Hi, I am using HLS playback for live broadcasting. I am using AVPlayerItem. In live, I found seekableDuration always have some offset from the latest moment compared to the same playback on Chrome or Android. As far as I have digged into, the difference approximately matches the recommendedTimeOffsetFromLive (usually 6~9 seconds on my tests). The problem is, I tried to minimize configuredTimeOffsetFromLive but it does not have any effect. Even if I set it to 1~2 seconds, it is always the same as recommendedTimeOffsetFromLive. I tried to change automaticallyPreservesTimeOffsetFromLive as well, but nothing seems working. How do these properties work and how can I make the time offset minimized?

Hi, my app displays a video as texture on SceneKit's SCNNode. Now I've just found that some videos looks different in iOS 16.4 from previous versions. The videos look more pale than they should be. I looked up some documents and set SCNDisableLinearSpaceRendering as true in info.plist, they look exactly what they should be but then the problem is that the other videos which already looked fine now turned different. But anyway it seems to relate to the linear or gamma color spaces regarding to this answer (https://developer.apple.com/forums/thread/710643). Definitely those problematic videos have some different color space setting or something. I am not really expert in these field, where should I start to dig in? Or how can I just make iOS 16.4 behave same as previous versions? It worked well for all the videos then. What was actually updated?
