How do I find command list for MPlayer video & audio filters

[Hood]

Hey guys,

anybody please guide me to how to get the commands and their purpose for use with SM Player.

Like Mplayer options tab in advanced panel as there are spaces given for the user to apply extra audio and video filters through inputting commands there.

Thanks.
