Bitrate in TVMLKit JS media player

Question

How to get bit rate information from the TVMLKit JS player object? In apple documentation(https://developer.apple.com/documentation/tvmljs/player), I am not able to identify any attribute/method that returns this particular information. Is this possible to get this information?

Doesn't seem like there is any way to read the player item's access log from JS. At least none that I have been able to find either.

However, if you have access to the native code, as a workaround, you can listen for the AVPlayerItemNewAccessLogEntry notification.

Not the perfect solution, but perhaps it's enough for your use-case.

// Add observer somewhere.
NotificationCenter.default.addObserver(self, selector: #selector(accessLog(notification:)), name: .AVPlayerItemNewAccessLogEntry, object: nil)

@objc func accessLog(notification: Notification) {
    guard let playerItem = notification.object as? AVPlayerItem,
          let accessLogEvent = playerItem.accessLog()?.events.last
    else { return }
    _ = accessLogEvent.observedBitrate
}
