Guillaume,

It only appears to happen when compiling with gcc 4.4 in 32bit mode.
I've ran into this situation about 2-3 weeks ago using Fedora rawhide.
As compilation of mplayer just quit working after gcc 4.4 was upgraded.
I've went back several versions in SVN, even to known working (ie could
compile) versions and so far it seems to be a register starvation issue
with the new GCC.

For now disabling internal liba52 seems to be one workaround for
compiling 32bit mplayer with gcc 4.4.
