Hi, In the past there has been a topic for VAAPI, but I guess that it is a bit old and wanted to bring up this whole thing again...
Lately there has been a new libva release. I tried it on my AMD64 laptop with GNOME3 and an ATI card, it looks pretty solid, I recompiled VLC enabling the vaapi USE flag and now I can see my HD videos in a much more heat-free way. I see that many distros offer VLC GPU acceleration with VAAPI out of the box so I was asking myself "why shouldn't Sabayon do this"? I recall VAAPI to be quite problematic but I think it would be worth a test on Limbo. I looked a bit deeper at the libva ebuild and noticed these USE flags: IUSE="opengl" VIDEO_CARDS="dummy nvidia intel fglrx" opengl, intel and dummy are enabled, which is fine I guess, nvidia and fglrx USE flags bring vdpau and xvbc as post-dependencies with libva, which, in my opinion, is not a very good thing, since we could have xvbc on a Nvidia card and vdpau on an ATI cards, so those USE flags could be disabled for that package on Sabayon. I see from "equery hasuse vaapi" that ffmpeg has a vaapi flag (currently enabled) and even XBMC has one, in the newer version available on portage. -- Lorenzo Cogotti
