I have successfully built a AVNavigationMarkersGroup (consisting of multiple AVTimedMetadataGroups), which I can attach to an AVPlayerItem before loading the video into an AVPlayer. However, there are two things I have not been able to do, and I wonder if this is possible:Dynamically update these markers after playback has started. This could have several reasons, e.g. not wanting to wait for a slow API, or new information becoming available. So far, I have noticed that when I set the navigationMarkerGroups property on an AVPlayerItem before I play the item, things are fine, but when I set it after the item has started, the whole app crashes.Attach artwork that is loaded via URL. Building an AVMetadataItem with the .commonIdentifierArtwork identifier is seemingly only possible with raw data, meaning I would have to wait for ALL artwork to completely download before I can build the markers. This would be especially problematic if markers have to be defined before playback starts.Am I missing something, or are these limitations intended?
