Hi, I'm working on an app where a user can scroll through a feed of short videos (a bit like TikTok). I do some pre-fetching of videos a couple positions ahead of the user's scroll position, so the video can start playing as soon as he or she scrolls to the video. Currently, I just pre-fetch by initializing a few AVPlayers. However, I'd like to add a better caching system. I'm looking for the best way to: get videos to start playing as possible, while making sure to minimize re-downloading of videos if a user scrolls away from a video and back to it. Is there a way that I can cache the contents of an AVPlayer that has loaded an HLS video? Alternatively, I've explored using AVAssetDownloadTask to download the HLS videos. My issue is that I can't download the full video and then play it - I need to start playing the video as soon as the user scrolls to it, even if it's not done downloading. Is there a way to start an HLS download with an AVAssetDownloadTask, and then start playing the video while it continues downloading? Thank you!
