Status of WebM, Opus, VP9 support for video and audio elements

[ghost]

According to the blog, WebM, Opus, and VP9 are supported only when used with Media Source Extensions, but not with <video> or <audio> elements. So can we split each of these entries* into two entries, one for MSE and another for video/audio elements?

MSE uses the video/audio element, so that wouldn't be the right way to denote this. Let me check with the media team on the best way to describe this.

@jacobrossi Any updates on this one?

Note that this has changed in recent months with the addition of the Web Media Extensions pack; things seem to work in <video> and <audio> as directly-loaded files now. But I'm not 100% sure whether Web Media Extensions can be relied on as always-installed as of 1803 (it is also possible to manually uninstall it).
