Which of these is how AAC is stored in a iTunes purchased file? I would
like to the file to be as standard correct as possible =)

This gives me a huge file. Much larger than it input and Totem can't
play it.

> gst-launch filesrc location=file.mov ! qtdemux .audio_00 ! ffmux_mp4 !
> filesink location=file.m4a

Totem plays this file too slow. Do I need for adjust something?
