Does your command not work? You never said if it worked or not, and if
it does not work then show the complete console output. Otherwise how
are we to know what is wrong?

Since I know nothing about the ffmpeg you are using it is hard to
determine what the issue is. If you show your complete command and the
complete console output then we can give suggestions.

3GP can handle AMR or AAC audio, so if you can encode AAC audio then
you won't have to deal with AMR.
