yes, also the outputs from my system may help you.

'h263|aac'
D aac ADTS AAC
DE h263 raw h263
DEVSDT h263
D VSD h263i
EV h263p
EA libfaac
D A mpeg4aac
Letter 'E' in the below exact lines from the output will tell whether
ffmpeg can encode h263 and aac. If it is not showing 'E', then there is
some problem on mapping libavcodec.
DEVSDT h263
EA libfaac
So here is one sample encoding from .avi to 3gp.
