    Default AMD's UVD2-based XvBA Finally Does Something On Linux

    Phoronix: AMD's UVD2-based XvBA Finally Does Something On Linux

    For a year now we have been talking about XvBA, which stands for X-Video Bitstream Acceleration and is designed to implement AMD's Unified Video Decoder 2 (UVD2) engine on Linux systems for improving the video decoding and playback process on desktop systems. AMD has been shipping an XvBA library with their ATI Catalyst Linux driver since last year, but they have yet to release any documentation on the XvBA API or any patches to implement the support within any Linux media players. Heck, AMD has not even officially confirmed XvBA with Phoronix being the lone source of information for the past year. Today though, XvBA has finally become useful under Linux. But it is not what you may be thinking...

    Any acceleration is better than none!

    Just UVD2? Why not UVD/UVD+ (R600)? The only difference I can tell from reading the wikipedia article is that UVD2 supports dual-stream decoding, which most people don't need or care about.

    only UVD2 has hardware HDCP Copyprotektion.. if they give some infos abaut uvd1 some people can hack the DRM Copyprotektion and the hd2000 VGA carts lost there Blueray hdready logo/funktionality..

    Hate to burst your bubble but HDCP support is not included with the XvBA library. Linux itself has no HDCP capabilities. It is not only the video that has to be protected.

    is not included yes.. but you can revers engenering the UVD funktionality !

    if you have any funktion on the uvd1 in use you can revers the copyprotection.

    why there are no specs for the uvd2 unit?? its only because if they push out specs they lost@copyprotektion

    Hey dont give us the infos for UVD2 the Blob work with UVD2 but it has no reasson why not on UVD

    realy ;-)
    When? what you mean with "older" cards? r300 up to r500?

    Maybe the radeon driver can utilize openCL for that task when its finally ported to gallium, but annyway that wouldnt be as fast as UVD and of course iam just guesing if this is really possible.

    But ok at least ATI released the specs for an oss driver which is more worth then some hd decoding which is something a modern cpu can do too.

    Older carts support focus on the opensource driver thats will be much more cost efficent for amd and for my point of view better for the linux users.

    hd2900 do not have a UVD unit 2900 has shader based viedeo acceleration.
    X1900 has shader based acceleration to.
    so yes its posible to bring portable shader based acceleration code to all card.
    older cards means hd2xxx and hd3xxx and some r500 like X1900
    i think the other cards are to old/bad...

    i think the catalyst/fglrx/UVD2 will be doomet by the opensource driver.

    first Dirac acceleration on opensource side will doom the UVD out..

    It's just good that it supports freedesktop.org's "standard" api for video accel VA-API will be highly likely get implemented more since more or less both amd and intel are supporting it.
