Can't get movie to finish within loop - ios

I want a movie to play as often as there are objects in an array, but I want to make sure that the movie has finished playing each time.
Here's some -simplified- code that I'd expect to do just that:
- (void)loopThroughArray {
[Array enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
NSLog (#"Index = %i", idx);
moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[moviePlayerController play];
}];
}];
}
- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
moviePlayerController = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
NSLog(#"Movie playback finished");
}
Unfortunately, the code just runs through the loop, after which is plays the movie, as seen in the logs:
Index = 0
Index = 1
Index = 2
Index = 3
Index = 4
Index = 5
Movie playback finished
What am I doing wrong?
Thanks for your insights

MPMoviePlayerViewController Dismiss Without playing

The problem video can be seen in :
http://app.bowerchat.com/images/118_1435046739658.mp4
MPMoviePlayerViewController Dismissing immediately without play.
What can be reason?Some videos are loaded nicely and playing.
How can i check the video can be played or not?
I tried
NSLog(#"%lu",(unsigned long)self.mpController.moviePlayer.loadState);
NSLog(#"%d",self.mpController.moviePlayer == nil);
Results always 0 - 0
MY Code to play video
self.mpController = [[MPMoviePlayerViewController alloc] initWithContentURL:moveUrl];
[self.mpController.moviePlayer prepareToPlay];
NSLog(#"%lu",(unsigned long)self.mpController.moviePlayer.loadState);
NSLog(#"%d",self.mpController.moviePlayer == nil);
[parent presentMoviePlayerViewControllerAnimated:self.mpController];
The reason could be that movie that has extention *.mp4 is actually of different type.
Also try to add the following:
self.mpController.moviePlayer.shouldAutoplay = YES;
[self.mpController.moviePlayer play];
Try this snippet :
-(void)setupMovie
{
NSURL *movieURL = [NSURL fileURLWithPath:movieURL];
self.mpController = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
self. mpController.scalingMode = MPMovieScalingModeAspectFill;
self. mpController.controlStyle = MPMovieControlStyleNone;
self.mpController.view.frame = self.view.frame;
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerPlaybackStateDidChange:) name:MPMediaPlaybackIsPreparedToPlayDidChangeNotification object:nil];
[self.view addSubview:self.mpController.view];
[self.mpController prepareToPlay];
}
- (void)moviePlayBackDidFinish:(MPMoviePlayerController *)player
{
[self.mpController.view removeFromSuperview];
}
- (void)moviePlayerPlaybackStateDidChange:(NSNotification*)notification
{
if (self. mpController.isPreparedToPlay) {
[self. mpController play];
}
}
And make sure movieURL is correct and video exist by this provided url

Play video from url in objective c with buffering

Hi everyone I am working on an application in which I have a url of video and I have to play a video from that url. I have done this job from this code
- (IBAction)btnPlayVideo:(id)sender
{
NSString *fileName = #"Server Address/Vdieo.flv";
NSURL *streamURL = [NSURL URLWithString:fileName];
mPlayerVC = [[MPMoviePlayerViewController alloc] initWithContentURL:streamURL];
[self.view addSubview:mPlayerVC.view];
//play movie
MPMoviePlayerController *player = [mPlayerVC moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(willEnterFullscreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(playbackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
player.view.frame = self.view.frame;
[player setFullscreen:YES animated:YES];
[self.view addSubview:player.view];
[player prepareToPlay];
[player play];
}
//============Other Methods====================

My problem is that when this code run video player open and start loading and it takes too much time to run a video. Can anybody guide me how to run video in fast way from internet?
There's nothing in the code that suggests that lag is anything other than the time it takes to make the request and sufficiently buffer. The most common technique to improve UE is to start loading as early as possible, even before the user requests playback.
If this is possible, the code should be reorganized as follows:
// hang on to the movie player
#property(nonatomic,retain) MPMoviePlayerController *mp;
// call this as soon as its possible to know the user might want to see the video
- (void)primeVideo {
NSString *fileName = #"Server Address/Vdieo.flv";
NSURL *streamURL = [NSURL URLWithString:fileName];
MPMoviePlayerController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:streamURL];
// do this also in dealloc
[[NSNotificationCenter defaultCenter] removeObserver:self];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(willEnterFullscreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(playbackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
mp.shouldAutoplay = NO;
[mp prepareToPlay];
self.mp = mp;
}
That does as much prep as possible without changing the UI. The rest of your code from the button action is left, tweaked a little...
- (IBAction)btnPlayVideo:(id)sender {
// if there's any way that the user can request playback before
// you've called primeVideo, check for that here. But hopefully you
// can call primeVideo before user even sees the play button
if (!self.mp) [self primeVideo];
self.mp.view.frame = self.view.frame;
[self.mp setFullscreen:YES animated:YES];
[self.view addSubview:self.mp.view];
MPMovieLoadState state = [self.mp loadState];
if (state & MPMovieLoadStatePlaythroughOK) [self.mp play];
else self.mp.shouldAutoplay = YES;
}

NSNotificationCenter notification fired twice on swipe

I am building an app with AVPlayer that will play songs from an api.
When a song ends, next song will be played. For this I am using the following code:
- (void)viewDidLoad
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playbackFinished:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[_audioPlayer currentItem]];
}
-(void)playbackFinished:(NSNotification *)notification {
// flagSkip = NO;
NSLog(#"## %# ", NSStringFromSelector(_cmd));
// if(flagSkip == NO)
[[DataSingleton sharedMySingleton] nextTrack];
// else
// flagSkip = NO;
}
On Swipe gesture, next song will be played.
For this, am removing the notification observer and adding it again as follows:
- (IBAction)skipButtonPressed:(id)sender
{
[[DataSingleton sharedMySingleton] nextTrack];
[[NSNotificationCenter defaultCenter] removeObserver:self name:AVPlayerItemDidPlayToEndTimeNotification object:[_audioPlayer currentItem]];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playbackFinished:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[_audioPlayer currentItem]];
}else{
//
}
}
But when I swipe, sometimes the notification method gets called.
Where am I getting wrong? How do I solve this?
Edit to include [[DataSingleton sharedMySingleton] nextTrack]
-(void)nextTrack{
NSDictionary *prevTrackInfo;
if (currentIndex == -1){
// We're at the start of a refilled list, so previousTrack should be
// the only thing in the cache dir. Clean it up.
dispatch_queue_t removeFilesQueue;
NSLog(#"## %# removeFilesQueue", NSStringFromSelector(_cmd));
removeFilesQueue = dispatch_queue_create("com.zombieprocess.removeFilesQueue", DISPATCH_QUEUE_SERIAL);
dispatch_sync(removeFilesQueue, ^{
// Code goes here
NSError *error = nil;
[fileMgr removeItemAtPath:[self getFeedBandsCacheDir] error:&error];
[fileMgr createDirectoryAtPath:[self getFeedBandsCacheDir] withIntermediateDirectories:YES attributes:nil error:nil];
});
//dispatch_release(removeFilesQueue);
} else{
if (trackInfo){
prevTrackInfo = trackInfo;
}else{
NSLog(#"nextTrack, attempting to store prevTrackInfo, no trackInfo for currentIndex: %d", currentIndex);
}
}
currentIndex += 1;
// We should not have this, but just in case
if (currentIndex >= self.feedEntries.count) {
// We are at the end. Get the feed again.
NSLog(#"## %# currentIndex >= self.feedEntries.count", NSStringFromSelector(_cmd));
if (self.feedEntries.count == 0) {
[self loadFeed];
return;
}
currentIndex = 0; // This will loop it back to the beginning
// [self loadFeed];
// return;
}
trackInfo = [self.feedEntries objectAtIndex:currentIndex];
[self dispatchPlayNotification];
if (prevTrackInfo && [self isTrackCached:prevTrackInfo] && prevTrackInfo != trackInfo && feedEntries.count > [self numberOfSongsToCache]){
NSLog(#"nextTrack, deleting cached copy: %#", [[prevTrackInfo objectForKey:#"file_url"] lastPathComponent]);
[self deleteCachedTrack:prevTrackInfo completionBlock:^{
[self fillDownloadQueue];
}];
} else {
[self fillDownloadQueue];
}
}
I guess you've already switched the next song. So you can't remove notification observer with [_audioPlayer currentItem], because it is already changed.
Update 1.
Try to replace 1st and 2nd lines:
[[NSNotificationCenter defaultCenter] removeObserver:self name:AVPlayerItemDidPlayToEndTimeNotification object:[_audioPlayer currentItem]];
[[DataSingleton sharedMySingleton] nextTrack];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(playbackFinished:) name:AVPlayerItemDidPlayToEndTimeNotification object:[_audioPlayer currentItem]];
Instead of removing the notification listener, I would read the current state on the player inside the method (void)playbackFinished:(NSNotification *)notification.
For example:
- (IBAction)skipButtonPressed:(id)sender
{
didSkipSong = YES;
[[DataSingleton sharedMySingleton] nextTrack];
}
And in -(void)playbackFinished:(NSNotification *)notification
-(void)playbackFinished:(NSNotification *)notification {
if(didSkipSong){
didSkipSong = NO;
return;
}
[[DataSingleton sharedMySingleton] nextTrack];
}

MPMoviePlayerViewController Subview

I have a view within my view controller and have it declared as a property _movieSubview. I add a MPMoviePlayerViewController to _movieSubview and the video plays nicely.
-(void)moviePlay{
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:#"High Rope" ofType:#"mov"]];
_playerController=[[MPMoviePlayerViewController alloc]initWithContentURL:url];
//[self presentMoviePlayerViewControllerAnimated:_playerController];
_playerController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[_playerController.moviePlayer prepareToPlay];
_playerController.moviePlayer.repeatMode = MPMovieRepeatModeOne;
_playerController.moviePlayer.controlStyle = MPMovieControlStyleNone;
_playerController.moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
[_playerController.moviePlayer play];
/*[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayerDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:_playerController];*/
//---play partial screen---
_playerController.view.frame = CGRectMake(0, 0, 320, 460);
[_movieSubview addSubview:_playerController.view];
}
- (void)moviePlayerDidFinish:(NSNotification *)note
{
if (note.object == _playerController) {
NSInteger reason = [[note.userInfo objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] integerValue];
if (reason == MPMovieFinishReasonPlaybackEnded)
{
[_playerController.moviePlayer play];
}
}
}
My 2 questions are:
My status bar disappears when I add the MPMoviePlayerViewController inside my subview. How do I keep the status bar?
How can I have the video play twice on repeat, then wait for user to play after that?
You should present _playerController instead of adding as subview. Use this code while creating the instance of MPMoviePlayer:
[moviePlayer setFullscreen:YES animated:YES];
moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter];
[notificationCenter addObserver:self selector:#selector(moviePlayerEvent:) name:MPMoviePlayerLoadStateDidChangeNotification object:moviePlayer];
[notificationCenter addObserver:self selector:#selector(playBackStateChanged:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:moviePlayer];
-(void)moviePlayerEvent:(NSNotification*)aNotification{
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:NO];
}
-(void)playBackStateChanged:(id)sender{
MPMoviePlaybackState playbackState = [moviePlayerViewController.moviePlayer playbackState];
switch (playbackState) {
case MPMoviePlaybackStateStopped :
//play again
NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter];
[notificationCenter removeObserver:self];
break;
case MPMoviePlaybackStatePlaying :
break;
case MPMoviePlaybackStateInterrupted :
break;
}
}

AVQueuePlayer AVPlayerItemDidPlayToEndTimeNotification fails to call

Im using AVQueuePlayer to loop through an array of AVPlayerItems.
The way I'm looping it, I listen to the AVPlayerItemDidPlayToEndTimeNotification and every time its called, I add the current object to the end of the queue.
heres the code:
viewWillAppear
{
...
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[_queuePlayer currentItem]];
[_queuePlayer play];
}
- (void)playerItemDidReachEnd:(NSNotification *)notification {
AVPlayerItem *p = [notification object];
AVPlayerItem *fakeNew = [[AVPlayerItem alloc] initWithAsset:p.asset];
if (_queuePlayer.items.count == 1)
{
[p seekToTime:kCMTimeZero];
[_queuePlayer play];
}
else
{
[_queuePlayer insertItem:fakeNew afterItem:[_queuePlayer.items lastObject]];
}
NSLog(#"array of items to play:%lu", (unsigned long)_queuePlayer.items.count);
}
The problem is, that the method is called only for the first video that plays, after that, the method stops getting called, so if for example i have 2 movies in the array, it would play them both+the first one again, any idea why is this happening?
More Info:
also tried to make a new player every time and set it to layer. failed to send the notification more than once just the same
- (void)playerItemDidReachEnd:(NSNotification *)notification {
AVPlayerItem *p = [notification object];
[self.playList removeObjectAtIndex:0];
[self.playList addObject:p];
AVPlayer *newPlayer = [[AVPlayer alloc] initWithPlayerItem:[self.playList objectAtIndex:0]];
_player = newPlayer;
self.AVPlayerLayerView.layer.player = self.player;
[_player play];
}
After a lot of messing around, apparently for whatever reason, the view unregistered as observer every time, I just removed and added observer after every notification:
- (void)playerItemDidReachEnd:(NSNotification *)notification {
AVPlayerItem *p = [notification object];
AVPlayerItem *fakeNewItem = [[AVPlayerItem alloc] initWithAsset:p.asset];
[self.playList removeObjectAtIndex:0];
[self.playList addObject:fakeNewItem];
AVPlayer *newPlayer = [[AVPlayer alloc] initWithPlayerItem:[self.playList objectAtIndex:0]];
_player = newPlayer;
self.AVPlayerLayerView.layer.player = self.player;
[[NSNotificationCenter defaultCenter] removeObserver:self];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[_player currentItem]];
[_player play];
}
For a clean approach to resolve this issue. I approached with the next piece of code instead
The first is you have to add the code necessary to receive a feedback from the AVPlayer when the reproduction time changes.
- (void)addPeriodicTimeObserverForReproductionChanges {
#weakify(self);
[self.player
addPeriodicTimeObserverForInterval:CMTimeMakeWithSeconds(kBQDefaultTimeIntervalReproductionChanges, NSEC_PER_SEC)
queue:self.eventsQueue
usingBlock:^(CMTime time) {
#strongify(self);
[self dispatchBlockOnMainQueue:^{
if ([self.delegate respondsToSelector:#selector(playerItemController:didChangeReproductionTime:)])
[self.delegate playerItemController:self
didChangeReproductionTime:time];
[self checkForItemPlayToEnd];
}];
}];
}
- (void)checkForItemPlayToEnd
{
CMTime durationScaled = CMTimeConvertScale(self.duration,self.player.currentTime.timescale, kCMTimeRoundingMethod_Default);
if (CMTIME_COMPARE_INLINE(durationScaled, ==, self.player.currentTime)) {
[self playerDidFinishReproducingItem];
}
}
