There is the code to add the cast button to the view controllers as UIBarButtonItem, but when i run the app it doesn't show up.Could I be missing something?

When calling GCKUIStyle.sharedInstance() the app crashes with the following message:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSDictionaryM setObject:forKey:]: object cannot be nil (key: playImage)'

I'm using Xcode 11.3 and SDK version 4.4.4.

Does anyone know how to solve?

Something went off the rails between 4.2 and 4.3 of the SDK.

$ ls -sh */GoogleCast.framework/GoogleCast
 46M GoogleCastSDK-ios-4.2.0/GoogleCast.framework/GoogleCast
631M GoogleCastSDK-ios-4.3.1_static/GoogleCast.framework/GoogleCast

631MB? Is this a joke?

In the demo I replaced the default .mp4 MediaInformations with a .m3u8 video, the local player works fine and the video plays as expected, but when I try to cast it, it fails (Shows a blackscreen with the "SAMPLE" words on it).

This is the MediaInformation I'm using

let mediaInfo = GCKMediaInformation(contentID: "https://bitdash-a.akamaihd.net/content/MI201109210084_1/m3u8s/f08e80da-bf1d-4e3d-8899-f0f6155f6efa.m3u8", streamType: .buffered,
                                            contentType: "application/x-mpegURL", metadata: metadata,
                                            streamDuration: kGCKInvalidTimeInterval,
                                            mediaTracks: nil,
                                            textTrackStyle: nil, customData: nil)

And this are some of the logs the app is showing.

MediaViewController: sessionManager didStartSession <0x106567460: GCKCastSession; state = 2>
switchToRemotePlayback; mediaInfo is Optional(<0x105bcd930: GCKMediaInformation; contentID = https://bitdash-a.akamaihd.net/content/MI201109210084_1/m3u8s/f08e80da-bf1d-4e3d-8899-f0f6155f6efa.m3u8>)

the logs shows that the media is being loaded to Chromecast but for some reason it's not playing properly. Any help? am I missing something in my MediaInformation or should be m3u8 loaded differently?

I would assume that GCKUIStyle.sharedInstance().castViews.mediaControl.sliderProgressColor = .green and GCKUIStyle.sharedInstance().castViews.deviceControl.sliderProgressColor = .green would work but it doesn't It only changes the color of the slider in the ExpandedController. I don't see another way to change this colors in the docs

Am I doing something wrong or is it a bug in the stlyer?

Hi

I am using Google cast sdk 3.3.0 and it is working fine with Chromecast device.

But its not detecting Sony Android TV with chromecast built in.

Do we need any extra setup to make it work?

Thanks

I am using the GoogleCastSDK inside my Framework Target ( using as an Umbrella Framework) , hence maybe I am facing issue using the Constant at runtime "kGCKMetadataKeyTitle". That is why I used string @"kGCKMetadataKeyTitle".

Q1. The following code is not return instance of GCKMediaMetadata ( i.e it is nil ) ?

GCKMediaMetadata *metadata = [[GCKMediaMetadata alloc] initWithMetadataType:GCKMediaMetadataTypeMovie];
[metadata setString:@"Movie Title" forKey:@"kGCKMetadataKeyTitle"];

So can I use other string instead of static string given by SDK ?

I am trying to create GCKMediaInformation following the documentation - GCKMediaInformation

Q2. Which of the fields of GCKMediaInformation are optional and which are not, as I am getting nil for following code .

GCKMediaInformation *info = [[GCKMediaInformation alloc] initWithContentID: contentID
             streamType: streamType
             contentType: contentType
             metadata: metadata
             streamDuration: streamDuration
             mediaTracks: nil
             textTrackStyle: textTrackStyle
             customData: nil]; 

So of-course as metadata is nil, maybe MediaInformation will be nil, but that is not clearly mentioned on documentation which of the fields are required ?

We've implemented logic to reconnect to devices as they come online, but we're running into an issue where the user swipes up to reveal the control center and turns airplane mode on, then repeats the action to turn airplane mode back off. When this occurs, all the devices go offline as expected, but the deviceScanner will not start scanning (with a breakpoint I see the _scanning property's value as NO) even after I call startScan. No devices are ever detected, presumably because the scanner is not and will not scan until I background the app and then return to it. Once backgrounding/returning to the app occurs, the scanner starts scanning and devices are immediately detected and come online. Is there anything else I can do to force the deviceScanner to start scanning without having to background and return to the app?

Hello,

I have a cryptic crash happening on initialization of my app which includes the Chromecast SDK. The crash happens intermediately after launch and only on iOS < 11 (10 and 9 confirmed)

The class involved is GCKDatabase which looks like an internal class. It is private and has no documentation so debugging is extremely difficult.

The application crashes in an Enterprise distribution only and doesn't crash when exported locally using XCode.

What possible causes must i consider?

Thanks

Hello. My name is Filip Thanks for your helpful source. I'm using this to integrate and expand our project for casting media. But i'm getting trouble with some issues.

• First, When the app goes into background, the google cast sdk close the socket, so my iphone disconnected from cast device.

I need to keep the session and not disconnect.

• Second, when i disconnected from device, i retry to connect manually, but i'm getting the following errors.

[GCKDeviceAuthChannel timerDidFire:] authentication timed out [GCKCastDeviceConnector deviceAuthChannel:didFailToAuthenticateWithError:] Not an authentic device, disconnecting. Error Domain=com.google.GCKError Code=3 "Device authentication failure" UserInfo={NSLocalizedDescription=Device authentication failure}

I don't understand why is that. When i try to connect first, there is no authentication error, but i retry to connect secondly, i'm getting authentication error.

Please help me. This is urgen issue for our project.

Thanks. Regards.

SDK Version: google-cast-sdk (4.6.1) iOS: 16.0

Expectation:

• Once I kill the application the current ongoing session should be ended currently it continually playing the video

What I have tried:

• Uses of end session:

    func applicationWillTerminate(_ application: UIApplication) {
             GCKCastContext.sharedInstance().discoveryManager.stopDiscovery()
             GCKCastContext.sharedInstance().sessionManager.endSession()
             GCKCastContext.sharedInstance().sessionManager.endSessionAndStopCasting(true)
    }

Hello!

I found that if a video is short and contains ads request at the same time - it crashes inside Google Cast SDK for iOS in this component [GCKUIMediaController computeAdBlocks:]

I can provide sample app for this issue. I downloaded Cast sample app for iOS and just added one my method func makeNewItem() -> GCKMediaInformation which creates "problematic" item. This item contains short video - https://storage.googleapis.com/interactive-media-ads/media/blank-0.2-sec.m4v and VMAP ad tag url.

Steps to reproduce

1. Run the app
2. Connect to Chromecast and play any video from the list with "Play now" option
3. I substitute the original item with the problematic item. In almost 100% of cases the app will crash with this crash stack below when the ad start on the Chromecast device
4. I found that this crash is not occurred if the video file duration is longer

I implemented and use chromecast almost OK. But when I tried to cast on chrome cast 3 by Guest Mode, I acidently got this error.
