Steps to reproduce
Attempt to add a video to a note/page using HTML or Markdown syntax:

or
<video src="/absolute/path/to/video/file.mp4" controls></video>
And then publish the page.
Expected result
I expect a video embed to appear in the note/page on the published site.
Actual result
The video does not appear on the published site.
The video does appear when running locally (e.g. in the Windows app), but it does not appear on my published site.
Environment
- Operating system: Windows 10/Firefox/Edge
- Obsidian version: 0.12.12
Additional information
Video embedding does work on published sites using the wikilinks preview syntax:
![[absolute/path/to/file.mp4]]
Also, when using the HTML <video> element, the browser renders a player, but the video never loads. Looking at the network tab, it appears that the resource is never requested.
