Note that you are using "-map 0:0 -map 0:2", which makes ffmpeg select
exactly those two and only those two streams from the input.

If you omit any "-map" options, ffmpeg will select one stream of each
type fro mthe input (by its own measure of what is "best" or most
approriate).

If you specify "-map 0", ffmpeg will select *all* streams (from the
first input "0"). Note that this means that ffmpeg will also try to map
e.g. unknown data streams, and that the output format may not support
these.

This is described in more detail in this chapter of the documentation:
https://ffmpeg.org/ffmpeg.html#toc-Stream-selection


Just an additional small hint: Your ffmpeg is probably quite out of
date if it still supports libfaac. We recommend using a very recent
version, especially if you encounter problems. (And then, please also
provide the complete, uncut console output of your command.)

Cheers,
Moritz
