 For encoding and decoding support, you should install {{{libvpx}}}.
+You will need libvpx 1.4 for full VP9 support.
 
 For decoding support only (client) it is possible to use the {{{dec_avcodec}}} or {{{dec_avcodec2}}} modules if [http://www.ffmpeg.org/ ffmpeg] (or [http://libav.org/ libav] if you use this fork) were built with vpx support.
