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

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;
}
}

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];
}

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];

AVPlayer plays audio but video freezes

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?

MPMoviePlayerController gives me a black empty view,no video playing

iOS 5.1 ,here is the code:
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL: [NSURL URLWithString:#"map.mp4"]];
[player prepareToPlay];
[player.view setFrame: self.view.bounds]; // player's frame must match parent's
[self.view addSubview: player.view];
// ...
[player play];
in fact ,this is just the same as the apple reference say,but when I click the button to use this function,there is just a black Rectangle stay there,no vedio playing ,no sound happening,and no crush,so I want to know how to make this work
Sorry for very late reply. The Solution is kind of wierd. But it helped me keep going while facing the same issue.
MPMovieSourceTypeStreaming is the thing you have missed.
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL: [NSURL URLWithString:#"map.mp4"]];
[player prepareToPlay];
[player.view setFrame: self.view.bounds]; // player's frame must match parent's
player.movieSourceType = MPMovieSourceTypeStreaming;
[self.view addSubview: player.view];
// ...
[player play];
You may be sending your
[player play]
message too soon.
Use the following notification observation
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(playMovie:) name:MPMoviePlayerLoadStateDidChangeNotification object:player];
To listen for the loadState to change to playable. To check for that update do this :
- (void)playMovie:(NSNotification *)notification {
MPMoviePlayerController *player = notification.object;
if (player.loadState & MPMovieLoadStatePlayable)
{
NSLog(#"Movie is Ready to Play");
[player play];
}
}
The movie should begin playing once it's ready.
Try this below code for play video from your project Resource :
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:#"map" ofType:#"mp4"];
NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain];
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL:movieURL];
[player prepareToPlay];
[player.view setFrame: self.view.bounds]; // player's frame must match parent's
[self.view addSubview: player.view];
// ...
[player play];
Thanks..!
Building on #Dinesh's answer, your URL creation is incorrect. The value of
[NSURL URLWithString:#"map.mp4"]
will be nil since #"map.mp4" is not a valid URL. To create a valid url from the app's bundle do what Dinesh says. To create a remote URL you would do something like
[NSURL URLWithString:#"http://www.jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v"]
The URL should contain all it's parts: protocol, host, path, file.
Cheers, Felipe
Add your movie player controller view on main windows like:
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL: [NSURL URLWithString:#"map.mp4"]];
[player prepareToPlay];
[player.view setFrame: self.view.bounds];
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate.window addSubview: player.view];
[player play];
Hope so it will work!
Your player should be a property of your view controller, something like this:
.h:
#property(nonatomic,weak)MPMoviePlayerController *moviePlayer;
.m:
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL: [NSURL URLWithString:#"map.mp4"]];
[player prepareToPlay];
[player.view setFrame: self.view.bounds]; // player's frame must match parent's
//set the player to your property
self.moviePlayer=player;
[self.view addSubview: self.moviePlayer.view];
// ...
[self.moviePlayer play];
Please use MPMoviePlayerViewController Because of MP4 file. When you use MOV then working perfect!!
MPMoviePlayerViewController *moviePlayerViewController;
-(void)PlayVideoController:(NSString*)videoUrl1 {
NSURL *fileURL = [NSURL URLWithString:videoUrl1];
moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];
// Register for the playback finished notification.
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(myMovieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerViewController.moviePlayer];
//Present
[self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];
// Play the movie!
moviePlayerViewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[moviePlayerViewController.moviePlayer play];
}
-(void)myMovieFinishedCallback:(NSNotification*)aNotification {
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerViewController.moviePlayer];
[moviePlayerViewController release], moviePlayerViewController = nil;
}
You might want to cross check video url for blank spaces. Following code works for me.
- (IBAction)btnPlayVideo:(id)sender {
self.strVideoUrl = [self.strVideoUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *fileURL = [NSURL URLWithString:[NSString stringWithFormat:#"%#", self.strVideoUrl]];
NSLog(#"Url to play = %#", self.strVideoUrl);
self.moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayerController];
[self.moviePlayerController.view setFrame:self.view.bounds];
[self.view addSubview:self.moviePlayerController.view];
self.moviePlayerController.shouldAutoplay = YES;
self.moviePlayerController.fullscreen = YES;
self.moviePlayerController.controlStyle=NO;
[self.moviePlayerController prepareToPlay];
self.moviePlayerController.movieSourceType = MPMovieSourceTypeStreaming;
[self.moviePlayerController play];
}
- (void)moviePlaybackComplete:(NSNotification *)notification
{
self.moviePlayerController = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayerController];
[self.moviePlayerController.view removeFromSuperview];
self.closeVideAdProp.hidden = NO;
btnCloseAd.hidden=FALSE;
}

ShouldAutoplay on MoviePlayerController

I am a new developer, therefore I'm still learning and know I'm doing some things wrong. I have a segmented control object in which when the user presses one of the segments, it goes to play a video. I have it setup to where they press the segment, then have to press a play button to get the video to play. I want to cut out the play button and have it play automatically. This is where I'm having trouble. I found the shouldAutoplay option but when I use it and cut out the button, it won't take me to the video at all. I'm sure I'm not using the shouldAutoplay option correctly. Was hoping for some help or at least a point in the right direction.
- (IBAction)playMovie:(id)sender;
{
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:#"mytestimony" ofType:#"m4v"];
NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain];
MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
theMovie.shouldAutoplay = YES;
theMovie.scalingMode = MPMovieScalingModeAspectFill;
[theMovie autorelease];
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
[self presentMoviePlayerViewControllerAnimated:moviePlayer];
}
Have you tried [theMovie play];?
UPDATE: I just noticed you set shouldAutoplay in theMovie, but what you presented is another instance of MPMoviePlayerViewController, which is moviePlayer. That's why your movie did not autoplay. You should instead have:
[self presentMoviePlayerViewControllerAnimated:theMovie];
Don't play the video, just prepare it for playing and put the shouldAutoPlay as NO, because you don't want to video player to play it automatically.
-(void) SetVideoFile:(NSString *)fileName {
videoFileName=fileName;
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:fileName]];
moviePlayer.initialPlaybackTime = 0;
moviePlayer.view.frame = self.view.frame ;
[orientationHandler VideoStart];
[self.view addSubview:moviePlayer.view] ;
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayer];
moviePlayer.shouldAutoplay = NO;
[moviePlayer prepareToPlay];
}
-(void)moviePlaybackDidFinish:(NSNotification *)notification {
// your custom code which you want to play after the player did finish playing
}
