i'm trying to build a CHEAP universal-video player,something like a simple mediacenter.i'm wondering how would be a minimum configuration to play fluently every kind of video,including 1080p(h264,vc1 or whatever).what are minimum cpu and graphic card required to play everything smoothly?

Hard to say...

GPU acceleration has gotten very good recently with MPC - Home Cinema's special decoder.

If you want to rely on that, then any processor (maybe a low end E2xxx series processor), an 8500/8600gt or 2400/2600 pro for the video card, and at least 1 gb of ram - preferably 2.

That should handle just about everything. Get a stronger CPU if you're paranoid. E6750 should handle _everything_ in pure software, worst case.

the thing about that is that theres still a lot of old broken spec streams
and not everyone is willing/can recode them to be compliant

so I'd fall back with a mid end dual core and maybe coreavc, its pretty cheap still
and that should be able to handle any of the non-acceleratable encodes

of course its looking like DXVA2 might be capable under XP soon if ATI/nvidia enable it in their drivers, but I wouldn't count on it till more info is released

Interesting.

I would imagine that most of the broken spec streams "floating around" aren't as demanding as (for example) at 25mbps H.264 stream from a BluRay disc.

In any case, CoreAVC was able to handle 10-12 mbps H.264 just fine on my 3800+ X2, so any Core 2 Duo should handle things pretty well.

according to some talk in the coreavc forum a month or two ago some BDs had out of range motion vectors so thats something to watch out for as well

Interesting. Hopefully the DXVA decoders will improve a bit :)

well they can only decode what the UVD can handle
and they can't handle broken spec all that well
as they shouldn't have to...

is linux better(lighter for hardware) for playing video?would it help on a slow hardware?

not really
AVC just takes A LOT of resources to decode
a decent dualcore will be able to do it

and depending on the pricing of it it might be worth the wait for those tri-cores
they should be able to handle it easy

Hi,

how do I know if DXVA is really working, can I see that anywhere? I have a Geforce 8800GT.

Thanks

open up the task manager (ctrl+shift+esc)
if its not using a bunch of your CPU and is using like 0-6% then you're on DXVA

There may be a log file called dxva.log around somewhere. On my system, it's C:\dxva.log...

I notice that WPM creates that automagicly when ever you open a wmv file in current directory

that'd explain the 0 in it

If DXVA is enabled and working, it'll either say "Index control class freed", or 0. If it's not working properly, there'll be a ton of errors. ;)

Hi,

I don't have a dxva.log file, and my CPU usage doesn't change, no matter if I set Direct X Accelleration in WMP11 or not. I have the latest Forceware driver installed, how can I examine what's going wrong? Is there a diagnostic tool?

then you don't have acceleration
or you can't accellerate that file
