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,
