  • never mind

    ok never mind, I finally got it working. Using xbmc with vaapi acceleration. the image is very distorted though, is this to be expected?

      ok I fixed the distorted image by using catalyst 10.12. The picture is now very clear. It is working perfectly in mplayer with vaapi but it is stuttering a lot in xbmc. dunno how to fix this?

        ok could fix this with a patch to xbmc:
        wget http://trac.xbmc.org/raw-attachment/...ce_reuse.patch
        patch -p0 vaapi_surface_reuse.patch

          thanks for the reply! so, i used the PPA that's mentioned in the wiki you linked, and installed libva and vlc from it, with the xvba-backend from the splitted desktops site. it works fine on "ordinary" movies, but when i try an HD movie it just freezes the computer completely. i have to switch it off. this happened in my previous attempts too (i've managed to install the libva from the splitted desktops site, and compile the mplayer given there, to get the same freeze effect).

          the wiki says that UVD support was broken in the new Catalyst drivers and that 10.7 is the last version of the drivers that works on non-UVD2 cards. i have a mobility radeon HD 3470, that's just UVD+, so that might be the case for me too?

          i've downloaded Catalyst 10.7, but the installer just crashes when started without args. i managed to build packages for maverick, and installed them, but X would no longer start after rebooting. what can i do now?..

            Thanks! This solved all problems that - I thought- had to do with not fully matured VAAPI support on AMD's side (never bothered to look if it had anything to do with XBMC).

            I used:
            Catalyst 11.1
            And from gbeauche:
            libva1_0.31.1-1+sds5 (dated 26 jan 2011)
            xvba-video_0.7.8.pre1-1 (dated 26 jan 2011)

            Everything plays very smoothly with full HW acceleration now .

            But I noticed a few things that I would've hoped to have been solved by now:

            Sometimes switching to (and from) movies in xbmc there is garbled output for a (very) short moment. Sometimes just before the movie starts, sometimes after quitting a movie and returning to the xbmc interface. Also sometimes starting xbmc from within Ubuntu. Could this this be related to resolution changes, as I think I've read somewhere on the xbmc forum?

            And also:
            I have a HD5550 card, that supports UVD 2.2. Now it could be me but I believe that UVD 2.x supports MPEG2 HW acceleration?



            But nope, it is not there:



            And indeed, upon checking:

            Code:
            vainfo: VA API version: 0.31
            vainfo: Driver version: Splitted-Desktop Systems XvBA backend for VA-API - 0.7.8.pre1
            vainfo: Supported profile and entrypoints
                  VAProfileH264High               :	VAEntrypointVLD
                  VAProfileVC1Advanced            :	VAEntrypointVLD
            Is this normal? Or is it still on its way?

            In summary I see VAAPI support almost as usable now under XBMC (except for the resolution switch problem, at least that seems to be the problem -as I seem to understand- related to the short garbled moments I see, on swithing between content and GUI).

            • Mpeg2 is only accellerated with Intel or Nvidia.

                Likes to crash a lot on exiting/reentering xbmc though.

                • I am planning to buy a zacate motherboard with E-350 for a HTCP. I would like to know if the hardware acceleration works and how well (especially with mythtv). It seems that mythtv will support vaapi in the future 0.25, but would I be able to use it now if I patch/compile? Also is the hardware acceleration as a good as nivdia ion?

                  • I see the point of that, Zacate Hardware is very nice, but if you want a stable HTPC on linux, run (to nvidia) while you can.
