    Why couldn't thy use open standard for video acceleration like VA-API or something like this? Proprietary stuff is wrong in the linux world...

    at the moment VA-API is just a document dumped somewhere on freedesktop and inside some peoples brains. They might have used vaapi if it existed...

    For VA-API there is a plan. For their new acceleration mode there was no plan. They had to create it from the scratch. They could have use VA-API and improve it maybe. But they did not, because they don't want to help others.

    More like they can't be bothered to wait for the others to get their act together.

    exactly. Not to mention the fact that whatever changes they would request to vaapi would end up being discussed back and forth and probably go nowhere fast.

    Trying to implement an api which is currently quite nebulous, would inevitably require them to refactor/redesign again later, so why bother? Just design their own. Maybe later they can move to vaapi or create a wrapper lib (vid acceleration pipelines seem to generally be quite homogenous)...

    Default which hardware does this feature support?

    Can someone please point me to a list of exactly which NVidia hardware
    is supported by the new VDPAU feature?

    Thanks.

    Thanks.
    Here is the official list

    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
    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:



    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.

    Can you still use post-decode filters with this?
