Loading the same ViewController after watching MPMoviePlayerController - objective-c

I have a ViewController which displays the information about the selected show, and the play button of the MPMoviePlayerController is there. Now, the issue is when I clicked on the full screen of the player then clicked done. It is supposed to go back to the ViewController which displays the info, but it isn't. But it is going in to the viewDidLoad of the ViewController and it doesn't display anything at all. I feel like something is on the top of the ViewController or something like that
Here's how I remove the player controller
- (void)dealloc
{
self.delegate = nil;
self.activityIndicator = nil;
[self deregisterMoviePlayerNotifications];
[self.player.view removeFromSuperview];
[self removeFromSuperview];
[self stopVideo];
self.player = nil;
}

You should use AVPlayerViewController as MPMoviePlayerController is deprecated. You can use this code on play button
-(void)playButton{
AVPlayer *player = [[AVPlayer alloc]initWithURL:urlVideo];
AVPlayerViewController *controller = [[AVPlayerViewController alloc]init];
controller.player = player;
controller.videoGravity = AVLayerVideoGravityResizeAspectFill;
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(playerItemDidReachEnd:) name:AVPlayerItemDidPlayToEndTimeNotification object:player.currentItem];
controller.videoGravity = AVLayerVideoGravityResizeAspect;
[self presentViewController:controller animated:YES completion:nil];
[player play];
}
-(void)playerItemDidReachEnd:(NSNotification*)notification{
[[NSNotificationCenter defaultCenter] removeObserver:self];
[self dismissViewControllerAnimated:YES completion:nil];
}
Note : Don't forget to add AVFoundation.framework.

playerItemDidReachEnd moves to wrong ViewController

My app has a start page and a second page with buttons that play videos. When a video is finished the AVPlayer is dismissed with playerItemDidReachEnd. But for some reason it shows the start page and not the second page when the player is dismissed. How can I get it to show the second page instead?
#import "ViewController.h"
#import AVKit;
#import AVFoundation;
#interface ViewController ()
#property(nonatomic, readonly) AVPlayerItem *currentItem;
#end
#implementation ViewController
AVPlayerViewController *playerViewController;
- (void)viewDidLoad {
[super viewDidLoad];
playerViewController = [[AVPlayerViewController alloc] init];
}
-(void)playerItemDidReachEnd:(NSNotification *) notification {
//remove the player
[self dismissViewControllerAnimated:NO completion:nil];
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
- (IBAction)playVideo:(id)sender {
NSURL *url = [NSURL URLWithString:#"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"];
AVURLAsset *asset = [AVURLAsset assetWithURL: url];
AVPlayerItem *item = [AVPlayerItem playerItemWithAsset: asset];
AVPlayer * player = [[AVPlayer alloc] initWithPlayerItem: item];
playerViewController.player = player;
UIScreen *mainScreen = [UIScreen mainScreen];
CGRect viewRect = mainScreen.bounds;
playerViewController.view.frame = viewRect;
playerViewController.showsPlaybackControls = YES;
[self.view addSubview:playerViewController.view];
[player play];
/* When the player item has played to its end time we'll dismiss the controller */
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:playerViewController.player.currentItem];
}
#end
If I understand your code correctly, your "second page" is ViewController.
You are adding AVPlayerViewController by [self.view addSubview:playerViewController.view];, so you need to remove this view by calling
[playerViewController.view removeFromSuperview].
After [self dismissViewControllerAnimated:NO completion:nil];, you dismiss whole ViewController, not only AVPlayerViewController.

MPMoviePlayerController cannot be removed using removeFromSuperView

I need to remove a MPMoviePlayerController from a View.
I tried this.
[moviePlayerController stop];
[moviePlayerController.view removeFromSuperview];
the video stops, but the view is not removed. I guess [moviePlayerController.view removeFromSuperview]; does not work. What could be the reason ? Any Solution to this prolem ..?
Thanks.
This problem generally occurs because of the player get deallocated.The solution is that declare the player instance in .h with property "strong".
#property (nonatomic,strong) MPMoviePlayerController* mpController;
Its a known problem that id you are using ARC, then you HAVE TO add the player to your .h because it does still get released if you declare it locally.
#property (nonatomic, strong) MPMoviePlayerController* controller;
To add the view:
self.controller = [[MPMoviePlayerController alloc] initWithContentURL:YOURVIDEOURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.controller];
self.controller.controlStyle = MPMovieControlStyleDefault;
self.controller.shouldAutoplay = YES;
[self.view addSubview:self.controller.view];
[self.controller setFullscreen:YES animated:YES];
And then to remove the view:
- (void) moviePlayBackDidFinish:(NSNotification*)notification {
if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))
{
[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationPortrait animated:NO];
}
MPMoviePlayerController *player = [notification object];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
if ([player
respondsToSelector:#selector(setFullscreen:animated:)])
{
[player.view removeFromSuperview];
}
}
Not entirely sure, but since I had the problem of the movieplayer not showing up because of auto deallocating, I guess you could just set moviePlayerController = nil;.
Not Totally sure if the view will disappear, but worth a try!
Try dismissViewController:animated: That will probably work.
[moviePlayerController stop];
[moviePlayerController setContentURL:nil];
[moviePlayerController.view removeFromSuperview];
this is running well in my project
For me, I tried all of these:
[moviePlayer stop];
[moviePlayer setContentURL:nil];
[moviePlayer.view removeFromSuperview];
moviePlayer = nil;
And nothing worked. I figured out it had to due with my MPMoviePlayerController entering full screen. The fix?
[moviePlayer setFullscreen:NO animated:YES];

ios sdk attach and play video file in view controller before attaching tab bar to main window

I have an non ARC project. So i am maintaining its memory management. It has an tabbar and navigation controller.In that on launch before showing tab bar i have to show an launch video of 5 sec kind of thing. so i have two question
Best and easy way to show an view controller before attaching tab bar controller to main window without leaks.Following is my current technique and code but code analyzer is showing me potential leaks in my video controller.
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
UIViewController *viewController = [[MyViewController alloc] initWithNibName:#"MyViewController" bundle:nil] ;
myNavigationController = [ [ UINavigationController alloc ] initWithRootViewController: viewController ];
[viewController release];
NSMutableArray *viewControllers;
viewControllers = [[NSMutableArray alloc] init];
[viewControllers addObject: myNavigationController]; //Tab 1
myNavigationController release];
// ADD Tab 2 //ADD Tab 3 //ADD Tab 4
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
self.tabBarController.viewControllers = viewControllers;
[viewControllers release];
//Add video contoller before showing tabs
self.videoController = [[VideoPlayViewController alloc] initWithNibName:#"VideoPlayViewController" bundle:nil];
[self.window addSubview:videoController.view];
[self.window makeKeyAndVisible];
Here is my Video Player controller code
- (void)viewDidLoad
{
[super viewDidLoad];
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:#"some url"];
//------ init code in between and added observer to movie playback finish callback ------
[self.view addSubview:moviePlayer.view ]; //show potential leak here if i not release moviePlayer
//[moviePlayer release]; //if i release here controller show me black window with no video playing
}
- (void) moviePlayBackDidFinish:(NSNotification*)notification {
MPMoviePlayerController *player = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerDidExitFullscreenNotification
object:nil];
[player stop];
[player.view removeFromSuperview];
[player release]; //show incorrect decrement of reference count of an object that is not owned at this point by caller
//Fire notification to add tab bar as root view controller
}
And after video is played i get notificaton in my appdelegate and then
[videoController.view removeFromSuperview];
[self.videoController release];
self.videoController = nil;
self.window.rootViewController = self.tabBarController;
and my main app delegate dealloc as usual
- (void)dealloc {
[_window release];
[_tabBarController release];
[super dealloc];
}
i think i explained my problem correctly.Please anyone have any better way to do this.
Thanks
Declare the moviePlayer variable outside of viewDidLoad and then release it in moviePlayBackDidFinish. You're adding a reference to it and then removing only that reference. The reason you're being notified about a leak is that moviePlayer is never released - and with the current setup of your code you can't release it.
MPMoviePlayerController *moviePlayer; //keep reference to moviePlayer
- (void)viewDidLoad
{
[super viewDidLoad];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:#"some url"];
[self.view addSubview:moviePlayer.view ];
}
- (void) moviePlayBackDidFinish:(NSNotification*)notification {
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerDidExitFullscreenNotification
object:nil];
[moviePlayer stop];
[moviePlayer.view removeFromSuperview];
[moviePlayer release];
}

Programmatically show controls in MPMoviePlayerController

I have a MPMoviePlayerController subclass that should show the controls when playback is finished. I have attached a responder to the MPMoviePlayerPlaybackDidFinishNotification notification and tried setting the control style as follows:
[self setControlStyle:MPMovieControlStyleEmbedded];
This is not working. In essence, at the end of the video I want to controls to show.
How can I show controls programatically?
NOTE: The controller is NOT in fullscreen mode.
Kindly find my full Code about this , it's working with me
add .h class add this
#property(strong,nonatomic) MPMoviePlayerViewController * moviePlayer;
at .m class add this code "pass the movie URl"
-(void) playMovie:(NSString *)filePath
{
NSURL *theOutputURL = [NSURL fileURLWithPath:filePath];
if(_moviePlayer)
[_moviePlayer.moviePlayer setContentURL:theOutputURL];
else
_moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:theOutputURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(myMovieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:_moviePlayer.moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerPlaybackStateDidChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:_moviePlayer.moviePlayer];
if (![_moviePlayer.moviePlayer isPreparedToPlay])
[_moviePlayer.moviePlayer prepareToPlay];
_moviePlayer.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[_moviePlayer.moviePlayer setFullscreen:YES];
_moviePlayer.moviePlayer.controlStyle=MPMovieControlStyleEmbedded;
[_moviePlayer.moviePlayer setContentURL:theOutputURL];
_moviePlayer.view.frame = CGRectMake(0, 0, [[UIScreen mainScreen]bounds].size.width, [[UIScreen mainScreen]bounds].size.height);
[_moviePlayer shouldAutorotateToInterfaceOrientation: AVCaptureVideoOrientationLandscapeRight];
[self.view addSubview:_moviePlayer.view];
}
- (void) moviePlayerPlaybackStateDidChange: (NSNotification *) notification {
if (_moviePlayer.moviePlayer.playbackState == MPMoviePlaybackStateStopped) {
[_moviePlayer.moviePlayer setContentURL:[_moviePlayer.moviePlayer contentURL]];
[_moviePlayer.moviePlayer play];
}
}
-(void)myMovieFinishedCallback:(NSNotification*)aNotification
{
// to add your code after playback is finished
}

MPMoviePlayerController problems on iPad

I'm trying to use the MPMoviePlayerController class on the iPad.
Here's my code:
multimediaPlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:path]];
multimediaPlayer.movieControlMode = MPMovieControlModeDefault;
[multimediaPlayer play];
and this works very well on the iPhone but it don't want to run on the iPad. I hear the sound of the video, but the movie doesn't playing.
Why it can be this problem?
Below code working perfect for my application. Hope it would do same for you.
The main thing is to set the frame of mpMoviePlayerController's frame. if you don't do it, it would almost not show the video.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[UIApplication sharedApplication] setStatusBarHidden:YES];
// Register to receive a notification when the movie has finished playing.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
// Register to receive a notification when the movie scaling mode has changed.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(movieScalingModeDidChange:)
name:MPMoviePlayerScalingModeDidChangeNotification
object:nil];
kDomain = [NSString stringWithString:#"http://www.virtua-book.com/"];
[navigationController setNavigationBarHidden:YES];
NSURL *ur=[[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:#"IPAD" ofType:#"mp4"]];
mpMCtr=[[MPMoviePlayerController alloc] initWithContentURL:ur];
mpMCtr.fullscreen=YES;
[mpMCtr setScalingMode:MPMovieScalingModeFill];
[mpMCtr setShouldAutoplay:YES];
[mpMCtr setControlStyle:MPMovieControlStyleNone];
[mpMCtr setMovieSourceType:MPMovieSourceTypeFile];
mpMCtr.view.frame = CGRectMake(0, 0, 1024, 768);
[mpMCtr setRepeatMode:MPMovieRepeatModeNone];
[mpMCtr play];
[ur release];
// Override point for customization after app launch
[navigationController.view addSubview:mpMCtr.view];
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
return YES;
}
// Notification called when the movie finished playing.
- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
[mpMCtr.view removeFromSuperview];
}
To fix back/forward (or previous/next) buttons you should do the following:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerPlaybackStateDidChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil];
...
- (void) moviePlayerPlaybackStateDidChange: (NSNotification *) notification {
if (moviePlayer.playbackState == MPMoviePlaybackStateStopped) {
[moviePlayer setContentURL:[moviePlayer contentURL]];
[moviePlayer play];
}
}
Something along these lines is probably what you want to do:
MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] initWithContentUrl:movieUrl];
[self presentMoviePlayerViewController:mpvc];
MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc]initWithContentURL:movieURL];
mp.moviePlayer.controlStyle = 2;
Ok, guys, I found that this: is deprecated.
The solution is multimediaPlayer.controlStyle = MPMovieControlStyleDefault; but it still doesn't work.
