[MPlayer-users] [feature request] -sid/-slang/-aid/-alang list or help parameters

[Robert Gomułka]

Hello,
I've used 1.0pre3 version of mplayer, but don't think that such a feature was 
requested.
When you want to use one of those options, but don't know which subtitle/audio 
languages are on a DVD, documentation suggests using mplayer with -v switch 
and looking into the output. Although it should work, it is also very 
uncomfortable for ordinary user. -v produces many lines of output, so finding 
the specific one can take a lot of time.
In my opinion above switches should accept additional parameter - help or 
list. When specified,  it should list available languages in form similar to 
-ao help or -vo help.
Best regards,
Robert
