my pc spec
amd barton 1.8ghz
geforce 7600gs (pixel shader 3.0)

i do the following to maximize performance when playback 720p, which is quite smooth with my spec of pc

-mpc-hc as media player
-use haali renderer (best performance among the other renderers VMR9 and EVR, although on some videos it will display wrong framesize, such as youtube .flv)
-use haali media splitter (compare to internal mpc splitter, it is noticeably faster during seeking)
-coreavc (faster than divx7, ffdshow, or internal mpc decoder)
-audio decoder no difference whether use ffdshow or internal mpc decoder

1080p videos cannot playback smoothly, though.

1080p playback requirement is very high, dual core 3.0GHz is a must to ensure smooth playback with software decoder, and decoder must be ffdshow multithreaded version, Dixv7.
mid-end GPU is a plus(video frame buffering).
if the software decoder is Coreavc, CPU requirement might lower abit sinec its pertty fast.
Downside is, high CPU usage.

if user's GPU is ati HD2000 series / Nvidia G84 series / Via S3 Chrome 430GT / Intel GMA4500MHD GS45 and better, minimum CPU spec = 1GHz, with mpc internal h264 Dxva decoder(VIA S3 Chrome and Intel GS45 status is unknown).
Advantage = low CPU usage,
Downside, if the h264 video was encoded without using Dxva-compliant settings(refrence frame more than 7), Dxva decoder will failed to work, and software decoding mode will be painfully slow.

anyone has AC3Filter 1.46 x64 experiment build?

^ wrong thread
btw, no even i googled abit, there is no x64 version.
you have 3 choice,
1. grab a msvc9 and compile a x64 version of ac3filter youself.
2. ffdshow x64 version
http://sourceforge.net/project/showfiles.p...lease_id=569930
3. mpc-hc x64 version
http://www.xvidvideo.ru/content/category/1/1/2/

before anyone ask, the 3 app listed above are using the same thing, liba52, for ac3 decoding.

this is only make it smooth right?
not improve the quality?
the quality is depend on the movie,media player change the quality right ?

Improve quality?
every media player will output the same image quality, unless user is messing with the image filter (postprocessing, denoiser, equalizer, of course doing it wrong will degrade the video quality, though those filter are not possible to enable on realtime)
or the decoder is bugged.
Yup the quality is depend on te video itself,
the Dxva decoder will still output the crappy image if the video was pooly encoded.

Good stuff for my H264 files..

usefull info here!!

i have the same to, only using MPC.

Is this ok?...i need ur opinion guys

I already use this method long time ago.
Im using Celeron Dual Core With Asus HD4350 GC.

I already tested a few trailer & anime 1080p and its Work fine...

Using : MPC+HC Bundle With K-Lite

Just i dont have any movie with 1080P. anyone want to share to me for test pls PM me. I can pay for postage :-D

Apple HD h264 video from here http://www.apple.com/quicktime/guide/hd/
for example BBC Motion gallery, Japan:
720p http://images.apple.com/movies/us/hd_galle...-japan_720p.mov

1080p http://images.apple.com/movies/us/hd_galle...japan_1080p.mov

Please note that apple HD gallery only using Main Profile, not the most CPU demanding, but its enough make your CPU choking if Dxva doesn work or disabled, and system requirement not meet.

for those who want to run HD 1080p movie with low rig
here the trick
HERE

not support for GC 7xxx , 8800 (old version) and below

summary:video rendering go to GC.not CPU any more.

ps:i cant load the sub tat "build-in" the .mkv

Good info thanks..media player 10 works for me for HD clips with K-Lite Codec pack..pentium 4 HT here lol

nice tutorial. is it pinned? very clear...

how should i do..? my gc is 7900gs and play with Final_Fantasy_Advent_Children_Complete_(2009)_[1080p,BluRay,x264,DTS]_-_THORA.mkv

it keep lag..sound is smooth, but sometime the movie is lag..how to fix it?

^ 7900gs is old gen GPU, it does support h264 Dxva, but only iDCT or motion compensation,
http://en.wikipedia.org/wiki/Nvidia_PureVi...on_PureVideo_HD

While mpc-hc dxva only support bitstream decoding,
its completely offloading the decoding to gpu,
but only supported on new gen nvidia GPU G84 and newer.

try Dixv7 h264 decoder, if its still lag, times to upgrade your hardware

divx7 cant.but i use download coreAVC Pro..seem it solve my problem..

Yeah, CoreAVC pro is the fastest software decoder, which support CUDA but only for nvidia.

Here is the timecodec bench for various free h264 decoder with h264 video, 1 minutes 47sec, high profile, resolution 800x592, Null Renderer is used.

Does HD2400 supports DXVA / encoding video using GPU instead of CPU?

If you are not sure what is your GPU an would like to know whether if its support Dxva. try Dxva checker.

screenshots: http://bluesky23.hp.infoseek.co.jp/dxvac/ss.html

if you dont see ModeH264_VLD_NoFGT of first tab, your graphic card does not work witj mpc-hc h264 Dxva decoder, only software mode.

Encoding video using GPU only work if your GPU is HD4000 series.
