[FFmpeg-user] Extract audio stream from non interleaved AVI

Following up a question on StackOverflow which explains the "problem" in
Short version: extracting audio from a non-interleaved AVI is slow, the
whole file (i.e. video stream) has to be read to get to the audio (I
assume this is what's happening).
On a properly interleaved AVI it's near instantaneous.
The question revolves around the fact that AviSynth can do it almost
immediately, even on non-interleaved files.
I'm curious to know if anyone has knowledge about this and if it would
be conceivable for FFmpeg to do it as quickly as AviSynth.
Of course I know non-interleaved AVI are not ideal but the fact is I
cannot do anything about my source of files.
Thank you very much for your help or answer,
