We are running a mediawikifarm (http://biowikifarm.net) on a debian system and have OggHandler installed. Uploaded Ogg-Videos work fine, except that the thumb normally shown before starting the video seem not to be created.
We have installed apt-get install ffmpeg ffmpeg2theora as requested.
Normal still image thumbs work fine. We are using http://www.mediawiki.org/wiki/Manual:$wgGenerateThumbnailOnParse = false, i.e. the thumbs are generated through apache rewrites to thumb.php. Working fine and wikimedia does it as well.
Does anyone had similar problem getting the still image thumbs for OGG videos to be generated? Any advice?
