    Default A New Release Of The AMD XvBA Back-End To VA-API

    Phoronix: A New Release Of The AMD XvBA Back-End To VA-API

    Splitted Desktop Systems has updated their closed-source library that provides an XvBA back-end to a VA-API front-end so that those running the ATI Catalyst Linux driver are able to take advantage of the UVD2 video engine on newer Radeon HD graphics cards...

    All I can say about this is "Meh". This software is about as useful to Radeon owners as MS-DOS is to a Linux user.

    Not necessarily. There are Radeon-based netbooks that can't otherwise manage HD video. That said, I won't use it, since the open-source drivers do a better job of satisfying my needs. I really want to know when we can expect a VA-API state tracker for Gallium.

    By the time there are usable radeon Gallium drivers, VA-API will be completely obsolete, since there is a WIP VDPAU state stracker.

    I really couldn't care less about an nvidia technology like VDPAU.

    It really does not matter. VDPAU is designed to be a open API.

    VA-API is designed to be a generic API that can be backed by VDPAU or whatever.

    But if a VDPAU state tracker exists then that may just end up being a cleaner solution for everybody to use regardless of the video card.

    Ah, because you believe there is a WIP VDPAU state tracker implies that (i) the actual decoders are available, (ii) they are efficient and effective, (iii) magically support all other HW like ATI, Intel G45 and GMA500? The answer to all of those is "no". I don't see how the API can be obsolete when it has implementations for every single combined GPU+HW accelerator in Linux.

    don't expect to experience wonderful ATI video playback on Linux that's elegantly offloaded to the GPU in the manner that NVIDIA customers can with VDPAU and GeForce hardware.
    Why?

    While the solution may be not so good I actually can watch hd videos with < 10% CPU load extremely smooth...
    What can nvidia users with vdpau do that I can't?

    Anyone know if it finally has support for profiles L@5.1?

    Most of the work to create a VDPAU state tracker would be in the video decoding routines. Once someone's written the shaders and SSE code required, it should be relatively simple to wrap it up in either VDPAU or a VAAPI state tracker.
