Unable to play mp4 videos in AVPlayer - objective-c

I'm using AVPlayer to play videos. I couldn't play .mp4 videos.I'm getting this black screen. here is my code.
`NSString *filePath = [self.videoArray objectAtIndex:index];
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:filePath ofType: #"mp4];
url = [[NSURL alloc] initFileURLWithPath: soundFilePath];
playerViewController = [[AVPlayerViewController alloc] init];
playerViewController.videoGravity = AVLayerVideoGravityResize;
playerViewController.view.frame = self.view.bounds;
playerViewController.showsPlaybackControls = NO;
video=[AVPlayer playerWithURL:url];
playerViewController.player = _video;
playerViewController.view.userInteractionEnabled = false;
[video play];
[self.view addSubview:playerViewController.view];`

Try this code I think it would be working for you, because It seems your URL is not for bundle its from web.
// your filepath which is may be "http" type
NSString *filePath = [self.video_Array objectAtIndex:index];
// http to NSURL using string filepath
NSURL *url= [[NSURL alloc] initWithString:filePath];
AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc] init];
playerViewController.videoGravity = AVLayerVideoGravityResize;
playerViewController.view.frame = self.view.bounds;
playerViewController.showsPlaybackControls = NO;
video=[AVPlayer playerWithURL:url];
playerViewController.player = _video;
playerViewController.view.userInteractionEnabled = false;
[video play];
[self.view addSubview:playerViewController.view];

ObjC Unit test allowsExternalPlayback

I have an AVPlayer where I want to check if allowsExternalPlayBack is set to false. So in my code I have something like
NSURL *url = [NSURL URLWithString:#"https://www.apple.com"];
AVPlayerItem *item = [[AVPlayerItem alloc] initWithURL:url];
AVPlayer *player = [AVPlayer playerWithPlayerItem:item];
player.allowsExternalPlayback = NO;
When I try to test this in a unit test, even in following code, This does not work.
NSURL *url = [NSURL URLWithString:#"https://www.apple.com"];
AVPlayerItem *item = [[AVPlayerItem alloc] initWithURL:url];
AVPlayer *player = [AVPlayer playerWithPlayerItem:item];
player.allowsExternalPlayback = NO;
XCTAssertFalse(player.allowsExternalPlayback);
Result: allowsExternalPlayback is still YES
Expected result: allowsExternalPlayback is NO (at the point of assertion)

How do I play a video from Cloudkit on tvOS?

I have a problem i have been trying to solve for a day and i tired of beating my head aaginst the wall. Anyone know how to do this?
Number 1 Works Great
Works Great
- (void) viewDidLoad {
[super viewDidLoad];
NSURL *url = [NSURL URLWithString:#"http://techslides.com/demos/sample-videos/small.mp4"];
AVPlayer *avPlayer = [[AVPlayer alloc] initWithURL:url];
self.player = avPlayer;
[self.player play];
}
Does not work
- (void) viewDidLoad {
[super viewDidLoad];
CKAsset *asset = record[#"VideoFile"];
AVPlayer *avPlayer = [[AVPlayer alloc] initWithURL:asset.fileURL];
self.player = avPlayer;
[self.player play];
}
Does not work
- (void) viewDidLoad {
[super viewDidLoad];
CKAsset *asset = record[#"VideoFile"];
NSString *fileName = record[#"videoFileKey"];
NSData *data = [NSData dataWithContentsOfURL:asset.fileURL];
NSString *cachesDirectoryPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *path = [cachesDirectoryPath stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.mp4", fileName]];
[data writeToFile:path atomically:YES];
if ([[NSFileManager defaultManager] fileExistsAtPath:path]) {
NSURL *url = [NSURL URLWithString:path];
AVPlayer *avPlayer = [[AVPlayer alloc] initWithURL:url];
self.player = avPlayer;
[self.player play];

Play sound when app is in background or screen is locked

I have a timer that plays a sound when time reaches 0, but now I can't understand how to fire the event in order to play the sound if the app is in background mode or the screen is locked, What I found searching on the web was to set "UIBackgroundModes" in my .plist file, and add "audio" as array member.
UIBackgroundModes Array
Item0 String audio
Then add in the app delegate the following code:
NSError *setCategoryErr = nil;
NSError *activationErr = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:&setCategoryErr];
[[AVAudioSession sharedInstance] setActive:YES error:&activationErr];
But the sound doesn't get played.. So I was wondering if it's possible to do something like this or I should change method
EDIT:
I imported:
#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>
And this is the code I use to create the sound:
AVAudioPlayer *player;
NSString *soundFilePath = [NSString stringWithFormat:#"%#/clock.mp3",
[[NSBundle mainBundle] resourcePath]];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL
error:nil];
player.numberOfLoops = -1;
dispatch_async(dispatch_get_main_queue(), ^{
[player prepareToPlay];
});
Then to play it:
[player play];
I have just a snippet of Swift code but it should be easy to convert it to Obj-C
Try to use AVPlayerItem init with URL and then set AVPlayer init with PlayerItem
let assetUrl = self.nowPlayingItem!.associatedItem!.valueForProperty(MPMediaItemPropertyAssetURL) as! NSURL
let playerItem = AVPlayerItem(URL: assetUrl)
if let player = self.player {
player.replaceCurrentItemWithPlayerItem(playerItem)
} else {
self.player = AVPlayer(playerItem: playerItem)
}
self.player!.play()
and for this line of code:
NSString *soundFilePath = [NSString stringWithFormat:#"%#/clock.mp3",
[[NSBundle mainBundle] resourcePath]];
Have you tried:
[[NSBundle mainBundle] URLForResource:#"song" withExtension:#"mp3"];
// Create a new player item
NSURL *assetUrl = [nowPlayingItem valueForProperty:MPMediaItemPropertyAssetURL];
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:assetUrl];
// Either create a player or replace it
if (self.player) {
[self.player replaceCurrentItemWithPlayerItem:playerItem];
} else {
self.player = [AVPlayer playerWithPlayerItem:playerItem];
}
nowPlayingItem is here a MPMediaItem but just replace NSURL *assetUrl = [nowPlayingItem valueForProperty:MPMediaItemPropertyAssetURL]; by NSURL *assetUrl =[[NSBundle mainBundle] URLForResource:#"song" withExtension:#"mp3"];

AVPlayer not playing video

- (void)viewDidLoad{
[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:#"VidName" ofType:#"mov"];
NSURL *url = [NSURL URLWithString:path];
AVPlayer *av = [[AVPlayer alloc] initWithURL:url];
AVPlayerLayer *layer = [AVPlayerLayer playerLayerWithPlayer:av];
[layer setFrame:self.view.frame];
[self.view.layer addSublayer:layer];
[av play];
NSLog(#"error: %#", av.error);
}
The error being logged is NULL.
instead of
NSURL *url = [NSURL URLWithString:path];
use following line.
NSURL *url=[[NSURL alloc]initFileURLWithPath:path];

MPMoviePlayerController generate thumbnail of local video file and store it

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
