We have an HLS video stream which is failing to play in AVPlayer but plays on ExoPlayer. AVPlayer throws the above error code, which we cannot find any reference to or help with understanding what exactly is AVPlayer doing (or finds unacceptable with the stream).
We'd like to know what causes this error to be thrown. We see this when HLS segments are authored from an MP4 with some questionable I and P frame data near the end of the container.
The error is thrown on iOS 14.7.1 AVPlayer.
