Hi,I tried to get a portrait image that captured with an IOS 13 iphone x device as CIImage with auxiliarySemanticSegmentationHairMatte option but it always returns nil.I also tried sample code that shared on https://developer.apple.com/videos/play/wwdc2019/225SSM tab that show segmentations always empty.

Hi,Our music application play hls which is served from streamer. We are caching these music as explained here : https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/MediaPlaybackGuide/Contents/Resources/en.lproj/HTTPLiveStreaming/HTTPLiveStreaming.htmlThis was working, but we started to get some complaints from our users that they say that music stops while listening and can not play to end time.These users which get this error, has these logs :Error Domain=AVFoundationErrorDomain Code=-11800 "İşlem tamamlanamadı" UserInfo={NSLocalizedFailureReason=Unknown Error (-12645), NSLocalizedDescription=Operation not completed, NSUnderlyingError=0x282c5ea90 {Error Domain=NSOSStatusErrorDomain Code=-12645 "(null)"}}And they are playing downloaded hls content. What is the main reason of this error and why only some of users have this error?
