iOS: MPMoviePlayerController Done button doesn't work - ios

I am adding an MPMoviePlayerController to a view like so:
player = [[MPMoviePlayerController alloc] initWithContentURL:url];
player.controlStyle = MPMovieControlStyleNone;
[player.view setFrame:self.playerView.bounds];
[self.playerView addSubview:player.view];
self.playerView is a small view inside my main view and I have custom buttons that control playback within that same main view. This all works fine.
I have a fullscreen button that works like so:
- (IBAction) btnFullScreenPressed:(id)sender {
[player setFullscreen:TRUE animated:TRUE];
[player setControlStyle:MPMovieControlStyleFullscreen];
}
This works fine, but then when I hit the Done button on the full screen controls, the movie stops playing but does not return to the smaller self.playerView in my view. How can I get it to "un-fullscreen" and return to the smaller self.playerView?
Thanks.

Quite unintuitively you actually have to set the control style to default, i.e.:
- (IBAction) btnFullScreenPressed:(id)sender {
[player setFullscreen:TRUE animated:TRUE];
[player setControlStyle:MPMovieControlStyleDefault];
}
and, of course, then set it back to none when you receive MPMoviePlayerWillExitFullscreenNotification or MPMoviePlayerDidExitFullscreenNotification (I prefer "did exit").

Hide MPMoviePlayerController controls on 1+ plays

I have a MPMoviePlayerController setup:
self.moviePlayerController = [[MPMoviePlayerController alloc] init];
[self.moviePlayerController.view setFrame:frame];
// hide controls initially
[self.moviePlayerController setControlStyle:MPMovieControlStyleNone];
[self.view addSubview:self.moviePlayerController.view];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(loadStateChanged:) name:MPMoviePlayerLoadStateDidChangeNotification object:self.
moviePlayerController];
Then when the notification is fired:
-(void)loadStateChanged:(NSNotification*)notification {
if (self.moviePlayerController.controlStyle == MPMovieControlStyleNone) {
[self.moviePlayerController setControlStyle:MPMovieControlStyleDefault];
}
}
On initial playback this works great, controls are not shown when playback starts but tapping the view shows the controls.
However, when a movie is already playing and I start playback of another URL, I hide the controls, but they reappear after playback starts of the second movie:
[self.moviePlayerController setContentURL:videoURL];
[self.moviePlayerController setControlStyle:MPMovieControlStyleNone];
[self.moviePlayerController play];
The notification does fire again and it correctly has a controlStyle of MPMovieControlStyleNone which I then set to MPMovieControlStyleDefault.
Anybody have any experience with this, is there a way to make sure the controls stay hidden on a second playback, but are in fact visible when the user taps the movie view.
Thanks!

MPMoviePlayerController on iPhone when enter full screen go in pause

i have add MPMoviePlayerController in my project in this way:
player = [[MPMoviePlayerController alloc] init];
[player setContentURL:videoURL];
[self.view addSubview:player.view];
then when i press a button i play the video:
[player play];
all works perfect, but when i press the button to enter in the fullscreen mode the video go in pause and i have to press the play button to continue the playback, anyone know why?
This worked well for me
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
if (!self.moviePlayer.isFullscreen) {
[self.moviePlayer pause];
}
}

After exit full screen MPMoviePlayerController set scaling mode to MPMovieScalingModeFill in ios

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.

How can I remove "Loading..." label from MPMoviePlayerViewController?

I have a MPMoviePlayerViewController, I don't want to initialize it with a content url, I just want to have a empty movie player GUI out there. Whenever I want it to load a movie, it then starts loading. But I can't
self.playerViewController = [[MPMoviePlayerViewController alloc] init];
MPMoviePlayerController *player = [self.playerViewController moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerPlaybackStateChanged:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil];
player.shouldAutoplay = FALSE;
player.initialPlaybackTime = 0;
[player setFullscreen:FALSE];
[player.view setFrame:CGRectMake(0, -20, self.view.bounds.size.width, self.view.bounds.size.height/2)];
[self.view addSubview:player.view];
As you see, I init the MPMoviePlayerViewController with no content url, and I set the autoplay to false, but when I run the application. Even though there is no video url given, I can still see a label "Loading ..." near the "Done" button, why???? How can I remove the loading label?
Just use MPMoviePlayerController instead of MPMoviePlayerViewController. You'll need to build a view controller around it if you want to display it modally.
You could also maybe iterate through [MPMoviePlayerViewController view].subviews until you find the UILabel, but that approach might break in future versions of iOS.

MPMoviePlayerController showing black empty screen

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>
