iOS14 AVPlayer audio and video are out of sync

iOS14 AVPlayer audio and video are out of sync, and it will appear when you cast the screen, and occasionally when you don’t cast the screen. There is no problem with iOS13. Has anyone encountered it?
If it worked in 13 and doesn't in 14, please file a bug using the feedback assistant. Including a test project we can build & run to reproduce the issue will help move things along. At the very least, a file or URL for the movie/stream where the issue is shown is essential to diagnosing the issue.

Same. But only happens to some videos. Also happening in macOS in all system players (Safari, Quicktime). But works in Chrome on Mac.
