AMD Releases Open-Source UVD Video Support
Phoronix: AMD Releases Open-Source UVD Video Support
Within the next few hours AMD will be publishing open-source driver code that exposes their Unified Video Decoder (UVD) engine on modern Radeon HD graphics cards. This will finally allow open-source graphics drivers to take advantage of hardware-accelerated video decoding. Read more details in this Phoronix exclusive.
If you'd published this a day (or two) earlier, I simply wouldn't have believed it...!

But anyway, thanks AMD!

There's no support for commonly used DRM / content protection techniques. So yes, no HDCP.

As a general rule, TVs support HDCP, but they don't require it in most cases. Usually it's the device actually producing/playing the content that would refuse to produce output if HDCP isn't required (such as a Bluray player).

As long as you're not trying to play back encrypted Bluray discs with software that requires the encryption, you'll be fine.
Oh OK, I think I understand now. So it is the player that will dictate whether or not the content requires HDCP. Which if the content is decrypted then even that requirement could be removed.

I don't even care about 3D games, but please AMD consider OpenCL... because even though your processors are not the best nowadays your graphics cards are way better than those from Nvidia for GPGPU. I would really love to buy a 7990 if it had proper OpenCL support.
I am an nvidia user, but I can only say, good job amd , this is a great news for the opensource world
