Say we are downloading a large video - its 50Mb - but only 25Mb has downloaded so far - is it possible to start playing the video before its completely downloaded?
I am going to assume you are using MPMoviePlayerController for your video...
MPMoviePlayerController has a loadState property that you can monitor with this notification. Check to see if the video has been downloaded to a playable extent and then play.
//Begin observing the moviePlayer's load state.
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerLoadStateChanged:) name:MPMoviePlayerLoadStateDidChangeNotification object:moviePlayer];
- (void)moviePlayerLoadStateChanged:(NSNotification *)notification{
//NSLog(#"State changed to: %d\n", moviePlayer.loadState);
if(moviePlayer.loadState == MPMovieLoadStatePlayable && [videoIndicator isAnimating]){
//if load state is ready to play
[videoIndicator stopAnimating];//Pause and hide the indicator
[self.contentView addSubview:[moviePlayer view]];
[moviePlayer setFullscreen:YES animated:YES];
[moviePlayer play];//play the video
}
}
And this is very important: If you are trying to download a video more than 10 ten minutes long, you will need to use HTTP Live Streaming.

I want to play a video in seprate view controller, where I can Play/Pause or dismiss that view controller. In my case, I recorded the video in my app and calling this delegate method in order to save this video in assets, but I want to play it first before using the ALAssetsLibrary.
- (void)captureOutput:(AVCaptureFileOutput *)captureOutput
didFinishRecordingToOutputFileAtURL:(NSURL *)outputFileURL
fromConnections:(NSArray *)connections
error:(NSError *)error
And the TEMO URL im getting is :
file:///private/var/mobile/Containers/Data/Application/EA6D31AC-6CC3-4BDF-B874-BC6F30BA5677/tmp/output.mov
How can I play this video in next view controller or in same view controller??
My try:
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:outputFileURL];
player.view.frame = CGRectMake(184, 200, 400, 300);
[self.view addSubview:player.view];
[player play];
PS: This is showing a black screen area but not actually playing this video.
I had the same problem a few days ago. It ends up that I was calling play method to soon, before the video become ready to play. So, add this before call [player play]. This will notify whenever your video become read to play in MPMoviePlayerController.
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(videoPlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:player];
Then setup the observer:
- (void)videoPlayBackDidFinish:(NSNotification *)notification {
[[NSNotificationCenter defaultCenter]removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
}
This worked for me.
Hope it helps.
I am using MPMoviePlayer to play video in my iPhone application.
I want play video in loop means wants to play single video repeatedly.
I am using following code to repeat the video:
MoviePlayer.repeatMode = MPMovieRepeatModeOne;
It is working properly on Simulator and higher phone But it is not working properly on iPhone 4.
It is not repeating the video on iPhone 4 Device
Is there any specific reason for that? is there any solution for that?
My iPhone is iPhone 4 with updated iOS 7
Thank you
This Solution I have implemented:
I have used MPMoviePlayerPlaybackStateDidChangeNotification this Notification
Added following notification to Movie Player
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackDidFinishedFromSetUnderway:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:MoviePlayer];
Notification Method:
-(void)moviePlayBackDidFinishedFromSetUnderway:(NSNotification *)dict{
if (dict.object == MoviePlayer) {
NSInteger reason = [[dict.userInfo objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] integerValue];
if (reason == MPMovieFinishReasonPlaybackEnded)
{
[MoviePlayer prepareToPlay];
[MoviePlayer play];
}
}
}
Done !!! It is working properly now ... :)
I am using the MPMoviePlayerController to play some streaming videos of type .m3u from a url. They video player launches perfectly and the video starts playing perfectly as well, but as soon as I press the Seek Forward or Next or beginSeekingForward button the video complete stops/freezes. After that I can click Done to dismiss the player or scrub the progress bar and it will come back to play to video. But the I can't click on the play/pause or at least seems not to do anything.
I have spent quite sometime looking around online for answer or at least a hint so I can tackle this issue in the right direction but not luck. So, I really hope someone could help with this. Btw, this only happens on iOS 8+, currently I am testing it in iOS 8.1.
This is how I create the player and load the video to it.
NSURL *videoURL = [NSURL URLWithString:self.video.flvurl];
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: videoURL];
self.moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
self.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
self.moviePlayer.shouldAutoplay = NO;
self.moviePlayer.fullscreen = YES;
self.moviePlayer.repeatMode = YES;
self.moviePlayer.view.backgroundColor = [UIColor blackColor];
self.moviePlayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.moviePlayer.view.frame = self.containerView.frame;
[self.view addSubview:self.moviePlayer.view];
[self.moviePlayer prepareToPlay];
[self.moviePlayer play];
I have tried using multiple different notifications to see if I can catch this within one of them, but not luck at all. I have tested all of these notifications so far.. I have added this to the self.moviePlayer and also the self.moviePlayer.view not luck in either of them.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(willResignActive:)
name:UIApplicationWillResignActiveNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self

name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoStartedPlaying:)
name:MPMoviePlayerNowPlayingMovieDidChangeNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self

object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self

[[NSNotificationCenter defaultCenter] addObserver:self

object:self.moviePlayer.view];
Well, if you need more relevant code please let me know. I really need some help with this.. Thanks in advance.
This code worked for me, but just to get rid of freezing. Sign up for the MPMoviePlayerLoadStateDidChangeNotification, like you did above. In the callback method, I simply set the movie players contentURL to the original URL I had initialized it with at the start, and set the movie player to play again.
The functionality of this is when you tap the NEXT or BACK buttons in fullscreen, the video simply starts playing again from the start. That may not be ideal since the user might not expect this, but at least it will stop it from freezing. I'm currently trying to find a better workaround.
- (void) videoLoadState:(NSNotification *)notification
{
MPMovieLoadState loadState = moviePlayer.loadState;
if(loadState == MPMovieLoadStateUnknown)
{
NSLog(#"Movie Load state is unknown");
moviePlayer.contentURL = currentlyPlayingVideoURL;
[moviePlayer prepareToPlay];
}
}
If you check the value of MPMoviePlaybackState in this method, it will always be MPMoviePlaybackStateStopped when NEXT or BACK are pressed, so I'm not sure how to handle it...
i am using UIWebView to play embed video from youtube, and my problem is how can i call a method when the embed video starts to play?
i found the solution myself so if anyone want it here it is:
in - (void)viewDidLoad add:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(videoStrated:) name:#"UIMoviePlayerControllerDidEnterFullscreenNotification" object:nil];
and add:
-(void)videoStrated:(NSNotification *)notification
{
NSLog(#"video started");
}
in implemention file
In my application i play video using mpmovieplayercontroller
first set scaling mode to MPmovieScalingmodefill and display video correct to scalingmode.
then after i view video in full screen and exit full screen then not set scaling mode to
MPmovieScalingmodeFill and display video in defualt mode.
below my code for video playing
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(ExitFullScreen:)
name:MPMoviePlayerWillExitFullscreenNotification object:nil];
[appDelegate.moviePlayerController setContentURL:fileURL];
if ([appDelegate checkDevice])
{
[appDelegate.moviePlayerController.view setFrame:CGRectMake(0,0, 320,463)];
}
else
{
[appDelegate.moviePlayerController.view setFrame:CGRectMake(0,0, 320,375)];
}
[appDelegate.moviePlayerController prepareToPlay];
appDelegate.moviePlayerController.scalingMode=MPMovieScalingModeFill;
appDelegate.moviePlayerController.controlStyle=MPMovieControlStyleDefault;
appDelegate.moviePlayerController.shouldAutoplay=NO;
[appDelegate.moviePlayerController setFullscreen:YES animated:YES];
[appDelegate.moviePlayerController play];
[self.view addSubview:appDelegate.moviePlayerController.view];
- (void)ExitFullScreen:(NSNotification *)notification{
NSLog(#"Exit full Screen");
[appDelegate.moviePlayerController setControlStyle:MPMovieControlStyleEmbedded];
[appDelegate.moviePlayerController setScalingMode:MPMovieScalingModeFill];}
so my probleem is how can set scaling mode after exit full screen or do not change scaling mode after exit screen ?
please help me out.
thanks.
This isn't the "ideal" solution, but it works!
Basically, once you exit full screen the MPMoviePlayerController instance gets all screwed up and resetting the scaling property to MPMovieScalingModeFill won't help no matter where or when you do it (I've tried all sorts of stuff and after an hour gave up). Easiest solution is to remove the MPMoviePlayerController and simply allocate a new instance of MPMoviePlayerController each time full screen is exited (not ideal, but totally works):
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:NO];
if (self.moviePlayer != nil)
[self.moviePlayer.view removeFromSuperview];
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:self.videoURL];
self.moviePlayer.view.frame = CGRectMake(#, #, #, #);
self.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
self.moviePlayer.shouldAutoplay = NO;
[self.moviePlayer setContentURL:self.videoURL];
[self.moviePlayer prepareToPlay];
[self.moviePlayer setScalingMode:MPMovieScalingModeFill];
[self.view addSubview:self.moviePlayer.view];
}
PS: Don't forget to call super's viewDidAppear or suffer all sorts of unforeseeable mayhem (a very common mistake in iOS development)
I believe this will generate the MPMoviePlayerScalingModeDidChangeNotification.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(movieScalingModeDidChange:)
name:MPMoviePlayerScalingModeDidChangeNotification
object:nil];
MPMoviePlayerScalingModeDidChangeNotification
Posted when the scaling mode of a movie player has changed. There is no userInfo dictionary. Scaling mode can change programmatically or by user interaction. To set or retrieve the scaling mode of a movie player, access its scalingMode property. The movie player whose state has changed is available as the object associated with the notification.
