Extension:VideoCache

The VideoCache extension allows for the caching of online videos to the local directory using yt-dlp. Cached files are added via the API, and can be retrieved on wiki pages.

The caching works purely based on the file system, so that multiple wikis can use the same cache.

Installation

 * Install yt-dlp, either as directed above, or through your package manager.
 * NOTE: Make sure your system has PHP 7.3+
 * Download and place the file(s) in a directory called VideoCache in your extensions/ folder
 * Add the following line to your LocalSettings.php
 * Configure as required

Parameters

 * $wgVideoCacheYtdlpLocation - The location of the yt-dlp program, defaults to /bin/yt-dlp
 * $wgVideoCacheLocation - the location of where the files should be cached queries. Defaults to /opt/VideoCache/.  'Note: the mediawiki user (such as apache) needs to have write permissions to this directory, and it needs to be created!

API
MediaWiki API calls added:

videocache-add

Parameters:


 * url - the url of the video, such as youtube.com/v=XXX. Can be any url that yt-dlp recognizes.
