I recommend using the static binaries hosted on firefogg or if you want to compile it your self using the build tools provided there: http://firefogg.org/nightly/
Also I would suggest you take a look at TimedMediahandler as an alternative to oggHandler it has a lot more features such as WebM, timed text, and transcoding support. http://www.mediawiki.org/wiki/Extension:TimedMediaHandler A live install is on prototype if you want to play around with it: http://prototype.wikimedia.org/tmh/ If you run into any issue, please report them on the bug tracker or directly to me. https://bugzilla.wikimedia.org/enter_bug.cgi?product=MediaWiki%20extensions&component=TimedMediaHandler peace, --michael On 07/08/2011 04:18 AM, Dmitriy Sintsov wrote: > Hi! > > What's the proper way of thumbnail generation for Ogg media handler, so > it will work like at commons? > > First, I've downloaded and compiled latest ffmpeg version (from > git://git.videolan.org/ffmpeg.git) using the following configure > options: > > ./configure --prefix=/usr --disable-ffserver --disable-encoder=vorbis > --enable-libvorbis > > The prefix is usual for CentOS layout (which I have at hosting) and best > options for vorbis were suggested in this article: > http://xiphmont.livejournal.com/51160.html > > I've downloaded Apollo_15_launch.ogg from commons then uploaded to my > wiki to check Ogg handler.
