    Default AMD Opens Up XvBA! Their Catalyst Linux Video API

    Phoronix: AMD Opens Up XvBA! Their Catalyst Linux Video API

    Back in 2008 we were the first to thoroughly talk about AMD's X-Video Bitstream Acceleration (XvBA) API found in their Catalyst Linux driver to expose their UVD2 video engine now under non-Windows operating systems. However, when the XvBA library was made available, it was next to useless since they hadn't published the documentation or any header files describing this video playback acceleration interface. A year later, in November of 2009, AMD and Splitted Desktop Systems released a VA-API front-end to XvBA so that VA-API multi-media applications could seamlessly use XvBA with the Catalyst driver...

    Nice move, but I can't see many video players supporting this... VA-API directly would be the best (VLC).

    See, this is why I didn't even look at Nvidia when I was looking for a new graphics card. (And, I'm encouraging others to buy AMD, too.)

    Although I must admit, I'm buying it used, unless someone wants to give me the additional $30 for a new card.

    Wouldn't VA-API just wrap XvBA? I think that's what they're doing for VDPAU on Nvidia.

    at least their still behind

    It's nice to hear good news about AMD Linux development too once in a while., although it's just partially good news because DRM is ruining the fun again.

    At least now everyone can see for themselves if the api is as horrible as gbeauche has implied.

    And I will let people try to write a player from scratch with only the header file and doc file, without cheating and looking at demo code and realize the particular things to adjust...

    This feels more like a move from AMD to address a key deficiency on Linux for their Fusion lines...Both the E-/C-series (Zacate/Ontario) and the upcoming A-series (Llano) are pretty much ideal for their respective markets; given their reasonably capable GPU-based IGP.

    If they can get their A-series working with accelerated video playback on Linux; I'm pretty much sold for the K10.5-based "Llano" (2011) and Bulldozer-based "Trinity" (2012).

    ...I'm not all that enthusiastic about buying a discrete video card when I don't have to. I've seen leaked slides that indicate that the A-series (Llano) IGP performs like a Radeon HD 5550 GPU. (It meets my computing needs.)

    it's more than just 'This feels like', it probably is a key part of 'the man with the plan' ,
    however in this case it doesn't seem to be bridgman , rather Tim Writer ECSD Liaison Engineer at AMD, Owner at SaaS 44 Inc. whoever he is ?

    http://techreport.com/articles.x/20401/1
    "...
    there's the fact that AMD made us do it. You see, back when the firm revealed the first details about the Bobcat CPU architecture used in Brazos, it predicted Bobcat would achieve an "estimated 90% of today's mainstream performance in less than half the silicon area." Now, such statements are famously slippery, but those words did conjure up some rather dreamy expectations inside of our heads. We likened Bobcat's potential performance to 90% of the Athlon X2 255's...."

    and they clearly expect a lot from the UVD3 inside that latest AMD E-350 Zacate even though they are windows only testers, no one seemed to have the heart to tell techreport that UVD (other than gbeauche's valiant but limited success with a few UVD combinations OC) doesnt work to well for your basic high profile decode assistance in linux OSS...

    Yeah. I was looking to upgrade my HTPC recently, and was very excited about Sandy Bridge as an all-in-one solution, but I ended up being extremely disappointed with the product delivery (must have K series to get best graphics core, must use H series M/B to use best graphics core, must use P series for K series processor to make any sense--duh, way to go Intel). I ended up going with an nvidia 9300 chipset and a core2. The 9300 wasn't quiiiite fast enough for what I needed so I also used a discrete gf240.

    I'm very pleased with the results, however sometime this summer or fall I'll probably be looking at building two mythfrontend-only machines, and this development means I'll be looking very seriously at Llano as a solution. Bravo AMD.
