[FFmpeg-user] stream specifier from -drc_scale option ?

[pehache]

Hi,

-drc_scale <value> is an AC3 decoder option for dynamic range 
compression, which must be placed before -i <input>

Is it possible to append a stream specifier if one want to selectively 
apply DRC to some streams, e.g. -drc_scale:3 <value> to apply DRC only 
to the stream #3 of the input file ?

Thanks
