Movhandler is a project mainly written in PHP, it's free.
Mediawiki extension to handle quicktime movie (mov) files. Produces a thumbnail for image galleries etc.
Once installed, extension will automatically make thumbnails for uploaded quicktime movie (.mov) files. You can also embed thumbnails for movie files as you would images, just specifying the .mov file instead. e.g.
[[Image:mymovie.mov|200px]]
E.g. on ubuntu type:
sudo apt-get install ffmpeg imagemagick
Put the downloaded files into the extensions/movhandler/ directory off your mediawiki installation, then add the following to LocalSettings.php:
require_once("$IP/extensions/movhandler/movhandler.php");
You may also need to add '.mov' to the allowed filetypes.
