Ok. I never really understood when we should use one or the other, but
reasoning in terms of uint*_t is simpler.

I tried to stick with the same indentation, but it's not consistent
anyway (look at the "if" of this very file for instance)
In general, I find it's tricky in VLC to get a correct indentation,
since each module has a different one.

It would probably be cleaner, but when I saw that bpsAvg was
initialized to "-1" somewhere, I opted for this (lazy) solution :-)

I attached a new patch in case you want to apply it.
