I am trying to play video inside a view so I can move it around, perform layout together with other views, but I can't seem to get it work to using MPMoviePlayerController. I came across this link on how to play video in portrait mode but this is not possible because the video source is coming from the web and should be playable in different platforms not only on iPhone.
I've been successful rotating the video and scaling it but it is still contained in a UIWindow which fills the whole screen. Is there a way to create an intermediate UIWindow but not visible in the current screen, so you can play the video there and probably add subviews and return everything as a UIView where I can place it anywhere? Similar to creating a CGGraphics context draw objects there and output as an image. This would also prevent the current screen from rotating from portrait to landscape.

IN response to Jasarien's answer (below), actually it is possible to rotate and scale a video. After the video has preloaded it creates another instance of UIWindow which then becomes the keywindow at that moment. By creating a callback selector at MPMoviePlayerContentPreloadDidFinishNotification, it is possible to apply transform modification of the current keywindow.
-(void)myMovieFinishedPreloading:(NSNotification*)aNotification {
NSArray *windows = [[UIApplication sharedApplication] windows];
UIWindow *moviePlayerWindow = nil;
if ([windows count] > 1)
{
moviePlayerWindow = [[UIApplication sharedApplication] keyWindow];
}
CGAffineTransform transform = CGAffineTransformMakeScale(0.5, 0.5);
transform = CGAffineTransformRotate(transform, -90.0f*M_PI/180.0f);
[moviePlayerWindow setTransform:transform];
}
Now my question is now that its part of UIWindow and since UIWindow is a UIView subclass, is it possible to subview this UIView? Also I can't seem to disable the autorotate behavior upon preloading of the video.
Video on the iPhone is played fullscreen at all times. The iPad with iOS 3.2 has APIs that allow a video to be treated as a normal view.
For the iPhone, without writing your own video view you're not going to be able to get the functionality you want.
Check out AVPlayer and AVPlayerLayer.

I have an iPhone app where I load an UIImagePickerController onto a UIViewController. I then have a custom view on top of the camera. Now when the user takes a photo it is loaded onto a UIImageView which presents it to the user asking if you want to use that photo or take another (removing the image from the UIImageView). This works perfectly.
Now If the user has just recorded a video I wanted to take a snapshot preview somewhere in the video and present it as a static image in the same UIImageView. I do this with the following code:
MPMoviePlayerController *videoPlayer = [[MPMoviePlayerController alloc] init];
videoPlayer.shouldAutoplay = NO;
[videoPlayer setContentURL:[info valueForKey:UIImagePickerControllerMediaURL]];
UIImage *videoScreenShot = [videoPlayer thumbnailImageAtTime:(videoPlayer.duration/2.0) timeOption:MPMovieTimeOptionNearestKeyFrame];
photoPreview.image = videoScreenShot;
[videoPlayer release]
This works as intended. The problem is if I want to take another video. When I call:
[videoPlayer setContentURL:[info valueForKey:UIImagePickerControllerMediaURL]];
The camera shutter closes and the camera is seemingly dismissed. Trying to take a picture or recording video gives me:
UIImagePickerController: ignoring request to take picture; camera is not yet ready.
UIImagePickerController: ignoring request to start video capture; camera is not yet ready.
I've tried calling the following after, which has no effect:
myImagePicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType: UIImagePickerControllerSourceTypeCamera];
[myImagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
I tried adding the UIImagePickerController to the UIIViewController again, which caused some fantastic freeze-ups.
Finally I tried commenting out the UIViewController's [super didReceivedMemoryWarning] line of didReceivedMemoryWarning. Which also had no effect.
I'm guessing MPMoviePlayerController takes over something UIImagePicker also needs. How do I give it back?
I would suggest setting your MPMoviePlayerController to nil before showing the UIImagePickerController, or maybe taking its view out of the interface temporarily. Both of these contain a movie player view, but there can be only one movie player view at a time in your application's interface. Thus they can interfere with each other, and that might be what's happening to you.
i have some mp4 files which are to be played in my iPad app.. I am able to do that quite well. right now i have a play button on blank black space in my app and the video plays after i tap the play button. The user will only come to know the content of the video after playing it.. But, i want the user to know about the video before playing itself . instead of the default black screen i want to show the video starting screen to make the video more interesting. To put it in simple words, i want my video space to be similar to youtube... IS there any way i which this can be done?? Thanks
Subclass MPMoviePlayerController (or however you're playing your video.. if you already use a custom class just add the code in there) and in viewDidAppear initialise a UIImageView with frame size equal to self.view.bounds using whatever background image you want for the loading screen. Add the UIImageView as a subview of self.view and call sendSubviewToBack: on it. When the player is ready to play, it will start drawing video frames on top of your subview, and you should not see it again.
- (void)viewDidAppear
{
UIImageView *loadingImage = [[UIImageView alloc] initWithImage:myImage];
[loadingImage setFrame:self.view.bounds];
[self.view addSubview:loadingImage];
[self.view sendSubviewToBack:loadingImage];
[super viewDidAppear];
}
This is a follow-on from: Overlay on top of Streaming MPMoviePlayerController
I've seen the various threads about checking for a new Window and then using that to apply my custom views to my fullscreen video however in SDK 4.1 this doesnt appear to be the case.
I have tried a timer and listening for UIWindowDidBecomeKeyNotification but in neither case does [[UIApplication sharedApplication] windows] ever contain more than 1 item.
I have tried adding my view to the players view property which works fine when displayed in place, but not when fullscreen, even if I add it in moviePlayBackDidEnterFullScreen event
I found a solution to this problem a few weeks ago:
It seems this method does not work on the iPad (I havent checked iPhone SDK 4>) so in order to get round it you can do the following.
After adding your video and setting to fullscreen you can add your controls directly to the UIWindow (e.g. [[[[UIApplication sharedApplication] windows] objectAtIndex:0] addSubView:myView]), they will then appear on top of your video video.
The only problem I have found with this is that they don't obey the orientation rules of the view and I have manually had to program the rotation code in the willRotateToInterfaceOrientation method of the view.
I have been fighting some code for about a week, and am hoping that someone else may have experienced this problem and can point me in the right direction.
I am using the MPMoviePlayerViewController to play a video on the iPad. The primary problem is that it works FLAWLESSLY on the iPad Simulator, but will not play at all on the iPad. I have tried re-encoding the video to make sure that isn't an issue. The video I'm using is currently a 480x360 video encoded with H.264 Basline 3.0 with AAC/LC audio. The video plays fine on the iPhone, and also does play through Safari on the iPad. The video actually loads, and you can scrub through the video with the scrubber bar and see that it is there. The frames actually display, but just will not play. If you click play, it just immediately stops. Even when I have mp.moviePlayer.shouldAutoplay=YES set, you can see the player attempt to play, but only for a split second (maybe 1 frame?).
I have tried just adding view with the following code:
in .h
------
MPMoviePlayerViewController *vidViewController;
#property (readwrite, retain) MPMoviePlayerViewController *vidViewController;
in .m
------
MPMoviePlayerViewController *mp=[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:videoURL]];
[mp shouldAutorotateToInterfaceOrientation:YES];
mp.moviePlayer.scalingMode=MPMovieScalingModeAspectFit;
mp.moviePlayer.shouldAutoplay=YES;
mp.moviePlayer.controlStyle=MPMovieControlStyleFullscreen;
[videoURL release];
self.vidViewController = mp;
[mp release];
[self.view addSubview:vidViewController.view];
float w = self.view.frame.size.width;
float h = w * 0.75;
self.vidViewController.view.frame = CGRectMake(0, 0, w, h);
I have also just tried to do a:
[self presentMoviePlayerViewControllerAnimated:self.vidViewController];
which I actually can not get to orient properly...always shows up in Portrait and almost completely off the screen on the bottom, and the app is only intended to run in either of the Landscape views...
If anybody needs more info, just let me know. I'm about at my wits end on this. ANY help will be GREATLY appreciated.
I see 2 problems here.
First you are not setting the frame of the view. Try adding
mp.view.frame = self.view.frame;
This is what fixed it for me.
Next the shouldAutorotateToInterfaceOrientation does not need to be called. This method simply tells you if the view supports an orientation. Check the Apple docs.
You may want to try shutting down the iPad (powering off), remove and re-install the app.
Just add a line after you add the movie player to the view:
[self.vidViewController.moviePlayer play];
See if it helps.
Thanks,

I am new to iphone development.I have created a application which able to play a video from a url.Is there any animation can be set for opening of the video player in iphone?.The video is opened normally in landscape view. I want to show the opening of video player with some animation.Is there any way out?
NSURL *movieURL = [NSURL URLWithString:#"http://url of movie"];
if (movieURL)
{
if ([movieURL scheme])
{
MovietryAppDelegate *appDelegate = (MovietryAppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate initAndPlayMovie:movieURL];
}
}
In the delegate class i have defined the initAndPlayMovie method.I used the Apple sample "movie player " for my reference.Thanks.
I guess you can create an UIImageView, and place a screenshot of the movie player on it. Then you can do some fancy effects by scaling the image view or changing its opacity. It may look like "opening".
After the movie is loaded, you will receive, MPMoviePlayerContentPreloadDidFinishNotification and now you can remove the image view.
