I've been testing with a US15W platform with Atom Z530 CPU.
I've generated and tested a few versions of IEGD driver (including 10.1) and have failed to see any benefits on hardware accelerated playback.
I hope I am missing something obvious but here it goes.
I'm testing on either XP Pro or XPE.
A few questions:
1) I see no mention of SP3 for the XP family. Am I to assume using SP3 or XPE (Windows Embedded Standard) are not supported and should not be used?
I see a lot of mention of h264 MP4 hardware decoding, implying that the IEGD driver (as opposed to say the GMA500 driver) can tap into the hardware decoding features of the chipset.
But I have now compared playback of such media and less than HD media repeated times between the GMA and the IEGD driver set and seen no improvement with IEGD.
For this e-mail, my test media is encoded as h264/MPEG-4, at 1920x1036 resolution, with about 9772 kpbs.
2) While I dont expect the CPU to handle this, should I see ANY improvements in playback using IEGD with everything optimized?
3) Are codecs installed relevant? What codecs should I use to fully take advantage of IEGD?
I have a Combined Community Codec Pack and COREAVC.
I use Media Player Classic.
4) Does the media player matter? I also use VLC with no benefit.
5) Can someone briefly outline a test method (including comments on codec, player and media) I can use to show that the IEGD driver is in fact adding any benefit to my platform?
Welcome to the Intel® Embedded Design Center community.
Since you are using Intel Atom, I want to make you aware of a special place to go with your technical questions. The http://edc.intel.com/Community/ http://edc.intel.com/Community/" target="_blank">Intel e-Help desk is staffed by Intel representatives dedicated to answering embedded Intel® architecture product, design and development questions for select Intel processors, including Atom.
The Intel e-Help desk is only available to registered private users. Before you can access e-Help, you will first have to upgrade your community membership to private status. Private account status also allows you to access special documents and tools at the http://edc.intel.com/ http://edc.intel.com/" target="_blank">Intel® Embedded Design Center.

In the meantime, let's see if someone in the community can help answer your questions.
The codec used IS critical. If the codecs you have utilize DXVA (and I suspect they do NOT) then acceleration should be mostly automatic.
The codecs that we know are accelerated on US15w are available from Cyberlink with PowerDVD (these are as fully DXVA accelerated as possible) but to get PowerDVD to use acceleration properly you need to ask for the OEM version optimized for US15w and Atom. Hopefully they will be able to help you with getting that version.
