A practical guide. Local MP4 video as background in iOS app. From iOS 8
I am trying to use a simple 13 second mp4 video as a background loop for my login screen.
I want the video to be automatic and looping. It has no audio and I don't need any controls.
I need buttons and other objects in front of it.
I tried to use WebView and make an MP4 GIF file from this tutorial: https://medium.com/swift-programming/ios-make-an-awesome-video-background-view-objective-c-swift-318e1d71d0a2
But the problem is my 5MB MP4 is (converted to GIF) 95MB in size.
I cannot use this method.
Is there a "Ease of Use" way?
EDIT:
Ok, this is what I have done now.
I've imported AVFoundation.
This is the code in the view
- (void)viewDidLoad {
[super viewDidLoad];
NSURL* mURL = [[NSBundle mainBundle] URLForResource:@"App-BG-Loop" withExtension:@"mp4"];
AVPlayer* player = [AVPlayer playerWithURL:mURL];
player.actionAtItemEnd = AVPlayerActionAtItemEndNone;
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[player currentItem]];
AVPlayerLayer* playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
playerLayer.frame = _videoView.bounds;
playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;
playerLayer.needsDisplayOnBoundsChange = YES;
[_videoView.layer addSublayer:playerLayer];
_videoView.layer.needsDisplayOnBoundsChange = YES;
[player play];
// Do any additional setup after loading the view, typically from a nib.}
- (void)playerItemDidReachEnd:(NSNotification *)notification {
AVPlayerItem *p = [notification object];
[p seekToTime:kCMTimeZero];}
This works fine in the iOS Simulator, but when I try to run it on the device it won't start and play the video. The look just stays white. There is no error.
Any idea?
EDIT 2:
The problem with not playing on the device was the size of the video, which was large. Apple only supports 1080p on devices.

I recently had to use animation too. I tried it with at first UIImageView
, but the memory management was not very good. I ended up creating .mp4 and used it in MPMoviePlayerController
:
-(void)setupDashboardAnimation
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(checkMovieStatus:)
name:MPMoviePlayerLoadStateDidChangeNotification
object:nil];
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:@"some_movie" ofType:@"some_extention"];
NSURL *movieURL = [NSURL fileURLWithPath:moviePath];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
_backgroundAnimationMoviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
_backgroundAnimationMoviePlayer.controlStyle = MPMovieControlStyleNone;
_backgroundAnimationMoviePlayer.repeatMode = MPMovieRepeatModeOne;
_backgroundAnimationMoviePlayer.view.backgroundColor = [UIColor clearColor];
for (UIView *aSubView in _backgroundAnimationMoviePlayer.view.subviews)
{
aSubView.backgroundColor = [UIColor clearColor];
}
[_backgroundAnimationMoviePlayer.view setFrame:imv_background.frame];
[_backgroundAnimationMoviePlayer prepareToPlay];
}
-(void)checkMovieStatus:(NSNotification *)notification
{
if (_backgroundAnimationMoviePlayer.loadState & (MPMovieLoadStatePlayable | MPMovieLoadStatePlaythroughOK) && _backgroundAnimationMoviePlayer.playbackState != MPMoviePlaybackStatePlaying)
{
[self.view insertSubview:_backgroundAnimationMoviePlayer.view aboveSubview:imv_background];
[_backgroundAnimationMoviePlayer play];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerLoadStateDidChangeNotification
object:nil];
dashboardAnimationDidSetup = YES;
}
}
