Multimedia, AV The sweet smell of competition is lingering in the air. That sweet smell which indicates that somewhere in the vicinity a company is working on actually improving a product so we can all benefit. This time around, it's Adobe, delivering the first Flash 10.2 beta. Prime feature? Complete hardware acceleration of the entire video pipeline - fully cross platform, cross-form factor. Cross-platform! There's a catch, though.

Video Decode support through XvMC, VDPAU and VA-API APIs using the 3D engine (as opposed to the UVD dedicated hardware) is a work-in-progress for the open source Gallium3D drivers for AMD/ATI chipsets R300 through R800.

It is not possible at this time for the open source drivers to utilise the UVD hardware which is in R600/700, Evergreen and N.Islands chipsets because AMD/ATI have not released the programming information for this part of their chipsets a yet. As I understand it, there is significant doubt that ATI/AMD will ever be able to release this information due to concerns that this will also give clues to the DRM provisions which are also part of UVD. If that is the case, the video decode work which is underway using the 3D engine (shaders) might become the only option for the open source drivers, even for chipsets which include UVD.

Sounds awesome, reminds me very much of Light Spark:

Which is using a combination of LLVM and GLSL to hardware accelerate video play back plus a whole host of other Flash functions. I agree, the best thing that the *NIX world can do is build on top of GLSL and updating Mesa to OpenGL 4.1 compliance than trying to deal get access to proprietary video decoding features.

With that being said, the one thing Apple has done well is build on top of GLSL really cool features such as Core Animation etc. which provide a high level API than having to leave up to third parties to redesign the wheel.
