Support ThePlatform feed embeds on National Geographic articles

[Fironet]

There's a video on this National Geographic page about the Trajan Column, and feeding youtube-dl the link reports the URL is unsupported, although youtube-dl lists NG as a supported site.

Here's a link to the video by itself. Any way to get youtube-dl to download this?

For the time being, you may download the video in question using this link:

Note to others:
The article contains an embedded ThePlatform feed, which we do not support yet.
