Hi All,

I'd like to send my laptop's sound to 2 fifo-s at the same time in order to
read from that fifos later. For some reason if I read from those fifos,
nothing happens:

ffmpeg -i fifo1 -s 0 -t 5 out1.wav
ffmpeg -i fifo2 -s 0 -t 5 out2.wav

This is how I create the 2 fifos:


mkfifo fifo2 2>/dev/null
mkfifo fifo2 2>/dev/null

ffmpeg -f alsa -i hw:0,0 -f wav pipe:1 > fifo1 -f wav pipe:1 > fifo2

exit 0
