Well, yes.
It does actually not make a difference if you also specify the
audio-codec (-acodec pcm_s16le). The format is the same for both.

There's some (undocumented) feature: pass '-d' as first argument to
ffmpeg. That makes ffmpeg shut up and not touch termios; it still works
with writing data to stdout:

 ffmpeg -d -i /some/file -f s16le -c 2 -ar 44100 pipe: | ...

kill -TERM `pidof ffmpeg`

HTH,
