HTPC for 3D iso playback

post #1 of 15

Thread Starter 
hi,

I am in the progress of upgrading my HTPC to playback those 3D Bluray iso file. I have the following setup for my htpc

- CPU : AMD 4850e
- MB: 780G
- GPU: MSI HD 6450

I am wondering if these would be enough to playback 3D image files, they work fine for normal 1080P movies. I also have a Onkyo 607 for the AVR.

Anything else i need to be aware off?

thanks,

You said 3d bluray and then you said 3d image files. Are you trying to watch 3d bluray movies? Or just look at pics? I assume you have a 3d tv?

I believe the 6450 can do 3d. You need to get a commercial blu ray software like Arcsoft TMT or PowerDVD.

Also one thing to consider it looks like the onkyo is not HDMI 1.4. So you would need to run video straight from the video card to your TV. And then if you want to use the
receiver for audio run that separate. I have done this in the past with a dvi>hdmi adapter. But I had better luck with Nvidia than AMD.

thanks, i mean 3D bluray image file = iso.

I am not using a bluray player, but instead mounting the iso file to a virtual drive then run them with PowerDVD or TMT. Would this require more CPU power ? or it's all on the gpu? do I need to upgrade CPU as well in order for a smoother experience??

As for the HDMI 1.4, are you saying I need to run video via HDMI on the video card, the audio via DVI from the video card separately? why would I need to do that? is it only for 3D playback or for regular 1080p playback as well?

thanks,

Heres some info about your gpu playing back 3d. It is offloading to the gpu but the cpu is still at 25%. Thats a six core high end amd cpu. Yours is pretty low power. But the gpu should be handling
it so I would try it out first and see how it works for you. Unless money isn't an issue. A new cpu may require a new board not sure what yours accepts.

The HDMI 1.4 thing is only for 3d yes. 1080p will be just fine. But if your AVR is not HDMI 1.4 then 3d bluray ISO's won't work. Stuff like side by side 3d MKV's you can make with DVDfab will work. As they are just a 1080p signal.
But your AVR can't handle the stuff on bluray discs which I believe is dual 1080p streams.

I have the same issue with my AVR.

Just tried my setup, it runs ok with "Enforce Smooth Video Playback" disabled. With that setting turned on , it just lags like hell.

I am going to try connecting from my video card to TV via HDMI, and route the audio separately see how it would work. With this setup , do I need HDMI 1.4 ? or 1.3 is sufficient?

I never use 3D natively on my TV, usually I convert 2D to 3D that works ok when I play video from my HTPC via AVR. Is there any setting i need to do on my TV?

thanks

You need hdmi 1.4 for the video from gpu to tv. Which they both should be. The tv should detect a 3d signal. If not go into the tvs 3d settings and turn on auto detect. You of course also need the proper blu ray software on your pc.

thanks,

onkyo 607 does have a HDMI 1.3 repeater, does that mean it will pass the signal to whatever (TV) if it doesn't know how to process the signal?

No it will be downgraded to 1.3

If your receiver is only 1.3 you can not send the video through it for 3d blu ray. There is no work around or way to just pass the signal as far as I know. I had a pretty big thread going on this a while ago as I was in the same situation as you.

Have you tried hdmi straight to the tv to test a 3d blu ray yet? You said before you were just doing 2d>3d. Which is definitely inferior to a real 3d disc.I would get 3d working first and then try to test audio to your receiver.
FYI you can get audio over DVI. I think with AMD you need the proper dvi to hdmi adapter that supports audio.

alright, thanks that clears a lot of question I have. I am waiting for my 1.4 hdmi cable to arrive for the native 3D test. Meanwhile the 2D > 3D conversion done by the TV works pretty OK too.

I'll do a test alter to see if the dvi->hdmi adapter does audio. Worse case is that I have to route audio via the onboard optical which only support 6 channels.

The hdmi cable you have will probably work. There is no such thing as an hdmi 1.4 cable. It's marketing. I think it does require a high speed hdmi cable which many are.

just tried connecting from he gpu to tv directly with the high speed hdmi cable, it works great !!! native 3D look awesome!!
however i wasn't able to get audio to work over DVI-HDMI converter, so instead I route the audio using the optical out.

it's kinda suck but at least the 3D iso playback is working smile.gif

i guess i need another way to get the bitstream working ~

how about a HDMI splitter? would that work?

That's a good idea I don't see a reason why it wouldn't.

I'm curious whether anyone is doing this, because when I looked into splitters the ones I saw all said that the audio quality on both outputs must be the same. That is, that you couldn't send, for example TrueHD to one output and DD or analog audio to the other. Since the TV probably doesn't accept HD audio and thus the HDCP probably won't allow you to send HD audio to the TV even if you don't care if it can decode it, would you be able to send HD audio to the AVR? Or would you be limited to the best quality audio that the TV will accept?

If anyone knows of a switch that doesn't have this limitation, (or a way around it) I'd really like to know because I could really use it.
