According to that page, "This output device allows one to show a video
stream in an SDL window. Only one SDL window is allowed per application,
so you can have only one instance of this output device in an
application."
Personally, I think FFmpeg is useful because it does everything. It's
supposed to be heavy. But maybe the dependency chain could be cut
earlier, if that's important. Although, I think most systems will
include Qtbase for other reasons.
