I'm probably going to use lame for icecast and I'd like to stream
multiple bitrates of the same live music coming in the soundcard.
If one instance of lame were able to encode multiple output files from the
same input file/data (eg "$ lame in.wav -b 128 out128.mp3 -b 192 out192.mp3"),
could it possibly be substancially more efficient than several independent
instances of lame? Like are there some cpu intensive calculations that
would have the same or similiar results for different bitrates (perhaps
having the same output sampling rates) that could be reused instead of
multiple processes recalculating the same info?
Thanks!
