I am developing for iOS 6 using Xcode 4.6.1 (Target is iPad)
I am trying to change the video URL when the user swipes the screen.
This is my ViewController.m file:
#import "ViewController.h"
#interface experiencesViewController () {
MPMoviePlayerViewController *playerViewController;
MPMoviePlayerController *player;
}
#end
...
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
NSString *url = [[NSBundle mainBundle] pathForResource:"video" ofType:#"mp4"];
playerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:url]];
player = [playerViewController moviePlayer];
[player setMovieSourceType:MPMovieSourceTypeFile];
player.fullscreen = YES;
[player play];
...
}
...
Now, I want to change the video on a swipe event. I tried doing this:
- (IBAction)didSwipeLeft:(UITapGestureRecognizer *)recognizer {
NSLog(#"Left");
player.movieSourceType = MPMovieSourceTypeFile;
player.contentURL = [NSURL URLWithString:#"video2.mp4"];
[player prepareToPlay];
[player play];
}
However, this doesn't work. The video stops playing and nothing happens after that. Any help would be highly appreciated.
Thanks :)
remove the [player play] because the video is not yet ready to play.

My app has a start page and a second page with buttons that play videos. When a video is finished the AVPlayer is dismissed with playerItemDidReachEnd. But for some reason it shows the start page and not the second page when the player is dismissed. How can I get it to show the second page instead?
#import "ViewController.h"
#import AVKit;
#import AVFoundation;
#interface ViewController ()
#property(nonatomic, readonly) AVPlayerItem *currentItem;
#end
#implementation ViewController
AVPlayerViewController *playerViewController;
- (void)viewDidLoad {
[super viewDidLoad];
playerViewController = [[AVPlayerViewController alloc] init];
}
-(void)playerItemDidReachEnd:(NSNotification *) notification {
//remove the player
[self dismissViewControllerAnimated:NO completion:nil];
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
- (IBAction)playVideo:(id)sender {
NSURL *url = [NSURL URLWithString:#"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"];
AVURLAsset *asset = [AVURLAsset assetWithURL: url];
AVPlayerItem *item = [AVPlayerItem playerItemWithAsset: asset];
AVPlayer * player = [[AVPlayer alloc] initWithPlayerItem: item];
playerViewController.player = player;
UIScreen *mainScreen = [UIScreen mainScreen];
CGRect viewRect = mainScreen.bounds;
playerViewController.view.frame = viewRect;
playerViewController.showsPlaybackControls = YES;
[self.view addSubview:playerViewController.view];
[player play];
/* When the player item has played to its end time we'll dismiss the controller */
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:playerViewController.player.currentItem];
}
#end
If I understand your code correctly, your "second page" is ViewController.
You are adding AVPlayerViewController by [self.view addSubview:playerViewController.view];, so you need to remove this view by calling
[playerViewController.view removeFromSuperview].
After [self dismissViewControllerAnimated:NO completion:nil];, you dismiss whole ViewController, not only AVPlayerViewController.
I've been through all the posts in StackOverflow but I can't get a full example of how to get a video from the bundle and reproduce it in a controller.
I've tried many things but my screen appeared blank or black.
In the last amend, my video remains like this:
no error is thrown on the log. This is my code:
.h (please ignore the name of the controller, it will be finally a camera)
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#import <AVKit/AVKit.h>
#interface NativeCameraViewController : UIViewController
#end
.m
#import "NativeCameraViewController.h"
#interface NativeCameraViewController ()
#property (nonatomic, retain) AVPlayerViewController *avPlayerViewcontroller;
#end
#implementation NativeCameraViewController
- (void)viewDidLoad {
[super viewDidLoad];
UIView *view = self.view;
NSString *stringPath = [[NSBundle mainBundle]pathForResource:#"video" ofType:#"mov"];
NSURL *fileURL = [NSURL fileURLWithPath:stringPath];
AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc] init];
playerViewController.player = [AVPlayer playerWithURL:fileURL];
self.avPlayerViewcontroller = playerViewController;
[self resizePlayerToViewSize];
[view addSubview:playerViewController.view];
view.autoresizesSubviews = TRUE;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void) resizePlayerToViewSize
{
CGRect frame = self.view.frame;
NSLog(#"frame size %d, %d", (int)frame.size.width, (int)frame.size.height);
self.avPlayerViewcontroller.view.frame = frame;
}
#end
and that's what I've got so far.
My video is correctly on the Bundle, called video.mov:
I've tried both linking and copying. Same result.
What am I doing wrong??
Thank you very much in advance.
I'd like to avoid using MPMoviePlayerController since it's deprecated in iOS9
It was actually my fault...
I was trying to reproduce an alias.
When you have 20.000 videos and 30.000 resources this things happen.
Instead of using AVPlayer, use MPMoviePlayerController class:
NSString *path = [[NSBundle mainBundle] pathForResource:#"video" ofType:#"mov"];
NSURL *url = [NSURL fileURLWithPath:path];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:url];
[player play];
I want to play a loop background video in my view. I wrote this code :
-(AVPlayerLayer*)playerLayer{
if(!_playerLayer){
// find movie file
NSString *moviePath = [[NSBundle mainBundle] pathForResource:#"fond_login" ofType:#"mp4"];
NSURL *movieURL = [NSURL fileURLWithPath:moviePath];
_playerLayer = [AVPlayerLayer playerLayerWithPlayer:[[AVPlayer alloc]initWithURL:movieURL]];
_playerLayer.frame = CGRectMake(0,0,self.view.frame.size.width, self.view.frame.size.height);
[_playerLayer.player play];
return _playerLayer;
}
return nil; }
-(void)replayMovie:(NSNotification *)notification {
NSLog(#"Finis");
[self.playerLayer.player play];}
And in my viewdidload, I have :
[self.view.layer addSublayer:self.playerLayer];
[[NSNotificationCenter defaultCenter] addObserver: self
selector: #selector(replayMovie:)
name: AVPlayerItemDidPlayToEndTimeNotification
object:nil];
My problem is that the video don't play in loop. I see the video one time and it's finish. I don't know why ..
Thank's
EDIT :
I see another tutorial.
#import MediaPlayer;
#property (nonatomic, strong) MPMoviePlayerController *moviePlayer;
My code in viewDidLoad :
NSURL *videoURL = [[NSBundle mainBundle] URLForResource:#"my_video" withExtension:#"format"];
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
self.moviePlayer.controlStyle = MPMovieControlStyleNone;
self.moviePlayer.scalingMode = MPMovieScalingModeAspectFill;
self.moviePlayer.view.frame = self.view.frame;[self.view insertSubview:self.moviePlayer.view atIndex:0];
[self.moviePlayer play];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(loopVideo) name:MPMoviePlayerPlaybackDidFinishNotification object:self.moviePlayer];
And :
- (void)loopVideo {
[self.moviePlayer play]; }
It's work perfectly.
In your replayMovie: method you need to seek back to the beginning:
- (void)replayMovie:(NSNotification *)notification {
[(AVPlayerItem *)notification.object seekToTime:kCMTimeZero];
}
You're also going to want to set the actionAtItemEnd of the AVPlayer so it doesn't pause:
_playerLayer.player.actionAtItemEnd = AVPlayerActionAtItemEndNone;
Seems to be similar questions asked but none of the solutions seem to work for me. Cant for the life of me understand why my code doesnt work so here it is.
I dont get any errors but also get no sound.
#interface MainApp ()
#property (strong, nonatomic) AVAudioPlayer *audioPlayer;
-(void)playSoundFX:(NSString*) soundFile;
#end
#implementation MainApp
- (void)viewDidLoad {
[super viewDidLoad];
// Play sound
[self playSoundFX:#“sound.mp3"];
}
// Play sound
- (void)playSoundFX:(NSString*)soundFile {
// Setting up path to file url
NSBundle* bundle = [NSBundle mainBundle];
NSString* bundleDirectory = (NSString*)[bundle bundlePath];
NSURL *url = [NSURL fileURLWithPath:[bundleDirectory stringByAppendingPathComponent:soundFile]];
// Make an audioPlayer object and play file
NSError *error;
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
[audioPlayer setVolume:100.0f];
if (audioPlayer == nil)
NSLog(#"%#", [error description]);
else
[audioPlayer play];
}
#end
*********vvvvvvvvv Amended Code that works vvvvvvvvv**********
#interface MainApp ()
#property (strong, nonatomic) AVAudioPlayer *audioPlayer;
-(void)playSoundFX:(NSString*) soundFile;
#end
#implementation MainApp
- (void)viewDidLoad {
[super viewDidLoad];
// Play sound
[self playSoundFX:#“sound.mp3"];
}
// Play sound
- (void)playSoundFX:(NSString*)soundFile {
// Setting up path to file url
NSBundle* bundle = [NSBundle mainBundle];
NSString* bundleDirectory = (NSString*)[bundle bundlePath];
NSURL *url = [NSURL fileURLWithPath:[bundleDirectory stringByAppendingPathComponent:soundFile]];
// Make an audioPlayer object and play file
NSError *error;
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
[self.audioPlayer setVolume:100.0f];
if (self.audioPlayer == nil)
NSLog(#"%#", [error description]);
else
[self.audioPlayer play];
}
#end
I am execute your code on my iPhone. It is work properly.Please Select a device and run your code. I hope it will execute properly with sound.
You got to segregate the functionalities..
Loading audio file in viewDidLoad and play it on play action, some thing like this
#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>
#interface ViewController ()
{
AVAudioPlayer *_audioPlayer;
}
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Construct URL to sound file
NSString *path = [NSString stringWithFormat:#"%#/sound.mp3", [[NSBundle mainBundle] resourcePath]];
NSURL *soundUrl = [NSURL fileURLWithPath:path];
// Create audio player object and initialize with URL to sound
_audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl error:nil];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)playSoundTapped:(id)sender
{
// When button is tapped, play sound
[_audioPlayer play];
}
This player only have 2 buttons,play/pause and fullscreen,it looks like a system player,so fast and simple.
I used UIWebView and HTML5 inside the UIView,but UIWebView is so slow and can not play without fullscreen.
If this player is a UIObject or some UIView things,how can I add it?
thanks~
The MPMoviePlayerController is deprecated from iOS 9.
You can insert a video into iOS project with AVPlayerViewController now.
For example:
#import <AVFoundation/AVFoundation.h>
#import <AVKit/AVKit.h>
...
#property (nonatomic, retain) AVPlayerViewController *playerViewController;
...
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *stringVideoName = #"video.m4v";
NSString *stringVideoPath = [[NSBundle mainBundle] pathForResource:stringVideoName ofType:nil];
NSAssert(stringVideoPath, #"Expected not nil video file");
NSURL *urlVideoFile = [NSURL fileURLWithPath:stringVideoPath];
NSAssert(urlVideoFile, #"Expected not nil video url");
_playerViewController = [[AVPlayerViewController alloc] init];
_playerViewController.player = [AVPlayer playerWithURL:urlVideoFile];
_playerViewController.view.frame = self.view.bounds;
_playerViewController.showsPlaybackControls = YES;
[self.view addSubview:_playerViewController.view];
self.view.autoresizesSubviews = YES;
}
You can add a video player into your UIView using MPMoviePlayerController.
Here is Apple sample code which does just like this.
It can stream a video from internet as well as play a local movie file.
You can change the playback controls by changing the moviePlayer controlStyle property.
You can find the sample code from the link below
http://developer.apple.com/library/ios/#samplecode/MoviePlayer_iPhone/Introduction/Intro.html
Improts Following frameworks
#import <MediaPlayer/MediaPlayer.h>
#import <AVFoundation/AVFoundation.h>
#import <AVKit/AVKit.h>
#import <UIKit/UIKit.h>
Add following code in UIView Or UIViewController Class
videoView is UIView
// Url of Video
NSURL *videoURL = [NSURL URLWithString:#"urlOfVideo"];
// Init Player
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
AVPlayerViewController *playerViewController = [AVPlayerViewController new];
// Add Player in AVPlayerViewController
playerViewController.player = player;
playerViewController.showsPlaybackControls = true;
// Set Frame accoding to view
playerViewController.view.frame = _videoView.bounds;
//Used to Play On start
[playerViewController.player play];
// Add Video in UIView
[_videoView addSubview:playerViewController.view];
I hope it will work for you...
