    Not on r500 and earlier, which do not have a UVD unit. It's all done in shaders there.
    hd2900 and earlier this r600 card still do not have an uvd unit...

    means the catalyst driver supports h264 in shader.

      This is true for most cards that have an UVD unit. However as the 6770 is a rebranded Juniper, its UVD unit does not have the capabilities for MVC (Blu-Ray 3D) decode. So the decoding is done in the shaders.

        r300 also supported

        VDPAU/XvMC gallium 3d acceleration is also supported on r300 hardware now (commit).

        It is also available in my Ubuntu PPA.

          Wait, what? What does this buy us r300 users? Has somebody tested it?

            Yes. See http://phoronix.com/forums/showthrea...634#post211634

            EDIT: also note that r300 hardware means R300->R500.

                they buy an openGL2 card and can play openGL3 games unigine haven for exampel

                and now they do have video acceleration to... lucky bastards really...

                  But this is basically MC using the VDPAU interface, right? Most of the difficult parts of H264 are still not implemented, AFAIK.

                  Still very important, but not quite a fully accelerated shader solution just yet.

                    It currently implements iDCT and MC on the shaders.

                      Cool, so it's missing VLC and deblocking to support everything VDPAU offers, basically.

                      All of this is for Mpeg2 only atm, right?
