    Interesting. Obviously we should be using floating point
    to describe this. UVD1.998 vs. UVD2.002 :-)

    But the real question is when will we be able to decode
    video using some variety of UVD and FLOSS-only software
    (binary-only blobs are not acceptable)? A solution that
    only supports UVD 3.x and newer is probably ok. Mpeg2
    is sufficient, I don't need every obscure codec in the book.

    The day I read about this working is the day I start
    shopping for an ATI GPU.

      In principle never, unless somehow somebody manages to decouple the DRM protected bits from the rest--if I'm not mistaken. On top of that, apparently the OSS developers are not particularly interested on this area, be it because there isn't any monetary incentive, because of codec patents (go figure), and because you know, the majority of linux users only watch pirated movies anyway.

        2 points

        first point Buy a R900 based card in the end of 2011! R900 will have opensource support for the viedeo acceleration unit...

        second point the opensource driver for r600+/r800 will never use the UVD2 unit NEVER! but there will be a pure shader based viedeoacceleration.
        This version will save you 50% of the needed cpu "power" (uvd2 can reduce the cpu usage up to 95%)

        "The day I read about this working is the day I start

        really? Buy it now! the shader based version will come to the opensource driver be sure!

          Thank you all for the useful posts esp Bridgman. I will wait for the shady er shader business to complete. When is the ETA for this? Can we expect this in Ubuntu 9.0,4 final?

          TIA
