Developers from NVIDIA presented the open library libvdpau 1.5 with implementation supporting the VDPAU (Video Decode and Presentation) API for Unix-like systems. The VDPAU library makes it possible to use hardware acceleration mechanisms for processing video in h264, h265, VC1, VP9 and AV1 formats, and offload tasks such as post-processing, compositing, display and video decoding to the GPU. Initially, the library supported only GPUs from NVIDIA, but later support for open drivers for AMD cards appeared. The libvdpau code is distributed under the MIT license.
In addition to bug fixes, libvdpau 1.5 introduces support for accelerating video decoding in the AV1 format, and also adds tracing tools for VP9 and HEVC formats. The AV1 video codec was developed by the Open Media Alliance (AOMedia), which represents companies such as Mozilla, Google, Microsoft, Intel, ARM, NVIDIA, IBM, Cisco, Amazon, Netflix, AMD, VideoLAN, Apple, CCN and Realtek. AV1 is positioned as a publicly available, royalty-free free video encoding format that is noticeably ahead of H.264 and VP9 in terms of compression levels.
