DirectX Video Acceleration
open-in-new
<p>DirectX Video Acceleration (DXVA) is a <a href="/facts/Microsoft/nGIDDXdx">Microsoft</a> <a href="/facts/API/GMlN4vUr">API</a> specification for the <a href="/facts/Microsoft_Windows/bwhAhuSL">Microsoft Windows</a> and <a href="/facts/Xbox_360/dYlE3mL5">Xbox 360</a> platforms that allows <a href="/facts/Digital_video/xsn9omqG">video</a> <a href="/facts/Codec/C7b7Am8t">decoding</a> to be <a href="/facts/Hardware-accelerated/ej5sM7hB">hardware-accelerated</a>. The <a href="/facts/Pipeline_(software)/vNahQdsH">pipeline</a> allows certain <a href="/facts/CPU/Jxp1bqMV">CPU</a>-intensive operations such as <a href="/facts/Inverse_discrete_cosine_transform/gPpDhPwP">iDCT</a>, <a href="/facts/Motion_compensation/6BM2Ylxn">motion compensation</a> and <a href="/facts/Deinterlacing/zIvhUYdG">deinterlacing</a> to be offloaded to the <a href="/facts/GPU/PTK1RQVp">GPU</a>. DXVA 2.0 allows more operations, including <a href="/facts/Video_capturing/D4HgJ7As">video capturing</a> and <a href="/facts/Video_processing/n08sasRV">processing</a> operations, to be hardware-accelerated as well. </p><p>DXVA works in conjunction with the <a href="/facts/Video_renderer/EcgkCLxy">video rendering</a> model used by the <a href="/facts/Video_card/bcKfPyFt">video card</a>. DXVA 1.0, which was introduced as a standardized API with <a href="/facts/Windows_2000/amJIt9gz">Windows 2000</a> (<a href="/facts/DirectX_7/jyy75wVN">DirectX 7</a>), and is currently available on <a href="/facts/Windows_98/6qtq4oJm">Windows 98</a> or later, can use either the <a href="/facts/Video_overlay/4nyIpjmM">overlay rendering mode</a> or <a href="/facts/Video_Mixing_Renderer/d7dPeQ5W">VMR 7/9</a>. DXVA 2.0, available only on <a href="/facts/Windows_Vista/IASEUCTB">Windows Vista</a>, <a href="/facts/Windows_7/tldLdbnX">Windows 7</a>, <a href="/facts/Windows_8/eRtw96T3">Windows 8</a> and later OSs, integrates with <a href="/facts/Media_Foundation/KNcV7zX0">Media Foundation</a> (MF) and uses the <a href="/facts/Enhanced_Video_Renderer/KNcV7zX0">Enhanced Video Renderer</a> (EVR) present in MF. </p>
