ffmpeg stream and record at the same time

Hi,

I'd like to stream and record my laptop's audio input at the same time.

Streaming works perfectly with this ffserver config file:

Code:

HTTPPort 4444

HTTPBindAddress 0.0.0.0

MaxHTTPConnections 10

MaxClients 10

MaxBandwidth 1024

CustomLog -



<Feed audio.ffm>

File /tmp/audio.ffm

FileMaxSize 100M

</Feed>



##################################################################



<Stream audio>

Feed audio.ffm

Format mp2

Audiocodec libmp3lame

AudioBitRate 56

AudioChannels 2

AudioSampleRate 44100

NoVideo

#StartSendOnKey

</Stream>





<Stream stat.html>

Format status



#ACL allow localhost



FaviconURL http://pond1.gladstonefamily.net:8080/favicon.ico

</Stream>

Than I start ffserver:

Code:

ffserver -f /etc/ffserver.conf &

And start ffmpeg:

Code:

ffmpeg -f alsa -i hw:0,0 http://localhost:4444/audio.ffm | tee arecord -f cd -r 44100 -d 10 test1.wav

The streaming works nicely but tge test.wav file never gets created for some reason.

you cannot tee into arecord that way. And also I cannot think arecord can handle stdin like this.

I know, that's an issue, thanks.
There must be a workaround for this. I'm testing with a 2 fifos now:

Code:

#!/bin/bash



s="streaming"

r="recording"



cd /tmp/ || exit 1



if [ -p "$s" ]; then

        rm "$s"

fi

mkfifo "$s"



if [ -p "$r" ]; then

        rm "$r"

fi

mkfifo "$r"



ffmpeg -f alsa -i hw:0,0 -f wav pipe:1 > "$s" -f wav pipe:1 > "$r"



exit 0

And then I would record and stream from the 2 fifos:

Code:

ffmpeg -i /tmp/recording -t 00:00:10 /tmp/test.wav

Code:

ffmpeg -i /tmp/streaming http://localhost:4444/audio.ffm

Here is the output of ffprobe for the 2 fifos:
