    Default No hardware video acceleration from ATI - ever?

    My email, and answer from ATI:

    Subject:
    "vdpau"

    Category:
    GPU Tools

    Sub-Category:
    Graphics Driver Developers

    Status:
    Pending

    Ticket Details:

    I'm very dissappointed that there is no support for vdpau (or similar) for your gpu's in f.eks XBMC. I just bought a ATI HD card, but it now turns out to be a was a waste of money. I can't play h264 files with any hardware support from the gpu. Fortunately the card was cheap. I have always gone for ATI cards, but in the future will go for Nvidia if you don't go for open source code and let developers take advantage of the potential in the gpu.

    No plans to support it now or in the foreseeable future as there was no interest from selected ISVís working on such projects.

    Keep in mind that emails like that could be fielded by someone who knows almost nothing about their linux drivers or linux in general, someone who mostly deals with Windows gamers and OEMs.

    I had to google XBMC to find out it stands for XBox Media Center. They probably had to look up or ask about "vdpau", and were informed that it was an nVidia thing.

    Perhaps the "it" in the reply refers to vdpau, not hw accelerated video playback with open source drivers.

    Independent software vendor, i.e. a company that is interested in making a video player/encoder/whatever using vdpau (or ATI own library).

    This is a very strange email.

    ATi DOES support full decoding acceleration on their cards -- on Windows. You didn't even mention Linux in your email.

    Then you threaten to buy nVidia if ATi doesn't " go for open source code and let developers take advantage of the potential in the gpu". But nVidia hasn't made anything available as open source, least of all hardware decoding.

    The situation regarding hardware decoding on Linux with ATi cards is rather unfortunate at the moment, but if you are praising nVidia, then you should be asking for a binary blob decoder, like the one from nVidia. ATi is doing far more for open source than nVidia.

    I'm not very into this, but on my XP machine there is no ATI gpu-hardware acceleration of videofiles in any software (Xmbc, Vlc). Yes there is for Blueray disc, but that's not what primarily i'm after. As far as I know (from Googling) the situation is the same for Ubuntu.

    I have a Acer Revo with Intel Atom and Nvidia Ion and with vdpau activated in Xmbc it plays 1080p files smoothly. That's what I want from my ATI card...

    Peace

    You need to use a player that uses DXVA to use UVD on Windows.

    http://mpc-hc.sourceforge.net/ does, although I have found some H264 broadcast streams that don't work. I don't have a clue if it's the player, DXVA, the drivers or UVD on my card that's the problem. Most H264 seems to work - the ones that didn't were 1088x1920 so maybe that confused things.

    As for OSS, UVD may be out of question, due to HDCP, but the devs have already said that there is enough info out for 3D engine GPU assisted decoding, just no one has written it yet.

    In fact if there are UVD limitations to precise stream types, using the 3D engine may end up being a better and more flexible solution.

    Under Windows XP,you need to use a player that uses DXVA to use UVD on Windows.

    DXVA for H.264 and VC-1 videos *doesn't work* under WinXP.

    I've tried all existing players for Windows (PowerDVD, MPC-HC, KMPlayer, WMP) with all video renderers (Overlay Mixer, VMR7, VMR9, EVR), but nothing works with the Radeon HD 2600

    There's no HD video acceleration under WindowsXP for ATI cards.

    I don't need BluRay acceleration, I only need video acceleration for normal H.264 videos (free / open-source 1080p HD clips / trailers / videos you can download from the net).

    Take the Elephant's Dream 1080p video as an example:
    http://showcase7.divx.com/ElephantsDream[DivX7].mkv

    That video is so demanding that it's impossible to play it on a machine with a (relatively powerful*) single core CPU.

    * not an Atom or Sempron
