AVPlayer plays audio but video freezes - ios

I have two UIViewControllers each with an AVPlayer that are supposed to play a video file when they are pushed into a UINavigationController:
-(void)viewWillAppear:(BOOL)animated{
videoView = [[UIView alloc]initWithFrame:self.view.frame];
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"myVideo" ofType:#"mov"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
self.avPlayer = [AVPlayer playerWithURL:fileURL];
AVPlayerLayer *foregroundLayer = [AVPlayerLayer playerLayerWithPlayer:self.avPlayer];
self.avPlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone;
foregroundLayer.frame = self.view.frame;
foregroundLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;
[videoView.layer addSublayer:foregroundLayer];
[self.view addSubview:videoView];
self.avPlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone;
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[self.avPlayer currentItem]];
}
-(void)viewDidAppear:(BOOL)animated{
[self.avPlayer play];
}
-(void)playerItemDidReachEnd:(NSNotification *)notification {
[self.navigationController popViewControllerAnimated:NO]
}
The first time I push any of the UIViewControllers the playback works well. But after that, if I push any of them again the sound plays but the video freezes.
I've tried using a MPMoviePlayerViewController but the behavior is the same. Any thoughts?

AVPlayerItemDidPlayToEndTimeNotification not working

NSURL *videoURL = [[NSBundle mainBundle] URLForResource:#"thoughtcastAnimate_v02" withExtension:#"mov"];
// create an AVPlayer
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
// create a player view controller
AVPlayerViewController *controller = [[AVPlayerViewController alloc]init];
controller.showsPlaybackControls = false;
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(itemDidFinishPlaying) name:AVPlayerItemDidPlayToEndTimeNotification object: player];//edited
controller.player = player;
// show the view controller
[self addChildViewController:controller];
[self.view addSubview:controller.view];
controller.view.frame = self.view.frame;
[player play];
itemDidFinishPlaying is never called ?!
I don't understand why.
Perhaps I have an invalid NSNotificationCenter issue. Or maybe one of it's parameters. Unsure.

AVPlayer not showing FullScreen

I am working on playing a recorded video recorded by AVCapture.I am saving the video URL in string named outputFileURL. I tried playing back the video using AVPlayerLayer concept. The code I used is
AVPlayer *avPlayerq = [AVPlayer playerWithURL:outputFileURL];
avPlayerq.actionAtItemEnd = AVPlayerActionAtItemEndNone;
AVPlayerLayer *videoLayer = [AVPlayerLayer playerLayerWithPlayer:avPlayerq];
videoLayer.frame= self.view.bounds;
[self.view.layer addSublayer:videoLayer];
[avPlayerq play];
But the video I am getting is not full screen.
Can anyone can help me to solve?
I added the following code and I am able to get the full screen.
videoLayer.videoGravity=AVLayerVideoGravityResizeAspectFill;
Hope this may help.
AVPlayer *player = [[AVPlayer alloc] initWithURL:url];
AVPlayerViewController *playerViewController = [AVPlayerViewController new]; playerViewController.delegate = self;
playerViewController.player = player;
[playerViewController.player play];
[self presentViewController:playerViewController animated:YES completion:nil];
Try This
Ok than you have to use MPMoviePlayerController
NSString *path = [[NSBundle mainBundle] pathForResource:#"Video_Intro" ofType:#"mov"];
moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:[NSURL fileURLWithPath:path]];
moviePlayer.view.frame = ivVideoThumbnail.frame;
//moviePlayer.view.top += 20; // Add to fix 20 pixel diff of moviePlayer view
// Register this class as an observer instead.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayer];
[svIntro addSubview:moviePlayer.view];
moviePlayer.fullscreen = true;
[moviePlayer play];
Also implement Observer method
-(void)movieFinishedCallback:(id)mPlayer
{
[moviePlayer.view removeFromSuperview];
}

How to : Local MP4 Video as Background in iOS App Objective C iOS 8

I try to use a simple 13 sec mp4 video as background loop for my login screen.
I want the Video to autoplay and loop. It has no Audio and I don´t need controls.
I need buttons and other objects in front of it.
I tried to use a WebView and make the MP4 a GIF file from this Tutorial : https://medium.com/swift-programming/ios-make-an-awesome-video-background-view-objective-c-swift-318e1d71d0a2
But the problem is that my 5 MB MP4 has (converted to a GIF) a size of 95 MB.
I can´t use this method.
Is there any "Easy to Use" way ?
EDIT :
Okay this is what I did now.
I imported AVFoundation.
This is the Code in the View
- (void)viewDidLoad {
[super viewDidLoad];
NSURL* mURL = [[NSBundle mainBundle] URLForResource:#"App-BG-Loop" withExtension:#"mp4"];
AVPlayer* player = [AVPlayer playerWithURL:mURL];
player.actionAtItemEnd = AVPlayerActionAtItemEndNone;
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[player currentItem]];
AVPlayerLayer* playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
playerLayer.frame = _videoView.bounds;
playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;
playerLayer.needsDisplayOnBoundsChange = YES;
[_videoView.layer addSublayer:playerLayer];
_videoView.layer.needsDisplayOnBoundsChange = YES;
[player play];
// Do any additional setup after loading the view, typically from a nib.}
- (void)playerItemDidReachEnd:(NSNotification *)notification {
AVPlayerItem *p = [notification object];
[p seekToTime:kCMTimeZero];}
This works great in the iOS Simulator but when I try to start it on a device it wont start and or play the video. The View just stays white. No Error nothing.
Any Idea?
EDIT 2 :
Problem with not playing on device was the size of the video it was to big. Apple only supports 1080p on the devices.
I recently had to use an animation too. I tried it with a UIImageView first but the memory management was not too good with that. I ended up making a .mp4 from it and use it in a MPMoviePlayerController:
-(void)setupDashboardAnimation
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(checkMovieStatus:)
name:MPMoviePlayerLoadStateDidChangeNotification
object:nil];
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:#"some_movie" ofType:#"some_extention"];
NSURL *movieURL = [NSURL fileURLWithPath:moviePath];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
_backgroundAnimationMoviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
_backgroundAnimationMoviePlayer.controlStyle = MPMovieControlStyleNone;
_backgroundAnimationMoviePlayer.repeatMode = MPMovieRepeatModeOne;
_backgroundAnimationMoviePlayer.view.backgroundColor = [UIColor clearColor];
for (UIView *aSubView in _backgroundAnimationMoviePlayer.view.subviews)
{
aSubView.backgroundColor = [UIColor clearColor];
}
[_backgroundAnimationMoviePlayer.view setFrame:imv_background.frame];
[_backgroundAnimationMoviePlayer prepareToPlay];
}
-(void)checkMovieStatus:(NSNotification *)notification
{
if (_backgroundAnimationMoviePlayer.loadState & (MPMovieLoadStatePlayable | MPMovieLoadStatePlaythroughOK) && _backgroundAnimationMoviePlayer.playbackState != MPMoviePlaybackStatePlaying)
{
[self.view insertSubview:_backgroundAnimationMoviePlayer.view aboveSubview:imv_background];
[_backgroundAnimationMoviePlayer play];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerLoadStateDidChangeNotification
object:nil];
dashboardAnimationDidSetup = YES;
}
}

Call MPMoviePlayerViewController in app delegate

I am using story board in app.
Using storyboard all views are connected properly
Now new thing I want to do is,
When my Splash screen goes down, I want to show 3 sec video every time user opens the app.
I know how to load video from viewcontroller,
Following is code that I used to launch the video.
- (void)showVideo
{
[super viewDidLoad];
// Do any additional setup after loading the view.
NSString *path = [[NSBundle mainBundle] pathForResource:#"video" ofType:#"mp4"];
NSURL *url = [NSURL fileURLWithPath:path];
NSLog(#"video path :- %#",url);
videoController = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
videoController.moviePlayer.controlStyle = MPMovieControlStyleNone;
[self presentMoviePlayerViewControllerAnimated:videoController];
[videoController.moviePlayer play];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:videoController];
}
- (void) moviePlayBackDidFinish:(NSNotification*)_notification
{
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
[videoController.view removeFromSuperview];
[videoController.moviePlayer stop];
videoController = nil;
[self.view removeFromSuperview];
}
But when I use this code in my rootViewController app crashes saying
Attempt to present <MPMoviePlayerViewController:> on <DashbaordVC:> whose view is not in the window hierarchy
But when I use same code in other demo app using navigation controller (No Storyboard) it works fine.
But in this app where story board is used, it crashes.
Also I tried
[self.navigationController pushViewController:self.videoController animated:NO];
Then I thought of adding this code in AppDelegate file and calling the method from ApplicationDidFinishLaunching
But didn't help.
can anyone guide me.... for the same
Also how to add MPMoviePlayerViewController in app delegate.
I think you can do this by MPMoviePlayerController. Try following code
NSString *path = [[NSBundle mainBundle] pathForResource:#"video" ofType:#"mp4"];
NSURL *url = [NSURL fileURLWithPath:path];
videoPlayer = [[MPMoviePlayerController alloc] init];
[videoPlayer.view setFrame:CGRectMake(0.0, viewTopbar.frame.size.height,[UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height - (viewTopbar.frame.size.height + 50.0))];
[videoPlayer setMovieSourceType:MPMovieSourceTypeFile];
[videoPlayer setContentURL:url];
[videoPlayer setControlStyle:MPMovieControlStyleEmbedded];
[videoPlayer setScalingMode:MPMovieScalingModeNone];
[videoPlayer prepareToPlay];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:videoPlayer];
[self.view addSubview:videoPlayer.view];
[videoPlayer play];
And if you dont want full screen then used it like this
[videoPlayer setControlStyle:MPMovieControlStyleNone];

MPMoviePlayerViewController -- how to eliminate black flash when video loads?

I'm using MPMoviePlayerViewController to show a video in my app. It works! Only problem is that there's a black flash just before the movie plays.
How can I get rid of the black flash? I've seen other threads, but they don't seem to have an explanation that works with MPMoviePlayerViewController and is sufficiently specific/detailed for a novice like me (most are for MPMoviePlayerController).
Would really appreciate any help!
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"aiw_intro_video" ofType:#"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] init];
mpvc.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
mpvc.moviePlayer.controlStyle = MPMovieControlStyleNone;
[mpvc.moviePlayer setContentURL:fileURL];
[mpvc.moviePlayer play];
[self presentViewController:mpvc animated:NO completion:NULL];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:mpvc.moviePlayer];
After endlessly iterating and tweaking, I stumbled my way into a solution using MPMoviePlayerController.
Don't forget to declare the property in the .h file, e.g.
#property (strong, nonatomic) MPMoviePlayerController *moviePlayer;
Then
// Add default image to smooth transition
UIImage *myImage = [UIImage imageNamed:#"aiw_launch1136_black.png"];
self.videoStartFrame.image = myImage;
// Play the intro video
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"aiw_intro_video" ofType:#"mp4"]]];
self.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
self.moviePlayer.controlStyle = MPMovieControlStyleNone;
[self.moviePlayer prepareToPlay];
[self.moviePlayer play];
[self.moviePlayer.view setFrame:self.view.bounds];
[self.view addSubview:self.moviePlayer.view];
self.moviePlayer.view.hidden = YES;
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(isMovieReady:) name:MPMoviePlayerLoadStateDidChangeNotification object:self.moviePlayer];
// Detect that the video is ready and unhide the view
-(void)isMovieReady:(NSNotification *)notification {
MPMoviePlayerController *moviePlayer = [notification object];
if(moviePlayer.loadState & (MPMovieLoadStatePlayable | MPMovieLoadStatePlaythroughOK))
{
self.moviePlayer.view.hidden = NO;
}
}
