When playing back video on Wikimedia sites it would be helpful to playback content, particularly video, at different speeds. For instance, it might be helpful to slow down the video content to .5x (half) the default playback speed to capture fast moving action. For a "talking head" video where the watcher would like to save time, perhaps a 2x (double) speed playback would make consuming the information take less time.
Another potential scenario is during moderation of content, reviewers could reduce the amount of time it takes to review video content by playing videos back at a higher rate of speed (perhaps even 3x or higher).
Steps to Reproduce
Attempt to playback a video on any Wikimedia site. Commons is an obvious good choice for video content.
The current video player does not provide any speed setting other than the default 1x setting.
The video player would provide speed playback settings with a range both below and above the default playback setting.
