ATI Catalyst 11.5 breaks H.264 GPU - 11.6 solves it

ljbade · Postby **ljbade** » 11 May 2011 00:39

I just installed ATI Catalyst 11.5 and now when I enable GPU acceleration in the preferences the video playback is broken.

The video flickers between green and the same frames in a loop. Some other videos just show black.

I discovered it when someone else said it was also happening on their machine.

Can other people here with ATI Catalyst 11.5 installed verify this bug?

To enable GPU acceleration: Tools menu -> Preferences -> Input & codecs button -> Enable Use GPU acceleration checkbox
Then play a file with H.264 video.

My setup:
Windows 7 SP1 x64
XFX ATI Radeon HD 5850
Catalyst 11.5 final (Driver Packaging Version: 8.85-110419a-118230C-ATI)
VLC 1.1.9

I have exactly the same bug on my laptop, running Windows 7 SP1 with Catalyst 11.5 on a Mobility Radeon HD3200 with VLC 1.1.9.

Did you try 11.5a hotfix?

I did, but there was no improvement, I don't know if there's much of a difference between the desktop and mobile driver releases though so maybe the desktop 11.5a would fix it.

Same thing here. Dell Inspiron 15R, ATI 5470, Catalist Mobility 11.5. When enabling GPU acceleration, H264 video displays black screen. IF disable GPU acceleration, video displays normally. Other types of video seem not to be affected.

Anyway, a big Thank You to the VLC team for a very clean player!

Yes, this is confirmed with AMD. This is a regression on their side.
They are investigating.

same here.

Got a HD 4670 with cat 11.5 and 1.1.9 vlc, this makes my screen go black, and it's fine when i turn off the GPU acceleration.

Still not working for me. Hopefully Catalyst 11.6 will address this.
