Per your recommendation, I tried the following:
filtering_audio test.mp4 > test_audio
ffplay -f s16le -ar 8000 -ac 1 test_audio
but with no better luck than with:
filtering_audio test.mp4 | ffplay -f s16le -ar 8000 -ac 1 -
Where to search "trac tickets"?

Possible. Try to put the output in a file, and then read it with ffplay. IIRC
there was an issue with Windows and pipes (and I'm not sure cmd.com really
supports them), you may want to search in trac tickets.
