Yes. I specified a non-exists driver, mplayer quit early, complains
not find the non-exists so.

I've did the test without compiz, it seems not make any difference.

I add the path "/usr/lib/libXvMCr600.so" to /etc/X11/XvMCConfig, but
mplayer seems not invoke it (No r600 in strace or /proc/pid/maps).
Maybe I should try a newer version of mplayer.

Yes, some r600-related patches are backported from the master branch.
