I download a mp4 file into the date folder. I am able to run an AVPlayer and view the video in the app. After some time video won't play. If I enable UIFileSharingEnabled and check if file exists, I can see it's there but then it won't play even from accessing it through Files. If I copy the file from iOS to Mac then I can pay the video on Mac, but not anymore on iOS. If I delete the app, install again and download the video while UIFileSharingEnabled and if it's played in the app it can be played in the Files app, but again after some time it's not playable again... I can see only first frame. I can even see the length of video. It happens to multiple videos. Any clues?

I'm working on a custom spatial video player that uses AVSampleBufferDisplayLayer as render layer. When I feed it with CMSampleBuffer that output from VTCompressionSession using new encoding API it can display normally but I don't know if it can work in VisionPro. Anyone has idea?

Loading a video that played on tvOS 17, won't now play in tvOS 17.2. It isn't true for all videos or even all videos of a certain type. This code works fine on tvOS 17, but not on 17.2 import SwiftUI import AVKit struct ContentView: View { var body: some View { let player = AVPlayer(url: URL(string: "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4")!) VideoPlayer(player: player) .onAppear { player.play() } } } I have tried reloading the metadata. I tried making the player from an AVAsset rather than a URL. I can't seem to see what is making it work with some videos and not all and what is different from tvOS 17 to 17.2.

Hi Team, We see an issue with this version if CoreMedia requesting multiple qualities at all times for a stream. We don't see this issue on 1.0.0.21C62. We are unsure what would be causing this.

The following type of problem has appeared. I need to flip through the video. Imagine you have, say, 3 videos, and you can scroll through them and choose which video you want to watch. For this, I decided to use a TabView with the .page style. But it turned out that it didn't work. And I found myself in a stupor. The TabView itself starts to lag, the scrolling starts to lag, the videos do not start the first time, and sometimes the control panel does not even appear on some videos, which is why it is impossible to expand the video to full screen. The code will be below, maybe someone has encountered this problem, how did he solve it, maybe there are some other options to make a similar logic? let videos: [String] = ["burpee", "squat", "step-up", "sun-salute"] var body: some View { TabView { ForEach(videos, id: \.self) { videoName in VideoPlayerView(videoName: videoName) .clipShape(RoundedRectangle(cornerRadius: 25)) } } .frame(width: 375, height: 230) } struct VideoPlayerView: View { let videoName: String var body: some View { if let videoURL = Bundle.main.url(forResource: videoName, withExtension: "mp4") { VideoPlayerWrapper(player: AVPlayer(url: videoURL)) } else { Text("No Video \(videoName)") } } } #Preview { VideoPlayerView(videoName: "squat") } struct VideoPlayerWrapper: UIViewControllerRepresentable { let player: AVPlayer func makeUIViewController(context: Context) -> AVPlayerViewController { let controller = AVPlayerViewController() controller.player = player controller.showsPlaybackControls = true return controller } func updateUIViewController(_ uiViewController: AVPlayerViewController, context: Context) {} }

I'm creating an app with a video player streaming video from an URL. The AVPlayer only takes the URL address of the video but I'd like to create a custom URLRequest and then use that to stream the video from online. So current situation is this: let videourl = URL(string: "videofoobar.com") let player = AVPlayer(url: videourl) player.play() And I would like to go to something like this: let videourl = URL(string: "videofoobar.com") var request = URLRequest(url: videourl) let player = AVPlayer(request: request) //This obviously fails, any workaround? player.play() I know it is not possible to do it like this as AVPlayer only takes URL or AVPlayerItem as parameter. Is there any workaround to make URLRequest and then give it to AVPlayer for online streaming?

I’ve got some code that creates an AVPlayerItem from a URL, the creates an AVQueuePlayer from it. If I check the player item's status after that, it's still unknown. According to the docs, it'll remain unknown until it is associated with an AVPlayer, and then it "immediately begins enqueuing the item’s media and preparing it for playback." But checking the status right after that, I still get unknown, which tells me it’s not quite immediate. Is there any way to test if the player item will work immediately after creation? In this case, the problem is that my app doesn't have permission, due to it being a bookmark saved in a sandboxed app.

In my SwiftUI/SwiftData application, I want to store videos in SwiftData objects (using external storage). To display them, I need to instantiate an AVPlayer (for use in a VideoPlayer view). But AVPlayer expects a URL, not a Data object. Obviously, I can solve this problem via a file-caching scheme (i.e., by creating a local file when needed, using an LRU cache to control it's lifetime), but this results in an extra copy of the data (besides the hidden local file managed by SwiftData/CoreData). However, since videos can be quite large, I would prefer not to do that. Has anyone any thoughts about how I can avoid the extra data copy?

Is there a way to play a specific rectangular region of interest of a video in an arbitrarily-sized view? Let's say I have a 1080p video but I'm only interested in a sub-region of the full frame. Is there a way to specify a source rect to be displayed in an arbitrary view (SwiftUI view, ideally), and have it play that in real time, without having to pre-render the cropped region? Update: I may have found a solution here: img DOT ly/blog/trim-and-crop-video-in-swift/ (Apple won't allow that URL for some dumb reason)

Hi, I'm trying to play multiple video/audio file with AVPlayer using AVMutableComposition. Each video/audio file can process simultaneously so I set each video/audio in individual tracks. I use only local file. let second = CMTime(seconds: 1, preferredTimescale: 1000) let duration = CMTimeRange(start: .zero, duration: second) var currentTime = CMTime.zero for _ in 0...4 { let mutableTrack = composition.addMutableTrack( withMediaType: .audio, preferredTrackID: kCMPersistentTrackID_Invalid ) try mutableTrack?.insertTimeRange( duration, of: audioAssetTrack, at: currentTime ) currentTime = currentTime + second } When I set many audio tracks (maybe more than 5), the first part sounds a little different from original when it starts. It seems like audio's front part is skipped. But when I set only two tracks, AVPlayer plays as same as original file. avPlayer.play() How can I fix it? Why do audio tracks affect that don't have any playing parts when start? Please let me know.

Hi, I've started learning swiftUI a few months ago, and now I'm trying to build my first app :) I am trying to display VTT subtitles from an external URL into a streaming video using AVPlayer and AVMutableComposition. I have been trying for a few days, checking online and on Apple's documentation, but I can't manage to make it work. So far, I managed to display the subtitles, but there is no video or audio playing... Could someone help?

When attempting to present an AVPlayerViewController without animations, the video orientation does not function as expected. However, when the animation parameter is set to true, the video orientation works correctly. The following code does not produce the desired video orientation behavior when animation is disabled: parentViewController.present(playerViewController, animated: false) In contrast, the desired video orientation is achieved with animation enabled: parentViewController.present(playerViewController, animated: true)

How can be changed playback (forward and backward) buttons values in AVPictureInPictureController? My backward and forward buttons have 15 seconds value by default (screenshot from my app is attached), but I've found other apps has 10 seconds (for instance, Apple TV iOS app). This Apple forum discussion I've read that AVPlayerViewController adapts its capabilities and controls to the asset being played. But it seems backward/forward values in PiP stay the same for all videos independent of duration in both my app and apps I've found. But I can't find the way to change them.

Hi, We were using Capture Systems of AVKit to take photo's in our app and we need to zoom camera to certain limit. If we configure zoomFactor to AVCaptureDevice we receiving awkward VideoFrames(blurred images) through Camera. Our app works fine in all devices of iPhone/iPad except devices that support Center Stage. We looked into Apple's default Camera app we understood that it was implemented using UIImagePickerController. We tried with multiple combinations of AVCaptureDevice.Format/AVCaptureSession.Preset but nothing helped us. We want's to achieve zoom(front camera) through AVKit, we'll add code snippet we used below please help on this. session.sessionPreset = AVCaptureSession.Preset.photo var bestFormat: AVCaptureDevice.Format? var bestFrameRateRange: AVFrameRateRange? for format in device.formats { for range in format.videoSupportedFrameRateRanges { if range.maxFrameRate > bestFrameRateRange?.maxFrameRate ?? 0 { bestFormat = format bestFrameRateRange = range } } } if let bestFormat = bestFormat, let bestFrameRateRange = bestFrameRateRange { do { try device.lockForConfiguration() // Set the device's active format. device.activeFormat = bestFormat // Set the device's min/max frame duration. let duration = bestFrameRateRange.minFrameDuration device.activeVideoMinFrameDuration = duration device.activeVideoMaxFrameDuration = duration device.videoZoomFactor = 2.0 device.unlockForConfiguration() } catch { // Handle error. } }

Hey Apple! I'm just wondering if there are any recommendations on best practices for supporting AV experiences in SwiftUI? As far as I know, VideoPlayer is the only API available directly supported in SwiftUI in AVKit (https://developer.apple.com/documentation/avkit) without the need for UIViewRepresentable / UIViewControllerRepresentable bridging of AVPlayer into SwiftUI. However there are many core video and audio experiences that a modern audience expect that are not supported in VideoPlayer. e.g. PiP Is there a roadmap for support in SwiftUI directly? Thanks!
