Greetings from Germany,

think i have something for you i´m using an Acer 751 (11,6", 1366x768) which has the same hardware as your Dell. Currently i´m able to playback all HD Videos with my acer: Super smooth, and only about 20% CPU usage.

H.264 /AVC - 1080p

I strongly recommend you to try this littel tool:
http://bluesky23.hp.infoseek.co.jp/d...er_2.0.1.2.zip

It shows you the Hardware capebilties of your GPU, and below that a list of installed Codecs which can be used for DXVA playback. Take a look at my screenshots.

Further you should click "Check DirectShow Decoders..." and search for a video file you like to view. In the screenshot i used this: DivX 7 Showcase | DivX.com rather heavy stuff (1080p H.264, AAC 5.1 Surround, AAC Stereo, 507MB)

With the free codec that comes from "Media Player Classic - HC" there is no problem playing your H.264 Videos. Here is a good guide how to trigger DXVA: Hardware acceleration of HD movies using DXVA - Guides & Tutorials

Playing your VC-1 coded videos like WMV is a bit tricky, but will work. You need a VC-1 decoder which comes directly from intel, but is somehow hidden from their site. Here is a upload: File-Upload.net - Intel_Video_Codecs_GMA500.zip

If you install it and run that DXVA-Checker Tool, you will see there is another Codec like in my screenshots. "Intel® Media Codecs VC-1 Decoder for Intel® System Controller Hub"

Download some Samples here: WMV HD Content Showcase

Within the DXVA-Checker Tool look for the button "Check Media Foundation Decoders..." click and choose a WMV file. Rightclick on the red text below the intel codec (NV12 (ModeVC1_VLD)) which should look like my screenshots and choose play, enjoy!

With the use of the MPC-Codec and the Intel one for VC-1 you can play every HD-Content with minimal CPU usage on your GMA500. Just make sure you run on DXVA (Hardware GPU acceleration)

PROBLEM: i cannot trigger this Intel VC-1 Codec in any Media Player. Maybe someone has an idea.


Greetings,

That looks awesome! Your screenshots of low CPU use tell it all. How did you find the VC-1 decoder and do you think there is one for the GMA950?
Thank you.
(and welcome, by the way)

Thanks for all this precious information...will take a while to digest ! I'll be back once I've gone through your remarks. A minor point, in Paris I believe that the asus and the acer are the hottest sellers : DELL watch out !

Cheers, Saxo.

@zrtom: thanks, i´d only like to share the experience i got. The VC-1 decoder was found in this thread: http://forum.pocketables.net/showthread.php?t=2531

@saxo (Citroen?): please tell me if my solution works on your Dell. Because all new Intel-Netbooks come with the GMA500, there will be a lot of customers wanting to try HD-Playback. No matter if its Dell, Acer, Asus... since we all use the same hardware/drivers we should work together.

IT WORKS

On Win XP with all programs closed:

Just realized the mkv I was trying to play was 1080. 720p plays perfectly with Media Player Home Cinema & K-Lite Codec pack. Core AVC Pro works great as well. I updated to the newest driver available from the Asus site but I don't know if that helped bc, as I said, I was trying on a (mislabeled) 1080 mkv before.

[Saxo]

Again, thanks FelixPaul, zrtom and Athena. So far, I have got improvement using MPC-HC and CoreAVC but I'm not sure I got the 'hardware acceleration' right. For the first time I can read a file from the wmv content showcase - that's great ! I haven't tried the WMP set-up yet (note that I have XP).

I also installed the driver from the Asus site - I think there is overall improvement there too.

Cheers, Saxo (as in W. Sacks).

PS : I couldn't get the VC1 decoder to work. Either because of XP or something I'm doing wrong.

[FelixPaul]

sounds good, but i have to tell you the CoreACV is only a software Decoder. It´s the fastest and will work for 720p on the slow Atom CPU.

But you would like to use the hardware of your GMA500. I´ve heard lots of peopole having issues (crashes) when trying to use the (free) MPC-HC codec for your HD-Videos.

At least you can always buy PowerDVD ;(

Actually we discuss this problem here:

FelixPaul,

Thanks for the post, this works really well. Is there any way to make the playback full screen? I know that utility is just for testing purposes.

Also I am trying to see if there a way to make this the default filter for playback.

Talked to our contact person at Dell today and he confirmed that they are aware of the crappy drivers for GMA500 and that a new release is to be expected soon. Nothing really new from that statement though.

New release already avail for Vista/Win7, Intel may or may not update the GMA500 XP driver though since it now an obsolete OS!
