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)

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];
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];
}
}
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"];
- (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];
I'm normally able to work out why sigabrts happen, but i'm totally stuck on this one.. I'm launching the app from a remote notification, which all works fine until it gets to this bit of code:
NKIssue *issueNK = [[NKLibrary sharedLibrary] issueWithName:[issueId stringValue]];
if (issueNK == nil) {
issueNK = [[NKLibrary sharedLibrary] addIssueWithName:[issueId stringValue] date:[NSDate date]];
}
NSMutableDictionary* settings = [[[NSMutableDictionary alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"Settings" ofType:#"plist"]] autorelease];
NSURL *downloadURL = [NSURL URLWithString:
[NSString stringWithFormat:[settings objectForKey:#"IssueBundleUrl"], [issue.issueId intValue]]];
NSURLRequest *request = [NSURLRequest requestWithURL:downloadURL];
NKAssetDownload *assetDownload = [issueNK addAssetWithRequest:request]; //sigabrt on this line
[assetDownload downloadWithDelegate:issueListViewController];
in the debugger, issueNK and request both seem to be fine, not nil or anything.
any ideas? thanks.
I would guess that the only reason you would see an exception on that line, is if the issue has already been downloaded or is being downloaded. So you need to check the status of your issue first:
NKIssue *issueNK = [[NKLibrary sharedLibrary] issueWithName:[issueId stringValue]];
if (issueNK == nil) {
issueNK = [[NKLibrary sharedLibrary] addIssueWithName:[issueId stringValue] date:[NSDate date]];
}
if ([issueNK status] != NKIssueContentStatusNone)
return;
NSMutableDictionary* settings = [[[NSMutableDictionary alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"Settings" ofType:#"plist"]] autorelease];
NSURL *downloadURL = [NSURL URLWithString:
[NSString stringWithFormat:[settings objectForKey:#"IssueBundleUrl"], [issue.issueId intValue]]];
NSURLRequest *request = [NSURLRequest requestWithURL:downloadURL];
NKAssetDownload *assetDownload = [issueNK addAssetWithRequest:request];
[assetDownload downloadWithDelegate:issueListViewController];
