The "video" label can not work

When I use video label like this, “<video src=“xxxxxx”></video>”, it only display a picture for me, and no video play.

So, I try the <frame src=“xxxx”></frame>, but it has some problem:

  1. The default board size is very small, I need use parameters like that “width” and “height” .
  2. The FullScreen button need to add the 'allowfullscreen=“true” '.
  3. The video always auto play.

I write the code “<video src=“xxxxxx”></video>” by Typora(https://typora.io/), it worked very well, I hope Obsidian can refer to this feature.
