Hi,
I think it's the trace tabs in DvxaChecker ? ...

so for Mpeg2 test , is it suffisant to confirm that dxva is used ?? :


For your information my system is a T91MT under Windows 7 (Atom Z520 1,33 Mhz with GMA500 graphic card) overclocked with SetFSB up to 1.64
I have tested up to 20 Mpeg2 files ... and all seems OK ... At basic CPU frequency, overclocked and underclocked (in Tablet mode state : multiplier go down from 10 to 6)
I have also tested (few) mp4 HD ... and all run fine (with unchecked conv. option) but only at CPU overcloked frequency ... no test at basic (I have to do )

Even if we need more test ... GPU accelaration in VLC must work on Intel GMA500 BUT with only lastest driver (2026) .

Philippe.

Indeed, it is it

So this is with RC4 ?

Hi,

NO it's with the "official" one ... from your main site ... I used RC4 only to check if some diff. exist between RC4 and the "official" ... but now ALL run and test, are done only with the Official (and the last Intel Driver ... )

Philippe.
Thanks and Thanks again for the great job ... for small "tablet like" netbook it's so funny, another benefits is that dxva usage reduce the power comsumption of the T91MT, so I can see more than 5 Hours of dvd (on battery) without any problem.

Indeed, that is expected

I just tested it and it works like a charm!

CPU: AMD Phenom X4 9850 BE
GPU: GeForce 9800 GTX +
OS: Windows 7 Home Premium (64 Bit)

Looks like Catalyst 10.7 is coming this Wednesday. Is there any ETA on VLC 1.1.1?

Soonish =)

Can't wait to try it.

very soon.

Is there any chance for core i based intel GMA HD graphics to work with VLC player? I've tried it with the latest drivers with video acceleration enabled (core i3 baded dell laptop)) but I only see geen screen.

No, until we have some hardware to test, this won't happen.

Hi,
For your information :
some new test with GMA500 Hardware accel. on my T91MT (Z520 Atom proc. at 1.33) GMA500 1024x600 Windows7 (Home Prenium X86) VLC 1.1.0

I have done some other test with a cynergy dvb-t usb dongle ... with the terratec program it's impossible to see anything ...
with vlc AND hardware acceleration ON (I do a verification with trace of DVXAChecker)

I am able to have an excellent result with SD channel ... Mpeg2 Hadware accel. is called and video is good without error after hours.
With HD channel the result is less ... I have lot of artefact (green square) BUT ONLY on the top of the video (~ 50 pixels height) sound is good ... the problem seems comming from the video size that don't fit with the resolution supported by gma500 accel.

I have to do more test ... sorry, but it's not easy to manage command line for dvb-t and I am not sure to do the good choice.

BUT AT ALL the hardware acceleration work also fine for Mpeg2 DVB-T source, like previous test with DVD.

I will try to run more tests to understand why Mpeg4 H264 file play well and not DVB-T H264 flow ....

Did you have some other test return with GMA500 to don't replay and fall in problem already solved ?

Thanks again for job.
Philippe.

I just recently downloaded this and ran the tests. My platform is as follows:

Windows 7 64 bit
Mother board ASUS P5QPro
CPU = E8400 dual core @ 3.0 Ghz
8GB dual channel RAM
Nvidia 9800 GT
Nvidia driver 257.21
Playback to Samsung 750A LCD monitor (52")

I watched all of shutter island with and without GPU acceleration. H.264 with DTS (3.2/LFE)
Parts of other 720P/H.264 material with and without GPU acceleration. H.264 with DTS (3.2/LFE)

Without GPU acceleration the CPU averaged 20% +/- 1 with the occasional peak up to 28%.
With GPU acceleration The CPU averaged 6% +/-1 with the occasional peak up to 11%.

I watched all of Shutter Island and my son watched with me the second time (I wasn't paying complete attention but told him to notify me of anything odd). I found absolutely no difference in vidoe or audio quality. It's nice to get that extra 10-15% of CPU usage back. From the tests I did this works flawlessly. If there is a ny especially problematic material you would like me to try let me know.

I am about to get ready some 1080P test material and see what I get.

some other files with same codec but 1280x720 resoulution play also fine

Playing videos with the GPU decoding feature enabled freezes my computer. Using CC 10.7.

Win 7 64 bit
AMD Phenom II 940
ATI HD 4890

Edit: It seems to work now that I've rebooted. CPU usage for 1080p video = maximum 1%, before: 7-8%. Great feature!

Rebooting after drivers update is expected, sorry...

Cool stats

I'm having an issue too with VLC 1.1.1 and Catalyst 10.7. I made a post in the general troubleshooting forum because I'm new to the forum and wasn't sure where it went. Anyway, with GPU acceleration enabled, videos are very choppy/stuttery/pixelated whatever you wanna call it - it's unwatchable. I even downloaded the latest June 2010 DX redist and still the same results. It was even the same with Catalyst 10.6. The 10.7 drivers don't seem to change anything at all for me.

Specs:
Windows Vista 32-Bit
ATI Radeon HD 3870 (Catalyst 10.7)
Quad Core Q9300 2.5ghz
4GB Ram
VLC 1.1.1

Edit: I have rebooted since installing 10.7 drivers and still the same result.

I have it enabled and on that Iron Man 2 video I have 25% usage

ATI card working as perfect as possible with 1080p videos now.

However, when I tried a 2160p, I got a BSOD. I don't know if it was caused by VLC or Catalyst.
With GPU acc. disabled, VLC can "play" it fine. I mean, it shows one or two still frames, then the film ends, but the computer doesn't seem "fully overloaded", nothing crashes.

I'm looking for info about it on ATI forums/support, but I'd appreciate if someone else try to reproduce it and tell the results.

Edit: and AMD/ATI moderator confirmed that 2160p acceleration is not supported.

From Catalyst 10.7 release notes (http://www2.ati.com/relnotes/catalyst_1 ... _notes.pdf), GPU acceleration fix for VLC is only for HD4000/5000 families.


I tried to do some performance testing on my HD5870 :
input : TS 1440x1080i50 8Mbps (French DVB-T)
output : (I cannot use NV12 here, it crashes) --sout=#transcode{vcodec=YV12}:standard{mux=avi,access=file,dst=NUL}
I get about 140fps (CPU usage between 2% and 4%, Core i7 920 @ 3.8GHz), which seems to be about the same as software decoding (with one maxed core, so 12.5% CPU).

BSOD shouldn't happen, and I fear the issue is in the drivers... But if you could share logs or messages from before the crash, that would be cool.

Dxva2 works fine with my integrated HD3200, but maybe 3xxx series "cards" not supported. The same happened with flash 10.1 gpu acceleration.
Win7 64bit, Phenom II CPU, 780G chipset.

HD3200 is a bit a special GPU...

Yes, as I said when I edited my post, it is Catalyst's fault. See this thread: http://forums.amd.com/game/messageview. ... erthread=y
If you still want the logs, can you tell me where they are stored?

Hi! DxVA2 works fine on my computer with Vista x64 and ati HD4830.
The only problem I noticed is that the subtitle rendering in white, works, in any other color show differet tonalities of blue
