One issue is that there's no EGL / GLX API yet for this. VDPAU has time-based presentation, but that isn't fully plumbed through yet either but internally converted to a target display refresh counter. Therefore, video players are currently de facto relying on fixed refresh rate. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
