Use local file as cover image if fetching external thumbnails is disabled

[aesulus]

For external (e.g. YouTube) embeds, if $wgEmbedVideoRequireConsent = true and $wgEmbedVideoFetchExternalThumbnails = false, then the embed will be covered with a gray screen saying "Click to show content".

Is it possible to specify a local file to use as the cover image instead of the gray screen? If so, what is the wikitext syntax? If not, can this be added as an argument to the #ev parser function?

This is currently not possible. But as this seems like a very useful feature, I'll add it in the next release. :)

Should now work using develop branch.

See example 4 and 5, you can add |thumbnail=File:... and |title=... anywhere on the #ev parser function

Great! I can't wait until this makes it to a stable release. I'd love to test it on our wiki, but unfortunately, I'm constrained.

This is beyond my original issue, but why is it |thumbnail= for external videos but |cover= for local videos?

Also, why not make every unnamed parameter a named parameter too?

[octfx]

The thumbnail cover naming was indeed an unnecessary inconsistency. Both parameters are now called cover.

Since refactoring the extension every parameter can already be called as a named parameter, but the documentation was lacking.
I've updated the readme to include some examples of using named parameres, thanks for pointing this out!

Release v3.0.6 should include your requested feature.

Working as expected
