I'm looking to expand a few things on https://www.mediawiki.org/wiki/Specs/HTML#Audio/Video

Upcoming work:

1. muted and loop attributes. T116501
   • [[File:videoOrAudio.webm|thumb|loop|muted|caption]]
   • These options will reflect as loop and muted options on audio and video elements <video src="VideoOrAudio.webm" loop muted></video>
   • These are boolean attributes (present or non-present) and do not have values
   • I'm assuming these also need to be tracked for the mw:Video element's via mw-data ? Where/how ?
2. playsinline https://gerrit.wikimedia.org/r/c/mediawiki/extensions/TimedMediaHandler/+/794592
   • [[File:videoOrAudio.webm|thumb|playsinline|caption]]
   • These option MIGHT reflect as (it is conditional) <video src="VideoOrAudio.webm" playsinline></video>
   • This is a video-only option, it cannot occur on <audio>
   • This is boolean attributes (present or non-present) and do not have values
   • This needs again to be added to mw:Video element's via mw-data ?
3. projection and or stereo hints T150624
   • [[File:videoOrAudio.webm|thumb|caption]], BUT the have a 'natural' aspect derived from the files contents, which needs to be communicated to the JS player via HTML.
   • These options MIGHT reflect as (it is conditional and not spec'ed yet) as <video src="VideoOrAudio.webm" data-projection="equirectangular" data-stereo="side-by-side"></video>.
   • These are image and video options
   • They have string values, multiple exclusive options (yet to be defined)
   • Where does this go ?
