  • An Article on VAAPI?

    Hi Michael,
    Looking on the web, i've found that intel is working on a new video acceleration api, vaapi. While the software is still in the planning phase and article on vaapi would be very interesting. This maybe premature however
    Thanks

    iu am very interesting in this too.

      well, if you'll write about vaapi, i think that it is necessary to explain gallium3d, dri2, Input Redirection, Redirected Direct Rendering, llvm, glucose, ttm, mpx and so on, too. we're going to see several improvements on the x-server which are really exciting...

            Still no news article on VaAPI from Phoronix.com?

            I only found the news article on "A Unified GPGPU API In Gallium3D"
            http://www.phoronix.com/scan.php?pag...item&px=NjMyMg

            Maybe VaAPI could be implemented in Mesa but above the Gallium3D architecture in a similar manor to the one suggested for GPGPU in Zack Rusin's blog; though as a unified hardware assisted video decoding API above Gallium3D written using a state tracker?

            Zack adds that as Gallium3D now uses LLVM (Low Level Virtual Machine) for compiling and accelerating shaders, any programming language could be put on the GPU with "minimal effort
            http://zrusin.blogspot.com/2008/02/gpgpu.html

            Then make VaAPI support mandatory in each Gallium3D based device driver ...maybe a good idea since VaAPI spport is required both in the video codec decoder and the device driver for the graphics hardware?

            PS! a generic XvMC library ('libxvmc') would probably be implemented in a similar way for backwards compatibility for video codecs and device drivers that do not yet feature VaAPI support (which today is most if not all).

            Hope that this new Video Acceleration API will recieve a little more attention from the press in the future
