Nvidia GeForce GTX 460(GF104 GPU) supports full audio bitstreaming - Page 12

I tried both ffdshow_rev3342_20100331_clsid and ffdshow_rev3529_20100811_clsid, both from sourceforge. I used all default settings except enabling passthru of truehd and dtsma. I have 2 mkvs, one each with truehd and dtsma. I tried both in graphedit with mpc-hc mkv splitter and latest haali, and all kinds of audio renderers: nvidia wav and directsound, cyberlink 8 and 10, Arcsoft from TMT3, reclock with directsound, wave, and wasapi, and mpc-hc audio renderer.

I can get ffdshow to say that it is bitstreaming with some of those, but the receiver says no signal and I either get no sound at all, or static. My receiver is an Onkyo TX-SR705 and my vid card is EVGA 1GB 460GTX with the only version of driver available from Nvidia.

I really don't want to upgrade the machine to Win7. As silly as it sounds, one of the primary uses of the PC is the photos screen saver that comes with Vista. We use it to play our photos and videos all the time. The kids love seeing that on the wall in the family room. The windows live essentials version, the only one available for Win7, won't play full videos, only the first 10 seconds.

Thanks

EXPreview: NVIDIA GeForce GTS 450 Review Leaked

VR-Zone


GT 430 will be the most interesting product (from NVIDIA) for HTPC users.

It doesn't matter if they did or not really. If it's not defined in the Windows ks.dll, renderers and decoders can define it in their own code (and the output device driver would need to support it). You would just need a renderer and a decoder that had it defined and use them in combination with each other.

what you mean by that..> referring to money save than other competitors do like gts450 , or in you mean difference in PQ which I think both have pure video.

96 stream processors is usually enough for good video post processing. 192 of GTS 450 is a waste for video playback. GTS 450 also requires an external power connector, that many people hate. HQV 2.0 scores.

- GT 220: 48 sp
- GT 240: 96 sp
- GT 9800 GT: 112 sp

PureVideo HD consists of a hardware decoder (for MPEG-2/VC-1/H.264/MPEG-4 Part 2/MPEG-4 MVC) and video processing by stream processors/driver. Lack of enough stream processors and often memory bandwidth will result in poor decoding/video processing, while an excessive number of stream processors is a waste of money/power consumption.

If I am building HTPC eather way i3 or i5 (with gt450 or gt430) and my use is watching heavy movie 1080p for example 30gb (I know that i3 is fear enough for my use) but if my uses include Internal blu-ray player and my goal is to have best picture qaulity I can get frome the blu-ray player ,so which I have to focus on CPU or GPU cause in case of internal BD the processing goes on sholder of GPU or CPU..?

note# (I have standalone BD it's oppo bdp-83) but just want to see if there will be any upgrade in PQ (I belife in hardware could cause difference)

Playing 1080p movies (including the majority of BD movies) is the easiest among all video playback tasks, and nowadays any graphics card (AMD, NVIDIA or Intel) can do it with a very good result, comparable with a standalone BD player.

link was so helpfull , thanks

really appreciate it.

Hi all,
Let me jump in here and ask a question.
I currently have a XFX Radeon HD5770 in my HTPC.
I also have a couple of weeks left before my Best Buy 90 day return time limit is reached.
I was checking out some reviews of the EVGA GTX 460 1GB version card.
Is the consensus in here that I am better off staying where I am with my 5770?
I have not had any problems with my 5770 and I do not really Game, more Surf and Blu-Ray.

Thanks to all,
Bud B

Since your HTPC needs are meet with the current card, I don't see the point of upgrading to a better card.

Since you're not really interested in PC gaming... Don't do it!
I had the same dilemma, but I'm interested in good SC2 performance and the 5770 didn't have enough power to max out SC2 and maintain good framerates with multiplayer while my 460 can. My beef with the 460 is still the lack of a working PAP Bitstream driver. ATI's PAP Bitstreaming works for most at this point since they've had almost a year to perfect it. Honestly, since this is not my main gaiming rig, if I could do it all over again I would've saved the $50 and kept the 5770. For your case even a "lowly" 5550/5570 card is more than sufficient (as for htpc duties a 5550 makes no difference vs a 2x as expensive 5770) and you can get one without a fan even.

Thanks for the response guys,
We can all be guilty of tweaking more than it is sometimes worth and shooting ourselves in the foot.
That's why I wanted to ask about the 460 and my 5770 to put it in perspective.
Was it really worth all of the work involved to pull out and return my 5770 and order a 460, and redo everything, if the gain would not justify the means!
Was I changing just to change.

Margbarn, I did initially check out the 5550 and 5570 and read numerous reviews about them.
I was really at a toss up between them, funny that you should mention that.

In the reviews the 5770 was getting a bit of a leg up over the 5570, more in the Gaming Dept. than Blu-ray/ HTPC.
Though I do not really do any gaming with my HTPC at this point, I figured that if I happened to pick up a game in the future, the 5770 would give me a slight boost over the 5570.

I went to Best Buy and there they were side by side, the 5570 & 5770, I also had a $50.00 gift card, so you know how rationalizing purchases in your head goes...at least I do! LOL!
I thought gee with the $50.00 card I could make a step up and get the 5770, no extra $$ out of my pocket...didn't take much convincing in my head, grabbed the 5770 and I have not looked back...well....until I saw the 460 reviews!

I wanted to make sure that if I went with the 460, that it was a really big step forward and not just a sideways move.

Thanks for the responses...I'll stick where I'm at!

I got both the 5770 and the 460 768MB. The 460 is considerably faster for games, but for HTPC they both have their bugs. Many more people are having levels problems with ATI drivers, and although this has gotten better with the 5000 series, it's been there for many generations (even before the 2000 series). On the other hand, ATI's HDMI audio is working a bit better right now, it's compatible with all blu-ray bitstreaming commercial players, and it doesn't have the silent stream bug anymore. Nvidia's supposedly on its way to fixing the former, but I don't have hopes they will fix the latter.

If you just wanna switch to Nvidia for HTPC, I'd recommend to just wait a bit till the new cards come out, especially the 450 and 430.

I just wanted to share my experience setting up my HTPC with a GTX 460 yesterday.

I got a Gigabyte GeForce GTX 460 OC 1G card, mostly due to its silent design.
It fits perfectly into the Antec Fusion Remote case, although routing the power cables was a bit of a hazzle, but what do you expect from a small case like this.

Anyhow, after assembling the whole system, i went to start it up, and everything appeared to work fine.
However, one bump i hit after i finished installing Win7 and installing the nvidia driver (latest WHQL from nvidia.com, at the time). I wasn't getting any picture, and my A/V Receiver seemed to cycle through HDMI modes, something funny was going on there.

I can't be sure what was wrong, if its the mini-HDMI on the card, or the mini-HDMI-to-HDMI Adapter they gave me, but using a DVI->HDMI Adapter and connecting through that worked fine, and the problem was solved. Even full Audio seems to work fine through that connection.

Anyhow, next was testing video and audio capability.
Playing a DVD in WMP actually bitstreamed the AC3 to the Receiver, i honestly didn't expect that to happen!
In MPC-HC with ffdshow and Reclock, bitstreaming seems to work just fine as well, although i didn't have a chance to test DTS-HD yet, but DD, DD+, DTS and THD seemed to work.

Video decoding with MPC-HC is working fine as well, VC-1 and MPEG-2 with DXVA, but i'm using CoreAVC for H264, so i didn't test the DXVA codec for that one, but i'm sure that will work as well.

I didn't bother testing real 24p mode yet, as it got late and i just wanted to watch some movie. Additonally, i never really noticed the 3:2 judder.. *shrug*

Anyhow, later this week, i'll do some play testing with the card, and hope it performs good in that area as well. =)

this was taken from the following HTPC guilde:avsforum.com/avs-vb/showthread.php?p=18816470#post18816470

Only under Windows 7, Dolby TrueHD/DTS-HD bitstreaming via ffdshow is supported. (HD audio bitstreaming via PowerDVD, TotalMedia Theatre, and WinDVD works fine under Vista too.)

MicroCenter has a 768MB version GTX 460 for $160 (after $10 MIR).

I wrote my own WPF screensaver over the last couple of days that mimics the behavior of the windows live saver, but it plays the whole video! If you want something done right, sometimes you have to do it yourself. WPF rocks. I'll be upgrading the HTPC to Win 7 in the near future.

You won't regret that decision.

Agreed. Win 7 is absolutely the right way to go. Especially for the HTPC world.

Hi guys.

I've found 460's DVI output sends HD bitstream as well.
I used a DVI to HDMI cable between 460 and AVR in and an HDMI to HDMI cable between AVR out-TV in. Used MPC-HC/ffdsow.

That's expected. HD 5xxx (with ATI's DVI-HDMI adapter) and Intel HD Graphics support HD audio bitstreaming over DVI too.

Thank you!! You just saved me from throwing money at an overpriced
mini HDMI cable. I had completely forgotten about the DVI output
being able to do audio as well
.

You can get a cheap ($5-8) mini-HDMI to HDMI adapter from amazon.com too.
But I prefer the Zotac and Palit GTX 460 cards for their full size HDMI ports myself.

Thx rene,

1) I have to admit i didn't know nVidia's DVI is able to send HD bitstream.
I was awared when i got stereo sound from my HDTV while i was trying to install two different monitors.
When i connect DVI out to my TV's HDMI in i got audio over Philips TV. Nvidia control panel had already selected "HDMI HDTV audio enabled" option by default on "Philips FTV monitor".

2) I have an HW issue with my 5770's HDMI output. DVI works by alone for only video. I've lost my DVI to HDMI Ati adaptor but without it i couldn't find any "Ati high definition audio device" under "playback devices"?

3) I haven't tried Intel DVI. Does it work with a DVI to HDMI cable like nVidia?

You're welcome. But i found it accidentally



That is what i prefer; i use two monitors:

Just video over DVI to HDMI > HDTV in directly:









Just audio over HDMI to HDMI > AVR in (no HDMI out from AVR):








_ _ _ _

So.......I here a lot of people saying wait and we have a few jumping to buy the gtx460 with the driver update to 258.96!
I currently have my HTPC waiting for a card. My old ATI card would not send sound to the Onkyo (608) receiver via HDMI (even with the Ati updates) Not doing any gaming.

If I wait for the new cards to come out what's to say that they don't have issues with bitstreaming?

Your thoughts please.... Go with the 460 or grab a cheap one for now to watch video w/o the HD audio and hope that 2 months from know we can make an informed decision.
