VLC 0.9.9 & Pixelation in Windows 7 (build 7100)

[mathesar]

Hi I recently installed Win 7 (build 7100) and having issues with blocky / pixelated output in VLC, Ive always ran VLC in WinxP without this issue, So far ive tried changing Video output modes in VLC to Opengl / directx / directx3d etc and nothing seems to be fixing it, I can reboot into XP and the problem goes away (same VLC version & settings) Im guessing this is a videocard driver issue but was hoping another Win7 user might of figured out how to fix it. Thanks.

Edit: Im running a geforce gtx260 with latest official drivers.

I found this pic in another forum which shows the exact effect im seeing, unfortunately his solution didnt work for me (changing output to opengl):

Driver issue. DirectX output with or without Overlay video output should work correctly, but DirectX output disables Aero.

Yea even when it does disable Aero for DirectX its still pixelated. Whats wierd is the pixelation problem doesnt exist in windows media player.. So I wasnt sure if vlc or video drivers were to blame.

[VLC_help]

WMP uses EVR video output. All EVR programs should work correctly. VLC uses Direct 3D by default under Windows 7 because of the bugs in ATI and NVIDIA drivers, it goes pixelated (some Windows XP drivers work correctly).

Ill just have to stick with windows media player then, Thanks for the replies!

hi all i do bench for ati user (i had a hd 4850)

-ati ccc vista32 8.11
-ati ccc vista32 8.12

i'm running with9.1 and i think for now it's the best for my card ^^

Well, so something changed weirdly in ATI drivers, then?

[DJMANPS2]

Yes but not only on ati driver i read a lot of similar case with nvidia driver.
i think the dev of this two company are working hard to make her driver compliant with wddm 1.1 for the ms whql certification but they use trick with dx flags or some sh** like that and they cause trouble with lot application they render video.

again sorry for my english i now is so bad

I'm having the same issues with VLC, blocky/Pixalation with 64bit version of Windows 7.
Not what to do, watching movies is blah. WMP is still also a little blocky, so there must be an issue somewhere.

WMP in Win7 plays perfect here its just VLC outputting pixelated video. Im dual booting WinXP & Win 7 and VLC in XP runs without pixelation. Ive tried every setting I can think of in Win 7 without any luck.

Same thing running a fresh install of Windows 7 build 7201 with a Gforce 8800gts with 185.85 drivers. Tried 0.8.6, 0.9.9, vlc-1.1.0-git-20090525-2206-win32.exe and vlc-1.0.0-rc2-20090603-0005-win32.exe with identical results regardless of the version of VLC used.

In Vista switching to OpenGL works. On Win7 though Direct3d is very pixelated and there's tons of smearing on interlaced video. With DirectX and opengl video, it's either pixelated (Divx and Xvid encoded files) or it's smooth but all the reds are shifted to blue so people all look like Smurfs (h.264/MPEG-2 files, although sometimes they are pixelated as well without the blue hue).
I've also tried VLC on a HP Slimline PC with some Intel integrated graphics chip and my file server which has an old Radeon 9700 card (both using drivers from Windows Update on the 7201 build of Win7) and video is pixelated with any output (but no blue shift on those) regardless of the format.

Running in compatibility modes for XP and Vista and disabling Aero doesn't change anything.

The joys of a Beta OS

had same issues with VLC 1.0.1 and WMP Classic, i uninstalled Nvidia driver and put the 182.08 which is official a Vista Driver and all runs smooth now, no pixeled Videos in WMP Classic and VLC

im running a 250 gts

@oli17: do you have Win7 32 or 64?

[oli17]

sorry forgot to say that im using windows 7 x64 dont know if it works in 32

[Jean-Baptiste Kempf]

http://nightlies.videolan.org/build/win ... 1019-1828/ will solve the issue.

C'est OK, il n'y a plus de pixel sous Seven avec cette version 1.1
Peut-elle être intégrer dans une prochaine version de VLC par exemple dans la 1.0.3 sachant que Windows seven ne sort que dans 2 jours ? Car il me semble que VLC 1.1 n'est pas pour aujourd'hui.

Sinon bravo
