Export HTML5 <video> tags?

[edent]

When exporting a video, is it possible to auto-generate an HTML5 <video> snippet which includes the thumbnail, codecs, etc?

I was thinking something like

<video poster="thumbnail.jpg" >
  <source src="file.mp4" type="video/mp4; codecs=mp4a.40.2, avc1.42001E">
  <source src="file.webm" type="video/webm; codecs=vorbis, vp8.0">
  <track kind="subtitles" src="file.srt">
</video>

I thinkt that's out of scope of youtube-dl, use the --write-info-json or --dump-json and write a script that process the json dict and creates the snippet.
