Example Hi, Struggling to rotate this video to show in the proper orientation and fill the entire screen. I cannot get the avasset with videocompisition but cannot get it to work correctly. let videoAsset: AVAsset = AVAsset(URL: outputFileURL) as AVAsset let clipVideoTrack = videoAsset.tracksWithMediaType(AVMediaTypeVideo).first! as AVAssetTrack let newHeight = CGFloat(clipVideoTrack.naturalSize.height/3*4) let composition = AVMutableComposition() composition.addMutableTrackWithMediaType(AVMediaTypeVideo, preferredTrackID: CMPersistentTrackID()) let videoComposition = AVMutableVideoComposition

We want to allow the user to place animated "stickers" over video that they record in the app and are considering different ways to composite these stickers. Create a video in code from the frame-based animated stickers (which can be rotated, and have translations applied to them) using AVAssetWriter . The problem is that AVAssetWriter only writes to a file and doesn't keep transparency. This would prevent us from being able to overly it over the video using AVMutableComposition . Create .mov files ahead of time for our frame based stickers and composite them using AVMutableComposition and

I've been struggling with adding assets from the iPhone Photo Library to a AVMutableComposition and then export them. Here is what I got: Finding the assets: (here I grab the AVURLAsset) -(void) findAssets { ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init]; // Enumerate just the photos and videos group by using ALAssetsGroupSavedPhotos. [library enumerateGroupsWithTypes:ALAssetsGroupSavedPhotos usingBlock:^(ALAssetsGroup *group, BOOL *stop) { // Within the group enumeration block, filter to enumerate just videos. [group setAssetsFilter:[ALAssetsFilter allVideos]]; [group

I'm using the below code snipped while merging videos with original audio. It has been working until I upgraded to iOS9. Anyone faced the same issue and any help to resolve would be greatly appreciated. I couldn't find anything after researching whole day. AVAssetTrack *videoTrack = nil; AVAssetTrack *audioTrack = nil; CMTime insertionPoint = kCMTimeZero; if([[url tracksWithMediaType:AVMediaTypeVideo] count] != 0) { videoTrack = [url tracksWithMediaType:AVMediaTypeVideo][0]; } if([[url tracksWithMediaType:AVMediaTypeAudio] count] != 0) { audioTrack = [url tracksWithMediaType:AVMediaTypeAudio]

I'm trying to capture the screen while doing a video preview with AVFoundation (AVCaptureDeviceInput and AVCaptureVideoDataOutput) Initiate preview: func startCamera(){ var screenSize = UIScreen.mainScreen().bounds.size; self.previewView = UIView(frame: CGRectMake(0, 0, UIScreen.mainScreen().bounds.size.width, UIScreen.mainScreen().bounds.size.height)); self.previewView.contentMode = UIViewContentMode.ScaleAspectFit self.view.addSubview(previewView); session.sessionPreset = AVCaptureSessionPresetHigh let devices = AVCaptureDevice.devices(); // Loop through all the capture devices on this phone

I am planning to build an NSOpenGLView for an OS X app using SWIFT which can be used to apply Core Image Filter and effects to a video, so far I have worked on the code for the video Controller to add video playback, but I am not sure how to apply the filter to the video: class VideoMediaViewController: NSViewController { weak var mainView : DTMainViewController? @IBOutlet weak var aVPlayerView: AVPlayerView! var url:NSURL?{ didSet{ // this is the setter } } var observer:AnyObject? var player:AVPlayer? var videoOutput:AVPlayerItemVideoOutput? var ciContext:CIContext? var loadStatus:NSNumber?
