mplayer: extract audio to PCM to stdout - …
https://www.linuxquestions.org/questions/linux-software-2/mplayer-extract-audio-to-pcm-to-stdout-617451/
I would to have mencoder/mplayer read a video file and output just the audio part as PCM (raw 16 bit) to stdout. The -dumpaudio option does not do this. The -dumpaudio option dumps the audio as is, not converting from the input codec to a "proper" raw format. In a perfect world I woudl type something like this:

-dumpaudio (MPlayer only) Dumps raw compressed audio stream to ./stream.dump (useful with MPEG/AC-3, in most other cases the resulting file will not be playable). If you give more than one of -dumpaudio, -dumpvideo, -dumpstream on the command line only the last one will work.
Python Subprocess stdout PIPE for mplayer processes ...

Try sending 8 KB of line breaks. For readline (), you need an end-of-line character ('\n') but mplayer normally writes its progress information on the same line (with '\r'). It must be possible to get in- and output of a subprocess directly (without buffers) as terminal applications can print output immediately.
bash - Write mplayer's output to fifo and read it - Stack ...
https://stackoverflow.com/questions/13111633/write-mplayers-output-to-fifo-and-read-it
mplayer <url> | stdbuf -o L grep ICY > .rp/fifo If that doesn't work, moar is bettar! stdbuf -o 0 mplayer <url> | stdbuf -o L grep ICY > .rp/fifo And if that still doesn't work, then it's possible that mplayer isn't writing to stdout, but directly to /dev/tty. In which case, you will need to read up on expect(1).
stdout to mplayer - Ask for Help - AutoHotkey Community

mplayer has a slave mode which allows you to send it commands over stdout. Is there a way to do this with autohotkey? Here is the mplayer documentation for reference.

http://tivo-mplayer.sourceforge.net/docs/mplayer-man.html
-dumpfile <filename> (MPLAYER only) Specify which file MPlayer should dump to. Should be used together with -dumpaudio / -dumpvideo / -dumpstream. -dumpstream (MPLAYER only) Dumps the raw stream to ./:stream.dump. Useful when ripping from DVD or network. -dumpvideo (MPLAYER only) Dump raw compressed video stream to ./:stream.dump (not very usable).
3.4. Streaming from network or pipes - MPlayer
http://www.mplayerhq.hu/DOCS/HTML/en/streaming.html
Once you succeed in making MPlayer play your favorite internet stream, you can use the option -dumpstream to save the stream into a file. For example: mplayer http://217.71.208.37:8006-dumpstream -dumpfile stream.asf. will save the content streamed from http://217.71.208.37:8006 into stream.asf.
