How to play video using MPMoviePlayerController? - iphone

I am using the following code to play the video using the MPMoviePlayerController , but the video is not played. Can anyone tell me why ?
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"/one.mp4"];
NSString *mediaPath = [[[NSBundle mainBundle]resourcePath] stringByAppendingPathComponent:filePath];
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:mediaPath]];
[[moviePlayer view] setFrame:[[self view] bounds]];
[[self view] addSubview: [moviePlayer view]];
moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
[moviePlayer play];

It's pretty weird, but it seems to work okay if you make your MPMoviePlayerController a property instead of a local variable. Seems something is going on behind the scenes. I'm thinking it's related to ARC. Are you using ARC?
It's also an issue that you've over-appended your path:
// You've already got the full path to the documents directory here.
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"/one.mp4"];
// Now you're appending the full path to the documents directory to your bundle path
NSString *mediaPath = [[[NSBundle mainBundle]resourcePath] stringByAppendingPathComponent:filePath];
When I run your code in the simulator, the path looks like this:
/Users/mlong/Library/Application Support/iPhone
Simulator/5.1/Applications/8CFB9B94-BD6A-442C-A525-573FE343506D/VidoePlayer.app/Users/mlong/Library/Application Support/iPhone
Simulator/5.1/Applications/8CFB9B94-BD6A-442C-A525-573FE343506D/Documents/one.mp4
It should just be this:
/Users/mlong/Library/Application Support/iPhone
Simulator/5.1/Applications/8CFB9B94-BD6A-442C-A525-573FE343506D/Documents/one.mp4
So just delete this line:
NSString *mediaPath = [[[NSBundle mainBundle]resourcePath] stringByAppendingPathComponent:filePath];
And then change your player instantiation to this:
_moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:filePath]];
[[_moviePlayer view] setFrame:[[self view] bounds]];
[[self view] addSubview: [_moviePlayer view]];
_moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
[_moviePlayer play];
So you should add the MPMoviePlayerController as a property of your containing view controller.

All right, there is a big difference between the app bundle and the documents directory. I suggest you take a look at that.
First of all, Where is the video stored?
If your video is in the documents directory, don't append the documents directory path to the bundle path.
Just try with the filePath variable:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"/one.mp4"];
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL filePath]];
However, if the file is in the app bundle (you added it to your project in XCode), you should use what is in jinx response.

moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[moviePlayer.view setFrame:CGRectMake(//set rect frame)];
moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay=YES;
moviePlayer.repeatMode = NO;
[moviePlayer setFullscreen:YES animated:NO];
[moviePlayer prepareToPlay];
[self.view addsubview:movieplayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(MPMoviePlayerLoadStateDidChange:) name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
- (void)MPMoviePlayerLoadStateDidChange:(NSNotification *)notification {
if ((moviePlayer.loadState & MPMovieLoadStatePlaythroughOK) == MPMovieLoadStatePlaythroughOK) {
//add your code
}
}

Try asking your bundle directly and not setting up the file path manually
NSString *path = [[NSBundle mainBundle] pathForResource:#"name" ofType:#"mov"];

Player is initialized with the URL of the video which we want to be played (It can be either a path of local file of a device or a live URL.) after that player is added as a sub view of current view.
Supported video formats by MPMoviePlayerController class are following
.mov .mpv .3gp .mp4
I am not sure how much you this article would help you out. I am new to this. I worked on the step by step instructions provided in this article

MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:mediaPath]];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(movieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer];
hope Help it

It took me few mins to debug the problem but the answer is quite simple. Here is the deal:
If you want to MPMoviePlayerViewController to play from a web URL use this:
NSURL *url = [NSURL URLWithString:#"https://www.test.com/anyMovie.mp4"];
And if you want MPMoviePlayerViewController to play it from App Bundle use this:
NSString *moviePath = [[NSBundle mainBundle] pathForResource:#"anyMovie" ofType:#"m4v"];
NSURL *url = [NSURL fileURLWithPath:moviePath];
The Rest of it goes the same, except you have to set this property "movieSourceType" as follows:
MPMoviePlayerViewController *moviePlayerView = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
moviePlayerView.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[self presentViewController:moviePlayerView animated:YES completion:^{}];

Playing a video file saved in the app's documents directory

I have a video file saved in my app's local directory in the documents folder. I want to playback the file when the user clicks on the item in an embedded table view I created. My code for playing back the video is as follows:
NSString* documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString* path = [documentPath stringByAppendingPathComponent:#"DemoRecording.mp4"];
NSURL* movieURL = [NSURL fileURLWithPath: path];
[player.view setFrame: self.view.bounds];
[self.view addSubView: player.view];
[player play];
MPMoviePlayerViewController* moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL: movieURL];
[self presentMoviePlayerViewControllerAnimated: moviePlayer];
The video doesn't play back. The path is correct and the file exists there.
I know this is a repetitive question. I have referred to these links:
Playing a Downloaded Video from the Documents Directory with Cocoa-Touch
MPMoviePlayer load and play movie saved in app documents
But couldn't find a definitive answer.
Please help me out on this one. I am using iOS 5.1.1, if that changes anything.
EDIT:
It does work. I had forgotten to pass the URL to the movie player.
you can play Video from Document Directory like this way:-
-(IBAction)playVideo
{
NSURL *vedioURL;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory error:nil];
NSLog(#"files array %#", filePathsArray);
NSString *fullpath;
for ( NSString *apath in filePathsArray )
{
fullpath = [documentsDirectory stringByAppendingPathComponent:apath];
vedioURL =[NSURL fileURLWithPath:fullpath];
}
NSLog(#"vurl %#",vedioURL);
MPMoviePlayerViewController *videoPlayerView = [[MPMoviePlayerViewController alloc] initWithContentURL:vedioURL];
[self presentMoviePlayerViewControllerAnimated:videoPlayerView];
[videoPlayerView.moviePlayer play];
}
NOTE
Please note that don't Forget to include requested Framework or connect Delegate
The mistake in you was you missed / before DemoRecording.mp4
It should be
NSString* path = [documentPath stringByAppendingPathComponent:#"/DemoRecording.mp4"];
Also you are writing player statements before declaring it.

how to play mp4 file using html url IOS

I have been trying to play a mp4 file, I am receiving url from server, I have given that to MPMoviePlayerController, player is loading but file is not playing. Here is the code...
NSURL *url = [NSURL URLWithString:obj->msg_url]; // obj->url is a html php url not a direct file url.
moviePlayer = [[MPMoviePlayerController alloc]
initWithContentURL:url];
moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay = YES;
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];
So in this case how can I use MPMoviePlayerController to play from html url. Any idea?
thanks
Try
[moviePlayer play];
It seems shouldAutoplay does not always have the desired effect.
I have downloaded first and played its working now.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,#"sample.mp4"];
[urlData writeToFile:filePath atomically:YES];
NSURL *file_url = [NSURL fileURLWithPath:filePath];
moviePlayer = [[MPMoviePlayerController alloc]
initWithContentURL:file_url];
moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay = YES;
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];

Speed of Videos in iPhone App

For some reason the setcurrentPlayback Method does not work. Thanks for any thoughts...
-(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];
}
add the line
themovie.rate=2.f;
insted of [themovie setCurrentPlaybackRate:2.f]; line
may be its work....
sometime in use of HTML blog,this method not work so just try given 1 line
May be it is useful to you....

Play video stored in NSData

I am trying to play a video that is stored in an NSData object. I save the file to my applications temp folder and then try to play it, but all I get is a black screen. I can later browse to that folder and play the file, so I know that the file gets written and is supported.
This is my code:
NSString *urlString = [NSTemporaryDirectory() stringByAppendingPathComponent:#"test.m4v"];
NSURL *url = [[NSURL alloc] initWithString:urlString];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: url];
[moviePlayer prepareToPlay];
moviePlayer.view setFrame: self.view.bounds];
[self.view addSubview: moviePlayer.view];
[moviePlayer play];
The only thing I can think of is that it takes some time for the file to get written, and the player tries to access it before it is done. Is that possible, and if so, how do I fix it?
When working with files you should tell the NSURL that the URL should point to a
file:
NSString *urlString = [NSTemporaryDirectory() stringByAppendingPathComponent:#"test.m4v"];
NSURL *url = [NSURL fileURLWithPath:urlString];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: url];
[moviePlayer prepareToPlay];
moviePlayer.view setFrame: self.view.bounds];
[self.view addSubview: moviePlayer.view];
[moviePlayer play];

NSBundle pathforResource, where to place movie file

I'm not quite sure how pathForResource works. I wanted to play a movie from my app. I dragged it into XCode, checking the box to add it to subfolders and create directory if needed. I placed it in a separate folder called Videos. There is no Resources folder for this app (someone deleted it and thought it would be better to just have folders for each type of resource (img, vid, etc). So I'm not sure where to drop my movie, and how to access it using the NSBundle methods. This is what I have, but it does not seem to play.
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"test" ofType:#"m4v"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[moviePlayerController.view setFrame:CGRectMake(120, 120, 300, 200)];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;
[moviePlayerController play];
Thanks.
this code should list everything in your mainBundle
NSString *bundleRoot = [[NSBundle mainBundle] bundlePath];
NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:bundleRoot error:nil];
NSArray *files = [dirContents filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:#"self ENDSWITH '.m4v'"]];
NSLog(#"Directory Start");
NSLog(#"%#",dirContents);
NSLog(#"Directory End");
NSLog(#"files: %#",files);
Or you could just go to the ~user/Library/Application Support/iPhone Simulator and find you app and right click on it and show the content to see the directory structure of your app.
