You should have a look at the "bmovl" filter. The manpage states you
can do a nice fading effect with it. Does it help?

	<alpha>
	Set alpha difference. If you set this to -255 you can then send a
sequence of AL- PHA-commands to set the area to -225, -200, -175 etc
for a nice fade-in-effect! ;)
	0: same as original
255: Make everything opaque.
-255: Make everything transparent.
