Tux Machines (TM)-specific
It was just over the weekend that we reported XvMC and VDPAU may come to the ATI R600 Gallium3D driver that would allow those with Radeon HD 2000/3000/4000/5000 series graphics cards (what's supported by R600g) to enjoy accelerated video playback using GPU shaders beyond just the limited X-Video extension. This work was being done by Christian König and today he has one hell of a surprise: it's to the point that today you can try out the code and it should work for XvMC! Yes, that's the case, I just read the email twice and am now scurrying to test out the appropriate ATI DDX and Gallium3D driver.
This support hasn't yet perfected, but the first few frames of the video playback may be buggy and on some tries the initialization will fail, but based upon the speed König is going, this is amazing progress.
