'''Video Acceleration API''' ('''VA API''') is a royalty-free [[Application programming interface|API]] as well as its implementation as [[free and open-source]] [[Library (computing)|library]] (<tt>libVA</tt>) distributed under the [[MIT License]].

The VA  API interface is to be implemented by [[device driver]]s to offer end-user software, such as [[VLC media player]] or [[GStreamer]], access to available video acceleration hardware, such a [[Nvidia PureVideo|PureVideo]] or [[Unified Video Decoder]] and make use of it.

Some software may gain VA API support in the future : [[Lightspark]] (Flash / [[SWF]] player),<ref>{{en icon}} [https://bugs.launchpad.net/lightspark/+bug/859466 Bug report on Launchpad]</ref> and [[Xine]] (via "''xine-lib-vaapi''" library).<ref>{{en icon}} [http://old.nabble.com/VAAPI-support-for-xine-td32502350.html VA
