My intel video card can accelerate graphics via VAAPI but mplayer and flash only work with VDPAU. I use libvdpau-va-gl to allow VDPAU to utilize VAAPI and so accelerate mplayer and flash with my video card.
mplayer works great this way but Flash is still slow. I'm setting VDPAU_DRIVER=va_gl and terminal output from the browser looks good. Any ideas? Can I benchmark flash performance somehow? - Grant
