I make this thread with the intention of gathering information on the current state of usability of UVD and UVD2 in linux.

I am a novice when it comes to understanding driver architecture and difficulties concerning them, so if anyone would like to give an introduction to why UVD / UVD2 as of now is not useable, it would be much appreaciated.

I'll come with the first (obvious) update:

In fact, the official release of Catalyst 8.10 doesn't have a whole lot worth talking about. It does have UVD Linux support enabled to accelerate video playback via the XvMC extension and their own HD video interface. However, all attempts at using XvMC with mplayer have failed thus far and AMD has been mum on how to actually use this feature. This looks like another feature we'll need to wait until Catalyst 8.11 to find out more.

Now for some of my own questions:

1. Will it ever be possible to use this feature? Will I ever be able to make the GPU decode my x264 encoded material?

2. How will programs make use of this feature?

3. As video tearing is a common problem at the moment many people are using built in graphics or a nVidia add-on card instead (in case of for example a 780g chipset) - will it be possible to make use of UVD when you are using another video card?

Hope these questions make even remotely sense for you guys!
