![]() Ĭurrently, the portions capable of being offloaded by VDPAU onto the GPU are motion compensation (mo comp), inverse discrete cosine transform (iDCT), VLD (variable-length decoding) and deblocking for MPEG-1, MPEG-2, MPEG-4 ASP (MPEG-4 Part 2), H.264/MPEG-4 AVC and VC-1, WMV3/ WMV9 encoded videos. VDPAU allows video programs to access the specialized video decoding ASIC on the GPU to offload portions of the video decoding process and video post-processing from the CPU to the GPU. ![]() VDPAU is targeted at Unix-like operating systems (including Linux, FreeBSD, Solaris). The VDPAU interface is to be implemented by device drivers, such as Nvidia GeForce driver, nouveau, amdgpu, to offer end-user software, such as VLC media player or GStreamer, a standardized access to available video decompression acceleration hardware in the form of application-specific integrated circuit (ASIC) blocks on graphics processing units (GPU), such as Nvidia's PureVideo or AMD's Unified Video Decoder and make use of it. ![]() Video Decode and Presentation API for Unix ( VDPAU) is a royalty-free application programming interface (API) as well as its implementation as free and open-source library ( libvdpau) distributed under the MIT License.
