Im trying to download a video/audio on iphone and store in iPhone system bundle, and play the video/audio file from bundle.
I have successfully downloaded the video/audio file using NSURLConnection.
and i have store it as "sample.mov"
but i wasn't able to play the video from bundle. is it because the file was not registered in bundle?!
Here is the code:
write to file when finish downloading
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"sample.mov"];
[VideoData writeToFile:path atomically:YES];
}
then i play the video from bundle
MoviePlayerAppDelegate *appDelegate = (MoviePlayerAppDelegate *)[[UIApplication sharedApplication] delegate];
// play the movie
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:#"a" ofType:#"mov"];
NSURL *movURL = [NSURL fileURLWithPath:moviePath];
[appDelegate initAndPlayMovie:movURL];
-(void)initAndPlayMovie:(NSURL *)movieURL
{
MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
if (mp)
{
// save the movie player object
self.moviePlayer = mp;
[mp release];
// Apply the user specified settings to the movie player object
[self setMoviePlayerUserSettings];
// Play the movie!
[self.moviePlayer play];
}
}
To my knowledge you cannot successfully save files to resource bundle folder.

I am using this for reference: Getting thumbnail from a video url or data in IPhone SDK
The method is using the MPMoviePlayerController class instead of the AVFoundation, and I think I want to use that as well because the people said that MPMoviePlayer way is faster than the AVFoundation way.
The problem is, the method used to create the thumbnails, [player thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame] is deprecated in iOS 7.0.
By looking at the apple docs, the remaining supported ways to create thumbnails are by the methods (void)requestThumbnailImagesAtTimes:(NSArray *)playbackTimes timeOption:(MPMovieTimeOption)option and (void)cancelAllThumbnailImageRequests. But, as the method signatures dictate, these methods return nothing. So how do I access the UIImage thumbnail created by these methods?
If it helps, this is what I have so far in terms of code:
self.videoURL = info[UIImagePickerControllerMediaURL];
NSData *videoData = [NSData dataWithContentsOfURL:self.videoURL];
//Create thumbnail image
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:self.videoURL];
[player requestThumbnailImagesAtTimes:#[#1] timeOption:MPMovieTimeOptionNearestKeyFrame];
//UIImage *thumbnail = ???
How do I get a UIImage reference to the thumbnail?
EDIT
I figured out how to create a notification for the thumbnail image request (using this question as reference). However, I realise that this method works asynchronously from the main thread, and so my notification handler method doesn't seem to ever be called.
This is what I have now.
self.videoURL = info[UIImagePickerControllerMediaURL];
NSData *videoData = [NSData dataWithContentsOfURL:self.videoURL];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:self.videoURL];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(handleThumbnailImageRequestFinishNotification:) name:MPMoviePlayerThumbnailImageRequestDidFinishNotification object:player];
[player requestThumbnailImagesAtTimes:#[#1] timeOption:MPMovieTimeOptionNearestKeyFrame];
And then my handler method:
-(void)handleThumbnailImageRequestFinishNotification:(NSNotification*)notification
{
NSDictionary *userinfo = [notification userInfo];
NSError* value = [userinfo objectForKey:MPMoviePlayerThumbnailErrorKey];
if (value != nil)
{
NSLog(#"Error creating video thumbnail image. Details: %#", [value debugDescription]);
}
else
{
UIImage *thumbnail = [userinfo valueForKey:MPMoviePlayerThumbnailImageKey];
}
But the handler never gets called (or so it appears).
Try this way.
import AVFoundation framework
in *.h
#import <AVFoundation/AVFoundation.h>
in *.m
AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:self.urlForConevW options:nil];
AVAssetImageGenerator *generateImg = [[AVAssetImageGenerator alloc] initWithAsset:asset];
NSError *error = NULL;
CMTime time = CMTimeMake(1, 65);
CGImageRef refImg = [generateImg copyCGImageAtTime:time actualTime:NULL error:&error];
NSLog(#"error==%#, Refimage==%#", error, refImg);
UIImage *FrameImage= [[UIImage alloc] initWithCGImage:refImg];
Here is a code to make a thumbnail of the video and save the images to the DocumentDirectory..
//pass the video_path to NSURL
NSURL *videoURL = [NSURL fileURLWithPath:strVideoPath];
AVURLAsset *asset1 = [[AVURLAsset alloc] initWithURL:videoURL options:nil];
AVAssetImageGenerator *generator = [[AVAssetImageGenerator alloc] initWithAsset:asset1];
generator.appliesPreferredTrackTransform = YES;
//Set the time and size of thumbnail for image
NSError *err = NULL;
CMTime thumbTime = CMTimeMakeWithSeconds(0,30);
CGSize maxSize = CGSizeMake(425,355);
generator.maximumSize = maxSize;
CGImageRef imgRef = [generator copyCGImageAtTime:thumbTime actualTime:NULL error:&err];
UIImage *thumbnail = [[UIImage alloc] initWithCGImage:imgRef];
//And you can save the image to the DocumentDirectory
NSData *data = UIImagePNGRepresentation(thumbnail);
//Path for the documentDirectory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
[data writeToFile:[documentsDirectory stringByAppendingPathComponent:currentFileName] atomically:YES];
If your URL is to an HTTP live stream, then it won't return anything, per the docs. For a file URL, I found that I had to start the request after playing the movie, or it would never get called.
I am using this code with autolayout view controller and playing this video in another view called videoView but it is not playing the video in fullscreen.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:saveFileName];
NSURL *url1 = [[NSURL alloc] initFileURLWithPath: path];
videoPlayer = [AVPlayer playerWithURL:url1] ;
self.avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:videoPlayer];
avPlayerLayer.frame = self.videoView.bounds;
[self.videoView.layer addSublayer: avPlayerLayer];
[videoView setHidden:NO];
[self.videoPlayer play];
Use MPMPMoviePlayerViewController,
MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] initWithContentURL:url1];
NSError *_error = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: &_error];
[self presentMoviePlayerViewControllerAnimated:mpvc];
I tried this with no luck:
NSData *imageData = UIImageJPEGRepresentation([sight.photo valueForKey:#"image"], 0.8);
NSString *docsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [docsPath stringByAppendingPathComponent:#"sound.m4a"];
NSURL *fileUrl = [NSURL fileURLWithPath:filePath];
NSData *aacData = [sight.sound valueForKey:#"soundrecord"];
[aacData writeToURL:fileUrl atomically:YES];
// NSString *text = self.textField.text;
NSArray *items = #[imageData, aacData];
Yes, but you need to pass the audio file URL to the activity sheet rather than the NSData.
NSString *docPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
NSString *filePath = [docPath stringByAppendingPathComponent:#"sound.aac"];
NSURL *fileUrl = [NSURL fileURLWithPath:filePath isDirectory:NO];
NSArray *activityItems = #[fileUrl];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
[self presentViewController:activityVC animated:YES completion:nil];
If you find that the attachment doesn't appear when launching the email composer from the activity sheet, make sure your file path and URL are correct and that the file exists (including the extension on the device/simulator drive).
To open a file on the simulator, go to folder (~/Library/Application Support/iPhone Simulator/...
To check the file name on device, go to XCode Organizer Window and select the Applications tab within the debugging device connected. You should see the file structure on the main panel.
I'm trying to get an audio file playing in my iOS app. This is my current code
NSString *soundFilePath = [NSString stringWithFormat:#"%#/test.m4a", [[NSBundle mainBundle] resourcePath]];
NSLog(#"%#",soundFilePath);
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[audioPlayer setVolume:1.0];
audioPlayer.delegate = self;
[audioPlayer stop];
[audioPlayer setCurrentTime:0];
[audioPlayer play];
I've being checking a bunch of other posts but they all generally do the same thing. I'm not getting an error, but I don't hear any audio playing on the simulator or device.
This is the path I get for the audio file on the simulator
/Users/username/Library/Application Support/iPhone Simulator/5.1/Applications/long-numbered-thing/BookAdventure.app/test.m4a
Any help is appreciated!
Maybe you should try using the NSBundle method pathForResource:ofType: method to create the path to the file.
The following code should successfully play an audio file. I have only used it with an mp3, but I imagine it should also work with m4a. If this code does not work, you could try changing the format of the audio file. For this code, the audio file is located in the main project directory.
/* Use this code to play an audio file */
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"test" ofType:#"m4a"];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
player.numberOfLoops = -1; //Infinite
[player play];
EDIT
Ok, so try this:
NSString *soundFilePath = [NSString stringWithFormat:#"%#/test.m4a",[[NSBundle mainBundle] resourcePath]];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
player.numberOfLoops = -1; //Infinite
[player play];
Also, make sure you do the proper imports:
#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>
You need to store a strong reference to 'AVAudioPlayer'
#property (strong) AVAudioPlayer *audioPlayer;
And if you are sure that your audio file is in following Bundle Resources, it should play.
Project>Build Phases>Copy
To play file with extension .caf, .m4a, .mp4, .mp3,.wav, .aif
Download following two files from GitHub
SoundManager.h
SoundManager.m
Add these files to your project
Also add audio files to resource folder (sample files)
mysound.mp3, song.mp3
Import header file in desired file
#import "SoundManager.h"
And add following two lines in -(void)viewDidLoad
[SoundManager sharedManager].allowsBackgroundMusic = YES;
[[SoundManager sharedManager] prepareToPlay];
Use following line to play sound (mysound.mp3)
[[SoundManager sharedManager] playSound:#"mysound" looping:NO];
Use following line to stop the sound (mysound.mp3)
[[SoundManager sharedManager] stopSound:#"mysound"];
Also you can play music (song.mp3) as
[[SoundManager sharedManager] playMusic:#"song" looping:YES];
And can be stop music as
[[SoundManager sharedManager] stopMusic];
Complete Documentation is on GitHub
First import this framework to your file
#import <AVFoundation/AVFoundation.h>
Then declare an instance of AVAudioPlayer.
AVAudioPlayer *audioPlayer;
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"Name of your audio file"
ofType:#"type of your audio file example: mp3"];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
audioPlayer.numberOfLoops = -1;
[audioPlayer play];
To play your bundle audio file using below code if you generate the system sound ID
for(int i = 0 ;i< 5;i++)
{
SystemSoundID soundFileObject;
NSString *audioFileName = [NSString stringWithFormat:#"Alarm%d",i+1];
NSURL *tapSound = [[NSBundle mainBundle] URLForResource: audioFileName
withExtension: #"caf"];
// Store the URL as a CFURLRef instance
CFURLRef soundFileURLRef = (__bridge CFURLRef) tapSound;
// Create a system sound object representing the sound file.
AudioServicesCreateSystemSoundID (
soundFileURLRef,
&soundFileObject
);
[alarmToneIdList addObject:[NSNumber numberWithUnsignedLong:soundFileObject]];
}
You can play the sound by using below code
AudioServicesPlaySystemSound([[alarmToneIdList objectAtIndex:row]unsignedLongValue]);
To achieve this below framework need to add in your Xcode
AudioToolbox
Finally below header files are needs to be import in controller
#import AudioToolbox/AudioToolbox.h
#import AudioToolbox/AudioServices.h
Updated for Swift 4
Playing from main bundle
- iOS 11 only
import AVFoundation
var player: AVAudioPlayer?
The following code loads the sound file and plays it, returning an error if necessary.
guard let url = Bundle.main.url(forResource: "test", withExtension: "m4a") else { return }
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try AVAudioSession.sharedInstance().setActive(true)
guard let player = player else { return }
player.play()
} catch let error {
// Prints a readable error
print(error.localizedDescription)
}
Swift 4.2
var soundFilePath = "\(Bundle.main.resourcePath ?? "")/test.m4a"
var soundFileURL = URL(fileURLWithPath: soundFilePath)
var player = try? AVAudioPlayer(contentsOf: soundFileURL)
player?.numberOfLoops = -1 //Infinite
player?.play()
I'm making an app that downloads movies from the server and stores them localy in the NSDocumentDirectory.
This works fine.
I want to add a thumbnail generated from each movie in front of the name in each cell.
My problem:
How can I generate a thumbnail from a movie after it is downloaded (so instantly, without having to play the movie first)? I want to store the thumbnails with the same name of the movie as a jpg in the NSDocumentDirectory.
My guess
-download movie and store it in NSDocumentDirectory (works)
-somehow load the movie in the MPMoviePlayerController's memory (don't know how)
-when loaded in memory, generate thumbnail with thumbnailImageAtTime (MPMovieTimeOptionNearestKeyFrame) (should work)
-store it (should work)
If anyone could help me...
Thanks
#import <MediaPlayer/MediaPlayer.h>
-(UIImage*)getFirstFrameFromVideoFile:(NSString*)sourceFilePath {
NSURL *videoURL = [NSURL fileURLWithPath:sourceFilePath];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
UIImage *thumbnail = [player thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame];
//Player autoplays audio on init
[player stop];
[player release];
return thumbnail;
}
Other tasks you know already.
Yes, using MPMoviePlayer works... but you must be sure that you do not have another movie player playing elsewhere in your app (even the UIWebView plug-in...) or you will get in trouble.
I do this way:
UIImage *thumbnail = nil;
NSURL *url = [NSURL fileURLWithPath:pathname];
AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:url options:nil];
AVAssetImageGenerator *generator = [[AVAssetImageGenerator alloc] initWithAsset:asset];
generator.appliesPreferredTrackTransform = YES;
NSError *error = nil;
CMTime time = CMTimeMake(3, 1); // 3/1 = 3 second(s)
CGImageRef imgRef = [generator copyCGImageAtTime:time actualTime:nil error:&error];
if (error != nil)
NSLog(#"%#: %#", self, error);
thumbnail = [[UIImage alloc] initWithCGImage:imgRef];
CGImageRelease(imgRef);
Hope this might help
This is the code I use which should generate the thumbnail
(added a big uiimageview for testing, works when I load a local image in it)
NSString *path;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
path = [[paths objectAtIndex:0] stringByAppendingPathComponent:#"snijtechniekendir/videos"];
path = [path stringByAppendingPathComponent:[videos objectAtIndex:indexPath.row]];
NSURL *videoURL = [NSURL fileURLWithPath:path];
NSLog(#"video url: %#", videoURL);
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
UIImage *thumbnail = [player thumbnailImageAtTime:1 timeOption:MPMovieTimeOptionNearestKeyFrame];
UIImageView *cellimage = [[UIImageView alloc] initWithFrame:CGRectMake(2, 2 , 400, 400)];
[cell.contentView addSubview:cellimage];
NSData *imgData = UIImagePNGRepresentation(thumbnail);
NSLog(#"lenght of video thumb: %#", [imgData length]);
[self.view addSubview:cellimage];
[cellimage setImage:thumbnail];
This is the log for one video file
