Hello, recent live ebuild uses cdio as default (+cdio) and requires both -cdparanoia and -cddb for it in REQUIRED_USE: cdio? ( !cdparanoia !cddb ) So +cddb +cdio should not be used by default as it will cause blockage.
Created attachment 261759 [details, diff] mplayer-9999-cddb.patch Trivial fix.
Thanks for the report fixed in main tree.
