The API is called VDPAU (Video Decode and Presentation API for Unix). It provides a
large subset of PureVideo HD functionality for NVIDIA Linux, Solaris, and FreeBSD
The current API documentation is here:
Some highlights of VDPAU:
- Defines an API for GPU-accelerated decode of MPEG-1, MPEG-2, H.264, and
- Defines an API for post-processing of decoded video, including
temporal and spatial deinterlacing, inverse telecine, and noise
- Defines an API for timestamp-based presentation of final video
- Defines an API for compositing sub-picture, on-screen display,
and other UI elements.
Note that VDPAU does not address content protection.
Some highlights/limitations of NVIDIA's current implementation:
The VDPAU support in the NVIDIA 180.06 beta release is still very
preliminary. We are aware of cases of visual corruption and in some
cases GPU hangs. We will be working on these issues over the next
several NVIDIA driver releases.
While NVIDIA's VDPAU implementation is not ready for end user use yet,
it should be far enough along that interested application developers
can begin working with it.
Additionally, NVIDIA has developed patches to ffmpeg and MPlayer to
demonstrate a video player using VDPAU:
These patches include changes against libavcodec, libavutil, ffmpeg,
and MPlayer itself; they may serve as an example of how to use VDPAU.
Once we do some further testing, bugfixing, and cleanup, we will
contribute the MPlayer patches to the MPlayer developers.
If other hardware
vendors are interested, they are welcome to also
provide implementations of VDPAU. The VDPAU API was designed to allow
a vendor backend to be selected at run time.
VDPAU is currently supported on the following NVIDIA GPUs:
GeForce 200 Series
GeForce 9 Series
GeForce 86xx Series
GeForce 85xx Series
GeForce 84xx Series
GeForce 8300 GS
GeForce 8800 GTS 512
GeForce 8800 GT
GeForce 8800 GS
GeForce 8800M GTS
GeForce 8800M GTX
VC-1 support in NVIDIA's VDPAU implementation currently requires GeForce
9300 GS, GeForce 9200M GS, GeForce 9300M GS, or GeForce 9300M GS.
