问题 I'm trying to use AVPlayer with custom URL loading (a custom NSURLProtocol subclass). But it seems [NSURLProtocol registerClass] does not work with AVPlayer in real device (see this thread). Now I'm trying to use AVAssetResourceLoaderDelegate to do the custom URL loading. However it is a bit confusing to me how the delegate will be triggered. The URL I deal with looks like this https://some_ip_address:port/resource/ , but it seems like my delegate is not called for such URL. I tried to change

问题 I have an app that plays back videos. It's compatible with iOS 11, 12 and iOS 13. On iOS 11 and 12, video playback works properly as expected using either AVPlayerViewController or even just AVPlayerLayer . However, on iOS 13 I started getting reports that suddenly video wasn't loading (or would only load audio, or only the first frame) for quite a few users when they updated iOS. I had a really hard time replicating it, but some mentioned it occurred mostly with poor network connections, and

问题 this should be a simple one. I have an AVPlayer playing a video file and I want to be able to jump to a specific time but I'm having some trouble understanding how CMTime works. I need to specify the time in seconds. For example: if I wanted to jump to second 10.8 I'd like to do something like this: [self.avPlayer.currentItem seekToTime:CMTimeMakeWithSeconds(10.8, 1]; But I'm not getting the result I want. 回答1: http://warrenmoore.net/understanding-cmtime Might give you a clearer idea of

问题 In my new SwiftUI project I have an AVPlayer for streaming music from url. Now I need to control the current time of playing track and the volume through sliders, here is the part of design: now I can control the player with UserData final class and its @Published vars, like isPlaying : final class UserData: ObservableObject { // ... @Published var player: AVPlayer? = nil @Published var isPlaying: Bool = false //... func playPausePlayer(withSong song: Song, forPlaylist playlist: [Song]?) { //

问题 I'm having a problem which I haven't seen a post like it on here. I have an AVPlayerViewController which plays a video based off the path from my Firebase Database (not Storage). The video plays perfectly as I want it to, but only once I watch a video that is clicked on in the UIImagePickerController elsewhere in the app. So for example, the AVPlayer will show a black background (this occurs with all of the AVPlayer's in the app), except for when I watch a video from the
