I'd go for captureTime -- similar to how it works in [requestVideoFrameCallback](https://wicg.github.io/video-rvfc/#dom-videoframemetadata-capturetime) - @drkron can explain the details. Downside of this is that it is best effort and requires SR or rtrr for clock offset estimation so it won't be available on every frame.
