| − | ==What is it==
| |
| − | he 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
| |
| − | users.
| |
| − | | |
| − | The current API documentation is here:
| |
| − | | |
| − | ftp://download.nvidia.com/XFree86/vd...tml/index.html
| |
| − | | |
| − | Some highlights of VDPAU:
| |
| − | | |
| − | * Defines an API for GPU-accelerated decode of MPEG-1, MPEG-2, H.264, and
| |
| − | VC-1 bitstreams.
| |
| − | * Defines an API for post-processing of decoded video, including
| |
| − | temporal and spatial deinterlacing, inverse telecine, and noise
| |
| − | reduction.
| |
| − | * Defines an API for timestamp-based presentation of final video
| |
| − | frames.
| |
| − | * 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:
| |
| − | | |
| − | * Supported on NVIDIA GPUs with the NVIDIA second generation video processors
| |
| − | (see the end of this announcement for a complete GPU list).
| |
| − | * Currently, only one video stream can be decoded at a time; we hope to lift this
| |
| − | restriction eventually.
| |
| − | * Available in the 180.06 NVIDIA public beta release:
| |
| − | http://www.nvidia.com/object/linux_d...32_180.06.html
| |
| − | http://www.nvidia.com/object/linux_d...64_180.06.html

| |
| − | | |
| − | | |
| − | 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:
| |
| − | | |
| − | ftp://download.nvidia.com/XFree86/vd...076399.tar.bz2
| |
| − | | |
| − | 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.
