I'm trying to play a video in mp4 format from URL over HTTPS using MPMoviePlayerController, but video is not playing and I receive an error in logs:
_itemFailedToPlayToEnd: {
kind = 1;
new = 2;
old = 0;
}
Is any way to play this kind of video on iOS?
Here's my code:
#import "FirstViewController.h"
#import <MediaPlayer/MediaPlayer.h>
#interface FirstViewController ()
#property (nonatomic, strong) MPMoviePlayerController *moviePlayer;
#end
#implementation FirstViewController
- (void)viewDidLoad
{
[super viewDidLoad];
[self playBtnPressed];
}
-(void)playBtnPressed
{
NSURL *url=[[NSURL alloc] initWithString:#"https://....mp4"];
_moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:_moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackDonePressed:) name:MPMoviePlayerDidExitFullscreenNotification object:_moviePlayer];
_moviePlayer.controlStyle=MPMovieControlStyleDefault;
//moviePlayer.shouldAutoplay=NO;
[_moviePlayer play];
[self.view addSubview:_moviePlayer.view];
[_moviePlayer setFullscreen:YES animated:YES];
}
- (void) moviePlayBackDonePressed:(NSNotification*)notification
{
[_moviePlayer stop];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerDidExitFullscreenNotification object:_moviePlayer];
if ([_moviePlayer respondsToSelector:#selector(setFullscreen:animated:)])
{
[_moviePlayer.view removeFromSuperview];
}
_moviePlayer=nil;
}
- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
[_moviePlayer stop];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:_moviePlayer];
if ([_moviePlayer respondsToSelector:#selector(setFullscreen:animated:)])
{
[_moviePlayer.view removeFromSuperview];
}
}
#end
Probably video aspect ratio issue try setting aspect ratio
[player setScalingMode:MPMovieScalingModeAspectFit];
player.view.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
Or check if the video file is there in the specified URL location
It seems to be an iOS 7 issue.
Apparently, moviePlayer.movieSourceType = MPMovieSourceTypeStreaming; does not work anymore.
For me, replacing it with MPMovieSourceTypeFile solved this error.
Use following code it will work for you. Be sure that you have the notification observer declared before playing movie, as follows:
[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController.moviePlayer];
moviePlayerController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[moviePlayerController.moviePlayer prepareToPlay];
[self presentMoviePlayerViewControllerAnimated:moviePlayerController];
[moviePlayerController.moviePlayer play];

I'm using MPMoviePlayerViewController to play video. In my app I am playing video(s) that are in the app, using the standard MPMoviePlayerController class. It works fine on iOS 7 and 8
The first time around around this works great, however after watching 1 video if you try and watch something else the app crashes on MPMoviePlayerController's play method with the error:
: CGContextSaveGState: invalid context 0x0
: CGContextClipToRect: invalid context 0x0
: CGContextTranslateCTM: invalid context 0x0
: CGContextDrawShading: invalid context 0x0

You may well be getting the error because of notifications being sent to a removed controller object as #Bannings says. Nevertheless, I have a couple of other suggestions that will improve your code (and I am fairly sure will remove the error).
Firstly, the documentation says that you should register for the MPMoviePlayerLoadStateDidChangeNotification and use the loadState method to determine when the movie is ready to start playing. I strongly suggest that you do that.
Secondly, you are instantiating a MPMoviePlayerController every time your view appears. I would suggest that you create a single AFPlayerViewController and a single MPMoviePlayerController. Present the same AFPPlayerViewController whenever you wish to play another movie.
When you first instantiate the MPMoviePlayerController, you will need a a URL, for its init method, but subsequent movies can be started using the contentURL property of MPMoviePlayerController
A side advantage of my suggestion is that it will be very easy for a user to pause a movie, go to a different view, and then quickly resume when they return to the movie view.
Have you called the removeNotification if you try and watch something else? try to add viewDidDisappear:
- (void)viewDidDisappear:(BOOL)animated {
[super viewDidDisappear:animated];
[self removeNotification];
}
I think I see the real problem here: you should be using MPMoviePlayerController not MPMoviewPlayerViewController. Make that change, and see if the crash disappears. My suggestion about loadState should be followed too.
I am using MPMoviePlayerController for playing video files and I am able to apply the natural size of the video with the help of MPMovieNaturalSizeAvailableNotification. But after adding this notification seek bar is not appearing in the controlStyle (all other buttons are present). If I make the video frame hard coded (i.e. without considering the natural height) I will not get this issue.
Here is my code
// Declartion class level
MPMoviePlayerController *moviePlayer;
float naturalHeight;
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
moviewPlayer = [[MPMoviePlayerController alloc] initWithContentURL: movieURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(movieReadyForDisplay:)
name:MPMoviePlayerReadyForDisplayDidChangeNotification
object:moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(movieNaturalSizeAvailable:)
name:MPMovieNaturalSizeAvailableNotification
object:moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer];
[self.view addSubview:moviePlayer.view];
moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
moviePlayer.fullscreen = NO;
moviePlayer.scalingMode = MPMovieScalingModeFill;
moviePlayer.shouldAutoplay = NO;
//I am able to get the seek bar here if I set the static height . But I want natural height here.
// moviePlayer.frame = CGRectMake(0, 0, self.view.frame.size.width , naturalHeight);
}
-(void) movieNaturalSizeAvailable:(NSNotification *)notification{
MPMoviePlayerController *player = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMovieNaturalSizeAvailableNotification object:player];
naturalHeight = player.naturalSize.height;
if(naturalHeight > self.view.frame.size.height) {
naturalHeight = self.view.frame.size.height;
}
}
-(void) movieReadyForDisplay:(NSNotification *)notification{
MPMoviePlayerController *player = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerReadyForDisplayDidChangeNotification object:player];
NSLog(#">> %f ", naturalHeight); //OK here
[player view].frame = CGRectMake(0, 0, self.view.frame.size.width , naturalHeight);
player.view.center = self.view.center;
[player prepareToPlay];
[player play];
}
- (void)moviePlayBackDidFinish:(NSNotification*)notification {
MPMoviePlayerController *player = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:player];
[player stop];
[player.view removeFromSuperview];
}
#end
I believe this issue might be because the natural size calculations of
video player occur after it sets its components frames. If I don't use natural size, it works perfectly. How can I fix this issue?
try this
before starting the video
player.controlStyle = MPMovieControlStyleNone;
and when movie starts playing then set
player.controlStyle = MPMovieControlStyleFullscreen;
You can get play callback from MPMediaPlayback protocol.
Im using MPMoviePlayerController inside a class Ive built called MYVideo. Here is the code:
#import <MediaPlayer/MediaPlayer.h>
#import "MYVideo.h"
#interface MYVideo()
#property (strong, nonatomic) UIView * viewRef;
#property (strong, nonatomic) NSDictionary * contentData;
#property (strong, nonatomic) MPMoviePlayerController * videoController;
#end
#implementation MYVideo
#synthesize contentData,videoController,viewRef;
- (MYVideo*) initIntoView: (UIView*) view withContent:(NSDictionary*)contentDict{
self=[super init];
viewRef=view;
contentData = contentDict;
NSString *rawUrl = [[NSString alloc] initWithFormat:#"http://....com/app/%#.mp4", [contentDict objectForKey:#"cnid"]];
NSURL *videoUrl = [[NSURL alloc]initWithString:rawUrl];
videoController = [[MPMoviePlayerController alloc] initWithContentURL:videoUrl];
videoController.movieSourceType=MPMovieSourceTypeFile;
videoController.view.frame = viewRef.bounds;
[videoController.view setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight];
videoController.controlStyle=MPMovieControlStyleNone;
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playbackFinished:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:videoController];
[viewRef addSubview:videoController.view];
return self;
}
- (void) playbackFinished: (NSNotification*) notification {
NSLog(#"playback finished");
if(videoController){
[videoController play];
}
}
- (void) play: (int) offset {
videoController.initialPlaybackTime=offset;
[videoController play];
}
- (void) stop {
[[NSNotificationCenter defaultCenter] removeObserver:self
name:#"playbackFinished"
object:nil];
if(videoController){
[videoController stop];
}
}
- (void) destroy {
if(videoController){
[videoController stop];
[videoController.view removeFromSuperview];
}
}
#end
My problem is that occasionally I get the following error:
playback finished
-[__NSCFString playbackFinished:]: unrecognized selector sent to instance 0x1664e6a0
Which I'm guessing is caused by the MPMoviePlayerController firing off the "playbackFinished" notification when this video class has already been released. Am I right in thinking this?
Thing is, this MYVideo class should still be there while the video is playing, this error only occurs when the video is playing and in the console log my NSLogging of "playback finished" immeditately preceeds the crash. Also I never shut down the class without first removing the "playbackFinished" observer.
Can anybody suggest to me why I would be getting this crash?
Many thanks.
Yeah it looks like you are not removing the observer, as this code:
[[NSNotificationCenter defaultCenter] removeObserver:self
name:#"playbackFinished"
object:nil];
should be:
[[NSNotificationCenter defaultCenter] removeObserver:self
name:#"playbackFinished:"
object:nil]; // ^
or better still (as you don't really care what's being called):
[[NSNotificationCenter defaultCenter] removeObserver:self
name:nil
object:videoController];
Also given you use tests like if (videoController) { ... } in so many places, you need to ensure it goes nil ASAP:
- (void)destroy {
if(videoController){
[videoController stop];
[videoController.view removeFromSuperview];
videoController = nil; // Add
}
}
In MPMoviePlayerController, when ever the controls disappear, even the status bar is disappearing with it. Since i want the status bar to appear even when the control disappears, i placed the below code
[[UIApplication sharedApplication] setStatusBarHidden:NO];
But the above code is not making any difference, teh status bar is getting disappeared along with the player controls. How to solve this problem.
Please find the code below, and let me know how to rectify it.
- (void) readyPlayer {
mp = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
if ([mp respondsToSelector:#selector(loadState)])
{
// Set movie player layout
[mp setControlStyle:MPMovieControlStyleFullscreen];
[mp setFullscreen:YES];
// May help to reduce latency
[mp prepareToPlay];
// Register that the load state changed (movie is ready)
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerLoadStateChanged:) name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
} else {
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePreloadDidFinish:) name:MPMediaPlaybackIsPreparedToPlayDidChangeNotification
object:nil];
}
// Register to receive a notification when the movie has finished playing.
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
}
- (void) moviePlayerLoadStateChanged:(NSNotification*)notification {
NSLog(#"moviePlayerLoadStateChanged");
// Unless state is unknown, start playback
if ([mp loadState] != MPMovieLoadStateUnknown)
{
// Remove observer
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerLoadStateDidChangeNotification
object:nil];
[[UIApplication sharedApplication] setStatusBarHidden:NO];
// Rotate the view for landscape playback
[[self view] setBounds:CGRectMake(0, 0, 768, 1000)];
// Set frame of movieplayer
[[mp view] setFrame:CGRectMake(0, 0, 768, 1000)];
// Add movie player as subview
[[self view] addSubview:[mp view]];
// Play the movie
[mp play];
}
}
- (void) moviePreloadDidFinish:(NSNotification*)notification {
// Remove observer
NSLog(#"moviePreloadDidFinish");
[[NSNotificationCenter defaultCenter] removeObserver:nil
name:MPMediaPlaybackIsPreparedToPlayDidChangeNotification
object:nil];
[[UIApplication sharedApplication] setStatusBarHidden:NO];
// Play the movie
[mp play];
}
- (void) moviePlayBackDidFinish:(NSNotification*)notification {
NSLog(#"moviePlayBackDidFinish");
[[UIApplication sharedApplication] setStatusBarHidden:NO];
// Remove observer
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
[self dismissModalViewControllerAnimated:YES];
}
This is a well-known issue of MPMovieControlStyleFullscreen. Simply use the MPMovieControlStyleEmbedded controlStyle and you are good to go.
And, by the way, that is the more adequate controlStyle for embedded usage anyways.
I am writing a simple method to start a streaming video full-screen and letting the user quit pressing the "Done" button. Problem is, I can't remove the MPMediaPlayerController view, or perhaps I am doing it the wrong way.
- (IBAction)playVideoButtonPressed:(id)sender {
NSURL *url = [NSURL URLWithString:#"http://mysite.com/video.mov"];
mp = [[MPMoviePlayerController alloc] initWithContentURL: url];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayerPlaybackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
if ([mp respondsToSelector:#selector(setFullscreen:animated:)]) {
mp.controlStyle = MPMovieControlStyleFullscreen;
mp.shouldAutoplay = YES;
[self.view addSubview:mp.view];
[mp.view setTag:3];
[mp setFullscreen:YES animated:YES];
}
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:mp];
[mp play];
}
- (void)moviePlayBackDidFinish:(id)sender {
NSLog(#"Quitting MoviePlayer");
[mp.view removeFromSuperview];
}
The idea is that the MPMediaPlayerController view is called clicking on a button in the app, and it is dismissed by clicking the "Done" video or when the video ends.
I should have used MPMoviePlayerViewController.
