I'm using mediawiki 1.25.1.

It's in a secure environment at work so I can't share the URL.

I am embedding video using:

{{#video:[path_of_video.ogv]}}

I am trying to change the video thumbnail size by adding it to the end. For example:

{{#video:http://video_location/test_video.ogv | 100 }}

but it doesn't work. I couldn't find any documentation on this. Any help? Thanks.

Please upgrade. 1.25 has been unsupported for years and is full of security issues nowadays.

The use of {{#video:...}} function, as far as I know, is not available in MediaWiki by default. You will have to see which MediaWiki extension your Wiki is using which allows the use of that function. This can be done by taking a look at your Wiki's Special:Version page.
