Ok, for an htpc based off windows it would be a competitiv solution. But it would be senseless for Linux (XBMC).
There would be no hardware accelerated gpu and the cpu is too weak to decode 1080p

so then, please enlighten us why exactly you say this as a fact

I think it is a common misunderstanding that AMD (and it's drivers) aren't capable of hardware acc. while Mplayer (and VLC Player) proofs that this is no problem.

and xbmc. we support va-api, possibly a bit glitchy, but we do support it.
- sylvio2000 - 2010-11-17 13:53
I always thought that vaapi is not yet ready (stable) to use with XBMC?
Everybody says that if you want hardware accelerated gpu decoding in Linux (XBMC) you should buy an Nvidia card because of VDPAU.
Therefor I think this system would be senseless (for XBMC and 1080p) on Linux.

nvidia and VDPAU is recommended for *painless* GPU-assisted HD acceleration. VAAPI for AMD/ATI makes good progress, so there's definitely enough "sense" in the Fusion platform even with linux, but we've had a lot of talk about this already in this thread.

Ok, I dont wanted to state this as a fact
But to sum it up, atm the better solution is VDPAU and zacate would not be the ideal solution (although I would prefer AMD
)
- Hannes The Hun - 2010-11-17 14:15
yeah, that's about right
- Robotica - 2010-11-17 14:15
If you look at the experiences all over internet it is no problem to have hardware acc. with Mplayer (only since recently and not that perfect as VDPAU but workable). XBMC doens't have a good track record like Mplayer since there isn't much development. Have a look at TRAC: http://trac.xbmc.org/log/trunk/xbmc/cores/dvdplayer/DVDCodecs/Video/VAAPI.cpp?rev=29053
This is the case while (XBMC) users reported workarounds and fixes for the problems.
However, VAAPI is actively developed since then: http://www.splitted-desktop.com/~gbeauchesne/mplayer-vaapi/ and even Xvba is developed: http://www.splitted-desktop.com/~gbeauchesne/xvba-video/ Same for libva: http://www.splitted-desktop.com/~gbeauchesne/libva/
Some related and unsolved XBMC problems:
http://forum.xbmc.org/showthread.php?tid=81685
So for now, VAAPI of libva aren't the problem; XBMC is. But that is open source. It takes time for quality patches to get this working. Currently, teamXBMC has no interest in developing this feature and therefor some competitors are ahead.
And knowing history, I can imagine that there is no interest in workarounds and quick fixes.
- sylvio2000 - 2010-11-17 15:33
Mmh, maybe I havent found the answer, but is there any reason for teamXBMC to not develop vaapi support?
I dont want to blame anyone. You guys do a great job. I just would like to know why?
