[FFmpeg-devel] lavfi: expected behavior for multiple filter definitions

What is the expected behavior of:
ffmpeg -i in.mp3 -af aresample=8000 out1.mp3 -af earwax out2.mp3

AISI each output should have only the preceding -af applied to it, and not the 
others. Note that currently this simply leads to applying the second -af to 
out1.mp3 and not filtering out2.mp3 at all. Also note that I ask this question 
because output_files[] parameters are currently inaccurate due to being set 
_before_ configure_audio_filters().
