Just noticed that after upgrades mplayer no longer starts up. When running from command line the error message is that it cannot find /usr/lib/libx264.so.112
Checking /usr/lib indicates that the file available is libx264.so.119 obviously after an upgrade of a package. I copied libx264.so.119 to libx264.so.112 and mplayer then starts without any problem.
While this fixes the immediate problem it would be nice to have mplayer look for libx264.so.119 instead of libx264.so.112
