'''Video Acceleration API (VA API)''' is an [[open source]] software [[Library (computing)|library]] ("''libVA''") and [[Application programming interface|API]] specification. The [[cross-platform]] API enables and provides access to hardware accelerated video processing, using hardware like for example [[Ggraphics processing unit|Graphics Processing Unit]]s (GPU)]] to accelerate video processing in order to offload the [[Ccentral processing unit|CPU (Central Processing Unit)]]]] (CPU) to decode and encode [[Data compression|compressed]] [[digital video]].

VA API video decode/encode interface is platform and window system independent but is today primarily targeted at [[Direct Rendering Infrastructure|DRI (Direct Rendering Infrastructure)]]]] (DRI) in [[X Window System]] on [[Unix]]-based [[operating system]]s (including [[Linux]], [[FreeBSD]], [[Solaris (operating system)|Solaris]]), and [[Android (operating system)|Android]], however it can potentially also be used with direct [[framebuffer]] and graphics sub-systems for video output. Accelerated processing includes support for [[Video codec|video decoding]], [[video coding|video encoding]], subpicture blending, and rendering.<ref>http://www.phoronix.com/scan.php?page=news_item&px=MTA0NDI(contracted; show full)
