    As UVD provides full bitstream acceleration you should never see high CPU load.

    @Qaridarium
    The open source approach will probably not use the video decoding hardware, but shaders, and this won't...

    More importantly it allows the X server to run without hardware access, i.e. as a user instead of root.

    According to NVidia developers the drivers already implement most of the features of what's...

    There is no "approved" or "correct" way, especially when it comes to Linux. APIs and interfaces change *all the time*. And there isn't just Linux, but FreeBSD and Solaris as well, which are...

    Read again.



    What for? NVidia's driver already has excellent acceleration w/ NVidia's own framework.



    Again, why? NVidia already provides fast 2D acceleration and did so before EXA saw...

    With AMD's Windows drivers, H.264 decoding via DXVA is restricted to level 4.1, while NVidia's drivers can decode up to level 5.0 (like VDPAU). I guess this is just a software issue though.

    It's...

    It's time the kernel separates drivers/optional subsystems and core. Oh wait, that would require stable APIs, wouldn't it? :)

    I thought Plymouth was supposed to be a slim bootsplash, not an abomination with all features you can cram into that nobody needs. Also it's not like a splash screen is anything particularly...

    Yes, sure, gradient rendering can be accelerated. In the worst case the fixed function hardware doesn't support it and you need to use shaders, but that isn't a problem, it just means more work.
  11. That's exactly my point and that's why the...

    That's exactly my point and that's why the missing gradient acceleration might be a problem. With the NVidia example, if you have some gradient rendering in your pipe, everything will slow down...

    Well, it's a bit strange. In synthetic benchmarks (like done by Phoronix), the NVidia drivers perform extremely well. A few quick benches (w/ JXRenderMark) show that XRender performance is a lot...
  13. NVidia's later binary drivers perform very well...

    NVidia's later binary drivers perform very well now, at least in my experience. A benchmark would be still be interesting, of course.

    It's only possible to use a fixed blending equation (or does it even support chroma-keying only? I'm not sure... would be great if the documentation sucked less... seriously). OpenGL of course is...

    Post-processing, especially deinterlacing better than bob; blending in VA-API is not very powerful.



    No, I'm not. :) I'm aware that only NVidia and S3 implement VDPAU at the moment, but where...

    Oh, come on. No it isn't working until AMD opens XvBA.



    Just curious: I think it'd be nice to have *one* API for video decode acceleration instead of multiple ones on Unix and in my opinion,...

    Yes, but you can't blame the renderer/video output. Adding noise etc. is usually done with video filters, and traditionally these run on the CPU. For video decoding acceleration this means you'll...

    No, VDPAU allows the frames to be reused by OpenGL and it's possible to download them to the host system as well, for later display with the renderer of your choice.

    By the way, what kind of...
