Nvidia显卡 视频硬件解压 最新信息 -英文

Nvidia have annonced a new video API for Unix and Unix-like platforms today, the preview technology implement hardcore API named VDPAU (Video Decode and Presentation API for Unix) large subset of PureVideo HD functionality for NVIDIA Linux, Solaris, and FreeBSD users.

The most recent API documentation state:
A download Link:

ftp://download.nvidia.com/XFree86/vd...tml/index.html

VDPAU feature details:

* 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.

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
http://www.nvidia.com/object/freebsd_180.06.html
http://www.nvidia.com/object/solaris...ay_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.



VDPAU is currently supported on the following NVIDIA GPUs:

Desktop 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

Mobile GPUs:
GeForce 98xxM
GeForce 9700M
GeForce 96xxM
GeForce 9500M
GeForce 9300M
GeForce 9200M
GeForce 8800M
GeForce 8800M GTS
GeForce 8800M GTX
GeForce 8600M
GeForce 8400M

Motherboard GPUs:
GeForce 9400
GeForce 9300
GeForce 9100
GeForce 8300
GeForce 8200

VC-1 support in NVIDIA's VDPAU implementation currently requires GeForce
9300 GS, GeForce 9200M GS, GeForce 9300M GS, or GeForce 9300M GS.

我想就是ATI也不会对高清部分开放源代码把。我多么期待我的A卡用开源驱动也可以硬解一下,avivo开源驱动什么时候。。。。。貌似windows下ATI的UVD更强把。
