I use a MPMoviePlayerController to play audio (ex: http://www.stanford.edu/group/edcorner/uploads/podcast/ballmer090506.mp3) or video (ex: http://video.ted.com/talk/podcast/2011U/None/RicElias_2011U.mp4)
myMoviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theURL];
myMoviePlayer.view.frame = CGRectMake(-80, 80, 480, 320);
myMoviePlayer.controlStyle = MPMovieControlStyleFullscreen;
myMoviePlayer.movieSourceType = MPMovieSourceTypeFile;
myMoviePlayer.scalingMode = MPMovieScalingModeAspectFit;
myMoviePlayer.useApplicationAudioSession = TRUE;
[myMoviePlayer prepareToPlay];
[myMoviePlayer play];
It works well, my only one problem is during the loading time (between 5s and 20s if I have a bad 3G reception), I have a black screen.
I would like to have MPMoviePlayerController diplayed with the "Loading..." label and the UIActiviyIndicator in his top bar during this time, like YouTube videos.
How can I do that?
Thanks.
Just use MPMoviePlayerViewController instead of MPMoviePlayerController. It should do what you want.

I created an app for streaming audio (and send mail as well) but I have a problem, my app will not keep playing after I press the home button.
I use XCODE 6.4 and the mediaplayer.framework to play the stream it is in viewcontroller and I have been activating the background mode Audio & airplay.
Can someone please let me know what I am doing wrong here, I really want to learn it.
code:
NSURL *videoStreamURL = [NSURL URLWithString:#"http://streamlink.m3u"];
_player = [[MPMoviePlayerController alloc] initWithContentURL:videoStreamURL];
_player.view.frame = CGRectMake(0, 530, self.view.frame.size.width, 38);
[self.view addSubview:_player.view];
[_player play];
I am using the below code to play the video, but its working fine while using the local url that mean resourse file path. Not working for server url.
player = [[MPMoviePlayerViewController alloc] initWithContentURL:urlvalue];
player.view.frame = CGRectMake(10, 10, 800, 800);
player.moviePlayer.shouldAutoplay=YES;
player.moviePlayer.movieSourceType= MPMovieSourceTypeFile;
[player.moviePlayer setControlStyle:MPMovieControlStyleDefault];
[self.view addSubview:player.view];
[player.moviePlayer prepareToPlay];
[player.moviePlayer play];
Kindly correct me if I missed out something. Thanks in advance.
Pay attention on iOS 9 App transport security. If you haven't set it up, streaming will fail with black empty screen.
Change movieSourceType from File to Streaming :
player.moviePlayer.movieSourceType= MPMovieSourceTypeStreaming;
Note : url should be a streaming url not physical file path
I want to create an app which has a default image as the background of a view that has many buttons on it. When a user clicks on any of the buttons, a unique video plays. The buttons are gonna be almost transparent so, I want the video to play in the background of the same view itself (replacing/playing above the image) and not open in a new Player(as it does using the media player). Has anyone tried it, or does anyone have any idea?
Thank You!
#import <MediaPlayer/MPMoviePlayerController.h>
MPMoviePlayerController* moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: [NSURL fileURLWithPath: moviePath]];
moviePlayer.controlStyle = MPMovieControlStyleNone;
[RootViewController.view insertSubview: moviePlayer.view aboveSubview: myView];
[moviePlayer play];
I embedded a MPMoviePlayerController on my mail view. I can play/pause the movie and seek forward/backward. But when I touch the "fullscreen button" the movie stops and the playback state is set to MPMoviePlaybackStateStopped... Should the movie be played in full screen?
Here is my code:
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:videoUrl];
player.shouldAutoplay = NO;
player.movieSourceType = MPMovieSourceTypeFile;
player.controlStyle = MPMovieControlStyleEmbedded;
player.allowsAirPlay = YES;
player.view.frame = CGRectMake(xPos, yPos, width, height);
[self.view addSubview:player.view];
I found my bug: when pressing the full screen toggle button in MPMoviePlayerController's view, the method "viewWillLayoutSubviews" is invoked. I could never imagine this behavior...
I hope my experience can be useful to other developers.
Remember that any containing ViewController will have its viewWillDisappear, viewDidDisappear methods invoked when the MPMoviePlayerController goes full screen. Also, viewWillAppear and viewWillDisappear get called when it comes back from full screen.
If you have any logic in there that affects video playback behavior, it'll get called unless you use some conditional logic to see if the video is still playing.
I'm writing an application where the user can record up to 6 video clips each with a duration of 2 seconds. When the video clips are recorded the user can play with them using 6 buttons - one for each clip. The user can then record a movie by switching between the 6 clips. The problem is that I need near instantaneous switching between the 6 clips when the user presses a button - otherwise the illusion of playing with the clips is lost - the functionality is somewhat similar to the app called CamBox in the App Store.
I first tried initializing every clip with and AVAsset in an AvPlayerItem in an AVPlayer every time the user pressed a button. The output of the player was directed at a an AVPlayerLayer in my main view. The problem is that the time it takes to load and start playing is quite long, meaning the the video lags when the user presses the buttons in rapid succession.
I the decided to try to preload all the clips using 5 AVPlayers and 5 AVPlayerLayers. The 5 PlayerLayers are inserted into my main view and when the user presses a button the currently playing AVPlayer is paused and rewound and the the currently visible AVPlayerLayer is hidden. The new AVPlayer is started and the corresponding AVPlayerLayer is shown. It works pretty ok being much faster than my first solution although not instantaneous but the problem is that I can only preload 4 clips meaning than when the user presses the button that play the last two the it lags big time. Below is my code to preload the clips
-(void)loadVideos
{
layers = [[NSMutableArray alloc] initWithCapacity:6];
players = [[NSMutableArray alloc] initWithCapacity:6];
for(int i = 1; i < 7; i++)
{
NSURL* fileURL = [NSURL fileURLWithPath:[self getFileName:i]];
AVPlayerItem* avPlayerItem = [[[AVPlayerItem alloc] initWithURL:fileURL] autorelease];
[avPlayerItem addObserver:self forKeyPath:#"status" options:0 context:nil];
AVPlayer *avPlayer = [[[AVPlayer alloc] initWithPlayerItem:avPlayerItem] autorelease];
[avPlayer addObserver:self forKeyPath:#"status" options:0 context:nil];
[avPlayer addObserver:self forKeyPath:#"currentItem" options:0 context:nil];
AVPlayerLayer* layer = [AVPlayerLayer playerLayerWithPlayer:avPlayer];
layer.frame = self.playerView.bounds;
[playerView.layer addSublayer:layer];
[layers addObject:layer];
[players addObject:avPlayer];
layer.hidden = YES;
}
}
The event handler for the 6 buttons looks like this:
- (IBAction)takeBtnClicked:(id)sender {
int tag = ((UIButton*)sender).tag;
AVPlayer* player;
AVPlayerLayer* layer;
if (layerIndex > -1) {
player = [players objectAtIndex:layerIndex];
layer = [layers objectAtIndex:layerIndex];
[player pause];
layer.hidden = YES;
[player seekToTime:kCMTimeZero];
}
layerIndex = tag-1;
player = [players objectAtIndex:layerIndex];
layer = [layers objectAtIndex:layerIndex];
[player play];
layer.hidden = NO;
}
I'm prette sure that the limitation of 4 preloaded video clips is a hardware limitation, but what is the alternative. Does anybody have any ideas?
Thanks in advance.
See my answer for iphone-smooth-transition-from-one-video-to-another, it shows a library you can use to implement this logic and an example app with 3 buttons that kick off animated clips. Each clip also has an associated sound effect.
