I am trying to use MPMoviePlayerController to play m4v file before the game starts. The game is cocos2d based.
I made a MPMoviePlayerController with the required file and added it as child to CCDirector (which is a subclass of UIViewController). The reason why I am adding MPMoviePlayerController as child is that I want the game to keep loading in background.
My problem is that I am unable to find a way to remove the MPMoviePlayerController after the video finishes.
Please give suggestions.
Thanks in advance.
For cocos2D game CCVideoPlayer class is best and easy to play video. CLICK HERE FOR EXTENSION
You should be able to listen for the MPMoviePlayerPlaybackDidFinishNotification notification, then remove the subview. This code worked in my tests:
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
self.player = moviePlayer;
moviePlayer.controlStyle = MPMovieControlStyleNone;
moviePlayer.shouldAutoplay = YES;
[moviePlayer prepareToPlay];
moviePlayer.view.frame = self.view.bounds;
moviePlayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self.view addSubview:moviePlayer.view];
[moviePlayer play];
// wait for the video to finish...
MyViewController __weak *weakSelf = self;
[[NSNotificationCenter defaultCenter] addObserverForName:MPMoviePlayerPlaybackDidFinishNotification object:self.player queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification *note) {
[[NSNotificationCenter defaultCenter] removeObserver:weakSelf name:MPMoviePlayerPlaybackDidFinishNotification object:weakSelf.player];
// remove the view
[weakSelf.player.view removeFromSuperview];
}];
If that doesn't work, you may need to post your player creation and setup code for us to help you figure out what's going on.

I'm really going crazy with my welcome view controller.
I have a video in background in continuos loop but every solution that I used causes a small pause/flash when the video is finished and loop.
I use two solution: MPMoviePlayerController and AVPlayer from AVFoundation but I got the same result, a small white flash when video is looped for replay.
My MPMoviePlayerController solution (I prefer a fix for this)
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *videoURL = [[NSBundle mainBundle] URLForResource:#"welcome_video" withExtension:#"mp4"];
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
self.moviePlayer.controlStyle = MPMovieControlStyleNone;
self.moviePlayer.scalingMode = MPMovieScalingModeAspectFill;
self.moviePlayer.view.frame = self.view.frame;
[self.view insertSubview:self.moviePlayer.view atIndex:0];
[self.moviePlayer prepareToPlay];
// Loop video
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(loopVideo) name:MPMoviePlayerPlaybackDidFinishNotification object:self.moviePlayer];
}
- (void)loopVideo
{
[self.moviePlayer play];
}
My AVPlayer solution
(void)viewDidLoad
{
[super viewDidLoad];
NSError *sessionError = nil;
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:&sessionError];
[[AVAudioSession sharedInstance] setActive:YES error:&sessionError];
//Set up player
NSURL *movieURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"welcome_video" ofType:#"mp4"]];
AVAsset *avAsset = [AVAsset assetWithURL:movieURL];
AVPlayerItem *avPlayerItem =[[AVPlayerItem alloc]initWithAsset:avAsset];
self.avplayer = [[AVPlayer alloc]initWithPlayerItem:avPlayerItem];
AVPlayerLayer *avPlayerLayer =[AVPlayerLayer playerLayerWithPlayer:self.avplayer];
[avPlayerLayer setVideoGravity:AVLayerVideoGravityResizeAspectFill];
[avPlayerLayer setFrame:[[UIScreen mainScreen] bounds]];
[self.movieView.layer addSublayer:avPlayerLayer];
//Config player
[self.avplayer seekToTime:kCMTimeZero];
[self.avplayer setVolume:0.0f];
[self.avplayer setActionAtItemEnd:AVPlayerActionAtItemEndNone];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[self.avplayer currentItem]];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerStartPlaying)
name:UIApplicationDidBecomeActiveNotification object:nil];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[self.avplayer pause];
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[self.avplayer play];
}
- (void)dealloc
{
[[NSNotificationCenter defaultCenter] removeObserver:self name:AVPlayerItemDidPlayToEndTimeNotification object:nil];
}
- (void)playerItemDidReachEnd:(NSNotification *)notification
{
AVPlayerItem *p = [notification object];
[p seekToTime:kCMTimeZero];
}
- (void)playerStartPlaying
{
[self.avplayer play];
}
What's wrong with these implementation? I really try different fixes found on this site but nothing seems to work.
Any suggestions?
Hm.. I might have an idea for the AVPlayer-approach.
The AVPlayer has this method:
- (void)setRate:(float)rate
time:(CMTime)itemTime
atHostTime:(CMTime)hostClockTime
This means that you can specify WHEN you want the AVPlayer to start at kCMTimeZero. I have not actually used it, but I have an idea for how it can work.
You need to know exactly the moment you start the video the first time. I see you have your own -(void)playerStartPlaying which is called by the notificationCenter on didBecomeActive. I suggest using this method for app variations of [player play];, so put
[self playerStartPlaying];
inside viewDidAppear instead of [self.avplayer play];. It might be good enough.
If you here manage to find the device's hostClockTime, and add the length of the video, you should end up with the exact time when you want it to start from scratch. I am not testing any of this, and I'm typing from head, so you need to understand what I'm doing, and fix it yourself.
- (void)playerStartPlaying
{
//The device's hostClockTime. Basically a number indicating how long the device has been powered on.
CMTime hostClockTime = CMClockGetHostTimeClock;
//A CMTime indicating when you want the video to play the next time.
CMTime nextPlay = CMTimeAdd(hostClockTime, self.avplayer.currentItem.duration);
/* I don't know if that was correct or not, but you'll find out */
//Start playing if we're not already playing. There might be an avplayer.isPlaying or something, I don't know, this is probably working as well..
if(self.avplayer.rate != 1.0)
[self.avplayer play];
//Tell the player to restart the video at the correct time.
[self.avplayer setRate:1.0 time:kCMTimeZero atHostTime:nextPlay];
}
You'll have to remove the entire AVPlayerItemDidPlayToEndTimeNotification-thing. When the video has reached the end, it's already too late. What we're doing now is telling it when to play the second turn when we start the first. We want nothing to happen when didPlayToEndTime is fired, we're handling it manually.
So, if you understand what I have done above, you'll also notice that the video only will play twice. We tell the video to play, at the same time as we tell it to replay at time = now+videoLength. When that replay is done, nothing happens. It simply reaches end. To fix this, you'll need to somehow call -(void)playerStartPlaying at the same time as the setRate:time:atHostTime is executed on the AVPlayer. I guess you could start an NSTimer or dispatch_time and let it execute he method in exactly nextPlay-amount of time, but that would kinda defeat the purpose of this thing. Maybe not. You could try different stuff out. You probably CAN do this with some success, but I suggest finding a way to register for when the player started from the start. Maybe you can observe the rate or something, I don't know.. If you want to try it with a delayed method, you can try this:
double delayInSeconds = CMTimeGetSeconds(self.avplayer.currentItem.duration); //or something
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
[self playerStartPlaying];
});
Just keep in mind that this is some recursive shit, so even if you pause the video, this will still keep calling after that duration. In that case I suggest making a BOOL paused; and cancel the execution of the entire playerStartPlaying if it's set to YES. ..and of course set paused = YES; whenever you want to pause, next to wherever you say [player pause];
If this actually works, but you still get flashes, I know there are several ways to improve this. For instance, the CMTimeAdd() should probably be using some kind of synchronization-tool to make sure the times add up using the correct timeScale etc.
I have now spent way too much time writing this, and it might not even work. I have no idea. Good luck and good night.
I am using the MPMoviePlayerController to play some streaming videos of type .m3u from a url. They video player launches perfectly and the video starts playing perfectly as well, but as soon as I press the Seek Forward or Next or beginSeekingForward button the video complete stops/freezes. After that I can click Done to dismiss the player or scrub the progress bar and it will come back to play to video. But the I can't click on the play/pause or at least seems not to do anything.
I have spent quite sometime looking around online for answer or at least a hint so I can tackle this issue in the right direction but not luck. So, I really hope someone could help with this. Btw, this only happens on iOS 8+, currently I am testing it in iOS 8.1.
This is how I create the player and load the video to it.
NSURL *videoURL = [NSURL URLWithString:self.video.flvurl];
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: videoURL];
self.moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
self.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
self.moviePlayer.shouldAutoplay = NO;
self.moviePlayer.fullscreen = YES;
self.moviePlayer.repeatMode = YES;
self.moviePlayer.view.backgroundColor = [UIColor blackColor];
self.moviePlayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.moviePlayer.view.frame = self.containerView.frame;
[self.view addSubview:self.moviePlayer.view];
[self.moviePlayer prepareToPlay];
[self.moviePlayer play];
I have tried using multiple different notifications to see if I can catch this within one of them, but not luck at all. I have tested all of these notifications so far.. I have added this to the self.moviePlayer and also the self.moviePlayer.view not luck in either of them.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(willResignActive:)
name:UIApplicationWillResignActiveNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoPlaybackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoStartedPlaying:)
name:MPMoviePlayerNowPlayingMovieDidChangeNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoLoadState:)
name:MPMoviePlayerLoadStateDidChangeNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self

object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoPlaybackUserInfoKey:)
name:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey
object:self.moviePlayer.view];
Well, if you need more relevant code please let me know. I really need some help with this.. Thanks in advance.
This code worked for me, but just to get rid of freezing. Sign up for the MPMoviePlayerLoadStateDidChangeNotification, like you did above. In the callback method, I simply set the movie players contentURL to the original URL I had initialized it with at the start, and set the movie player to play again.
The functionality of this is when you tap the NEXT or BACK buttons in fullscreen, the video simply starts playing again from the start. That may not be ideal since the user might not expect this, but at least it will stop it from freezing. I'm currently trying to find a better workaround.
- (void) videoLoadState:(NSNotification *)notification
{
MPMovieLoadState loadState = moviePlayer.loadState;
if(loadState == MPMovieLoadStateUnknown)
{
NSLog(#"Movie Load state is unknown");
moviePlayer.contentURL = currentlyPlayingVideoURL;
[moviePlayer prepareToPlay];
}
}
If you check the value of MPMoviePlaybackState in this method, it will always be MPMoviePlaybackStateStopped when NEXT or BACK are pressed, so I'm not sure how to handle it...
I'm new in iPhone Application Development, and now i faced a problem, can any one tell me how can i play a video randomly without pressing the play button. The video should start automatically while the application launch and play randomly without stopping. I don't have any idea how to do this. I don't have any code also. Please help me any one...
Thanks in advanced.
You could implement it like this:
You need a movie player configured with e.g. a file url and add it to your view
NSURL *url = [[NSBundle mainBundle] URLForResource:movieName withExtension:#"mov"];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
moviePlayer.view.frame = // set the frame
[self.view addSubview:moviePlayer.view];
Start the movie player
[moviePlayer play];
Listen to the notification
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(handleMoviePlayerStatChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:moviePlayer];
Start the video again
- (void)handleMoviePlayerStatChange:(NSNotification *)note {
NSLog(#"mp playback state %i", moviePlayer.playbackState);
if (moviePlayer.playbackState == MPMoviePlaybackStatePaused) {
[moviePlayer play];
}
}
To hide the video controls set the controlStyle property of the movie player instance:
moviePlayer.controlStyle = MPMovieControlStyleNone;
In my application i play video using mpmovieplayercontroller
first set scaling mode to MPmovieScalingmodefill and display video correct to scalingmode.
then after i view video in full screen and exit full screen then not set scaling mode to
MPmovieScalingmodeFill and display video in defualt mode.
below my code for video playing
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(ExitFullScreen:)
name:MPMoviePlayerWillExitFullscreenNotification object:nil];
[appDelegate.moviePlayerController setContentURL:fileURL];
if ([appDelegate checkDevice])
{
[appDelegate.moviePlayerController.view setFrame:CGRectMake(0,0, 320,463)];
}
else
{
[appDelegate.moviePlayerController.view setFrame:CGRectMake(0,0, 320,375)];
}
[appDelegate.moviePlayerController prepareToPlay];
appDelegate.moviePlayerController.scalingMode=MPMovieScalingModeFill;
appDelegate.moviePlayerController.controlStyle=MPMovieControlStyleDefault;
appDelegate.moviePlayerController.shouldAutoplay=NO;
[appDelegate.moviePlayerController setFullscreen:YES animated:YES];
[appDelegate.moviePlayerController play];
[self.view addSubview:appDelegate.moviePlayerController.view];
- (void)ExitFullScreen:(NSNotification *)notification{
NSLog(#"Exit full Screen");
[appDelegate.moviePlayerController setControlStyle:MPMovieControlStyleEmbedded];
[appDelegate.moviePlayerController setScalingMode:MPMovieScalingModeFill];}
so my probleem is how can set scaling mode after exit full screen or do not change scaling mode after exit screen ?
please help me out.
thanks.
This isn't the "ideal" solution, but it works!
Basically, once you exit full screen the MPMoviePlayerController instance gets all screwed up and resetting the scaling property to MPMovieScalingModeFill won't help no matter where or when you do it (I've tried all sorts of stuff and after an hour gave up). Easiest solution is to remove the MPMoviePlayerController and simply allocate a new instance of MPMoviePlayerController each time full screen is exited (not ideal, but totally works):
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:NO];
if (self.moviePlayer != nil)
[self.moviePlayer.view removeFromSuperview];
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:self.videoURL];
self.moviePlayer.view.frame = CGRectMake(#, #, #, #);
self.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
self.moviePlayer.shouldAutoplay = NO;
[self.moviePlayer setContentURL:self.videoURL];
[self.moviePlayer prepareToPlay];
[self.moviePlayer setScalingMode:MPMovieScalingModeFill];
[self.view addSubview:self.moviePlayer.view];
}
PS: Don't forget to call super's viewDidAppear or suffer all sorts of unforeseeable mayhem (a very common mistake in iOS development)
I believe this will generate the MPMoviePlayerScalingModeDidChangeNotification.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(movieScalingModeDidChange:)
name:MPMoviePlayerScalingModeDidChangeNotification
object:nil];
MPMoviePlayerScalingModeDidChangeNotification
Posted when the scaling mode of a movie player has changed. There is no userInfo dictionary. Scaling mode can change programmatically or by user interaction. To set or retrieve the scaling mode of a movie player, access its scalingMode property. The movie player whose state has changed is available as the object associated with the notification.
I use MPMoviePlayerController to play a local file in my Application Document folder which have I have downloaded for a server URL:
itemMoviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[self.view addSubview:itemMoviePlayerController.view];
itemMoviePlayerController.fullscreen = YES;
itemMoviePlayerController.movieSourceType = MPMovieSourceTypeFile;
itemMoviePlayerController.initialPlaybackTime = -1.0;
[itemMoviePlayerController play];
When I play .mov file just after I downloaded it, It shows up a black empty screen & app UI is unusable.
But if play same local file next time, it plays fine.
I even verified playState & localState for MPMoviePlayerController they seems fine.
What could be reason for black empty screen?
You need to retain your instance of MPMoviePlayerController i.e. as a property or an instance variable. The reference to the movie player is lost if you do not retain it.
You could try to put [itemMoviePlayerController prepareToPlay];
before the [itemMoviePlayerController play];
The way preferred by Apple to display an only full screen video is to present a modal MPMoviePlayerViewController (as Hollance said).
To present it, you should use something like :
moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];
[self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];
[itemMoviePlayerController play];
This is documented by Apple here
You can read there that you should keep a reference to your MPMoviePlayerViewController in order to dismiss it later with
[self dismissMoviePlayerViewControllerAnimated:moviePlayerViewController].
I fixed this by putting
#property (strong, nonatomic) MPMoviePlayerController *moviePlayer;
in my .h file, and calling self.moviePlayer in all my code and it worked!
You need to use MPMoviePlayerViewController instead. Notice the word "View" in there.
I hope this will help. I solved this problem in my project
-(void)startPlayingMovie
{
NSLog(#"startPlayingMovie");
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"Start_video" ofType:#"mov"]];
moviePlayer = [[MPMoviePlayerViewController alloc]
initWithContentURL:url];
moviePlayer.view.frame = CGRectMake(0, 0, self.view.bounds.size.height, self.view.bounds.size.width);
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayer.moviePlayer];
moviePlayer.moviePlayer.controlStyle = MPMovieControlStyleNone;
moviePlayer.moviePlayer.shouldAutoplay = YES;
[self presentMoviePlayerViewControllerAnimated:moviePlayer];
[moviePlayer.moviePlayer setFullscreen:YES animated:NO];
NSLog(#"endPlayingMovie");
}
Same thing happened to me. It turns out, I had tried to play the movie while the UIImagePicker wasn't dismissed yet.
In my UIImagePickerDelegate I had to first dismiss the UIImagePicker Popup and then open the ViewController managing the MPMediaPlayerController:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)infoDict
{
//the first thing to do: dismiss the media picker
if ([ipPop isPopoverVisible])
{
[ipPop dismissPopoverAnimated:ANIMATION_SETTING];
}
myMediaPlayerViewController * playerVC = [[myMediaPlayerViewController alloc] initWithMediaDict:infoDict];
[self.navigationController pushViewController:playerVC animated:ANIMATION_SETTING];
}
I had this same problem and it made me crazy. It would work on one view controller fine (audio and video), but not work on another (black screen with just audio). In the end, all I did was CHANGE THE ORDER of the calls: I simply waited until I was done configuring the movie player before adding it to the view. In other words, I called "addSubview" on the line just before the call to "play".
This is the code I'm using to play a file from URL:
MPMoviePlayerViewController *movieViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:contentUrl]];
movieViewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[self presentMoviePlayerViewControllerAnimated:movieViewController];
[movieViewController release];
It seems to work fine for me. Two notes:
Some simulators (like the current iOS 5.0) crash when playing a movie, but it works on a real device
If you leave out the movieSourceType part, a black screen is shown for about a second before the movie starts
I had the same problem, solved it changing the extension of the file being played from .mpg to .mp4. apparently MPMoviePlayerController expects a correct extension, though from the documentation it is not clear to me that this is a requirement:
http://developer.apple.com/library/ios/#documentation/mediaplayer/reference/MPMoviePlayerController_Class/Reference/Reference.html
Supported Formats This class plays any movie or audio file supported
in iOS. This includes both streamed content and fixed-length files.
For movie files, this typically means files with the extensions .mov,
.mp4, .mpv, and .3gp and using one of the following compression
standards:
This issue seems fixed after updating device iOS to 5.0.
Seems to iOS SDK issue for previous version
you must do like that with CGRectMake(0, 0, 0, 0) in the finished callback!
-(void)playMovieAtURL:(NSURL*)theURL
{
MPMoviePlayerController* theMovie=[[MPMoviePlayerController alloc] initWithContentURL:theURL];
theMovie.scalingMode=MPMovieScalingModeAspectFill;
theMovie.view.frame = CGRectMake(2, 246, 317, 70);
[self.view addSubview:theMovie.view];
// Register for the playback finished notification.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(myMovieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:theMovie];
// Movie playback is asynchronous, so this method returns immediately.
[theMovie play];
}
// 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.view.frame = CGRectMake(0, 0, 0, 0);
// Release the movie instance created in playMovieAtURL
[theMovie release];
}
I was having a similar issue. After playback there comes an empty screen, which prevents me to play video again.
Well here is my work around. That way play button doesn't disappear.
[self.movieController stop];
[self.movieController prepareToPlay];
[self.movieController pause];
Also, If you are using http URLs, make sure you disable App Transport Security in your projects *.plist file. It will also cause a black screen.
Add the following code:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key><true/>
</dict>
Here:
[INSERT CODE ABOVE HERE]
</dict>
</plist>
