    Phoronix: A 3D Understanding Of ATI's R600/700 Series

    Late last year AMD had released R600/700 3D code and in late January had then released R600 3D register documentation to begin work on an open-source driver stack supporting the latest ATI Radeon GPUs with 3D acceleration. One of AMD's partners in this open-source work has been Novell, which wrote an open-source utility to begin sending 3D commands to the GPU in a very primitive form and to analyze the different operations...

    From the first minutes of the video it seems it is pretty useless again. Very bad hissing and sound only on the left channel. And you cannot read the slides. But better than nothing...

    I suggest you to look at the real slides from matthias' blog

    while listening to the "vid". And again flash crap. What a pity!

        Flash

        Please, for the love of god, no more Flash. You are documenting an open source conference, you could at least use an open codec. Moreover, the audio is unusable in this video. At least if we had a real video file someone could extract and cleanup the audio.

          Gnash and swfdec are Free Software and can both run SWF files, including those that play FLV videos.

          FLV is an open specification. Please quit whining about nothing.

            Strictly speaking, the FLV container format is open. The codecs which are used with it, however, are heavily patent encumbered. Moreover, it took me over ten minutes to finally grab the FLV itself, only to find that my usual tools for video manipulation are useless with the format.

            All of this could be easily avoided by simply putting up a Theora file up alongside the Flash video.

                For those who care, the FLV can be found at http://blip.tv/file/get/Phoronox-08r...ip.tv&source=1.

                  The flash app does not work here with gnash.
                  For a normal video there is no flash necessary. So it is simply stupid to use, because you depend on it.

                  There are flash video players that work with gnash, but this one used here does not. There should be at least a link to the normal video.

                  Stop whining that we complain about that useless crap.

                    Uh... Several answers have been given out. A FOSS codec means it's useful to us, but not to the other communities out there- and we'd like to show everyone what we're accomplishing as much as anything else (and moreover, not everyone's reading this on Linux but Windows machines, some poor souls are stuck on Windows 7 or XP because of circumstances like work machines (or in deanjo's case, the only way he can interact with his computer- he's driving a repurposed Netbook with Dragon Naturally Speaking (There's an area we probably ought to look into fixing next... ). Severe burns on his hands and he's lucky to be alive, if the pic he showed in another forum is any indication of his injuries in the mishap...). While Ogg Theora's nice, it's not used much outside of the FOSS crowd right at the moment. If you don't want to use Flash I suggest nabbing the video via one of the Firefox Flash grabbers and either transcode it to a different format or a different container- or just use Mplayer like Kano suggested.

                    Bitching about it gains nothing. If you don't like the circumstance of things like this, you can always can-opener the damn thing (That's what I do) and provide it to someone else. If you don't have those skillsets, that's fine too- just ASK instead of bitching and I suspect someone would be more than happy to accommodate you.

                      It would be nice to have this in ogg/theora, and also better audio quality. Michael, I think you may need to grab a different audio recording setup somewhere, even if you can't sync it exactly from the video. It would help a lot to have clear audio.

                        No firefox - no ff flash grabbers.
                        No link - no way to download vid without searching through the source.

                        It does not have to be Theora. Please just provide a link, and preferably to any other codec than flash. But even that would not be mandatory. Just a link to download it, for those without flash. In the article.

                          Just give us direct links to the files,so we can download the videos and play them with our favorite media player.

                          * Fullscreen flash in a browser runs like a dog on single core machines
                          * Some users just don't want to install Flash or are using browsers that do not support JavaScript and Flash

                          But they all have one thing in common: standalone video players that can play those files fullscreen at full speed.

                            So? I bet it would be very easy for Windows/Mac users to find a way to play theora if they really wanted to. Why should Linux users always cater to proprietary, closed-source software (especially on a site devoted to Linux)?

                              And how's Theora gonna help? H.264 is more widespread and has excellent open source implementations for both decoding as well as encoding.
