I've updated mplayer in Cauldron SVN to the latest snapshot from upstream, and it still fails to link when x264 is enabled, apparently since this commit to mplayer: http://svnweb.mageia.org/packages?view=revision&revision=1712114 It's not apparent why, although that commit added --enable-x264 to configure, so maybe it was silently not working before that, and perhaps the issue started with the last update to x264 (r1602603).
I fixed the logic behind enabling or disabling x264 support in .spec. It didn't work as expected as mplayer's configure --enable-x264 is broken. Better to leave x264 check to auto mode and disable it explicitly only when x264 support is also disabled in .spec. As a side note system ffmpeg devel pulls x264 devel ATM so actually x264 support was enabled previously even when %build_x264 was set to 0 in .spec.
