Hi,I'm trying to use AVPlayer with custom URL loading. We have a custom NSURLProtocol subclass. But it seems [NSURLProtocol registerClass] does not work directly with AVPlayer in real device (see this thread).Now I'm trying to use AVAssetResourceLoaderDelegate to do the custom URL loading. However it is a bit confusing to me how the delegate will be triggered. The URL looks like this "https://<some_ip_address>:<port>/resource/", however the protocol is not standard HTTP/1.1 (it's QUIC based instead). I did something like following, but does not work:(delegate is implemented in a different file) AVURLAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil]; AVAssetResourceLoader *resourceLoader = asset.resourceLoader; [resourceLoader setDelegate:delegate queue:dispatch_queue_create("MyURLDelegate loader", nil)]; AVPlayerItem *playerItem = [AVPlayerItem playerItemWithAsset:asset]; AVPlayer *player = [AVPlayer playerWithPlayerItem:playerItem]; AVPlayerViewController *controller = [[AVPlayerViewController alloc] init]; controller.player = player; [player play]; [self presentViewController:controller animated:false completion:^{}];With the above, I cannot see any methods are triggered in the delegate. What am I missing to allow the delegate to do custom URL loading for "https" URLs ? ThanksHan

Hi,I was posting a follow-up question to an old thread at here. But I am not sure if anyone would see it. Hence I took the liberty to post a separate thread. Thanks for understanding.I am using a custom protocol (Cronet network stack from Chromium) to play back video using AVPlayer. The code called [NSURLProtocol registerClass] to register its custom protocol and it works well in Xcode 11.3 iOS simulator testing. But the same code does not work on real device (iPhone, iOS 13). The old thread I referred above seems to suggest that AVPlayer would never "see" the registered custom protocol, but I am wondering why it worked in simulator. And is it still true in recent iOS versions that AVPlayer would use a separate process (mediaserverd ?) to play back the video hence ignoring the custom protocol? btw, I also tried to use AVAssetResourceLoaderDelegate to hijack the URL loading for AVPlayer, but did not work either in real device.Thanks.Han

Hi,I am writing my own HTTP web service server that supports iOS devices to view video files. On iOS I am using `AVPlayer` and on the server side it is simply `.mp4` files. But it seems like AVPlayer buffers for a long time (10+ seconds) before starting playing a video.After a bit debugging, it seems that AVPlayer send weird range values in its HTTP request for the video, for example:1st request headers send range 0-1: (this is OK)X-Playback-Session-Id: B1F3B5AE-B49A-40B1-8F2E-A501E1BC24AF Range: bytes=0-1 Accept: */* User-Agent: AppleCoreMedia/1.0.0.17A860 (iPhone; U; CPU OS 13_1_2 like Mac OS X; en_us) Accept-Language: en-us Accept-Encoding: identity Connection: keep-alive2nd request headers send range 0-37724087, which is full length of the video.This is weird, why doesn't AVPlayer take advantage of range header and ask for only a small range?X-Playback-Session-Id: B1F3B5AE-B49A-40B1-8F2E-A501E1BC24AF Range: bytes=0-37724087 Accept: */* User-Agent: AppleCoreMedia/1.0.0.17A860 (iPhone; U; CPU OS 13_1_2 like Mac OS X; en_us) Accept-Language: en-us Accept-Encoding: identity Connection: keep-alive3rd request headers send range of 37683200-37724087, which is the last chunk of the video.Again very weird, why does AVPlayer ask for the range that was already covered by the previous request?X-Playback-Session-Id: B1F3B5AE-B49A-40B1-8F2E-A501E1BC24AF Range: bytes=37683200-37724087 Accept: */* User-Agent: AppleCoreMedia/1.0.0.17A860 (iPhone; U; CPU OS 13_1_2 like Mac OS X; en_us) Accept-Language: en-us Accept-Encoding: identity Connection: keep-aliveAny ideas? Any comments or pointers are appreciated.

According to Wikipedia, Wi-Fi TDLS has been around for a number of years. Does iPhone (any model) support TDLS? If yes, how does it work? Does it need any help from the app by any means or fully automatic? Thanks in advance.
