Bug 208142

Summary:	Setting <video> playbackRate causes video playback disruption
Product:	WebKit	Reporter:	Jerry Jongerius <jerryj>

Description Jerry Jongerius 2020-02-24 09:17:55 PST

1. Visit https://www.w3.org/2010/05/video/mediaevents.html
2. Press "Bunny Movie" button
3. Press "Play()" button
4. Every time "PlaybackRate+=0.1" button is pressed, video playback is disrupted for a split second.

When an external slider is configured to set video playback rate, all that results during slider movement is that the video is mostly paused (whereas on Windows/Chrome, the video is still playing 100% of the time, just that speed is transparently changing -- which is the desired outcome).

This is the same issue, thanks.

This an issue with one of the frameworks WebKit uses, we are working with them to get a fix.
