[WINDOWS][PATCH]Bitstream output of HD audio formats

henrikyo · 2012-05-01 23:53

Btw, since i have to disable dxva2 on my mac mini, does it still handle high bitrate bluray rips okay, its the 2011 model with dual core sandy bridge 2.3ghz?

I'm using build 11.0_HD_2010417 and I've found that in XBMC the video slows down every few seconds. I've tried MPC-HC x86 1.6.1.4081 and the same video is smooth.

I don't have the same configuration in XBMC and MPC-HC (for example, MPC-HC has a default config, no codecs installed in the sytem so is using the ones built-in) but I'm thinking in a configuration problem or XBMC problem here.

My setup is the following:

PC with AMD Radeon HD 6450 (Windows 7 x64):

- DVI to a 20" LCD @ 1680x1050
- HDMI to a 42" TV (Philips 42PFL8404H @ 1920x1080) through a receiver (Yahama SR-301)

I'm using Catalyst 12.3 with the HDMI Audio Driver. I've setup XBMC as in the pictures in the first post: HDMI, 7.1, AC3, DTS-HD Master Audio, DD+, DolbyTrueHD and WASAPI on AMD HDMI.

Do I need to configure XBMC, Windows, Catalyst, etc. for smooth playback? I'm thinking that the Yamaha nor the TV affects the playback because using MPC-HC plays smooth but please advice about these devices would be very appreciated.

Thank you.

PS: I'm pasting the info of one of the files that play slow every few seconds to see if it helps:

Code:

Is this slow movement the "famous" judder effect?

U sure thats the right file, since the ac3 audio track etc

Try these-

1. Select AMD HDMI audio output in Windows 7 control panel
2. Select AMD HDMI audio output and select WASAPI: SR8002 (high definition......) in XBMC settings/system/audio output
3. Disable "DXVA2" and everything else in XBMC settings/video/playback
4. Disable "Use a fullscreen window rather than true fullscree" in XBMC settings/system/video output

tried the above and still the same issue Sad

could it be its not compatible with my 7750 GPU?

Any of the Sandy Bridges, i3 and up, are very capable of software decoding even the most demanding bluray remuxes. Even the older Clarkdale i3's have no problem software decoding high bitrate remuxes.

@a5ian300zx - post a log pls

I know that you said the driver is up to date. Did you update Intel driver and AMD driver from the links below?

Intel- Check your system for the latest updates. You might need to install this "Intel Management Engine Interface Driver" too......

AMD- AMD Driver Autodetect

-You have a very powerful AMD GPU. It should work with DXVA2 enabled with DXVA as Render Method.....if you want to verify your AMD GPU, you can always try the standalone TMT5, PDVD11 or MPC-HC.....

-You have a very powerful Intel i5-2500k too, and it is equipped with a handsome HD3000 iGPU. If you cannot get it to work properly with AMD HD7750, you might want to try i5-2500k/HD3000 instead. It should be able to playback blu-ray in full 1080P and bitstreaming HD audio with ease....

hi,

DDDMain: which log file?

bluray: I have the intel 2500T with HD2000 GPU would that be sufficient enough?

I have internal audio and GPU disabled on system via BIOS motherboard.

one weird thing i did pick up was that under sound options in WIndows 7 there are like 6 option for digital audio.

@ a5ian300zx: i have an intel i3-2120T with HD2000 and this is enough power. i use wasapi for dts hd ma with full success.
and he means the log file in ..\AppData\Roaming\XBMC\xbmc.log with enabled debug-logging in xbmc
cheers

**DDDamian** · 2012-05-02 16:05

@Nimo - thx. A good way to do a debug log is via the addon built just for it here.

Telling us what those six or so digital options are would be helpful too.

I have a weaker Intel i5 with HD2000 and it can playback fine.....just disable DXVA2 in video playback and select WASAP in audio output, it should be good to go....

Thanks guys will get the debug up tonight, the six inputs i have no idea they was only one with my last 6670 card.

here my card
