Not directly with libavfilter + overlay.

What you could do, is to create a movie out of the logo, and make it
disapper/appear when it is convenient, not very practical but should

Also note that there is nothing preventing to implement the feature in
the overlay filter and I fancied to do that some times, please add a
ticket so it won't be discarded.

The format used is irrelevant for filtering purposes.
