I ran:

mplayer -osdlevel 3 -vo vaapi big_buck_bunny_720p_stereo.ogg

For me, the OSD text is solid green, with hard edges.

If you use "-vo gl" or "-vo xv", the OSD is solid white text with a black
border around it.  I presume that it's supposed to be white with vaapi as
well, but I guess I'm not entirely sure.

It's possible that the optimization doesn't affect the palette as long as
you never use sample_c with the paletted textures.
