bash discover Audio codec used in a file

carl0ski · 01-19-2007, 06:47 PM

Hi

i need to find a way to either save as a variable or display the audio format/codec used by a file

The reason is so i can modify my Mplayer audio output based on whether its
ac3 or mp3/etc

AC3 works best on pass through

Code:

-ao alsa -ac hwac3

but mp3 doesnt work with the above.

basically

Code:

if $audio==ac3
then
output=$("-ao alsa -ac hwac3")
else
output=$("")
done

"Disover what audio codec is- choose output" ; mplayer -fs $output /media/Movie

Try "file" to invoke your filetype magic recognition. May require some new entries in your magic file to work.
