I'm new in iPhone Application Development, and now i faced a problem, can any one tell me how can i play a video randomly without pressing the play button. The video should start automatically while the application launch and play randomly without stopping. I don't have any idea how to do this. I don't have any code also. Please help me any one...
Thanks in advanced.
You could implement it like this:
You need a movie player configured with e.g. a file url and add it to your view
NSURL *url = [[NSBundle mainBundle] URLForResource:movieName withExtension:#"mov"];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
moviePlayer.view.frame = // set the frame
[self.view addSubview:moviePlayer.view];
Start the movie player
[moviePlayer play];
Listen to the notification
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(handleMoviePlayerStatChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:moviePlayer];
Start the video again
- (void)handleMoviePlayerStatChange:(NSNotification *)note {
NSLog(#"mp playback state %i", moviePlayer.playbackState);
if (moviePlayer.playbackState == MPMoviePlaybackStatePaused) {
[moviePlayer play];
}
}
To hide the video controls set the controlStyle property of the movie player instance:
moviePlayer.controlStyle = MPMovieControlStyleNone;
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!
This is probably because I am having a brain freeze but I don't believe I have come across MPVideoView before.
So I have a UIWebview with a HTML5 demo in it, this then plays a video (in the web view) which seems to create a new view of type MPVideoView. IS this a private class for Apple to use to show HTML5 Video content?
Does it have any delegate methods? So I could auto play it?
Can I move the controls about, I am guessing they are a subview of that view?
You can use MPMoviePlayerController for playing HTML5 video(considering you have the link to the video)
Use the following code
moviePlayer1 = [[MPMoviePlayerController alloc]
initWithContentURL:videoURL];
moviePlayer1.view.frame = CGRectMake(0, 0, 200, 110);
[self.view addSubview:moviePlayer1.view];
[[NSNotificationCenter defaultCenter]addObserver:self
selector:#selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayer1];
[moviePlayer1 play];
Delegate methods can be found here
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").
