    Err, yes it is? Wikipedia: "Most modern video controllers provide the functions required for XVideo; the feature is known as hardware scaling and YUV acceleration or sometimes as 2D hardware acceleration. "
    http://en.wikipedia.org/wiki/X_video_extension
    Edit: Oh, right. You meant as in decoding acceleration. Well, nice to see modern CPU's can actually do it with full quality with multithreading, I had to downscale playback quite a bit on my AMD64 3500+ to get it to work fluently.

If not, it might be worth staying on 8.10 until we finish QA testing & bug fixing on Jaunty, and announce support in the release notes.
      No, in Intrepid the Catalyst drivers were progressing nicely. But now with Jaunty they are a no-go. I though about going back to Intrepid but I have everything working nice in Jaunty except 3d so I am taking a break from gaming for now. Hopefully Catalyst 4.5 will soon fix the problem.

              Hey Alex,

              Thanks for the diff. I patched a fresh copy of the radeon-rewrite branch using what you just posted, and the Xv output is indeed improved, but there's still some cropping going on. I am seeing what looks like the upper-left quadrant of the video stream (using Miro to test using Xv output, M22 (x300 mobility), Ubuntu 9.04 w/ KMS/DRI2/etc), but the other 3/4 of the video are getting chopped off.

              I'll probably play around with the offset changes you had in your diff to see if I can get it to work on my machine, but no guarantees.

              --Aaron

                you'll also need to revert:
                8338385cd94b35f54b25cf2576890159f8dd9f71
                or just apply this patch:
                http://www.botchco.com/alex/xorg/kms_fix_xv.diff
                which contains both the reversion and the clipping fix.

                  Much better. The picture looks correct as far as I can tell. Xv is now usable, and much improved over having to set gstreamer to non-Xv output (was getting alternating smooth video and a slideshow watching videos earlier).

                  Thank you for the patch, and keep up the great work.
