Patch
It looks like there are files with AAC audio that are missing the ESDS atom.
They play fine with QuickTime and other players. Attached patch creates codec
data from mp4a atom in case ESDS is not present.
Right now the patch assumes AAC LC, I'm not aware of any way to determine the
profile properly.
