I wanted to try out the new VideoPlayer view for SwiftUI so got setup on the beta but I've found that it seems all AVPlayer code (that works fine on iOS 13) fails to get playback on iOS 14 beta. This is happening in both SwiftUI and UIKit projects.

An existing SwiftUI project that hooked into AVPlayerLayer demonstrating the issue can be found here: https://github.com/ChrisMash/AVPlayer-SwiftUI

Or, starting a new SwiftUI project in Xcode 12 beta and swapping the ContentView for this:
Code Block 
import SwiftUI
import AVKit
struct ContentView: View {
   private let player = AVPlayer(url: URL(string: "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8")!)
   
   var body: some View {
     VideoPlayer(player: player)
   }
}

Results in no playback and the following in the console:

The playlist must be downloading ok as it figures out the duration and the bounds of the video are determined, but no segments play back.

The same happens trying to playback audio, such as the one used here: https://github.com/ChrisMash/AVPlayer-SwiftUI/blob/master/AVPlayer-SwiftUI/AudioView.swift#L101
