i think making sws optional is a seperate thing, it might in rare cases

hmm, i thought sws should support both mplayer style and ffmpeg style img
formats externally ...

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
