demuxer: https://en.wikipedia.org/wiki/Demulti...)
A demultiplexer (often abbreviated as a demuxer or dmux) is a
software or hardware tool that creates two or more streams of
data from a single-stream input.
rawvideo: footage is the crude output of a video or still camera recording. It is the unprocessed data from a camera's image sensor.
-ovc:
-o = outfile Filename of the jpeg output images. This is a string that
is passed to the strftime(3) function and thus can
contain the format specifiers as documented in the
strftime(3) man page. The default is /tmp/%Y%m%d%H%M%S.jpg
-v = video
-c = count Number of automatic jpeg snapshots to take. Set this to
