Area: AV Playback Summary: When scrubbing to the very beginning of a live event stream, AVPlayerViewController tries to seek a non seekable position. Steps to Reproduce: A project reproducing the problem can be found here https://github.com/dcordero/Radar-31271447 Scrubbing to the very begining fails. The result is seeking back to live or in case of waiting for a longer time getting a frozen player. You will get a trace "Seeking a not longer seekable position" in the console coming from the following code in ViewController.swift which probes that the targetTime is lower than the first seekable time. func playerViewController(_ playerViewController: AVPlayerViewController, timeToSeekAfterUserNavigatedFrom oldTime: CMTime, to targetTime: CMTime) -> CMTime { if let firstSeekableRange = playerViewController.player?.currentItem?.seekableTimeRanges.first?.timeRangeValue { if targetTime < firstSeekableRange.start { print("Seeking a not longer seekable position") } } return targetTime } Expected Results: Scrubbing to the very beginning plays the content from the begining of the available window Actual Results: The result is seeking back to live or in case of waiting for a longer time getting a frozen player.
