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200
// running iOS 3.2 or better
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:#"http://www.mysite.com/myvideo.m3u8"]];
[moviePlayer.view setBackgroundColor:[UIColor blackColor]];
[moviePlayer.moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
// [moviePlayer.moviePlayer setControlStyle:MPMovieControlStyleNone];
[self presentMoviePlayerViewControllerAnimated:moviePlayer];
[moviePlayer.moviePlayer prepareToPlay];
[moviePlayer.moviePlayer play];
#endif
}
else
{
MPMoviePlayerController *mMPPlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:#"http://www.mysite.com/myvideo.m3u8"]];
mMPPlayer.scalingMode=MPMovieScalingModeFill;
mMPPlayer.backgroundColor=[UIColor blackColor];
[mMPPlayer play];
}
}
- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque];
[[UIApplication sharedApplication] setStatusBarHidden:NO];
// Remove observer
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
[self dismissModalViewControllerAnimated:YES];
}
I added moviePlayBackDidFinish this morning. It gets called when I hit cancel, but dismissModalViewControllerAnimated doesn't seem to do anything. I also tried removeFromSuperView, but my player will not respond.
So, how can I make sure the player does not play after hitting "cancel"?
Thanks in advance.
You may have come across an old bug in MPMoviePlayerController. Back in the days, we actually had to play an almost empty (black, silence) M4V after playing proper content to be sure the player does not attempt to continue playback in the background when stopping at certain stages. That bug manifests in audible sound but no picture of the aborted/stopped video.
There are however a few more things worth trying when stopping (assuming your instance of MPMoviePlayerController is called moviePlayer);
set the current playback position to the complete movie duration moviePlayer.currentPlaybackTime = moviePlayer.duration;
send another stop within your notification handler [moviePlayer stop];
In my case, I found that setting the following line would eventually stop the movie player from playing:
moviePlayer.contentURL = nil;
(with moviePlayer your instance of MPMoviePlayerController).
i used all the examples and source code out there for displaying application content to external VGA display. while playing video in inside of the application am getting bellow thing in external device. any suggestion.... am i missing somthing.. but in device it showing actual window in fine way..
Hello All here am answering to my own question.
robterrell's TVOutManager will not play any video to external device by simply doing [[TvOutManager sharedinstance] startTvOut] and [[TvOutManager sharedinstance]s topTVOut];
here we have add the instance of player to tvoutWindow.
[tvoutWindow addSubview:player's instance];
but here thing is the video is not displayed in device,
but you can control external window player from device.
cheers.
NSString *url = [[NSBundle mainBundle] pathForResource:#"Overview" ofType:#"mov"];
player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:url]];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(movieFinishedCallback:)name:MPMoviePlayerPlaybackDidFinishNotification object:player];
//---play partial screen---
player.view.frame = CGRectMake(35, 450, 430, 300);
[self.view addSubview:player.view];
[player play];
- (void) movieFinishedCallback:(NSNotification*) aNotification {
[[TVOutManager sharedInstance] startTVOut];
player = [aNotification object];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player stop];
}
this the code am added in mainviewController class in robterrell's TVOutManager sample application. after connecting device into external device. while switching mirror video on am not getting anything..
The code below is more or less taken from the example MPMoviePlayerController sample code. In an app I wrote last year, it used to play videos fullscreen without an issue. Since iOS 4.0, there's just audio in the background. It's like the movie player doesn't have a view or the view is behind my app. I can still interact with my app, even 'start' a new video (audio only).
It's like the movie player now needs a view, but I don't see any way of supplying this in the API or the sample code (which does seem to be a version or two behind.
I load my videos from a URL and if I type these into Safari, they play just fine.
Here's the relevant code fragments, for what it's worth:
- (void)playMovieUrl:(NSURL*)url
delegate:(id)delegate
callbackSelector:(SEL)selector
{
#try {
movieFinishedCallbackDelegate = delegate;
movieFinishedCallbackSelector = selector;
movieURL = url;
MPMoviePlayerController* theMovie=[[MPMoviePlayerController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(myMovieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:theMovie];
[theMovie play];
}
#catch (NSException * e) {
return;
}
}
// When the movie is done,release the controller.
-(void)myMovieFinishedCallback:(NSNotification*)aNotification
{
MPMoviePlayerController* theMovie=[aNotification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:theMovie];
[theMovie release];
[movieURL release];
[movieFinishedCallbackDelegate performSelector:movieFinishedCallbackSelector];
}
You probably need to present theMovie:
[self presentMoviePlayerViewControllerAnimated:theMovie];
And change to:
MPMoviePlayerViewController
in ios 3.2 letter use MPMoviePlayerViewController. it behave like a modelViewcontroller
