This worked for me:
ffmpeg -i test.flv -vn -acodec copy -f adts - | ffmpeg -i - -vn -acodec copy -absf aac_adtstoasc -y test.m4a
I think the trick is choosing the right output format from the first ffmpeg command. It needs to use a muxer that doesn't require seekable output, so adts seemed like the right choice.
