Please add the following domain to the wgCopyUploadsDomains whitelist:
*.webm.naturalis.nl
for http://webm.naturalis.nl
Example
http://webm.naturalis.nl/RMNH.AVES.107865.webm (video of rotating mounted extinct bird skin)
Explanation
Naturalis Biodiversity Center at Leiden has donated some 4000 images and wants to give many more, for example 137 bird videos like the one shown.
I am temporary wikipedian in residence at NBC to help them.
Project site: https://en.wikipedia.org/wiki/Wikipedia:GLAM/Naturalis
This year another domain of NBC was whitelisted here for the same project: medialib.naturalis.nl, their special image library.
However, it is not clear whether an extra .webm format is allowed there. A MP4 version of these videos already resides there.
So i ask(ed) for this other domain as a workaround for upload.
Thank you for considering this request,
Kind regards,
