Thread:Extension talk:TimedMediaHandler/Where to find mwEmbedSupport extension/reply

You can get mwEmbedSupport from the same parent directory as TimedMediaHandler: http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/MwEmbedSupport/

You need to setup the paths in the local settings for your encoder binaries see the README for more info

You may have some challenges running this off of a shared host because it includes transcoding support dependent on shell scripts / cron jobs.
