mplayer -msglevel all=-1 doesn't make it completely silent!

I'm trying to open mplayer to play video without **any** terminal output using this: mplayer -msglevel all=-1 /path/to/video also: mplayer -really-quiet /path/to/video but it doesn't make it completely silent! and these are printed to output: [flv @ 0x9a5d100]Estimating duration from bitrate, this may be inaccurate [ass] Init [ass] Updating font cache How can I make mplayer completely silent? Thanks
