Default Video card suggestion for VDPAU?

My current video card is crapping out and I'd like to replace it with one that can decode Blu-Ray video including VC-1. I've read the announcement:

http://lists.freedesktop.org/archive...er/040279.html

and it looks like it may be G98 cards that can decode VC-1. Is that the case? If so, newer 8400 GS cards would work as well.

Can anyone recommend an inexpensive video card that can decode all Blu-Ray video and has no fan? I don't game at all.

Most nvidia/ati/intel marketing you see is focussed on Windows. On Windows DirectX multimedia streams pass through DirectX which in turn performs some parts the hardware doesn't offer in software. Geforce8/9 boards (except for the g80) have full h264 decoding support but they can only accelerate some parts of VC-1. Geforce 9400/9500 and some of the integrated geforce9 cards also offer VC-1 completely in hardware. Where on Windows DirectX can perform some parts in software VDPAU requires you to do it either fully in software or fully in hardware which means that for hw accelerated h264 and vc-1 decoding you need a geforce 9400 or 9500 (or one of the integrated versions).

lo

I bought an MSI card last week for 27 UKP that has a G98
and it has been tried and works with all VDPAU decoding
methods in the patched mplayer.

(II) NVIDIA(0): NVIDIA GPU GeForce 8400 GS (G98) at PCI:2:0:0 (GPU-0)
(--) NVIDIA(0): Memory: 524288 kBytes
(II) NVIDIA(0): GPU RAM Type: DDR2
(--) NVIDIA(0): VideoBIOS: 62.98.12.00.40

The card is advertised as an
MSI 8400GS 512MB DDR2 Heatpipe DVI VGA HDCP HDTV out PCI-E Graphics Card
and the model number is NX8400GS-TD512EH

BTW, I notice that the price has risen 10 UKP where I bought it.

As mentioned the 8400gt only offers h264 and not vc-1 using vdpau. Since he wants full blu-ray support he should buy a geforce 9400/9500 but those have about the same price as a 8400. A silent 9400/9500 is between 50 and 60 euro.

That card is a 8400 GS with a G98 GPU.

It works with mpeg, h264, wmv and vc-1 VDPAU decoding.

bye

Hmm, I didn't know about that. Guess wikipedia should be updated.

Does your g98 also offer HDCP support (nvidia sometimes uses the term PureVideo-HD in this context; PureVideo-HD cards also have enough bandwidth for 1080p)? Without encrypted blu-ray discs won't be playable in the future (though the Linux drivers don't offer this right now anyway and not sure if they ever will).

Hi

The card is marketed as HDTV Ready with HDCP support.

X gives us these details when attaching the flat panel:

(--) NVIDIA(0): Nexgen (DFP-0): 330.0 MHz maximum pixel clock
(--) NVIDIA(0): Nexgen (DFP-0): Internal Dual Link TMDS
(--) NVIDIA(0): Nexgen (DFP-0): Native FlatPanel Scaling is supported
(--) NVIDIA(0): Nexgen (DFP-0): DFP modes are not limited to 60 Hz refresh
(--) NVIDIA(0): rate
(--) NVIDIA(0): Nexgen (DFP-0): DFP is not internal to notebook

It only has a DVI out though.

Thanks wibble. I'm doing some research and it looks like 9400/9500 cards run much cooler than 8400 GS so I'll probably go with one of them.

Thunderbird, you mention 9400/9500 for VC-1, but the Nvidia announcement says 9300 GS, 9200M GS, 9300M GS, or GeForce 9300M GS. Are you sure about 9400/9500?

Hi.

CPUCoreTemp is around 55'C idle.

I replaced the glue they use with akasa thermal paste
and it now idles at 47'C. I have yet to do any proper
loading tests.

BTW, I neglected to mention two other things. The card
has an S/PDIF header but needs a proprietary DVI->HDMI
dongle which didn't come with the card.

It does come with two low profile brackets though, which
would allow splitting off the VGA either removing it entirely
else having it on a 2nd slot.

The 9400/9500 cards you mention are designated as G96
in nv4_disp.inf, whether they do VC-1 or not is unknown
to me at least.

Yeah, 9400/9500 isn't mentioned in the Nvidia announcement so I'm not sure why Thunderbird says they're capable of decoding VC-1.

lo

Actually, I did look around before getting this card. the key
seems to be `ModeVC1_VLD' support.

I don't think anything but G98 has it but I haven't bought
one of every GPU type to prove it.

Good luck!
