xf86-video-ati 6.10.0 Released

Run

xrandr

to see it flicker

[curaga]

Compared to rc1 I have some flicker when X starts and it also starts slower. Haven't yet tried to watch videos.

X1300 Pro (Rv516)

The Xv code is next on the list now that Alex has the 780 IGP parts working. We're still trying to figure out why the YUV-to-RGB shader for 6xx/7xx works in the test program but not in the driver code.

Thanks for the prompt answer

Did they make xv work at all in r700 (HD4850)?

Still tearing with the privative drivers .

[NeoBrain]

can someone explain what is forth bi-cubic scaling?

thanks

ps: actually, what does this support mean in a normal day usage?

"to bring forth" is an English phrase that means something about the same as only "to bring" :P
(Well, the explanation could be a bit better, but you get the point)

bi-cubic scaling improves the picture quality when e.g. playing movies by using mathematical algorithms.

EDIT: ok, bridgman was faster

I think this is talking about bicubic filtering in Xv. Whenever the driver displays video at a different resolution from the recording (eg when you are playing full screen or a big window) it uses the GPU to scale up the frames.

If you don't filter while scaling you get big scaled up pixels in the displayed video and it looks crappy, so you have to filter. Bilinear filtering (the default for most HW, I think) gives you a slightly blurry image; bicubic filtering takes more processing but gives you a sharper image while still getting rid of the jaggy scaled up pixels.

Phoronix: xf86-video-ati 6.10.0 Released

AMD's Alex Deucher has announced the release of the xf86-video-ati 6.10.0 driver. This open-source ATI graphics driver update brings forth bi-cubic scaling on R300/400/500/690 chipsets, new ASICs are supported by this DDX driver, reduced X-Video tearing, and quite a few bug-fixes. The whole list of changes found in xf86-video-ati 6.10.0 can be read on the X.Org mailing list...
