The only think to consider is that if bicubic filtering is enabled then these new attributes won't be available. Here's the latest I could find on turning bicubic off -- looks like it's controlled by *another* attribute :
"You can disable it on the fly using the XV_BICUBIC Xv attribute. You can use an app like xvattr to change Xv attributes."
Last I remember is that bicubic is enabled by default on 3xx-5xx hardware. I'm pretty sure about 5xx, less sure about 3xx-4xx.Test signature

What it's not is video-decode acceleration.
btw, great work @ all involved

Wierd... my experience has been exactly the opposite... I don't think I've ever seen "video acceleration" refer exclusively to decode.
VDPAU, VA-API and XvBA are all decode+render APIs.
Maybe you're thinking about it from a "news" perspective ? If render acceleration was already available, and then decode+render acceleration is announced, the "new part" is decode ?Test signature

Yeah, I was just looking in the tree and it seems Roland started with 2xx, not 1xx. I just asked agd5f for clarification on IRC..
OK, that was a D'oh!! moment... the attribute processing is done in shaders, and the R100 family doesn't really have what we call shaders today.Last edited by bridgman; 19 April 2009, 01:19 PM.Test signature
