In our tvOS app we have to inject some tiny bit of data in the master manifest and leave the rest as is. The idea I was trying to implement here is intercepting the master manifest request with use of AVAssetResourceLoaderDelegate, and just redirect all consequent request, so AVKit can handle it on its own. In order to actually mimic the original requests, I made a copy of what is in AVAssetResourceLoadingRequest and adjusted only the parts required: override func resourceLoader(_ resourceLoader: AVAssetResourceLoader, shouldWaitForLoadingOfRequestedResource loadingRequest: AVAssetResourceLoadingRequest) -> Bool {     guard let url = loadingRequest.request.url, url.scheme == Self.assetScheme else {         return super.resourceLoader(resourceLoader, shouldWaitForLoadingOfRequestedResource: loadingRequest)     }     guard var urlComponents = URLComponents(url: url, resolvingAgainstBaseURL: false) else {         LOG.error("Could not obtain url components from resource request: \(loadingRequest.request)")         return super.resourceLoader(resourceLoader, shouldWaitForLoadingOfRequestedResource: loadingRequest)     }     urlComponents.scheme = "https"     guard let assetURL = try? urlComponents.asURL() else {         LOG.error("Could not make url from URL components \(urlComponents)")         return super.resourceLoader(resourceLoader, shouldWaitForLoadingOfRequestedResource: loadingRequest)     }     let assetURLRequest = (loadingRequest.request as NSURLRequest).mutableCopy() as? NSMutableURLRequest     assetURLRequest?.url = assetURL     guard let taskRequest = assetURLRequest?.copy() as? URLRequest else {         LOG.error("Could not convert url request \(String(describing: assetURLRequest))")         return super.resourceLoader(resourceLoader, shouldWaitForLoadingOfRequestedResource: loadingRequest)     }     if url == masterManifestURL {         // ...custom logic comes here...     } else {         loadingRequest.response = HTTPURLResponse(url: assetURL, statusCode: 302, httpVersion: "HTTP/1.1", headerFields: nil)         loadingRequest.redirect = taskRequest         loadingRequest.finishLoading()     }     return true } That works just fine, but only for VOD assets. For linear/live assets however only first bunch of data is loaded, when it ends, player does not request the next part of the sliding window and it hangs loading. I believe that the problem is somewhere with the custom logic, so I decided to list it separately: urlSession.dataTask(with: taskRequest) { [weak self] data, response, error in     loadingRequest.response = response     if let data = data, let dataRequest = loadingRequest.dataRequest, let self = self, let manifestString = String(data: data, encoding: .utf8) {         let adjustedManifestString = self.adjustAudioMetadataForManifest(manifestString)         if let adjustedData = adjustedManifestString.data(using: .utf8) {             dataRequest.respond(with: adjustedData)         } else {             LOG.error("Could not complement audio labels in master manifest")             dataRequest.respond(with: data)         }     }     if let error = error {         loadingRequest.finishLoading(with: error)     } else {         loadingRequest.finishLoading()     } }.resume() I noticed that unlike apple player, the custom resource loader requests have different encoding headers. It also was not clear whether data length and offset is more crucial for linear than it is for VOD, so I added this header as well: if let dataReq = loadingRequest.dataRequest, !dataReq.requestsAllDataToEndOfResource {     let offsetEnd = dataRequest.requestedOffset + dataRequest.requestedLength - 1     assetURLRequest?.addValue("bytes=\(dataReq.requestedOffset)-\(offsetEnd)", forHTTPHeaderField: "Range") } if loadingRequest.contentInformationRequest != nil {     assetURLRequest?.setValue("identity", forHTTPHeaderField: "Accept-Encoding") } I also fulfilled contentInformationRequest which I forgot originally (but it still worked for VOD): if let contentInformationRequest = loadingRequest.contentInformationRequest {     contentInformationRequest.contentLength = Int64.max     if let mimeType = response?.mimeType {         let utiType = UTTypeCreatePreferredIdentifierForTag(kUTTagClassMIMEType, mimeType as CFString, nil)         contentInformationRequest.contentType = utiType?.takeRetainedValue() as? String     }     contentInformationRequest.isByteRangeAccessSupported = true } and finally adjusted the data response with requested length: if dataRequest.requestsAllDataToEndOfResource {     dataRequest.respond(with: dataToRespond) } else {     let offsetStart = Int(dataRequest.requestedOffset)     let offsetEnd = Int(dataRequest.requestedOffset + dataRequest.requestedLength)     dataRequest.respond(with: dataToRespond[offsetStart ..< offsetEnd]) } All those adjustments happen only for master manifest request, and I just redirect all other request to proper url with https schema. Unfortunately all adjustments don't seem to make any difference. All work equally good with VOD assets but doesn't allow linear assets to play beyond the the very first video record (so sliding window just hangs) Is there some documentation on how to properly do the custom resource loader for a linear/live asset I can refer to in order to make it work?

We have both an iOS app and a tvOS app. We'd love to achieve the following scenario: iOS app should be able to detect Apple TV devices in the local network. When the user selects the apple TV device, check if the our tvOS app on apple TV is installed or not on the selected apple tv, If the app is not installed then iOS app can open the app store to launch the install page for the tvOS app on apple tv. The user can download/installation the app of the tvOS app. If the tvOS app is installed then launch the tvOS App on the apple TV. Are there any APIs available to achieve this scenario?

I put a supervised Apple TV in sigle app mode. Things were working fine until I unplugged the device from power.After replugging power, the designated app restarted correctly, but the Apple TV lost its pairing with the Mac I previously used for the configuration and there is not way to make it visible again. Choosing paired devices from the Apple Configurator 2 won't show anything.Even unplugging or trying a reset via remote (menu+home for 6 seconds) won't improve the situation: the Apple TV just restarts with the designated app and won't show up among paired devices.Even Xcode won't show the Apple TV among connected devices.Is there any way to exit from this ? Is there a way to force disable single app mode ? (so to at least gain access to Apple TV's settings menu)

I'm able to build and run the TV app with the TVTopShelf extension on simulators and physical Apple TVs but I get an error when I try to validate (or distribute) the archive built from XCode. The error says: App Store Connect Operation Error - Asset validation failed The log files don't provide more information: "Error Domain=ContentDelivery Code=90362 "App Store Connect Operation Error" UserInfo={IDEDistributionIssueSeverity=3, NSLocalizedDescription=App Store Connect Operation Error, NSLocalizedRecoverySuggestion=Asset validation failed}" As far as I know the certificate, the identifiers and the provisioning profiles for both the tvOS app and the TVTopShelf extension are OK. When I choose to manually select signing options, I can set the provisioning profiles for both the app and the extension and XCode does not complain about them. Is there something specific to know when distributing an app with an extension app? Is there some configuration to set on AppStoreConnect side? Or common pitfalls to avoid? Thanks for your help.

Is is possible now to create your own channel for Apple TV that can serve video content?
