Looking for testers on Windows Vista/7 for DxVA2

[Jean-Baptiste Kempf]

Hello guys (and girls),

We are looking for people to test GPU acceleration under Windows Vista/7 for H.264 HD streams.

• Read the requirements here: VLC_DxVA2,
• Use DxVAChecker to check if you can do H264 decoding (look at H264_VLD),

Once you are there, use

• http://people.videolan.org/~jb/VLC/vlc- ... -win32.exe
• Install it
• Activate GPU decoding in preferences->input/codecs

Please report your tests, failures and successes.

You HAVE to tell

• your CPU, (and tell if you have SSE4, SSE3 or else, if you can)
• your GPU
• your OS
• the codecs in the file you tested

[VLC_help]

In case you are missing files suitable for testing, you can use for example http://showcase7.divx.com/Iron_Man_2_%5 ... _HD%5D.mkv (81.4 MB) that one.

seeing mixed results here

CPU: Core2Duo P8600 (SSE 1,2,3S,4.1)
GPU: ATI Mobility Radeon 4570
OS: Windows 7 Professional 64bit



other files with H264 MPEG-4 AVC (part10) (avc1)
resolution 1280x528 play fine

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

cpu uasge for all of them is about 30%

[Jean-Baptiste Kempf]

This is a bit high as CPU is concerned.
Can you try without OSD ? or see the consumption after 30 seconds of movie?
Do you see the DxVA be used (last tab of DxVAChecker)?

[nomiSimon]

with no acceleration cpu usage is about 50 to 30.
without osd its now between 20 and 30 still.
the log of DxVA tells me "DXVA2_DecodeDeviceCreated, vlc, 00:00:36.5796619"

edit:
and btw sometimes the mousepointer gets lost in the menus (right-click and under preferences)

[Jean-Baptiste Kempf]

Great, do you have CPU graphs screenshots ? Taskman->Performance view?

Thanks a lot for your testings. Can you try some 1080p ?

[nomiSimon]

i tested the iron man 2 trailer from above its very very stuttering/laggy with cpu usage in the high 50.
give me some minutes to get some 1080p files and make a graph of these, or you want also for the others?
you are very welcome

[Jean-Baptiste Kempf]

Well, CPU at 50 is usually one core peaking so, something is wrong...
Can you paste your messages (messages dialog, verbosity to 2) on a pastebin while playing (start it before play ) ?

[nomiSimon]

ok it seemed there were some problems on my side. sorry for that!
i cleaned the caches and preferences and now everything is really smooth again

pastebin for the given iron man trailer http://www.pastebin.org/74318

and a screenshot of a 1080p movie with codecs and cpu graph it stays in the 50 area

[Jean-Baptiste Kempf]

OK, seeing the log, you don't have GPU acceleration enabled

[nomiSimon]

ups sorry
now again for real!
http://pastebin.org/74338

[Jean-Baptiste Kempf]

Thanks again, a lot. Can you show picture of this resource monitor ?

[nomiSimon]

so here is the ressource graph with the iron man file


but it seems that there is still some problem with my other 1080p file. the green strip on the top and stuttering. could it be that jdwonloader is making some problems. because before after a restart it worked fine.
i will do some more testing when the download is finished

It appears that only the newer Quadro NVS models (285/440) support Pure Video but I thought I'd give it a shot anyways. Playback of the Iron Man file was extremely choppy and laggy with GPU decoding turned on with VLC Processor usage hovering around 2-4%. With GPU decoding turned off the file played perfectly, with VLC Processor usage being anywhere between 25-40%.

EDIT: Based on that, it seems it was sending it to my GPU correctly, but that the GPU can't decode it properly.

Output of DXVA Checker during that showed the following:

Device: ModeH264_VLD_NoFGT

Thanks a lot for the test. But no, your card is enough to use DxVA2, you don't need a more recent card! \o/

Did you try with no OSD and restart VLC?

[swissphoenix]

intel i5 750
ati radeon 5850
win 7 64 bit
Iron_Man_2 < tested this sample

video is laggy always stops for some seconds. vlc is without osd
if i only use cpu everything is working fine

[Jean-Baptiste Kempf]

Thanks for the post.

First try, CPU usage was between 30-40%; restarted VLC and tried again, CPU usage was between 10-20%. Weird.

Sorry to be the VLC n00b here, but from what I understand, OSD is on screen display. What am I missing here and what do I need to do to fix/try again?
ps -eax | grep idiotsProcess | kill - 9

No, this is totally possible.
Thanks for your report.

You are not a n00b
Yes, I would like you to deactivate OSD in the simple preferences (see subtiles & OSD) and restart VLC.

CPU: intel core i7 920
GPU: NVidia GTX 260
Windows 7 x64
OSD de-activated

test with Big Buck Bunny 480p

no problem detected. DxVAChecker detect vlc (DXVA2_DecodeDeviceCreated, vlc, 00:00:10.8472567)
(2% max on CPU load)

test with Big Buck Bunny 720p
no problem detected. DxVAChecker detect vlc
(1-2% max on CPU load)

same way with Iron Man


test with Big Buck Bunny 1080p
big lag (6/10 secondes) between frames
(2% on cpu load) DxVAChecker detect vlc


edit: sound is ok; first 5 second of the film too; but after that just 1image per 10 seconds

edit2: some issues with the fullscreen tool wich sometimes prefer to maximize the window.

Weird.

[Warzone]

same issues with 1080P and H264. did not affect audio.

choppy, slow FPS and tearing because it cant kept up with it lol, much like when I try to play 1080P on my laptop:P

CPU usage was at about 21%-23%.

* Nvidia Geforce 285 GTX
* Intel Core i7 Quad Processor i7-920
* Windows Vista Ultimate 64-bit
* Tested with the Iron Man trailer.

CPU-load is stable around 2-3%. Getting some variations in the FPS. Jumps between 15 and 24 FPS.
