    Phoronix: NVIDIA 331.20 Supports New Kernels, NvFBCOpenGL

    The NVIDIA 331.20 Linux graphics driver has been released today. The NVIDIA 331.20 Linux driver has a workaround to support the Linux 3.11 and 3.12 kernels along with introducing NvFBCOpenGL. The new NvFBCOpenGL is for NVIDIA OpenGL frame-buffer capturing that's high-performance and low-latency...

    " Sadly, however, NvFBC and NvIFR are private APIs... While NVIDIA is nice sometimes like in the case of making the VDPAU video encode/decode API open to the community, NvFBCOpenGL is not. Anyone interested in the interfaces for using this new NVIDIA library must contact the company for details."

      Direct recording would be super useful for what I'm doing. If its performance is better than glc, it would be awesome. Though it's weird that they have a library, and no actual way of making use of it...

      Also, yay, new kernel support, just in time for openSUSE 13.1.

        Hmm is these new apis for shadowplay or what? If It is, it surely needs keplers hardware h264 encoder.

        But then again Michael didn't quote the rest:
        NvFBC and NvIFR are private APIs that are only available to approved partners for use in remote graphics scenarios. Please contact NVIDIA at GRIDteam@nvidia.com for more information.
        So is this the used tech that streams over net like computer to shield.

          To those of you on bleeding edge with Metro LL

          Don't bother setting this driver up, it breaks the game.
          At least it did for me.

            Pretty sure this is a feature Valve requested for SteamOS.

              Wonder how they'll allow for Steam Machine with Intel/AMD hardware in the future if they can't use the Steam OS streaming capability.

                Actually you can (easily) record OpenGL with a program called Simple Screen Recorder: http://www.maartenbaert.be/simplescreenrecorder/

                  Wow, that looks really nice. I'll have to try it. Too bad it doesn't support PulseAudio yet.
                  Though it still doesn't match the efficiency of doing all of it on GPU, I'm pretty sure.

                    On my case i test simplerecorder but i try some capture programs, but after testing i stay with vokoscreen, capture without minor problems on my machine (I capture only video but impact fps seriously: 30 or more percentage depend title)

                    This is my video list reproduction with some uploaded videos about wine testing

                    sorry for my english, im spanish


                    Back to theme, im thinking about this

                    The NVIDIA OpenGL-based Framebuffer Capture (NvFBCOpenGL) library is all about high performance and low-latency captures while also having support to encode the composited frame-buffer of an X11 output
                    This seems come nvidia shadowplay equal to linux???????


                    Sadly this upgrades its privative but talking seriously, NVIDIA dont want free technologies but if possible using how strategy marketing and this situation i dont think so change in future but privative driver offers more features, on my case performance and features is more important how is driver is free or not

                      Same here. Just says Steam: Application Load Error.

                      But downgrading to Nvidia 325.x driver makes it work again.

                      Strange, because Xpander69 (on YouTube who does a lot of Linux gaming vids) is running 331.17 beta drivers and the game clearly runs for him.
