The error occurs on article pages, but is being amplified by appearance on Special:MediaSearch which may want to do something on the short term.

This is one of the most commonly-occurring errors on Special:MediaSearch right now, according to the new dedicated dashboard for the page.
This error comes from the video.js player that comes with TimedMediaHandler. I think that this error could potentially be addressed by bumping video.js to at least version 7.11.1 (here is the changelog, which includes a fix for what appears to be the same issue). We currently use version 7.7.4. The error may have something to do with the creation of multiple instances of a video player on a single page, something that happens in our video search tab all the time, but would also happen on article pages with multiple embedded videos; stand-alone file pages for a single video may not exhibit the error.
@brion is a Video.js version bump from 7.7.4 -> 7.11.1 or newer something that would be easily done in TMH? If so we could try that and see if this error goes away.
