Avplayer Resuming After Incoming Call

Resuming AVPlayer after phone call

I solved this but creating a shared VideoPlayer class that contained references to all the screen that had animations.

import Foundation
import UIKit
import AVKit

    class VideoPlayer: NSObject {

        static var shared: VideoPlayer = VideoPlayer()

        var avPlayer: AVPlayer!
        var avPlayerLayer: AVPlayerLayer!

        weak var vcForConnect:ConnectVC?
        weak var vcForList:ListVC?

        override init() {
            super.init()
            guard let path = Bundle.main.path(forResource: "animation", ofType:"mp4") else {
                print("video not found")
                return
            }
            avPlayer = AVPlayer(url: URL(fileURLWithPath: path))
            avPlayerLayer = AVPlayerLayer(player: avPlayer)
            avPlayerLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill
            avPlayer.volume = 0
            avPlayer.actionAtItemEnd = .none
            loopVideo(videoPlayer: avPlayer)
            avPlayer.play()
            NotificationCenter.default.addObserver(self, selector: #selector(handleInterruption(notification:)), name: AVAudioSession.interruptionNotification, object: nil)

        }

        deinit {
            avPlayer.pause()
        }

        @objc func handleInterruption(notification: Notification) {
            guard let info = notification.userInfo,
                let typeValue = info[AVAudioSessionInterruptionTypeKey] as? UInt,
                let type = AVAudioSession.InterruptionType(rawValue: typeValue) else {
                    return
            }
            if type == .began {
                // Interruption began, take appropriate actions (save state, update user interface)
                self.avPlayer.pause()
            } else if type == .ended {
                guard let optionsValue =
                    info[AVAudioSessionInterruptionOptionKey] as? UInt else {
                        return
                }
                let options = AVAudioSession.InterruptionOptions(rawValue: optionsValue)
                if options.contains(.shouldResume) {
                    // Interruption Ended - playback should resume
                    self.avPlayer.play()
                }
            }
        }

        func resumeAllAnimations() {
            self.avPlayer.play()
            if vcForList?.avPlayer != nil {
                vcForList?.avPlayer.play()
            }
            if vcForConnect?.avPlayer != nil {
                vcForConnect?.avPlayer.play()
            }
            if vcForConnect?.avPlayerBG != nil {
                vcForConnect?.avPlayerBG.play()
            }
        }
        ...
    }

I then resume the animations by calling resumeAllAnimations() in applicationDidBecomeActive(_:) in AppDelegate.swift like so:

func applicationDidBecomeActive(_ application: UIApplication) {
        VideoPlayer.shared.resumeAllAnimations()
        ...
}

Resume AVAudioPlayer after phone call not working

I tried to do the same, although I didn't use any options in the setActive method.

There seem to be a bug in iOS 9.3.1 that doesn't resume playback of the AVAudioPlayer after the phone call ends.

Here is a snippet of what solved it for me: (Sorry for the Objective-C)

- (void)handleInterruption:(NSNotification *) notification{
    if (notification.name != AVAudioSessionInterruptionNotification || notification.userInfo == nil) {
        return;
    }

    NSDictionary *info = notification.userInfo;

    if ([notification.name isEqualToString:AVAudioSessionInterruptionNotification]) {

        if ([[info valueForKey:AVAudioSessionInterruptionTypeKey] isEqualToNumber:[NSNumber numberWithInt:AVAudioSessionInterruptionTypeBegan]]) {
            NSLog(@"InterruptionTypeBegan");
        } else {
            NSLog(@"InterruptionTypeEnded");

            //*The* Workaround - Add a small delay to the avplayer's play call; Without the delay, the playback will *not* be resumed
            //
            //(I didn't play much with the times, but 0.01 works with my iPhone 6S 9.3.1)
            dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 0.01 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
                NSLog(@"playing");
                [_player play];
            });
        }
    }
}

I added a small delay to the player's play call, and it worked.

I submitted a radar to Apple, hopefully it'll get fixed on the next release.

How to resume background audio in Swift 2 / AVPlayer?

Finally got it!

Solution: added the mixable option by changing the setCategory line to be:

AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback,
                                            withOptions: .mixWithOthers )
