# VDPAU
VDPAU is the Video Decode and Presentation API for UNIX. It provides an interface to video decode acceleration and presentation hardware present in modern GPUs.
## Features
* Hardware decoding of MPEG-1, MPEG-2, MPEG-4 part 2, H.264, VC-1, and DivX 4 and 5 bitstreams on supported hardware, with a bitstream (VLD) level API.
* Video post-processing including advanced deinterlacing algorithms, inverse telecine, noise reduction, configurable color space conversion, and procamp adjustments.
* Sub-picture, on-screen display, and UI element compositing.
* Direct rendering timestamp-based presentation of final video frames, with detailed frame delivery reports.
## Documentation
Documentation for the API is stored in Doxygen comments in the VDPAU header files. You can also read the [[generated HTML version|https://vdpau.pages.freedesktop.org/libvdpau/]].
## Code
The library used by applications that wish to use VDPAU is [[libvdpau|https://gitlab.freedesktop.org/vdpau/libvdpau]]. This is a wrapper library that loads the appropriate implementation backend. There is also a tracing library that can be used to debug VDPAU applications.
