Inside mplayer? - NO!

Download and install MediaInfo_linux_cli (google it against "sourceforge").
First of all make various labeled configuration (profiles) in 
"~/.mplayer/confg" for your desired action.
Then make starting script where:
1) make report about file with MediaInfo and write it to /tmp directory 
then grep or gawk it for desired parameter;
2) use grep/gawk output to chose desired configuration;
3) run mplayer with "mplayer -profile profile_name $1" where 
"profile_name" is chosen on base pt.2).

That's all
