= vpx: VP8 and VP9 Encoder =
The vpx codec supports both VP8 and VP9 formats.

[[BR]]
Please also note that VP8 currently only supports {{{YUV420P}}} colour subsampled data, which leads to some visual degradation, especially with text.
}}}


{{{#!div class="box"
== Build and installation ==
When building xpra from source, {{{vpx}}} support is included by default.

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.
