    Phoronix: Gallium3D VDPAU State Tracker Gets Ready For Action

    Christian König of AMD has shared his plans for completing work on the VDPAU state tracker for Gallium3D. This Gallium3D state tracker allows for NVIDIA VDPAU video acceleration using GPU shaders on open-source hardware drivers such as Radeon and Nouveau...

    Great! If we're lucky we might have usable VDPAU acceleration in open-source drivers by this Fall.

      Awesome!

      Absolutely great! This has been THE feature for me in the open source drivers that was needed!

          VDPAU is not only an API for decoding - it also includes a presentation API that is much, much more powerful than Xv. These commits are all about the presentation part of VDPAU. There still is no useful decode acceleration support available.

            Wait what ? Page-flipping / tear free on secondary displays ? Really ? For sure ?
            I always thought that there was an limitation in the underlying drivers that prevented this. It'd be awesome to have this (does it also work on secondary cards ?). I'd be grateful for references / comments on this ...

              Hope you guys realise, you absolutely need to tighten GPU acceleration to powermanagement? A machine that is using just even more mA´s due to "acceleration" could leave a bad impression. Ty.

                Very nice! Can't wait for the h264 decoding!

                Please don't forget to add 10 bit decoding as well!

                  Damn those Nvidia binary blobs that are constantly trying to take over the world... OSS FTW! </sarcasm>

                    +1. We want to see performance tests of this!

                      which codecs are supported by the state tracker???

                      webm???

                        Mpeg1 and Mpeg2 as a starting point. But h.264 and webm are worked on.

                        Also, qvdpautest freezed my X on the threaded test.

                          Can't say that I care for much else than *264 anymore. But you never know when they come in handy.

                            Mpeg 2 is really important for me. All terrestrial HDTV is broadcast in Mpeg 2 where I live. Although h264 and webm definitely are welcome as well.

                              Same here. My mythtv box plays a lot of MPEG-2 and any cpu cycles that can be put towards deinterlacing 1080i content would be helpful until that is also worked out on the gpu. Also the benefits of the presentation abilities over XV will be much welcomed.
