(b) Ummm ... probably not yet. The encoding of video, particularly the conversion to a completely different MIME type with proprietary extensions, is a complex task, unlike image conversion. Often, hardware capabilities are required. The closest I've seen is Freemovie-PHP [freemovie.sourceforge.net], but that just makes 'movies' out of JPEGs and such. Maybe there's a conversion utility out there to de-construct a movie into images and then you could build the movie with something like the above, but ... yeesh ... might as well just upload a real movie and link to it.
My 2 cents.
