'''Video Acceleration API''' ('''VA-API''') is aan royalty-free[[open source]] [[Application programming interface|API]] that allows applications such as [[VLC media player]] or [[GStreamer]] to use hardware video acceleration capabilities, usually provided by the [[graphics processing unit]] (GPU). It is implemented by the [[free and open-source]] [[Library (computing)|library]] <tt>libva</tt>, combined with a hardware-specific driver, usually provided together with the GPU driver.

VA-API video decode/encode interface is platform and window system independent but is primarily targeted at [[Direct Rendering Infrastructure]] (DRI) in [[X Window System]] on [[Unix]]-like [[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 name="ReferenceA">{{cite web|url=https://www.phoronix.com/scan.php?page=news_item&px=MTA0NDI|title=VA-API Video Acceleration On Intel Medfield - Phoronix|website=Phoronix.com|accessdate=23 February 2019}}</ref>
