avvideocomposition

AVFoundation allows you to "compose" 2 assets (2 videos) as 2 "tracks", just like in Final Cut Pro, for example. The theory says I can have 2 videos on top of each other, with alpha, and see both. Either I'm doing something wrong, or there's a bug somewhere, because the following test code, although a bit messy, clearly states I should see 2 videos, and I only see one, as seen here: http://lockerz.com/s/172403384 -- the "blue" square is IMG_1388.m4v For whatever reason, IMG_1383.MOV is never shown. NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:YES]

After applying an AVVideoComposition to my AVPlayerItem , the filter I apply does work, but the video gets rotated in the AVPlayerLayer . I know for a fact that the problem is not with the filtered frame because if I show the frame in a UIImageView , the frame is rendered 100% correctly. The video shows correctly until I apply a videoComposition . Setting the videoGravity on the AVPlayerLayer does not help. The video gets rotated 90º clockwise and gets stretched in the layer. Essentially, the video is displayed perfectly in the AVPlayerLayer before the AVPlayerItem is fed through the

I need a simple thing: play a video while rotating and applying CIFilter on it. First, I create the player item: AVPlayerItem *item = [AVPlayerItem playerItemWithURL:videoURL]; // DEBUG LOGGING AVAssetTrack *track = [[item.asset tracksWithMediaType:AVMediaTypeVideo] objectAtIndex:0]; NSLog(@"Natural size is: %@", NSStringFromCGSize(track.naturalSize)); NSLog(@"Preffered track transform is: %@", NSStringFromCGAffineTransform(track.preferredTransform)); NSLog(@"Preffered asset transform is: %@", NSStringFromCGAffineTransform(item.asset.preferredTransform)); Then I need to apply the video

This code used to work on iOS9 to add a watermark and text to a video but since iOS10 it's not working anymore. There is a iOS 10 bug that has been filed but no answer from Apple. I have not been able to implement any workaround to add watermark and text on video. With this code some times the video will be exported successfully but most of time it won't be exported. How should I use AVVideoCompositionCoreAnimationTool so that it works as it did on iOS9. let videoComposition: AVMutableVideoComposition = AVMutableVideoComposition() videoComposition.frameDuration = CMTimeMake(1, 60)

I know you could merge multiple clips and create a single video by appending one after other using AVFoundation classes- AVURLAsset, AVMutableComposition, AVMutableCompositionTrack etc. There are apps like 'Video-Joiner' that do that. What I want to do is to juxtaposition 2 videos. My app idea - SelfInterviewer please don't steal :) First I record video 1 using front facing camera standing left to the frame. Then video 2 standing to the right. In video 1 ask a question and in video 2 I answer. When I merge, it should appear like I am being interviewed by myself. I am almost sure its not
