Yes, indeed, thank you. Interestingly enough, I copied this bit
directly from mov_read_dfla in mov.c, so I'll send a patch for that as
well.

Not that I know of, but as I was looking at the file the with a hex
editor dfLa stood out as recognizable, as the MP4 spec uses it as well
(as Jan already commented). Therefore I copied most of the code from
mov_read_dfla, with some additions/changes as it is used in a
different context here of course.
