VLC 1.1.1 + Catalyst 10.7 on 3xxx

[BigBroly]

The GPU acceleration with the new Catalyst 10.7 is still stuttering like crazy on any video I play. Is anyone else having the same issue? Are there settings I'm missing somewhere?

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

Hi, I dont' have the stuttering problem you're talking about but I don't really know if vlc 1.1.1 really is in dxva.
The problem is when I try to use "noise reduction", "automatic contrast" or "gamma" in the Ati control center, the effects are not applied to the video although it works with mpc-hc in dxva2 mode...
In fact, I don't even know if VLC is in dxva mode or not...

Is there something to activate in the preference ? is there a simple way to know if vlc is in dxva mode or not ?

My cpu Core i7 (720) usage is between 7% 11%
Graphic card : ATI Radeon HD 5870 Mobile

Hi spigoule,

Other than enabling GPU acceleration in Tools > Preferences > Inputs and Codecs, I'm not really sure how to tell it's in DXVA mode.

[spigoule]

Thanks BigBroly,

Enabling gpu acceleration in the preferences helped me. I thought hardware acceleration was activated by default.
Now my video seems to be decoded by gpu as my cpu usage is between 1 and 4 % and I got no stuttering at all.

But I still can't make the video filters from the ati control panel work. Do I need to select another video output ? Does EVR mode exist in VLC ?

[Jean-Baptiste Kempf]

VLC doesn't use ATI filters.

Re-formatted my computer, installed VLC 1.1.1 and Catalyst 10.7 on a clean install of Vista, and I'm still getting the same result with the GPU acceleration enabled. Video is very laggy/choppy/skip many frames and is pixelated. I'm not sure what I'm doing wrong or if I'm missing something, but it just doesn't seem to be working.

Same here, choppy and pixelated.

what are you guys talking about! i have crappy hd3200 and it works brilliantly! i couldn't play my 1080P or 720P 60FPS Kodak zi8 clips (H.264 MOV) very complicated format on windows but Now i can play them smoothly. Same goes for 1080P MKV files...couldn't before but can now!

windows 7 64-bit, ATI HD3200 10.7

Guys, calm down, if you have a Radeon 3xxx, it might work, or it might not.
This will depend on your CPU and on your motherboard.

[guser]

nice! no support for ati 3xxx :\
ffs damn amd/whoever fault it is!

Take it easy, man! If ATI says "it's not supported on HD3000 series", it does not mean it will not work. They only won't guarantee you it will.
If it works on your PC, yay! Good for you. If it doesn't, ask ATI what they can do for you. Ask if there will be support for your card, or buy a newer model.

In fact, the ONLY card it will work from the HD3000 series is the 3200, because it has a UVD2 lite in it, while the other have UVD+

Therefore, this is expected.

so that's whats going on check out Unified Video Decoder on wiki

Yep, enabling GPU acceleration in VLC for ATI 3xxx series will cause lag and distortion to the video.
So it is ATI or a VLC issue ? Not quite sure from the answers given here.

[VLC_help]

ATI. The same code should work with all display adapters.

ATI drivers for 3xxx doesn't provide the mode that VLC 1.1.x needs.

Whose fault is it? It depends of your PoV

I still don't understand why Media Player Classic decodes h264 by GPU, but VLC with turned on GPU acceleration do not!

I have:
Windows Vista 32
Ati HD3410
Catalyst 10.11
CPU - AMD Athlon

[Jean-Baptiste Kempf]

Because VLC requires full decoding and your HD3410 doesn't support full decoding in DxVA2
