If I run command

ffplay -t 3 test.aac

it just plays the whole file, instead of 3 seconds. What command would be used to set duration of playback?

It appears that the -t option does not work on all files. I tried this command

ffplay -t 3 test.mkv

and it worked fine. As a workaround this command works for the aac file

ffmpeg -i out.aac -c copy -f adts -t 3 - | ffplay -autoexit -

I would suggest adding autoexit to your command:

ffplay -t 3 -autoexit test.aac

If that doesn't work, I would suggest an alternative (mplayer):

mplayer -endpos 3 test.aac
