Yes, slightly. I've been using the script below in a user job (with cvlc
from VLC) to do a stream copy of H.264 video while transcoding the audio
from LATM to straight AAC.

I couldn't figure out how to get audio sync perfect, but that's not a big
enough problem for me (or WAF). I wonder if ffmpeg has stable mainline LATM
support planned for the near future?

mv $FILE.new $FILE
rm $FILE.old
