However, he further followed up and stated "custom-cpuopts" needs to be enabled on Gentoo -- as I had it switched-off. As such, something of the following incantation suffices: # USE="custom-cpuopts -sse" emerge mplayer xvmc now works avoiding the sse function. I also got a little more from him concerning the specifics of this bug: "(Concerning clear_blocks_sse function within x86/dsputil_mmx.c) ... it is just not possible to use it with XvMC since XvMC was designed in a way that makes it impossible to use it with SSE (though IMO that would be easy to fix from the XvMC developer side), and FFmpeg developers so far do not want to add special hack that also reduce speed only to support the somewhat outdated/obsolete XvMC. >From looking at the Intel XvMC code it is just a matter of changing XvMCCreateBlocks to use memalign instead of malloc, or alternatively wrapping malloc so it always returns sufficiently aligned memory (e.g. by using some *BSD and their libc instead of glibc)."
