High CPU usage in HD channels

Re: High CPU usage in HD channels

the best codec that work for me witha GT220 is the H264 Arcsoft codec (from total media theatre 5) and ffdshow audio decoder with dvbviewer pro.
You have to put the ASH264Vid.dll in the common> arcsoft> mpeg engine folder

Re: High CPU usage in HD channels

Hi.
Using CoreAVC doesnt do much difference comparing with PowerDVD or fddshow or LAV codecs or ..

But i noticed the coreavc icon is blue, so i dont have hardware accelaration..but why? i´ve read a lot that ATI 3870 is DXVA compatible and it does reduce cpu consumption..


Does VLC work with Plugins? I dont have access to a FTA HD channel.

If you are sure your card support DXVA acceleration , but you get blue icon (no acc) you have to check if
- you enabled DXVA in CoreAVC control panel (there are 3 options - soft, CUVID and DXVA)
- you have a latest DirectX 9 (june 2010), DirectX 11 from Win7 won't help

VLC is a player with integrated libraries of CoreAVC so it won't help you if you are unable to resurrect DXVA in CoreAVC.
And it doesn't work with CS plugins

And about other codecs
FFDShow is too slow
LAV codecs doesn't work correctly on every system.
For example it doesn't work in hardware mode with my TV system (NVidia ION, WinXP)

Thanks for the answer..

But it didint do any change on any codec. I´m really decided do purchase a NVIDIA card, at least i know that CUDA works quite well.

Cuda is for GPU computing, not proper for GPU video decoding, I don't know if anyone has write a video codec using CUDA function....

This is a codec using CUDA



And this codec too

Re: High CPU usage in HD channels

I use HDPack V.2.4 (freeware).
Arcsoft is the smoothest codec to watch HD TV channels with a 15% CPU power comsuption. And ffdshow as audio decoder. Video renderer 7.
As well I use Windows XP to watch Sat Pc HD video channels, because windows 7 freezes and for me Win XP is the best for my SkyStar HD 2 Pci Sat receiver.
And if you want to watch your recorded HD TV programs, you can download Splash pro lite (freeware version). Is a video player for HD videos, smoothly and low CPU consuption.
For PC Sat use Windows XP.
My Pc is a pentium dual core with 1,8 Ghz. 2 GB Ram memory DDR2, and Graphics card is an ATI AMD HD 4000 series. And works fine with HD channels.
Best regards.

Re: High CPU usage in HD channels

CoreAVC exists also for ATI/AMD cards?

These screenshots are from 2.0 version CoreAVC only supporting CUDA
Modern version of CoreAVC is 3.0.1 _http://corecodec.com/products/coreavc
This version supports DXVA acceleration specially for ATI cards.
When DXVA hardware acceleration is active, the tray icon is RED (green - CUDA, blue - software)
This codec costs 13$.
But there's easy enough to find the "remedy from the greed" over internet

Re: High CPU usage in HD channels

I strongly advise against coreavc as decoder, i did my tests it's not good
best: arcsoft h264 decoder( great for both dvb and blu ray) or power dvd also LAV codec
