Google Chromecast Warning

We've received an email stating the following:

Important: Upcoming changes to Google Cast SDK for iOS 13 needed for your app

We are asking all developers to update their iOS apps to the latest version of the Google Cast SDK (v4.4.4) released on August 12, 2019.

With the upcoming release of iOS 13, there are additional privacy controls which will cause new authorization dialogs to appear to users of apps that use the Cast iOS SDK.

We understand that triggering new dialogs may not be ideal for your app. To address this concern and to improve how the SDK works with iOS 13, the Google Cast team implemented changes in our new releases.

We are making two versions of the Cast iOS SDK available to developers,

- One which includes Guest Mode support
The SDK with Guest Mode will prompt a new Bluetooth®-related permission.
- One which excludes Guest Mode support
The SDK without Guest Mode will not prompt any new permissions for Bluetooth®.
In addition, some system-level APIs relating to device discovery will change behaviors in iOS 13, and we will update the Google Cast SDK accordingly. We strongly recommend that you update your apps to the new SDK to avoid a degraded experience on iOS 13.

Additional details can be found at: https://developers.google.com/cast/docs/ios_sender/ios13_changes

We don't use Google Cast SDK directly, but through your SDK, so we would make you know that you should update this component as soon as possible.
Is there any new version solving this problem to be released soon?
Thank you very much,
Oscar

Cannot build PlayKit on iOS 13 with Xcode 11.3.1

I created a sample project with PlayKit as a dependency. When I try to run the xcworkspace after pod install I get compile errors in PlayKit.
I'm using the latest release 3.16.1 with Xcode 11.3.1 (11C504) for iOS 13.

Prerequisites

• Have you checked for duplicate issues: yes
• Which Player version are you using: 3.16.1
• Can you reproduce the issue with our latest release version: yes
• Can you reproduce the issue with the latest code from master: didn't check, master is behind release 3.16.1
• What devices and OS versions are you using: iOS 13, tried to build it on a simulator
• If applicable, add test code or test page to reproduce: see example project KalturaTest.zip

Expected behavior

I can use PlayKit as a dependency on an iOS 13 project with Xcode 11.3.1 and Swift 5.1.

Actual behavior

PlayKit does not compile as a dependency on an iOS 13 project with Xcode 11.3.1 and Swift 5.1.

PlayerEvent.tracksAvailable observer does not have videoTracks as Android does

Prerequisites

• Have you checked for duplicate issues: Yes
• Which Player version are you using: v3.28.0
• Can you reproduce the issue with our latest release version: Yes
• Can you reproduce the issue with the latest code from master: Yes
• What devices and OS versions are you using: iOS 17.0
• If applicable, add test code or test page to reproduce:

playKit.player?.addObserver(self, event: PlayerEvent.tracksAvailable) { [weak self] event in
    dump(event.tracks)
}

Expected behavior

Receiving videoTracks details as playkit-android does

Actual behavior

Only textTracks and audioTracks will be returned

Console output

ANDROID:

IOS:

Is there a way to know the width and height size of the current video track without having the videoTracks from PlayerEvent.tracksAvailable?
Is it possible to implement the same behaviour of Android's PlayerEvent.tracksAvailable observer/listener?

Thanks

Seeking while session is connected to Airplay crashes the SDK and the app

Prerequisites

• Which Player version are you using: issue first encountered on version 3.3.5 and after updating to 3.4.1 issue still persists
• Can you reproduce the issue with our latest release version: Can be reproduced with 3.4.1 (latest version at the current time)
• Can you reproduce the issue with the latest code from master: Issue can be reproduce with code from master
• What devices and OS versions are you using:
  • iPhone X running iOS 11.3.4
  • iPhone X running iOS 11.4
  • iPhone 6S running iOS 10.3.1
  • iPhone 8 Plus
  • iPhone 7 running iOS 11

In order to trigger the crash it is needed to enable Airplay and play a video content with Airplay while seeking back and forth from the player

Expected behavior

Video should seek to the desired position selected (seeking more than 1 time is probably needed as this seems to happen at random)

Actual behavior

Player tries to seek to position but crashes

Console output

Output in console ->

Crash when adding periodic time observers - depending on intervals and the order they are added

Prerequisites

• Have you checked for duplicate issues: YES
• Which Player version are you using: 3.19.0
• Can you reproduce the issue with our latest release version: YES
• Can you reproduce the issue with the latest code from master: YES
• What devices and OS versions are you using: iOS 14.2 (simulator)
• If applicable, add test code or test page to reproduce:

What's the problem?

When adding periodic time observers to a Player, depending on the intervals and order that they are added, it can cause a crash.

• The player controller adds an observer of its own with an interval of 0.1s

Then I'm adding two time observers:

• First for a custom analytics plugin with a 0.5s interval.
• Then for custom controls with a 0.2s interval.

This causes an immediate crash on adding the third observer:

2020-12-15 10:47:06.837 [Debug] [PlayerController+TimeMonitor.swift:16] addPeriodicObserver(interval:observeOn:using:) > add periodic observer with interval: 0.2, on queue: Optional(<OS_dispatch_queue_main: com.apple.main-thread[0x103a58c80] = { xref = -2147483648, ref = -2147483648, sref = 1, target = com.apple.root.default-qos.overcommit[0x103a59100], width = 0x1, state = 0x001ffe9000000300, dirty, in-flight = 0, thread = 0x303 }>)
Fatal error: Unexpectedly found nil while unwrapping an Optional value: file PlayKit/TimeObserver.swift, line 171

However, if you reverse that, adding the shorter 0.2s observer before the 0.5s one, it works fine.

The culprit appears to be in addPeriodicObserver(...) where it tries to find an existing observation to add the incoming block to - it's looking at an item from the periodicObservationsMap rather than the full list of periodicObservations.

} else if let periodicObservations = self.periodicObservationsMap[intervalMs] { // we already have this interval
            // get the observation with same interval
            var periodicObservation = periodicObservations.first(where: { $0.interval == intervalMs })!

From what I understand of the periodicObservationsMap the keys are for the trigger times rather than the intervals - so the new interval may or may not be in the right place in the map (pseudocode):

a = Observer(100)
addObserver(a)
--- periodicObservations = [a]
--- periodicObservationsMap = [100:[a]]

b = Observer(500)
addObserver(b)
--- looks for periodicObservationsMap[500] – which doesn't exist yet – so it adds the observer to periodicObservations and regenerates the map
--- periodicObservations = [a,b]
--- periodicObservationsMap = [100:[a] , 200:[a], 300:[a], 400:[a], 500:[a,b]]

c = Observer(200)
addObserver(c)
--- looks for periodicObservationsMap[200] – which contains [a]
--- find first in [a] where interval == 200 – but the interval of a is 100 so zero results and crash

EXPECTED:
--- periodicObservationsMap = [100:[a] , 200:[a,c], 300:[a], 400:[a], 500:[a,b]]

Seems it should be looking for these existing observers in self.periodicObservations rather than self.periodicObservationsMap

Will put a PR in for this shortly.

Swift package manager support

PlayKit by Kaltura is the only restraint for us to use Swift package manager in our project.
We've been waiting for SPM support for a very long time.
Please provide SPM support.

AirPlay not working for downloaded videos

We are unable to AirPlay downloaded videos with the Kaltura iOS frameworks. The HLS(.m3u8) video files are downloaded using the DownloadToGo framework and are played using the PlayKit framework.

Steps to reproduce:

1. Download HLS video file from remote
2. AirPlay video to an external device (i.e. Macbook Pro)
3. Play video.

We are using the following framework versions managed by cocoapods in our project:
PlayKit: 3.25.0
PlayKit Providers: 1.10.0
PlayKitKava: 1.6.0
DownloadToGo: 3.15.0
KalturaClient: 14.1.0

Note: If the content is not downloaded and is being streamed then AirPlay works correctly

Prerequisites

• Have you checked for duplicate issues: Y
• Which Player version are you using: 3.25.0
• Can you reproduce the issue with our latest release version: Y
• Can you reproduce the issue with the latest code from master:
• What devices and OS versions are you using: iPhone 15.3.1 and MacOS 12.1
• If applicable, add test code or test page to reproduce:

            let url = try contentManager.itemPlaybackUrl(id: entryId)           
            let localAssetsManager = LocalAssetsManager.managerWithDefaultDataStore()
            let mediaEntry = localAssetsManager.createLocalMediaEntry(for: entryId, localURL: url)
            let mediaConfig = MediaConfig(mediaEntry: mediaEntry, startTime: startTime)
            player.prepare(mediaConfig)

Expected behavior

Video is played on the target AirPlay device

Actual behavior

Video cannot be played on the target AirPlay device

How to get different resolutions of video by using entityId?

Pause, Seeking and Seeked events are not emitted when using Airplay mode with the Apple TV remote

Pause, Seeking and Seeked events are not emitted when using Airplay mode with the Apple TV remote

Steps to reproduce:

In our app we have a simple Kaltura Playkit player with a pause/play button, a slider and a MPVolumeView to airplay when available.

1. Choose airplay to apple tv
2. Start playing the video
3. Pause and play again with the apple tv remote controller
4. Seek with the apple tv remote controller

Result: The pause, seeking and seeked events are never emitted. When the player is paused on the Apple TV, the controllers on the device (iPhone) still look as if it is playing because it's not on paused state.

Expected result: Pause, play, seeking and seeked events are emitted even when interacting with the Apple TV remote controller in airplay mode. The controllers in the device always match the state in the Apple TV

Prerequisites

• Have you checked for duplicate issues: Yes, there are no duplicates for this issue.
• Which Player version are you using: 3.21
• Can you reproduce the issue with our latest release version: Yes
• Can you reproduce the issue with the latest code from master: Yes
• What devices and OS versions are you using: iPhone Xs iOS 14.4.2
• If applicable, add test code or test page to reproduce:

Expected behavior

It's a simple kaltura playkit player with the button to airplay. I reproduce in airplay mode, when I pause or seek with the apple tv remote, I get kaltura PlayEvents for Pause, Seeking and Seeked. The UI in the device is in sync with the apple tv player, for example:if it is pause it shows the play button and viceversa.

Actual behavior

I reproduce in airplay mode, when I pause or seek with the apple tv remote, I don't get any of the following kaltura PlayEvents: Pause, Seeking and Seeked. The UI in the device is not in sync with the apple tv player, for example: if it is paused in apple tv it still shows the pause button on the device, even though it should be showing the play button instead.

Issue on preferredPeakBitRate

I'm setting bitrate with: player.settings.network.preferredPeakBitRate = prefferedBitRate

and nothing happens ... can you provide example for bitrate in samples ?

App crashing when trying to use instantiate and use second instance of Player in iOS 10 and iOS 11.

Steps:

1. Play a video
2. Play another video using another instance of Player
3. The app crashes

Basically, when trying to create multiple players by destroying older players, the app is crashing.
This issue was not happening till v3.14.0

iOS version: 10 and 11(till 11.2)
Playkit version: v3.16.0

I am getting the below crash log:

Playkit_IMA support for Picture in Picture

I've been trying to support ads for picture in picture using Kaltura SDK but it seems there's no way to support this via Playkit_IMA.

I've read some documentation about using Google IMA with picture in picture but it seems this documentation is not helping when trying to use Playkit_IMA with picture in picture.
Link for the documentation: https://developers.google.com/interactive-media-ads/docs/sdks/ios/client-side/picture_in_picture

My questions is, does Kaltura support ads via Playkit_IMA using picture in picture or is there other way in which this can be done?

Privacy Manifest for a module as per Apple guidelines

Hi Team,
Apple has announced to have privacy manifest file (PrivacyInfo.xcprivacy) for third party SDKs. For more details, please visit:
https://developer.apple.com/support/third-party-SDK-requirements/

Since Playkit Uses XCGLogger framework which internally uses "NSPrivacyAccessedAPICategoryFileTimestamp" APIs which they are planning to fix refering this issue :
https://github.com/DaveWoodCom/XCGLogger/issues/331

So, my query is, Do Playkit-ios team have plan to upgrade their repo, so we can get this change ?
