Answer 1

VLC does not embed FFmpeg as a sort of slave binary used internally, as you possibly could suppose. Instead, both FFmpeg and VLC are using libavcodec, a library which implement what ffmpeg exposes through its command line interface. So, FFmpeg supports VLC through supplying its libavcodec library to be one of the essential components on which the VLC is built as a player app.
