Comment (by jeanhackman):
However, I was just successful in creating an MPEG-TS container with
MPEG-2 video and AAC audio including the "frm" audio language descriptor.
I think this will suffice for the testing I am performing. I'm assuming
passing "frm" audio language descriptor is either a limitation of the
MPEG-4 container ".mov" or a limitation within ffmpeg currently.
