Just spotted in https://vimeo.com/180763356 source:

If we blindly pull some/all/first og:video:url
or og:video:secure_url
tags, we could get a crummy "application/x-shockwave-flash" SWF video.
Per http://ogp.me/#structured:
The
og:video
tag has the identical tags asog:image
. Here is an example:<meta property="og:video" content="http://example.com/movie.swf" /> <meta property="og:video:secure_url" content="https://secure.example.com/movie.swf" /> <meta property="og:video:type" content="application/x-shockwave-flash" /> <meta property="og:video:width" content="400" /> <meta property="og:video:height" content="300" />
Where og:image:type
is "A MIME type for this image."
Not sure how easy it'd be to use Fathom to extract the video metadata and then filter out anything with a mime type of "application/x-shockwave-flash" since a bunch of these properties are duplicated and seem to be in specific groups/orders.
Similarly, here's a YouTube example of duplicated HTML/SWF videos: https://www.youtube.com/watch?v=tja9cTzgq5k

<meta property="og:video:url" content="https://www.youtube.com/embed/tja9cTzgq5k">

<meta property="og:video:type" content="text/html">
<meta property="og:video:width" content="480">
<meta property="og:video:height" content="360">

<meta property="og:video:secure_url" content="https://www.youtube.com/v/tja9cTzgq5k?version=3&autohide=1">
