MPRemoteCommandCenter doesn't appear on iOS13 - swift

I have a video player that show a .m3u8 stream. I've tried to implement the Remote Control but the widget doesn't appear both in lock screen, in the Notification Center and in the Command Center.
I need only to have play-pause, volume controls and some static info as Title, Artist and Artwork.
This is my code:
AppDelegate.swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback)
try AVAudioSession.sharedInstance().setActive(true)
} catch {
print(error.localizedDescription)
}
return true
}
ViewController.swift
class ViewController: UIViewController {
var player = AVPlayer()
var playerViewcontroller = AVPlayerViewController()
var playerItem: AVPlayerItem!
var playerLayer = AVPlayerLayer()
#IBAction func playVideo(_ sender: Any) {
guard let url = URL(string: "https://video.m3u8") else {
return
}
// Create an AVPlayer, passing it the HTTP Live Streaming URL.
playerItem = AVPlayerItem(url: url)
playerItem.preferredForwardBufferDuration = 8
player = AVPlayer(playerItem: playerItem)
// Create a new AVPlayerViewController and pass it a reference to the player.
playerViewcontroller.player = player
playerViewcontroller.showsPlaybackControls = true
// Modally present the player and call the player's play() method when complete.
present(playerViewcontroller, animated: true) {
self.player.play()
}
setupNowPlaying()
}
override func viewDidLoad() {
//super.viewDidLoad()
}
public func disconnectAVPlayer() {
playerViewcontroller.player = nil
}
public func reconnectAVPlayer() {
playerViewcontroller.player = player
}
func setupNowPlaying() {
print("_________________________________setupPlaying")
// Define Now Playing Info
let nowPlayingInfoCenter = MPNowPlayingInfoCenter.default()
var nowPlayingInfo = nowPlayingInfoCenter.nowPlayingInfo ?? [String: Any]()
let title = "TV NAME"
let album = "TV DESCRIPTION"
let image = UIImage(named: "ICON") ?? UIImage()
let artwork = MPMediaItemArtwork(boundsSize: image.size, requestHandler: { (_) -> UIImage in
return image
})
nowPlayingInfo[MPMediaItemPropertyTitle] = title
nowPlayingInfo[MPMediaItemPropertyAlbumTitle] = album
nowPlayingInfo[MPMediaItemPropertyArtwork] = artwork
nowPlayingInfo[MPNowPlayingInfoPropertyPlaybackRate] = NSNumber(value: 1.0)
nowPlayingInfoCenter.nowPlayingInfo = nowPlayingInfo
}
}
Hope that infos are sufficient. Thanks

Remote Control Works fine in iOS 13 , you just didn’t set it up first. Add this code after assigning to your AVPlayer
func commandCenterSetup() {
UIApplication.shared.beginReceivingRemoteControlEvents()
let commandCenter = MPRemoteCommandCenter.shared()
setupNowPlaying()
commandCenter.pauseCommand.addTarget { (event) -> MPRemoteCommandHandlerStatus in
print("PAUSE")
self.playerViewcontroller.player.pause()
return .success
}
commandCenter.playCommand.addTarget { (event) -> MPRemoteCommandHandlerStatus in
print("PLAY")
playerViewcontroller.player.play()
return .success
}
}

Swift: Parse does not load a video from URL

I am trying to stream a video from backend to my device.I have a video url from backend but screen displays nothing. However, youtube url it works. Can anyone guide me why this video is not playing and how can it be played? I am using pod 'YouTubePlayer' to play the video.
let cell: VideoTableViewCell = tableView.dequeueReusableCell(withIdentifier: "VideoTableViewCell") as! VideoTableViewCell
var query = PFQuery(className:"Videos")
query.getObjectInBackground(withId: "83kli72i62") { (parseObject, error) -> Void in
let videoFile = parseObject!["Question"] as! PFFileObject
self.videoUrl = videoFile.url
let url = NSURL(string: self.videoUrl! )
cell.playerView.loadVideoURL(url as! URL)
}
i have an app that is pulling videos from firebase and playing them with the avplayer, check out my code below and see how it works

define video url as the uiview in your class

My swift code should be able to take a snapshot of a video and then take that image and display in a uiimageview. Instead of using a online link I just want the url to be the uiview in my class.So the video url should be previewView not the https link that I have below. All the code below is in this class
import UIKit;import AVFoundation

Getting image from AVCaptureMovieFileOutput without switching

I would like to prevent lags when the app switches between video-recording and photo-taking: by using only AVCaptureMovieFileOutput and getting a snapshot from it when captured an image.
Just like how SnapChat does.
Is it possible somehow? I haven't found any releated articles about this.
I don't want to switch between outputs, because it lags
The code:
#IBOutlet var cameraView: UIView!
#IBOutlet var cameraSwitchButton: UIButton!
#IBOutlet var captureButtonView: CaptureButton!
#IBOutlet var cameraFlashButton: UIButton!
var captureSession = AVCaptureSession()
let movieOutput = AVCaptureMovieFileOutput()
var activeInput: AVCaptureDeviceInput!
var previewLayer = AVCaptureVideoPreviewLayer()
var outputURL: URL!
var connection : AVCaptureConnection!
override func viewDidLoad() {
if setupSession() {
setupPreview()
startSession()
connection = movieOutput.connection(with: AVMediaType.video)
if (connection?.isVideoStabilizationSupported)! {
connection?.preferredVideoStabilizationMode = AVCaptureVideoStabilizationMode.off
}
}
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(captureButtonTapped))
let longGesture = UILongPressGestureRecognizer(target: self, action: #selector(captureButtonLongPressed))
tapGesture.numberOfTapsRequired = 1
captureButtonView.addGestureRecognizer(tapGesture)
captureButtonView.addGestureRecognizer(longGesture)
}
#objc func captureButtonTapped(){
?? TAKE PHOTO HERE ??
}
var isRecordingVideo : Bool = false
#objc func captureButtonLongPressed(sender : UILongPressGestureRecognizer){
if sender.state == .began {
isRecordingVideo = true
startRecording()
captureButtonView.startTimer(duration: 10.0)

stopRecording()

I wasn't able to find a way using only AVCaptureMovieFileOutput, however you can add an additional photo output and trigger photos without having to switch between the outputs.
I'm short on time at the moment but this should get you going till I can edit with more info.
(See EDIT with full implementation below, and limited force unwrapping)
First off setup an additional var for a photo output in your view controller
// declare an additional camera output var
var cameraOutput = AVCapturePhotoOutput()
// do this in your 'setupSession' func where you setup your movie output
cameraOutput.isHighResolutionCaptureEnabled = true
captureSession.addOutput(cameraOutput)
Declare a function to capture your photo using the cameraOutput:
func capturePhoto() {
// create settings for your photo capture
let settings = AVCapturePhotoSettings()
let previewPixelType = settings.availablePreviewPhotoPixelFormatTypes.first!
let previewFormat = [
kCVPixelBufferPixelFormatTypeKey as String: previewPixelType,
kCVPixelBufferWidthKey as String: UIScreen.main.bounds.size.width,
kCVPixelBufferHeightKey as String: UIScreen.main.bounds.size.height
] as [String : Any]
settings.previewPhotoFormat = previewFormat
cameraOutput.capturePhoto(with: settings, delegate: self)
}
and conform to the AVCapturePhotoCaptureDelegate.
I created a separate class called VideoFeed to manage the video capture session, so this sample is an extension of that class. I'll update with more info on this later.
The loadImage(data: Data) function calls a delegate with the image. You can ignore that call if you put this directly in your view controller, and save or do whatever you like with the generated photo:
extension VideoFeed: AVCapturePhotoCaptureDelegate {
func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photoSampleBuffer: CMSampleBuffer?, previewPhoto previewPhotoSampleBuffer: CMSampleBuffer?, resolvedSettings: AVCaptureResolvedPhotoSettings, bracketSettings: AVCaptureBracketedStillImageSettings?, error: Error?) {
guard error == nil else {
print("Photo Error: \(String(describing: error))")
return
}
guard let sampleBuffer = photoSampleBuffer,
let previewBuffer = previewPhotoSampleBuffer,
let outputData = AVCapturePhotoOutput
.jpegPhotoDataRepresentation(forJPEGSampleBuffer: sampleBuffer, previewPhotoSampleBuffer: previewBuffer) else {
print("Oops, unable to create jpeg image")
return
}
print("captured photo...")
loadImage(data: outputData)
}
func loadImage(data: Data) {
let dataProvider = CGDataProvider(data: data as CFData)
let cgImageRef: CGImage! = CGImage(jpegDataProviderSource: dataProvider!, decode: nil, shouldInterpolate: true, intent: .defaultIntent)
let image = UIImage(cgImage: cgImageRef, scale: 1.0, orientation: UIImageOrientation.right)
// do whatever you like with the generated image here...
delegate?.processVideoSnapshot(image)
}
}
EDIT:
Here's the complete implementation I used in my test project.
First I moved all the AVFoundation specific code into it's own VideoFeed class and created some callbacks to the view controller.
This separates concerns and limits the view controllers responsibilities to:
Adding the preview layer to the view
Triggering and handling the captured image/screenshot
Starting/stopping video file recording.
Here's the ViewController implementation:
ViewController.swift
import UIKit
import AVFoundation
class ViewController: UIViewController, VideoFeedDelegate {
#IBOutlet var cameraView: UIView!
var videoFeed: VideoFeed?
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
// end session
videoFeed?.stopSession()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
// request camera access
AVCaptureDevice.requestAccess(for: AVMediaType.video) { [weak self] granted in
guard granted != false else {
// TODO: show UI stating camera cannot be used, update in settings app...
print("Camera access denied")
return
}
DispatchQueue.main.async {
if self?.videoFeed == nil {
// video access was enabled so setup video feed
self?.videoFeed = VideoFeed(delegate: self)
} else {
// video feed already available, restart session...
self?.videoFeed?.startSession()
}
}
}
}
// MARK: VideoFeedDelegate
func videoFeedSetup(with layer: AVCaptureVideoPreviewLayer) {
// set the layer size
layer.frame = cameraView.layer.bounds
// add to view
cameraView.layer.addSublayer(layer)
}
func processVideoSnapshot(_ image: UIImage?) {
// validate
guard let image = image else {
return
}
// SAVE IMAGE HERE IF DESIRED
// for now just showing in a lightbox/detail view controller
let storyboard = UIStoryboard(name: "Main", bundle: Bundle(for: AppDelegate.self))
let vc = storyboard.instantiateViewController(withIdentifier: "LightboxViewController") as! LightboxViewController
vc.previewImage = image
navigationController?.pushViewController(vc, animated: true)
}
#IBAction func captureButtonTapped(_ sender: Any){
// trigger photo capture from video feed...
// this will trigger a callback to the function above with the captured image
videoFeed?.capturePhoto()
}
}
Here's the full implementation of the VideoFeed class.
Using this approach allows you to reuse the video functionality in other projects more easily without having it tightly coupled to the view controller.
VideoFeed.swift
import UIKit
import AVFoundation
/// Defines callbacks associated with the VideoFeed class. Notifies delegate of significant events.

}

/// The output that handles saving the video stream to a file.

Record And Play Voice in Separate Class (Swift3)

I used many codes that was for record an play the voice, but most of them are not in swift3 and they don't work in my app.
This code works, but I want to create a separate class from the viewcontroller that do recording an playing voices. Also the mentioned github code is complex an I'm searching for a simplified code.
Update:
After recording, when I check existence of the recorded file, the file doesn't exist, and it raises EXC_BAD_ACCESS error on appDelegate.
What's wrong?
Any suggestions would be appreciated.
Try to record audio by wirting line
let isRec = AudioManager.shared.record(fileName: "rec")
if isRec returned true then recording is happening else not.
To finish recording use : let recordedURL = AudioManager.shared.finishRecording()
To play recorded file send above url to setupUpPlayer() function in manager class
Not to forget to use extension code snippets give below the code snippet which are delegate functions of AVAudioRecorder and AVAudioPlayer
import Foundation
import AVFoundation
class AudioManager: NSObject {
static let shared = AudioManager()
var recordingSession: AVAudioSession?
var recorder: AVAudioRecorder?
var meterTimer: Timer?
var recorderApc0: Float = 0
var recorderPeak0: Float = 0
//PLayer
var player: AVAudioPlayer?
var savedFileURL: URL?
func setup() {
recordingSession = AVAudioSession.sharedInstance()
do {
try recordingSession?.setCategory(AVAudioSessionCategoryPlayAndRecord, with: .defaultToSpeaker)
try recordingSession?.setActive(true)
recordingSession?.requestRecordPermission({ (allowed) in
if allowed {
print("Mic Authorised")
} else {
print("Mic not Authorised")
}
})
} catch {
print("Failed to set Category", error.localizedDescription)
}
}
func record(fileName: String) -> Bool {
setup()
let url = getUserPath().appendingPathComponent(fileName + ".m4a")
let audioURL = URL.init(fileURLWithPath: url.path)
let recordSettings: [String: Any] = [AVFormatIDKey: kAudioFormatMPEG4AAC,
AVEncoderAudioQualityKey: AVAudioQuality.high.rawValue,
AVNumberOfChannelsKey: 2,
AVSampleRateKey: 44100.0]
do {
recorder = try AVAudioRecorder.init(url: audioURL, settings: recordSettings)
recorder?.delegate = self
recorder?.isMeteringEnabled = true
recorder?.prepareToRecord()
recorder?.record()
self.meterTimer = Timer.scheduledTimer(withTimeInterval: 0.1, repeats: true, block: { (timer: Timer) in
//Update Recording Meter Values so we can track voice loudness
if let recorder = self.recorder {
recorder.updateMeters()
self.recorderApc0 = recorder.averagePower(forChannel: 0)
self.recorderPeak0 = recorder.peakPower(forChannel: 0)
}
})
savedFileURL = url
print("Recording")
return true
} catch {
print("Error Handling", error.localizedDescription)
return false
}
}
func getUserPath() -> URL {
return FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
}
func finishRecording() -> String {
recorder?.stop()
self.meterTimer?.invalidate()
var fileURL: String?
if let url: URL = recorder?.url {
fileURL = String(describing: url)
}
return /fileURL
}
//Player
func setupPlayer(_ url: URL) {
do {
try player = AVAudioPlayer.init(contentsOf: url)
} catch {
print("Error1", error.localizedDescription)
}
player?.prepareToPlay()
player?.play()
player?.volume = 1.0
player?.delegate = self
}
}
//MARK:- Audio Recorder Delegate
extension AudioManager: AVAudioRecorderDelegate {
func audioRecorderDidFinishRecording(_ recorder: AVAudioRecorder, successfully flag: Bool) {
print("AudioManager Finish Recording")
}
func audioRecorderEncodeErrorDidOccur(_ recorder: AVAudioRecorder, error: Error?) {
print("Encoding Error", /error?.localizedDescription)
}
}
//MARK:- Audio Player Delegates
extension AudioManager: AVAudioPlayerDelegate {
func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer,
successfully flag: Bool) {
player.stop()
print("Finish Playing")
}
func audioPlayerDecodeErrorDidOccur(_ player: AVAudioPlayer,
error: Error?) {
print(/error?.localizedDescription)
}
}

AVPlayer is not working when I'm trying to use with this YTVimeoExtractor

When I try to play the video through the AVPlayer, the video loads for some time(the loading symbol appears at the top of the player) then suddenly it stops and the play icon with a crossover is shown. Don't know what is wrong? I can get the video informations but I can't make the video to play.
I will show what I have done. Could anyone answer my question, help is much appreciated.
import UIKit
import AVKit
import AVFoundation

var playerVC : AVPlayerViewController!
var playerItem : AVPlayerItem!

var playerLayer: AVPlayerLayer!
#IBOutlet weak var videoURL: UITextField!
#IBOutlet weak var videoTitle: UILabel!
#IBAction func playVideo(sender: AnyObject) {
YTVimeoExtractor.sharedExtractor().fetchVideoWithVimeoURL(self.videoURL.text!, withReferer: nil, completionHandler: {(video, error) -> Void in
if video != nil {
// https://vimeo.com/165891648
self.videoTitle.text = video?.title
print("hello: \(self.videoTitle.text)")
let url = NSURL(string: self.videoURL.text!)
// let url = NSURL.init(fileURLWithPath: self.videoURL.text!)

This is the one I get on the simulator.
I used this https://github.com/lilfaf/YTVimeoExtractor one to do this sample project. You can try it out and let me know.
I had the same issue and fix using this way:
#IBAction func btnDownload_touchUpInside(_ sender: UIButton) {
YTVimeoExtractor.shared().fetchVideo(withVimeoURL: self.videoURL.text!, withReferer: nil, completionHandler: {(video, error) -> Void in
if video != nil {
self.videoTitle.text = video?.title
if let streamUrls = video?.streamURLs
{
var streamURL: String?
var streams : [String:String] = [:]
for (key,value) in streamUrls {
streams["\(key)"] = "\(value)"
print("\(key) || \(value)")
}
if let large = streams["720"]
{
streamURL = large
}
else if let high = streams["480"]
{
streamURL = high
}
else if let medium = streams["360"]
{
streamURL = medium
}
else if let low = streams["270"]
{
streamURL = low
}
if let url = streamURL
{
Alamofire.download(url, to: { (temporaryURL, response) -> (destinationURL: URL, options: DownloadRequest.DownloadOptions) in
if let directoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] as? NSURL {
let fileName = response.suggestedFilename!
let finalPath = directoryURL.appendingPathComponent(fileName)
self.downloadedVideoPath = finalPath?.absoluteString
return (finalPath!, DownloadRequest.DownloadOptions(rawValue: 2))
}
}).downloadProgress(closure: { (progress) in
print("Progress: \(progress.fractionCompleted)")
})
}
}
}
})
}
#IBAction func btnPlayOffLine_touchUpInside(_ sender: UIButton) {
YTVimeoExtractor.shared().fetchVideo(withVimeoURL: self.videoURL.text!, withReferer: nil, completionHandler: {(video, error) -> Void in

let player = AVPlayer(url: videoURL! as URL)

playerViewController.player = player
self.present(playerViewController, animated: true) {
playerViewController.player!.play()
}
}
})
}
