I have recently started adding videos to ios apps using AVPlayer.But,now I have to get video data in chunks(HLS) rather than getting all data together ,but I am not able to understand the difference between this concept of playing data obtained in chunks or playing the whole data obtained altogether as implemented below .I have tried understanding this thing and looked for examples on internet but got the same thing as already implemented by me.Kindly give your suggestions and guidance that can help me to move forward.Thanks in advance!
-(void)playVideo:(NSURL*)videoURL
{
AVPlayerItem* playerItem = [AVPlayerItem playerItemWithURL:videoURL];
AVPlayer* playVideo = [[AVPlayer alloc] initWithPlayerItem:playerItem];
_playerViewController = [[AVPlayerViewController alloc] init];
_playerViewController.player = playVideo;
_playerViewController.view.frame = self.view.bounds;
[self.view addSubview:_playerViewController.view];
[playVideo play];
}
Read this Document from Apple.
When you init player, it doesn't mean that player is ready to play. You should observe player's status until you get AVPlayerStatusReadyToPlay status.
From your code, you init player and directly start playing video. You should observe status of player by following code.
[player addObserver:self forKeyPath:#"status" options:0 context:&PlayerStatusContext];
I'm developing a iPhone app and need to play the animation video in the background. This video should run until the user touch's the screen of the app. Not exactly the screensaver but this should happen for the first time when the app is opened.
How can play the video file in the background and screen buttons on top of the video in the app?
Add video player in your view of subview and your view must be a transparent layer makes.
your app delegate check the user coming first time or not.
NSString *path = [[NSBundle mainBundle] pathForResource:#"testVideo" ofType:#"mp4"];
MPMoviePlayerController *myPlayer = [[MPMoviePlayerController alloc] init];
myPlayer.shouldAutoplay = YES;
myPlayer.repeatMode = MPMovieRepeatModeOne;
myPlayer.fullscreen = YES;
myPlayer.movieSourceType = MPMovieSourceTypeFile;
myPlayer.scalingMode = MPMovieScalingModeAspectFit;
myPlayer.contentURL =[NSURL fileURLWithPath:path];
[self.view addSubview:myPlayer.view];
[myPlayer play];
Simply add MPMoviePlayerController as background and play the video,
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL: video_url];
[player prepareToPlay];
[player.view setFrame: requiredFrame];
[self.view addSubview: player.view];
After that, add tap gesture to whole view and remove player on tap gesture method..
I am trying to get a videostream to work.
My Code works super, it starts playing (fetches the Video From an url provided by Apple Support Sites - the player plays the first four seconds of the Video and then when this little status bar thing wants to automatically hide the player goes blackscreen (with Status bar I mean the indicator of Time, with the fullscreen Button etc.).
I cant Post sourcecode right now because I am writing with my iPhone, so I will do that later...
Hope That my description helps you to understand and maybe you can help me.
In my .h File:
MPMoviePlayerController *mp;
In my .m File:
NSURL *mediaURL = [NSURL URLWithString:#"http://km.support.apple.com/library/APPLE/APPLECARE_ALLGEOS/HT1211/sample_iTunes.mov"];
mp = [[MPMoviePlayerController alloc] init];
[mp setShouldAutoplay:YES];
[mp setMovieSourceType:MPMovieSourceTypeStreaming];
[mp setContentURL:mediaURL];
[mp setControlStyle:MPMovieControlStyleEmbedded];
[mp setFullscreen:NO];
[mp setScalingMode:MPMovieScalingModeNone];
[mp prepareToPlay];
mp.view.frame=CGRectMake(0, 0, 320, 220);
[self.view addSubview:mp.view];
this is working fine :)
I would like to open the iPad movie player from my app to play a video.
The video will already be on the device, and the app is destined to ad-hoc distribution on pre-configured device, thus we can say the video will always be here.
My problem is that I can't figure out how to open the video app! I've searched a lot of things, including UTI, or embedded video, but that doesn't meet my needs.
Is there any way to simply open the player with the specified file ?
Do you need to open the video app per se? Or do you just need to play local video file from your app? In the latter case, you can just use MPMoviePlayerController (or the wrapping MPMoviePlayerViewController for iOS > 3.2).
Something like this works for me.
NSURL * url = [[NSBundle mainBundle] URLForResource:#"yourvideo" withExtension:#"mov"];
player = [[MPMoviePlayerController alloc] initWithContentURL:url];
player.view.frame = self.view.bounds;
player.movieSourceType = MPMovieSourceTypeFile;
[self.view addSubview:player.view];
player.shouldAutoplay = NO;
player.fullscreen = YES;
[player prepareToPlay];
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>
