问题 I am working on an app which is intended to play life radio by using TuneIn URLs. In TuneIn, there is an http get request in the API which provides a JSON with all the URL and its bitrates. So http://opml.radiotime.com/Tune.ashx?id=s150147&formats=aac,mp3&render=json will return { "head": { "status": "200"}, "body": [ { "element" : "audio", "url": "http://player.absoluteradio.co.uk/tunein.php?i=a664.aac", "reliability": 95, "bitrate": 64, "media_type": "aac", "position": 0, "player_width":

问题 How do you play a streaming video with AVPlayer ? import Cocoa import AVKit class StreamViewController: NSViewController { var videoPlayer: AVPlayer! @IBOutlet weak var moviePlayerView: AVPlayerView! override func viewDidLoad() { super.viewDidLoad() } override func viewWillAppear() { super.viewWillAppear() } override func viewDidAppear() { super.viewDidAppear() openStream() } func openStream() { completeOpenStream { (done) -> (Void) in if done { print("done!") } } } func completeOpenStream

问题 Here is nice simple avplayer piece of code playing a small collection of videos in a queue. My question. I actually want to pause between videos on my queue. Is it possible? I did note that rate fires twice; status fires just once as does notification. import UIKit import AVKit import AVFoundation class ViewController: UIViewController { @IBOutlet weak var VideoView: UIView! var player:AVQueuePlayer = AVQueuePlayer() @IBAction func NextSlide(sender: AnyObject) { player.play() } override func

问题 We have videos encoded via bitmovin.com and provided as HTTP Live Streams (Fairplay HLS), but subtitles although in WebVTT format are exposed separately as direct URLs for the whole file, not individual segments and are not part of the HLS m3u8 playlist. I am looking for the way how an external .vtt file downloaded separately can still be included in the HLS stream and be available as a subtitle in AVPlayer. I know Apple's recommendation is to include segmented VTT subtitles into the HLS

问题 I am building an app in Swift on Xcode 7.2 I added a video to my ViewController. Here's the code: import UIKit import AVKit import AVFoundation class GymViewController: UIViewController { var playerViewController = AVPlayerViewController() var playerView = AVPlayer() let fileFemaleURL = NSURL(fileURLWithPath:"/Users/marienkoen/Documents/AppDevelopment/ROZsport/ROZsport/GymFemale-2434.m4v") override func viewDidLoad() { super.viewDidLoad() } @IBAction func playButtonPressed(sender: AnyObject)

问题 My question is, I am using the function below, to compose a video and audio. I want to keep video's original sound but it goes away somehow, I do not have any clue. I got this function from this answer I tried to change volumes right after appending AVMutableCompositionTrack s but it did not work For instance; mutableVideoCompositionTrack.prefferedVolume = 1.0 mutableAudioCompositionTrack.prefferedVolume = 0.05 But still, all you can hear is only the audio file. The function; private func

问题 I am trying to get AVPlayer to play a m3u8 playlist that is a local file. I have narrowed this down to a simple test case using one of Apple's sample playlists: https://tungsten.aaplimg.com/VOD/bipbop_adv_fmp4_example/master.m3u8 If i play this playlist from the remote url, AVPlayer plays this fine. However, if i download this playlist to a local file, and then hand AVPlayer the local file URL, AVPlayer will not play it. It just shows the crossed out play symbol. Interestingly enough, this

问题 I'm implementing AVAssetExportSession to trim a video online but always returns failed. Here is my implementation: NSString *url = @"http://www.ebookfrenzy.com/ios_book/movie/movie.mov"; NSURL *fileURL = [NSURL URLWithString:url]; AVAsset *asset = [AVAsset assetWithURL:fileURL]; AVAssetExportSession *exportSession = [[AVAssetExportSession alloc] initWithAsset:asset presetName:AVAssetExportPresetHighestQuality]; NSURL *exportUrl = [NSURL fileURLWithPath:[documentsDirectory

问题 I have a videoPlayer with controls. These are not visible with iOS11 + no problem up to iOS10 This is a demo with the iPhone8 simulator iPhone 8 Demo This is a demo with the iPhoneX simulator. The controls aren't showing at the bottom of the player iPhone X Demo I believe this has a lot to do with the new safe area. We are using contentOffset (below) to offset from the top. Changing the value makes no difference. No controls visible This is the code below I am using to configure the player :

问题 So my app has gone from being a single view to being a navigation controller view + tab bar controller view. Now in my single app view controller I had all this code. // // ViewController.swift // DRN1 // // Created by Russell Harrower on 24/11/19. // Copyright © 2019 Russell Harrower.
