I am trying to play an mp4 after detecting a signal in the audio jack.
The video is playing once, after a delay of 1 sec which i dont want, and then application is freezing and i get this warning on the debugger: (only on the iphone, its working on simulation)
(8F190)/Symbols/System/Library/VideoDecoders/H264H4.videodecoder (file not found).
(8F190)/Symbols/System/Library/VideoDecoders/MP4VH4.videodecoder (file not found).
my code for the video is this :
//play video1
url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"sample1" ofType:#"mp4"]];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
moviePlayer.useApplicationAudioSession=NO;
[moviePlayer prepareToPlay];
moviePlayer.controlStyle = MPMovieControlStyleDefault;
[moviePlayer setMovieControlMode:MPMovieControlModeHidden];
moviePlayer.view.frame = CGRectMake(0, 0, 320, 480);
[self.view addSubview:moviePlayer.view];
[moviePlayer play];
I couldnt find anything on this warning on the net.
I have tried any kind of video encoding,according to the Apple docs.
We just cant play movies, does anyone have any idea how to fix it?
thanks .
If you run that code twice, the video won't play the second time, because you are creating a second MPMoviePlayerController and a second view, and only one MPMoviePlayerController view in your app can play video. So it works the first time but not the second time. You should be retaining your MPMovieVideoController in a property so that you can remove its view and release the MPMovieVideoController before trying to make a new one.

I am using MPMoviePlayerController to play .mp4 file, while I'm testing .mp4 recorded in windows platform its working fine, however .mp4 recorded using Android is not playing in my iOS device(iPod touch), Player keeps on buffering it.. Any Idea what could be the problem? And please help me, how to debug the issue in MPMoviePlayerController.
NSURL *file_url = [NSURL fileURLWithPath:filepath];
moviePlayer = [[MPMoviePlayerController alloc]
initWithContentURL:file_url];
moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay = YES;
// moviePlayer.useApplicationAudioSession = YES;
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];
thanks
I have found the problem, iOS not supporting the audio format, which is recorded in Android. Now I recorded using AAC it is playing fine.
I'm developing an iPhone app that can play online videos and
I want to play an ad first when the video data is loading.
First, I request an AdColony video Ad and begin to play it, then use MPMoviePlayerController to load video data, But when the video is prepared to play, it interrupts the previous Ad sound, and causes the ad to stop.
Here are the codes Im using:
// Play Ad first
[AdColony playVideoAdForSlot:1 withDelegate:self]; // It also use MPMoviePlayerController to play video
// Load video for playing
moviePlayer = [[MPMoviePlayerController alloc]
init];
moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
moviePlayer.controlStyle = MPMovieControlStyleNone;
moviePlayer.shouldAutoplay = NO;
moviePlayer.view.frame = CGRectMake(0,44,320,320);
moviePlayer.view.userInteractionEnabled = YES;
[moviePlayer prepareToPlay]; // Interrupt Ad playing
The offical doc said "calling prepareToPlay may interrupt the movie player’s audio session", so the Ad was interrupted. If I remove prepareToPlay, the video data will not be preloaded
I have tried to put
[AdColony playVideoAdForSlot:1 withDelegate:self]; below [moviePlayer prepareToPlay];
but it does not work. Does anyone know how to resolve it?
There are ways to handle interruptions,
read through he Apples guide

When i'm trying to play a movie on my iPhone, it isn't work. I dont know why.. searched here and all over the internet, try 5 different codes, but still can't get it to work. I'm new to Obj-C, so please be patient.
I just want the movie to play and when the movie is done, to exit the player. also, at the beginning I dont want it to show a black screen, I want to see the first frame of the video instead. is it possible?
-(void)playTheMovie
{
NSURL *url = [NSURL URLWithString:[[NSBundle mainBundle] pathForResource:#"C061381" ofType:#"mp4" inDirectory:#""]];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:url];
[[player view] setFrame:[self.view bounds]]; // Frame must match parent view
[self.view addSubview:[player view]];
[player play];
}
Thanks!
Most probably you are messing up with the URL.
Check out Movie player sample project from apple
https://developer.apple.com/library/ios/#samplecode/MoviePlayer_iPhone/Introduction/Intro.html
Run it first to confirm its functionality and then
Replace its movie with yours and change the extension and path name in the code
if it works copy the code to your project..
I have any number of thumbnail images that, when tapped, will play a different video (fullscreen). I have never been clear on whether I should keep one MPMoviePlayerController object in my view controller and have it play whichever url according to the thumbnail that was tapped, or create a new MPMoviePlayerController each time. What is the best practice?
I am also having problems where tapping on different thumbs crashes the app, I believe because the MPMoviePlayerController tries to stream a video while it is already trying to stream. There seems to be no way to cancel a MPMoviePlayerController and clear out what it was doing, then start loading a new video.
Here's how I create it:
MPMoviePlayerController* moviePlayer = [[MPMoviePlayerController alloc] init];
self.player = moviePlayer;
[moviePlayer release];
Then to play a video I do this:
//would like to do something like this first - [self.player clear];
self.player.contentURL = someURL;
[self.view addSubview:player.view];
[self.player prepareToPlay];
[self.player play];
Any advice is welcome... thanks.
When you are changing the video in an MPMovieplayerController,then you can remove the mpmoviecontrollerplayer view from super view using removeFromSuperView and again add it's subview to the super view initializing it with new URL.
No need to create new object every time.
I'm having trouble getting MPMoviePlayerController to work on the device. It runs fine in simulator, playing a five-second video and then sending the appropriate callback (myMovieFinishedCallback:) to the view controller. When it runs on the device, the movie never shows up, even though I can trace through [player play] with no problems. myMovieFinishedCallback: is never called, and there are no errors. All the right resources are being copied. Any idea what's going on?
Here's the code I use to create and use the player,
Update: I've switched over to using MPMoviePlayerViewController. On the device the movie still does not play, I just get the spinning progress wheel indefinitely. The controls also flash briefly even though I've set the player to MPMovieControlStyleNone - anybody know how I can fix this? The movie is five seconds and about 1.5 MB if that makes any difference.
Update: Other movie files work, but I can't figure out how to make mine work. I've tried it as a .mov and a .mp4 and the settings seem to be right. Any idea what would cause the MPMoviePlayer to show a progress wheel forever on the device only?
- (void) playMovie
{
NSString *url = [[NSBundle mainBundle]
pathForResource:#"myMovie"
ofType:#"mp4"];
MPMoviePlayerViewController *playerViewController =
[[MPMoviePlayerViewController alloc]
initWithContentURL:[NSURL fileURLWithPath:url]];
playerViewController.moviePlayer.controlStyle = MPMovieControlStyleNone;
playerViewController.moviePlayer.scalingMode = MPMovieScalingModeFill;
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(myMovieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:[playerViewController moviePlayer]];
playerViewController.view.frame = movieView.frame;
[movieView addSubview:playerViewController.view];
//---play movie---
MPMoviePlayerController *player = [playerViewController moviePlayer];
[player play];
}
Your code works fine for me, so there are two possibilities that come to mind (there may be others):
You movieView has not been properly initialized or has not had its frame set so that it's visible.
The video format of the video you're displaying isn't supported on the device.
I would try using a different video. Maybe one you can confirm you've played on the device before. Here's the little demo project I threw together: http://www.cimgf.com/files/PlayMovie.zip
