and what is the problem
FlashBuilder AKA Flex was also used to build our companies
videoplayer and has no single problem with H264 videos, as
also for mobile clients they only have to be constraint baseline
and not main profiler
i have not generated FLV since years for such porposes

in which context does FlashBuilder not support AAC?
a valid H264 file has AAC per definition
well, we are playing thousands of different H264/AAC files
with our swf-player built with FlashBuilder
