Ok. The decoding was correct but the visible area was larger than
it should be. The attached patch fix this bug.
I just would like to know if such a usage of extradata is ok before
commiting it.

Note that reading the additionnal byte in vp6.c instead of flv.c is
not possible because swf.c also use the VP6F codec but don't have
the additionnal byte.
