XCode：使用 Apple FairPlay 实现加密的 HLS

如何解决XCode：使用 Apple FairPlay 实现加密的 HLS

我尝试使用加密的 m3u8 实现 Apple FairPlay。我从 Apple Developer 获得了示例文件（下面的链接）并将其放入我的服务器中。

Apple Developer Test Streams

这是我的代码：

- (void)loadplayerView
{
    NSURL *url = [NSURL URLWithString:@"https://nyoba.innoplayer.co/cdn/videos/fairplay/muxed/encrypted/prog_index.m3u8"];
    
    AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:url options:nil];
    [asset.resourceLoader setDelegate:self queue:dispatch_get_main_queue()];
    
    AVPlayer *player = [[AVPlayer alloc] initWithPlayerItem:[AVPlayerItem playerItemWithAsset:asset]];
    
    AVPlayerViewController *controller = [[AVPlayerViewController alloc] init];
    controller.player = player;
    [self presentViewController:controller animated:YES completion:nil];
}

我已经实现了 AVAssetResourceLoaderDelegate，在设备中运行它并调用了这个方法。

- (BOOL)resourceLoader:(AVAssetResourceLoader *)resourceLoader shouldWaitForLoadingOfRequestedResource:(AVAssetResourceLoadingRequest *)loadingRequest
{
    Nsstring *keyURL = @"https://nyoba.innoplayer.co/cdn/videos/fairplay/muxed/encrypted/Key.txt";
    NSURL *urlx = [NSURL URLWithString:keyURL];
    
    NSMutableuRLRequest *urlRequest = [[NSMutableuRLRequest alloc] initWithURL:urlx];
    [urlRequest setTimeoutInterval:20];
    [urlRequest setHTTPMethod:@"GET"];
    
    NSURLSessionDataTask *task = [[NSURLSession sharedSession] dataTaskWithRequest:urlRequest completionHandler:^(NSData * _Nullable data,NSURLResponse * _Nullable response,NSError * _Nullable error) {
        
        NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
        NSLog(@"requestHLSKeyWithURL httpResponse ==== %ld",(long)httpResponse.statusCode);
        
        if (data != nil && (httpResponse.statusCode == 200 || httpResponse.statusCode == 100))
        {
            NSLog(@"requestHLSKeyWithURL data ==== %@",data);
            [[loadingRequest contentinformationRequest] setContentType:AVStreamingKeyDeliveryPersistentContentKeyType];
            [[loadingRequest contentinformationRequest] setByterangeAccessSupported:YES];
            [[loadingRequest contentinformationRequest] setContentLength:[data length]];
            [[loadingRequest dataRequest] respondWithData:data];
            [loadingRequest finishLoading];
        }
        else
        {
            NSLog(@"requestHLSKeyWithURL ==== NOT OK");
            [loadingRequest finishLoading];
        }
        
    }];
    
    [task resume];
    
    return YES;
}

问题是，当委托的方法被调用时，我试图[[loadingRequest dataRequest] respondWithData:data];。它什么也没发生，也没有显示任何东西。

有人能帮我解决这个问题吗？
