Core i7, i5 & i3 LGA1156 Processors Thread: Clarkdale Supports HD Audio Bitstreaming! - Page 75

I actually use use WMC pretty much exclusively for WAF. I use MPC as a debug platform, or a player of last resort when my kids really want to watch something and my experiments have made WMC no-workee. Like now.

MPC plays the file with what appears to be its internal MPEG2 decoder, but including the Gabest MPEG2 decoder in Graphstudio doesn't work-- in fact, no codec in Graphstudio appears to be able to play the file.

I'm stumped.

Try installing the standalone MPC-HC filters, the internal filters won't show up in GraphStudio.

It could also be a merit issue.

You need to use a WASAPI renderer to bypass the mixer.

SOrry I've been focusing all my time on bitstreaming BluRay lately and haven't researched the music side. Will a WASAPI play thru the Media Center interface (WMP). Did a quick google on WASAPI renderer and don't see anything about it with WMC

Thanks

You can use Reclock and the MPC-HC audio renderers with WMC, but Reclock breaks live TV and the last time I used the MPC-HC renderer it was pretty beta.

Many Thanks!

Jeff

I should add that it's been a few months since I looked at the MPC-HC renderer. It could be much better now.

It's a shame that MC doesn't ship with an optional WASAPI renderer.

I believe the o/s and driver can reallocate this memory as it feels like it. To my knowledge, the bios setting is only the initial allocated memory until something smarter (driver) takes over.

So any other suggestions on how to get no Green Band/Flash issues when playing back AVC/MPG4 media? I have tried the Microsoft DVD-DTV on MPC-HC. Are there other codecs I would need to install to get this issue to go away? I want to make the playback seamless for my Wife to use without having to tinker anything.

I was only seeing the bands in MPC-HC when using internal decoders. Once I configured it to use Microsoft DTV-DVD decoder and unchecked h.264 I no longer had the problem. Tested my whole library last night and they all played good. Although I don't have any of the same movies.

Still trying to get some HWA for VC1 in MPC-HC and DTS HD Master Audio to bitstream without downsampling.

Doubt it makes a difference, but when intel released the 2086 driver under "HD graphics" section, not just the intel boards, I installed it.

Make sure you disable AVC/H264 in the internal decoder as well.

Do you mean to uncheck these boxes in MPC-HC? Do I do this when using the MS DTV-DVD or using the FFDShow decoder?

I'm just talking about the BIOS reserve portion. Windows will show xxx usable and that's the portion it can play around with. My concern is that the usable portion is less than what it should be with a simple subtraction of the 128mb from IGP.

After adding the MS decoder as an external filter you want to disable AVC/H264 for the MPC-HC and FFDShow decoders.

Yes, click internal filters, then under transcoder filters uncheck the h.264 filters. Leaving checked means MPC will use it's own filters, unchecked means it will use whatever the system default is. If you have ffdshow configured to decode h.264 then that will probably happen so if ffdshow is decoding (you see ffdshow video icon on systray when playing) then you might need to set ffdshow to not decode h.264 as well.

My point is windows is probably choosing to grab more memory for the IGP than you've allocated via the bios due to running aero, etc. Again, AFAIK the bios setting only applies until a driver takes over.

I think what you allocate from the BIOS is supposed to be allocated as "dedicated" but windows will take as it sees fit for "shared". The dedicated part doesn't change and drivers can plan on it being there, but shared grows and shrinks so there are some considerations that needs to be made for devices to use the shared memory. Maybe I'm completely wrong just my understanding.

this thread begs for a "current known issues" thread of it's own similar to what somebody did for the ATI solutions as navigating this thread for tips is becoming onerous.

Can anyone say they are perfectly happy and have video and audio bitstreaming for:

-MPC-HC
-TMT
-WMC
-PDVD

for 24Hz or 60Hz on

Win7 or XP?

I'm as happy as a pig in ****!

I use 7MC+ media browser + MPC-HC and I can play avi, mkv and BDMV with full bitstreaming at 60Hz. I just finished watching Terminator Salvation and everything was perfect.

I use 7MC+MB+MPC-HC and can play all my DVD/BD/HD-DVD rips using FFDShow as my preferred audio output and using MS DTV-DVD video output decoder. I am able to bitstream without any issues.

That's exactly what i think. So the dedicated portion should not change. It is the baseline minimum allotted to the gpu by the bios. So what are y'all getting? I set a side 128mb but Windows reports BIOS set aside 330mb, so what's remaining is 3.68gb usable in windows.

Pretty happy with using it in MPC-HC. Would like to get VC1 HWA if it's even possible and DTS HD MA bitstreaming without it downsampling. But I'm not sure if those are even possible.

WMC not so happy but still need to put more time into it. Had problems with live/recorded TV being REALLY choppy. Suspect the tuner and have a new one coming on Monday to confirm. Other issues are Win7 related not i3.

Here's my status with the Intel Clarkdale I3-530 w/ Biostar H55 MB, Win x64, 60hz TV, Pioneer Elite receiver, .2086 drivers:

MPC-HC w/ FFDSHOW audio, I can bitstream the following with no issues:
DD/AC3
TrueHD
DTS
DTS HD MA
DTS HD HR

LPCM is output as 6 CH (I have 5.1 speakers) but could go to 8CH.

On the video side, my preferred video decoder for VC-1 & H264/AVC on my previous Nvidia HTPC was the Gabest MPC decoders but for Intel, they don't work quite as well yet. The H264/AVC decoder has blocking and green bar issues while the VC-1 decoder won't even play.

I've used FFDSHOW software video for both codecs with great results. It plays all formats flawlessly but it's not DXVA.
I'm currently using the Microsoft decoder that came with Windows 7 for H264/AVC. I think it's called MS DVD-DTV.

On the VC-1 side, I tried the custom intel SDK decoder but have had bad results. Seeking locks up the video and overall sync issues.

So I'm still using FFDSHOW software (DXVA isn't supported yet) for VC-1.

I'm running this all through XBMC launching MPC as an external player and quite happy now. The nice thing about it is that it has enough muscle to play the video in software with only 15-25% CPU while I wait for the DXVA issues to be resolved with MPC and FFDSHOW.

TMT3 does video hardware acceleration good but it won't bitstream any of the HD audio codecs for me.

From what I understand, when you are bitstreaming DTS HD MA and the receiver lites up "DTS HD MA", it's not being down sampled. Are you using FFDSHOW to do this?

Wow I've spent three days messing with my system, and reading endless hours of forum posts looking for a solution, and I'm at the point of giving up or quitting my day job to focus full time on being able to listen to a blu-ray.

I have:
i5 661 on a \
Intel DH55TC Motherboard
using TMT3 (170) in Win7 x64
hooked up to Onkyo TX-SR606
Tried Intel Graphics Media Accelerator drivers (1995, 2021, 2082, 2086)

I have got all audio working except DTS-HD MA and Dolby TrueHD from Blu-Rays (discs or images). Is it possible to get it working at all? I've seen so many posts of people with Clarkdale's and intel mobos claiming to have bitstreaming working, but I think some of it may be outside TMT3 (not from blu-ray). Am I wasting my time?

I also heard some rumblings that the EDID of some Onkyo receivers was buggy and misreporting the receiver's supported formats. I'm not sure that's the case with mine, since last week I was bitstreaming audio from TMT3 using the Asus Xonar 1.3, it's only after "upgrading" to the i5 that I can't get it to work. I've also tried replacing the plug and play monitor drivers with a hacked EDID .inf file that I found that was supposed to be for the TX-RS606, but that caused endless problems (no display, had to system restore).

Sorry for the long post, I'm basically just wondering if I should wait a month or two for a new version of TMT3 and/or new drivers from Intel before wasting more of my life.

I'm able to bitstream DTS-HDMA and Dolby TrueHD with my Core i5 661, DH55TC, Win7 64-bit, graphics dirvers 2082, TMT3 170. The only obvious difference between my setup and yours is that I have a different receiver, a Pioneer SC-05 instead of an Onkyo 606.

Hey gorthocar, when you goto Control Panel -> Sound -> and check the properties of your Intel Display Audio device, does your "supported formats" look like this?

Supported Formats
TX-SR606

The following audio formats are currently supported:
Max Number of Channels: 2
HDCP: Supported
Bit Depths: 16-bit
Sample Rates:
48.0 kHz
Encoded Formats:
No compressed formats found.

I've found rumblings that it should list alot more, including DTS-HD MA under here and TrueHD under here, but mine is pretty empty. I'm guessing that if it's supposed to list all of the audio formats my receiver supports here, then I actually do have an EDID problem, and have just no way how to fix it.

That seems like what the TV is able to handle. Maybe the receiver is simply passing through the capabilities of the TV to the HTPC instead of its own capabilities.

does anyone know how to set the chip to output 24p? Is that just a matter of changing the refresh to 24Hz?
