I am trying to insert an AVURLAsset of a AVPlayerItem that states AVPlayerItemStatusReadyToPlay into an AVMutableComposition like this: composition_ = [[AVMutableComposition alloc] init]; insertionPoint_ = kCMTimeZero; item_ = [[AVPlayerItem playerItemWithURL:[NSURL URLWithString:@"http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8"]] retain]; [item_ addObserver:self forKeyPath:@"status" options:0 context:nil]; player_ = [[AVPlayer playerWithPlayerItem:item_] retain]; [player_ addObserver:self forKeyPath:@"currentItem.duration" options:0 context:nil]; /** * append a player-item to

I'm trying to copy Apple's behavior in video playback that allows the user to stretch the video image to fill the bounds. @interface FHVideoPlayerView : UIView @end @interface FHVideoPlayerView + (Class)layerClass { return [AVPlayerLayer class]; } - (void)setAspectMode:(FHVideoPlayerAspectMode)aspectMode animated:(BOOL)animated { FHVideoPlayerAspectMode current = [self aspectMode]; FHVideoPlayerAspectMode final = aspectMode; NSString *fromValue; NSString *toValue; AVPlayerLayer *layer = (AVPlayerLayer *)[self layer]; switch (current) { case FHVideoPlayerAspectFill: fromValue =

I want to trim a video: -(void)trimVideo:(NSURL*)outputURL { //[[NSFileManager defaultManager] removeItemAtURL:outputURL error:nil]; AVURLAsset *asset = [AVURLAsset URLAssetWithURL:outputURL options:nil]; AVAssetExportSession *exportSession = [[AVAssetExportSession alloc] initWithAsset:asset presetName:AVAssetExportPresetLowQuality]; NSString * outputFilePath = NSHomeDirectory(); outputFilePath = [outputFilePath stringByAppendingPathComponent:@"Library"]; outputFilePath = [outputFilePath stringByAppendingPathComponent:@"temp.mov"]; NSURL * outputFileUrl = [NSURL fileURLWithPath:outputFilePath]

I'm using AVFoundation to put a watermark in my movies. This works well with the code that's been going around on the internet and Apple. But I don't want to show the watermark the complete time and I want to show different watermarks in the same movie. I've an AVAsset: NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"MOV"]; NSURL *url = [[NSURL alloc] initFileURLWithPath: path]; avasset_camera = [AVAsset assetWithURL:url]; An AVMutableComposition: AVMutableComposition *mix = [AVMutableComposition composition]; The UIImage converted to a CALayer and than added to

Something really strange is happening, I am trying to capture an image using AVFoundation, the Camera roll image seems just fine, but the image preview has the image rotated by 90 degrees. This is the code I am using to capture an image AVCaptureConnection *videoConnection = nil; for (AVCaptureConnection *connection in stillImageOutput.connections) { for (AVCaptureInputPort *port in [connection inputPorts]) { if ([[port mediaType] isEqual:AVMediaTypeVideo] ) { videoConnection = connection; break; } } if (videoConnection) { break; } } //NSLog(@"about to request a capture from: %@",
