I want to play mp4 video files using MPMoviePlayerController.
Here is the code I am currently using:
NSURL *url = [NSURL URLWithString:
videoLink];
MPMoviePlayerController *controller = [[MPMoviePlayerController alloc ]init];
[controller`enter code here` prepareToPlay];
self.mp = controller; //Save obj reference
Also I am re using same player object because have to load another video file as soon as next or previous clicked on UI.
controller.view.frame = CGRectMake(0, yMargin, self.view.frame.size.width, self.view.frame.size.width*9/16); //Set the size
[self.view addSubview:controller.view];//Show the view
[controller setContentURL:url];
[controller play]; //Start playing
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification object:self.mp ];
Sometimes it's loading video properly but randomly showing an error message as given below.
itemFailedToPlayToEnd: {
kind = 1;
new = 2;
old = 0;
}
If error comes it doesn't load any other video afterwards at least for next 15(approx.) attempts.This behaviour is very random as sometimes it keeps showing the error in log and player doesn't load the video at all.
Has someone else faced this similar issue ? I found many questions posted related to this problem but nothing seems to be working for me.
Other solution i found playing a video using web view but auto play
doesn't work for web view.
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.
An MPMoviePlayerViewController which is presented modally through presentMoviePlayerViewControllerAnimated: automatically dismisses itself when it's content finishes playing.
I've tried to disable this, since I want to play other content afterwards. However, even if I register to the NSNotificationCenter with [[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(movieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification object:playerVC.moviePlayer]; and set some other content, it still dismisses.
How can I stop MPMoviePlayerViewController from automatically dismissing itself?
UPDATE:
As a clarification, this question is only about removing the automatic dismissal and not about dealing with the disabled 'done' button. The selected answer reflects. This is by design, since we assume the developer adds their own means of dismissing the MPMoviePlayerViewController. However, #bickster's answer deals with the 'done' button as well.
Thanks to this blog article I figured out that MPMoviePlayerViewController automatically registers itself to the NSNotificationCenter upon creation. You have to first remove this registration and it will stop dismissing itself automatically.
// Initialize the movie player view controller with a video URL string
MPMoviePlayerViewController *playerVC = [[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:aVideoUrl]] autorelease];
// Remove the movie player view controller from the "playback did finish" notification observers
[[NSNotificationCenter defaultCenter] removeObserver:playerVC name:MPMoviePlayerPlaybackDidFinishNotification object:playerVC.moviePlayer];
You can use this code to stop the viewcontroller from automatically dismissing and capture the event when the user clicks the "Done" button so you can dismiss the viewcontroller yourself.
Step 1. - alloc a MPMoviePlayerViewController
videoPlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[[NSURL alloc ]initWithString:[aURL];
Step 2. - Remove the default MPMoviePlayerPlaybackDidFinishNotification observer and add your own
[[NSNotificationCenter defaultCenter] removeObserver:videoPlayer
name:MPMoviePlayerPlaybackDidFinishNotification object:videoPlayer.moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:videoPlayer.moviePlayer];
Step 3. - Present viewcontroler
[self presentMoviePlayerViewControllerAnimated:videoPlayer];
Step 4. - Add videoFinish: method
-(void)videoFinished:(NSNotification*)aNotification{
int value = [[aNotification.userInfo valueForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] intValue];
if (value == MPMovieFinishReasonUserExited) {
[self dismissMoviePlayerViewControllerAnimated];
}
}
You can try something like this.
when the mpmovieplayercontroller finishes playing a video and you recieve the notification in your method movieFinishedCallback: implemect
[playerVC.movieplayer setContentURL:// set the url of the file you want to play here];
[playerVC.moviePlayer play];
Hope this helps
Since "Done" button is not working anymore if I remove MPMoviePlayerPlaybackDidFinishNotification from NSNotificationCenter, I change repeat mode to MPMovieRepeatModeOne.
Then, everything's working fine except the video is repeated.
MPMoviePlayerViewController *playerVC = [[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:aVideoUrl]] autorelease];
[playerVC.moviePlayer setRepeatMode:MPMovieRepeatModeOne];
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>

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").
