I've posted the bug here:
http://bugs.gentoo.org/show_bug.cgi?id=281228

Somebody just recently made the suggestion, the function is within ffmpeg's, but from viewing mplayer's source code function "clear_blocks_sse" was added just after 20090530 to mplayer's source.

Now, the person making this suggestion, might be pointing to a variable used within clear_blocks_sse (or other detail) depending on ffmpeg.

Is there a way I can use ffplay to play an mpeg specifying it's built in xvmc codec?

$ ffplay -formats |grep xvmc
D VSDT mpegvideo_xvmc  MPEG-1/2 video XvMC (X-Video Motion Compensation)

Suggestions?
