I'm wondering if it's possible to change the video playback speed in an iphone application. we want users to yell in the microphone to speed up the playback and get to the end.
You have to use setCurrentPlaybackRate:
There is a rate property for the AVPlayer.
If you take the example from Apple called "avPlayerDemo" in the resource section, you then simply have to set the mplayer.rate. It worked for me, I created a new slider in the xib files, implemented that slider in the AVPlayerDemoPlaybackViewController and simply set mPlayer.rate to the slider value.
What about the MPMoviePlayerController?
setCurrentPlaybackRate
Here's some code which does not work at that spot
-(IBAction)abspielen:(id)sender
{
NSString *titleOfButton = [sender titleForState:UIControlStateNormal];
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:titleOfButton ofType:#"mov"];
NSURL *movieURL = [ NSURL fileURLWithPath:moviePath];
MPMoviePlayerController *themovie = [[MPMoviePlayerController alloc]initWithContentURL: movieURL];
[themovie play];
[themovie setCurrentPlaybackRate:2.f];
[themovie release];
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
[self presentMoviePlayerViewControllerAnimated:moviePlayer];
[moviePlayer release];
}

I use the MPMoviePlayerController for playing video. It works, but it displays unknown strings which I think it is related to its localization files:
The code for playing video is here:
NSString *videoPath = [[NSBundle mainBundle] pathForResource:#"test" ofType:#"m4v"];
NSURL *streamURL = [NSURL fileURLWithPath:videoPath];
MPMoviePlayerController *moviplayer =[[MPMoviePlayerController alloc] initWithContentURL: streamURL];
[moviplayer prepareToPlay];
[moviplayer.view setFrame: self.view.bounds];
[self.view addSubview: moviplayer.view];
moviplayer.fullscreen = YES;
moviplayer.shouldAutoplay = YES;
moviplayer.repeatMode = MPMovieRepeatModeNone;
moviplayer.movieSourceType = MPMovieSourceTypeFile;
[moviplayer play];
How to solve this problem?
After looking to all part of my project, I find that the below class (category) which is used to set the default language for the application, yields to this bug:

Use this forked class solved my problem by not use swizzling method for UIKit bundle:

Looking to add a video to my apps intro screen like the Uber app. I am sure there are others.
I found this which uses a gif and UIWebView, but not sure if this is the best solution. I definitely don't want to use images and stitch them together (would rather not have video if that is the preferred method).

This is what I use in my app Letsplay, The answer from Aslam will work but uses MPmoviePlayerController which is depreciated as of IOS 9.0.
Also I set the video gravity so that your video will fill the entire frame which means no black borders.
NSString *videoPath = [[NSBundle mainBundle] pathForResource:#"icebergs" ofType:#"mp4"];
NSURL *videoURL = [[NSURL alloc] initFileURLWithPath: videoPath];
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithAsset:[AVURLAsset URLAssetWithURL:videoURL options:nil]];
AVPlayer* videoPlayer = [AVPlayer playerWithPlayerItem:playerItem];
AVPlayerLayer* videoPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:videoPlayer];
[videoPlayerLayer setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
[self.view.layer addSublayer:videoPlayerLayer];
[videoPlayerLayer setVideoGravity:AVLayerVideoGravityResizeAspectFill];
[videoPlayer play];
If you don't want sound then remember to mute the player
[videoPlayer setMuted:YES];
I haven't tried the code, but I it should work. It generally takes the path of the video file and adds it to the view controller. You may have to set the coordinates and size. Though I have used here video, GIF is more preferred.
- (void)viewDidAppear:(BOOL)animated
{
[self loadVideoInBackgroundOfView];
}
-(void)loadVideoInBackgroundOfView{
MPMoviePlayerController* videoPlayer = [[MPMoviePlayerController alloc] initWithContentURL:[self getTheVideoPath]];
[videoPlayer.view setFrame:self.view.bounds];
[self.view insertSubview:moviePlayer.view atIndex:0];
[videoPlayer prepareToPlay];
[videoPlayer play];
}
-(NSURL*)getTheVideoPath{
NSString *path = [[NSBundle mainBundle] pathForResource:#"VideoFileName" ofType:#"mp4"];
NSURL *URL = [NSURL fileURLWithPath:path];
return URL;
}
i want to play video in ios one after another..I have two video files .m3u8 format. if video one completed then video two start automatically.. after video two complete then again video one should played automatically. and again video two should start automatically. how can i do this thing….I am using Mediaplayer framework. plz give me any idea…..Thanks in advance.
-(void)viewDidLoad
{
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"buyTutorial" ofType:#“m3u8”];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;
[moviePlayerController prepareToPlay];
[moviePlayerController play];
[self setController:moviePlayerController];
}
You should be able to use this notification:
https://developer.apple.com/LIBRARY/IOS/documentation/MediaPlayer/Reference/MPMoviePlayerController_Class/index.html#//apple_ref/c/data/MPMoviePlayerPlaybackDidFinishNotification
And then look for this constant PlaybackEnded:
https://developer.apple.com/LIBRARY/IOS/documentation/MediaPlayer/Reference/MPMoviePlayerController_Class/index.html#//apple_ref/c/tdef/MPMovieFinishReason
Then just start the next movie in your playback queue.
Here's some examples on how to register to the notification:
MPMoviePlayerPlaybackDidFinishNotification being called again in iPhone 4.3 simulator when setting contentURL
So I created a view that has a button in it that will play the movie.
Here is the action for that button:
- (IBAction)playMovie {
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:#"sample_iPod" ofType:#"m4v"];
NSURL *movieURL = [NSURL fileURLWithPath:moviePath];
MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
theMovie.scalingMode = MPMovieScalingModeAspectFill;
[theMovie play];
}
However when I test the App and try to play the video the screen stays blank and in the log it shows this:
[Switching to process 9333 thread 0x13c03]
Any Idea what's up?
Thanks
You need to set the bounds of the player, and add the player's view to self.view:
[theMovie.view setFrame: self.view.bounds]; // player's frame must match parent's
[self.view addSubview: theMovie.view];
