I have any number of thumbnail images that, when tapped, will play a different video (fullscreen). I have never been clear on whether I should keep one MPMoviePlayerController object in my view controller and have it play whichever url according to the thumbnail that was tapped, or create a new MPMoviePlayerController each time. What is the best practice?
I am also having problems where tapping on different thumbs crashes the app, I believe because the MPMoviePlayerController tries to stream a video while it is already trying to stream. There seems to be no way to cancel a MPMoviePlayerController and clear out what it was doing, then start loading a new video.
Here's how I create it:
MPMoviePlayerController* moviePlayer = [[MPMoviePlayerController alloc] init];
self.player = moviePlayer;
[moviePlayer release];
Then to play a video I do this:
//would like to do something like this first - [self.player clear];
self.player.contentURL = someURL;
[self.view addSubview:player.view];
[self.player prepareToPlay];
[self.player play];
Any advice is welcome... thanks.
When you are changing the video in an MPMovieplayerController,then you can remove the mpmoviecontrollerplayer view from super view using removeFromSuperView and again add it's subview to the super view initializing it with new URL.
No need to create new object every time.

When i'm trying to play a movie on my iPhone, it isn't work. I dont know why.. searched here and all over the internet, try 5 different codes, but still can't get it to work. I'm new to Obj-C, so please be patient.
I just want the movie to play and when the movie is done, to exit the player. also, at the beginning I dont want it to show a black screen, I want to see the first frame of the video instead. is it possible?
-(void)playTheMovie
{
NSURL *url = [NSURL URLWithString:[[NSBundle mainBundle] pathForResource:#"C061381" ofType:#"mp4" inDirectory:#""]];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:url];
[[player view] setFrame:[self.view bounds]]; // Frame must match parent view
[self.view addSubview:[player view]];
[player play];
}
Thanks!
Most probably you are messing up with the URL.
Check out Movie player sample project from apple
https://developer.apple.com/library/ios/#samplecode/MoviePlayer_iPhone/Introduction/Intro.html
Run it first to confirm its functionality and then
Replace its movie with yours and change the extension and path name in the code
if it works copy the code to your project..
I have in my app a tab view with many tabs, and in one of them I have a button that when is clicked, I want to show a movie stream in a view. I have this code:
NSString *moviePath = #"http://10.0.0.4/prog_index.m3u8";
theMovie = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:moviePath]];
[theMovie.view setFrame:CGRectMake(0, 0, (self.view.frame.size.width), (self.view.frame.size.height))];
theMovie.view.backgroundColor = [UIColor grayColor];
theMovie.view.tag = 9999;
[self.view addSubview:[theMovie view]];
[theMovie play];
The view appears, but the video doesn't start. What is wrong?
You're passing to the MPMoviePlayerController an URL pointing to a m3u8 file. That is a playlist. To play media with MPMoviePlayerController, you have to set it an actual video file. You should parse the playlist to get the link to the real video and then init your MPMoviePlayerController with the real link.
Check M3U - Wikipedia and MPMoviePlayerController reference
Also check this related question
EDIT: Thanks to Hugo Silva, I realized that MPMoviePlayerController is able to play live streams in m3u8 format, since I've not seen anything wrong in your code, I suggest you to check if it's a problem of your stream. Try using one of the samples provided by Apple. Also make sure that your stream meets Apple's requirements for HTTP Streaming
I am facing some problem in playing multiple videos on iPAD. I am trying to play multiple thumbnail videos on the same view. You can say its much like the CCTV camera.Well, i have no clue. Please help me. Thanks in advance...
MPMoviePlayerController will allow multiple instances, but only one of them can be playing their movie at any given time.
It mentions it here: http://developer.apple.com/library/ios/#documentation/mediaplayer/reference/MPMoviePlayerController_Class/MPMoviePlayerController/MPMoviePlayerController.html
From the article:
Note: Although you may create multiple MPMoviePlayerController objects and present their views in your interface, only one movie player at a time may play its movie.
You can't use the MKMediaFramework to play multiple videos. You can however do this with the lower level AVFoundation Framework. It's not as hard as you might think and I've made a tutorial that goes over it here: http://www.sdkboy.com/?p=66
Essentially what you need to do is extend UIView so it contains an AVPlayerLayer to which the output of an AVPlayer object is directed, then you can create multiple instances of this UIView that you feed video using AVPlayer instances.
This is actually pretty simple to do on the iPad.
You basically need multiple MPMoviePlayerController objects.
Each MPMoviePlayerController object has a view property, you just need to set the frames of the views on the different MPMoviePlayerController objects to match what you want it to look like.
Here is a simple example using two MPMoviePlayerController objects ans 2 different frames:
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL: myURL];
[[player view] setFrame: yourFrame1];
[myView addSubview: [player view]];
// ...
[player play];
MPMoviePlayerController *player2 =
[[MPMoviePlayerController alloc] initWithContentURL: myURL2];
[[player2 view] setFrame: yourFrame2];
[myView addSubview: [player2 view]];
// ...
[player2 play];
May be When Creating a WebView and using a HTML5 Video instance you can run multiple videos at the same time
I'm working with the MPMoviePlayerController for the iOS platform and am not sure why the "Done" and "Loading Movie..." controls are not displaying automatically when loading a new video.
My original implementation of this was to use the UIWebView control to stream the videos, and when the videos are accessed, the "Done" and "Loading Movie..." controls are displayed until the video is loaded and ready to play. I would like to reproduce the same user experience with the MPMoviePlayerController.
Should I get the "Done" and "Loading Movie..." control overlays for free? If not, what do I have to set to get them to show up while the video is loading?
NSURL *videoUrl = [NSURL URLWithString:urlString];
self.moviePlayer = [[[MPMoviePlayerController alloc] init] autorelease];
self.moviePlayer.movieControlMode = MPMovieControlModeDefault;
[self.moviePlayer setContentURL:videoUrl];
[self.moviePlayer prepareToPlay];
[self.view addSubview:self.moviePlayer.view];
[[self.moviePlayer view] setFrame: [self.view bounds]];
[self.moviePlayer setFullscreen:YES animated:YES];
This is answer to your follow-up question, but anyways... You can speed-up things a little bit with this:
prepareToPlay
Prepares the current item for playback. (required)
- (void)prepareToPlay
This method is called automatically when you call the play method. Calling it before you call play gives the receiver a chance to prepare items sooner and may result in decreased latency when starting playback. However, calling this method may also interrupt any active audio sessions.
Available in iOS 3.2 and later.
Declared In MPMediaPlayback.h
For some reason, the expand button the arrow points to in the screenshot below causes the view controller that initiated video playback to animate back over top of the video, but without stopping video playback which means you can still hear the audio even though the video is no longer visible. I've tried other movie control styles, but there are other problems with those (for example, no controls causes the player to play the entire video before dismissing, i.e. no 'Done' button).
Here is the code that initiates the video playback:
player = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
[player setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[[self navigationController] presentModalViewController:player animated:YES];
[[player moviePlayer] play];
Any ideas/suggestions as to how I can either disable that button or receive its notification so I can respond accordingly?
Thanks.
I can't find a solution to this, but I did find a workaround. I simply call [player stop]; in my -viewDidLoad of the calling view controller. The outcome won't be what the user expects when they press that button, but it's better than allowing the video to continue to play when they press it.
